Using computer-generated design aids to facilitate alternative concept embodiments

The objective of this study was to investigate whether the use of computer-generated aids facilitates a greater variety of concept embodiments compared to the classical approach. A total of 60 participants were enrolled in the Design Methodology course. They were divided into a control group using the classical approach and an experimental group in which computer-generated aids were employed. The embodiments produced by the participants from both groups were assessed for variety, independently by two experts having both academic and industrial experience in the field of product development. The experts were not informed about the groups or any of the study details. Analysis of the results of this experiment indicates that computer-generated aids play a supportive role in concept embodiment.
