Prototypes

Prototypes • Why Create a Prototype? • Mock-Up /Presentation Prototype • Functioning Prototype • Examples of EDD Prototypes Sip and Drip

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

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? Images courtesy of Dimension

Functional Prototype A model intended to finalize the operational elements of your invention before it goes into production. Types of Functioning Prototypes • Full Scale Working Model • Scaled Working Model • Partial Model • Virtual Model What form, fit, and function questions can be answered with a functioning prototype?
