The work aims to propose the construction of a scenario design model based on the theory of scenario design, address the issue of designing finger exercise equipment for middle-aged and young stroke survivors with unilateral finger impairments, specifically for use in office settings as they return to the workplace, and assist rehabilitation enterprises in guiding designers in the design of rehabilitation equipment. The study integrated the scenario design framework with the Analytic Network Process (ANP) and Fuzzy Comprehensive Evaluation (FCE) methods to form a scenario design model for finger rehabilitation equipment. Firstly, a design element framework was established through scenario design. Secondly, through the integration of ANP and FCE methods, the obtained design criteria and elements were weighted, ranked, and comprehensively evaluated to obtain feasible elements for finger rehabilitation equipment in office settings. Finally, through iteration, the feasible criteria and elements were quantified and used to guide case design. By establishing a scenario design model, a finger rehabilitation device is designed. This scenario design model is beneficial for designers to select key design elements, optimize design solutions, and provide better rehabilitation training equipment for patients. It also offers a rehabilitation training equipment design paradigm for enterprises.
