Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the equipment is opened for maintenance, then maintenance can be performed, but atmospheric moisture mixes into the sealed tank and reduces evaporation and condensation efficiency
Solution Approach 1:
The system performs preliminary separation of water from the heat dissipation medium using a flow guiding structure before the medium re-enters the sealed tank. This preliminary action removes moisture contamination that would otherwise mix with the medium during maintenance, preserving evaporation and condensation efficiency without preventing maintenance access.
2Use of energy by moving object
If water content in the heat dissipation medium is high, then the medium can absorb more heat, but equipment damage occurs
Solution Approach 1:
The flow guiding structure extracts and removes water from the heat dissipation medium through gravitational separation. By continuously removing water despite heat absorption, the system maintains appropriate water content levels that prevent equipment damage while preserving heat absorption capability.
Solution Approach 2:
The flow guiding structure acts as an intermediary between the heat dissipation medium and the equipment. It mediates the interaction by separating water before the medium contacts equipment surfaces, preventing direct damage from high water content while allowing heat absorption to proceed.
3Speed
If a flow guiding structure is added to separate water, then separation speed increases, but device complexity increases
Solution Approach 1:
The flow guiding structure segments the heat dissipation medium flow path into distinct regions: an upper flow guiding unit for initial water separation and a lower flow guiding unit for final water discharge. This segmentation achieves rapid separation through multiple stages without requiring complex mechanisms, maintaining structural simplicity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system accelerates the separation of heat dissipation medium and water, reducing the time to a stable state and minimizing equipment damage by maintaining efficient evaporation and condensation.
Implementation Method 1
the heat dissipation medium absorbs thermal energy in the first accommodating space and then gasifies
Implementation Method 2
the gasified heat dissipation medium is condensed and liquefied via heat exchange in the condensing unit
Implementation Method 3
the liquefied heat dissipation medium flows on the flow guiding structure to separate water contained in the liquefied heat dissipation medium
