  • Slide 3
  • 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
  • Slide 4
  • Form, Fit, and Function Physical, 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. Images courtesy of Dimension What form, fit, and function questions can be answered with a presentation prototype?
  • Slide 6
  • 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? Types of Functioning Prototypes Full Scale Working Model Scaled Working Model Partial Model Virtual Model
