Question
Name the five things a physical prototype is used to test.
Answer
Scale, aesthetics, materials, function and performance.
Question
How is a function prototype usually built, and why?
Answer
As the mechanism alone in a rough open frame. It is quick to build, and testers comment on whether it works rather than on how it looks.
Question
Why test candidate materials in identical geometry?
Answer
So the comparison is fair. If the shapes differ, any difference in feel, stiffness or finish could come from the shape rather than the material.
Question
What does a performance prototype test that a function prototype does not?
Answer
What happens over time — wear, heat, fatigue and the failures that only appear after thousands of cycles.
