Further Development

I made the decision to keep developing concept two. What i noticed about the first 1:5 scale model was that it was too hard to determine if the design would be able to hold the minimum load. I decided that I would attempt a 1:1 scale model using two layers of regular cardboard that have been glued together, creating a 10mm thickness to mimic the thickness of the xanita board.

Once i finished the model i soon realised that the design could not withstand the minimum load and other problems began to show. To make the model able to hold the weight i began playing with the idea of slotting in three triangles in the same shape of the main voids (under the seat, the bottom right, and bottom left) to fit tightly within these voids giving the form strength. However, this design would exceed the dimensions of the Xanita board (1500mm, 18300mm).

Another problem was the locking system that i intended to use to keep the two separate triangle pieces together was the dovetail locking system ( shown in esquisse 1) was not strong enough for the design.

The only way i could see this design working was to completely redesign the dimensions, I felt in the end that i was spending more time fixing the design then i would if i were to attempt to make concept one work.
