Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional patch-type anti-lightning strike elements are used, then lightning protection capability is improved, but cost increases and heat dissipation becomes difficult
Solution Approach 1:
The patent changes the physical and electrical parameters of the anti-lightning strike elements by using varistors with specific voltage characteristics (first varistor with first breakdown voltage, second varistor with second breakdown voltage) and configuring them in specific circuit arrangements. This allows achieving effective lightning protection with lower-cost components while maintaining proper heat dissipation through the circuit design.
Solution Approach 2:
The patent segments the anti-lightning strike protection into multiple functional parts: a first anti-lightning strike element (varistor) connected to the live wire, a second anti-lightning strike element (varistor) connected to the neutral wire, and a rectifier bridge circuit. This segmentation allows each component to handle specific portions of the lightning surge, improving overall protection efficiency while using more cost-effective individual components.
2Reliability
If anti-lightning-strike elements are added to high-voltage linear segmented LED driving schemes, then lightning protection is improved, but device complexity increases
Solution Approach 1:
The patent merges the anti-lightning strike protection function with the existing rectifier circuit by integrating the varistors into the circuit board that already contains the high-voltage linear drive module and lighting module. The first and second anti-lightning strike elements are connected to the live and neutral wires respectively, and work in conjunction with the rectifier bridge, combining protection and rectification functions in a unified circuit design.
3Reliability
If conventional lightning protection methods are used, then protection effectiveness is improved, but heat dissipation and wiring convenience are compromised
Solution Approach 1:
The patent applies local quality by positioning the first anti-lightning strike element specifically on the live wire side and the second anti-lightning strike element on the neutral wire side, with each element having optimized electrical characteristics for its specific location. This localized optimization ensures effective protection while maintaining simple wiring connections and proper heat dissipation paths for each component.
