Augmented Skin

ABSTRACT Augmented Skin project investigates the involvement between human body and architecture by initializing a dialogue among the fundamental elements of architecture and the human body. The fabrication process introduced, is based on the responsive behaviour between the solid the elastic and the mediator, inspired by the Bone the Skin and the Flesh of the human body. The project does not focus only on a material-wise analogy, instead the fabrication process explores new inhabitable properties through the contradicting aspects of its materialisation. The project aims for the proposal of inhabitable spaces inspired from the body in order to by embodied by it, as a recursive process, and seeks for the analogies based on the secrecy of human existence. A constant repetition of ‘infoldings’ and ‘outfoldings’, enclosure and reveal, formation and deformation takes place. The Augmented Skin refers to the materialization of these crucial limits and suggests inhabitable spaces where the inhabitant will be challenged to experience a phenomenological inhabitation of the flesh. What is presence becomes abstract, what is permanent is also temporary, thus a reality that fits into the perception of the human existence as an osmotic limit of matters like time and life.

AUGMENTED SKIN Concept

SOLID

ELASTIC

MEDIATOR

The Augmented Skin project concentrates on the establishment of a fabrication process. The conceptual language of the process is inspired by the human body. The skeleton the skin and the flesh are translated through the properties of the solid the elastic and the mediator. Their in-between interaction materialises the limits of the Grotesque skin and the formless form of the flesh. Spaces embodied with symbolism and phenomenological properties emerge. The initial research about the fabrication of the Augmented Skin was based on casting techniques inside flexible moulds. More specifically, a system based on the properties of three different material parts and the negotiation among them was introduced. The conceptual language refers to the solid the elastic and the mediator, which for the purposes of the fabrication translate into wood skeleton components, elastic fabric or latex membranes and cement casting processes. Based on the high level of dependency among the materials, as well as the unpredictable behaviour of them, a form finding research is initialized. The three initially separated parts negotiate under the forces of tension and deformation in such a way, that every time they deform and form unique substances where the limits of them cannot be distinguish but equally exist. Among the three parts of the system, Skin (Augmented Skin) stands out as the most characterizing limit. The limit between what is inside and what is outside, what hides underneath and what expellees outside as a form. The Augmented Skin relates to the Grotesque medieval Skin. The concept of the fabrication is based on the idea of a constrained skin as a porous limit, an osmotic area where all the three parts negotiate around the wider problematic about the dialectic of inside and outside.

All the possible combinations of the position of the rotating point give 9 types off components. For every component there is one individual position in which the skeleton can be locked and be structural, in all the rest positions the skeleton is able to rotate and be flexible according to the demands of the system.

AGGREGATION

RESEARCH

Aggrecant Simulation

The individual components act as granules. Having a variety in scale and size they are all made by the same system (solid-soft-casting). So all the components can be together deformed and formed into new shapes. The aggregation research for the system begins for the method of packing. Elastic membranes and soap films, circle packing and random packing aggregation are the initial references. The skeleton can be aggregated in a random emission-distribution (free aggregation), while the flexible membrane could be related with the packing aggregation of the common experiment of soap bubbles packing having a local constrain of the neighbour membranes and a global, that of the bounding box.

The second approach of aggregation research is to use dynamic simulations such as fluid and vortex simulation. The concept behind that is the fact that our component is based on a very simply logic and it could be aggregated in a infinite way. Further more the components are vulnerable to external parameters and forces witch the are able to reflect in a local as well as global level (small scale-big scale). Thus in order to express the properties of our system a packing geometrical aggregation is very limited. The vulnerable and dynamic nature of the system can be better expressed through dynamic simulation taking into consideration parameters and environmental facts.

AGGREGATION

RESEARCH

Packing Method

During term 1 the aggregation research was based on the individual components according to the variation of their skeleton analogiesdimension, different sizes (scale) and finally different amount of material deposition inside them. For the design research we investigate all their possible combinations and scale variations from a small aggregated object to a bigger architectural scale.

Aggregation of individual components

FABRICATION OF COMPONENT Physical Experiment

The first step after the wood skeletons are wrapped around the fabric membrane is coating. The material used is latex paint. A thick layer a material is applied and then the components are left to dry. The time required for that is approximately 1-2 days

After the coating dries the membrane is waterproof but still flexible. Then we start casting them. For the casting we use a mix a plaster and black pigment. We inject the mixture through a small hole and the close it through stitching.

While the casting material is still liquid and the components soft we compress the them into a box. The outer boundaries of the box, the pressure force as well as the gravity force act as external parameter that deform the components and form them into a unique combination.

Finally the skin is piled off to study more carefully the result. Each component is deformed into a unique form, reflecting the negotiation with the neighbour components the constrain of the skin and all the rest constraining forces. The output are unique deformed tiles.

For the prototype after assembling, the only force acting to the system and deforms it is gravity. The deformation is translated into unique connection between the components .This connection quarantees stuctural support. So the relationship could be descriped as: deformation

structural support

Since the prototype deformation is related to gravity it could be notices that along the height of the prototype: height

CONCEPT OF SKELETON Strand Range Of Movement

In order to use the properties of the skeleton in a more efficient way a new distribution logic is introduced, the system of the strand. The skeleton components are placed along a strand and then wrapped all together inside elastic fabric moulds. With this way the skeleton components will be able create structural forms, without falling apart, while in the same time the system keeps all its properties regarding the deformation and interlocking ability. The new individual components follow some main variables for their design. These variables such as the length and the number of the cross points express different functional demands along the strand. The length of the sticks is related to the deformation of the membrane as well as with the ability of the component to expand towards the space. The cross points offer stronger connection points and also the may allow to the strand to rotate. The next diagram is displaying the catalogue of the variation of the individual components according to their main variables. Questions like

â&#x20AC;&#x2DC;

If the skin is constrained by the skeleton , and the skeleton covered under the skin where does the skeleton ends and where does the membrane beginâ&#x20AC;&#x2122;

emerge. The project tries to answer this by

introducing a design login where the skin and the skeleton are in a continuous dialogue deforming and forming together new abstract forms something in-between of skin and bone, a constrained flesh.

CLUSTER

CLUSTER DENSITY VARIATION

The distribution of the bone components of the strands is following their functional purposes. When the density of them increases they form the cluster. According to the variation of their density they form big and small clusters.The cluster is one of the most strong parts of the skeleton able to bring together different bones and strands. Therefore the cluster as a design language can express better the conceptual idea of the system about negotiation and interlocking behaviours.

CLUSTER CASTING VARIATION

Furthermore the cluster apart from a hight density moment of the bone components it is also characterised by the exessive presence of the flesh. According to the different amount of casting material, different deformations can be achieved. The matter of the flesh is is emphasizing the character of the mediator. It is mainly the flesh that will allow the negotiation with the neighbour bodys as well as with the existing landscape conditions.

FABRICATING THE FLESH Pouring As A Making Process

fig. 18

fig. 19

Furthermore, the pouring of cement in the fabrication process of the Augmented Skin is the crucial factor that causes the emerge of the final form. The initially separated components deform and form unique interlocking relationships among them. However casting is what at the same time causes the dynamic of the negotiating behaviour of the system to stabilize. The three partsâ&#x20AC;&#x2122; system is alive while all the parts of it interact, however the time of their interaction is equal to the time of the casting. After the cement has been solidified the system is no longer interacting is has been frozen. The time of its interaction relates to the time of the human life. The project suggests the proposal of a monumental time, the memory of what used to be alive. The negotiating character of the system is emphasized by underlying the temporal moment of its creation into a monumental moment of its death. Therefore it could be said that for the project Pouring as a making process relates with the framework of material constrains, causes deformations and interlocking relationships as well as implies symbolic time. The poured concrete is kneaded with the membrane and the constrain skeleton under

It attempts to emphasize the constrains of the skin and a system where the presence of the flesh will occur as consequence of its high dependence from the skin and the skeleton. Therefore different configurations of the system result to different deformed bodies.

Growing simulation are utilized to distribute stick comonents along the strand, and to fulfill the idea of aggregtaion of skeletons, which are wooden sticks, and to achieve unprecedented design. Via this simulation, the sticks can be dispersed and nested to observe how they react together, keeping their unique position and maintaining structural stability.

GENERATION OF THE SKELETON Top View Density Analysis

The system implements different behaving particles in a particle spring connection system for the formation of a structural skeleton for an installation. When certain distance parameters are met, they create new particles and bind with a spring. This property of the system, creating new particles and connection is our reference to the Dla system an algorithm referring to the growth. So the generation of the skeleton is growing under certain parameters and with variation in the size and the length of it. The future step is about the extra (triangular) connections between the particles which will allow to the system to be self supported in the space. Finally static ground plate particles are necessary to be introduced into the system in order to define the installationâ&#x20AC;&#x2122; s starting and ending point.Application of the properties of the Spring connectionDla system to the skeleton of the structure.

The distribution strategy is developed, aiming to link the emerge of the skeleton with a terrain scenario.The parameters that can control the distribution such as directionality and density are used to translate the pattern according to spatial units and paths that connect them. The main parameters that relate the skeleton with the existing conditions of a site are high density distribution on the extreme landscape conditions, void spaces along preserved existing conditions , directionality along the line and view points as the target of the destination.

The final simulation for the generation of the skeleton is a combination of the DLA algorithmic distribution and the flexible spring connection system with a particle based logic. So the particles are generated and grow according to DLA rules. However they are connected with spring connections among them. Therefore according to repulers and attractor as well as external forces, it is able to contol the direction, the density, the speed, t h e d e n s i t y, t h e n u m b e r o f t h e i r p o p u l a t i o n a n d t h e restLenght

of their connection. Furthermore some particles may be locked according to physics and cause the creation of clusters. The purpose of this case study of how to control the parameteres of the alorithmic system that we initialize is to link the properties with the depands of a terrain scenario and the generation of the flexible skeleton of our system along it.

The distribution of the strands is achieved through a growing pattern simulation and factors such as repulers and attractors. In that way the continuous growing pattern is taking into consideration the surroundings and adjusts to them.

Since tension is one of the main parameters of the skin, a case study to analyse it is developed based on the properties of a spring system. In this case study each surface is translated into spring line configurations which are able to deform according to attractors and repulers resulting to deformed surfaces able to perform structurally.

SITTING OBJECT Digital Exploration

The digital experiment of the sitting object refers mainly to the properties of Strand component. Seperated strands inflated with different materials like cement and e x p a n d i n g f o a m , r i g b e n d a n d t w i s t a m o n g t h e m i n o r d e r t o f o r m t h e c h a i r. T h e selection of material is according to the functional purpose they represent, cement for a solid and structural base, rigid expanding foam for the ligher parts of the chair like the arms and finally soft expanding foam for the sitting and back part.

118

119

SITTING OBJECT Digital Exploration

Following the initial research of the design language the stick components of the skeleton are distributed is such a way so as to quarante flexibility and junction - rotation points for the strands. So in the base of the legs and the corner points of the sitting part and the arms of the chair there is higher density of small cross components, while the larger pieces, the bones of the stucture form the legs the arms etc. The skin is constrained from the point pressure of the skeleton and the final form is achieved when the stucture is casted. Then after deforming the seperated strands interlock and they form one unique, solid and structural sitting piece. 120

121

SITTING OBJECT - FABRICATION Making Process Of The Prototype

fig.

fig. 40

The making process of the chair consists out of seven basic steps. First of all the wood skeletons of the sticks components are made. Then the flexible fabric moulds are filled with the wood components. After that the elastic stands are placed inside the outer wood framework according to the design of the chair. After fixing their position into the frame a thick coating layer of PVA glue is applied. When the coating gets dry (approximately one day) the casting process begins. 122

fig. 40 Prototype: Top View, Frame importance

fig. 41 Prototype: Basic steps fig. 42 Prototype: Scale 1:20 fig. 42

After the material research and the experiments with the amount of material deposition we start making the chair by using a big wood frame box to become the bounding box of it, making sure for the legs to be straight. Then the flexible strands are placed inside the frame and they get coated with a thick layer of PVA glue.

The wood frame is the main constrain for the elastic moulds which their flexible properties they are able to bend, twist, rig and deform around it. As the last last step cement is used to cast inside them and express into a solid object their interaction. After the cement gets dry the outer wood frame is removed. 123

124

The prototype of the sitting object was based on the idea of kneading individual strand components into the unique substance of a chair. When the strand components knead among them they become unique matches for each other. According to their relationship the final form is achieved.

125

PROTOTYPE FABRICATION Strands Rotation

One of the main tools used for the making process of the chair is the strand concept. Even though the skeleton of the structure is solid, the flexible membrane as well as the combination of the stick components along the strand allow them to rotate, bend and twist. The spatial distribution of the stick components follows functional purposes of junction and bridge points.

126

After the membrane - skeleton strands get dry, the membrane becomes waterproof but still flexible. Then is time for the final stage of the process, the casting. The casting material used is a mix of concrete and plaster which is gradually added inside the membrane moulds The amount of the material is one of the crucial factors that determine the deformation of the membrane.

127

PROTOTYPE FABRICATION Strands Interlocking

The amount of material deposition is connected with the deformation of the initial elastic mould. The deformation refers to the weight and the structural optimization of the crucial points such as the base of the chair , which is important to be strong and solid, or lightweight areas with an ornament character to the design of the chair like the arms of it. Apart from that, highly deformed areas represent strong connections between the different strand components. Taking the further into consideration we come to the conclusion that the deformation of the moulds will transform the initially homogeneous elastic strands into a new solid object with different areas stress points according to the demands of the structure, in this case, the chair. fig. 43 Sitting object fig. 43

1:1 scale

Taking that further into consideration we come to the conclusion that the deformation of the moulds will transform the initially homogeneous elastic strands into a new solid object with different areas stress points according to the demands of the structure, in this case, the chair. The initially separated parts of the different strands are connected by the third ingredient of the system, the casting process.

128

After casting and deformation of the soft membranes they interlock perfectly to each other. The combination of the components A+B+C is giving us the combination of ABC which is a unique perfect mach for each one.Thus the poured concrete is kneaded with the membrane and the constrain skeleton under the forces of gravity. Furthermore the components are kneaded in a double sense, first as individuals following their making process, but also between them, and eventually as a whole.

GATE I

The making process of GATE I is based on the connection of strand components on the floor,

and then they are pulled up to create an arch shape. The strand components connect after getting covered by

fabric. After the shape is

created, it can be coated and casted.

GATE II

The prototype of GATE II (part of a bigger unit)

aims for a bigger scale without the use of any

outer framework. The skeleton becomes also the scaffold for the structure as well as the reinforcement for the cement.

The scaffold, the outer wood frame that was used in the prototype of the sitting object was a limitation for bigger scales. So in the next prototype, part of a bigger unit, we aimed for a bigger scale without the use of any outer framework. The skeleton becomes also the scaffold for the structure that remains inside and also becomes the reinforcement for the cement. Finally the skin components are introduced between the strands with a gradual transition from the strand to the skin with variation in their pattern according to their configuration along the gate.

PROTOTYPE GATE II Pattern Variation

The combination of the surface components and the flexible strands is based on the tensile deformation of the system. The pattern as well as the design of the skin conponents is a result of different tension forces according to the position and functional purposes of the components to the system.

Latex has the probability of laser cutting, sewing and time saving because of the lack of covering glue on membrane. In addition, it can be simply glued and works within a few minutes. Even if it is stretched a lot, it sticks together.

To explore the use of tension, the relationship between the skeleton and the membrane was invertigated. It is shown that due to the different size of the latex with the related sizes of sticks, the extent of the degree is different becuase as the distance between the stick component and the latex pipe moves closer, it makes them tight and therefore unmovable. This demonstrate a clear difference using tension according to the ratio of diameter of sticks and latex. Latex has various thickness from 0.2 ~ 3mm. While thinner, it is more stretchable, but the tension is low. In the case of using extreme tension, it focuses more one overall structural stability and on reducing material use. L A T E X

UTILIZATION OF HIGH TENSION

Divided structure system

For more flexible installation, structure is divicied into two part, foundation and ready strands so that it is possible to assemble and disassemble. So, due to the seperated parts, both foundation and strands can be replaced easily in case of chaging length or design. With cast foundation, structure stands relying on the tension of latex.

The length of latex was defined as 2/3 of the total length of the sticks. Only the bottom part is casted for foundation of structure so that it is stable enough to stand. 149

MATERIAL PROPERTIES Thickness Variation

fig. 51

According to the thinckness of latex, when materials are poured into the same sizes of latex components, thinner latex deforms further compared to the others owing to the fact that the thicker the latex is , the higher tension will be. As the latex is thicker, it is more difficult to stretch than when using a thinnner sample.

For the bottom section, foundation segments of strands of strands and skins are cast for further stability and are nested to make foundation area completely robust and immovable. Thus, the whole stcuture is stabilized from bottom to top.

CONCEPT

The Concept of the design proposal refers to the application of the fabrication as an extreme building process initializing a dialogue among the fundamental elements of architecture and the human body. By extracting human anatomy moments from our design, the wall is tho ug ht as an e xte nsion of t he skin, T he supporting elements relate to the bones and the skeleton, and finally the binding process of casting is rather thought as the mediator for the expose of their relationship

166

SITE Introduction To The Site

The design proposal refers to the design of a lanscape museum about the history and the dissaster of st francis Dan in San Francisco in 1946. The dam was a magastracture opposingto the natural elements of the landscape. The augmented skin building process is then usedin order to rather suggest an alternative meagastructure making process which rather refers to the fragmented nature of the destroyed dam and the holistic truth of a deep skin, a skin where the contrains, the reinforcement, the cement and the supporting skeleton are emphased individually and in the same time they are blended together unable to seperate they coexist and cause the emerge of the museum which as a stucture as well as its process of making is in relationship with the surrounding landscape and and remains of the the ruin. Along the ruins of Saint Francis dam in San Francisco canyon a landscape museum about the dam and its collapse is purposed. The design logic of the flesh, the strand and the skin translate into different spatial conditions of the museum while the inhabitant of the building is in a continuous transition from enclosed, to semi open and open spaces.

Possible Rotation Angles Of The Sitting Object

The final sitting object is based on the surface components design logic. A more complex system of the tensile stucture is introduced. The configuration of the main strands, supporting elements of the system, defines the expansion and the size of the skin elements between them.

The design of the final component is the equalibrium moment of the tensile forces among the elements of the system. After the component is generated, the aggregation of it defines the sitting object which is able to rotate along the axis x,y and z.

CONCLUSIONS Taking into consideration the perception and role of skin in different times, it could be said that the skin of the project aims for an extremely constrained and thin skin that relates with the properties of Medieval skin. This skin also acts as a unifier based on the perception of becoming the place where different processes meet together and negotiate. It is porous and grotesque, since the inside process of its matter is expressed on its surface to such an extent that the skin cannot be separated from its inside. It could rather been thought as the crucial limit of its flesh. The project does not focus on a material-wise analogy of its three part’s system with the skin the flesh and the bone of it. Instead the fabrication process explores new inhabitable properties through the contradicting aspects of its materialisation. The phenomenological inhabitation of the deformed bodies of the Augmented Skin prototypes, relies at their constant interaction, the extreme limits, the deformation, the osmotic surface of the skin, the constrained flesh, the interlocking behaviour, the perception about time between their interaction, what expels out and what remains hidden. The design proposal materialises in different inhabitable conditions the idea of the negotiation that takes part on the limit. On the crucial limit of the skin a dramatic polarity between the dialectic of inside and outside is achieved. That is result of constant repetition of ‘infoldings’ and ‘outfoldings’, enclosure and reveal, formation and deformation The Augmented Skin refers to the materialization of these crucial limits therefore the inhabitant of the building is challenged for a phenomenological inhabitation of the flesh.
