In home-based elderly care, nursing beds play a crucial role in the daily lives of older adults. However, most existing nursing beds are designed for general patients, neglecting the specific needs of people with disabilities and their caregivers. To enhance user satisfaction with nursing beds, this study proposes a conceptual design approach based on a KANO-AHP integrated model based on behavioral design. First, the needs of caregivers and people with disabilities are identified through behavioral observations and in-depth interviews. The Fogg Behavior Model is then applied to translate these behavioral insights into extractable design elements, which are subsequently classified and prioritized systematically using the Kano model. Subsequently, the Analytic Hierarchy Process is employed to screen the most critical needs from the extracted ones and transform them into key design elements, thereby defining the structural components of the product. This integrated approach enables an accurate mapping from user requirements to design elements, thereby facilitating the development of nursing beds for people with disabilities. This study demonstrates the feasibility and effectiveness of the KANO-AHP model in design research for the aging population, offering valuable guidance and an innovative perspective for nursing bed design.
