Investigation into the Comfort of Automotive Seating through the Integration of Affective Engineering Design

Applying ergonomics theories to analyze the postures of vehicle occupants and leveraging the principles of affective engineering and Analytic Hierarchy Process (AHP), we design the form of comfortable car seats to meet both the physiological and psychological needs of the occupants. Initially, through market research, we systematically analyze the different postures of the human body in the vehicle under various conditions, and the changes in the physical state of the occupants during vehicle operation. This analysis informs the design of safe seats that conform to ergonomic postures. Subsequently, we embark on affective engineering design for car seats. A broad collection of car seat forms is compiled, with the KJ method employed for classification evaluation. We assemble a dataset of car seat-related images and select appropriate affective vocabulary. Using the Analytic Hierarchy Process, we conduct affective evaluations of the car seats, analyzing the association between affective words and car seat design. Ultimately, combining the theories of ergonomics, we calculate the form of comfortable car seats.
