Express: Brainstorming sessions generate as many product concepts as possible.
Test: The prototypes are shown to users for feedback. Some of these are shown in the pictures to the right. I constructed and tested over a dozen prototypes.
Cycle: The feedback is used as an input for new brainstorming sessions.
Final prototype
To the right is a picture of the final prototype before industrial production. It is made using rapid prototyping techniques: laser cutting, heat forming.
