The work aims to explore the community mutual aid model derived from the Circle community network system and summarize the functional requirements of traditional design and collaborative innovation design for collaborative designers. The design models of the Circle community network system are analyzed by examining the process and stakeholders of the Circle service system from three levels of diverse stakeholders, conceptual derivation, and model thinking. Based on this, the design strategies of community collaborative and mutual aid models are constructed from three levels of behavioral identity, emotional interaction and experiential value and the functions of collaborative designers are expanded to: speculative design thinking, interdisciplinary knowledge system, ability oriented design, and collaborative innovation. The community collaboration and mutual aid model derived from the Circle social network system can to some extent guide and optimize the elasticity and resilience of localized communities, and continuously develop towards a direction more conducive to social innovation models.
