EARLY EXPLORATION
My aim was to create a component that will not use a lot of material through folding steps, increases rigidity and that is able to withstand the application of compression force in multiple directions, and become structurally stable. I begin with a symmetrical cross shape by curving two legs inwards across each other, while the other two outwards. The legs are interlocked in the center of the plane using the technique of intersecting. Further, the component was simplified as shown in illustration 2.3, using the same intersecting method as in the first component.

COMPONENT CONSTRUCTION The component begins with a square of paper, cut into the strip with two legs. I curved the legs inward where they intersected in the plane. After exploring with the legs and changing the shape, I realized that the center plane was not offering support. To increase rigidity, I compined two components together on top of each other. Thus, I was able to create a more rigid component, allowing this final component to distribute force.
MATERIAL PASS AND FAIL In the first exploration, I used paper, which was flexable and easy to work with, but it was very weak. In the second exploration, I used chipboard, it was rigid, bur it wasn’t flexable enough to create the curves in the legs. In the third method, I created my component using bristol paper. It was strong and flexable.

FORCES AND REACTIONS
The force applied would be on from the top of the component while standing on all four legs. The forces would be displaced through the legs and the center.

ABSTRACT GEOMETRY
The abstract geometry of the component results in triangle, which are combined to create a square. Local pattering is connected by several components. The pattering continues into a regional pattering.

LOCAL PATTERING
The first local pattering of the component begins with the bottom leg intersecting with the top leg of the two components . Two other components are connected perpendicularly with the other legs. This local pattering can be connected horizontally or vertically.

REGIONAL PATTERING The regional patterning is constructed from the local pattern with diagonal connections of the legs on each side. As in a single component, the compression forces are distributed through the assembly.

LOCAL PATTERING
The second local pattering of the component begins with each leg combined with the top, bottom, right and left leg of the components . The other components are connected horizonatally and vertically with the other legs shown in blue in Figure 8.5. By removing the legs plane, we result with multiple single strips. 8.5 Each leg rotated 90 degrees.

THIRD COMPONENT CONSTRUCTION The component begins with a square of paper, cut into multiple strips. I folded the single strips inward where they intersected in the center. To increase rigidity, I intersected the two strips together on top of each other. Thus, I was able to create a more flexible local pattering, allowing it to stretch and compress in horizontal and vertical directions. MATERIAL PASS AND FAIL In this exploration, I used chipboard, which was flexable and easy to work with. In the second exploration, I used vynal, it was flexible, but it was to flimsy, which created slipping between the intersecting points.
