Research on User Needs Elicitation and Product Iteration Strategies for Home Postpartum Pelvic Floor Rehabilitation Devices Based on the Hybrid KANO-DEMATEL Model

Abstract

Abstract—Facing the universal trend of moving postpartum pelvic floor dysfunction (PFD) rehabilitation to home environment while "technology stacking" conflicts with user compliance, this paper offers an integrative hybrid demand framework from a joint perspective between users and technology — Kano Model & DEMATEL method integrated. In order to obtain at the 23 key design attributes, a multi-source existing data fusion. The Kano Model was used to categorize the non-linear aspects of requirements, and DEMATEL technique was employed for decomposing causal relations among these characteristics. Findings uncover an exclusive linkage mechanism: "physical safety= psychological compliance", proving that cognitive features and property attributes like the present solidity are thereby a source of causality leading investigations generate long-term individual commitment, whereas biofeedback visualization acts as breakpoint feature in alleviating user-centred cognitive stress syndromes. Results Through the analysis and evaluation of customer priority index (CPI), this study summarize a 3-stage iteraction product iteration strategy that including "trust-building phase", "visualization implementation phasel" adn emotional empowerment phase. Originality/value This study overturns the conventional linear relationship of user demand, thereby providing theoretical support and practical path for accurate transformation from “function-oriented” development to “experience-oriented” one in domestic household medical device enterprises.
