Innovative Design of Multi-functional Sanitation Vehicle Based on TRIZ Theory

—In order to bring convenience to sanitation workers and residents and help build smart cities. The innovative method of TRIZ concept is introduced into the design of sanitation vehicle, the method of System & Component Analysis and STC Operator are used to analyze this problem, and then the Technical Contradiction Analysis, and other methods are used to solve this problem. This paper scientifically analyzes various problems existing in sanitation vehicle that need to be improved, obtains a variety of technical schemes, and finally comprehensively analyzes and designs a modular design sanitation vehicle that can be used in a variety of occasions and has a variety of functions. The innovative method of TRIZ theory is used for design, and it also provides method application cases for other products with this demand.
