Abstract

A number of design methodologists have developed potentially useful models of design, but few of these models have addressed the full complexity of the design of a real engineering artefact. A joint research programme undertaken at Coventry University and the University of the West of England, Bristol, has identified case-based reasoning as a useful technique for representing engineering design information. A prototype design system has been developed (Vinney et al, 1999a; Vinney et al, 1999b) which operates in the domain of simple mechanical devices. The COnceptual Design ASsistant (CODAS) is capable of generating new design solutions with a controlled degree of novelty. Case-Based Reasoning (CBR) technology was used to store and retrieve past design solutions which were defined in terms of a symbolic representation language.This paper provides a summary of the results from the initial research and development work carried out in the field of mechanical device design and then considers the application of this technique to a complex design problem, that of prosthetic socket design.
