The success of ideas for solving local problems depends more on accurately identifying on-site issues and verifying them in a usable form than on the flashiness of technology. Local youth personally selected the challenges facing Busan, such as safety in child protection zones, waste shell disposal, algae recycling, and tourism congestion. Seven teams designed solutions using a living lab approach and produced minimum viable products to verify their commercialization potential. The iGuard team, which combined intelligent CCTV with airbag-type safety facilities, received the highest evaluation and was awarded the Mayor of Busan Award. Busan Metropolitan City and the Busan Center for Creative Economy and Innovation held the 'Campus Living Lab Local Problem Solving Idea Contest Final Evaluation Meeting' at Hanwha Resort Haeundae on the 27th. This contest was organized as part of the '2026 Smart City Living Lab Operation Activation Project.' It supported university and graduate students and prospective entrepreneurs in the Busan region to identify local problems experienced in their daily lives and to develop solution ideas and business models using the Living Lab. A living lab is a method in which local residents, users, and experts identify problems and experiment with solutions in real-life spaces. Participating teams moved beyond the stage of proposing ideas to reflect user and on-site needs, and tested feasibility by creating a Minimum Viable Product (MVP). Seven teams selected through preliminary rounds participated in the final evaluation. Each team presented the causes of local problems, solutions, technology configurations, expected users, and commercialization plans, and introduced the prototypes and service models they had developed. iGuard, selected as the best team, proposed the 'Intelligent CCTV-linked School Zone Airbag Fence.' It is a solution that protects pedestrians from the risk of vehicle accidents by connecting intelligent CCTVs in child protection zones with airbag-type safety facilities. Existing school
