To solve such problems as time-consuming and labor-intensive traditional manual disinfection of escalators, difficult sterilization and disinfection at every moment, and incomprehensive disinfection. First of all, with the user evaluation method, it is concluded that reliability, functionality, operability, efficiency, layout rationality, friendliness, trust, environmental protection, and aesthetics are the main demand elements of escalator disinfection products. Secondly, the PUGH matrix selection method is proposed, which provides an effective evaluation tool for the selection of product design schemes and obtains the optimal design scheme from these three design schemes through cautious selection. Finally, design and improve the core modules of product solutions, the product idea is visualized in three dimensions, and the prototype is printed with light-curing 3D printing technology. The disinfection effect of the product is fully experimented and studied by ATP fluorescence detector, and the practicality and feasibility of this study are verified by user evaluation method. The proper use of this product provides a reasonable device for the improvement of escalator disinfection effect, which can more accurately meet the needs of escalator disinfection.
