B.1. Research Field---Strip and Folding
Strips and folds can be seen in structural elements and pattern in the architecture. It looks like the combination of origami and weaving. Actually, strip and folding is the combination of dynamic and smooth. The dynamic folding on the smooth strip create a innovative expression. I’m interested in this field because I think there is more potential and design possibility of merging the smooth and dynamic together to create innovative and complex form by parameter in the grasshopper. It is also interesting that, Strip and folds structure can achieve the outcome within surface also could generate the pattern on the surface by itself. I was inspiration a lot not only about the strip and folding but also the way of dealing with the pattern.
B.2. Case Study 1---Seroussi Pavilion
Biothing developed this project and organized by art collector Nathalie Seroussi, which located in the ground of villa in Meudon, near Paris. Seroussi Pavilion was inspired by the two on-site brickwork and concrete sculpture by Maison Andre Bloc. The idea of maze was adopted in the concept, which integrate the structure to organize the spatial pattern and fabric of the pavilion. The design process like woven into the fibres. The change of the self-modifying vector-based pattern from the simulation of electromagnetic field. The attraction and repulsion of electric charge. And the form was changed a little through the frequencies of the function type. I’m interested in this project because the lots complex indeterminacy in the pavilion. The unpredictable attraction and repulsion of electric charge in the electromagnetic field to get surprising outcomes. And the pattern can be self-modified with the process, which add the indeterminacy of achieving outcome. The unpredictable outcome is very surprise for me.

B.2. Selected Outcome Selected Criteria I’m planning to design a curve shape acoustic pod made of dense strips in the office. To be considered that acoustic pad provide quite space in the office and was used to separate the space of offices into many different unit. I think curve have more possibility of different ways of dividing the space smoothly. Additionally, adding pattern on the strip or make the strip become more dense to keep acoustic effect. Therefore my selection criteria is the structure with smooth curve and the strip with pattern or more dense than others.
Design Potential
During the process of changing the parameters, there is a form-finding process. I try to find the potencial of the performence of shape and density of the strips, which inspire me the way of curving the strips.
The form was generated by the flowline plugin in grasshopper. The irregular cell with different density strips, which inspire me the way of weaving the strips of pod.
I changed the basic parameter, line charge to get the form. The radioactive lines from the center to form different shape and density of strips.
I used the spin force combine with the point charge and line charge to change the form. The attraction and repulsion of electric make the cluster form or the radioactive form.
Line charge was used to achieve the form. The strip was generated as pattern by itself is very interesting.

The lines generate from the ground appear as radioactive lines, that similar as the strips structure in the Seroussi Pavilion. However, under the force generated by kangaroo tool, maximum spatial performance could be achieved.

B.4. Technique Development
B.4. Technique Development Volume Simulation Volume Simulation could be used to predict the different volume performance at different motion and different time. During the process, I can see the maximum and minimum performance of the form. Getting the unpredicted outcome in this form finding process.
Surface Simulation VIn the Surface simulation, I can see the form performance of how flat of the surface could be and how maximum spatial performance of surface could achieve. During the simulation, I can challenge more abstract form contrast to original one.
Anchor Points Kangraoo Tool Baked squaregrid and set multiple anchor points in the kangraoo to generate different surface form through: ---Setting points in different area of squaregrid ---The number of anchor points ---Different base grid( Radial grid or Hexagonal grids)

Generating force in vertical plane Could make the volume very flat or very spatial.
Amplitude + UForce Generating force in horizontl plane Could make the volume become more abstract like twisting.

Adding pattern on the surface
B.4. Selected Outcome Selected Criteria I was planning to design a curve shape acoustic pod made of dense strips in the office. After the reverse engineering, I have little bit change of my idea. I want to create more dynamic curve rather than regular curve. I’m planning to design a wave surface to be the acoustic pod. Because wave is dynamic and keep changing. When the people sit inside the pod, they will be surrounded by changing patterns and wave surface, which provide a indeterminacy and unpredictable felling.
The form was got during the process
of volume simulation. This form was interesting and give a way of dividing the space through the radial lines generate from the volume. And the edge of curve is very sharp, which is interesting as well.
The wave of the surface is vey organic, which inspire me the way of generating the weave surface. of the acoustic pod.
The form was generated by UForce. This twisting form is interesting , which inspire me a new way of wave surface generating.
This wave form is very close to my original idea that the strips generated from the points of ground and achieve the spatial performence by kangraoo.
B.5. Technique: Prototypes
For the fabrication, We use 3d printing to fabricate, because we thought laser cut usually used in something hard or straight, 3d printing is more easier to deal with the curve. However, after pring the model, i found that 3d printing has restriction in model making. The pattern we to show in model is gradient, keep changing in different area of the strips. But it is not obvious in the model. So we going to use laser cut to do the model. In addition, we want not only visual wave model but also physical wave model. So we going to change the material and joints.
Materialization The material we used in Prototypes is plastic. But we found that plastic is too hard. We are going to change to Timber veneer Spotted gum with paper back. Because timber veneer is soft enough to make the curve strips and the paper back increase the strength to avoild be broken.
Connection Each strips connect with pin joints to keep flexible wave. Or we are going to choose 3d printing pin joints to fit the different angle and direction in the complex form.
B.6. Technique: Proposal
The design proposal was a wave shape acoustic pod made of dense strips with gradual change pattern in the office. Wave is dynamic and keep changing. When the people sit inside the pod, they will be surrounded by changing patterns and wave surface. The dynamic wave and changing patterns provide a indeterminacy and unpredictable felling. Additionally, the design was to create a spatial vortex, which make people would feel drawn in to and sit down. It is like a secret and interesting space in the office. The wave pod was weaved of strips with different density in the different area. And the gradual change pattern on the strips. Both will create different acoustic effects. The area where has dense strip and closed pattern avoild the sound, provide the private space. However, people sit near the striips where are loose and have hollow pattern can contact with outside. It is like open space. Therefore, the wave acoustic pods is semi-private space.
B.6. Technique: Proposal Form Finding Process Our design inspiration from the wave surface and the radioactive strips generated from the points of ground like Seroussi Pavilion. We try to make the strips reach the edge the hollow pattern of the surface. During the process, strips intersect each other to form the pattern by itself. Additionally, we add pattern in the surface, to create more complex form. We make the pattern with gradual change, which make the design become more interesting.

B.7. Learning Objectives and Outcomes Through the Part B study. I become familiar with grasshopper a little bit. I found that, the computational design give lots of design potencial. Lots of unpredicted outcome could appear through the process of changing parameters. Research Field make me fimiliar the parametric process of generating precedent through grasshopper. That gave a sovleproblem thinking. When I first doing Reverse Engineering, I think it is difficult for me to figure out. After studying the tutorials online, which improve my logic thinking of process parameters generation process. Prototypes is a new model making process for me. I was taught the method of Materialization and joints connection. It is like the testing process before making model. It is a very important because it impact the way chaning design to reality. My prototype did not satisfied me due to the material selection. But the process is significant to get opportunity to deal with the design ides to reality.
