Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disinfectant is sprayed on the mobile device surface, then the disinfection effect is improved, but the screen may be damaged and carrying a disinfectant bottle is inconvenient
Solution Approach 1:
The patent replaces the mechanical/chemical disinfection method (spraying liquid disinfectant) with a microwave-based sterilization system. The microwave sterilization device emits microwaves that are converted into heat by a heat conversion layer, creating a high-temperature environment that kills bacteria without requiring liquid disinfectants, thereby avoiding screen damage while maintaining effective disinfection
Solution Approach 2:
The patent introduces a heat conversion layer as an intermediary between the microwave sterilization device and the mobile device surface. This layer absorbs microwave energy and converts it to heat, which then sterilizes the surface. Additionally, a protective layer is introduced to protect the screen from direct exposure to high temperatures, allowing effective sterilization while preventing screen damage
2Reliability
If disinfectant is sprayed on the mobile device surface, then the disinfection effect is improved, but carrying a disinfectant bottle is inconvenient
Solution Approach 1:
The patent merges the sterilization function directly into the mobile device by integrating a microwave sterilization device within the device housing. This eliminates the need for separate external disinfectant bottles and manual application processes, allowing users to sterilize the device surface simply by activating the function through the processor control
Solution Approach 2:
The patent implements a self-service sterilization system where the mobile device sterilizes itself. The processor detects when sterilization is needed and automatically activates the microwave sterilization device, which heats the heat conversion layer to kill bacteria on the device surface, eliminating the need for user intervention with external disinfectants
3Reliability
If microwave sterilization is used, then the sterilization effectiveness is improved and screen damage is avoided, but device complexity increases
Solution Approach 1:
The patent uses thin film structures for both the heat conversion layer and the protective layer. These thin films are integrated into the device housing and screen assembly, minimizing the additional space and material required while providing the necessary functional layers for microwave sterilization and screen protection
Solution Approach 2:
The processor serves multiple functions: it controls the display, manages device operations, and now also controls the microwave sterilization device. By utilizing the existing processor for sterilization control, the patent avoids adding a separate dedicated control unit, thereby reducing the increase in device complexity
