The user's requirements for product design include descriptiveness, dynamics, and personalization. The insufficient mapping of User requirement knowledge seriously affects the accuracy of designers' grasp of design ideas and design knowledge. For this issue, we proposed a design knowledge perception and representation method for user requirements. Design knowledge from user requirement question and answer (Q&A) was extracted, including design theme, design content, and design evaluation to improve communication efficiency between designers and users. A representation method was proposed for User requirement knowledge based on the Q&A of the user's initiating requirements and the product provider's solutions. A design requirement framework for expressing design intent was proposed by perceiving dialogue context. Furthermore, the rule of design requirement was derived based on attributes in User requirement knowledge for designers. Finally, the knowledge perception, representation method, and knowledge framework of air conditioners were analyzed to determine the knowledge rules. The results indicated that the knowledge perception and representation method proposed in this study accurately reflected User requirement knowledge and provided sufficient knowledge for product design. At the same time, the extracted design requirement was shared among different decision-makers, providing a theoretical basis for group decision-making.
