RESERACH FIELD

B1.1 STRIPS & FOLDING Strips as a architectural compoent is commonly use in comtemporary design since architecture is the combination of art and structure. 1 Strips can not only serve as a structure element but also form the skin at the same time. It fullfills the two basic characteristic of architetcture. Moreover, parametric design as a new trend in architecture also help to push the boundary ofthe use of strips and floding. It is hard to fabricate complex computation-base geometry by using traditional construction method.2 However, complex geometry can always be decompose into simple basic geometries. Take UNDER STRESS done by THE VERY MANY

as an example, the skin of this structure is double curve surface. They decompose the skin into flat strips which are much more easy to fabricate.3 Therefore, strips and folding enable the work flow from computation to fabrication. Strips and folding also is a good method to incorporate with material properties. In the project EPFL and ICD/ITKE Research Pavillion 2010, they both used strips and folding to highlight the bending properties of their material. 4&5

CASE STUDY 2.0

B3.1 REVERSE ENGINEERING PROJECT: DOUBLE AGENT WHITE ARCHITECT: MARC FORNES & THEVERYMANYâ&#x201E;¢ DATE: 2012

Double agent white is one continous surface formed by 9 intersectant spheres. this project is one of the prototypical architecture. The key idea of Double agent white is to generate fabricatable developable surfaces to construct double curved surfaces. Double agent white ids defined by a double agent system. The first one is to control the overall geometry with

minimul amount of developable surfaces that can be cutted in a flat sheet. The second agent is higher resolution, more schizophrenic and expressive set is detailing aperture as ornament. The resulting structure adheres to a myriad of formal and technical constraints that provide a dynamic structure of spatial nuance.6

en combine with light. We want to use dichroic film as our material since ne on the right is PETG plastic which is clear perspex- like material when ETG plastic can be color coating. However, ee did not get our intended polypropylene and perspex since they have similiar materiality.

PROTOTYPE 1 Prototype 1 is based on the strips interation from B4. I choose this interation as the starting point of prototype is because our design brief is to capture the dynamic motion in the ball room. This floating strips give me the sense of movement. However, it is hard to make the strips floating in the

air without any support. So I made a transparent frame to hold it up. This prototype is aim to test the effect of irregular floating structure and its framework.

PROTOTYPE 2 Prototype 2 is also to test how irregular curvy structure can be join. Moreover, we want to see how flexible plastic-like materialperforms in different kind of joints.

of what we expected due to the strength and and flexibility of polypropylene. We should consider more about the material perfrmance in the next design.

We used wires and pin joints to join the strips together. Then the strips perform in a different way

PROTOTYPE 3 These 2 prototypes aim to push the boundary of joints. In this interation, each geometry consts of 13 pyramid shape sub-geometries. These 13 geometries are shared edges on the top part. We chose these pyramid have a volume inside that can incorporate with lighting effect.

In prototyep 3, we tried not to deal with the top part. Instead, we used a 3D print joint to hold those sub-geometries. As a result, the geometries are fixed.

PROTOTYPE 4 Since we already tried fix joint. A flexible connection is introduce in prototype 4.

the design possibility will be enriched in this structure.

The 13 sub-structure are connected by metal rings at the top part. Flexible movement are possible in this prototype. Due to the flexible movement,

PROTOTYPE 5 Prototype 5 is to fabricate double curve surface through decompose the surface into triangulated panels. Since our material is farely rigid, we want to make the structure more flexible thriugh its joints. So we used the same joints as pro-

totype 4 to allow the movement in the share edges, However, these leads to a new problem that we can get the same angle as our rhino model. In the next step, 3D print joints can be one option for this kind of model issue.

PROTOTYPE 6 Due to the problem we came across in prototype 5. We decided to try 3D print joints and more rigid joints in a similiar triangulaed panels structure. The 3D print plate did help us to get the exact angle of our rhino model but the cable ties failed this task due to its dimensions.

When we tried to tie the structure into the perspex by using wires. It immediately changed its shape. In the next step, we will think more about framework and how to better hold the structure that we create.

PROTOTYPE 7 Prototype 7 is to try conceal joints in flexible material. At first, we attempted to glue the shared surface of this structure. We failed because glue does not perform welll in polypropylene and the glue mark was not aesthetically acceptable.

Then we just staple the shared

PROTOTYPE 8 The last prototype is to refabricate a similar curvy surface as our previous case study. By applying tensil strength into the structure base on the materiality of polypropylene, the curvy surface actully form a volume . A rigid joint is needed for creating strength. So we used metal brads to shared vertices of these

triangular panels. For next step, we will record the material performance data for the part c parametric design to get a more contrallable outcome.

TECHNIQUE: PROPOSAL Double curve surface and irregular geometery may be easy to generate through parameteric design. However, it is hard to covert them to actual fabrication stage. As a result, we produced a few prototypes to test the limits of material and joints at this stage, aims to explore the potential of our actual fabrication and try to find out the most effective way to convert our design into reality. For the next stage, we will more focus on: Bring more depth & volume into our design. For part B, we were mainly deal with surface. But a gemetry that have a volume will be more suitable to incorporate with lighting and acoustic need of a ballroom.

tested out our idea using some materials that have similar properties. But real material may perform in a different way. Their weight, span possibility will heavily influence our design such as the connection in our design. Capture a motion in a ballroom. Our design brief is to create a refelction of the dynamic motion in the ballroom. For now, our inspiration is just from our case study, a real ballroom motion may be help to push our design brief further. Pick a the most suitable potentialway. In part B, we opened up our possibilities by protyping. Now it is time to narroe down our stream. And try to find the best way to balance the difficulty and reality.

ation of detailing, joinary and material performance. We have to choose the suitable material and connection type for fabrication.

The whole part B flow is very clear and logic. We first research the parametric design method. After B2, we got more knowledge in grasshopper and how parametric design works.

From the beginning of part B, I was exposed to a series of precedent through research, interations and reverse engineering. I can see how the architects turn monitor image to reality. And this also the filed we need to spend most of our time on in part C.

B3 enable me to create my own defination by reverse engineering an existing project. Before, I was just random component to whether they works or not. From B3, I get to understand the logic of parametric design. The other important part I learnt from part B is how to convert computation design to fabrication. In grasshopper, a few click may already can generate a amazing structure. But when it comes to the fabrication stage, the structure will fail for any misconsider-
