Abstract

This paper presents an expert system paradigm for mechanical design that allows control within the system to be guided by the function of the final design. A concept of functional attributes, which incorporates ideas from both functional reasoning (Freeman & Newell '71) and planning, is used to characterize an object's function. These attributes are used to guide design through a top down design paradigm. Functional attributes will produce more novel designs than a system doing routine design and are useful for constructing general purpose design systems because they are not domain dependent. DEIMOS, a small general purpose design system, was built to study the use of functional attributes.
