Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If capacitors are mounted using surface-mount technology or through hole technology, then the electronic circuit achieves stable operation, but the replacement of broken capacitors becomes troublesome and difficult requiring specific tools
Solution Approach 1:
The patent divides the capacitor assembly into a modular structure where the capacitor is mounted on a separate circuit board that can be detached as a complete unit. This segmentation allows the capacitor to remain securely mounted (maintaining reliability) while enabling easy removal of the entire circuit board module (improving repairability) without requiring individual capacitor replacement tools.
Solution Approach 2:
The patent extracts the capacitor from the main device housing by mounting it on a detachable circuit board that can be removed as a separate module. This extraction allows users to access and replace the capacitor without disassembling the entire device, significantly reducing repair difficulty while maintaining operational stability during use.
2Volume of moving object
If capacitors are integrated within the device housing, then the device achieves compact structure, but the replacement process becomes time-consuming and complex
Solution Approach 1:
The patent segments the capacitor assembly into a detachable circuit board module that maintains a compact integrated structure during normal operation. The circuit board with the capacitor mounted on it forms a self-contained unit that can be quickly removed and replaced, reducing maintenance time while preserving the compact design of the overall device.
3Reliability
If capacitors are mounted on electronic circuits using fixed mounting methods, then the electronic circuit achieves stable operation, but the replacement requires detaching from the circuit board making it troublesome
Solution Approach 1:
The patent segments the capacitor mounting structure into a detachable circuit board that can be removed as a complete module. The capacitor remains firmly mounted on the circuit board ensuring stable operation, while the circuit board itself can be easily detached from the device housing, making replacement simple and trouble-free without requiring users to work with individual capacitor connections.
