Research on Innovative Design of Public Facilities Renovation of Abandoned Shared Bicycles Based on Sustainable Design Concept and Kano Model

With the deterioration of the natural environment and the shortage of resources caused by high consumption and high consumption, people begin to reflect on the relationship between human beings and the natural environment. Sustainable design development has become a method and way to solve the contradiction between human society and the environment. Protecting the natural environment and saving resources has become an important factor in current economic development. On the basis of satisfying human needs and aesthetics, design should also start to think about how to design for the harmonious lifestyle of human and the environment, and the idea of sustainable design is born from this. In order to further improve the utilization rate of resources and extend the application value of sustainability, a scheme of transformation and redesign of waste products under the concept of sustainability was put forward. Taking abandoned shared bicycles as the research object, this paper explores the sustainable and innovative design of abandoned shared bicycles. Firstly, the application advantages of sustainable design concept are analyzed by literature analysis. Secondly, the current situation and pain points of shared bicycles are summarized and analyzed. Finally, KANO model is used to analyze user needs and put forward the concrete practice of transforming public facilities with abandoned shared bicycles. With children and the elderly as the main application objects, the transformation plan of public facilities, children's amusement facilities and elderly fitness facilities is carried out, the structure of shared bicycles is disassembled, the focus of user needs is analyzed using KANO model, and the optimal solution is obtained according to the user's demand index. Based on the concept of sustainability and KANO model, the renovation design of public facilities for abandoned shared bicycles not only alleviates the contradiction between resources, environment and human beings, but also provides a new solution to the problems of resource use and resource waste, and enriches the practical connotation of the concept of sustainable design.
