In order to meet user's demand for a variety of product forms, a new styling design method applied the cellular genetic algorithm and the standard genetic algorithm was presented, which was simulating design thinking characteristic of designers. Firstly, some representative product samples were chosen from the collected samples through clustering analysis, designer focusing analysis and so on. The product styling elements and the quantitative description parameters could be obtained by morphological analysis. Then, setting the representative sample as the initial population, the initial styling design system was built based on the cellular genetic algorithm, which could simulate the design thinking. The intelligent design process was realized, which would generate a large number of innovative solutions with a small original population. Finally, a refining design system was established using the standard genetic algorithm. The conceptual schemes were optimized further and the refinement intelligent design process was realized quickly. The case of cartoon face design showed that this method could effectively support inno- vation design.
