For a long time, the profession of sanitation workers, as a cleaner of urban garbage, plays a vital role in maintaining environmental sanitation and establishing a good image of the city, but this profession is often ignored and even prejudiced. In addition, with the society's attention to environmental protection, garbage classification has attracted much attention at present. However, many existing sanitation vehicles and sanitation operation methods are still at a relatively primitive stage, and there are problems such as inadequate garbage classification, untidy, and low efficiency. At the same time, these problems also lead to a certain negative inherent impression of the society for sanitation workers., Which has a negative impact on the professional identity of sanitation workers. We have paid attention to these problems in our research and hope to solve these problems through the redesign of sanitation vehicles. (1) Separate division except for a space for placing tools, the space above no cover, the tool can be directly inserted from top to bottom, in addition to taking tools and space cleaning, we designed a door that can be opened from the rear, so that the tool access is more convenient (simple, elegant operation), and to ensure the appearance of neat (modern, not extensive). (2) put the space for storing first aid kits and other items on the top to facilitate users to quickly take them in case of emergency. (3) The garbage bins for storing different garbage are arranged up and down, and can be opened by pressing or kicking, thus avoiding bending over (simple behavior) when opening the lowest space, and facilitating sanitation workers to open the garbage bins with tools in their hands.
