Esquisse 4

I worked with Claire and Lou to develop our chair design. We began by sketching out some ideas and making some quick paper mockups. We finally settled on a design formed by three triangular forms that make a chair with a low back rest.




Our 1 to 2 model was made in rigid black card, and enabled us to better develop the closing mechanisms and proportions of our final model.




Different tabs and insertions were developed at this stage to best attach the three triangular forms in this central articulation.



Cutting the 1 to 1 version required careful eye hand coordination in order to avoid cutting through to the floorboards. The cardboard we used carried heavy folds and cuts from its former life as packaging, making weaknesses in the otherwise sturdy product.



In order to give the chair much needed internal support, we added some upright profile elements as fins that give rigidity to the triangular forms.




Our resolution in all its glory. Although it has inherent structural dilemmas still to address, the chair has potential to be developed.

Esquisse 3 - Weight bearing structure

This week's task involved creating a load bearing object, h200mm, with a locking system, capable of supporting 100kg. It was challenging to find a resolution that both locked and provided the required strength. Triangulation proved to be a reliable structural solution.

My finished object


Design sketches. This final version was only arrived at via a path of folly and several failed ventures.


This is part of the toblerone adoration series


I call this woeful experiment my baby giraffe


I began making a mock up of the final in paper, in an attempt to visualise the structure in its actual form


Structural elements criss cross across the loadbearing plate, slotting into each other for a stable core


Side flaps are inserted on an upward angle. In future, I would double up this flap in order to make a sturdier insertion into the structural elements


And voila! A weight bearing structure! 100kg? We'll see tomorrow...
