Design Brief: Ehn
A portable stool that is easy to collapse, carry and store in a range of environments
People living in small spaces (i.e tiny homes, vans, etc.)
Ideation, research user testing, prototyping, wood and steel modelling, solid works, and rendering
-Compare portability and collapsibility functions
-Look at existing products and how their mechanisms work
-Initial consideration for form, size, and strength
A series of ideation was undergone to develop working mechanisms, portability aspects and overall aesthetics.
Low fidelity prototypes were used to establish mechanisms, forms, and general functionality aspects like dimensional strength and support structures.
- Legs too high to support weight
-Unstable with dynamic forces
- Different forms and weight distribution
-Different locking mechanisms tested
-Unstable with added weight
- Good dimensional strength
-Use of compression and tension
-Easy to assemble/disassemble
Small works-like models were tested for collapsibility, structure, and dimensional strength.
The final concept makes use of tension and compression mechanisms to hold static and dynamic weight.
A works-like model was constructed out of plywood to gain a better understanding of the forces and mechanisms needed to support substantial weight. It aided in finding areas of improvement for the final concept and model.
How It Works
The final stool is made up of Russian Baltic Plywood, steel, and nylon.It is able to collapse to be flat and easily stored. Its use of tension and compression principles allow for it to withstand weight, while its overall dimensions allow for it to easily transition between different spaces and environments.
