The concept of product design in the twenty-first century is based on people’s demands. User’s sensory cognition has profound influence on the product experience. To tap the market potential and help designers understand customers’ deep-seated emotional needs, it is necessary to investigate the link between users’ sensory cognition and products. The study aims to delve into users’ emotional needs for health kettles and convert these demands into detailed design specifications. It also aims to improve the product design and increase user satisfaction by investigating the correlations among users, product experts, and designers. By providing more precise research methods, designers may more accurately capture and meet users’ emotional needs. First, the study adopted the KANO model to extract product requirements from the users’ perspective. It divided the needs into different levels. Subsequently, it used the Analytic Hierarchy Process (AHP) model to further analyze, from the expert’s perspective, the needs’ technological feasibility and market feasibility, etc. It established a demand list with different weights. Finally, the study used Kansei Engineering to correlate user needs with product design elements to obtain the most suitable elements for consumers. This research created a reasonable and comprehensive design scheme that ranged from the exploration user need, the expert’s feasibility evaluation, to the extraction of design elements. The combination of the KANO, AHP, and Kansei Engineering models can better uncover users’ needs while assessing the feasibility of the needs in advance, providing designers with appropriate design elements and new insights for innovative product design.
