Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical connectors are used in liquid-cooled environments without optimized heat dissipation structures, then the connector can be applied in new environments, but the heat dissipation effect is insufficient
Solution Approach 1:
The insulating body is divided into multiple wall portions, with each wall portion containing independent cooling liquid circulation grooves. This segmentation allows the cooling liquid to flow through multiple separate channels, increasing the heat dissipation surface area and improving overall heat dissipation efficiency in liquid-cooled environments.
Solution Approach 2:
The patent introduces cooling liquid circulation grooves that extend in the thickness direction of the insulating body, creating a three-dimensional cooling pathway. This dimensional extension allows the cooling liquid to access and cool internal structures that are not reachable by conventional surface-level cooling methods.
2Ease of manufacture
If conventional electrical connector structures are used, then manufacturing is simple, but heat dissipation performance is insufficient for liquid-cooled environments
Solution Approach 1:
The insulating body simultaneously serves as both the structural support for the electrical connector and as a heat dissipation component through its integrated cooling liquid circulation grooves. This multi-functionality allows the same structure to provide both mechanical support and thermal management, improving reliability without adding separate cooling components.
Solution Approach 2:
The cooling liquid circulation grooves are merged directly into the insulating body structure, combining the insulation function and heat dissipation function into a single integrated component. This merging eliminates the need for separate cooling channels or additional parts, maintaining ease of manufacture while improving heat dissipation performance.
