Abstract: To enhance the efficiency of the automatic conceptual design, a new method based on Orthogonal Interactive Genetic Algorithm (OIGA) in form design was proposed. With the extraction and description of the product form features, the genetic convergence speeds were improved by simplifying the solution space orthogonally. Furthermore, the subjective evaluation errors were reduced greatly and the evaluation mechanism was optimized with the integration of the communizing and satisfying fitness function. In addition, the users' fatigues were alleviated on the condition of the interface visualization as the favored features were interactively selected. Experiment results indicated that the proposed OIGA could obtain higher fitness value by less generation times than the simple Interactive Genetic Algorithm (IGA), and it was more feasible and applicable.
