Research on willow furniture design based on Kano-AHP and TRIZ

Willow wood furniture has become one of the most popular types of wood furniture in the Chinese furniture market. Research was undertaken to solve the pain points of product design and meet the requirements of green development. Firstly, the Kano model was used to classify user requirements. Secondly, the Analytic Hierarchy Process was used to calculate each design factors’ comprehensive weights, ensuring consistency between the design objectives and user requirements. Thirdly, the TRIZ contradiction matrix was used to identify and solve engineering difficulties in the design process. During the design process, the Kano-AHP-TRIZ was combined to realize a scientific design strategy that combines qualitative and quantitative approaches. The results showed that the design scheme of willow furniture based on user requirements had consistency, matching, and effectiveness with the furniture market development trend, which makes the furniture design process more scientific and rigorous. It also provided a new research perspective and design strategy for the innovative development of the furniture industry.
