Preface
The UG course Graduation project, at GLS Institute of Design, was made under the guidance and supervision of Story Design, one of the leading design companies in India. Story Design is the forefront organization, which believes in unfolding complex challenges. With years of experience in Industrial Design and Branding, they have curated landmark epitomes in the industry. The design team put together a tailor-made design process based on knowledge achieved from lectures and literature studies, and experience from working with the design process to best accomplish the assignment. The problem was to study the product market, understand what works, ideate, and suggest options for implementation a ceiling fan but then with further user validation,I addressed the problem for an innovative and a visionary result. I started with a short initial brainstorming before I moved into the analysis and research phase, where I performed a thorough examination of the company, the market, the product, the user, colors and materials, trends, etc.
A survey was composed of both people who own a ceiling fan and people who do not. They bought the fan for its functionality but did not think that their fan was particularly aesthetically attractive. But still after getting insights surveys and insights were taken from the users for better feedback. Sketching and idea generation was a great part of the project. A huge amount of ideas and concepts were evaluated with several methods and refined to finally result in one concept. The final conceptual ceiling fan includes functions, aesthetically aspects, construction issues, light technologies, etc. The concept also includes a vision for the control system (a remote and a smart home app) and the packaging.

Design Brief
“A breakthorugh design of ceiling fan which would bring a major shift in existing ceiling fan industry to ameliorate lifestyle of people using it.�
Ceiling fan has not seen major shift in Indian market. There have been a lot of effort on improving the aesthetics and finish. However new technology has found less application. Some new technological advancements have been made inroads in the market but not found major success. The student is expected to study product market, understand what works, ideate and suggest options for implementation.
21
Objectives The objective of the thesis project is to design and develop a ceiling fan that is adapted to the market’s desires, needs, demands both in functions and esthetics. The project will include and require several different areas of knowledge that the student has obtained during their bachelor studies. The project will include the whole product development cycle; brainstorming, ideation sketching, surveys, interviews, semantics, ergonomics, refining, construction and CAD, material knowledge and presentation layout, etc. The student will perform a background analysis of the company, placement on the market, target groups, users, colors and materials, trends, etc. This knowlwdge will guide them through the decision making and later on backing up their final results.

The design process
GENESIS
RESEARCH
ANALYSE
The design process for my project is more or less linear in naturestage wise and chronologically. The genesis of the project was when I first received the brief. Informal discussions and observations started from the very beginning and although casual in nature, these played an important part throughout the project. Then I did primary and secondary research, which was more focused during (but not restricted to the initial phase of the project. The research ranged from a study of the history of fan to the CMF of the product.
IDEATE
USER VALIDATION
OUTPUT
Then came the analysis of collected data and its proper synthesis, which helped me to concentrate my findings and narrow down the scope of work-in terms of the product category and the user persona-not in terms of technology and usability. Having had enough understanding of the problem at hand, I gradually moved towards the concept generation and ideation phase. After generating a few concepts, we validated these concepts with real end users-across two major cities in the country: Mumbai and Delhi -to further refine the product and make it more market ready. The project ended with a tangible deliverable, and a promise to develop it before the competition does.

India Air pollution and impact on health in India As one of the world’s most populous countries, India too has seen a significant rise in incidence of respiratory diseases such as asthma and COPD over the last decade. The burden of COPD in India has been estimated to be about 15 million cases (males and females contributing to 9.02 and 5.75 million, respectively), causing about 500,000 deaths per year. The actual numbers are, however expected to be much higher. Most epidemiological studies in India have been based on respiratory symptom questionnaire. Use of spirometry to define COPD has shown a two-fold higher prevalence of COPD. India has 20-28 million asthmatics, with a prevalence of 10-15% among children, aged 5-11 years. Indian study on epidemiology of asthma, respiratory symptoms and chronic bronchitis in adults (INSEARCH), a landmark epidemiological study conducted by the Indian Council of Medical Research (ICMR) found the overall prevalence of asthma and chronic bronchitis to be 2.05% (adults aged ≥15 years) and 3.49% (adults aged ≥35 years), respectively. The national burden of asthma and chronic bronchitis in this study was estimated at 17.23 and 14.84 million, respectively. [5]

Climate of Delhi Air pollution levels in Delhi and most other North Indian cities remains at hazardous levels. The level of PM 2.5 or particulate matter at the size of 2.5 microns — which is very, very small in size and easily settles in our lungs to cause breathing difficulties and other illness. 1. Crop Burning in Punjab, Haryana and Uttar Pradesh is the major reason for increase in air pollution level. 2. Pollution from Carbon Fuels: The air quality index has reached ‘severe’ levels. 3. Onset of Winters: pollutants in the air become unable to move and result in smog.
5. Pollution in Delhi
4. Industrial pollution also increasing air pollution and building-up smog in the air. 5. Despite the ban on cracker sales Residual Pollutants from Diwali, contributed to its build up. [6]

Climate of Mumbai A recent report by the World Health Organisation ranked Mumbai as the fourth most-polluted mega city of the world. “Heat, dust, all this causes increase in particulate matter in environment and thereby increasing diseases in children and adults primarily due to dust and toxic gases. The only solution left for people in Mumbai is to start wearing masks and using air purifiers wherever can. Air purifiers are the next home furniture.� [7]

Fan WHAT IS A FAN?
7. Sweat of a human
Process of evaporation from a human skin
A fan is a device used to create flow within a fluid-typically air. It is either human or mechanically powered.
When humans sweat, the tiny droplets of salty water that accumulate on the skin start evaporating.
While most people associate fans with cooling, they do not actually cool the air. Instead, the cooling sensation is experienced through a phenomenon called evaporative cooling.
The fan forces air into circulation and part of this air hits the surface of the skin. This causes heat to transfer from the tiny salty water droplets (sweat) to the air. This is what makes us feel “cool�, and fan is an efficient way of cooling, [8]
37
HISTORY TIMELINE
38
500 BCE, punkha fan was used in India. Handheld fan made from bamboo strips. [9]
8th century, the Chinese applied hydraulic power to rotate the fan wheels for air conditioning. [10]
17th century, English architect Sir Christopher Wren used bellows to circulate air as a ventilisation system [11]
2009, James Dyson first creates the airmultiplier technology. [20]
1998, Walter Boyd invented the HVLS fan (High Volume, Low Speed) to cool cattle. [19]
1981, Toshiba (Japan) granted a patent for a bladeless desktop fan. [18]
1851, Reid installs 4 steam powered fans in the ceiling to force incoming air upward through the vents. [12]
1882, Philip Doehl developed the world’s first electric ceiling fan. [13]
1920, Japanese company mass produced electric fans for home use. [14]
1970s, with increased awareness about energy efficiency, ceiling fans made a major come back. [17]
1960s, with the advent of air conditioning systems, companies discontinued production of fans. [16]
1940s, Crompton Greaves, India became world’s largest manufacturer of electric ceiling fans. [15]

TYPE OF AIR AND HUMAN COMFORT?
10. Relative Humidity
9. Cooling air
The type of air can be classified as: cold and dry air, hot and dry air, and humid air. As we have seen before, in “how the fan works�-in order for the fan to provide us comfort, we should sweat and that sweat should evaporate from the body. [21]
In humid climate (e.g. South-West, and South-East India), we find skin to be sticky. This is because the air contains moisture which accumulates on the human body-instead of evaporating from it. This is also the same reason why a cool breeze of air on a hot summer day seems so pleasant. [22]

Airflow AIRFLOW

Individuals perception of comfort or discomfort
Airflow is the movement of air from one area to another, courtesy of the existence of pressure gradients. Air naturally flows from areas of high pressure to low pressure. Apart from natural causes, artificial means such as electrical or manual fans are used to induce a pressure difference to generate airflow. Like any fluid, air exhibits both laminar and turbulent flow patterns. Laminar flow is when air flows smoothly, meaning the direction of flow and velocity are uniform. Turbulent flow occurs when there is an irregularity or interruption in the flow passage. The direction and velocity are non uniform in a turbulent flow.
When it comes to the layman, airflow is an important factor to determine the occupants’ thermal comfort. Varying rates of air movement may positively or negatively impact individuals’ perception of warmth or coolness, and hence their comfort. The interaction of air velocity, type of flow, air temperature, humidity, radiant temperature or surrounding objects, and skin conductivity result in particular thermal sensations.[23]
41
HOW A FAN CREATES AIR FLOW?
Fan’s serving purpose depends in which direction it is rotated. 11. Air flow of fan
The fan can be rotated in two directions (clockwise and counterclockwise). How well it serves its purpose depends on which way it is rotated and whether the blades are designed to complement the direction of rotation (more on that later). For the sake of simplicity, let us consider the ceiling fan rotating in clockwise direction inside a typical room setup (refer diagram).
42
When the fan starts rotating, a low pressure zone is created above the fan. This causes surrounding air to be pulled in from the top of the fan and thrown out from the bottom of the fan with higher pressure. This thrown air pulls the surrounding air along with it, thus generating a bigger airflow (like an avalanche effect). The airflow velocity increases as we move away from the fan center.
12. Ideal air flow in summer
The air in circulation hits the floor, side walls, and any other obstacle and is reflected in various directions, thus we experience airflow from not just one single direction. This airflow is measured in CFM: Cubic-feet per minute. Now, if we rotate the fan in reverse i.e counterclockwise direction, the arrows in the diagram will get reversed and the fan will start sucking air from underneath it (the room) and throw it out towards the ceiling.
13. Ideal air flow in winter
Many fans in western countries come with this provision to rotate the fans in either direction depending on the season. The counterclockwise rotation helps during winter as cool air is sucked in from the room and thrown towards the ceiling, thus forcing the warm air which has risen to be thrown outward and circulated across the room. [24]
43
MOVEMENT OF AIR ON SEA COAST
14. Movement of air on sea coast
Temperature differences at the Earth’s surface occur wherever there are differences in surface substances. A dark tarmacked surface will heat up more quickly on a sunny day (i.e. absorb more solar radiation) than a grassy field. Similarly, along the coast, large areas of land heat up more quickly than adjacent sea water (water has a large heat capacity and is a good conductor of heat). Air near the land surface is heated by radiation and conduction, expands and begins to rise, being lighter than the surrounding air. This is convection. To replace the rising air, cooler air is drawn in from the surface of the sea.
44
This is advection, called a sea breeze, and can offer a pleasant cooling influence on hot summer afternoons when further inland the heat may become oppressive. Air above the sea sinks and is again pulled in over the land. The full sea breeze circulation is show in Figure 3.2. A very hot summer sun may cause a sea breeze of up to 15 mph along the coast, felt in decreasing strength 20 to 25 miles inland. [25]

Design parameters
BLADE SELECTION The aerofoil shape is an ideal section for fan blade design. The optimum shape is arrived at on the basis of high efficiency-high lift, low drag, and the life coefficient. The blade section works in tandem with the blade shape and angle. Its efficiency and performance is a result of the material, motor power and rpm. Most metal blade fans that we see in India use extruded sheet metal blades that have little to do with blade section. This is because they are most cost effective.
25. Blade Selection
52
While most customers today that go out buying fans would probably be looking at factors like price, color, and warranty before making a decision, these things are seldom related to how well the fan performs and is able to provide comfort. Many companies these days provide data like RPM (Rotations per Minute) and CFM (Cubic Feet per Minute) of a fan. While these are good marketing tactics, it does little in educating the customer about what drives these numbers. Lets have a look at a few of these design parameters which determine a fan’s effectiveness [40]
HUB SIZE
BLADE SHAPE
26. Hub size
27. Blade Shape
The hub is the part of the fan where blades end and the motor is fitted inside. The hub serves some major functions. It allows termination of blades at a point where they would cease to function efficiently and it prevents back flow of air through the center. It also serves as a structural piece connecting the blades and imparting rotation to them. A hub must be large enough to pick up from where the blades are no longer able to carry the load. The blade speed decreases as we move towards the center. This reduction in the speed of the blade section reduces potential work that can be carried out by the blade. Thus accommodating more blade width and increased blade angle. [40]
One of the most important requirements of a fan is that it must impart-to the air stream-a uniform velocity and pressure over the entire area (from center hub to blade tip). For this it should have two characteristics: The individual blades should be narrow at the tip and widen towards the center. The tip is where the blade velocity is maximum. As we reach toward the hub, more blade width is required as there is lower blade velocity. [40]
53
BLADE ANGLE
28. Blade angle
29. Blade angle of oars
Blade angle is the angle of the blade with the plane of the rotation at a given point on the blade. It usually varies from the hub to the tip of the blade. It is important to note that, for uniform flow and constant pitch, every point on the blade, from hub to the tip, must have a different angle.
For further understanding, imagine the fan blades as oars of a rowboat. Rowing the boat with oars would require the oars to be slightly tilted or slanted. If the blades are completely parallel to their plane of rotation, they will cause very little movement. Conversely, if the blades are tilted to steeper angles (as we go towards normal) to the plane of rotation, they will face huge amounts of drag and can even bend beyond a certain point.
You might have noticed that the blades of a fan are slightly curved and tilted at an angle. This angle is called the blade angle. This is one of the key factors that affects how much air a ceiling fan can move. [40]
54
Increasing blade angle causes more airflow, but it also requires a more powerful motor as compared to blade with no pitch. This is the reason why most commercial fans have a blade angle of around 10-16 degrees near the tip. [40]

Fan components teardown
Comparatively, the construction and working of a ceiling fan is not that complex. Most conventional ceiling fans made in India are direct-drive ceiling fans. These types of fans employ a motor with a stationary inner core (stator) and a rotor to which the outer shell is attached (also called motor housing). Fan blades are attached to the motor housing through flanges. The whole setup is mounted on the ceiling through a ceiling mount mechanism and a down-rod. Here, each component is introduced in little more detail. It also helped get an idea of the scale of the product like certain dimensions which are standard to the company’s processes eg. the dimensions of the motor.
To further develop understanding of the construction of a ceiling fan, Teardown of 2 different models of fans was done. •
One fan has the common sheet metal blades.
•
The fan is a plastic blade fan with aerodynamic profile blades.
Taking apart the fans increased understanding of different components of fan. Every component has a specific purpose and the use of materials and its design are refined to the most optimum level so as to reduce cost and increase efficiency.
Teardown later became useful while sketching the concepts, as it gave clarity on the construction of a ceiling fan.

When I was concluding my research, I was presented with an internal study carried out by Story Design -�Market Understanding of fans�. Although their study was carried out by the marketing and sales team, the quantitative data gave some valuable insights about the market size and consumer mindset. This chapter carries a combination of some data from that presentation with data collected from the user interviews. The study was carried out pan India and the statistics backed my data from local research.
Fans fall under the Small Domestic Appliances category along with electric irons, water heaters, water and air purifiers etc. As is the case with most domestic appliances, the fan market in India is showing consistent growth numbers both in terms of unit sales and value growth. Ceiling fans is the biggest sub category accounting for almost 65% share of unit sales. Considering the Indian demographic and the fact that majority of population lives in rural India-unit wise-sub economic range enjoys a maximum share of the market.
65
COMPETITION MARKET As there are many companies in the fan industry, this research helped me evaluate their products from the end users’ point of view. The fan industry in India is over INR 6000 crore and there are many players in the market. While there is enough competition among major established companies, the unorganized sector is as big as the organized sector especially in rural areas. However, here in this section I will only take into account competition among the established companies. These companies have been in this business for at least fifty years. Hence, they already have a strong understanding of the Indian consumer mindset. Their fan models, choice of colors, introduction of new technology all are decisions made by these companies after thorough research on the field. A note of popular models from these brands, few of their key technical specifications, and went through a few customer reviews of these models on E-commerce platforms. This gave an idea of how the product is received by the people. It also helped me to identify a few gaps in the market.

•
“premium” products – defined as those that cost at least 20% more than the average category price
•
“premium,” a majority (54%) of respondents from around the world cited its production with high-quality materials or ingredients, while another 46% pointed to it offering superior function or performance.
•
By contrast, fewer than one-third (31%) said that a “premium” product is defined by its being expensive. Instead, attributes such as the product having a superior design (38%), coming from a well-known or trusted brand (38%) and offering or doing something no other product provides (37%) are more likely to be associated with the term “premium.”
•
Premium products have emotional resonance with consumers, per the survey’s results, relating primarily to self-esteem and perceptions/status. For example, around half of more say that buying premium products makes them feel good (52%) and confident (50%), while more than 4 in 10 also note that buying premium products shows other people that they have good taste (45%) and are successful (41%).

Analysis FORM ANALYSIS
Although the form and design of a ceiling fan is more or less similar at least in terms of arrangement of blades and motor hub-there are slight variations which can be observed. 39. Fans for form analysis
72
This analysis was helpful in making me put some noteworthy fans on one page and observing from a distance with the eyes of a consumer.
Certain elements of different models-like the shape of blade, design of shank, the bottom cover of motor hub, canopy design, color and
use of chrome-were noted and ultimately helped shape the end concept. 40. Fans for form analysis

FINISH AND COLOUR ANALYSIS Ceiling Fans come in a variety of finishes and colors. Here you can select the overall color category which can suit your application and match your room exactly. From the top three most popular finish types: Bronze, White, and Brushed Silvers to unique colors and types such as chrome / polished silver, novelty and children ceiling fans, to everything in between.
BRONZE Ceiling Fans are perfect for matching your ceiling fan to dark woods and furniture which is perfect for both indoor and outdoor environments. Many specific finishes fall within the bronze category such as Oil-Rubbed Bronze, Brushed Cocoa, New Bronze, Distressed Bronze, Resoration Bronze, Bronze Accent. Every manufacturer carries multiple styles of bronze and here it can help you.
WHITE Ceiling Fans are prefect for blending into white ceilings and not becoming a focal point in your room. Also with white ceiling fans you automatically get a sense of cleanliness with a modern contemporary feel. There are multiple types of white ceiling fans ranging from architectural white, classic white, summer white, matte white, and appliance white.

Stakeholder mapping The ceiling fan is fairly a simple product. The main stakeholder is definitely the end user. But before it reaches the end user, there are many more involved. Like the media (print and digital), the main distributor, the authorized retailer, showrooms, sales staff, the local hardware store, online sales portals, service person etc. The design of the final concept should try to address as many stakeholders as possible and not just the end user. When it comes to the end user, there are many possibilities, and they each have a different requirement depending on their age, routine, and lifestyle. Assuming a patriarchal society, the majority of women in India spend their time indoors making them the main beneficiary of a ceiling fan. Males spend less time at home, but demand a fan to provide them comfort when in use. Infants are the sensitive ones and require fans to run at slow speeds. Even as the demographics change, the stakeholders and the intended use of a fan changes. A fan might be the primary source of providing comfort to rural areas, whereas urban homes have air conditioners to do the job, in which case fan becomes a secondary source of comfort. Stakeholder mapping thus became useful to keep track of different parties involved in the ceiling fan ecosystem.

INSIGHTS
•
Before I started with market research, I had a fairly decent understanding of the fan (evolution of fan, its design parameters, and what is available globally). But this secondary research did little in helping me understand the user’s side of the product.
•
For this I had to go out into the market and talk to people-its first hand users. I was certain that this product is not something that they heard about for the first time, which is why my interview structure was pretty straight forward. The whole idea was to get an understanding of the people’s perception of a “fan”. Which fans they use the most and in what conditions. Their usage patterns. Whether they are satisfied with their current fans or they would like to make any changes. All this would help me gain insights of what the customer is looking for and whether these demands are being satisfied with the fans available in the market, or is there a clear gap in the market which needs to be addressed.
•
By the end of these interviews, I could clearly see that the ceiling fan holds a much deeper purpose, of family time and watching TV. Without the ceiling fan, it is hard to imagine a modern home in India.
•
Which fans they use the most and in what conditions. Their usage patterns. Whether they are satisfied with their current fans or they would like to make any changes. As most of the people whose interview was taken were from Delhi, a common thing noticed was that they all were very society status conscious. One common appliance used in their home was an air purifier.

Life cycle analysis
Exhaust and ceiling fans are estimated to typically last for a maximum of 10 years. These estimations are of course dependent on the quality of the fan you have and the frequency of its usage. If you have a Hunter ceiling fan then it will last a lot longer due to it’s very high build quality and the Lifetime Warranty provided which is pretty unique in the market. Good quality fan really costs more than those cheaper ones but sometimes, the most expensive ones have more or less the same quality with those at average prices. The price differences can be indicative of several other factors such as deliver, warranty services, consultation, and the popularity. Now let’s go to the issue of the frequency of usage. Begin assessing by answering the following questions: • How many hours a day do you have your ceiling fan turned on? (on average) • How many hours do you turn it off? (approximate)
These are two simple questions that will tell you a lot. Obviously, a fan that is used more frequently has greater tendency of wearing out first, given that both undergo regular cleaning and maintenance. Knowing how much workload you give to your fan will tell you if the diminishing satisfaction you receive from it is a product of old age or technical issues. So a consumer cannot identify a good quality fan. The only way to make them buy a perticular fan is by the brand value, aesthetics and its add on feature. After buying the fan, even if it does not give maximum output which was promise, an Indian mindset dont tend to buy a new fan before 10 years.
89
WHAT ARE THE SIGNS OF A FAN NEEDING REPLACEMENT?
43. Replacing fan
90
•
There’s no definite things to tell you that you have to replace it. But initial signs of the following deserve to be looked into:
•
Annoying buzzes that develop after a few years. This is due to either sub-standard capacitors or poor quality motor windings and laminates.
•
Wobbling – A properly installed fan should never wobble. This is a sign of an inferior hanging device or unbalanced blades.
•
Squeaky sound of the fan even after oiling.
•
Diminishing speed.
•
Recurring technical issues even after a professional fix.
Major complaints LOUD OPERATIONAL NOISE
DUST ACCUMULATION
WABBLING
UNEVENLY DISTRIBUTED AIRFLOW IN ROOM
POOR BUILD QUALITY
POOR AESTHETICS
IMPROPER SPEED SETTING
NOT BUILT TO LAST
•
What this data helped me is to take note of major things to consider while designing the new fan.
•
More than customer complaints, these act like design parameters and things that need to change in the current generation of fans.
•
Many complaints regarding the color, styling, and design of fans. (This point made me probe further into the fan aesthetics and find out what it is that consumers are looking for)
91
Customer journey Mapping Wants new fan NEW! CUSTOMER
Replace old fan
End user is the main stakeholder of the ceiling fan. Oftentimes the end user is different than the customer who buys the fan. There are mainly two scenarios under which the purchase of a fan can be classified: either the customer wants to buy a new fan, or a customer has to replace an old fan (out of various reasons).
92
TV Media, commercials
Research online/ In store
In either case, the hunt for buying a new fan begins. Among many influencers, TV commercials and word of mouth are dominant. The consumer nen starts his/her research online or by visiting local stores or asking friends or relatives about their most recent fan purchase.
STORE CUSTOMER 1 CUSTOMER 2 Open to new Specific things bujget/brand
Visits store
BUYS ONLINE AFTER CHECKING REVIEW
Then based on their personality, if they are willing to try something new or have a specific budget/brand, they visit the store and make the purchase or buy it online. In case of a store visit, the sales staff plays a pivotal role in directing the customer towards a particular brand or model. After the purchase is made, the customer then goes home.
SALES STAFF Suggesting what to buy
CUSTOMER Buys and goes home
GOOD EXPERIENCE Suggests to others
BAD EXPERIENCE Gives bad review but keeps using anyways
The fan is usually fitted by an electrician. Based on the experience, the customer is either satisfied or not. In either case, the customer rarely thinks about changing the fan because of some inconveniences.
93
Consumer mindset about fans INNOVATION ENERGY CONSUMPTION
COLOR
AESTHETICS
WOBBLING NOISE
ROOM DECOR 94
The ceiling fan is the second most common electrical appliance in the Indian household. We once brainstormed about ceiling fans and a few keywords that are most commonly associated with ceiling fans are: energy consumption, color, wobbling noise, aesthetics, room decor etc. Internal discussions with company professionals and interviews with consumers added a few keywords to this list, but rarely was mentioned the word innovation. This is one of the key traits that is missing in the fan industry. It is almost as if the product has stopped innovating beyond new colors and decorative elements. There is also a positive side to this fact and one that I should consider before generating concepts. It is that since there is so much stereotype surrounding fans, it would be wise not to deviate too much from the conventional aesthetics of the product. People have a mental model and associations with a ceiling fan, and a good innovation would be one that would satisfy their latent needs while not deviating too much from their perception.
Changing lifestyle of people
DIGITAL CONVENIENCE
44. Healthy lifestyle of a girl
All our lives are a testament of how our lifestyle has changed over the past few years. With the technology changing so rapidly, we can expect many more changes in the coming years. More and more time is being spent indoors whether in offices or homes. More and more products and services are focused on offering convenience and making sure we do not have to leave our seats.
Digital media is taking over physical interactions and now most work can be done at the touch of our fingertips. Even in ceiling fans, in recent years, Indian companies have adopted this trend and are providing remote control to consumers as a way of managing the fan speed, turning it on/off, setting a timer etc. What new concepts I should develop, should have some part of digital convenience associated with it.
95
Degrading air quality INDOOR AIR POLLUTION
Although this is more of a social problem than an insight, this issue came to our notice when interviewed people brought it up during the meeting. Because fan is a product primarily related to air, the problem of the quality of that air seemed inevitable. Worldwide, over 80% of urban residents are exposed to air pollution levels that exceed WHO limits. More than 4 in 10 Indians are exposed to 5 times the safe limit of particulate matter in the air they breathe.
45. Indoor air quality
96
These statistics are astounding and the air quality affects every living person on this planet. The reach of this problem has come out of the newspapers and internet articles as more and more citizens themselves are addressing concern about the air they breathe. Thus, this became one of our major insights, and would later become one of the pillars of the conceptualization phase of the project.

Blooming fan
135
Aesthetically most appealing from all four of them.
From previous interviews and research I had concluded that a fan is aesthetically pleasing if there is something new about it.
The blooming fan is a breakthrough in fans design. There has nothing happened even close to similar in it.
This is no more a fan in a room. It is a decorative piece. Every room should have one or maximum two focal points. The fan will be the focal point in the room.
Though it is making a style statement of its own, Yet it is very subtle and pleasing to eyes.
As the name suggest ‘blooming’, the fan beautifully blooms which would in return bloom the room
136
137
The colours are finalised very precisely. The four colour scheme chosen are based on current trents. The colour chosen are such that atleast any one of them would go along with the interors of a room.
‘CLASSIC BLUE’ is the pantone colour of the year. ‘Sonic colour’ scheme of the fan would go well with room interiors of classis blue.
‘Mystique’ colour scheme visually expresses a new-age spiritualism with a penchant for the past. This colour of fan unites the past and the present.
Sonic colour scheme is closes to the family of classis blue but not exactly same.
This colour scheme is very common in room interiors and in large multi-purpose halls. This is a clas-sic colour which would go with any kind of interior of room.
This would create a slight contract.
138
‘Blend’ challenges the ideas of form, function, perception and bias that once restricted creativity. This is the main colour of this design. The name of the fan blooming is represented by this colour.
‘Potent’ colour scheme is best for antique theme rooms. Rooms with raw wood with transparent polish.
It is a very soothing colour. Can go well in living room. Most common interior color of grey. This fan could be a great combination it. A tingle of pink added to the interiors will create a focus point in the room. As well as it would blend well.
139
In every layer there is a slight variation in the tone of grey. This creates a very subtle blooming effect.
Only one layer is dray grey whose colour is similar to its blades.
A metallic shine paint is used as it is currently in trends for home appliances.
Illumines from center act as the primary source of light in the room.
Illumines from two strips are for aesthetics purpose. As this fan is for high segment, this liberty was given by the client.

Air Pollution
Indoor air pollution is among the top five environmental health risks. Usually the best way to address this risk is to control or eliminate the sources of pollutants and ventilate a home with clean outdoor air. But opportunities for ventilation may be limited by weather conditions or by contaminants in the outdoor air. Indeed, the rising prevalence of asthma, allergies, and COPD over the past few decades, has been attributed to an increase in environmental pollution- a price being paid for rapid industrialization, socio-economic development, urbanization, and changing lifestyles. [45]

IMPROVING INDOOR AIR POLLUTION
66. Air purifier in indoor environment
• Source control If you can completely remove the source you should not need an air purifier. The problem is this is not always possible. • Ventilation Another option is to improve ventilation in your home or work space. • Air Cleaning If source of the pollution cannot be removed, air purification is your best bet. [47]
Air Purifier WHAT IS AN AIR PURIFIER
HOW AN AIR PURIFIER REMOVES GASES?
67. Inside of an air purifier
68. Air purifier
An air purifier is a device that purifies the air of particulates or gases. There are a few different air purification technologies.
The challenge with a HEPA filter is that the gases are so small they pass right through. What works is to adsorb them through a different type of filter.
An air purifier is made up of a filter, motor/fan and housing. All have these 3 components. It circulates the air in a room and captures the particles and gases in the filters. [48]
Activated carbon has many cracks and crevices that allow it to adsorb gases. Some purifiers have a carbon pre-filter. Commonly this is a foam filter with a sprayed on carbon coating. While better than nothing, the effectiveness is limited.[49]

Air Purifier History
1823
EARLY 18TH CENTURY
1854
1940
Inventor Charles Anthony Deane patented ‘Smoke Helmet’ for firefighters.
Air pollution from coal - based industrial urges to create air purification system
John Stenhouse developed charcoal - based respirator.
HEPA filter to protect scientists in nuclear research lab during World War II.
2020 Nowadays air purifiers are becoming more efficient and smart by integrating high quality filter, air quality sensor and mobile connectivity.

High performance compact portable home air purifier marketed by IQAir.
First home air filtration system introduced by Manfred and Klaus Hammes. [50]
Types of Indoor Air Filter HEPA TECHNOLOGY
ACTIVATED CARBON TECHNOLOGY
69. HEPA filter
70. Carbon filter
The HEPA (High Efficiency Particulate Air) filter is a very fine fiberlike material that has been folded back and forth to create the shape of an accordion. This accordion shape creates a maze of randomly arranged fibers and presents a very large surface for air to be pushed through by the air purifier fan. Airflow must have an opportunity to pass through the filter in order for it to be cleaned. [51]
Activated carbon filters are comprised of many molecular sized pores that have high absorbent ability and chemical bonding. These properties make them a very effective tool for capturing pollutants such as chemical emissions, gases, tobacco smoke and odors. [52]
153
UV TECHNOLOGY
71. UV filter
A UV air purifier can convert molecules of oxygen and water found in your air into ozone and hydroxyl. The active molecules react with the air pollutants and destroy them into harmless components like water and carbon dioxide. [53]
154
Need to Replace Air Filter
72. Degrading quality of filter
There are two main reasons you should replace the filters. If the filter is clogged the air flow will be reduced. This means you are not getting filtered air changes. Another reason is that carbon filters have a life span. While carbon is great for adsorbing many gases it only does this while it has capacity. At some point the filter will release the gases it is holding. This can show up as a rotten egg smell and should be avoided. [54]

Airflow AIR FLOW OF AIR PURIFIER
AIR FLOW OF CEILING FAN
It first purifers its local atmosphere. And a loop is created due to which the purifed air only keeps on being sucked by the purifier.
After few 30 minutes when air distributes, the purifiers sucks in new batch of air.
An air purifier is always kept in the corner of a room.
cool air thrown from fan sinks down
warm air near the ground is light in weight so rises to the ceiling.
Therefore movement of fan rotates the air in a room in fast circular way.
163
AIR FLOW OF AIR PURIFIER FAN
Problem caused by a pedestial air purifer taking more time to purifeir air of whole room due to less movement of air is solved by this intervention
Air realeased by the air purifer milngles with the high pressure air of fan and is distributed throughout the room.
As seen above, fan helps in fast movement of air throught the room, therefore air sucked in by the purifier is not from it local atmosphere .
164
Air Suck In and Suck Out Direction
This direction of air sucked in and out will go againt the flow of air movement by fan.
The most apt air movement. The air filter will automatically suck in air as the air pressure created by fan is in same direction. The purified air coming out from below the purifier will mingle with the air pressure to reach every corner of the room. This direction of air movement compliments with that of fan. But linear placement of filter will reduce the amout of air sucked in a minute.

Air Filter FILTER USED PET PRIMARY FILTER - First layer Filters out large particles like hair, dust, cotton fibers
HEPA FILTER- Second layer Very fine fiber like material that has been folded back and forth. This shape creates a maze of randomly arranged fibers and presents a very large surface of air to be pushed through by the air purifier fan. They absorb pollens, pet dander, bacteria.

Benefits of Ananta An air purifier is your ceiling fan’s perfect pair. With an air purifier, you’ll reap the following benefits: •
Fresher air to breath
•
Lesser risk to respiratory issues like asthma
•
Lesser risk to allergies and skin irritation
•
Reduces the risk of kids developing irritation to dust
Getting an air purifier unit is comparable to stocking a first aid kit at home. The only difference is you use air purifiers more often (daily in fact) to prevent possible health problems while first aid kits are there to aid when something bad happens. Bottom line is, the healthier the air in your home the healthier your family members are. There’s a limit to how much your appliance can do to help you but preemption is always better than nothing.

Key Features INTAKE MESH
GOING WITH THE FLOW
PARALLEL FAN DESIGN
Faces the same airflow direction and slices it up for even circulation. Rounded sections reduce wind resistance and noise.
Even a fan blade just 1mm thick can have a significant impact on airflow, that’s why Ananta has been meticulously designed to minimize air resistance and energy loss as air flows through each section.
Both fans at the top and bottom work together in sync to provide a uniform air passage.
FAST AND STEADY
DIM AND QUIET, YOU WON’T EVEN REALIZE IT’S THERE
SENSES WITH ACCURACY
The best fans remain stable and precise even at full speed. Every fan is tested for precision and balance at high rotation speeds for the most stable performance.
Ananta is designed simply, with minimal aesthetics. The lowpower Nidec motors consume just 4.8W, which reduces noise especially on Auto mode. Just like the sound of a gentle breeze, Ananta helps you drift off to sleep.
The high-quality Japanese SHINYEI particle sensor calculates indoor PM2.5 quality and displays it on your phone.
At 4.8W, power consumption is 58% and less than 0.12kWh

Anti Dust Feature
In metro cities like Mumbai, Delhi, Banglore dust accumulation is one of the biggest problems. The accumulation of dust has said to make quite lot of respirational problems. It’s essential that one keeps the houses clean and dust free, which becomes a task in the fast moving city life. Fan blades and the air purifier body are coated with Nano Technology paint which is hydrophobic and oleo phobic in nature. The advance cross linking density and lower surface energy of the paint fill used on the blade help reduce dust accumulation of the fan in the long run. Hence the dust does not stick to the blade as a thick dirt base as it is on ordinary fan. [61]

PARTS OF REMOTE
After deciding, ideating, designing and building up the Ananta till it’s main technicals, I moved ahead with the project for designing a remote for the same. A physical remote apart from the UI UX to control it wheneve the phone isn’t around for use. One of the big benefits of using a remote control for your fan is if you wish to use the air purifierion your ceiling fan then it avoids having to run an extra wire from your wall switch to the fan which you would otherwise need to turn it on and off independently of the fan itself. This extra wire is what enables the air purifier to be turned on and off from the wall. You can also control more than one fan at once by one remote and so could arrange – by setting the power switch on and matching them with the power switch in the remote – for banks of fans to be controlled by each remote, which is useful if you have a lot of ceiling fans to control. I went ahead with the same procedure of making a moodboard and then ideating it till modelling and user validation.

The purpose of this board is to help me formulate the mood that I would like to convey within my concept of the remote.

Pairing with Ananta
Remote is automatically paired with Ananta out of the box. All you need to do is to turn on the switch after assembling the fan and start. However, if your remote ever loses connection with Ananta and needs to be paired manually.
PAIR THE REMOTE MANUALLY Hold down the Power button on your remote for 20 seconds till all the 3 LEDs on the remote blink with red and green light 2 times. Point it towards the fan while pressing the button.
