Prototyping
Why Prototype (or Model)
Convey a concept to anyone
Prove out a concept (how it works)
To scale or not
Show an appearance model to potential customers, manufactures, investors, etc.
Get feedback from users, designers, manufacturing, etc.
Learn about the current design
Size evaluation – in it’s environment
Short run preproduction – evaluate final design (customer feedback and final tweaks, prove out tooling designs, test
Analyze with CAD/CAM tools/software for clearances, fits, interferences, strength, thermal properties, moldability, manufacturing, rendering, etc.
Don’t – provide a sketch or an illustration and/or a sell sheet

Prototyping
Types - Definitions from Wikipedia
A Proof-of-Principle Prototype explores some functional, but not all, aspects of the intended design.
A Form Study Prototype explores the size and appearance, but not the functionality, of the intended design.
A User Experience Prototype captures enough aspects of the intended design that it can support user research.
A Visual Prototype captures the size and appearance, but not the functionality, of the intended design.
A Functional Prototype captures both function and appearance of the intended design. It may be created in with a different method and scale from final design.
Generic Names
Breadboard – How it works
Sketch – Simple form study
Appearance – Looks very close to real thing, but doesn’t function
Fully functional Prototype – Looks like, works like
Virtual – 3D CAD
