Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the output signal is transmitted through multiple circuit boards (transformer to synchronous rectification board to power supply main board to golden finger board), then the signal can reach the external apparatus, but the transmission path becomes long causing significant energy loss
Solution Approach 1:
The patent merges the synchronous rectification board and golden finger board into a single integrated circuit board. The synchronous rectification module and conductive contacts are both mounted on the same board, eliminating the need for separate golden finger board and reducing the number of inter-board connections. This integration directly shortens the signal transmission path from the transformer to the external apparatus, reducing energy loss while maintaining functional separation between rectification and connection functions.
Solution Approach 2:
The patent segments the power supply system into distinct functional modules: the transformer, the synchronous rectification module, and the integrated circuit board containing both the rectification circuit and conductive contacts. This modular segmentation allows for optimized signal paths within each module while reducing the need for signals to traverse multiple separate boards, thereby reducing transmission loss.
2Ease of manufacture
If multiple circuit boards are used (synchronous rectification board, power supply main board, golden finger board), then each board can be optimized for its specific function, but the overall structure becomes complex and costly
Solution Approach 1:
The patent combines the golden finger board function with the synchronous rectification board into a single integrated board. This merging eliminates the need for separate golden finger board while maintaining the synchronous rectification functionality. The integrated board reduces structural complexity, decreases the number of connection pieces required, and lowers overall manufacturing costs while preserving functional optimization through proper layout design.
Solution Approach 2:
The integrated circuit board serves multiple functions simultaneously: it acts as both the synchronous rectification board and the golden finger board. The board incorporates both the synchronous rectification module and the conductive contacts, making it a multi-functional component that replaces what were previously separate single-function boards, thereby simplifying the overall structure.
3Ease of repair
If the conductive contact is provided on a separate golden finger board, then the maintenance process is simple, but the number of connection pieces increases and installation becomes complex
Solution Approach 1:
The patent merges the conductive contacts with the synchronous rectification board into a single integrated unit. This eliminates the need for separate golden finger board and its associated connection pieces. The integrated design simplifies installation by reducing the number of components to be assembled and connected, while maintaining the ease of maintenance benefit through modular design that allows the entire integrated board to be replaced or serviced as a unit.
