Due to the acceleration of urbanization and the growing demand for tiny houses, modular furniture has become essential for solving living space problems because of its flexibility and efficient use of space. This study integrates the KANO model, AHP (Analytical Hierarchy Process) analysis, and QFD (Quality Function Deployment) to systematically analyze user requirements and guide product design optimization. First, the KANO model was used to categorize 17 user requirements as Basic Quality (M), Performance Quality (O), or Excitement Quality (A). Second, the AHP hierarchical analysis was used to quantify the requirements' weights. The results showed that basic requirements had the highest priority, with "sturdiness," "stability," and "odorlessness" as the core concerns. Finally, the QFD quality house model transformed the user requirements into 17 design functions and determined their weights to provide a scientific basis for design. This study verifies the irreplaceability of essential performance in modular furniture design and enhances market competitiveness through differentiated functions. The research results provide designers with a systematic framework for optimizing resource allocation and focusing on high-value demands. This framework is significant for promoting the industry's high-quality development.
