Fundamental Study of Function Design of Products

- The Difference between Designed Function by Designers and Emerged Function by Users -

Abstract

Products are created for some purpose, and some parts of the purpose are to create particular functions. This paper discusses the fundamental process to create the functions of artifacts.
In case of a product as an artifact, creators should try to understand the purpose of that, and to make up the concept for that. So it is important to understand the point of design of functions. In this paper, the process of function design is discussed with two view points, from creator's side and user's side. The story to create function structure with creators is completely different from the story on user's side, but there are few discussions about this difference. This paper would point out the most important element to create products that are accepted to many users in the market.
