Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mercury lamp is used for UV sterilization, then sterilization function is achieved, but environmental pollution occurs due to mercury content
Solution Approach 1:
The patent extracts and eliminates the harmful mercury component from the sterilization system by replacing the mercury lamp with a mercury-free UV light source, thereby maintaining sterilization functionality while removing environmental pollution risks
Solution Approach 2:
The patent employs a disposable or replaceable UV light source module that can be easily replaced when depleted, avoiding the need for complex mercury containment and disposal systems while ensuring continuous sterilization effectiveness
2Reliability
If a mercury lamp is used for sterilization, then sterilization occurs through ozone generation, but sterilization efficiency is limited due to beam angle issues
Solution Approach 1:
The patent employs a reflector structure that dynamically directs UV light rays through reflection to achieve uniform distribution across the sterilization area, overcoming the limited beam angle of conventional lamps and enhancing sterilization efficiency
Solution Approach 2:
The patent introduces a reflector component that redirects UV light in multiple directions, transforming the unidirectional beam into a multi-dimensional light distribution pattern that covers the entire sterilization chamber more effectively
3Reliability
If a sterilization module is designed with waterproof requirements, then waterproof performance is improved, but device complexity increases
Solution Approach 1:
The patent employs a waterproof shell or coating that encapsulates the electronic components and light source, providing effective waterproof protection through a simple external barrier rather than complex internal sealing mechanisms
Solution Approach 2:
The patent divides the sterilization module into separable waterproof sections, allowing each component to be independently sealed and assembled, thereby achieving waterproof performance through modular construction rather than monolithic complex sealing
4Adaptability or versatility
If a sterilization device is embedded in specific appliances, then adaptability is improved, but ease of manufacture and integration becomes more difficult
Solution Approach 1:
The patent designs a universal sterilization module with standardized mounting interfaces and dimensions that can be adapted to various appliances such as refrigerators, water purifiers, and humidifiers, simplifying manufacturing and integration across different product lines
Solution Approach 2:
The patent pre-configures the sterilization module with standardized connection interfaces and mounting features during manufacturing, allowing for easy installation and integration into different appliances without requiring complex customization for each application
