Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a base plate is laminated onto the active matrix substrate by a gel sheet to reduce temperature distribution variations, then the structural support is improved, but the heat radiation efficiency deteriorates due to insufficient thermal conductivity of the gel sheet
Solution Approach 1:
The patent uses a composite structure combining a gel sheet for thermal conduction and a cooling panel with high thermal conductivity material for heat radiation. This composite approach allows the gel sheet to maintain temperature uniformity while the cooling panel efficiently radiates heat, resolving the contradiction between stability and energy loss.
Solution Approach 2:
The temperature control system is segmented into two functional parts: the gel sheet layer for distributing heat uniformly across the substrate, and the cooling panel for actively radiating heat away. This segmentation allows each component to optimize its specific function without compromising the other.
2Ease of manufacture
If the gel sheet is used to laminate the base plate onto the active matrix substrate, then the ease of manufacture is improved, but the thermal conductivity is insufficient to efficiently radiate heat
Solution Approach 1:
The patent combines the easy-to-manufacture gel sheet with a high-performance cooling panel made of thermally conductive material. This composite solution maintains the manufacturing simplicity of the gel sheet application while adding the heat dissipation reliability of the cooling panel through thermal conduction and radiation.
3Device complexity
If no active cooling mechanism is implemented, then the device complexity is reduced, but the temperature distribution uniformity deteriorates
Solution Approach 1:
The cooling panel utilizes passive thermal conduction and natural heat radiation principles, allowing the system to self-regulate temperature without requiring complex active cooling mechanisms. The high thermal conductivity material inherently conducts heat away from hot spots, maintaining temperature uniformity through self-service thermal management.
