IDEATION NATURAL

PROCESS Sunflower Disk

Sunflower represents its beauty that really captures my attention once I saw it. According to King (2004), it characterises the brightness during summer and its gigantic yellow flower heads always follow the sun light which portrays the idea of happiness in the summer. Furthermore, its disk depicts the spiral pattern in nature that is related to Fibonacci Sequence (Segerman 2013). Its pattern also shows the brightness proportion which relevant to the Poling reading. In order to find the analytical drawings, I drew dots on the pattern and followed the movement. At first, I only found one direction of spiralling that I develop further becoming the balance analytical drawing. Then, I found another direction of spiral that goes exactly the same but in a reverse way that made me come up with the symmetrical analytical drawing. After that, I decided to develop the balance drawings even further until I came up with movement analytical drawing.

3D PAPER EXTRUSION For the 3 dimensional form, I made up spiral extrusion similar to the movement analytical drawing which are made of triangulars and rectangulars. First of all, I cut the A4 paper in the same width. Then, I folded into three 50% scaling sizes of triangulars and rectangulars. Next, spiral all the big triangulars and rectangulars in one center by 120 degrees angle to form a circle. The biggest size of the triangles and rectangles became the main base. Then stick the smaller sizes to each of them in a higher height. Lastly, tape all the triangles

RECIPE 1. Imagine 5 various sizes of circles from the same center. Plot 3 points that divides them to three parts. 2. Plot 3 spirals from the center to the points on the perimeter twice with a small gap. 3. Divide the surface to 2 parts. 4. Repeat to each circle.

EXAMPLES

Swiss Re Headquarters, 30 St Mary Axe in London, UK This building was designed by Foster + Partners. This building attracts me because of its shape which is very similar to sunflower disk. Its top represents the center of the disk and the pattern follows by Fibonacci sequence. It can also be seen from a distance that the pattern goes spiralling the building all around and as it goes downwards it gets wider. It is similar to my model that it gets wider on the outside. The purpose of the idea in this building is to respond the constraints of the site that it will reduce wind deflections compared with rectilinear tower of similar size. Therefore, this design considers the environment comfort at the ground level.

DEVELOPMENT

3D MODELLING This model extrudes downwards and outwards. It is started from one centre that follows the curve of the arm then it extrudes downwards. In addition, the sizes of the cones are using scaling techniques so that each of them has different sizes. The height of this model is approximately 600mm.

The way I formed this model is by putting all of the top together as one to be the center. Then, spiral the extrusions and curve each of them outwards in different angles.

IDEATION EFFECTS

Elisa Strozyk designed a modern lamp named Miss Maple. The design is very unique due to the material she used which is wooden textile as the skin and steel as the foundation. Thus, she did not use plain surface, but broke it down into grids of triangles. This inspires me to make my model more abstract. I want combine it with another design of lamp that uses diffusion technique which scales as it goes downwards and also uses filtered technique. I plan to make the pattern of my surface spiralling in two ways like sunflower and made of grids to make a textural surface. Moreover, the grids that I want to apply may get bigger as it go downwards.

IDEATION REFLECTIVE

READING

In the Poling reading, he maintains three stages of analytical approach which were very helpful for me in understanding my chosen pattern. The first stage is about simplifying the pattern itself by noticing its characterization of individual parts of the still life and recognizing the repetitive forms, lines, shapes and shading. This helped me to find the Fibonacci sequence on the disk of the sunflower by imagining the path of the disk as dots. The second stage is about finding the tensions in the structure by drawing the linear forms on the pattern, considering the colors and representing the dotted lines. This stage made me able to find the balance of spiral on the sunflower that can be seen clockwise and anti-clockwise. The last one is “translation� which focused on making a more abstract solution by examining the construction limits to lines and tensions between forces that will conclude in a range of concealed constructions and exact expressions. To sum up, these stages really helped me to analyze the pattern carefully and able to find new structures from one pattern. As a result, I came up with a few drawings that each represents movement, balance and symmetry in my pattern. Furthermore, I was introduced to the pattern theory which has a lot of functions such as decorative system, material system, spatial device, static representation and dynamic representation. From the lecture, I realized that all living creatures represent their own pattern. It is related with the Pattern Formation in Pattern by Ball that he maintained how they formed in interactions. This reading helped me finding the idea of the sequence of the seeds in the disk. I did a research and found that they are based on mathematical algorithm which is Fibonacci sequence. Moreover, I followed the seeds on my sunflower pattern by making dots then I found that the amount and movement of the seeds are identical with that formula. According to Biomimicry Guild, Fibonacci sequence works very well in the growth that it will be packed uniformly in the disk. Then I draw a curve from the center until the end of the dots. I found the spiral pattern all over the disk. Biomimicry Guild also maintains that the spiral allows the maximum number of the seeds that it starts from the center and pushes the others outward. Therefore, I made the model bigger as it goes outwards. Virtual Environments


DESIGN ORTHOGRAPHIC

IMAGES

METHOD 1 - Produce contours by tracing profile curves Digitising this model was very complicated due to the branching parts. I used this method only to make the base form of the model and used the paneling tool to make the branches. Furthermore, I used sweep 2 rails command to form this base model which were contained of 2 sizes of circles and one curve. The first circle is located at the top of the handle as the top end of the model. The smaller one is located at the bottom end. This purpose of this hole is to make the 3D panels easier to build. While the curved rail is the spiral movement from the handle that goes bigger in the middle and small in the end.

DESIGN PANELLING

TOOL

First, I made surface domain numbers for the spikes by using 3D paneling tool and offset the points by using point attractor. Thus, instead of just using the point attractor, I decided to use move and scale commands to stretch the points further and wider.

Then, I made pyramid 3D panels and ungroup the 3D panels to delete the surfaces that were not necessary. Moreover, for the handle, I used the 2D paneling tool to make the triangular surfaces. After that I ungroup it to delete the overlapping surfaces individually and fill the gaps manually by using polysurface command.

DESIGN ONE In designing my digitised model, I used 2D and 3D grid paneling tools to make it similar to my clay model. First, I used different number of points to make more pattern on the model. I used tribasic for the 2D panels and pyramid 1 for the 3D panels. Moreoever, to make it easier in joining the 2D and 3D paneling, I used the same multiple number so there will be some points which are overlapped. I also used the offset faces border on the 3D panels to make holes for the light effects. Then, to join them together, I ungroup the paneling surface and delete them one by one. Lastly, when there were some gaps or surfaces which are overlapped, I delete them and make new triangular surfaces manually.

DESIGN TWO Futhermore, I developed my model in the use of offset faces border and number of surfaces in the 2D paneling grid for the second design. In order to develop the variety of the shadow that it would produce, I varied the offset border by using point attractors; so that as it goes downwards the holes will be bigger. Thus, I found that the number of surfaces on the 2D was not really efficient. Therefore, I decreased the number of surfaces so that it would be faster to print and easier to fold.

ALTERNATIVES DESIGN THREE

PARTIAL PROTOTYPE

This time I developed my model further in the 3D paneling. I tried to use the custom 3D grid. It was made of a basic pyramid, but each surface was made of 2 triangulars. On my first attempt, all of the panels were curved which was impossible to be build. Then, I did the triangulate faces so that all the curves became triangulars. Therefore, it turned up to be like the pictures below. In this model, I made the offset border clearer so that it can form a better shadow as well. Thus, similar to the second design, I used fewer number of surface on the 2D panel.

DESIGN PROTOTYPE

ONE

The 3D panels in this prototype represents the spiral of the sunflower pattern. The idea of the scaling trianglar holes also inspired by the pattern that as it goes further from the center, it becomes larger. When I put the light in parallel, the light effects that I obtained were diffused and filtered effects. This corresponds the light effects which I desired from module 1. The use of paper as material brings the possibility for the light to be filtered. In contrast, if I use a thicker material such as mountboard, it may need more techniques to build.

DESIGN REFLECTIVE

READING Thomas Heatherwick in the TED video was really interesting. One of his designs, U.K. Pavilion that won a competition, was inspired by seeds. His idea of seeds which always unseen was very simple that he managed to make and develop it in a very interesting way to express the idea of seed and its growth. This also relates to the analytical drawing by Poling that he noticed the characteristics of one seed instead of everything. Thus, he develop his idea further in more abstract way until he came up with the idea of forming outward projection hairs like the PlayDoh toy. The most interesting is the material for the hair is elastic that in the windy day they can move rhythmically to wind. Lastly, in designing, he did not only concern about the design, but also the lighting, material and function of the building to make a fascinating building. In Scheurer reading about Parameter Space, I found the differences between abstraction and reduction. Abstraction has a little information and complexity but still has a clear picture and not ambiguous. It is divided into three parts which are shape, material and detail. In relation with the lecture, the composition of a form can also be defined as abstraction of shapes which are 1+1=1, sandwich, interference pattern, pun and resolution instead of mesh and nurbs that are maintained in the reading. Moreover, the abstraction of material and detail should be able to create a beautiful optimal design that each component can suit together. On the other hand, reduction is about finding a method to conduct it and rewrite the description without changing it. It is also divided into normalization that terminates anomalies and refactoring that cleaning up a model. This is also related to how Poling introduced me to analytical drawing that we need to simpler the objects in order to develop it further.

FABRICATION

PROTOTYPE TWO

For the second prototype, I revised the outer surface to be a closed surface so that the cables that will be put inside can be hidden. Thus, instead of using point attractors for the offset border, I used the fixed size. The effects for this prototype was not satisfying and need to be explored more. Morever, the movement of the spiral needs to be emphasized more to get the idea back to the sunflower pattern.

FABRICATION

FINAL MODEL

The final model is the final revision for the prototypes. As the previous prototype, the holes were only on the inside part so that I could hide all the cables and LEDs when I did the lighting. Moreover, in order to get a better light effects, I made the holes as a variety of triangular sizes. The scales represents the sunflower disks that goes bigger as it goes outwards. Thus, the spiralling of the spikes is more emphasized in this model in order to show the idea of sunflower spiral.

FINAL MODEL: MANUFACTURE PROCESS Furthermore, I tried to make a small triangulars manually by using polyline tool after I unroll and baked the surface using gumball. Then I delete the offset borders I made and re-make holes manually by using polyline. The pattern I used for my model is a varieties of triangular sizes. As it goes to the smaller surface, it gets smaller. This final model used 7 pieces of 900x600 ivory card 150gsm. The tabs were made by using Grasshopper with 1 cm width and I did some part 2 cm manually to make it stronger.

FABRICATION

FINAL MODEL: LIGHTING

All the lighting cables and batteries I hid them in the handle. I used 2 set of lighting and put them in one switch. The first big set was the light for the spikes which used a 12 volts strip LED and 8 batteries of AA. In order to make the light as a ball, I rolled it on a stress ball and tape it. Before I stick the cable to the battery pack, I attach the handle’s cap in first. This was as the place for the battery pack to be sticked to make the handle construction stronger to hold the batteries.

The second is a small lighting set for the handle it self. I used one lithium battery and one LED to make the handle form the light effect as well. Thus, I make holes on the cap so that the light from the strip LED can also reflected on the handle. Then I put all the cables together and stick them on the handle to go to the top of the handle with the switch as well. Lastly, I put all the surfaces together.

FINAL MODEL

The triangular holes exploded the light effect which is similar to the disk of sunflower. This can be referred as diffused and filtered light effects since the lights come through the holes. It aslo give brightness to the whole surface. Moreover, the variety of sizes also refers to the size of the disk that scales.
