The work aims to design a bathroom shelf that can meet the emotional needs of modern consumers under the guidance of the theory of emotional design.Firstly, the advantages and disadvantages of existing shelves on the market were analyzed through market research. Then, under the guidance of the emotional design theory, the corresponding needs of the three levels of consumer emotion were determined, and the AHP was used for weight analysis. Next, the user needs were transformed into technical requirements, and the QFD house of Quality was established to obtain three groups of conflicts. Finally, combined with TRIZ theory, 40 invention principles were used to analyze and solve the conflicts, and the modular design method was used for design practice.The combination of AHP/QFD/TRIZ theory can avoid unreasonable factors in the process of product design and solve problems objectively. Taking the bathroom shelf design as an example, this work proposes the feasibility of applying AHP/QFD/TRIZ theory to the design of similar products.
