Abstract

This study aims to accurately identify and synergistically balance multi-stakeholder needs to enhance waste sorting efficiency and user engagement. Methodologically, an improved KJ method was adopted to construct a tripartite needs alignment framework, yielding a standardized requirement inventory. Based on KANO theory, a bidirectional questionnaire was administered to compute Better-Worse coefficients for need classification and prioritization, followed by the development of a gamified collaborative design mechanism to interconnect the three stakeholder groups and inform the APP design. The findings delineated the functional requirements of waste collectors, recycling merchants, and child users, which were subsequently integrated via a dynamic priority matrix and translated into design elements, culminating in a coherent design scheme that demonstrably improves sorting accuracy, accelerates recovery-reproduction workflows, and broadens public access to classification knowledge. The integrated KJ-KANO and gamification-based approach effectively curtails subjective design bias, enhances objectivity through the triangulation of needs clustering, classification, and systematic design, and facilitates dynamic need equilibrium via gamified collaboration—thereby enabling more efficient and precise multi-party coordination. Moreover, it offers a reusable methodological framework for stakeholder-oriented design and contributes meaningfully to the promotion of sustainable, green lifestyles.
