Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat sink is added between the backplanes to improve heat radiation, then heat dissipation effectiveness is improved, but device complexity increases
Solution Approach 1:
The first heat sink is nested between the first and second backplanes, utilizing the existing spatial arrangement of display modules. The heat sink is positioned within the sandwich structure formed by the backplanes, allowing heat dissipation without requiring additional external space or complex mounting arrangements.
Solution Approach 2:
The heat sink is divided into multiple elongated members arranged in parallel, with grooves provided between adjacent elongated members. This segmentation increases the surface area for heat radiation and creates channels for air flow, improving heat dissipation effectiveness while maintaining a compact structure.
2Temperature
If multiple elongated members with grooves are used to enhance heat conduction, then heat dissipation effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
Grooves are provided between adjacent elongated members at specific locations where heat dissipation is most needed. The grooves create localized air channels that enhance convective heat transfer from the backplanes to the surrounding environment, improving heat conduction effectiveness without requiring complex manufacturing processes for the entire heat sink structure.
