Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional UV LED sterilization device is installed, then sterilization function is provided, but internal volume of the product is reduced
Solution Approach 1:
The patent combines the UV LED sterilization module with the existing lighting module into a single integrated structure. The UV LED is mounted on the same substrate as the lighting LED, eliminating the need for separate installation space and electronic components, thereby maintaining internal volume while providing sterilization function
Solution Approach 2:
The lighting module is designed to serve multiple functions: general illumination and UV sterilization. By integrating the UV LED into the existing lighting module, the system achieves multi-functionality without requiring additional dedicated space for sterilization, thus resolving the volume reduction problem
2Reliability
If additional electronic devices are added for UV LED control, then sterilization function is enabled, but volume within the sterilization device is reduced
Solution Approach 1:
The control circuit for the UV LED is integrated into the existing lighting module's substrate, sharing the same electronic infrastructure. This eliminates the need for separate electronic devices and mounting space, thereby preventing volume reduction while enabling sterilization function
