Biomimicry is an interesting and broad area to be explored. The idea of biomimicry has been used multi-disciplinarily. My first precedent is the ICD/ITKE Research Pavilion. The project developers were inspired by the skeleton structure of the sea urchin. The main material is plywoods and they were joint together just like the way that the sea urchin’s shell plates notch into one another. This biomimicry design provided the project a durable and stable performance.

The second precedent is the Spanish Pavilion built for the 2005 EXPO in Aichi, Japan. The project is obviously a imitation of the structure of honeycombs. The hexagons on the exterior walls provided some of the characteristics of honeycombs, for instance, light-weight, solidity. But this project more likely mirrored the appearance of the honeycomb instead of using its properties.

These two research areas could provide me a flexible choice of development. The geologic environment of the

Merri Creek is very complex, therefore, I might need to develop a flexible structure with the capability to follow the

trend of the creek. I still got some inspiration from the Seville Metropol, the organic form of the structure may be

one of the solutions to my project. However, there are still few points need to be fixed. First of all, the migration

of the aquatic organisms. The first priority of my design will be minimum the impact to the current ecosystem.

The basic purpose of this design is to filter the water of Merri Creek. And the pattern of the Spanish Pavilion is reticular and very suitable for stopping pollutant in the water.

By changing the inner patterns, the size of the inner ‘hole’ seems to be varied. And the randomly distributed holes may help to catch the rubbish while not disrupt the water flow.


The rectangular grid is more likely to applied to the most common strainers. It’s simple but yet effective.

The variation of the size of the holes enables this web-system deal with pollutants in different shapes. And this web may help to classify rubbish based on sizes.

As the most important and representative architecture of the 2008 Beijing Olympic Games, the bird nest is more than just a stadium. The design of the Bird’s Nest need to meet several design objectives. For instance: large visitors capacity, fill the gaps between the frames (especially the roof), etc. There are semitransparent aerated film to control the sunlight and collect rainwater.

The warping structure of the stadium is remarkably expressive. But the whole stadium won’t be achieved if the interior supports are not well-designed. And the supports actually fused together with the outer frames and together created the interlaced huge bird’s nest.

04TECHNIQUE: DEVELOPMENT


The shape of the matters a lot. To design a water filter for a small creek a floating structure could help to stop the rubbishes on the water rather than trapping the aquatic creatures. Therefore, the original high-dense web structure might not suitable for such expectation.

This three iterations used some more regular structure (hexagonal, diagrid and grid) to form the web. The regular web structure can be fabricated easier and looked uniformly when deploying several of them.

Continuing developing the reticular structure, offsets were used in these three iterations. They were used in order to create holes between the nets which allow the water flows through.


These two iterations were tending to discover the possibilities of creating a multi-layer structure. The multi-layer structure will let the filter be able to filtrate pollutant in different sizes. To achieve this, the density of each layer is designed to be different.


By using culling, I generated several different patterns for the design. The culling tool was actually very helpful to my project which enables me to create some pattern with certain purpose.


After culling several patterns, the tornado shape draws my attention. Since when the water pass through a tornado structure and the water-flow will spin which may help to keep the pollutants inside the filter.

These iterations are intended to develop an alternative shape of the filter and discover the feasibility of the shape. The outcomes are very unexpected. These iterations are in a fair-shaped form. And these iterations may help to achieve new capabilities for my design.

05TECHNIQUE: PROTOTYPES


The first model is based on the triangular grids I generated at a relatively early stage. It is a fluctuant structure with multiple triangular frames. Unfortunately, the 3D printer was not able to print the exact structure of the iteration due to some parts of the digital model was too mixed up. It missed several edges of the triangles. But this failure has prevented me from making similar mistakes again. Also, this model gave me the first impression of my original design and helped me to improve it in the subsequent designs.


The second model was in order to testing the possibility of a waterwheel-like structure. This design was intend to let the structure keep spinning in the water to create a uncommon water filter. The current concern is that will this spin affect the life of fishes, and will this spin lose the litter which was caught by it.



The third model was 3D-printed as well. It was based on the hexagon grid structure created by Grasshopper. After reducing the number of the frame, and shrink the size of the superstructure. The model was successful printed, much better than the first model. The centre of this structure is hollow and with the gaps formed by the frame, water could actually flow through this mode just like a small sprinkler. I think this is one of the most important step of my project development. Within this model, it helps me discovered several design potentials but also some problems, especially fabrication. By using 3D printer, the definition of those printers is not enough for my design. Therefore, I’m now working on how actually could I fabricate this structure. Momentarily, I’m testing the possibility of building it by laser cutter and wires.



PART B

06TECHNIQUE: PROPOSAL


This diagram shows the early stage development of design ideas. 1. A single layer floating structure which can only catch bottles (or large litter). 2. A multi-layer structure which makes it possible to deal with litter of different sizes within a single unit.3. Several units spanning over the water surface to achieve a larger filtration area.4. Minimize the influence to the aquatic organics.

The blue areas show the possible deploying area of the units. My possible approach is to anchoring the structure onto the bank or create a bridge structure to actually support itself across the water. To me, I prefer using the anchor in order to achieve a disengaged deployment and uninstallation.

Flooding is one of the major problems this project might facing. As Merri Creek is the primary outlet of the stromwater in Melbourne.1 Therefore, the water level is highly related to the precipitation of the area. If my project is designed to be floating on a normal water level, they will be fully submerged during a flood. And moreover, they might be shifted or even be washed away.

Source: http://www.au123.com/home/u/cms/www/201306/01113913nq9w.jpg


The first approach is adjusting the water flow speed to achieve the balance of the unit in flood. The upper opening is larger than the nether one. And while the water flow is faster through the upper structure, the hydraulic pressure will press the unit downward. And with the anchors on the bank, the unit will be able to survive a flood.

The second way was add another anchor to the creek bed. This method is more reliable than the first approach, but it will increase the effects onto the aquatic creatures.

07LEARNING OBJECTIVES AND OUTCOMES


The core of the undergraduate design sequence is the development of both design thinking and dexterity with tools.2 ”“


The learning process of this subject is not very smooth at the start due to the lack of the essential techniques of Grasshopper. Indeed, it was hard to become familiar with a brand new tool, but the outcomes of Grasshopper fascinated me and they became the motivation for me to learning this great tool. By studying this tool, I started to realise the actual potential of this tool. Every time when I tried a new definition in Grasshopper, the outcomes are so different and unexpected.

Except the Grasshopper skills, this subject has taught me some new perspectives of thinking, especially to think critically and parametrically. Apart from focusing on the appearance, the performance of the design is also crucial. Also, as the foundation of architecture, the site, the users, the stakeholders and so much more is what we need to consider during the design process.

From Grasshopper, I can see the future of architecture. It has great potential and great prospect. Parametric design tools can help architects much more than what they are capable now. Therefore, I’m glad to learn these tools in such a practical subject, and I’m quite confident to the future of parametric design.
