Why Create a Prototype?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 FunctionForm, 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?
