Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If air cooling is used, then no separate cooling medium is required, but cooling efficiency is low
Solution Approach 1:
The patent introduces an oil-based coolant as an intermediary substance between the heat source and the cooling system. This coolant directly contacts the heat-generating component, enabling efficient heat transfer while maintaining system simplicity. The coolant absorbs heat through direct contact and transports it away, resolving the contradiction between simple implementation and cooling efficiency.
2Productivity
If water cooling is used, then cooling efficiency is high, but direct contact with heat generation source is difficult
Solution Approach 1:
The patent changes the physical and chemical parameters of the cooling medium by using oil-based coolant instead of water. The oil-based coolant has appropriate viscosity, thermal conductivity, and chemical stability that enable it to directly contact heat-generating components while maintaining high cooling efficiency. This parameter change allows direct contact cooling to be both feasible and effective.
3Productivity
If coolant with high thermal conductivity is used, then cooling efficiency improves, but insulation performance may deteriorate
Solution Approach 1:
The patent applies local quality by having the coolant perform different functions in different locations. Where the coolant contacts the heat-generating component, it provides high thermal conductivity for efficient heat absorption. In other regions, particularly where electrical components are present, the oil-based coolant provides electrical insulation. This spatial differentiation of functional properties resolves the contradiction between cooling efficiency and insulation performance.
