Abstract: In order to enhance the efficiency and quality in product imagery design, an auxiliary
method of simulating the design thinking process is proposed. Through the experiment on conception
of the product imagery, the designer’s design thinking is analyzed. The design activity can be divided
into three parts: analyzing proposition, generating creative solution and optimizing creative solution.
For the key node strategy, the corresponding simulation model is established using AHP, directed
similarity method, approaching ideal solution, neural network, genetic algorithm and so on. Finally,
the effectiveness of the method is verified by the design scheme of the retro-styled faucet.

Key words: design thinking, process simulation, imagery, design method
