The work aims to study the design ideas and strategies of applying the concept of gamification to "Internet + garbage classification" products, so as to improve and optimize the design and development mechanism of "Internet + garbage classification" products, promote the development of garbage classification and governance in China, and provide valuable references for gamification design research of Internet products. By investigating the current situation of "Internet + garbage classification" products, the paper discussed the necessity of the gamification concept in product design against the existing problems, and summarized the game based levels and design elements of "Internet + garbage classification" products in combination with Norman's emotional design at three levels. Through user research, an in-depth insight into users' willingness and needs to use products was conducted, a gamification design framework for "Internet + garbage classification" products was built, and the design practice of "Campus Qufen Ba" applet was taken as an example to specifically elaborate the game based design strategies and methods of the product. It is proposed that gamification design of "Internet + garbage classification" products needs to start with "integrating internal and external motivations, linking online and offline mechanisms, and optimizing functional content". Optimization design should be carried out for the elements of each gamification hierarchy and organically integrated into each stage of user product use, so as to stimulate and maintain user interest, encourage users to use and continue their use behaviors, and give users a sense of gain, interest and value in participating in garbage classification, so as to effectively enhance the enthusiasm of the public to participate in garbage classification.
