Nature of Rapid Proof-of-concept Prototyping

Abstract

Rapid prototyping, usually synonymous with stereolithography, is seen as a key enabling technology in the product development process. This paper takes a broader view of rapid prototyping for proof-of-concept, as it applies to mechanical systems design. It uses a case study of the design of a pineapple harvester to explore the place of various physical prototyping media in the rapid development of solution concepts. This analysis leads to a multi-faceted characterization of the act of prototyping as problem solving, as exploration and serendipity, as process and as sharing. Prototyping is a site for collaboratively considering issues, leading to a rapid resolution of design naïvete. It is concluded that proof-of-concept prototypes can be used at any stage of the product development process.
