Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional floor scrubber is used to clean floors, then the floor washing function is achieved, but the sterilization and disinfection capability against viruses is lacking
Solution Approach 1:
The patent combines floor washing and air sterilization functions into a single mobile vehicle. The sterilization structure with chlorine dioxide generation system is integrated with the floor scrubbing system, allowing simultaneous or sequential operation of both functions without requiring separate equipment.
Solution Approach 2:
The mobile vehicle is designed to perform multiple functions: floor scrubbing, water absorption, and air sterilization. The sterilization structure can operate independently or in conjunction with the floor cleaning system, making the device versatile for both cleaning and disinfection purposes.
2Reliability
If a sterilization structure with multiple components is added to achieve virus elimination, then the sterilization effectiveness is improved, but the device complexity increases
Solution Approach 1:
The sterilization structure is divided into distinct functional modules: chlorine dioxide storage tank, heating ring for vaporization, fan for air circulation, and control system. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability.
Solution Approach 2:
The patent uses chlorine dioxide as an intermediary substance to achieve sterilization. The heating ring vaporizes liquid chlorine dioxide, and the fan distributes the vapor throughout the space, effectively eliminating viruses without requiring direct contact between the device and contaminated surfaces.
3Reliability
If chlorine dioxide delivery system with heating and aerosol nozzles is implemented, then the disinfection capability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The system uses pneumatic principles where the fan creates air flow to distribute chlorine dioxide vapor. The heating ring vaporizes the liquid chlorine dioxide, and the aerosol nozzles utilize air pressure to spray the disinfectant, simplifying the mechanical components required for delivery.
Solution Approach 2:
The heating ring changes the temperature parameter of chlorine dioxide to convert it from liquid to vapor phase. The aerosol nozzles change the physical state by creating fine droplets or vapor distribution, enhancing the disinfection effectiveness without requiring complex mechanical delivery mechanisms.

Function Achieved in This Case
Effectively washes and sterilizes floors while purifying the air to eliminate viruses like COVID-19, SARS, and Influenza, using a combination of mechanical cleaning and disinfection technologies.
Implementation Method 1
the heating ring heats the stop mesh element to 100 ℃ so as to heat and stop the bacteria and the virus
Implementation Method 2
a front end of the fan is connected with the motor, and a rear end of the fan is coupled with the disinfecting tube
Implementation Method 3
