Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the degree of integration of electronic components is increased, then the component area is reduced, but the heat flux density increases causing heat concentration
Solution Approach 1:
The heat dissipation layer is divided into multiple heat dissipation channels that segment the heat flow paths, allowing heat to be distributed and dissipated through multiple separate channels rather than concentrating in a single area, thus reducing heat flux density while maintaining compact component integration
Solution Approach 2:
A heat dissipation layer with thermally conductive metal material is introduced as an intermediary between the display panel and the environment, facilitating heat transfer from the high-density component area to the cooling medium flowing through the channels, thereby managing heat concentration without increasing component area
2Temperature
If heat dissipation channels are added to the display panel, then heat dissipation efficiency is improved, but the structural complexity increases
Solution Approach 1:
The heat dissipation layer is merged with the display panel structure, where the channels are integrated within the same structural framework rather than being separate additions, thus improving heat dissipation efficiency while minimizing increases in overall structural complexity
Solution Approach 2:
The heat dissipation layer serves multiple functions: it provides structural support, facilitates heat transfer, and contains the cooling medium channels, thereby achieving improved heat dissipation efficiency without proportionally increasing structural complexity through multi-functionality
