Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid cooling technology is adopted to cool the cable, then cooling effect is improved, but device complexity and cost increase
Solution Approach 1:
The patent integrates the cooling function directly into the cable structure by embedding cooling fins within the cable insulation layer, merging the current transmission function and heat dissipation function into a single integrated component. This eliminates the need for separate cooling pipelines, pumps, and heat dissipation devices, thereby reducing device complexity while maintaining effective cooling.
Solution Approach 2:
The patent extracts the essential cooling function from complex liquid cooling systems and implements it through simple cooling fins with fluid channels, removing unnecessary components such as pumps and complex pipeline systems while retaining the core heat dissipation capability.
2Device complexity
If air cooling technology is adopted to cool the cable, then device complexity is reduced, but cooling efficiency decreases and noise increases
Solution Approach 1:
The patent uses fluid (liquid or gas) flowing through channels within the cooling fins to transfer heat away from the conductor. This hydraulic cooling approach achieves superior cooling efficiency compared to air cooling while maintaining simple device structure, as the fluid circulation system is integrated within the cable itself without requiring external fans or complex airflow control mechanisms.
3Temperature
If cross-sectional area of the cable is increased to reduce heat, then heat dissipation is improved, but cable size and cost increase
Solution Approach 1:
The patent segments the cable structure into functional layers: conductor, insulation layer with embedded cooling fins, and outer protective layer. The cooling fins are further segmented into multiple channels that distribute coolant efficiently. This segmentation allows effective heat dissipation without requiring a larger overall cable cross-section, as the cooling function is distributed throughout the cable structure rather than requiring a single large conductor.
Solution Approach 2:
The patent adds a third dimension to heat dissipation by embedding cooling fins vertically within the insulation layer, creating a three-dimensional heat dissipation network. This allows heat to be conducted away from the conductor through the fins and dissipated via fluid flow, achieving effective cooling without increasing the cable's external cross-sectional dimensions.
