The work aims to sort out user needs and propose a two-child stroller design method which integrates multi-modal balance (VACP), Analytic Hierarchy Process (AHP) and quality function configuration (QFD) to solve the pain points of using strollers for families with two children, such as time-consuming and labor-intensive travel, and the inability to take care of two children. First, the user journey map for two-child travel was extracted through field research and questionnaires. The stroller design needs was quantified and initially screened based on the VACP theory. On this basis, AHP was applied to analyze the need weight and establish the importance of user needs. Then, QFD was used to create the relationship between user needs and quality characteristics, the design elements were aggregated and optimized. The design requirements were clarified and an optimization plan was obtained. Finally, JACK was used to establish a virtual environment for the stroller to verify the rationality of the plan. For the special travel scenarios of families with two children, the seat structure was intended to be adjustable to enhance the safety and convenience of the stroller. Intelligent monitoring and interactive functions could be designed to enhance the interactivity of the stroller. Through JACK simulation, the scientificity of the innovative design solution is verified, and the feasibility of the multi-method integrated design method is confirmed from the side, providing a basis and theoretical innovation for building stroller products.
