Green Design of Prefabricated Community Control Measures in Response to Public Health Emergencies

During the COVID-19 pandemic control, all communities in China were gated and under strict management, which was highly effective in preventing the spread of the pandemic. Based on the questionnaire and combined with prefabricated green design, TRIZ is introduced to transform the problems, and the innovation points and solutions of prefabricated community control measures are proposed by using the contradiction matrix. The paper summarizes situations of community control during the COVID-19 pandemic in China and concludes the problems such as poorly constructed temporary roadblocks, rapid increase of traffic pressure, and inaccessible public spaces in the community. Prefabricated community control design focuses on transportation-oriented community control. Based on TRIZ inventive principles, prefabricated design approaches for gate control and public access control are proposed, which gives communities the resilience to respond to public health emergencies while retaining an open characteristic on a daily basis.
