In addition to their practical and aesthetic qualities, ceramic teapots are highly decorative and stylish. Based on the theory of perceptual engineering, this study employs eye-tracking technology and semantic-difference methods to investigate user preferences for ceramic teapot shapes. Using eye-movement experiments, the study first determines users’ visual attention to different morphological regions. Using the orthogonal alignment method, nine styling samples were developed by combining expert classification of classic and traditional teapot styling elements. By combining a semantic perception questionnaire with a satisfaction questionnaire, the study evaluated users’ visual attention to these samples and their satisfaction with them. It was found that shapes characterized by classic, rounded, and proportional coordination were more in line with consumers’ aesthetic preferences despite the differences in semantic evaluations among consumers of different genders and ages, which led to relatively consistent consumer satisfaction. The purpose of this study is not only to provide a scientific basis for styling ceramic teapots but also to assist designers in grasping the laws of consumer preference in order to create better products.

Bamboo furniture, as an emerging low-carbon industry, has become a significant component of the furniture sector’s sustainable development. To identify the key design elements of bamboo furniture and evaluate their importance, this study employed a combination of the Knowledge Creation Model, text mining, the Analytic Hierarchy Process (AHP), and Quality Function Deployment (QFD). The SECI knowledge creation model was utilized to establish the process framework. BERTopic was applied to analyze online bamboo furniture reviews. Key user needs were extracted using AHP. A QFD matrix was constructed to transform these needs into design elements and technical attributes, determining the weights and rankings of the design factors. The findings revealed that safety, comfort, and ease of use are the most critical factors for users. Safety is a core element throughout the product lifecycle. Enhancing bamboo furniture engineering attributes, including improving connector performance, selecting durable materials, and incorporating ergonomic design, is key to enhancing product safety and extending its lifespan. This study provides valuable insights into design elements to prioritize in bamboo furniture product development. This contributes to improved design quality and promoting sustainable growth of the industry.
