B.1 Research Field

Strip/folding is a mean of generating both aesthetic forms and structures. Through computational design, designers find ways to break away from the conventional dilemma of materials and structures. Strip/folding is one of the approaches to cross the boundaries. Forms can be decomposed into basic strip components while folding can add to the profiles. The forms can be manipulated through parameters and performance can be simulated. It simplified fabrication and construction process and maximize the potential of materials.

ICD/ITKE Research Pavilion 2010

The innovative structure demonstrates the latest developments in material-oriented computational design, simulation, and production processes in architecture. The result is a bending-active structure made entirely of extremely thin, elastically- bent plywood strips. Traditionally in the virtual processes of computational design form and force are usually treated as separate entities, as they are divided into processes of geometric form generation and subsequent simulation based on specific material properties. The research pavilion uses an alternative approach: here, the computational generation of form is driven and informed by material characteristics and behaviours. The structure is entirely based on the elastic bending behavior of plywood strips. The strips are robotically manufactured as planar elements, and subsequently connected so that elastically bent and tensioned regions alternate along their length. The force that is locally stored in each bent region of the strip, and maintained by the corresponding tensioned region of the neighboring strip, greatly increases the structural capacity of the system. In order to prevent bending moments, 80 different strip patterns constructed from more than 500 geometrically unique parts were produced. The computational design model is based on embedding the relevant material behavioral features in parametric principles. These parametric dependencies were defined through physical experiments focusing on the measurement of deflections of elastically bent thin plywood strips. http://icd.uni-stuttgart.de/?p=

B.2 Case Study 1

Biothing - Seroussi Pavilion

With ‘biothing’ the New York based architect Alisa Andrasek founded a trans-disciplinary lobratory that focuses on the generative potential of computational systems for design. The project explored in-between algorithmic states by trans- coding 3 different algorithms. Electro-Magnetic Field developed through Biothing’s custom written plug-in for Rhino was initially distributed in order to develop structural trajectories for the roof condition. Resonating pattern was imprinted into the ground creating emitters for the second algorithmic logic _ radial wave interference pattern that formed global geography of the field. Finally, class 4 Cellular Automata was used to re-process wave data by imprinting micro-articulation of the ground.

By adding spin force and merging the field, the field l i n e s l o o k s m u c h m o r e interesting than the original project. This one is the best of the best four. The curvature of the field lines are elegant than natural. There are more possibilities to apply to real design. This one is similar to the third one but with different curves.

B.3 Case Study 2

DOUBLE AGENT WHITE

Double Agent White functions to achieve a maximum degree of morphological freedom, structural continuity, visual interplay, and logistical efficiency within a minimum degree of components, and performative hierarchies. It is composed from the amalgamated intersection of 9 spheres of unique radii forming one continuous surface. The sphere primitive defines continuous double curvature across the piece for material rigidity while simultaneously allowing for larger decomposable units able to be optimally nested for efficient storage. The surface condition is composed of two parallel yet divergent sets of distributed agents. The first, a controlled macro set is describing the overall geometry into the minimum number of developable elements able to be cut within the constraints of flat sheets of aluminum. The second, higher resolution, more schizophrenic and expressive set is detailing aperture as ornament. The former informing the latter. Bound within the logic of assembly mobility, and spatial nuance, Double Agent White coheres myriad formal and technical constraints into an immersive environmental whole. https://theverymany.com/12-atelier-calder/

+species 2

This iteration of Traveling Salesman looks good to me.

But the structure and buildability are problems.

This one is good in terms of the size and number of the

holes. It is also easy to fabricate, either using 3D printing

or H clip connection.

This one is the best of the three in terms of the

connection to design brief. However the material choices

and buildability are limited.

B.6. Technique: Proposal

My target client is the Early Learning Centre, which is a specialised research and demonstration kindergarten at the University of Melbourne. It is located besides Merri Creek. What I propose is a program for children to acquire the knowledge, skills, attitudes and values necessary to shape a sustainable future when they grow up. And I am thinking about designing a uniform for the kids in the kindergarten, that provokes their interest in natural environment, and encourages them to discover the natural environment around the kindergarten. The garment should firstly have some connections to the natural environment around the kindergarten. It also has to be interesting in the kids' perspective. As it is for children, it also has to be smooth and lightweight rather than sharp or chunky. One of the most important qualities of my prototype is that it has a curved and continuing surface, with holes of various sizes on it. One possibility is to allow children to create interesting effect using natural light. Another possibility is to have kids play with water. The prototype is thin and lightweight and should be suitable for kids. One drawback of the design is that it is not flexible enough to keep up with movement of body. This goes against the purpose to have kids exploring the environment. Possible solutions include changing the material, splitting the components and connecting them with flexible joints, or keeping the design in a proper size that avoid obstacle.
