Taking the background of global epidemic prevention and control as inspiration, the paper aims to research the seating of waiting room in the social background of the new era, use the collaborative and participatory concept, qualitative and quantitative way to study the needs of all users, and establish an evaluation index system, so as to complete the redesign of the seating of waiting room. Based on the concept of social innovation and the waiting room chair, resource and demand are coordinated, and requirement data is captured through data search and expert advice. Combined with subjective evaluation AHP and objective evaluation entropy method, the demand indicators of passengers, operators and producers are analyzed at multiple levels, and the priority of indicators is determined to guide the design. The optimal weighting method combining subjective and objective can effectively avoid the excessive subjectivity of the design decision of the analytic hierarchy process, which may lead to the unconvincing evaluation results. Through the concept of participatory and collaborative social innovation, issues of privacy, comfort and promotion of epidemic prevention in the new social context are realized.
