A Creative Generation Method of Product Design Based on Extenics and TRIZ — Taking the Design of Mobile Phone Charger as an Example

In order to improve the efficiency of producing new product ideas and the decision-making in evaluating and selecting the best solutions scientifically, the method of generating product design ideas is refined by integrating Extenics and TRIZ. Firstly, an extension model is established by using the basic element theory to obtain the starting point of product innovation, and then through the cross analysis of technical parameters, invention principles of TRIZ theory and extension analysis and extension transformation methods of Extenics, the specific creativity of the product is obtained. Finally, the evaluation and optimization of the obtained product creativity are carried out by using the optimization evaluation method, and the creativity that meets the needs is selected, and the innovative design scheme of the product is formed. Taking the design of mobile phone charger as an example, a lot of design ideas are obtained and the effectiveness of the refined method proved.
