Why Create a Prototype?• If a picture is worth a

thousand words, how much is a prototype worth?

• Identify flaws, inefficiencies, and design alternatives

• Gauge reactions from potential customers, buyers, or investors

Form, Fit, and FunctionPhysical, functional, and performance characteristics or specifications that uniquely identify a component or device and determine its interchangeability in a system

Form: The shape, size, mass, weight, and other visual parameters which uniquely characterize an item.

Fit: The ability of an item to physically interface or interconnect with or become an integral part of another system.

Function: The action or actions that an item is designed to perform.

What aspects of form, fit, and function are important to your design?

Fertigator

Mock-Up/Presentation Prototype

A three-dimensional representation of your invention that offers greater visual impact than a drawing would provide.

What form, fit, and function questions can be answered with a presentation prototype?

Functional Prototype

A model intended to finalize the operational elements of your invention before it goes into production.

What form, fit, and function questions can be answered with a functioning prototype?
