Innovative design and evaluation of medical nebulizer for preschool children: A user demand-driven approach

The results indicate that the combined application of UJM, the KJ method, AHP, and FCE can help designers more accurately capture diverse user needs, enhance the scientific rigor and rationality of design and evaluation processes for children's medical nebulizers, and ultimately produce products with higher user satisfaction. This study contributes to the field by providing a systematic framework for the design and evaluation of preschool-aged children's medical nebulizers, offering theoretical guidance and practical reference for future designers.
