Abstract

At conceptual design stage, designers often tend to be restricted by general stereotypes and by their previous design experiences. Consequently, this paper proposes a constraint-based cooperative interactive design method, in order to combine human intelligence and computer intelligence for product design. The model of constraint based human machine cooperative interactive design system is described, how to realize the human machine cooperative interactive optimal search by genetic algorithm (GA) is discussed in detail. In design process, GA is employed to search for a near-optimal design, and a trained neural network is used as a fitness function. Finally, A mould injection structure design is chosen as the subject of the current investigation.
