Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a heat conductive sheet is used for heat dissipation in devices with movable components, then heat dissipation efficiency is improved, but the heat conductive sheet suffers wear when members are displaced
Solution Approach 1:
The heat conductive sheet is divided into two functional layers: a heat conductive layer for thermal transfer and a protective layer for mechanical protection. This segmentation allows each layer to specialize in its primary function while working together as an integrated component.
Solution Approach 2:
The heat conductive sheet is constructed as a composite structure combining a heat conductive layer (made of heat conductive material) and a protective layer (made of wear-resistant material). This composite design enables simultaneous achievement of high heat dissipation efficiency and wear resistance.
2Adaptability or versatility
If members are made displaceable for device functionality, then adaptability is improved, but wear of the heat conductive sheet increases
Solution Approach 1:
The protective layer acts as an intermediary between the heat conductive layer and the moving members. It absorbs the mechanical wear and friction during displacement while allowing the heat conductive layer to maintain its thermal transfer function without direct contact with moving parts.
Solution Approach 2:
The protective layer is applied in advance to the heat conductive sheet before the device begins operation. This preliminary protective measure ensures that the heat conductive sheet is already protected against wear from the first moment of member displacement, extending its service life.
