A Creative Generation Method Solving Design Problems Based on Extenics—Removing the Cigarette Butts on the Ground of Ouzhuang Metro Station as an Example

Idea generation is a key aspect in design, but it is difficult to obtain systematic ideas due to the limited skills of individuals. The method of studying the treatment of contradictory problems in Extenics can provide a reference for solving the problems in design. Taking Ouzhuang metro station in Guangzhou as an example to solve the problem of littering cigarette butts affecting the public living environment, an Extension innovation method is introduced to model the problem with basic elements, and based on the analysis of the actual situation of Ouzhuang metro station, the problem is studied by detailed expansion analysis on multiple basic elements, and using the extension innovation method such as transformation to obtain more than 13 solutions.Finally, the application in a small area of Ouzhuang metro station proved the effectiveness of the solutions. The method can provide new directions for generating systematic ideas for problem solving in design.
