Dining Table Design Research Based on User Needs Hierarchy and DEMATEL-ISM

Abstract

This study aimed to address the demand for furniture by developing a user-oriented design pathway for intelligent furniture products, using dining tables as a case study. According to Maslow’s hierarchy, the user needs are classified, and then the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was used to calculate the causal relationship, as well as the centrality and weight of each demand. The logical relationship between these factors was analyzed with Interpretive Structural Modeling (ISM) to create a hierarchical logic diagram. To ensure the feasibility of the theoretical framework, the System Usability Scale (SUS) was used for evaluation. This study systematically sorted out the logical relationship and hierarchical structure in the table demand system and identified the core elements and factor categories in the table design. The results confirmed that this design pathway effectively met user needs for dining furniture and provided practical guidance for developing the same type of furniture products, offering valuable reference for similar design endeavors.
