Because the positions of joints and hinge techniques had changed along the prototyping process, but the joints were reused during the process, the joints I got were not ideal for the current connection.

This also influenced my choice for case study 2. The origami system was ideal for my area of interest where the integration of multiple patterning systems offers more potentials and variations to the system. And the relationship or the dialogue between those patterns are interchangeable with the movement of origami.

Precedent study PROJECT: BLOOMBERG PAVILION ARCHITECT: AKIHISA HIRATA DATE: 2011

The project was inspired by the growing nature of the tree branches. The design process was an integration of natural pattern studies and algorithmic scripting.

The resulted form was a combination of organically undulated surface and straight sharp triangular pieces. The structure parasited onto the existing building, and fused into it not just as a roof, but also as a wall, a door and a window.

The sculptural shape which according to Toyo Ito, represented â&#x20AC;&#x2DC;the intimate relationship between art & cityâ&#x20AC;&#x2122;.

However, we were more interested in the design logic and the techniques Hirata used in the project.The structure consisted of only isosceles triangles. They tessellated through simple logics which allowed them to expand constantly. Therefore, with the same logic, it is possible to incorporate any situation with any possible forms. It can be a facade, a curtain, a table and even clothes. It can be anything.

The site The site was at the entrance of the Ceres market. There was a walk way in front of Van Ray Centre (staff office), which connected the cafe, visitor centre and the market. There was quite a flow of people at the path. The facade of the office was also aging and dirty, we realized that there would be an opportunity to have a parasitic installation on the existing facade which would also have influence on the walking experience on the paths.

Site & Design

The project would adopt the material system of origami which was previously explored in part B. The installation we proposed would address following features and issues:

1. A parasitic installation which would become part of the existing building 2. Create connection between interior and exterior 3. Have influence on the walking path, creates interaction 4. Not just a wall, but also transit to other functions like canopy, providing shading.

We realized that the folding nature of origami would provide a dynamic and organic structure which could grow into different directions. As a parasitic installation, the structure would contrast the existing building in terms of both material finishing and the organic form. The folded origami would also revealed the aging facade in some parts along the flow of structure, which indicates the revealing of the nature under the manufactured structure. This would subtly demonstrate the key purpose of Ceres community, which was to unveil the destructed nature under human society, so as to promote sustainability.

Form finding

The design process of this project was a form finding process through algorithmic iterations and physical prototypes. Two of them were closely related to each other during the entire design.

Few sets of iterations were made for the form realization process, which

Axonometric view The structure sit across the entire existing facade, created a dynamic and continuous looking from the front elevation. It was tilted with an angle which allowed it to have some shading ability to the main paths and the windows. The transition from wall installation to a canopy demonstrated the growing nature of parasitic architecture.

However, the folding percentage was not enough to create an undulated form.

There was not much variation of folding along the structure which resulted in a relatively flat and simple form. But due to its simplicity, it had less problems in digital scripting compare to others and was easier to fabricate.

Axonometric view The most significant feature of this iteration was the transition from a wall cladding to a shading canopy, with a moderate rotation of form. Its presence was subtle and ambiguous. It had a really dynamic form and a sense of flow, which created great contrast to the existing building.

However, the twisted form was more complicated than how it looked like. The twisting resulted in the collisions of panels, and also some quad meshes at where it twisted. Nonetheless, the script was further developed at later stage with triangulation of quad meshes and also the sphere collide component to avoid collision. We would be able to solve these problems if more time were given and this could become one of our future developments.

Axonometric view The final form was a combination of last two best iterations. It was a balance between complexity and fabrication. It was a combination of two pieces of origami structures. One as facade and canopy, and the other one hovering on top of existing structures to create north side shading. There were spaces ‘inside’ the origami, accessible for users and created more interaction.

However, the final form was also just a selection from the existing iterations that we had at that design stage. It could be further developed with more appropriate evaluations and techniques (last iteration was an example). We stopped at this point because we thought this was relatively successful and already addressed the specificity of the site. Nonetheless, it was an ongoing process.

C2. Prototypes

6 prototypes were made in this stage before the presentation model. During the prototyping process, The real physical world was very different from what we saw on the screen, especially for things like materiality, fabrication defects and tolerance. Those things could only be realized during prototyping.

Meanwhile, the prototypes were not only for testing and representation.

Sometimes they were part of idea generation as well, like the form generation in prototype 1 and pattern visualization in prototype 4.

Prototype 1

The first prototype after part B was made of 0.6mm thick polypropylene sheet. At the time we were still unable to generate forms with varied foldings through grasshopper.

Therefore, this prototype was more of a form finding process which helped us to test and visualize the origami mechanism in reality.

The mountain lines were etched because it would be folded outwards while the valley lines were cut with dash lines.

166

167

folding cpacity It was much harder to fold than what we expected. The folding moment of each triangle occurred in different directions, and it became more difficult when we got into the centre of the sheet. However, the result was very successful in terms of its flexibility and structural integrity. It allowed us to understand the real potential of the system which also became a starting point of our digital script development in part C.

168

After the material testing in part B, we understand that the height of inflation was mainly depend on the size of the cut outs and also the material thickness. Due to the size limit of the origami panels, the metaball cut outs would be much smaller than part B prototypes. As a result, the 1mm plastic sheet (thinnest available in Fabrication workshop) was used. We chose plastic with glossy finish, due to its higher melting point.

This was the last prototype before the presentation model. After the material testing of aluminium and CNC router, we decided to laser cut mild steel at this stage. There were few reasons:

metaball installation

We thought about using bolts to attach metaball which would be similar to panel connections. However, We felt that the finishing quality of bolt connection was aesthetically not so good, and would affect the smooth finish of steel panels. Therefore, the metaball was installed by using cohesive tapes which were mainly used at construction site. Therefore, the installation was fast and clean and strong enough to hold the metaball.

making strips for fabrication 2 RULES OF MAKING STRIPS

To avoid panels with small angle of gaps

Because of tabs, if the gap between two panels were too small or with a small angle, the tabs would collide .

We believed that instead of making individual panels and connect them (like aluminium prototype), the final model should be folded from flat surfaces, which could demonstrate the folding nature of origami. However, while we were making polypropylene prototypes, we also realized that the folding was quite difficult especially when the material was hard. Therefore, we made a balance

between the two. We divided the final form into few strips to maintain the folding capability and also easier to fold.

The resistance of folding one full piece of origami is big. In this strip, the triangulation was divided into different strips. Therefore, the strips we made were all long and slim.

tabs and rivets

Rivets were used for the connection. due to its smaller sizes and easy fabrication. We planned to put 3 rivets at each tab for stability. But when we were making it, we realized that would take a lot of time and money. We reduced the number of rivets. At the edge panels, we used 2 rivets on the sides of the rivets, while only one rivet was used in other tabs. The effect was almost similar as initial plan.

huge wind load.

It worked for presentation model because it was only a portion of it.

However, there would be too much tolerance for making the entire model.

As a solution, small pieces of mdf with correct angles could be fabricated just to provide the correct angle of folding during fabrication.

â&#x20AC;&#x2DC;Foldfindingâ&#x20AC;&#x2122; as a methodology

This is probably the most significant among all future developments.

Our script was able to apply origami folding on any surfaces with any patterns. The fold would be determined differently through techniques such as attractor point, anchor point and unary forces. Due to the folding nature of origami, the form would be very flexible and could be digitally shaped into any form that the designer want. The scale could vary from facade installation to a table cover. Through iteration process, designer could find the most appropriate form for their design and to address their brief.

In terms of fabrication, we provided few appropriate materials in this project, such as aluminium. polypropylene, perspex and mild steel. They could work for a whole range of scales.
