Project Summery

While selecting my graduation project, I was clear towards the focus of either taking a project in Experience Design or I was seeking to work with the material Bamboo and explore it properties, understand the material and understand it relevance in today's scenario of heavy industrialization.

to me very relevant to the field of social and livelihood development through product development to do the final year project,as the organisation was working with a Tribal Community called "Kotwalia' and developing bamboo products through them.

As I was seeking for project in these two domains, I came across the memory of visiting vishalla, where we had happenened to meet the owner who curated the utensil muesum and also shared his initiative of curating a Chair Museum. He also had happened to propose us to be part of the initiative. Very later, I got in touch with the owner and shared the interest of working with him on curating the museum space and apply my understandings of experience design module. The proposal was accepted and I started working towards it. But as the time progressed,lot of tasks were added within the brief,which wouldn't have been able to work out within the project time duration. Due to the reason, I apologetically withdrew off from the project given the opportunity it was as well as not been able to do justice within the time and framework of academic duration.

After ending the previous project, I had happened to attend a seminar on Bamboo. There, I got acquinted with the various tribal development organisations of the state working with bamboo. Over there a particular organisation called CIBART (Centre for India Bamboo Resources and Technology) seemed doing major social livelihood enterprise driven project with a tribal community. The organisation seemed

Soon I got in touch with them and looked at the opportunity to do my project with the material and the aspect of working with the tribal community. They happily welcomed me to do my graduation project with them.

The brief was decided by understanding the context of tribals and their livelihood support through bamboo and by doing priliminary research, the direction of focusing on economic development of the tribals was taken into account. The basic outline of the design process was to understand the current livelihood development and organisation model, understand the current techniques, production setup, processes involved , exploring the given material, ideation and conceptualization, mock up models and their prototyping and later documentation of the whole process.

This being the first experience working in the bamboo based industry, my involvement with the organisation gave me a great opportunity to understand my role as an observer, thinker and maker, which enriched me as I progressed with the project of this nature.

After speaking and discussing the project flow and

intervention done at the organisation, with Mr. Amresh Panigrahi, I realised that the project still had to be more exploratory in order to seek for newer possibilities to work with the material, understanding and thinking about the flow of the product development and production process,due to which the project extended for long.

Following the process learnt at NID of research, ideation and form exploration to the sampling and bringing about my own(as well as bringing my own understanding and approach , guided me through my Graduation project .Working with CIBART gave me a chance to understand the design's implication towards a social group as well as the the people in the value chain.

Working with CIBART gave me opportunity to engage with the tribal community and understand their lives, livelihood through the material bamboo and how though me planning and hands on learning could I make the smallest change in the lives of the community I was interacting with.

Background Context Bamboo as a material Bamboo & Craft

Project Background Kotwalia Community is a primitive landless tribe living in southern piece of Gujarat .

There are vast no. of Kotwalia families dwelling in 19 talukas of six locale of Gujarat. Out of them 75% families are included in bamboo craft.Many of the conventional art things created by Kotwalia people group have ended up repetitive and have less market for it as there is an adjustment in way of life of individuals and approach of substitute items.

The Kotwalias generally cut green bamboos from the nearby forests and river banks and weave baskets from this raw material. Since no. of years the forests have receded farther away from the places of habitation of the Kotwalia community .

As a result, this is leading towards distress migration which is increasing at continuous basis which is leading towards monetary exploitation of migrants as well as susceptibility to communicable diseases.

The Kotwalia families continue to live in make shift homes of few twigs and plastic sheet while working on sugarcane farms in the most inhuman conditions where no facility for drinking water, electricity, primary health, food grain shop, anganwadi or any such basic infrastructure is available.

Kotwalia tribes only have access to primary education.

Their literary rate is about 26%. The basic education among the community is very low, with little access to higher education.Their low literacy rate leads to low level of employment. Almost all of them are landless since ages. Historically, this community does not have any productive assets. Its means for livelihood are unskilled labor work in agriculture, especially sugarcane fields.

The government has been taking initiatives to try tackling the problem of poverty and livelihood but still these problems persist within the tribal community. There is a huge scope for social development and the govt. of gujarat has highlighted key points under the Vanbandhu Kalyan Yojana which would be looked into for the overall human and economic development of Kotwalia community and it is also aimed at doubling of the income of the tribal area and creating conditions for their sustainability.

The policy covers all tribal people and all areas with tribal population across the country.

It also focuses on achieving defined outcomes in socio economic development of tribal population.It also has focus towards gender responsiveness.

The pointers gave defined directions and opprtunities to understand the linkages of the stumbling blocks of development and opportuntities for enhancing the livelihood throigh craft intervention.

The further step was to look at all the defined points from VKY( Vanbandhu Kalyan Yojana) and do priliminary brainstorming so as to understand what areas were potential to focus on. By looking at each areas, I could get a glipmse of the possible linkages which could be focused on for better refining the brief. All the areas seemed very potential to be converted into appropriated briefs. While discussing these directions with my guide, it become much clearer so as to scout for in each of the points defined in Vanbandhu Kalyan Yojana.

Economic development and education seemed relevant areas as I identified few linkages which I could explore later in primary or field research.

In education, I could think of possible connections with tangible intervention with social and livelihood development with the tribals. Economic development seemed to be a large area as the project was taken up to explore the social and livelihood enhancement aspect with kotwalia tribe in perspective.

Further I had to formulate the questions which were crucial in order to be answered while engaging with a project of this nature as well as addressing the solutions generated by the end of the project.

Problem Setting While doing priliminary brainstorming of areas defined under VKY, the questions below were defined so as to create query for my project which I had to answer through my research and further development in the project :

How can I help in the economic development of craftspeople through my study & research in their livelihood generation by connecting the locality to encourage tourism leading to economic development?

What are the existing challenges in education of Kotwalia & the other tribal community that can be addressed with Bamboo ?

How can the existing problems of human and economic development be addressed through design thinking which can resolve visible problems?

How can the learning experience of higher education be enhanced through bamboo craft intervention?

How is the community getting benifitted from the setup and what aspects of economic development can I understand and venture?

What are the gender based activities in terms of craft, taking place and how the gender & social issues could be resolved for social development through skill based intervention?

Taking in the context of CIBART's workshop setup and Kotwalia community, I realised that formulating my initial brief towards livelihood development would allow me to understand the critical linkages which I can touch upon as the project would progress.

Design Methodology The project started with the secondary research about the organisation as well as the crafts community. The project deliverables were eventually supposed to be as tangible output, as the focus was towards livelihood developement and economic development through product based intervention, assessing the existing skill, and machinary available at the organisation.

Secondary and primary studies were also done to look at the present contemporary market in the Bamboo product domain at large and understand the relevance of bamboo in today's context.

The research focused on understanding the value chain in terms of unit production processes, and acquiring the understandings of quality control as well as looking into methods of standardisation of production stages. To understand the various facets of livelihood development in the tribal industrial craft context, systematic research was done that further

informed towards the product development process.

Further, research articles were referred from various experts in the area for gaining more deeper insights to establish the factors which would address the various aspects,which were to be covered during the production and unit processes.

Hands on approach was implimented to understand the material and its usage, while doing observational study of how the material was taken from a raw material stage and through production processes and finally leading to manifestation of a tangible product with an intended utility. By understanding the opportunity areas, the brief was generated by looking at the potential of the material as well as the spatial context, which could base the platform for spatial interaction.

The explorations were analysed to understand what areas could be made potential to be taken further towards product development direction .

While engaging with the material and the tribal

community, various factors were looked at, from the unit processes to the engagement of the tribals with the exploratry prototypes which were being tested and developed.

Towards the development of tangible products, lot of production factors which were creating issues, were tackled by consulting to the guide who helped in the resolution of the issues by addressing the various aspects from development of a form language, to the value addition to the material, thus resulting in manipulating the perception of the products.

After going through the process of defining the context and narrowing down the potential areas as well as defining the initial brief, the next task was to build a platform to create a context for development at the organisation. The platform was supposed to be establised, first through secondary and later primary research into the subject. The secondary research created a query to understand the material and its various attributes and understand its potential towards the academic project.

Bamboo Bamboo is considered amongst grass family, which are found in tropical and sub-tropical regions of the world. It is also the fastest growing grass in the world. Bamboo belongs to the family of grasses. Grasses are plants, which typically have one seed leaf and continue to grow with narrow leaves from their base. Unlike trees, bamboo had no radial fibres, therefore it splits easily along the length.The only resistance to splitting is at the nodes,because this is where the fibres cross over briefly.

The family includes “true grasses�, sedges and rushes. Thin culms with narrow cavities are popularly used as umbrella handles, fishing rods and flutes, while mature culms are widely used in constructing mud huts, mats, baskets and fences. It's the fastest growing plant in the world and can grow 1-to-4 inches in a day and regrows quickly after being cut down, making it the one of the most renewable resources.

Bamboo grows in diverse climates from hot tropical regions in Asia, African and Latin America to the icy mountains of Indian Himalayas. Because of its fast growth, good mechanical properties, low price and abundant availability, bamboo is widely recognized as a promising resource for sustainable development.

Anatomy

To understand the whole material,it is necessary to look at the constituent parts, and in this case it was important to understand bamboo by looking at the various aspects of the grass and define their characteristic and seek for better understanding of it as a material. As, discussed earlier, Bamboo is a perrenial evergreen that is part of the grass family (a very tall and woody grass ).

Similar to grass, bamboo is characterized by a jointed stem called a culm.

Typcally the culms are hollow but some species of bamboo have solid culms. Each culm segment begins and ends with a solid joint called a node.

Nodes are are characterized by a swelling encircling the ends of the culm segments. The segments between the nodes are called internodes. From the nodes grow leaves and branches. Similar to the culms, the branches are also segmented with nodes and internodes.

The infographic on the right was created to basically highlight the various form aspect of the plant to inform about its sturcture and physicality.

the culm/ internode The tubular forms, prominently visible are most commonly used part of the bamboo plant. The basic structure of each culm is common to all species of bamboo.

bamboo leaf The leaves of the plant produce food through photosynthesis. The green part of the leaf is called the blade.It is attached to a leaf sheath which encloses and protects the new leaf while it is growing.

node the nodes are swollen portion between the internodes. These transverse membranes completely separate each internode. These vessels and fibres that are unconnected in the internodes pass through the transverse wall, cross connecting the wall of the culm.

culm sheath Culm sheaths are tough and fiberous leaf-like structures that encase the growing bamboo internodes. The sheaths are attached on opposite sides of alternate nodes, so they overlap to completely encase and protect the young shoot while it is growing.

rhizome Bamboo culms grow from underground stems called rhizomes of which there are basically two types : Monopodial type & Sympodial type

Properties

The properties of bamboo can vary much from species to species.

In plant form, bamboo is naturally resistant to a wide variety of pests and fungi, which means it can grow without the use of any chemicals or pesticides whatsoever.

Bamboo absorbs more carbon dioxide, and releases 35% more oxygen into the atmosphere than an equally sized grove of trees.

After harvesting, the roots of the bamboo plant remain in place.

This prevents soil erosion, which would otherwise clog rivers, streams, and other important waterways, potentially damaging century-old ecosystems.

The properties of bamboo culm changes as it grows , making it more suitable for different applicarions at different ages.Young bamboo shoots are soft,tender and starchy.The shoots are tender when they are young, because bamboo's cells get lignified as it grows, cuases the culm to harden.

National Institute of Design

Graduation Project Doc.

Young bamboo shoots are softer at this age and have a high percentage of starch content.The shoots are tender when they are young, because bamboo's cells get lignified as it grows, causing the culms to harden.One year old bamboo has fresh green colour,with the culm sheaths intact on the lower half.

Bamboo is flexible and easy to sliver.Starch content is lower than that of young bamboo,making it more resistant to borers. At this ages makes it ideal material to be interlaced into mats and baskets. The starch content can be easily removed through leaching and similar treatments,making sliver based applications ideal for bamboo at this age. Bamboo at this age is also preferred for the pulp and paper industry.

Bamboo reaches its optimal strength at the age of three to four. At this age,its ideal for the use in furniture and construction. For construction purpose,best harvested just after the shoots have emerged.Four year old bamboo is quite hard and resistant to insect attack due to the starch being provided to newer culms and thus older culms receive less starch.

Bamboo culm at this age begin to lose the strength.This continues until the culm dies between the age of six and twelve.

Tensile Strength

Elasticity

Bamboo is able to resist more tension than compression. The fibres of bamboo run axially. In the outer zone are highly elastic vascular bundles that have a high tensile strength. The tensile strength of these fibres is higher than that of steel, but it’s not possible to construct connections that can transfer this tensile strength. Inside the outer skin which has high amount of silica content, parallel elastically fibers with a tensile strength up to 400 N/mm2 can be found. As a comparison, extremely strong wood fibres can resist a tension upto 50N/mm2.

The accumulation of highly strong fibers in the outer parts of the tube wall provides good elastic modulus to the grass.This aspect looks at the tension, shear and bending strength of the material. Smaller bamboo have stronger mechanical properties,whereas larger bamboo can withstand larger forces.

The higher the elastic modulus, the higher is the quality of the bamboo.

Also as the

Compressive Strength

Fire Resistance

The smaller bamboo possess better material properties due to the fact that bigger tubes have got a minor part of the outer skin, which is very resistant in tension. The portion of lignin inside the culms affects compressive strength, whereas the high portion of cellulose influences the buckling(heat bending) and the tensile strength as it represents the building substance of the bamboo fibers.

The fire resistance of bamboo is very good because of the high content of silicate acid. Filled up with water, it can stand a temperature of 400 degree celsius while the water cooks inside.

Durability Without any protective treatment, most bamboo species have an average natural durability of less than 2 years. Stored under cover, untreated bamboo may last 4-7 years.These variations in bamboo durability strongly depend on the species, the length of the culm, the thickness of the wall, but also, and equally important, the time of harvesting.

Types

There are more than 90 genera of bamboo can be found growing naturally on all the continents excepts Europe and Antartica. Bamboo grows in diverse climates from the hot tropical regions in Asia, Africa and Latin Americato icy mountains of the Indian Himalaya but is most abundant in Southern Asia. Bamboo culms grow out of horizontal, underground, stems called rhizomes.

Shoot structure of bamboo The bamboo rhizome is the underground part of a bamboo stem (culm). However, rhizomes are not roots, roots grow under the rhizome and culms erect on top of the rhizome. Axillary buds on the rhizome can produce new rhizomes, or bamboo shoots which grow into culms. Just like the culm, rhizomes have nodes and internodes. There are basically 3 types of bamboo rhizomes :

Form & Function

Bamboo’s circular structure makes it stronger than a similar weight of other woods, and since ages, it has been used as a construction material for houses, flooring and furniture.

Bamboo is a very complex material and there are many forces which inform its form including: direction,moisture content,diameter,wall thickness,distance to the node, height, age and species.

In terms of diameter and wall thickness, smaller bamboo has stronger mechanical properties (such as ultimate compressive strength) for its size. However, larger bamboo can withstand larger forces. Thicker walls have better mechanical properties. As the distance to the node decreases, the mechanical properties improve.

The height along the bamboo (when measured from the ground) affects its properties. Generally, the part of the bamboo nearer the bottom has stronger properties. The stems, or 'culms', can range in height from a few centimetres to 40 metres, with stem diameters ranging from 1 mm to 30 cm.

There have been various documented uses of bamboo given its circular form and the strength of the culms, their straightness, smoothness, lightness combined with hardness and greater

hollowness & also the aspect of its regularity with which bamboo can be split, the different sizes, various lengths and thickness of their joints,which makes the bamboo as a material,suitable for numerous end products and purposes. The bamboo culms have been extensively used in applications such as flooring, ceiling, walls, windows, doors, fences, housing roofs, trusses and rafters; it is also used in construction as structural materials for bridges, water-transportation facilities and skyscraper scaffoldings due to mechnical properties and compressive strength.

The physical aspect has also been utilised to develop products ranging from domestic household products such as food containers, skewers, chopsticks, to handicrafts, toys, furniture, flooring, boats, charcoal, musical instruments and weapons.

Bamboo fibers are used to make clothing, sheets and towels, and people seeking eco-friendly alternatives to metal and plastic are using bamboo to make machines, bicycles, pumps and other practical, everyday products.

The microscopic characteristic of bamboo culm The structure of a bamboo culm in the transverse direction is characterized by numerous vascular bundles embedded in the parenchymatous ground tissue. The total culm tissue consists of 50% parenchyma, 40% fibers and 10% conducting cells.

The parenchyma and conducting cells are more numbers in the inner third of the wall, while the percentage of fiber is higher in the outer part. In the vertical direction, the fiber amount increases from bottom to top with the decreasing parenchyma content.The bamboo fibers are supporting/protective tissue with thicker wall, long and tapered at their ends.

The main chemical constitute of bamboo are cellulose, hemicellulose and lignin, which amount to over 90% of the total mass. The minor constituents of bamboo amount to 10%, which are composed of resins, tannins, waxes and inorganic salts.

On both sides of bamboo culm wall are covered by a special tissue.

The outermost skin of the bamboo culm consists of epidermal cells that are covered with a waxy layer of Silica which has poor affinity towards water and adhesives. Silica content is the highest in the epidermis, with very little in the nodes and is absent in the internodes.

The innermost skin 'Lumen' is the part of culm wall next to culm cavity. It is composed of sclerenchyma cells.The bamboo fibers are Protective tissue with thicker wall, long and tapered at their ends.

They contribute 40-50% of the total culm tissue. The fiber length of bamboo varies from 2 to 4 mm.

The density of bamboo increases from inner to outer part and from lower to upper part of the culm. Moreover, the density of nodes is higher than that of inter-nodes.

Durability / Preservation

The durability of bamboo in comparison to wood is short if the material is not treated and is exposed to the atmosphere can be lead to fast degradation. It also needs to placed under the cover for the period of 6 to 12 weeks depending on the season to avoid from cracking by exposure to sun. Precaution needs to be taken as bamboo can very much attract fungal growth if coming in exposed to moist weather.It is also found that more than 40 percent of bamboo is being destroyed due to biological agents if stored in untreated conditions.

Variation in durability has also been observed along the length of the culm and the thickness of the wall. The lower portion of the culm is considered more durable, while the inner part of the wall deteriorates faster than the outer harder portion. This is probably related to the anatomical and chemical nature of the woody cells.

The durability of bamboo can be enhanced by uasge prevention methods with or with the use of chemicals.Traditional methods are water curing and smoke curing.

Chemical methods are spraying of the chemicals,soaking bamboo in boiled water for hours till the starch content of the bamboo escapes from the culm.

Bamboo consists of 50-70s hemicellulose, 30% pentosans, and 20 25% lignin.Ninety percent of the hemicellulose is xylan with a structure intermediate between hardwood and softwood xylans. The lignin present in bamboos is unique, and undergoes changes during the elongation of the culm Bamboo is known to be rich in silica (0.5 to 4%), but the entire silica is located in the epidermis layers, with hardly any silica in the rest of the wall.

Bamboos also have minor amounts of resins, waxes and tannins. None of these, however, have enough toxicit to impart any natural durability. On the other hand, the presence of large amounts of starch makes bamboo highly susceptible to attack by staining fungi and powder-post beetles.

The natural durability of bamboo is very low and depends on species, climatic conditions and type of use. The natural durability of untreated bamboo poles is low. For most species less than 2 years, and 4-7 years under ideal conditions (without exposure to sun and rain). The preservation of bamboo poles is therefore essential to extend its service life.

Bamboo Shrinkage Properties (cracking / splitting) An important feature of bamboo is the way it reacts to different temperature or humidity changes, as this may result in splits or cracks in the bamboo pole. Bamboo is an anisotropic material, as in that the properties in the longitudinal direction are completely different than those in the transverse direction.

The longitudinal direction is made from bamboo cellulose fibres which are strong and stiff. In the transverse direction bamboo consists mainly of lignin which is soft and brittle. Therefore, bamboo is perceieved to be one-sided reinforced composite with relatively little tangential capacity.

The shrinkage of the nodes is 4 x higher than the shrinkage of the internodes.This may be because of the large amount of reinforced fibres, which are present in the internodes but less in the nodes.

Because of the differences in anatomical structure and density, there is a large variation in tangential shrinkage from the inner (10%) up to the outer part (15%) of the culm wall.

Thus, the tangential shrinkage is higher in the outer parts of the wall than in the inner parts, which can lead to cracking.

Equilibrium Moisture Content Bamboo is a hygroscopic material which means that it will absorb or expel moisture from or to its surroundings until an equilibrium is reached. The moisture content thus varies according to the properties of the surrounding air.Water is held in bamboo in two ways; free water which is retained in the cell cavities, and bound water which is retained in the cell walls themselves.

The moisture content of the culm wall is higher in the inner portion than in the outer portion.

The nodes have lower values than the internodes. These differences can be up to 25%.

During drying bamboo loses free water until its moisture content is about 15%. The bamboo will shrink if the remaining water is driven out, but the bamboo can swell again after drying when moisture is recovered from the relative humidity of the surrounding air.

Bamboo Deterioration Bamboo deterioration is mostly caused by non-biological as well as biological agents during storage or in service. Split bamboo is more rapidly destroyed than round bamboo.

The inner part of the culm is severely and easily attacked than the outer one due to its difference in anatomical characteristics,chemical composition.The waxy siliceous coating on the outer surface provide some protection to the outer part. The large amounts of starch present in bamboo makes it highly attractive to mold and fungi, termites and powder-post beetles. They cause much damage during drying, storage, and subsequent use.

The intensity of deterioration also depends much on the bamboo species, duration of storage, mode of use and prevailing environmental and storage conditions. Damage in bamboo can be caused by any or a combination of the following agents of deterioration.

Non Biological Agents The large amounts of starch present in bamboo makes it highly attractive to mold and fungi, termites and powder-post beetles. They cause much damage during drying, storage, and subsequent use.Different kind of agents can act against the material and can cause it to deteriorate.The ultraviolet radiation and heat can affect the exterior surface & can cause the surface to change its natural colour.

Chemicals like strong acids and alkalies can cause chemical reaction in the tissue structure.

External pressure applied on the surface can cause cracking longitudinally.

Biological Agents There are three major groups of fungi that cause biological deterioration Surface Moulds

Soft rot fungi

Many fungi may cause stains on bamboo culms, particularly when the culms are exposed to excessive humidity and lack of sunshine.

Fungi of this group also derive their food from simple sugars but they penetrate deep inside the bamboo tissues. The affected materials appear brown, grey to black in colour.

Fungi under this group are normally found on the surface of the affected material and derive their food from simple sugars which occur in freshly cut bamboo. These attack bamboo culms exposed to high humid conditions. Moulds reduce the aesthetic quality of freshly cut bamboo and finished products, while these are in storage, transit or in usage. Materials that are damaged show a change in colour which may be black, greyish black.

This group of fungi utilises lignin and cellulose in the secondary cell walls and produces cavities which are conical or spindle shaped. Affected bamboo becomes soft when wet and shows charred appearance when it is dry.

Bamboo Insect infestation Untreated bamboo, just like almost any other wood, has a high chance of being attacked by insects. Bamboo insect infestation occurs due to the presence of starch and other carbohydrates. Insects obtain their food supply from the bamboo and degrade it, therefore bamboo should be chemically treated to avoid infestation.

Termites Powdery dust falling out of holes indicates ongoing bamboo insect infestation. The beetle larvae can tunnel through the entire inner tissue leaving behind only a thin surface of the hard cortex which may give a false impression when evaluating the significance of damage for repair work.

Termites live in organized colonies having a population of several thousands to a few millions of individuals. They are among the few insects capable of using cellulose as a source of food. Some varieties of termites (subterranean) need high humidity and access to water for survival. Other types (drywood type) survive without ground contact, obtaining moisture from the culm.

Preservation of bamboo Bamboo is subject to attack by microorganisms and insects in almost any construction applications.

The decay and biodegradation of bamboo culms during outdoor storage can be checked to a great extent by adopting a good storage yard practices. Culms should be stacked horizontally over raised wall to facilitate water drainage and air circulation.

For reed bamboos, vertical stacking results in a small gain in pulp yield over horizontal stacking because the former suffers less fungal damage. The service life of bamboo is therefore, mainly determined by the rate of attack.There are variety of methods to improve the durability of bamboo on the basis of chemical usage as well as the method of treatment.

To get a more clearer understanding of what types of decay can occur when cut for use, further insights were explored through secodary research.

For the preservation of bamboo as a material, there are various methods which were informed to be utilised for the treatment of the material. The methods were divided in two types -

Short term

Long term protection

Short term protection In terms of protection measures, one of the insights was gained that properly stacked bamboo under a shed would ensure uniform drying and prevent any moisture increase due to rain or water splashes. The short term measures taken by the tribal community was to cut the poles in smaller lengths and dip them into a boiling container so as to remove the starch content.

This technique is not much effective in comparison to chemical treatments as there is a great possibility of attack by bores and insects. There are other traditional methods which have been adopted for treating bamboo i.e Smoking, Curing, White washing, Soaking.

72

National Institute of Design

Graduation Project Doc.

Smoking

Curing

Traditionally, bamboo culms are placed above fireplaces inside the house so that the smoke and heat rises up and both dries and blackens the culms. It is possible that the process produces some toxic agents that provide a degree of protection.

Alternatively, the heat generated by the fire could possibly destroy or reduce the starch content of the parenchyma cells by pyrolysis. This is considered an effective treatment against insects and fungi.

Bamboo culms are treated during or immediately after extraction and before stacking in the storage yard. Curing involves harvested culms, with branches and leaves intact, in open air. The leaves continue to transpire causing the starch content of the culms to fail.

White washing

Soaking

Bamboo culms and bamboo mats for housing construction are often painted with slaked lime. This is carried out mainly to enhance the appearance, but there is also an expectation that the process will prolong the life of the bamboo structure by preventing moisture entering the culms. It is possible that the water or moisture absorption is delayed or in some cases prevented which will provide a higher resistance to fungal attack.

In Indonesia, bamboo mats are tarred and later sprinkled with a layer of sand. When this is dry, upto 4 coats of whitewash are applied. Plastering is also a common practice using cow dung mixed with either lime or mortar.

In this technique bamboo are submerged in water for about 6 weeks. This method increases the durability of bamboo, according to a local belief, by 10 years. It is believed that since starch is soluble in water, by submerging the starch gets dissolved. Its a safe and effective non-technical approach but it is time consuming as well. Also, to do this a large scale it would be resource consuming as transportation factor will also be accounted. As the water is still trapped in the tissues, there are chances during shrinkage for the cracks to occur. For this reason this method cannot be held for long term protection.

The bamboo poles are made to drop in water bodies for weeks till the starch content gets dissolved

Long term protection There are various methods through which bamboo as a material can be preserved but mostly through chemically treated methods. These methods ensure longivity of the material when in use as the major task is to remove the starch(cellulose) content from the lumen, in order to prevent it from attack from insects.

Bamboo culms are divided into nodes and internodes and are composed of two types of tissue; parenchyma cells and vascular bundles. The vascular bundles consist of vessels which are thick walled fibres and sieve tubes and it is through these that water movement takes place in the living plant.

In Modified Boucherie Technique, (aka. sap displacement technique), pressurised preservative solution is applied on the basal end, which pushes the sap contained in the vascular bundle out and then replaces it with a preservative solution. The hydraulic pressure pushes the chemicals through the wall of fresh bamboo and thereby the sap is drained out and replaced with the chemicals.

Vaccum Pressure

Steeping

This method results in complete penetration of preservative across the wall thickness of bamboo.

However, it is more expensive as it requires a boiler and a steaming chamber.

The plant can treat bamboo up to 20 feet tall. The tank is filled with bamboos (up to 60-90 poles) and supplied with steam mixed with 25 Boric acid solution and 2 % Borax chemicals in water.

The whole process takes up to 3 hours. After the treatment the tank is opened after 2-3 hours so that the temperature inside is cooled down.

Then the nitrogenous products, which ooze out of bamboo, are wiped out. The bamboo due to steam absorbs the chemicals and thus become borer or termite proof. The pieces are dried under the sun on the bed of sand.

In this method, the bamboo poles are initially cut into desirable sizes and later dipped and soaked in chemical preservatives without making them float for 10-15 minutes. The nodes can be drilled on the opposite sides near the nodes of the the culm.

This method involves keeping the green bamboo completely submerged in the preservative solution.

The specimens were kept submerged in water for about a week before treatment. Both round and half-split specimens were treated for a period of up to 50 days.

The micro to macro aspects of Bamboo were realised while reading about the plant and understanding the various subject of its growth pattern, properties and anatomy.

The understanding and analysis of the durability and preservation aspect of bamboo created the understanding that even though the material seemed to show a lot of potential in terms of its elasticity ,compressive strength and its comparison to steel, it

had negative aspects in terms being affected by biological and non biological agents, resulting in negative perception towards Bamboo as a material in the society.

The study of preservation methods generated the understandings of steps taken across the various bamboo growing and harvesting regions to conciously look into the longivity of the usage of material in order to position it with already establised natural material, such as wood.

The micro aspects generated the understandings of the internal structure of the material which informs its usage as a material and also informed about the various physical aspects which were not been acquinted with before.

After a brief understanding of various properties of the grass, the next stage was to understand its presence in the world, its relevance in the society today, the various industries which are thriving towards development with the material,its perception and its relevance to communities which use it to generate economic and livelihood benefits.

Bamboo species are found in diverse climates, from cold mountains to hot tropical regions. Between 1,200 and 1,500 species of bamboo have been found so far and they grow all over the world, depending on what kind of climates the particular species can tolerate.

The total bamboo area in the world is approximately 36 million hectares or an average of 3.2% of the total forest area.

Bamboo is mostly distributed in the tropics, subtropical and temperate zones of all continents except Europe and North America. There are species of bamboo that can survive winter weather up to -20° F and still grow again in the spring during the normal germination periods. Most commonly, bamboo is found in places that qualify as tropical, sub-tropical, or temperate zones. These are places like Southeast Asia, South America, and the Southeast portion of the United States. Some species of bamboo have been known to grow well indoors in less temperate parts of the world.

These 'needs' manifested itself in the form of collecting, hunting and storing and adorning. These needs were the forces that informed these communities to investigate the material and explore it to derive meaningful purposes.

Initially being made and sold locally for generating livelihood, these objects held an important status in the societies till the mid of 20th century.

As the industrial age progressed with the advancement of technology and mass production of objects started taking place which focused majorly on standardisation, availability of raw materials and incorporating industrial setup at a large scale.

The industrial revolution and the spread of western knowhow meant our economies started depending on minerals,metals and economic agricultural commodities like cotton and jute.

The spread of technology and formalised knowledge meant a reduction of local knowledge of traditionally used materials including bamboo.

Thus the need of the material through the crafting of product started declining in various parts of the words.

http://brightwill.en.tradevv.com

Due to the local availability of the grass amongst the vast communities around the world, the grass was explored majorly as a material for making utilitarian object that served various purposes according to their needs.

But with the changing times with globalised economy, there has been a revival for the demand of the products made from the plant.

The traditional knowhows have been coming back and are being appreciated Before the 1990's major thrust was on the development of new materials for industrial as well as for general applications.Being the first choice for the development of synthetic polymers and reinforced composites, low cost petroleum raw materials played an important role.

However after the 1990's, adverse environmental impact of synthetic components, depletion of petroleum resources and development of advanced techniques shifted the interest of industries and researchers towards biobased materials.

In the need of cost effective engineered materials and environmental conciousness, research continued on the development of natural fiber composites for different applications like packaging material, building material and other various applications of which bamboo has been playing a major part.

Bamboo & World Trade The world bamboo market is currently worth USD 7 Billion/year, of which China has USD 5.5 Billion. The largest markets are handicraft (USD 3 Billion), bamboo shoots (USD 1.5 Billion) and traditional furniture (USD 1.1 Billion).

Traditional markets cover handicrafts, blinds, bamboo shoots, chopsticks and traditional bamboo furniture, which count for 95% of the market.

Emerging bamboo markets are wood substitutes such as flooring, panels and non-traditional furniture.

The growth of the global market is expected to grow to USD 15-20 Billion/ year in 2017. Non-traditional markets are expected to claim 45% of the total bamboo market. In 1992, France, Germany and the Netherlands were the major markets for bamboo, collectively accounting for 53% of the world’s total imports. Traditional markets cover handicrafts, blinds, bamboo shoots, chopsticks and traditional bamboo furniture, which count for 95% of the market to date.

New market products include modern/laminated furniture, flooring and panels cover the remainder 5% of the bamboo sector.

America & Europe (Largest western market) America and Europe are the two regions represent the largest Western markets, accounting for up to 80% of the global bamboo trade.

Because of the relatively high prices paid for industrial bamboo products and their growing market share, more bamboo producing countries intend to develop modern bamboo industries for products such as panels,paper, fabrics, charcoal and shoots.

Bamboo poles & strips market The market for bamboo poles and strips for various uses in the USA is estimated at US$15 million (90% from China), 30% of which is used for decorative purposes in gardens and parks; garden wood, fences, gates and gazebos.

This product group of garden and parks accessories has bigger potential for USA market than for the EU. The tropical appearance of bamboo products highly appreciated in the USA than in the EU, where bamboo is perceived more as a niche product for specific purposes, for example in zoos and theme parks.

Future projections of market prospects for basketware remains positive, as imports should continue to benefit from an increasing conciousness and campaigns for natural materials and handicrafts.

Bamboo composites market Bamboos cut into strips being used for producing the bamboo strip products such as glued laminated bamboo, also called Laminated Bamboo Lumber, is showing postive tangible perception of high strength and stiffness and is used in applications of material for construction and design of thinner structural elements than those made of wood.

A global shortage of certified renewable wood and shortage of all wood kinds in Asia is opening up opportunities for substitute products in the form of bamboo laminated boards.

Growth in interest in sources of environmentally friendly energy such as biomass have an effect on wood-based industries and positive potential of bamboo to have an impact.

Numerous studies have documented expansion of household incomes and poverty reduction through increased bamboo production.

Overall trends in the export market for Bamboo products appear favourable for the expansion of efficient industrial units into the sector.

It is envisioned that Indian industries producing Bamboo products can eventually capture a significant portion of this market owing to the provision of indigenous designs, capitalising on the exoticism associated with tribal crafts and eventually on reputations for best practices and high quality. This is of course contingent on the development of Brand Names, which requires the establishment of a strong industrial structure capable of creating value added products of high quality at competitive prices.

In combination with estimates of market size, this provides an initial assessment of the demand side attractiveness of the different markets in terms of market accessibility.

Bamboo-based composites will become a highly competitive alternative to wood-based composites and will become an important forest based product in the future.

Statistical data on International Bamboo Imports

These import data suggested that there has been steady rise in the the consumption of bamboo products in western market in various product catagories and is steadily changing the preconceieved notions of bamboo in the past of being associated with rural crafts and being cheap.

Insights were derived from these data that there has been a consistent rise in the market demand for the material and is going to double by year 2017. In the emerging market, furniture and panels made from laminated bamboo board just accounted for 5% of the market,suggesting the greater relevance of products made from traditional handicraft methods.Industrial bamboo products are being paid higher. The research also suggested that the bamboo based composites were competative alternatives towards wood based composites projected for the future.

Bamboo Industry in India India is the second richest country in bamboo genetic resources after China. These two countries together have more than half the total bamboo resources globally.There are over 136 species of bamboos occurring in India. Fifty-eight species of bamboo belonging to 10 genera are distributed in the northeastern states alone.

In India, 13.47 million tons of bamboo is harvested annually of which 11.7 million tons is utilised industrially in paper mills, as scaffolding or fencing, for internal consumption in bamboo-growing households, handicrafts and miscellaneous items like incense-sticks, ladders, icecream sticks, agricultural implements, etc.

About 1.9 million tonnes is used by the pulp industries.

To achieve this there is a need for consistent supply of processed bamboo, development of industry, channeling of raw material into manufacturing system and an assurance of steady market .

Trade regulations for bamboo are usually the same as those for wood both at international and regional levels.

The vast amount of Bamboo resources, the second largest in the world, indicates the presence of a vast pool of untapped resources, due to regulation barring access to these forests resources.

Bamboo in India remains a material for personal usage in homes; the only products produced industrially are produced by small firms lacking in sufficient capital to pursue value addition or quality enhancement. The association of Bamboo with livelihood promotion remains confined to handicrafts promotion, as a result of which even government programmes fail to appreciate its industrial potential. In addition, archaic and confusing regulatory regimes as well as conflicting legislation prevent Bamboo from reaching its true potential.

Due to the abundance of the natural product, small holders harvest the bamboo from the edges of their farms and their surroundings; there is negligible large-scale commercial cultivation of bamboo in India.

Through more studies it was understood that the resurgence of bamboo was still possible, and this was based on evidence of significant new and contemporary economic opportunities that have emerged over the past decade.

On average, 250 air-dried culms weigh one tonne and the price per tonne of dry bamboo is Rs 1000 (auction rate) (about US$ 22).

86

The annual market for value added bamboo in India is estimated at approx. 1.0bn USD in 2004 which is expected to grow up to 5.8bn USD by 2015.

Bamboo industry's product diversity

The set of all firms engaged in the addition of value to bamboo through production of igh value products could be defined as bamboo industry in India. The industry in terms of its product diversity can be classified into the following sub-sectors :

Handicrafts

Bamboo Shoots

Construction

Industrial Production

Handicrafts in bamboo sector can be characterised by manual processing of the material after cutting and felling and high value addition to limited quantities of Bamboo.

High value agricultural food crops that can be grown parallel to the culms.

In terms of construction, bamboo is utilised in either for traditional construction or sold through timber marts to constructors.

This involves the mechanised and semi mechanised processing of larger volumes of culms, which offers large opportunities for major growth and pro-poor impacts on rural farming communities. This sector can further be divided into :

Premium Processing

Medium Value Processing

Low value Processing

Unprocessed Culms

Premium processing in the terms of bamboo industry invovles in the development of high value products and requiring facilities for primary and secondary processing as well as high level of finishing. Exp. Bamboo flooring, laminated furniture,

Medium value processing requires less capital intensive processing than above.

Exp. Matboards,chopsticks.

This type of processing is done to products invovling limited value addition to bamboo culms.

Exp. Charcoal and Paperpulp industries

These unprocessed culms are utilised in traditional applications such as scaffolding and traditional construction as the only utility is to provide structural support.

utilitarian purposes, the advancement of manufacturing processes and the ease of making mass produced object has challenged the livelihoods and material culture of these communities, thus leading to the decline of craft objects made by the skilled ones belonging to the communities who livelihoods depend on the material.

The fact that Bamboo species are distributed across the country reflects the enormous potential Bamboo has for the development of a pan-Indian industry based on local sourcing of raw materials, and towards the potential for the Bamboo sector to achieve near- source value addition.

The presence of near-source value addition in modern value chains conveyed that the industrial component of the Bamboo sector has an excellent potential in terms of its pro-poor impact in poverty alleviation. The industrialisation of the Bamboo sector is, thus, an essential task for Bamboo to have any true effect on the lives of the millions who depend upon it.

Bamboo value chain in India There is a variable length and size of the value chain for Indian Bamboo based product industries, occuring primarily due to the different structure of the processing chain for different products. The generalised Indian value chain is elaborated here.

Resposible for growing bamboo or procuring it directly from the forests

Cultivator

Aggregator The Cultivator provides the Bamboo produced to Aggregator Middlemen, who are responsible for the collection of Bamboo and sorting of this Bamboo depending on its grade in terms of quality. In some cases, very basic levels of processing are performed at this stage too.

Manufacturers purchase the Bamboo at up to 400% of the price received by the cultivator. The bamboo they receive is, in general, poorly sorted, unprocessed and variable in quality (leading to wastage rates of up to 50%)

The Aggregator Middlemen provide Bamboo to traders, who are involved in transportation of Bamboo to bazaars in large urban centres, where manufacturers are willing to purchase them.

Bamboo in Gujarat Gujarat is located in the western part of India, and situated in the arid and semi-arid zones of the country. The forest growth varies from scrubs and thorn forest of north and north-western part of Gujarat to thick forest in south Gujarat. The occurrence of bamboo as an under-storey is a natural component of many of the forests.

There are 22 reported species of bamboos reported from the State; the dominant species are Bambusa arundinacea (Katas or Thorny bamboo) and Dendrocalamus strictus (Manvel or Solid bamboo). Dendrocalamus strictus is economically the most important. It is found in the dry deciduous forests over a large part of the State.

Bambusa arundinacea is found in mixed moist deciduous forests as well as in the moist dry deciduous forest of the State.

The artisans of Gujarat are involved in making bamboo products mainly with these two species.

Bamboo communities of Gujarat

A tribal women observed making long strips of longitudinal section for the purpose of weaving ,while visiting one of the tribal villages where these Kotwalia's reside.

In the district of Dangs of Waghai, Ahwa, Saputara and many other villages, several bamboo based cottage industries, cooperative societies, and bamboo products selling co-operative societies exist.

These industries are driven by the scheduled tribes of Gujarat state,the Kotwalia' who are also known as 'Vitolia' or 'Vansfodia'(Vans-Bamboo,Fodia those who break the bamboos) which mean the tribal who break the bamboos.As mentioned earlier traditionally they have been occupied in making big baskets Tokras (baskets), containers etc. from bamboo.

Usually they prefer to stay near the forest region on the bank of the river or water streams where the bamboos are available in plenty.

92

National Institute of Design

These tribes are solely dependant on bamboo industries.

The tribes are entirely dependant on their occupation of bamboo works and basket making.They use bamboo to make different types of products and earn their livelihood.Bamboo plays a significant role in providing employment to kotwalia tribe. The bamboo work provides employment to the entire family with the minimum of investment and due to this, an industry is running in the Dang Districts of Gujarat.

The bamboo industry is useful in tribal areas because it needs minimum amount of investment and provides comparitively maximum amount of returns.

Forest department does not allow the cutting of bamboo, so the tribal sneak into the forests during night to cut and steal bamboo as there are govt. officials and patrol during day.

Either forest dept. provides bamboos to these units or these units import bamboo from North-eastern state. The member/artisans of bamboo working in these units prepare and sell various bamboo items.

Bamboo & Craft The community has been documented to be good in bamboo based craftsmenship. The community is expert in weaving of bamboo mats, baskets and winnowers of different shapes and designs for household use and agri-operations. They also make special type of fishing baskets and traps.

It was also found during primary research that the number of people mastering the weaving is decreasing with each passing day as younger generation is not interested to learn the art because returns are low.

New avenues have opened for the growth of these tribals, to which the community does not have accesses.

From gathering further insights it was found out that there was good demand of naturally degradable, environment friendly ethnic craft based lifestyle products.

It was also realised that there were needs to adopt the skill and modify the products according to the present day demand of urban market.

These products could be anything from decorative utility products, souvenir & gift packaging, mats & blinds, dining table accessories to light and heavy furniture items.

Price positioning of the products was kept cheaper than that of cane and wooden items. The profit margin for community on these products is as high as 40%. This is higher than any traditional source of livelihood.

Different government and non government agencies are currently working towards the upliftment of the tribal craftspeople . At present, the Product Development and Designing Institutes, Agriculture Universities, Research Institutes are working independently in different directions focusing on different aspects of bamboo development. It was also noted that the interlinking the effort of all such institutes and creating a knowledge base in simplified form for the use of the community was required here.

To promote the community oriented work on bamboo, there is a need realised for the improvement on all the three levels of backwards linkages, production and forward linkages of these traditional economies consisting of trades.

The state government, in its annual budget also has granted tax waivers to bamboo and bamboo articles,

It was also realsied during secordary research that the potential buyers for these articles were either upper and upper middle class in urban areas who were looking for innovative products for houses and farm houses and people living in multistory flats.

Big hotels and resorts who sell on rural themes were also realised for assured market.

A low cost sander machine & sensitive vertical press drill prototype developed from locally available compoenents, have made the purchasing of the tools easy for the community and is not only helping in reducing their drudgery,but also towards enhanced livelihoods.

Innovative tools aiding to tribal livelihood development & enhancement Anant has introduced innovative mechanical tools to help bamboo artisans of Dang districts of Gujarats to improve the quality of their products and reduce the drudgery associated with working with bamboo.

The innovator had developed a low cost sander device which is an electrical powered tool that helps reduce the time required to finish bamboo products, typically a painful and time-consuming process.

In close collaboration with BAIF Development Research Foundation, Pune, Anant has developed a number of low cost innovative prototypes, including a bamboo axe and a splitter. The bamboo axe helps in cutting bamboo into four or eight uniform splits in one go. This axe prototype is not only cheaper compared to the traditional axe, but also requires less effort.The bamboo splitter and various other tools developed by Anant helping to mechanize the process of splitting bamboo and finishing,

Bamboo containers made from bamboo node and internode section with sanded and refined surface, which has better finish to appeal towards local touristic market ,thus making the tribals to improve the product finish and enhancing their livelihood option.

Perception of Bamboo as a material In Indian urban markets, products made from bamboo are perceived as cheap, of bad quality,rustic and realated to oriental. There is lowvalue perception of products made from un-constituted bamboo culm also called 'whole-bamboo products'.

Also while doing secondary research I came across the perception that bamboo's reputation of being flawed,cheap and rustic could be mainly attributed to its use in outdoor spaces.

One of the insights shared the perception of bamboo products are somehow connected to far east and can be leveraged as positive association,since it connects asian craftsmanship.

It was also realised that that this positioning could maximise this association against the back drop of growing global interest in alternative therapies, beliefs, religions, natural healthcare traditions Perception of bamboo as a suitable product for use in furniture and flooring but not construction based products was observed in export markets

Perception of bamboo was observed to be uncompetitive for use in wood panels market, especially in high income economies..

Changing Perception

There is also a growing trend towards social & environmental responsibility. People are gravitating towards fair-trade productsand they are produced with the context of social equity since produced by communities and environment preservation since produced in sustainable manner.

The innovators in the sector are working on manipulation techniques and tools which are changing the way the material is perceived or the way the material's perception could be changed with improvements in processing and finishing. These initiatives were seen to be important in changing the old age perception of bamboo as a material to the proposed 'material for the future'.

These perception can be altered by using good preservation techniques, also by creating awareness about bamboo's properties, limitations and usage options among designers, constructor and fabricators.

Manipulating bamboo in different techniques can allow the material to break away from its traditional image,and project the usage of material in a modern context. Manipulation in composite form reducing problems associated with 'natural' bamboo, such as rotting,fungus and humidity related splitting.

Insights

While looking at the domestic bamboo market and especially at the handicrafts market which employed the traditional crafts community, suggested the improvements the craft sector needs to make in order for the industry to progress not only in India but at the global level.

The methods to do this is by providing design inputs and provide product development assistance from the beginning of the value chain ensuring the product matches preference of contemporary markets thus changing the perception of the material usage.

Also through reserch it was realised to improve the design and product development in the handicrafts sector methods like to design minimum acceptable benchmark for production of craft products as well as assisting artisan with process standardisation, can be incorporated to drive the change.

Bamboo in Contemporary Design With the industrial revolution bringing saturation and monotony with mass produced goods which lacked uniqueness and individuality in the way the products were being produced, there has been a revival of products made from natural materials which are essentially made with hands, and in some cases with the help of industrial tools,but there is still the intervention of human touch.

With Bamboo as a natural material in today's context, Bamboo in contemporary market is perceived very positive in terms of being versatile material and having various ways of manipulaing into different contexts. In terms of production,it was realised that its convinient for the indigenious regional communities. In terms of marketing if the products are well made, the notion of being cost effective and aspirations of sustainable lifestyle could be projected in a postive manner.

It was also realised that the contemporary design community which may comprise of designers, researchers, institutions and entrepreneurs were attracted by the possibilites of bamboo and showed great interest towards its potential applications.

and comsumer electrionics companies looking into its innovative applications. Major initiatives in this area use bamboo that has been industrially processed using innovative new technologies.

These new technologies and processes reconstitute bamboo culms into standardised baords and panels,which can be used for multiple innovative applications. There has been a major research in terms of making bamboo composites in the area of product manufacturing and architecture.

Reconstituting bamboo frees its from its 'low quality image' and stereotypical associations of either being cheap, rustic or asian and helping it gain acceptance into mainstream markets, especially in the west.

To understand the contemporary market,further research was done on local artisan, local brands/market and international market to get insights on the current bamboo product market scenario in India.

Contemporary Applications of Bamboo Today's context modern plastic and construction material is displacing bamboo from its historical use and context. From the previous studies into the subject, it showed that the modern bamboo market study showed that there's a new market is emerging in urban areas for handmade utilitarian and decorative objects.

In housing sector, an interest is growing for low cost annexes, restaurants, weekend homes, residential homes.

There's an emerging interest towards exploring modern market that does not require intensive technology, and which needs more Design skills,New craftsmanship & Institutional support.

In this growing market, a transition for traditional bamboo crafts people to the modern bamboo sector can be relatively easy, providing adequate organisation, marketing skills, additional knowledge base, proper policies.

Analysis of Local Craft Market The contemporary local craft market was assessed to show less potential in terms of growth as the products still beared the old aesthetic treatments which have not evolved with time and market forces.

Some products showed potential in terms of the manipulation techniques in terms of aeathetic treatment. The usage of untreated raw material in the making of the products was perceieved to only degrade the perception of the material with time. The usage of excessive decorative details which did not have reference to material properties was observed while doing the study.

The markets at both the locations seemed to have show immense potential towards positioning these handicraft products developed locally.

International bamboo Market The Global Bamboo product market is classified into two major sectorsTraditional Markets, wherein Demand remains strong. This sector includes handicrafts, Bamboo shoots and Chopsticks, wherein margins remain profitable despite slowing growth. On the other hand, certain product lines (e.g. chopsticks) are commoditised and present low growth and low margin opportunities.

Emerging products present the most positive outlook for the industry given the enormous growth potential for such product lines, given their recent emergence on the product scene. These include high value timber replacement products, Bamboo flooring and prefabricated construction. The potential for higher value addition, the existence of higher margins and enhanced profitability and the possibility of changing bamboo’s image as a low quality material.

Bamboo in construction

Bamboo based constructions have been appreciated and implimented into residential,resort and various other applications in terms of architecture and are being successfully used around the globe.

There are three main types of bamboo housing: (i) traditional houses, which use bamboo culms as a primary building material; (ii) traditional bahareque bamboo houses, in which a bamboo frame is plastered with cement or clay; and (iii) modern prefabricated houses made of bamboo laminated boards, veneers and panels.

Experts estimate that over one billion people live in traditional bamboo houses. Its compressive strength is roughly twice the compressive strength of concrete and bamboo has roughly the same tensile strength to weight ratio as steel has. The hollow cross section and solid diaphragms at regular intervals contribute to the strength of the bamboo pole. To get insights on the bamboo based construction some examples were looked at.

Analysis of Contemporary Market The understanding from the market showed the potential in all the market. The contemporary crafts market showed potential towards product diversification, improving the quality standards of production and towards creating better livelihoods through design based interventions. The markets having near source value chains showed potential towards improving the existing products to obtain better price margin.

The understandings generated from the research of local market suggested the potential of bamboo board based products in the urban market and due to the fact that the material was manipulated to visually look and feel like the conventional wood based product and with the structural and visual aspect of the bamboo,it has been observed favourable towards the positive perception of the material. The other negative aspect was the import of these products from China which

showed the domestic competition of the chinese products to the handicrafts product in terms of their market and economic aspect. The brand studies of domestic market showed the potential of natural and bio-degradable material based product's relevance in the contemporary market and how the bamboo handicrafts could be positioned towards these boutique store as a marketing channel and helping towards the development of local economy.

The study of examples in international market showed the positive perception of bamboo towards product development and the material's relevance in the global contemporary market. The insights further gathered also suggested the potential of having collaborations of international brands and studios with craft communities and its potential towards export as well as for domestic market in the backdrop of global views of having sustainable lifestyle and inclination towards handcrafted objects.

Material Standardisation Methods of material standardisation in terms of their quality could be maintained & consistent manufacturing procedures could be explored for efficient use of skills.

In this context, manipulation techniques of splitting,sizing and finishing of basic raw material could thus reduce the drudery and increase the earning potential of individual craftsmen.

Research Needs Systematic research and development activities need to be continuously nourished for the growth and prosperity of the craft activity.

Quality Control Quality of production processes can be enhanced by the introduction of simple jigs and fixtures to standardise size and form in production.

A large part of her work has been in the area of livelihoods, where she has worked with multi-governmental institutions, governments, NGOs, SMEs and communities in Europe, Asia and Africa. She has also authored a book, Bamboo: From Green Design to Sustainable Design, from which good insights were derived towards livelihood development and altering the perception of the material through design inteventions.

Negative perception in market In urban markets,products made of bamboo perceieved as cheap & of bad quality rustic and related to orient.

Important to understand why products made from un-reconstituted bamboo also called 'whole-bamboo culm' also called 'whole-bamboo products' are perceived to have low value.

Its equally important to position them to maximize positive perceptions associated with them.

Design for Sustainability Bamboo's reputation of being CHEAP, FLAWED and rustic can be mainly attributed to its use in outdoor spaces.

Can change the perceptions by using good preservation techniques, also by creating awareness about bamboo's properties,limitations and usage options among designers,constructors and fabricators.

Even though there is fast interest in designing and developing products and services within emerging markets (design for the base of the pyramid) many initiatives focus on scale of industrial production by multinational corporations are ignoring the skills and resources available locally on a community scale.

Indigeneous knowledge as a design input during the innovation process can be looked into.

This knowledge is viewed by the designer in the context of sustainability and factored into innovation in collaboration with the craftsperson, thereby maximizing the skills and knowledge each brings in this innovation process.

Using bamboo in composite form allows it to break away from its traditional image, reducing problems associated with 'natural' bamboo. such as rotting, fungus and humidity related splitting.

Tendency in design world to focus on 'human-centric' design, where the human is often seen only as an end user.

Breaks away from the limitations of the natural bamboo shape.

Composites have been crticised as being unsustainable since its difficult to separate the core materials for recycling and disposal.

Whole bamboo is round and non-standardised making joinary and fabrication easier.

Several different components can be made by splitting or crosscutting the bamboo culm. Thes can be laid out together in various arrangements and in different ways to form a surface.

The crossections of bamboo, can be circular if cut straight, or elliptical if cut diagonal.

'The design' is seen only as serving the consumer and companies that bring products into the market.

The other 'human, social, cultural' part of the value chain is often overlooked.

Design can and should play an essential role in developing the local skills and resource based products, and in facilitating dialogue among the stakeholder,enabling the development of 'real' sustainable products.

Bamboo and combination material Bamboo is natural and eco-friendly material,miche in segment. When combined with natural material such as shell, bone, natural fibre and teracotta, reinforces the product's image being natural 'handcrafted' and eco-friendly.

Traditional economies consist of trades, bamboo craftspeople coexist with weavers, potters leveraging two crafts in a reasonable proximity can lead to unique products.

Since both materials are natural, dealing with issue at the end of the product lives- sucha s bio- degradability is quite simple.

Bamboo as a natural material is perceieved being only used for handicrafts. Fit 'Pure' bmboo product into similar aesthetic bracket'-call for cutting technology to reconstitute bamboo.

Using 'components' made from industrial materials allow products to have feature and properties that would be compromised if the product had been 100% bamboo.

Buyers have seen its traditional applications like baskets, hightech composite applications as bamboo board,bamboo viscose, now being evaluvated in terms of actual contribution to sustainability, preservation to environment.

Usage of recycled or repurposed industrial wasteenhances the sustainabiltiy quotient spreading the culture of sustainability.

Combining bamboo with industrial material suchas glass, metal allow the resulting products to take on a modern/urban contemporary mass market aesthetic than if it were only with bamboo.

material. At CIBART, the function of the setup is to aid in rapid production of bamboo products while aiming at the scale and quantity without compromising the quality aspect.The organisations incorporates electrical devices that reduces the product development time greatly which would have been a challenge with manual handheld impliments otherwise.

The bamboo machines and tools utilised at the center, can do most of the task that increases the productivity and decreases the production time and are used by both the men as well as women.

The machines are industry standard and very efficiently lets the craftspeople cut, lathe, remove the knots, drill,grind and sand thus manipulating the material efficiently and thus becoming stages in production.

Outer Node Removing Machine The Knot removing machine as the name suggests gets utilised for removing the knots as the knot protion is difficult to process using manual impliments.The device is basically is bench exposing a rotating blade connected via a rubberbelt which is attached to a powerful motor that rotates the blade.

The craftsperson rests the bamboo pole on the flat bench which is adjecent to the blade and moves the poles in circular motion against the balde so as to grind the portion thus making the knot portion almost even.This method thus is followed by handheld grinding tool as to achieve a greater level of finish.

Round Push Saw The round push saw is a time saving tool which conviniently lets the craftspeople cross cut the length of pole desired by pushing the pole against the saw kept on a hydraulic bench. This blade used for cutting the poles is specially designed to cut the hard exterior fibres of bamboo.

Pneumatic Punch Machine The pneumatic punch machine is used for making photoframes.The device is connected to an air compressor which forces a staple pin to get punched at high pressure on bamboo slats kept at 45 degree angle, resulting in locking of the pieces together.

This method is then repeated on all four joints and that creates a frame which can be utilised to showcases photographs .

The drill is observed to be utilised mostly for creating cavity into solid bamboo poles while acting as a female joint to the joinary created for locking two members for structural support.

The CNC routing machine at CIBART utilised bamboo laminated boards as a surface to carve or cut various shapes when clamped on to the platform. At the workshop a lot of products are made with CNC manipulation, from wall clocks, table surfaces, trays or a no. of products.

Sanding Machine The sander machine is used for radii manipulation as wel as treating the edges of product being developed at the workshop. This machine acts as a stable tool for smoothening the edges of objects which otherwises is achieved through grinder powertool.

The machine uses electricity to run the powerful motor that rotates the sander belt of the sander machine and upon keeping the object on the surface,removes the material due to friction.

Round Saw Machine The round saw machine manufactured by bosch is hydraulic saw that cuts the bamboo poles in various angles and orientation due to variable adjustment arms and a strong blade specifically designed to cut the strong fibre structure of bamboo in the crosssctional orientation. The machine reduces the efforts of cutting the poles which is a time consuming activity that otherwise puts a lot of stress on holding the bamboo culm and cutting it by using a haxsaw.

Power tools Power tools are various types of tools and mechanical devices that operate when they are initiated by an external power source. This could generally be electricity, air or pneumatics. Power tools include many types of tools from hand held machine drills to hydraulic presses and pneumatic tools.

In the context of CIBART, the power tools used extensively were the Hand Drill and the Angle Grinder. Both the tools were used for various purposes in terms of manipulation of the material.

Hand drill

Hot air gun

The hand held drill tool is utilised in either creating cavity for dovel joinery or for interlocking the joints for better support.

This tool is essentially used for bending bamboo splits. The temprature generated to 600 degrees is eduquate to weaken the fibres thus making the material bend.

Grinding

Manual Bamboo Slicer

One of the handheld tools utilised at the workshop is Grinder that is used for removing knot bulges and making the bamboo poles smooth enough to be used for furnitures and other products.

The tools happens to be a very useful impliment for the craftspeople for finishing the bamboo poles as well as cutting the poles as the tools heads could be changed from grinder to cutter.

The bamboo slicer is a device that evenly slices the bamboo splits to create slivers to be used for creating baskets or for making prouducts with slivers.

The mechanism involves spliting the bamboo as the first step and making it of a feet length.After splitting and cutting the slat,its fed into the device and while holding the handle which has a blade underneath the moving section, the section is moved back and froth, which evenly splits the slat resulting in multiple splits vended under the device.

Handheld impliments/tools Hammer

Hacksaw

The hammer is the most rudemnetry tool used for multiple appications while developing the products. In bamboo applications its used for applying pressure to either support in splitting the material or making the joints tighter.

The hexsaw tool is used extensively at CIBART to cut the bamboo poles of desired length. Its interesting to observe the way the tribals use the grip of their hands and feet on a hammer as a platform and cut the pole with hexsaw.

Dau

Glue Container

Dau is a universal tool in the lives of Kotwalia community.

The tools is used for multiple purposes while processing and manipulating the material. The tool is used for chopping the bamboo poles initially and later is again utilised for splitting the material as well as creating slivers.

This is make do tool comprising of a knot section of bamboo and bamboo sticks which is used for applying the glue to the joineries as well as for interlocking of joineries in which the bamboo culm is drilled and the sticks are dipped in the knot container filled with adhesive and applied to the required location.

Chisel Tool

Miscelleneous Tools Clamps

Long Vice

These devices hold two or more surfaces in place but at the workshop context is utilised for various purposes i.e gluing, bendng or radii manipulation of the material. These come in two types either as G or C clamp and used according to the purpose of usage.

The device has a long bar along which a flat element shifts which is fixed to any element that need to be held for the purpose of fixing,gluing or fastening of one member to another.In the workshop's context it is utilised to grip the bamboo poles which are either being glued, stuck or held for the purpose of joining, holding or gluing.

Phase 1 Procuring raw material

The procurement of the material happens from Assam and is brought to the center by a truck and at a time deliver 400-600 poles of majorly Bambusa Bamboo species.

There are two species that are transported from assam to Vansda and the other center at Waghai which are Dendrocalamus strictus & bamboosa bamboo.

The bamboos are dropped from the truck and piled in front of the center and kept for grading. The first process is grading the bamboo after it is bought from the market / farmer Grading is sorting out bamboo on the basis of characteristics important for structural utilization as under:

• • • • • • •

Diameter and length of culm Taper of culm Straightness of culm Inter nodal length Wall thickness Density and strength Durability and seasoning

161

Phase 2 Treatment of the material Drilling at knots

Treatment in chamber

After grading the next stage is treatment of the material where the sorted bamboo poles procured are drilled and then taken through series of steps to treat the material, Once graded and sorted, the poles are treated with chemicals so that they are not attacked by borers and other insects, climate and fungus.

162

National Institute of Design

Graduation Project Doc.

The bamboo poles after drilled at all the nodes are loaded in the vaccum chamber for essentially removing the starch conent in bamboo. The treatment involves putting high pressurised chemical solution to seep into the material fed in the chamber.

The chemical is a boric-borax solution that enters all the pores through capillary action when the liquid is passed through it under vacuum in this treatment plant.

The chemical essentially replaces all the organic matter that is prone to attack and so the bamboo becomes almost like a plastic material by the end of treatment.

The treatment takes about 30-45 min and by the end of it the sap is completely replaced by the chemical solution and thus is a step closer towards longibility and durability.

Drying

Storing

After drying the poles for a certain period of time, the poles are graded and stacked according to their usage and The most common way to dry bamboo for commercial purposes is "air drying".

Once the bamboo poles are harvested and chemically treated, all poles should be stacked and stored under cover.

The bamboo should be only be used atleast after 6 weeks of felling and 15 days of drying after the treatment process.

After the treatment, the next step is to dry the poles under the shed for a period of 15 days, till the solution dries completely and makes the poles usable as a treated material for further applications.

Phase 3 Processing/ Product Development Bamboo selection

The next phase of product development involves skinning, removing knots / sanding, bending/ straightening with burners as bamboo when heated bends easily as the fibres become ductile and retains shape on cooling!

Primary & Secondary manipulation

Cutting

The storage of bamboo is accessed after the bamboo poles have been dried completely and as per the use, is selected on the basis of -

Purpose of usage

Condition of culm

*Cracks *Crookedness *Decoloration

After the selection of the required bamboo poles, the material is either cut with a hacksaw tool near the storage or carried in the other workshop, where the cutting can heppen either with mitre saw or bench press round saw.

Bamboo Heat bending

The poles either before or after the cutting, are first taken to a shed besides the workshop where the crookedness of bamboo is corrected through the heat bending process.

The apparatus used at the organisation included a frame (in this case a chopped tree) which has a drilled cavity and is used to hold the bamboo in place and at the contact point, physical pressure is applied to the pole in order to correct the deviation.

In order to straighten the material,

National Institute of Design

Graduation Project Doc.

Manual Processing

Primary manipulation is done using manual tool and depending on the situation of usage. There can be parameters defining their usage of such impliments from availability of electricity, machines if occupied or availability of tool, ease and comfort of use.

Machine Processing

The machines ease the processing of the material in the product development phase, thus increasing the productivity and reducing the manufacturing time of the products.

Removing knot swellings

The grinding tool was observed to be used both by the men and the women craftsperson at the organisation. The tool has an abresive surface which rotates and is used on the length of poles to make it uniform.

The material is rotated intuitively,so as to remove the swellings and make the surface even for further product development.

The next step is to remove the knot which either can be done using knot removing machine or powered grinding tool. The removal of knots gives the surface a much better and uniform finish which may be difficult to process using manual impliments.

The craftsperson rests the bamboo pole on the flat bench which is adjecent to the blade and moves the poles in circular motion against the balde so as to grind the portion thus making the knot portion almost even.This method thus is followed by handheld grinding tool as to achieve a greater level of finish.

Joinary Construction

Slat making

The next stage is to manipulate the material according to the use and understand the joinery construction which required the use of both primary and secondary manipulation.

The product process of developing a chair was documented to understand the flow of production processess and the sensitivities required to work with the material.

Joinary Construction

In the majority of products seen at the organisation, the use of solid bamboo with dovel joinary construction was seen commonly. This required the use of removing some material by diagonally making a champhor to create a male joint and creating a cavity in the other member to create a female joint.

168

National Institute of Design

Graduation Project Doc.

Cutting

Drilling

Male joint

The joinary process starts by cutting the lengths of solid bamboo required for the specific design and making a pencil marking on the surface which goes diagonally and vertical to create a socket form. The intention of creating a diagonal champhor is to resolve the form when the male joinary in inserted into the female joinary.

Female joint

To cut and make a champhor, hacksaw tool is used on the area being marked. The craftspeople mostly are seen working on the floor as it is convenient for them to do material processing activites. To cut the material, vices or clamps were not seen to be used. Rather the method to hold the material at place was to put the pole on a hammer on the floor by making grip with hands and using the hacksaw diagonally to remove the material just at the points of marking .

The protuding joint is later shaved to define a radii in order to ger accomodated into the cavity perfectly.

After making the male joint, the female joint is created by first marking the area where the dovel needs to be inserted. The marking is done by using a pencil and centimeter scale and a 8mm drill bit fixed on the upright sensitive drill press machine.

Joining To permanently fix the dovels and make the structure rigid for its longivity of usage, glue is applied to all the joinaries and at the contact point. The adhesive used at the organisation is Bond-tite due to its local availability,its strength and being economic than other competing brands, thus proving value for money at the organisational context.

Applying glue by using mixing two parts of the adhesive in a knot made as a container using a bamboo stick.

Clamping

To make the joint strong and also look for angular/structual error, long vices are used at the time of gluing the members together. The vices can be adjusted to the length and is used as a frame to put all the joints together to check for orientation correction.

170

National Institute of Design

Graduation Project Doc.

Inserting Kheela To lock the joints for enhancing the strength, bamboo sticks are utilised . Initially the contact points of joint is drilled, and later the stick which has already being dipped in adhesive solution is inserted into the drilled cavity and is hammer or pushed inside using a flat side of chisel.

The protuding part of the stick is then broken at the tip near to the surface using the chisel . This adds to the strength and is now structurally strong for its use in multiple applications.

Heat bending Depending on the type of construction and language for the furniture, heat bending is done to different member either for the pupose of enhancing the ergonomic or for adding element of interest to the minimal language of furniture seen at the organisation.

The dovels for back support or the slats of the seating are bent by heat bending either by hot airgun or the burner rod.

Phase 4 Finishing Grinding

Sanding

Varnishing

The last stage of all the product is to get a certain surface quality, on the basis of which the product would be perceieved, interacted and sold with.

The finishing is an essential part after the product takes its shape in the unit processes.

172

National Institute of Design

Graduation Project Doc.

To enhance the surface of the material,the products are finsihed by using sandpaper of hard and later soft grade. The burn spots and ebrupt edges are made even with the use of sandpaper as well as grinding tool.

To correct radii on the surface, chisel tool is utilised.

The surface is scraped evenly for post processing.

Sumedh Sonare

Expl. Bamboo products for spaces

173

Varnishing

The last stage after the product is made,is of finishing.

The process is done to combine the protective and decorative function of the unique material. This process ensures the Wood varnishes provide a very good and durable finish that seals in the moisture in your bamboo. The only possible problems you may experience will be cracking or peeling.

The finished coat provides the ability to resist a great range of external and internal stresses where physical chemical or biological must stay stable in wider range of temp. conditions.

Suitable finishing is done to the material in terms of grinding and sanding to make all the surface even,priorto the application of the coating material.

Varnishes are available in oil based and water based finishes, from satin smooth to shiny gloss finishes.

Varnishes are applied using air brush which uses an air compressor to create pressure thus creating a jet of spray which spreads evenly on the surface.

Understandings from material manipulation Through all the stages from getting the material to the finished products, there was a lot of understanding generated towards the various aspects of production processes invovled that led from a raw material to its intended form that served a function. The various stages were found to be essential aspects of utilising the various tools and techniques for the manipulation of the raw material.

It also informed about the drudgery the craftspeople generally face outside the organisation who do not have access to the machine and spent a lot of time in processing the material thus not meeting the market demands and expectations, as at the workshop these machines have been aiding in the efficiency towards product development and enhancement of the physical perception of the material. All the various tools possessing different functions, had been observed and understood to generate understanding of their usage and the various context under which they were operated.

It also validated the research analysis of the challenges the crafts community has been facing from procurement of the material towards the manipulation and finishing of the products.

Amrat Bhai

Ramesh bhai comes from Ganpur village and has been part of organisation for the last five years.

He is a master crafsperson, and has been training tribals who come to the organisation since a lot of years and also is asked to give workshops and share the traditional ways of manipulation of the material.

He has been doing this since early ages and started picking up the interlacing techniques by observing his father weaving baskets and traditional utility objects. He has a bike for transportation and comes to the workshop with his wife who is a also an artisan at the organisation.

His roles at the organisation is to train and supervise the production flow and intervenes when required to check for quality control, product finishing. His economic conditions has improved since the organisation has employed him and gives work and monthly wages.

Prakash bhai has a wife, who comes along with him to the factory and is also an artisan. Has 2 acres of land and does farming. Has a brother who looks after the farms thus having parallel source of income. His skin is light coloured and light coloured eyes suggesting, he’s of a different origin as his father narrated him the story of how they was initially outsider and came to Gujarat for business purpose.

He is Kotwalia by tribe, but majority of tribals have dark skin. Some of the tribes have similarities, suggestive of African origin. Prakash is good with his skills and analytical ability and can understand form and proportions well. He is sensitive and humble to take up any tasks at the organisation willingly and had shown extensive interest towards new ways of manipulating and exploring the material.He has a motorcycle for communting to his village 10 kms away. He shared that his economic situation has been better since he has joined the organisation with his wife as both together get 5k thus 10,000 out of which major expenses are on fuel and food.

Amrat bhai is a father of three children and got married at a very early age of 16 when his wife was only thirteen. He is another mastercraftsperson as he works on bamboo structures, large furntitures and also products.

Apart from working at the organisation, he is a musician and plays on drum pads during festive occasions and collaborates with other fellow people from the community and gives his parallel livelihood support to take care of his childeren.

He comes to the organsiation along with his wife who is also another craftsperson working on mostly furniture and products.

He shared that his economic situation is good as he and his wife are generating income along with their childern who are also taking up parallel jobs and also makes money through playing instument, which gets him a good livelihood to secure his family.

Visit to Saputara The organisation CIBART has rented a space from a women self help group NGO, at Saputara which is located 70 kms from Vansda in Gujarat. The space is utilised as a store to sell bamboo products developed at CIBART and is established,keeping in touristic market as context.

While, doing field study, Mr. Bharat Parekh who is the operations director at the organisation, shared about the presence of such a store and shared the possibility to convert it into a cafeteria space.

The space was visited later to look at the area and understand the spatial context of the shop with respect to the location it was based on. The objective was to seek for opportunites, if there was possibility to base the product development context within the store at saputara.

Saputara is located in the state of Gujarat. It lies on the Maharashtra-Gujarat border and is easily accessible by road from cities Mumbai and Ahmedabad.It is a hill station and is located on a plateau in the Dang forest area of Western Ghats (Sahyadri) range at an altitude of about 900 metres.

Saputara has been developed as a planned hill resort with amenities like hotels, parks, swimming pools, boat club, theaters, ropeways and a museum which have been positioned to cater to tourists transiting the hill station.

Field Study The first impression of saputara was very contrasting to the other places seen in Gujarat. Having being visited during monsoons and also being at higher altitude, had a pleasant weather and fresh air.

The area was seen surrounded by a great vegitation and the hill station seemed to have a lot of interesting spaces to engage with.

It is 172 kilometres from Surat and 250 km from Mumbai. The Maharashtra state border is 4 km from Saputara. Due to this fact that it's Gujarat only hill station and also its connectivity between the two states, the area is frequented by a large no. of tourists who do a stop over at the hill statiob for a few days, spent some time and then move to the other state.

There was also a water body which was entered through a mini amusement zone created as a touristic attraction. The lake could be accessed through rented boats and was observed to attracted a lot of visitors. The zone was surrounded with food stalls and novelty items store to cater to the visitors .

Outer Side of the Shop

Store Entry Less visibility of the entrance due to the narrow access area door either seen closed or open.

Did not have any sign of it being an entry to the shop thus creating spatial ambiguity.

Branding Efforts The flex placed in front of the stall, was inappropriately positioned and did not create a strong recall value for visitors to identify either the stall or the store.

A flex banner placed on the grill depicting name of the organisation in a different identity and bearing images of the products in a chaotic catalog format.The placement on the grill also blocking the view of products kept inside the room.

As the first impression of the space, the shop was no where to be visible and just had a tea stall with tin roof and was supported by metal tubes for support. The space was covered by foliages and to much of a surprise, did not have any traces of bamboo plantation.

In terms of the visitors visiting the space, it was mostly observed to be frequented by families,couples and a group of friends who had come in private vehicles or by public transport to the hill station.

Below, the people were observed to be sitting on plastic furniture, where as the the functional bamboo products in terms of furniture were kept on for display in the enclosed space. This aspect was creating a much disturbance in the positioning of the shop in the space.

The space outside was managed by a women who was a resident of Sapurara but was from Maharashtra, and prepared a puffed rice dish called 'Poha' and mint tea for the visitors. The tea was served in either a metal cup or shot plastic containers and the poha was being served on ss plates.

The shop did not seem to have a good sign board in place for visitors to identify either the stall or the shop which was behind the stall.

Above, the side view of the shop shows chaos in the space and on the extreme right-hand side is the door, which is the only entrance to the store.

The grill besides the door has a flex banner on it, and depicted the products as a catalog of objects which seemed disinteresting to the visitors who were busy in having conversations over tea and poha.

Interiors of the shop Once the space was accessed from the entry point, the first thing to observe were the series of products which had the same mundane colour harmony from the natural tint of yellow of the bamboo fibres which created a contrast between the chaotic ceiling beam structures with a lot of linear lines intersecting and thus created visual disturbance. The amount of light coming from the windows on the left, was uncontrolled as there was no presence of light diffusing elements. The wooden slats being broken at places, left the space unsecured and potential for thefts.

Immediate spatial understandings Unsecure Unmanaged light Ambiguity in spatial elements Visual disturbance within structural elements 188

Understanding spatial elements The space had a collection of products made mostly from solid bamboo of dendro calamus species. The product catagories noticed were mostly consistling of either Furniture, Lighting and Decor objects. The products were arranged in close proximity to the wall and the table at the center created defined a walkway around the space. The products in the space were kept with the context of a living room space as conveyed from the mentor who

had initially proposed the idea for the space. The wall partition created another space which held a bed made from bamboo.

Even though the products were made to target the tourist market, the products kept in the space were morover products being targeted for home utility and home space, the products created questions regarding the sellability factors with the criteria of price postioning, portability and packaging.

Good flow in terms of wayfinding The curation of products could have been better The lighting was not consistent to bring focus onto the products Monotony in terms of the colour due to the natural colour of the material of the products

Visitor Interaction The visitors who came to the store were interacting with the products by touching, picking, sitting and moving the objects around to get a tactile perception of the product ranges. The visitors who came to the store, were of all age groups and were participating equally in terms of interacting with the spatial elements.

The spatial interactions of the visitors were mostly observed towards tactile feeling of the surface, holding of the products, checking the product from different angles, lifting to check for the weight and left the space without much enquiry as the space was either not seen to be moderated or managed by the women who ran the chai stall, who was given the task to run the space and do the job of selling and managing the profits shared with her in some percentage.

The space lacked information or information system in terms of the propogation of the benefits of using the material thus helping in promotion of the material usage and also the concept of 'Fair Trade' with the association of tribals who helped in the development of the products.

The only branding tounhpoint was observed on the tags which either were present or not and created an ambiguity within the interaction of the visitors with the lady who ran the store in terms of the price of the products.

Understandings of the overall space The other aspect was to understand the curation of products in the space. The space had moreover, three product types; Decor, Furniture and Lighting. The products,mostly being made with solid bamboo had a sense of monotony as it was being interpretted more as cane and showed a very little form aspect of bamboo.

The products mostly utilised solid bamboo and if talking about the form aspect and proportion were quite large in scale for the visiting touristic market. The portable product range included wall clocks, water fountain, organisers, and utility racks which seemed apt towards the touristic market, who could easily buy and carry the products with them. The product language was observed to have excessive preoccupation with decorative details which probably did not have any reference to the material properties or traditional forms and could also result in the degeneration in the aesthetic, structural quality standards of these

products. These objects were either rhizome carvings or lathe turned bamboo units stuck on a frame that served as utensil organiser. The other products were laminated surfaces in form of wall clocks and smartphone holder which were relevant to the market requirement but the form language was in stark contrast to the product language of other products.

Product range in terms of furniture not addressed well in terms of positioning whether, they are supposed to bought at the store or, if an order was placed, how was the transportation cost being managed by the organisation. The scale of the form of the products was quite large in proportion and thus did not fit in the portability criteria for the tourist market as the visitors who came to the space were mostly coming to the hill station in vehicles which barely had space for extra storage space for such products to be carried.

There was chaotic arrangment of objects all over the

place. The decor objects had intentional rustic feel which was questioned, whether it appealed to the touristic market. Products in terms of decor and utility were either lighting or novelty objects.

The majority of products have gloss melamyne finish on the surface, making the surface look plastic. Even though the gloss finish sealed the surface against chemical and biological attacks and provided a good finish, it excluded the natural feel and shine of the authentic bamboo material.

The prices ranged from 200rs.for a simple phone holder to 20,000 rs for bed/ dressing table and was quite a large proposition towards the market of tourist nature which would have more affinity towards easily purchasable and portable products without burning a hole in the price sensitive Indian tourist market.

Deriving inferences From observing the space and looking at the store setup at the hill station which attracted a great no. of tourists from all walks of life, it created a interesting perspective towards the understanding of issues from design point of view. The issues ranged from product contextualisation, the visual disharmony in spatial elements, the experiencial aspect and tangibility to start with.

The issues were then analysed to create an inference to the important aspects mentioned.

The only natural light source were from opening from the front and one from a side which put less emphasis on the products and illuminated the products laterally.

The artificial light sources were LED based white flood lights, over-exposing the space from both front and back position in the space thus increasing the stress on eyes to focus on the objects.

The elements of the space w.r.t to the store had a lot of visually disturbing spatial interaction as the supporting beams possessed rods in different angles which intersected with beams at the back.

The bamboo products which were part of the space also created a not so interesting visual drama due to the cylinderical form language which was not cohasive with the other spatial elements.

The was absence of cohasivity within the elements and as there was not considerate attention towards the various aspects of putting up a themed concept store, it failed to create a memorable experience.

The wall at the back bearing a semcircular cavity created a stark contrast with the products as well as the spatial elements.

The experiential aspect of the chai stall and seating was mostly limited to the good mint tea and less with the spatial elements, The exclusion of bamboo furniture from the store and usage of plastic seating also was a crucial factor of not providing the experience of the actual usage of furniture in practical context.

Dimensions/ Proportions

Pricing

Tactility

The scale of the product range in furniture was large, which negated the portability factor,thus making the products less-likely to be brought in store and also towards e-commerce due to the rigid and fixed structural construction of the products.

The weight was also a negative factor in terms of the furniture as the products were mostly heavy due to the usage of solid bamboo.

The product ranges were priced between 200 Rs. or the smallest product to 20,000 Rs. for the furniture which were key factors for the products to be sold at the store.

The ratio of the portable products to the furniture was less which was also a major down point for the purchasing of products at the store.

The products curated at the store were produced well from the craftspeople have good surface transitions at the joineries and structure. The products in terms of usage had a good tactile feel but the gloss melamyne finish rendered the products plastic like finish, thus changing the natural finish perception of the material.

Contextual Analysis Product contextualisation, the visual disharmony in spatial elements, the experiencial aspect and tangibility were the key issues highlighted from the inferences to start with. The issues were then analysed to create an inference to the important aspects mentioned.

It was shared by the Industrial mentor during the time at visiting the store, that the chai stall had the potential to be converted into a cafeteria or a restaurant space which could invite the visitors into it and engage them by serving hot or cold beverages and some local food contextual to the setting at the hill station.

This served as a good insight and showed an opportunity to relink the observations for an idea for a potential space which could be perceieved towards a platform for product development initiatives.

The outer space could serve as an entry point for tourists to engage with products which could be specifically developed with the context and utility for the cafeteria space,around which a product based experience could be created. This way, the visitors would get opportunity to engage and interact with the product and invariably with the material with the embodiment of craft based production, livelihood support, fair trade, ecological relevance & new perspective towards the material .

Also serve as a platform to change one of the perceptions related to bamboo crafts as "tired and old fashioned" from the language of products.

To understand the links and meaningful connections, an Idea and service map was created to define the parameters more further to map opportunities within the space and the holistic aspects to be worked on.

Restaurent Space context After defining the spatial elements as products for cafeteria or restaurant space, it was important to know what these spaces were and what were the key aspects of the space, which needed to be understood for having a better understanding towards context development.

It was understood through secondary research that restaurant/cafeteria is a business which prepares and serves food and drinks to customers in exchange for money. Meals are generally served and eaten on the premises, but many restaurants also offer take-out and food delivery services, and some only offer take-out and delivery.

Restaurants can differ greatly in appearance and their offerings, including a wide variety of cuisines and service models ranging from inexpensive fast food restaurants and cafeterias to mid-priced family restaurants, to high-priced luxury establishments.

Bamboo Material

Explorations The material explorations had started simultaneously with the research so as to understand the material, its properties while I was deriving insights about the community and the ways with which the community utilises the material in their lives and lifestyle.

The essential aspect was to either explore the material hands on or observe the craftspeople manipulating the material so as to understand the various industrial processes which could later take direction in terms of product development.

Bamboo Material Exploration Initial Material Explorations The initial explorations were initiated inorder to get an understanding of, in how many ways, the material can be manipulated. The initial explorations were done with simultaneous development of products which were suggested by the mentor at CIBART. The idea of taking up the task of working on the products simultaneously with material exploration was to understand the material at the earliest, so as to find directions which later could take shape in terms of potential design languages for product development.

During this process, the engagement and interaction of craftspeople, staff, the machines and the material was observed so as to understand the various aspects of the project and product development criterias.

The initial explorations provided a great perspective towards the various prossibilites with the material, and the various ways of manipulation provided much greater insights about the material. The application of the understandings generated at the institute from various modules, informed the development and evolution of the explorations, and building up of the context during this stage.

Material Exploration Methodology The material was extensively explored at the organisation with the artisans while understanding the various parameters and sensitivites towards the manipulation and was informed by the learning from the institute and various modules.

The material was initially observed from artisans methods of manipulation and later was attempted with tools,machines and techniques while keeping those methods as well as the understandings developed at the institute, from various modules in mind.

This led to the exploration of various directions for surface and form development/ manipulation, where the intention was to seek for the best methods which could shape into potential product development directions.

Split based explorations Bamboo splits are longitudinal sections of a bamboo pole (culm). Splits are the full thickness of the culm wall and have the green outer layer still attached. The splits are the most easy to process parts of the internode which just requires a tool and force to basically divide the crossesction longitudinally and is easier towards the internode and less towards the nodes.

The purposes of creating splits in various width were towards creating seating surfaces, handles, lampshade structures and had various other possibilies,given the varieties of longitudinal physical form structures.

At the organisation these splits in various were majorly used for the purposes of interlocking for joinary reinforcement,also as a medium of gluing and when being processed, were a medium of community gathering.

Looking at the physical structure of the splits and their aesthetic quality of being visually and physically light,and also having the outer and the inner skin exposed simultaneously, induced a trigger to explore this aspect in a newer manner.

The manipulation in these sticks in either rectangular or round form was explored to seek for potential direction without being bounded to just the cafeteria context, thus keeping the explorations open ended.

The task was also to seek for understanding of how the split manipulation also brought upon a sense of community feeling and by the understandings of Form and Culture module, how the processing of a material in this manner could be seen from various perspectives.

Radial Split based exploration At the organisation these sticks or slats were the easiest to process with rudimentry tools.

Only in order to provide uniformity, the usage of planers and sander machine was done.

The physical form aspect was utilised and explored to seek for potential directions.

Rounded radial split based explorations The splits, after being processed by vertical splitting were rounded in cylinderical form by the removal of material using a knife by the craftspeople. These sticks being abudently available at the organisation, were explored throughly due to its form structure and aesthetic quality.

Round split based explorations The bamboo radial splits in the form of nails are essential part of all furniture’s or the various bamboo products and structure developed

by CIBART. The community indigenously crafts these nails and it serves it purpose, either for filling the holes, left after bamboo treatment or for making the joineries stiff. Splitting the bamboo into sections, equal to the wall thickness of the culm, creates the nails.

The vertical sections are essentially rectangular with a slight convex and concave curve from top and bottom. The vertical sections are later chiseled using a knife (tool) crafted from hacksaw blade by sharpening the opposite end of the tool to create a sharp edge and is later fixed on to a bamboo handle and tied to be used as sharpening tool. The vertical sections, which were essentially convex and concave, are rounded using knife in few minutes.

Moreover these can be made in a large nos. within a short span of time by any artisan without major specialization as per the skills.

As for the properties, these nails can be bent to required shapes by heat bending to temperatures ranging between 400-600. When heated the fibers start loosing their rigidity and with appropriate pressure, can be bent to required curve and angle to the certain extent. This property makes it moldable to various shapes and thus was potential in terms of exploration.

From form perspective, the nails are cylindrical in structure and look like thin sticks and may have diverse applications if used just as form.

The nails are not necessarily absolutely 180 degree linear. The nails show slight bending, as this was an observation.

The observation was that during splitting it at exact marking, the fibers splitting showed a slight deviation. Due to this factor, the nails may or may not be absolute linear, which gives the form of the nails an organic visual identity.

Process to make bamboo stick/nail

Selecting internode The first step was to take an internodal length by crosscutting both the sides having nodes. The next step was observed to split it vertically using a knife,dau or a splitter device.The device has blades distributed axially at defined angles and is fixed on a stiff metal frame.

The material was kept vertically and hit with another piece of bamboo.

Further split into sticks The slats are again taken on the splitter or by using a knife, split into even longitudinal parts.

Splitting the material The vertical impact splits the cylinderical form of the material into slats of rectangular shape, which are then taken for further splitting.

Making sticks The sticks are further processed with the help of knife and the convex and concave radii on both the sides are removed by moving the knife in to-fro motion.

This process was done is groups. The craftspeople would sit with the semi processed sticks in the open and shave the sticks while engaging in social gathering. The rhythmic movement of the shaving,went along well with the engagement of craftspeople in conversations together.

Initial Exploration While working at the workshop, these nails were found at every part and floor of the workshop, as the nails were made in bulk for interlocking and glue application purposes.

Looking at the physical structure of the nails and a portion of outskin,exposing the natural tint of mature bamboo,gave the insight to join and observe the section in series.

Gathering

Joining with glue

The sticks from different culms held together give the insights to the colour variations the outer skin possessed.The observed phenomenon was the variation in colour tones and together there was a harmony.

The next stage was to join the pieces together in an intereting linear form and explore the product context with the sticks.

The sticks were later joined together with flex kwik (quick binding) adhesive while keeping the tonal variation of outer skin. While intuitively joining the pieces together, a form was manifesting as the sticks from one side were kept aligned.

The form with the overall gradiation looked interesting and showed potential towards creating interesting forms with utilitarian context.

223

Further Explorations The next stage was to explore the bending properties of bamboo, to seek for possibilities lying in any of the context defined in the brief. For this exploration, sticks were obtained and checked for equal length. With a brief experience with bamboo heat bending, it was first realised to dip the bamboo in water so as to make the fibre structure flex when heat would be applied.

224

Wetting

Heat Bending

The sticks were dipped in a bamboo culm filled with water and kept for about 5 minutes.

The next step was to clamp the stick and heat the surface to explore the bending property of the material for which a hot air gun was utilised and the stick was clamped to a baby vice. The stick was applied pressure simultanously while applying heat to the outerskin and rapidly moving the hot air gun.The heat from the gun after reaching 600 degrees let the bamboo fibres flex which were held firmly till the temp. on the surface cooled down. This resulted in the bending of the stick from a certain distance and at the point where the stick was clamped. Looking at this phenomenon, it was intuitively realised to create a form by arranging them axially together and then make inferences from.

National Institute of Design

Graduation Project Doc.

Arranging on frame

Completed arrangement

To arrange the sticks axially, it was realised to create a frame on which the sticks could be arranged. The first thought was to paste them like the previous mockup but due to the limited usrface area, it was realised to create a concave radii surface on the sticks could be arranged. To create a frame, a bamboo crosscut ring was incorporated. A chisel tool with radii was used to split the material to give a groove on which the sticks could be arranged. After chiselling the entire piece, the sticks were radially pasted. The resulted form was interesting visually and showed potential towards contextualizing in form of lighting.

With light The form was checked with a torch on top, which distributed the light evenly through the negative spaces and also created a visual interaction between the foreground and the background.

The perceieved form created from the approach looked interesting visually and showed potential towards further development in any of the contextual objects mentioned in the brief.

225

Equal splitting

Whole culm bending The next stage of exploration was to see if the heat bending manipulation could be done to a culm without splitting the material and pasting it radially, thus reducing the efforts in the process. To bend the material it was necessary to split the material to a certain length. For this purpose, bamboo culm with a node on one side kept intact, was incorporated. The material was split with marking on the cross-cut surface and split with the splitter tool. A clamp was attached towards the node to control the bending.

Bending The culm was later attached to baby vice and heat bending techniques was applied to the splits. The splits while bending were difficult to manipulate due to the less space between the splits. This resulted in uneven radii across the culm surface.

226

Analysis of explorations The previous and the next mockup were kept together to analyze the forms and what direction could be taken further to contextualise it in terms of product development.

Both the form visually looked interesting, whereas in terms of feasibility the first exploration was appreciated by the craftsperson Prakash bhai. The aspect that the first exploration seemed to have protential towards radii manipulation showed more potential towards product development. The second exploration looked interesting in terms of good form transition from the node towards the splits, but the fluctuation in bending and restriction towards radii manipulation led to the decision of working with the first exploration further.

Marking pattern

With this exploration, long sticks were utilised for purpose of doing radii manipulation

Once a larger radii was achieved through heat bending, the task was to keep the shape consistent.

and to seek for modulation in axial orientation.

For the consistency, the shape was marked on the table with marker as a pattern

National Institute of Design

Step to step radii manipulation The sticks were bent and corrected manually with slight pressure and bent to exact shape. The long radii's were easier to manipulate due to even pressure applied while keeping the fingers tangential to the point of contact at the vice.

Preparing Jig To streamline the process of bending and making the radii manipulation consistent, G clamps were used. The clamps were fixed on the table with node pieces for radii manipulation at intended positions. A stick was put through the and heat was applied,but to the contrary, it was difficult to achieve the certain radii as the material tried to come back towards linear orientatiion.

Radii fluctuations & corrections

Trimming ends

Even thought the radii were consistent, the point of deviation was fluctuating dur to the variation in force applied by hands. The pieces were tried correcting by again marking the surface to heat and improve the angles and orientation.

This ending were uneven which were marked and crosscutted for consistency in the final form.

Glitches While bending the bamboo sticks, sometimes due to the excessive pressure applied, the sticks developed

Chiselling Supporting frame To create the frame, concave radii had to incorprated but now with larger height for extended support. A cross-cut piece with larger length was incorporated and chiselled to attach the sticks to the culm.

The attempt to create percieved form with interesting surface transitioning from the cylinderical form which bulged towards the top, was appreciated by the mentor and prakash bhai who helped in the making of the form happen, as well as the other craftspeople. The craftspeople held it, tried engaging with it and complimented the maker Prakash on his attempt to make the prototype.

Other self initiated applications by craftsperson It had been almost two months since there had been close engagement with the craftspoeple at the organisation, one of which was Prakash Bhai who seemed interested in exploring bamboo in newer ways and help in developing the prototypes with his skills,expertise and understandings.

It was Interesting to see a craftsperson being motivated to explore the material which contrasted with the objectives of other artisans, having the motive of working on task basis without questioning methods in terms of production and material manipulation techniques.

One such day, a home decor magazine was carried to the workshop to see the response of the craftspeople. As they flipped the pages, they were awe-stuck by the various languages of products which they kept of mentioning to each other, if it could be done in bamboo as well. The magazine was shuffled and seen by Prakash Bhai,who was also awe stuck with the various forms and products shown in the magazine. Few days later, some of the interesting visuals in the magazine were translated through the current technique into utilitarian forms and few interesting explorations.

This aspect showed the potential for doing motivation based interventions with the craftspeople, where there is space for ideas and concept, not bind by the designer's intuitive understandhing, but are open to the craftsperson's developed sensibilities and thus can result in a positive collaborational effort towards these kinds of prototype and product development. This would also connect to the livelihood aspect and intervention which can take place, even at the cluster level.

As these explorations were appreciated by the other artisans as well, it was interesting to notice the enthusiasm of Prakash bhai growing out of his norms of working with the accustomed way of manipulating the material on daily basis.

He even had happened to share the interest in making some of the concepts at home and see for the possibilites of selling it locally.

Exploratory works by craftsperson Prakash Bhai,replicating the techniques intuitively for other application while getting triggers from publication materials and seeing possiblities.

Making frame using culm crossection From the understandings of previous explorations, the other trial was to seek for structural support by using parts of bamboo to reconstitute the material in a newer orientation and see how the structural aspect is translating into aesthetic aspect.

Bending

Applying water

To Resolve the radii better, a cross cut pieces was attached to the vice and stick were heat bent by applying tangential pressure. The inner lumen being softer than the outer skin, made the transition of radii from linear orientation towards the deviation better.

Fixing The task was to fix the modulated sticks to fit into the grooves created on the cross-cut ring as well as the knot piece.

The vertical form transition was interesting as the slight radii manipulation inwards and the tension provided by insertion of the sticks into the node and the crosscut piece created an interesting sihoutte.

The realised drawback was the tension created from the sticks inserted into the crosscut ring, which resulted into a crack.

Attempting a feasible product prototype After a good amount of exploration with the material, it was time to try making a feasible prototype with a certain application. With the visual language of the prototypes it was suggested by the mentor, to make a tabletop lighting product for either as a souvenir product for visiting guests at the workshop or for the tourist market.

It was also important to define the factors with the approach of making a feasible product prototype, so as to understanding the sensitivity and sensibility to create a product prototype yet a feasible finished product and validate the production processes involved in the making.

In order to create a tabletop lighting, which could fit the criteria for product development with the understanding developed, and deliver the product at the earliest according to organisational pressure, it was decided to use LED lighting fixture for the exploration.

Detailing of the product was an important factor to show the potential of the tecnnique explored. The detailing could make the judgement of the feasibility of the concept.

The surface finish, the radii on the surface and the overall aesthetic quality through tangible intervention had to satisfy the tactile and aesthetic perception of the product prototype.

Product prototype development Lampshade The lampshade was developed as per the technique and specification to check between concept and product development.The lampshade being a component of the product was supposed to be suspended on a stand which was also intended to supply electricity and also to make the LED light integrated into the culm frame, work and stand together as a structured form.

Another smaller hollow culm was sorted and sanded which could pass the wire to the frame and get attached to the cavity on the stand and the lampshade.

Varnishing

After sorting all the pieces to create the product, the task was to get the pieces varnish,prior to the product was developed. The intention of doing this was to get all parts varnised,in order to seal the surface and prevent the surfaces from fungal or climatic attacks.

After assembling all the parts, the intended form was given slight inclination at the surface joint of the stand, to correct the centre of gravity.This aspect gave an interesting visual non-conformity to the whole form which could other wise had orientation at a right angle.

Being wired from inside, made the whole form look unobtrusive in terms of its function. The visual functional aspect was depicted by the form configuration of the bamboo sticks which created a perceieved form of a lampshade.

In terms of feedback from the organisation and craftspeople, the reactions towards the prototype were very positive and made them realise the importance of realisations while working on the design process while creating the prototypes. This was a major positive motivation towards the applications of various understanding and seeing its application being manifested through material interaction.

The lampshade was connected and lit in the evening light at the workshop, to test the prototype and see its performance and perception as a actual functional product.

The LED light attached at the culm made the whole frame lit from inside. It highlighted the fibres exposed from the inside very well and provided a nice diffused ambient glow due to the usage of a diffused lighting source. The radii manipulation near to the light source, was also highlighted from the light source in a even transition from the point of origin to the tip of the sticks.

The vertical sections are essentially rectangular with a slight convex and concave curve from top and bottom.The wider longitudinal splits 'slats' were observed mostly to be used for making seating surfaces, fencing, furniture component.

The longitudinal sections as longitudinal Half & Quarter were either processed by hand or other wise with splitting tool. The sections were mostly processed at once, at the workshop in bulk and stored, and used whenever required for production purposes.

Establishing Context The different types of longitudinal sections from the crossection surfaces, could be perceived to provide a lot of opportunities in terms of product development.

The previous set of explorations provided the base to manipulate the sections and to create perceieved volumes. The next step was to seek for surfaces, which in itself could be pave way to various possibilities in terms for product development in cafeteria context.

Ideations for surface development with an intent to create surfaces which can be checked towards its feasibility to be translated into forms and create a form language for potential product development direction

The following exploration was intended to generate insights about the execution of the concept,production processes invovled,physical properties projected and how the exploration could be taken forward to seek for possibilites further. One such concept was to create a tray sort of form, utilising the natural green epidermal layer of bamboo and the bending properties the material provides.

The process involved making splits from the same technique used above, but without the shaving of edges. The sections were then taken to planer machine to make the edges falt at right angles.

Next stage was to bent the sticks to a defined angle and align them all for consistency. Later the sticks were glued and clamped together using a plyboard to press the surface and g-clamps to hold them to firmly join the sticks parallelly in order to create surface.

249

Inferences from Prototype The prototype which manifested through processes in the end was quite like the initial concept, but making it to the exact configuration took a lot of time in development. The aspect of doing radii manipulation towards the edges was a tedious task as the radii and the material flex back to a certain angle as the material cooled thus resulting in fluctuation of the angles.

This aspect and the aspect of putting a lot of labor and time towards the prototype development, led to the dropping of this direction and other directions were simultaneously explored to seek for feasiblity and consistency to formulate a design language for the product development further.

251

Understandings through Stick manipulation The explorations done under stick (longitudinal splits/sections) manipulation was an interesting area to explore that created an understanding towards natural processing of material and, how a part which was being utilised for a certain purpose was being utilised for another direction, keeping the parameters of production in context and that led to the manifestation of interesting prototypes.

The forms were later translated to utilitarian contexts of lighting and tabletop explorations that could have translated to a potential directions, but due to the time being taken to develop the prototypes and the various production aspects and detailing issues, the exploration failed to yeild towards a feasible potential way to develop products.

The explorations also created understanding towards the engagement of craftspeople with the material as the activity was community oriented and which at a time made the tribal crafts people gather together to create the longitudinal sections while talking and manipulating material simultaneously. The activity was perceived to be a meditative and the task to make the sticks rounded using the knife,where the knife moved on the surface of the material in a two and fro motion, was seen to be rhythmic.

Also for the fact that the product development criteria required the products to fulfill the product development criterias to be efficient, production friendly, economic, durable yet marketable, this technique questioned these factors thus creating doubts to be taken forward towards a potential product development direction.

While discussing this direction with the guide, it was realised that the technique was already being establised by traditional craftspeople and contemporary market and thus failed to create a newer direction or perspective towards bamboo craft and also as a student from Lifestyle Accessory design discipline, created a dilemma whether to take it forward towards product development or to address the context through other ways of manipulation.

The manipulation aspect of the material with the usage of heat was also an interesting factor to observe. The process of heating the sections, which led to the weakening of the fibre and, modulating it to create elements with orientations i.e. radially as well as parallelly, led to the discovery of creating volumetric perceieved forms.

Being looking at various properties and aspects of the parts of bamboo, the slivers of bamboo were examined under sunlight at the workshop. The thin sliver being seen semi transluscent, could let the light pass through it, highlighting the fibres in an intersting manner.

While looking at this property, the sliver's fibrous linear texture were being highlightedin a vivid manner, which triggered the exploration towards this optical phenomenon. The surface texture of the sliver relflected light, with a nice sheen mimicking the finish of gold with matt finish. The next set of exploration were done to seek for possibilities with the observed aspects.

Exploration of sliver units to create a surface The initial attempts were to seek for making a surface, so as to create a base for exploring the material further in terms of product development and thus look at the possibilities with the sliver units. The sliver units were initially overlapped linearly and then pasted to seek for a surface which could be translated into forms.

After pasting the sliver units together, the next attempt was to see if the units could be formed or moulded on to a form so as to loop the whole pasted set and gain a form that can hold itself and also acquire structural strength.

Initially a single sliver unit was looped on a bamboo culm and pasted. The next step was to mould and loop the whole pasted set onto the culm as a support.

The attempt did not work out and resulted in splitting of the slivers as the overlapping of individual unit created a shearing tension on each other, thus resulting into splitting of the fibres.

258

National Institute of Design

Graduation Project Doc.

The overlapped sliver unit as a surface, was examined under a light source to seek for insights. The light source illuminated the fibre structure of vascular bundles in a aesthetically pleasing manner and the thickness of the ply allowed the light to pass through the surface in a diffused ambient manner.

This was seen as positive aspect and a good trigger to explore the technique further and seek for further validation in terms of feasibility towards product development.

Sumedh Sonare

Expl. Bamboo products for spaces

259

The next step after obtaining a surface and its linear interpretation was to manipulate the properties of ply based material and try exploring forms which could hold the fibre structure intact. The initial trial were to explore the material by bending and looping.

The slivers being fragile,if bent at very acute angle, developed splits and eventually cracked. This aspect was noted and other ways of exploring the plys were ventured.

The slivers were then looped together in different angles to create forms and then check for further possibilities.

The looping created the possibility of being bent,without affecting the fibre structure and splitting or breaking the ply.The loops were intuitively perceieved futher to see how by overlapping the loops ,could aid in creating a structured form which could have a good strength over single ply. A miniature mock was explored which showed further possibilites towards taking the approach forward.

The mock up was then scaled up to see, if the intuitive mock up could get overlapped and have a good transition of ply happening and also checking if the the structural support could be strenghtened.

The scaled up mock up was later checked with a light source to seek for validation, in term of luminosity and the permeability of the surfaces of the ply to let the light pass through.

The effect of the light coming through was perceived to be ambient and due to the trial of warm as well as white light, showed potential in terms of taking the concept ahead and see if the overlapping ply structure could be made more stronger and also provide structural support to have a utilitarian perception and potential for taking it as a direction.

The linear sliver unit surface was again explored with structural support to see how the structure holds around a frame.

The exploration was done by creating a structure around which the slivers can loop.

The structural frame was created by drilling three holes onto a knot cross cut bamboo node piece and creating cavity to insert bamboo sticks. The sliver units were pasted with adhesive one by one by overlapping one unit on top of the other.

While, the whole structure together with the pasted sliver units looked interesting, the durability aspect was still in question as the sliver units were acting as a diffuser but structurally were fragile with the given thickness of the units.

262

To tackle the durability and structural aspect of the surface, one option was to laminate it with another surface which was transparent and even enough to hold the aesthetic quality and permeability without compromising on the structural aspect of the surface.

For the purpose, a limination sheet was purchased from a stationary store and slivers were pasted onto it,one by one to create a surface.

Understandings through Sliver manipulation The slivers explorations were initially experimental attempts that were explored as the slivers could be stuck, layered and transformed into forms.

The forms were later translated to utilitarian contexts of lighting and tabletop explorations that could have translated to a potential directions, but due to the time being taken to develop the prototypes and the various production aspects and detailing issues, the exploration failed to yeild towards a feasible potential directions to develop products.

Also for the fact that the explorations in the project's context required the products to fulfill the product development criterias of being efficient, production friendly, economic, durable yet marketable, this technique questioned these factors thus creating doubts to be taken forward towards a potential product development direction.

While discussing this direction as well with the guide, it was realised that the technique needed to fit the cafeteria context and also be consistent as form language and also to be taken further in terms of other defined contextual products according to the refined brief. This aspect was thus considered and other parallel explorations were looked at for further enquiry to fit into the defined context.

Structurally fragile and requires the use of fresh culm which may be suseptable to biological and chemical agents such as fungus and molds.

The laminated surface and the form creation could hace resulted in potential directions, if the sliver units were structurally strong at the thickness level.

The threat aspect was majorly the biological and climatic attack factor to the sliver units as the technique required the usage of fresh culms, of which slivers could have good permeability towards light.

Other threat was towards the durability of the structure as the slivers were vulnerable to splitting due to the thickness required.

Highlights the inner fibre structure and explores the flexibility aspect of this manipulation of the material

The usage of plastic with the natural material was a major dilemma in terms of creation of products which would have questioned the ecological relevance aspect.

There was still further possibilites towards making it feasible,but due to time constraint, the direction was dropped.

Crossection based explorations Working with various form aspects of the material, the transverse direction or the crossectional portion of the material seemed unexplored in the context of the organisation and otherwise. Going through the repository of bamboo products I came across while doing secondary & primary research, there was a realisation that there were very less explorations and products explored with it. In order to generate understanding towards this aspect, further field study was carried out to validate this aspect.

During the time of field study, there was one observation made while looking at the material wastage being created during product processes. The observation was of the cropping of basel segment as it was not utilised for any production purposes and was later collected to either make nails or majorly burn outside the workshop to dispose or make charcoal out of it.

This insight was looked in form of opportunity to see if obtaining crosscut rings during the time of production, could result in holistic usage of the whole part of the bamboo material.

Moreover, looking at attempts in this direction at the workshop a cuboidal furniture made from cross cut pieces stuck together on a plyboard with glue and having a lot of negative space.The thought of reducing this random clutter as well as the the distribution of randomised unconcious negative spaces and making a uniform surface was the starting step in the exploration of this direction.

The purpose was also to look at a development of composite surface,while understanding and testing the property of the material when joined with pieces cut in transverse direction, and also to seek for possibilities for futher intervantion towards product development.

Cutting the culm on the roundsaw bench press machine with a stopper to maintain even thickness.

Exploring shapes & surfaces After obtaining cross cut pieces, the next step was see how interesting shapes could be created by connecting one shape to another. The easiest was to glue the round pieces together but due to the less surface area at the contact point, it was necessary to create edges that could impart good surface area for sticking. Thus, initial surfaces were explored.

The cross cut pieces are cut initially in square shape with a chisel tool and hammer. Due to the orientation of the fibres of crosscut pieces being in vertical direction,it was observed to be easy to use a chisel and achieve the shape by hammering the tool with a force resulting in splitting of the piece. Later the pieces were stuck together with an adhesive. The sample initially was a exploration, just to validate if this technique could workand it did. On this basis, further more explorations were done.

A jig made to replicate the shape

The next stage was to develop a method with which the pieces look exact similar in shape and measurement. A jig piece was made as a mock to replicate the shape in all the crosscut pieces.

Another important aspect also was to look the the constraint of inner and the outer diameter as the inner sides contain lumen which is delicate as compared to the area towards the outer diameter which has the

To replicate, the jig piece is kept on the crosscut piece and marking is done with pencil around the edges. Using the chisel tool and the hammer, force is applied on the marking, which splits the piece. Similarly this is done to all four sides to achieve a square shape and later is done to the other pieces.

After figuring out the technique to replicate the pieces, the next task was to see if there could be variations in the shape as per the removal of the sides,outside the marking. This gave the possibility to explore various patterns.

Combination trials while playing with the shapes to observe the various possibilities with the technique.

Exploring various shapes & surfaces Looking at the possibility of creating surfaces, the next task was to see if the surfaces could be translated in terms of forms. To create a form with square pieces, a bamboo culm of outer diameter of 5 cm and inner of 1.7 cm was taken. Next step followed cross cutting it into thickness of 8-10mm and a jig piece was created to replicate shapes with the process defined above.

The next task was to arrange the pieces in a grid and glue them together.

For joining them Bond-tite adhesive was used as it consists of resin based and hardner based material used extensively at the workshop to glue furnitures and structures. Thus 3X3 grid surfaces were created and

The next stage was to champhor the edges of the joined surfaces so as to joint the pieces at 90 degrees.Using sander device, the piece was kept inclined at 45 degree and the same process was repeated for 5 more sets.After removal of the material and making the angle, the next step was to join the pieces together with Bontite.

The shapes together,making the whole form gave an interesting play of shapes,light & shadows creating an engaging play of light and shadow. The visual as well as physical weight together were also making an interesting point to consider towards the directions of product development. The form was also appreciated by the craftpeople as well as the mentor and staff. This boosted me towards considering the direction as positive approach for engaging with the concept of joining the pieces in interesting ways.

After looking at the various combinations with square as a shape, various shapes were explored considering the limitations of the inner as well as the outer radii. The shape below was constructed with understanding of the geometry on the surface of the cross cut pieces as a balance between the inner skin as well as the outer skin had to

be maintained, so as to not let the pieces crack.

Once the pieces had been chiselled into rhombus shape, the pieces were analysed by bending them by had to see if the crossections could individually hold the shape and not split.

The pieces were verified to have good strength to hold themselves

individually and let were arranged in various patterns to seek for interesting surfaces.

The later step in the process was to develop a surface by putting the units together to form surfaces by gluing them together with a strong adhesive. Bond-tite adhesive was used here as it consists of resin based and hardner based material used extensively at the workshop to glue furnitures and structures.The pieces were glued initially and later fixed on a bench vice to make the joint stiff. Later the pieces were observed and analysed to see if the surfaces holds themselves. The units did hold themselves together and were stiff enough to be made it a form.

Yet at that point of time due to the jaggeredness of the edges, it was still though to explore more shapes to see if there was opportunity to create shapes,translate them to surfaces and then seek for the possibility for creating forms which could be defined a certain context in terms of function.

The explorations till a certain stage, showed a lot of potential to be carried forward in terms of potential direction, but it was also important to compare the different techniques used, to realise the positive and negative aspects and the factors informing the product development process.

Comparison Study {between techniques} Bamboo stick

Split based

The explorations done under stick (longitudinal splits/sections) manipulation was an interesting area to explore that created an understanding towards natural processing of material and, how a part which was being utilised for a certain purpose was being utilised for another direction, keeping the parameters of production in context and that led to the manifestation of interesting prototypes.

This technique in comparison to stick manipulation projected less potential & mostly towards only one application, out of the objects defined for the contextual brief and its requirements.

Also for the fact that the product development criteria required the products to fulfill the product development criterias to be efficient, production friendly, economic, durable yet marketable, this technique questioned these factors thus creating doubts to be taken forward towards a potential product development direction.

While discussing this direction with the guide,it was realised that the technique was already being establised by traditional craftspeople and contemporary market.Thus failed to create a newer direction or perspective towards bamboo craft and also as a student from Lifestyle Accessory design discipline, created a dilemma whether to take it forward towards product development or to address the context through other ways of manipulation.

The techniques needed to fit the cafeteria context and also be consistent as form language, in order to be taken further in terms of other defined contextual products according to the refined brief.But because of the constraints of the material being suseptible to damage from physical,biological and climatic agents ,it was thought to be paused till other interventions were not figured out.

Cross cutting This technique of manipulating the material showed the scope towards further development in comparison to other techniques yet explored. In terms of approach,language and various feedbacks the exploration was fullfiling the various criterias which were essential for the direction to take forward.

After consulting my guide, this direction seemed potential to take further and also to explore the direction towards translating the surfaces to forms and looking at the possibility to create a visual form language towards product development.

Also the task was to observe how the craftpeople could be engaged into the activity or into production stages which was the prime motive of doing the intervention.

Thus, Jigs were constructed, followed by removing material on the cross cut pieces, joining them together and later sanding them to obtain a composite surface which could be assessed for potential applications.

The wider edges were intuitively thought to provide good surface area to let the pieces stick to each other this taking the tangencial forces of the weight of each other .

Geometric construction of modified hexagon shape which fits the requirement providing good enough surface area to replicate the crosscut pieces derived from basel segment.

Once the shape was finalised, the Shape was then translated to a thicker board, in this case a plywood. The shape was constructed again on the surface due to the unavailability of printing services in the village.

Task 2 Constructing jig After the creation of the jig, the next step was to remove the material by marking the crosscut pieces with the jig and use chisel or for precision use a cutter blade while placing it a millimeter away from pencil/pen marking parallelly and hit it with a hammer, resulting in splitting of the crosscuts. The removal of shape seemed like a relatively easy way to process the pieces as the blade effortlessly splits the material due to the material property of vertically splitting.

The process was similarly repeated for other two shapes being constructed and converted into a jig. The technique is again being utilised to obtain the shape from the round bamboo rings by splitting with force with hammer on cutter blade transferred to the rings.

Task 3 Arranging the pieces

Regular harmonic arrangement

Irregular nonconsistent arrangement

There were two variation in terms of shape arrangement which were tried with the craftswomen as well as on the software to check for the interaction of shapes and to find opportunity with the play of tessalations .

The regular arrangment had good consistency where as the nonconsistent arrangment of the hexagon pieces were much jaggered to resolve into further development as forms.The regular arrangment was check for a trial to understand how the array visually looks together.

The regular hexagon and the square crosscuts were arranged in a regular manner as the pieces allowed a less scope of regular arrangement in terms of creating a composite material sample.

Task 4 Gluing pieces together

The next step was glue the pieces together. The grid was decided and discussed with the craftswomen for the orientation and the pieces were glued together using Bondtite as a adhesive. The adhesive's both parts were mixed together in a container of made from the node part and applied with a bamboo stick. The pieces were kept on newspaper, kept over a flat plywood surface evenly while applying the glue to the edges.

The grid on the left was chosen to attempt a first trial of the surface as it seemed visually consistent with the surface lines and play of modified hexagon,hexagon and deformed ellipses. To see if the grid could actually be tested and made into a surface, it had to be stuck together to understand and analyze the surface.

Task 5 Sanding the surface

After achieving the surface, the next task was to make the surface even.

For the purpose a grinding tool was used with sanding attachment on the head. The composite surface was kept on a flat surface and very intuitively the whole surface was sanded by the craftsperson to make the whole surface even.

The composite surface obtained after sanding both the sides had made the grain texture(of vascular bundles) of individual pieces more highlighted. This visual property added a nice value to the composite structure which had a good visual interaction of lines and irregular organic elleptical shapes complimenting the intentional geometry with natural occurrence of the shapes.

The first impressions shared by the craftspeople and the member of the organisations towards the attempt was worth notingThe surfaces were perceived to be very different the objects and manipulation techniques they had came across.

The craftswomen who had helped in the attempt even appricated and was amazed by the combined effort and the result of her intervention in making the surfaces.

The members of CIBART including the mentor appriciated the development and were speculating the processes involved asking if the the prototyping method was CNC routing and how was the cavity achieved :) The tangible apsect of the material was also appreciated in terms of its grip and weight on the hand.

The vascular bundles texture on the surface of each individual pieces created a interesting interaction of the grains towards the three converging points. As the majority of grains were concentrated towards the apex points, combined they created an interesting gradiation pattern moving radially from a piece to another. The joinery lines between units guided the eyes to flow in a visually interesting manner.

Analysis The whole process from the crosscutting of the bamboo rings to the sanding was an interesting process and showed the scope towards further development in comparison to other techniques yet explored. After consulting my guide, this direction seemed potential to take it further and also to explore the direction towards translating the surfaces to forms and looking at the possibility to create a visual form language towards product development.

The interaction of various shapes on the surface was much appriciated by both the mentor,staff and the craftspeople.The cuboidal form was also perceieved to be new, in terms of approach and language and various feedbacks while holding the form by craftspeople as well. This pushed me to seek for futher more exploration and inquiries with this approach. The translation of surface to forms had to be explored and understood to seek for potential applications.

The grain structure which was made visible through the production processes, also gave the insight to understand the geometrical pattern and what could be understood from geometrical persepctives towards product development

Paper Prototyping

Exploring forms MDF prototyping

After the understanding developed by reaching a good stage of surface developments, the next task was to seek for possibilities in terms of creating forms with the context of developing cafeteria products and how the various form aspects would inform towards the usability as well as functionality of the forms being developed.

To gather more understanding towards translating the surfaces to forms, various methods of prototyping were used from paper mock ups,MDF mockups and bamboo mockups.

The process of creating forms was very organic in terms of sequence of creations and insights were derived to understand the product development from the perspective of skills involved, time taken, manipulation techniques,unit production procedures.

Paper prototypes

The initial method of form translation was done by printing the grid made on adobe illustrator on 200 gsm paper and later holes were punched using hammer and a punching tool to give a natural form based physical association with the crosscut bamboo rings.

Using cutter and scotch tape, the forms were cut at cavities, half cut at folds and stuck together to make forms. The forms initially showed various potential directions towards cafeteria context. In order to get more persepctive of how the forms will eventually get translated into 3D, the forms were then decided to be tested on MDF. MDF (Medium density fibre) board being easy to manipulate and to achieve an understanding of how the forms will eventually get translated,was the next step for prototyping before taking it to bamboo.

MDF prototyping The prototypes done initially gave a good insight towards the the possibilities of combining the units in various orientations to yield utilitarian contexts. The objective was also to seek for consistency and derive a language for the objects being thought for cafeteria purpose.

Also the various forms had to have a good structural strength as the attempt of using crosscuts for product development, were not seen during seconary research and were explored further till a certain extent during material exploration.

The pieces were either joined at 90 degrees or at various different angles to look and understand the structure forming in organic geometric manner.

The various forms being created were also realised to be platonic solids. These forms were studied more in depth to understand their significence and seen if the attempt could resolve into a interesting direction to yield meaningful output.

Analysis The explorations done with MDF, provided a much greater outlook towards the potential the forms explored had, which could lead to potential directions. Each prototype to a certain degree, showed a good potential towards contextualisation towards ideation , but at the same time it was realised that the understandings that the prototypes, also had to be tested with the craftspeople for validating the feasibility aspect, labor invovled and potential for putting into production of the prototypes. Out of the various MDF explorations, there were two languages being highlighted which seemed potential towards developing further prototypes and checking for feasibility towards the given context.

The first language was connecting square units at 90 degrees and look at the aspect of creating perceived volumetric forms with less unit processes,manufacturing cost and yeild towards feasible conceptual directions with utilitarian value.

The other set of connections were defining a language which had a cohasive repeatation and resulted in reoccuring forms. These reoccuring forms were not apperent while the paper mock-ups were created and tested. The forms seemed to have convexity and concavity which intuitively were imagined to probablity be contextualised towards utilitarian possibilities.

304

National Institute of Design

The two languages were thought to be explored further and checked for the feasibility through ideation and further mockup generation.

The various directions being intuitively joined to seek for forms, gave insights to possibilities once the shapes were translated to forms.

Analysis To explore further possibilites with the defined forms, it was important to contextualise them according to the their usage in the cafeteria space. The cafeteria elements having defined utility functions were further catagorised for better understanding of contextualisation of the elements, according to the space.

Pattern Jig development In order to aid towards consistency of the splitting of the crosscut units, a jig pattern was made on Adobe Illustrator, which had variations in size and were marked with increment according to one side of the shape.

The intention was to create a set of shapes which would be picked and placed on the crosscut unit to check of the availability of the inner and the outer diameter and then used as a reference to mark.on the surface of the crossection with either with pencil or pen and later would be a visual guide to split the surface using a chisel or a blade with hammer tool.

This method was supposed to ensure the consistency in shape and streamlining the production process through the usage of the shapes.

This aspect had considered the previously noted point from expert's review of quality control and standardisation to aid towards well formed end product and also aid towards the increasing the efficienct for the production.

Punch tool development Another method was also tried to seek for a simpler way to make the splitting process faster by making a punch tool which when kept on the crosscut unit and hammered could split the unit into a positive shape of the punch.

Initially a punch mock was made with paper to get the dimension right and also to get an idea of how the usibility of the punch would be defined through the form of it.

The mock was then translated into actual material where mild steel flat bars were measured,cut,welded and grinded to make a tool component. The other components were later welded to the make a handle for holding and hammering.

Once the tool was made, the tool was tested on a crossection and observations were made. The tool failed to split due to various factors.One of the factors realised was that the bamboo fibres grew in a spiral orientation which did not let the tool to pass through when punched and create a shape. The other factor could have been the angle devised for the punch blade.

From these issues, the tool was realised to be worked later with better understanding of tackling this problem and the technique of marking with jig was chosen for taking forward.

Product Development The next step was to utilise the understandings generated from previous explorations and seek for feasible product development direction while considering the criterias of quality control and standardisation in terms of unit processes and production.

A good consideration was also given to maintain the natural texture and tangibility in the whole process of production and in terms of product outcome to ensure that the product has better value perception in the market.

Development of Tong Looking at the units and the context of cafeteria, another concept was explored in the form of tong concept as tongs were observed to be used at various restaurant and cafeteria settings with the purpose of extension of hand to grip or lift food objects.

There seemed to be various reasons to why the tool is used, from picking food objects that may be hot which may require an extended grip support to lift food object from one point to another or for hygiene purposes to not allow the hand to touch the food content and be picked with a tool used by various users, and also provide a way to move, rotate and turn the food with delicate precision.

Observing all this aspects and thinking of contextualising the tong for cafeteria space with the defined techniques, concepts were explored in terms of visualisations and direct material manipulation.

314

National Institute of Design

Graduation Project Doc.

Initial attempt to create a tong A tong prototype was created by taking an ideation concept ahead which utilised a square unit and longitudinal wide outer splits. The outer splits were manipulated carefully by splitting the section with 5 mm thickness and then removing material by sanding the split on the sander machine to achieve a concave radii. The thicker section served as a joinary base

to the square unit where as the thinner section served as flexible length due to the property of the material and which could be held and pressed from both the sides while keeping the object in between the splits to be gripped.

The splits and unit were joined with araldite adhesive and for reinforcing the joinary, drill of 3mm were made on the corner part of the units which had good thickness.

The edges of the tong were sanded to create a convex radii on both the splits which when pressed towards each other,closed the splits onto each other in an interesting manner creating a click sound thus enhancing the experience of the user to engage with object.

A jig marked with side length of 4cm was taken according to the crossectional availablity.

Tong Prototype Prototype development Another prototype was worked out utilising the learning from previous model and extending the arms for better flexing of splits as the previous model needed more pressure of being pressed by the thumb due to to the short radii formation.

This prototype utilised the usage of split of longer length manipulated along the grains on the sander machine to have a variable thickness for sticking onto the square unit and thinner section for pressing the tong and forming a cone and utilsing the proximity of the arms to grip food object.

After sticking the splits to the unit, the piece was kept under the sun for drying for an hour. Later the piece was sanded intutive on the sander to even the sides of the splits and bring it till the thickness of the units. The crosscut unit area was rotated while sanding to make the patterned surface of the grains visible.

Development of Cutlery Holder The square crosscut units were explored in order to create a form utlising the cavities with the intention of using less machine intensive manipulation and aiding in product development which could be focused at both the organisational level and cluster level.

The forms were first sketched on paper to see how the form and its cavity could be a played with visually, defining the form characteristics. One of the form was sketched while ideating and it seemed interesting as the form could be utilised as a traditional holder at the same time the cavities could be utilised to put the spoons or the fork into it from any orientation.

Salt + Pepper Shaker From the previous explorations the further understanding where used to look at another requirement for a product which could utilise the form aspects for a utlitarian purpose for restaurant/ cafe context.

Looking at the cafeteria context, salt and pepper shakers were thought as an essential elements as these were majorly observed to be used for enhancing the taste by sprinkling action of the shakers, which act as a container to salt and pepper and the visible perforation on the objects acted as an outlet for the contents to come out.

326

National Institute of Design

Graduation Project Doc.

Ideations To look at the context and see how the form manipulation could fit into the defined criteria, ideations were done considering the presence of cavity and hollow form of round bamboo of variable sizes and wall thicknesses.

1.

The initial ideations were visualisations of the square units as a more of an open structural form being ideated as a holder and the hollow round bamboo tubes as a container to salt/pepper due to the form factor and effective usability characteristics.

The form/shape of shakers were ideated, considering the aspect of ease of production,standardisation and quality control.

2.

The next set of ideations looked into more semi open set of forms where the intention was to see if the rectangular form could either be overlapped or looped to create forms which could be oriented in multiple ways.

3.

The selected loop forms were later ideated while depicting the forms of shakers inserted into the cavities to seek for interesting applications.The insertion were ideated with straight,tapered and radii manipulated silhouttes of shaker which also was intuitively perceieved from practical perspective to have a good tangibility in terms of gripping the form and using it while shaking the object to let the content come out through the cavity.

4.

While ideating, one of the ideated form showed potential towards being taken forward as the form utilised the cavities and the cyliderical form of hollow bamboo really well with the ideation of the insertion. This showed a good poosibility also towards the play engagement of both the shaker form and holder creating a rich multisensorial engagement.

can be processed and taken to next stage of production.

The next task was seek for a pattern of the surface, given the geometric nature of the technique. To create the surface, the patterns were first explored on Adobe illustrator software to get a first hand idea of the tessalations, which could later be translated into forms.

The tessalated shapes showed multiple possiblities to create a surface which could be later translated into a tray surface. For the validation, a sample surface was already tested to seek for creating a prototype which could hold its weight,given the composite nature involving individual elements to be joined together.

The tessalated patterns were analysed to be taken further towards prototype stage considering the joinery pattern, the orientation in which the tray surface would be held in.

Out of all the tessalated patterns, the first pattern was thought to be taken forward given the angles at which the units were joined to provide support with cross agnles,as well as the product semiotic factor of having rectangular shape signifing a tray surface.

Creating tessalated surface A print out of the pattern with a defined size of 3.5 cms as the unit size ,was chosen and printed. The cut out rings were pasted with araldite on to the print out as a base to stick on, while assuring the pattern to be at the defined place of positioning the units. The tessalation was divided in two sets to manage the sticking process with ease as the pasting were done manually,considering the perfection in pasting the units at a specifed spot.

The process for the units to get stuck, took about an hour to dry completely and later the sets were removed and pasted again together and tied around with a masking tape to hold them in place, till the whole set gets glued to each other.The surface was then sanded on a sander machine to make the surface even.

Create support structure Given the composite like grid of the tray surface, the next step was to figure out concepts to contextualise the surface towards a tray associating form and defining a visual tangible utility.

Ideation

The ideations were visual explorations of either handles or support structures which would aid in holding or lifting up the tray and yet as another element, would do value addition to the overall form.

One of the ideation looked interesting enough, to be tested on the surface, as the flow and consistency of the unit looked cohasive.

Sumedh Sonare

Expl. Bamboo products for spaces

337

This ideation was done by visualising the form with inclusion of radii manipulated bamboo sticks, which would have the function of being supports to be picked by the hands, at the same time act as a barrier to the objects kept on the tray surface.

The edges were supposed to be stuck with crosscut unit inclined at an angle and drilled to make cavities on both the sides.Bamboo sticks with radii manipulation, inserted into the cavities and sealed with glue was visualised for the purpose.

Testing orientation

The tray surface was checked with cross cut pieces joined at the edges at an angle with masking tape to check for form resolution and also see how its working cohasively. As the surface had taken time and effort to develop, another mock prototype was initiated to seek for fair understanding of how the structural support would take place.

338

National Institute of Design

Graduation Project Doc.

Stuctural support mock-up The first trial was to heat bend 5-6 mm dia bamboo sticks for manipulating the radii to 20-30 degrees. The crosscut units were then drilled with 3mm drill bit at apex point on both the sides of the cross cut units for insertion.

There were variations in radii's so as to seek for shapes which could aid in better grip, yet be a good support for the purpose of being held and carried by hands as a serving tray. To strengthen the units stuck at angle at the corners, 3mm holes were drilled and bamboo sticks of 3.4/4 mm dia sticks were inserted into the contact point for reinforcement.

Overall, the whole form with the different elements composed together, looked quite cohasive visually and seemed interesting to hold as a tray form with support structure. The various radii being tested, individually resolved into the cross cut units quite nicely. This exercise drew its influence and understandings from

form, form & emotion module where the concepts of form integration and resolution of form was understood and applied here due to the relevance of the understanding in terms of visual and tangible aspects of eye movement around the form and touch of the surfaces.

The mock-up was shared with guide to seek for clarity with this direction. But as this approach did not utilise the opportunity of using the natural cavities for creating efficient support, this approach was put on halt after the feedback, and further concepts were explored in terms of usage of cavities for support structure, and creating visually balance and composed supports.

It was also suggested that, another material for material combination could be explored for adding value to the form as a product prototype, which would enhance its value in terms of aesthetic quality as well as economic.

Tray Support Detailing Additional edge feasibility support ideations Further, other directions as digital variation were explored keeping in mind the usabilty, tangibility and structural aspect of the material and the feasibility of the concept.

The forms were visualised, considering the presence of cavities and how the cavities could be defined a structural function. Further, as suggested earlier, material combination was visualised in the form of support structure. For the support structure, metal rod was visualised with the surface which would add value to the over all form.

Validation for material combination

To validate the combination of additonal material with Bamboo, secondary research was done. The insights broadened the understandings towards bamboo traditionally being perceived as a poor man’s material.

Its contemporary connotation being cheap, flimsy, rustic. For this fact, combination of bamboo with materials which are perceived to be high-end or luxury materials,such as leather, brocade and precious metal were interesting in the preceived value of bamboo through association.

The ‘high-end’ material, when combined with bamboo, seemed to have the potential to pull bamboo up to compete in market segments where bamboo would generally not be accepted.

As a natural material, bamboo has been often perceived as used only for handicraft products. Combining bamboo with industrial materials such as glass, metal, textile and plastic allows the resulting product to take on a modern/ urban/contemporary/mass market aesthetic more easily than if it were made only of bamboo.

It was also realised through the research that Industrial components could lend bamboo a level of standardization and quality which was very difficult to achieve when using bamboo alone, without the investment of additional time and cost. With this aspect brass as a material was thought to be combined with the surface and seek for validations with this approach.

Development of Lighting products The lighting being an essential aspect of a cafeteria space was analysed through the spatial setting at saputara. The hill station being at a higher altitude had a pleasant weather during monsoons and summers and winters attracting tourists from Maharashtra and Gujarat alike. At the time of the visit to the setting during monsoons, the climate was cloudy and there was a presence of fog which diffused the light in the surrounding . From this it was infered that the presence of natural sunlight or ambient diffused light was working in favour of the space in terms of lighting the space and spatial elements.

It was also realised that additional lighting which could light the space and engage the visitors, could be another aspect to look into and by utilising the manipulation technique, could open new directions towards product development.

MDF mockups Taking the possbilites of form manipulation tried by sticking the mdf units, it was realised that the spherical/semi-sperical form aspect could be explored towards lighting.

The units forming pentagonal cavities and possessing circular cavities created an interesting outlook towards further explorations and the curiosity of creating a light source within the forms to seek for interesting play of light and shadow was later explored in the further mock ups.

While looking at further explorations, significent points to aid towards efficient product development were considered.

Further paper mockups

To seek for interesting directions in terms of exploring the form with two repeatative units, lasercut paper units with the pattern of length 4cm was chosen and stuck with masking tape from inside.

The different forms generated through pasting the paper based units opened new possibilites to explore and contextualise the forms towards directions for lighting. These forms were then contextualised according to various parameters and defined futher for better clarity of thoughts.

Form analysis The further mock-ups with 1:1 scale on paper provided the insight of multiple possibilites of playing with the form and obtaining various possibilities perviously observed.

Form

The form generated from the pasting of geometric shapes, had a volume with concave and convex surfaces which connected each other very cohasively. The presence of cavity possessing organic shapes and the creation of pentagon shape towards the corners created an interesting interplay of negative and positive shapes on the overall form. The repeatation of shapes in a radial,linear or both created an interesting visual aspect of the whole form which seemed to have created a language.

Light

The photographs shot under the natural light created a larger visual drama which was either highlighted by the light falling on the facets creating stark highlight,midtones and shadows.The cavity on the form also imparted another interesting visual aspect of play of foreground and background.

Orientation

350

National Institute of Design

The various orientations in which the forms were shot and captured, showed the various kinds of interplay of geometric lines casted by light falling on the surface and shadows being casted on the inside, giving a potential perspective towards defining these sets of form for the space where the forms could have a better aesthetic function.

Graduation Project Doc.

Form contextual analysis (for cafeteria space) Through the various aspects defined through the analysis,it was realised that the forms could have a interesting impact if positioned in the space to create elements of interest and have a better contextual utility in the form of lighting products, By analysing the three aspects of form, interplay of light and orientation, the context of lighting seemed to fit well,as the form had convex and concave shapes and volume. The perceived volume created inside could be ustilsed as a lampshade with a light source illuminating the space in an interesting manner.

One of the paper-mock up was hung with a light source inside to check for the illumination,the formation of shadows and interplay of light on the form and around the space where the light is falling.

The interplay of light and shadow on the wall seemed interesting as the light spread across the room in a radial geometric manner. The shadows casted from the shapes created a radial flow of shapes around the space and created a interesting sublte mood with the spead of shadows portraying a web of shapes with a sense of cohasivity.

Product development Natural dome

5units

The first attempt was to create dome form after the initial mockups. The task was to identify the correct angle at which the crosscut units could be stuck together and could make the intended dome form.

To achieve the angle, a lot of pieces were stuck through trial and error method in order to identify the angle,so as to seek for a form made from the material to validate if the technique works and understand the feasibilty aspect of the intervention and the challenges to tackle.

To create the form, two sets of components had to be stuck together. One component was the pentagon form with a convex vertex and other being the ring which is stuck in a zig-zag orientation.

The first attempt was to create the convex form. The form was chamfered at all the three wide edges at 23 degrees on the sander machine. The pieces were then stuck in sets of two, by resin and hardner based adhesive called araldite and held with binder clips which acted as a clamp.

The other component being a linear loop was stuck with the similar chamfer at 23 degree. While sticking the pieces, it was evident that the angle was not working well towards the joining and resolving of the edges as even after clamping the pieces on a bench vice, the pieces pulled itself apart due to the tension created on the joinaries.

THe form achieved, validated the feasibility of the concept idea but the issues of the edges not connecting properly needed to be resolved.

There were many trial and error done to get the perfect angle at which the pieces were supposed to be stuck. After sharing this issue with the guide, it was realised that other materials could be used to takcle the issue, which could not only resolve the form in an interesting manner but also add value to the form as an aesthetic element.

Joinary Explorations

The exploration were attempted due to the structural constraint with the previous joinary of joining the two units with adhesive. The form even though was resolved, the spacing between the units was a concern due to non uniformity, as the angle defined was not accurate.

The units were joined with either a natural material, or with industrial material to seek for validity and feasibility of the joinary and value addition due to the attempted combination.

Initial joinary was tested with a flat aluminium strips for its properties of being flexible and easy wrapping on the surfaces along the cavity.

The addition of the strips in form of joinary,aesthetically worked well and in terms of value addition, but in terms of feasibility did not resolve the issues of fastening/ locking of the joinary and not been able to hold the units in place making the structure slightly flimsy.

1 Cut units were drilled at the middle of the sides and inserted with aluminium wire and examined. The form locked well and gave a good rigidness to the overall form. In terms of feasibility, the method was fairly easy as it required the cavity making and insert of plain wires. As for the material used, the grade of aluminium being less & soft and showed undulations. This attempt was perceived to be feasible and to be considered later.

On the similar manipulation to the previous exploration, this utilised copper wire, drilled and looped to secure the joinary.

The usage of copper gave an interesting visual contrast to the material, but the looping of wire into the cavity with the use of a plyer was a cumbersome task.

3 The attempt was done with (stainless steel)thin grade of wires double twisted and looped from the drilled cavity. The joinary was flimsy as the pieces didn't hold the weight of the joinary well. Also, like the previous attempt was cumbersome for production.

The below attempt was again a loop, but the wire was extended on either side and looped multiple times. This gave the whole form an interesting contrast. The contrast had form associations to the tribal craft details and this aspect was interesting to understand.

The joinary otherwise was flimsy and less feasible for production purposes and needed more exploration.

The units in this were again drilled and looped with mild steel wire, but in a wireframe by streghtening the whole structure. The intention here was to seek for solid, yet flexible forms which could be contextualised into a playful utilitarian forms. From the feasibility aspect, the wires looked quite tacky and did not yeild a repeatative pattern to formalise into a potential joinary.

In this attempt, the pieces were looped with clutch wire, which has good flexibility and a slightly stiffer radii formation when bent.

The attempt being exploratory, showed the potential in this idea of putting the natural shapes in an interesting undulating grid and could yeild towards a range of exploratory forms. But due to the specifications defined for tourist market, the exploration needed to show feasibility and consistency in terms of a visual language continuing in all the products.

In this attempt, the crosscut pieces were joined with dyed cane sticks due to the material's properties being flexible naturally and bearing a good stiffness. The crosscut unites were drilled on three sides with a 3mm diameter of cavity and inserted with a cane sticks,measures and inserted into a structured form.

To resolve the form at a particular point, a convex polygon piece was created by chamfering and gluing the pieces. When shared with the guide, the attempt was appreciated due to the combination of a suspended units resolving at a vertex. The whole structure seemed rigid as well as flexible and could be resolved and taken towards potential direction.

This form, explored the flexibility and bendability properties of cane and created a consistent network of repeatative shapes and eventually created an perceived mathematical form of Icosahedron.

The form as a whole unit had both the properties of being structured yet had a play due to the tension beween the connected joints and the flexibility aspect conveyed with the usage of cane sticks.

This and the previous attempts showed potential towards taking the concept ahead and look for feasibility in terms of production and checking for durability aspect.

This exploration utilised the joinary aspect explored previously with copper loops, but instead of looping it, were inserted into drilled cavities made on all the three sides of individual units. The resultant form had a good form aspect with an interesting usage of copper wires intermingaling with the shapes in a visually continuous manner.

This direction was also appreciated by the guide and the concept was further explored towards potential product development direction.

Analysis of joinaries Overall, all the attempt were interesting from form, joinary and value addition perspective. In order to take one of the joinaries ahead for prototyping and also to seek for feasibility from production perspective, the three directions on the right from the overall attempts were chosen.

The aspect of interesting combination of material which provided the form with a structure yet enhanced the value perception was the key aspect of choosing the three explorations. These directions were further intuitively taken towards production prototypes, keeping the feasibility,durabiltiy and overall aesthetics into consideration.`

After looking at the potential in the possibilites of various joinary formations and also the feasibility check done towards creating an interesting form language, the next step was test this towards a feasible product prototype.

In focus was towards best possible ways of joining and using least steps in creating forms while considering the durability as well as the consistency of the shapes and the detailing involved with the attempt.

Drilling The first step as established through shape manipulation was to assess the wall thickness of crosscut shape and use the jigman jigs to check which unit of shape covered the surface of the unit well for vertical split. After cutting and processing all the required unit (cutting, sanding the surface as well as the edges) the pieces were marked at the centre of the sides of the unit and then using a 3mm drill bit drilled the surface.

Sticking the bamboo manipulated components The units were later chamfered on the sander at 22 degrees and checked for the accuracy in order to connect the pieces in geometrically consist format.The pieces did not stick perfectly, yet using a clamp and applying araldite adhesive and fixing the pieces on the clamp, yielded towards formation of connected loops. The loops were checked for tension between the members, but resulted in a uniformly distributed tension, thus could sustain the tension through the material's natural elasticity.

As the lampshade form was manifesting with the manipulation stages, simultaneously the source component of lighting was also conceptualised and worked on, keeping the architecture of the form structure in mind.

The context was to create a form which could accommodate the light unit and also hold the structure from both sides. The unit had to have good structural strength yet integrate with the overall form seamlessly.

Later through concept generation, it was realised to use bamboo node and use the cavity to accommodate a light source. While looking at various kinds of light fixures in the market, the LED chips which was arranged on a round PCB board and could be directly connected to 220 v electrical supply, was chosen due to its form factor and also the grid of 12 LEDs which seemed interesting to be utilised.

Out of the explorations done for the holder unit, the choice of a complete cylinderical form was chosen to keep the visual language seem simple and linear, as the focus was concentrated more on the connected loops.

This attempt also meant, reduced but efficient way to manupulate the node and accommodate the light source and also aidig in the structural support.

The node was drilled with 3mm drill bit to create cavities at 5 points which could connect the structure of loops with the insertion of cane sticks from the loop to the holder unit.

The next step was to laquer coat all the units before the structure was assembled ,so as to seal all the possible spaces for preventing the surfaces from any means of biological or climatic agents of deteoration.

The laquer coating was done with the usage of matt melamyne coating which was working in favour of the surfaces,as the surfaces were sanded to a finer level leading to the visibility of natural grain.

The grains along with a matt coating of melamyne give the overall surface, a very natural sheen which would be been missing and would have changed the surface perception of the entire structure, if only gloss melamyne was used,which could have made the surface look artificial or associated with cheap finishes of traditional handicraft products.

In order to establish and link the loops to each other, cane sticks were incorporated.

The sticks were measured and cut to appropriate lengths keeping the allowence of insertion into consideration. The cane sticks were also attempted to dye in order to do value addition with inclusion of colour.

Yellow pigment dye was chosen to dye the pieces and was done in a bottle filled with hotwater and dye.

The sticks were then inserted and kept for 5 minutes till the sticks soaked all the colour.

One interesting phenomenon was observed that the cane sticks absorbed the colour and created a fade effect. This aspect was taken into consideration and was included towards the holder unit, which visually showed the fade to colour transition from top towards the bottom.

The structure was later connected together with the help of measured cane sticks, and inserted into the defined cavity made with the drill and conciously leveling the structure to have a resoving form, from various orientations.

Crosscutting & Joining

As the technique being establish with previous attempts, this prototype used a bigger jig as the bamboo crossection was large and provided a wider surface area to split and obtain larger pieces The pieces were later processed on sander machine and worked out in terms of quality control and standardisation due to the usage of jigs.

The units were later joined with 21.5 degree angle which very efficiently joined the convex unit as well as the looped component.

Through this, it was inferred through manipulation that 21-21.5 degree angle was the accurate chamfer for joining the pieces together and reduced the forced tension caused by clamping the pieces together on a vice with an adhesive.

Creating holder and lighting component

Sanding cone component The cone component was visualised to resolve the form from top and be as a structural element holding the structure and its entire weight.

The cone was created from a piece of solid bamboo. The section was marked with a rudimentry jig made of paper,which was placed on the surface and marked with pencil. The culm was then taken to sander machine and sanded to angle between 35-40 degrees and matched with the convex form to check and judge its fit.

Joinary constraint While joining the pentagonal pyramid unit with the loop unit with linear brass wire, there seemed to be the issue to insert all the wires elements together as the center points of both the components, shifted due to misalignment also due to the orientation of faceted units.

To correct this, the directions of the cavities were understood and looking at this aspect, the shape of the brass wire fixtures were informed by initially bending the wire with plyer. The shape was manipulated while considering the aspect of value addition and functional utility which the wire fixture had to impart to the unit as well as providing a durable structure and distributing the weight evenly to the whole form.

Creating a jig A jig was created to bend brass wires to obtain radii manipulated shape which could act as a joinary to connect both the loop units to pentagonal pyramids and thus resolving the issues of angular overlaps.

Brass wire of 1.5 mm radii was bought as the usage of the wire as fixture element was thought to add value by the combination of material and the visual appearance in terms of colour of brass was realised to be in harmony to the natural colour of bamboo units.

The shape was further resolved by discussing the issue with guide, and an interesting radii and angle which were directed inwards was visualised to resolve the form well and was later taken forward.

Paper Napkin Holder Looking at the cafeteria context, paper napkin holder was also thought as another essential element as the object were majorly observed to be used for holding a set of paper napkins and also to enhance the visual interest when placed on table in restaurent or cafeteria context.

From the understanding of form manipulation of crosscut units into pentagonal pyramids seen in the previous prototypes, these forms were contextualised into a paper napkin holder by understanding the concavity and the flexibility of brass wires fixtures.

Thus the requirement for a product which could utilise the form aspects for a utlitarian purpose for restaurant/ cafe context was devised.

The napkin holder utilised the bent brass wires as an aesthetic as well as functional element which would not haven been possible just with a material alone. Thus a product carrying the consistent form language was created for the object context.

Tabletop Light The lighting units so far, showed the potential towards product prototype feasibility with the ceiling lamps.The lamps also showed potential towards being hung and creating patterns of light and shadows from a certain altitude in a space where the lamps are kept.

Understanding this the next attempt was to look at the apsect of creating the radial light and shadow but oriented on a surface as a tabletop lighting. So, in order to formulate this, the next attempt was to make a tabletop lamp which could be another feasible piece of lighting and portable enough to be positioned in the tourist market.

Initially the concept was visualised to orient the linear loops on top of each other and seek for a feasible concept.

388

National Institute of Design

The concept of stacking the loops on top of each other and to define a linear language was thought to take forward in the context of a tabletop lighting, kept in the interior of the shop. The pupose was also to create an engaging mood light which delights the visitors to engage with the space visually and appreciate the form and the form factor of the product, made with the technique.

Rings were created with similar methods but using smaller diameter of culm being 5 cms. The detailing aspect was kept in mind while working with the loops for the consistency in the shape, the edge to edge joinary, and the overall surface finish which enhanced the value perception of the loop forms created.

After achieving the loop forms, the forms were stacked on top of each other parallelly to check the height and the feasibility of any of the multiple orientations visualised.

390

National Institute of Design

Graduation Project Doc.

The loops stacked together parallelly had an interesting linear language which either directed the eyes linearly or diagonally if the loops were seen from another perspective.

This form and pattern aspect was interesting and while stacking the loops, three loops stacked on top of each other seemed visually balanced.and were intuitively thought to balance the whole form with good center of gravity to keep the whole form from toppling.

The visualisations were done to understand the visual weight of the loops and how the base unit which will accommodate the light source can be manipulated, in order to balance the form visually. The base unit was kept slightly tapered on either side and the orientation were checked for visual balance. The third object was oriented in alternate angles to check for visual interest.

Eventually looking at all the three forms, the first one with parallel orientation of loops and upwards taper was chosen to be taken forward for prototyping.

The base was created using a node section taken from the basel segment which was measured and cut on the round saw machine, exactly at the knot point. The

Creating base

other point was crosscut at the length of 6-7 cm next to the knot to obtain a cavity which could accommodate a bulb holder of an close to 3 cm dia.

Marking drill points using rudimentary jig Once the base was obtained, a pattern for jig was made on Adobe Illustrator which was a pentagon shape with points marked on it at equal distance of 3 cm which were supposed to accommodate the brass wire protuding from the other units at equal distance of 3 cms.

Components The components for the base were the node portion,a conducting cable and a holder which needed to go into the cavity and accommodate a bulb.

To check how the light is falling on the inner and other surfaces of loops stacked on top of the other, a low watt threaded blub was inserted into the holder and the wires were connected to the plug. The light having a warm glow yet having strong light coming directly from the filament illuminated the interior of the loops quite well and looked interesting visually.

The play of stark highlights, midtones and shadows on the interiors seemed to fit well just with loops stacked on top of each other and the thought of not including the convex polygon seemed interesting as the persepctive of the concentric harmony from top created another interesting visual drama.

Further, jigs were developed to create structural supports like the previous lighting prototype utilising brass wires. The brass wires were explored by bending the wires manually using plyer.

Later two jigs was developed by using the bent wires as stencil, kept on pieces of MDF. On these pieces, bamboo sticks were inserted into cavities made by drilling points were the jig was used as a bending support and glued for stiffening the sticks inserted.

The wires were then bent by holding the jig and bending the wires along the radii using pressure to curve the wires, creating consistency between the pieces.

To correct the deviation of the brass wire fixtures, the pieces were hammered on soft board. Excess length was cut and pieces were tried for insertion.

Making the holder While doing primary study of different kinds of holder and fixtures in the market, a variety of material and lighting types were come across. One such lighting fixture/holder was the one made from ceramic and looked interesting from material, proportion and usability persepctive.

The holder had an interesting off white colour which which was thought to go in harmony with its neutral tonality and with the natural colour of bamboo in a collaborative combination of material. The form and proportion of the light holder was apt for resting in polygon cavities and was seen as a good opportunity to use this as a DIY fixture.

To understand more about this collaboration of material and understand the

Seating product prototype While looking at the various possibilites of arranging the shapes from crossections of the material and deriving utilitarian contexts for objects which could be worked upon, one such idea was that of creating seating and table for the space.

Looking at the possibilites and contextualising the ideas into the space as spatial elements, various ideas were explored.

Initially, various shapes and tessalated patterns were looked into with the objective of finding a shape that best fitted into the criteria of These criterias were for referencing the output required to match the intended needs for the tourist market.The formation of pattern also considered the amount of material required for developing the prototypes and looking for production feasibility.

Portability Visual balance Usability Tangibility Material usage

The explorations had shown various possibilites towards contextualising, but the task was to select a pattern which could be contextualised to the defined parameters and checked for the feasibility in terms of prototyping.

From the derived patterns, few patterns were chosen and analysed from the defined parameters and also checked from material usage perspective give the constraint that the units for these were supposed to be cross-cut from basal segment which has a limitation of 4-5 internodes in bambusa bamboo species.

And while looking at the various shapes, a pattern making a geometric trangular shape and the previously explored was chosen for its visual balance,repeatation of shapes from various orientations and a cohasivity in terms of one unit to the other.

The pattern was later analysed towards its consistancy from different orientations.

The selected concepts were later contextualised towards a seating and a table prototype and also looked at it from spatial and feasibility point of view.

The shapes could be repeated due to geometric form which was thought as a postitive aspect in terms of protability of the form.

The pattern when juxtaposed from both direction showed potential towards the stackability aspect.

To validate if the material could be manipulated, arranged and glued to create a durable surface, an initial trial was done with a trangular shaped form with the usage of hollow bamboo of lesser diameter of 5cm.

The form was an investigation towards the usage of material, form perception, proportions and stiffness of the joinary and the structure.

After following the processes carried out with other prototypes, the surface obtained was analysed to be feasible enough to be carried out for a scale up form.

406

The next step was to take the understanding from the previous surface based form generated and seek for a seating as an initial idea to take forward and validate it through processes.

While looking at the form, it was realised that in terms of spatial context, the form as a seating, could be contexualised into a stool which could be made collapsible and utilised for space saving in terms of transportation and which could also be a good value proposition when targetting the touristic market.

Some priliminary studies of seating concepts were carried out in cafeteria space to understand the dimensions in the specific context.

Development of Stool prototype

4.5 cm

The form was analysed to have various factors into consideration as the development took place. These factors determined that the form had to be flat pack in order to be portable and cater to touristic market as the same time not compromise on the durability aspect.

The raw material required for the form had to have bigger diameter in order to create a surface with efficient usage of material and processing tools. Thus, by mapping the surface on software, and beacause of the geometrical nature of the shapes, the dimensions of individual units as well as the the surface dimension required was calculated.

The seating units were conceptualised towards acquire this orientation at the restaurent while packing to store the seating inside,at the time of closing the restaurent or for falt packing when not transporting or carrying..

Sourcing raw material

Processing raw material

The raw material for the stool prototype was procured from a timber and bamboo mart from Narol in ahmedabad.

The mart procured the material from Assam as the cost of bamboo was low, as validated from secondary research. The poles were cut at the spot of seven feet size for transporting it to the institute.

The material was then taken to workshop and cut with the intended height of culm which was later supposed to be made into a seating.

Checking for surface viability The jigs were placed on the round crosscut culms obtained and checked for surface area available for manipulation, and also checked for the availability of the inner and outer diameter for the technique to work.

Splitting

The units were then split with a chisel tool. The fibres having a slight twist due to the structural fiber growth pattern,which made it difficult to obtain accurate 90 degrees split.

Due to this factor, there was a minor allowence provided for error correction and obtaining consistent ninety degree angles.

The blocks obtained were then spread on a sheet of paper, and arranged into a grid. once the formation was finalised, the sides of the units,step by step were applied with araldite adhesive, and pressed against one another and tied around with masking tape for the units to get stuck to each other tighter and better.

The pieces were removed from the stuck paper and sanded on the sander machine till the surface become even.

It took about an hour of sanding for the surface to become even.The sanding was done while constantly rotating the slightly larger surface on the sander belt for all the pieces to get sanded evenly and achieve a flat surface.

The shapes were later reinforced with bamboo sticks by drilling from the inner walls and inserting the sticks apllied with adhesive and left for drying completely for a day.

Turning culm to create legs

The legs for the stool were measured and appropriate bamboo culms with nodes on both sides were crosscut and fixed on lathe tool. The culms were then rounded and material was removed to achieve a rough diameter of atleast 4 cm.

2�

According to the thickness obtained from the cross cutting of the knot pieces, the 3 and the 4th node crosscuts were chosen as they provided a cavity of approx. 1/1.5 "(4/5 cms) which were supposed to accommodate the legs into the cavity and take the weight.

As the prototype was determined to be collapsible, the legs of the proposed prototype stool, had to come off from the surface and again lock back into the female joint of node unit as a dovel.In order for the legs to get locked into a point, bamboo pegs were created by turing solid bamboo pieces on lathe. To standardise the step, jigs were created for obtaining the pegs accurately.

The task was also to provide an allowence for the leg dovel to fit the node cavity as well as be loose enough for the legs to come off if made to collapse.

Analysis of Stool prototype developed Once the stool surface was developed and the legs were inserted into the node section to understand the structure, durability of joinary and feasibility of the idea, the task was to analyse the inferences from the observations made my performing a usability study by sitting on it, and understand the natural movements and orientations of the user who would be sitting on it in a real life scenario.

The first observation made in form of insights was the movement of legs accomodated within the cavity of the nodes which was not the intended aspect of the joinary.

The other observation was the shear movement occuring on the surface structure as the person sitting on the seating could move or orient themselves towards any direction, putting stress on the individual units stuck together. The other observation made was, the stools seen at various places generally were observed to have a taper which resulted towards better stability and balance. But being a restriction of the technique and the constraints of the usage of material in a certain manner, other solutions were thought and proposed to resolve the problem.

To counter this issue, a frame structure was ideated which could resolve the issues of keep the legs at their positions at the same time prevent the shear occuring on the surface structure.

Support frame development To create the support between the legs, an intervention of a frame needed to take place, which could resolve the issue of the legs moving inwards or outwards with the weight being exerted on the surface and on the legs and also prevent the shear between the individual units to occur.

For this, concepts were ideated with the intention of resolving the structural issues.

While looking at various aspects of the support structure, from adding a functional &structural value to the usage of material,all these aspects were considered and discussed with the guide.

Studying structure based examples of stool concepts While looking at the structure, some examples from secondary research were examined to understand and observe the structural inteventions which have already taken place or had form associative effinities towards the product intervention being done.

Looking at all the three legged stool concepts from the data gathered, it was very apperent that majority of prototypes either had a taper towards the seat of the stool and were also fixed permanently on it to make the whole structure strong and resistant to different types of vertical and tangential pressure exerted on it.

The other aspect observed was that the support was connected from the seat and relayed towards the whole form from the legs to a centre point where all the connecting points of the legs were held in place.

The above insights were unsed as a validation of working on a prototype of the support structure to seek for stability with the exploratory seating and look at the feasibility aspect of the concept.

Support structure by fixing bamboo culm and sticks

From the understanding for existing concepts, the ideated concepts for further clarity was analysed from the perspective of structure, form cohasiveness, clarity in language in terms of usability perception and aiding in portability aspect and positioning towards tourist market.

By looking at the various possibilities visualised for creating the support frame/structure, a very basic structure was chosen to test the concept and seek for validations towards stability of the structure.

Frame structure development To create the frame structure, the material chosen was mild steel and would utilise metal rings

To create the frame, a geometric pattern of actual size was made on Adobe illustrator and based on the measurements of the diameter of culm used for the legs, the relative distance of the culms from the center was measured to get an estimate.

Knot Unit 5.2 cm

13 cm

Through this a jig frame pattern was made which was later printed on A3 paper with the print marking of placing wood blocks for angle consistency and dotted marks for the placement of mild steel rings.

The printed jig was later pasted on an MDF block. For angle consistency, wood blocks were pasted on the specified positions.

MS rods of 8 mm diameter and larger length was taken and cut equally into three pieces of 13.5 cm length. The .5cm was taken as an allowence, as the welding at center point would consume some material towards the center.

By appropriating the visual distance and discussing the placement of frame vertically with the guide, it was decided to orient the frame, slightly below the geometric center at 17.5 cm height.

After fixing the height, the points were marked on the culm and a cavity was made on the culm surface.The cavity was then fixed with bamboo sticks to act as a stopper. This was perceieved to hold the frame to at the specific point and hold the legs firm at one place.

Retrospect The holistic process followed while carrying out the design project, generated a multitude of understandings as the project progressed.

The initial work of making the proposal, clarified the various focuses, scopes and research intents on the basis of which the project started developing through various levels of investigation from the craftspeople, material, organisational context and understanding the system and its various linkages from macro perspective.

The understandings developed at the institute within various modules was realised from time to time while doing primary as well as secondary research either on field or while generating validated knowledge though online materials, books and research articles.

The understanding of material, processes and manipulation module was a crucial aspect of this project as the very idea of taking the project was to work with the material, understand its properties and see of various interventions in terms of taking product development directions. These understandings also broadened the perspective towards understanding material from various perspectives and by framing contexts how newer understandings could be generated for oneself.

The aspect of playing with the properties of the material and deriving understanding, helped in directing project towards finding potential directions that were not ventured before. The consistent efforts towards observation and documentation of the material manipulation by the craftspeople and understanding the various details regarding the form -informing phenomenon was also realised through the activities and visits made during craft documentation module. The learnings from craft documentation module helped towards minute observations and

systematic enquiry of skills, processes and methods adopted by artisans and how by the documentation of these methods a thread of insights could be gathered, was also another aspect of realisation from the module. It was realised that, it was important to document the minute aspects to derive meaningful insights about the interaction of material and craftsperson in order to have holistic understanding of the organisational structure and its implication towards behavioural aspects of the craftspeople.

The understanding of form and emotion provided the insights towards the investigation, by what means intangible attributes can be given tangible forms and while doing material manipulation and creating forms, the realisation of utilising this understanding to create forms that depict those attributes was realised.

The learnings generated from form and culture module provided the insights from time to time, towards the investigation of the various aspects of material interaction of craftspeople, organisation and the natural and social setting and how it informed the system and its elements at large.

Understanding developed during system design module helped in forming the structure of the project and the various linkages I was supposed to touch upon.looking at the system at large and understanding the craftspeople, the organisation, their organisational structure, usage of material and the interconnections between these played a crucial role in advancing in each step of the design process.

The timely interaction with guide and feedback sessions broadened the understandings of the subject and its various constituents, which were either been overlooked or not being thought of.

The various contexts and frameworks from writing the proposal to defining

the project towards the aspect of utilising various tools for further investigation and still going back and froth in the process was also a meaningful insight shared during the interaction with the guide, which shaped the project in a broader and clearer manner.

The interaction with people in this domain provided the realisation of current challenges, potentials and opportunities which lies within the hands of all stakeholders and how everyone of them had an equal contribution towards the livelihood enhancement of the tribal community and not just the selling aspects of the products.

Through the material interaction and by studying about the material from various research materials, sources and secondary information, a rich understanding was generated which helped towards realising the potential of the material in local, domestic and international context.

From the project direction and learning perspective, the project direction with the progressing development took an exploratory approach to find newer ways to look and approach the material and product development context. It was also realised that the skill development training imparted to the tribal community was fairly new for them to adopt as these skills were very different from their existing traditional skillset of interlacing the material and making utilitarian products for local context and consumption. These new skills provided and informed them of newer ways to create high value perceived products which were being catered to urban market. This insight of the coexistence of newer skill sets with their existing traditional techniques informed towards the possibilities of adopting exploratory methods for product

creation which was realised to be linked with the livelihood development aspect of the tribals working within the framework of the organisation.

The exploratory method which was adopted at each level of context development towards the product categories was realised to be an essential focus in terms of newer knowledge creation in bamboo manipulation and its perception.This methodology was also a key towards the perception change required while looking at product development and product positioning towards contemporary market.

Being new in the context of bamboo as a material and domain, the understandings developed by looking at various ways of manipulating the material and especially investigating the transverse manipulation and the potential the direction held, gave an important insight towards the potential the material had in terms of knowledge creation of newer kind and how this aspect could be utilised and focused towards livelihood generation through the product development initiative within the organisational and cluster was realised.

This was also realised to modify the crafting process of the material to suit the contemporary needs of the markets, which could enhance the perceived value of the material and bring newness to the project, by creation of newer skillset.

Thus the product development was dealt with three different levels of creation of skills, knowledge and product through the utilisation of same material.

Design Critic & Further recommendations The further scope of the project was supposed to seek for production of the feasible product prototypes and also look at the aspect of looking at marketing channels, to which the production could be targetted towards.

The aspect of cluster based product development outside the organisational structure was also considered as a key aspect of taking the project forwards and working on the livelihood development aspect within the kotwaila community.

As the project required fairly new skillset in terms of unit processes, the consideration of standardisation and efficiency of product was determined with the development of better tools which could reduce the time and efforts involved in processing the material and also reduce the drudgery in the process of product development.

The aspect of creating an identity of such an exploratory method of manipulation with the tribal community was also considered for future development.

The few shortcomings of the project in terms of certain product development issues were also considered to be looked into deeply for resolution and making the products feasible and durable to imapct the value perception of the material in contemporary market.

Production Challenges To improve design and quality control, design inputs needed to be provided for product development assistance from the beginning of value chain ensuring product matches preferences of the urban market. These point were highlighted towards the unit processes which specially had to look at the below components for quality control and standardisation.
