In view of the homogeneity and lack of characteristics in the form design of the heating equipment with frequency conversion electromagnetism, the research was carried out with the re-design method. Firstly, the emotion requirements of users, enterprises and market were investigated, and the product styling re-design was positioned; Then according to the target position, the styling of the representative products was selected to be analyzed, and the key design elements were extracted; Finally, according to the practical situation, the key design elements were integrated and innovated, and a kind of new product form was re-designed subsequently. The research shows that the scheme selected by the enterprise meets the actual demand, and the re-design method can effectively improve the quality of product form.
