IDEA GENERATION IN CONCEPTUAL DESIGN
Creative idea generation is a vital part of the engineering and the new product development process. This paper is based on a number of studies which have analysed idea production during brainstorm sessions and has led to the provision of a new method by which to analyse the ideas produced. Real engineers, design tasks and design processes are analysed for ideas and evaluated objectively in terms of the actual concepts formed by the ideas. It was found that the rate of idea production appeared to be constant throughout each session until roughly 60mins. The results showed that over half the appropriate ideas of the session are produced within the first 10 minutes and the majority of the ideas behind each concept are provided by 20mins.
