Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cables are used for signal transmission and power supply between modules or boards, then signal transmission and power supply functions are achieved, but cable occupancy space increases and maintenance complexity increases
Solution Approach 1:
The patent combines the cold plate body (for heat dissipation) with the flexible printed circuit (for signal transmission and power supply) into an integrated cold plate assembly. This merging eliminates the need for separate cables, reducing cable occupancy and simplifying maintenance while achieving heat dissipation, signal transmission, and power supply functions simultaneously
Solution Approach 2:
The cold plate assembly is designed to perform multiple functions: the cold plate body provides heat dissipation through cooling liquid flow channels, while the integrated flexible printed circuit provides signal transmission and power supply. This multi-functional design reduces the number of separate components and cables needed in the electronic device
2Volume of moving object
If cables are used for connecting modules or boards, then signal transmission and power supply are implemented, but the size of the electronic device increases
Solution Approach 1:
By merging the cold plate body and flexible printed circuit into a single integrated assembly, the patent reduces the overall volume required for cable connections. The integrated design eliminates redundant space occupied by separate cables and their connectors, thereby reducing the electronic device size while improving integration
3Device complexity
If separate cables are used for heat dissipation, signal transmission, and power supply, then each function is independently achieved, but the overall system complexity and space consumption increase
Solution Approach 1:
The cold plate assembly is designed as a multi-functional component where the cold plate body handles heat dissipation and the integrated flexible printed circuit handles signal transmission and power supply. This universal design allows a single assembly to replace multiple separate systems, reducing space consumption and simplifying the overall system
