Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If connection pipes are disposed between cold plates, then heat dissipation efficiency is maintained, but fragmented spaces are created reducing space utilization
Solution Approach 1:
The connection pipes are repositioned from a horizontal arrangement between cold plates to a vertical arrangement extending upward from the cold plate assembly. This dimensional change eliminates fragmented spaces and improves space utilization while maintaining heat dissipation efficiency through the vertical connection path.
2Volume of stationary object
If condenser size is reduced to accommodate connection pipes, then space utilization improves, but heat dissipation efficiency decreases
Solution Approach 1:
The connection pipes extend vertically from the cold plates rather than horizontally between them, allowing the condenser to maintain its full size for optimal heat dissipation while the vertical pipe arrangement improves space utilization by eliminating fragmented spaces.
3Loss of energy
If connection pipes are placed externally between cold plates, then heat dissipation is maintained, but device complexity increases due to fragmented spaces
Solution Approach 1:
The connection pipes are integrated with the cold plate structure through vertical extension, merging previously separate components into a unified assembly. This reduces structural complexity by eliminating fragmented spaces and simplifying the overall device architecture while maintaining heat dissipation efficiency.
