Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If heating units are arranged at different positions in a liquid cooling system, then the system can cool multiple heating units, but the cooling liquids flowing through the heating units have different flow rates and distinct flow resistances, resulting in inconsistent heat dissipation efficiency and poor temperature uniformity
Solution Approach 1:
The patent applies equipotentiality by designing the pipeline system so that all heating units have equal liquid passage length from the liquid inlet through the heating unit to the liquid outlet. This equalizes the flow resistance and flow rate across all heating units, ensuring uniform temperature distribution while maintaining the ability to cool multiple units simultaneously
Solution Approach 2:
The patent implements local quality by providing each heating unit with an identical cooling flow channel design and equal pipeline length. This ensures that each local position (heating unit) receives the same flow conditions, achieving consistent heat dissipation efficiency across all units while still allowing the system to adapt to multiple heating units
2Adaptability or versatility
If heating units have different flow rates due to varying pipeline paths, then the system can accommodate different positions, but heating units with high flow resistance have low flow rates and low heat dissipation efficiency, while those with low flow resistance have high flow rates and high heat dissipation efficiency
Solution Approach 1:
The patent equalizes the flow conditions for all heating units by designing identical liquid passage lengths and consistent pipeline configurations. This ensures that each heating unit operates at the same flow rate and heat dissipation efficiency, eliminating the productivity inconsistency caused by varying flow resistance while maintaining adaptability to different positions
3Ease of operation
If a liquid cooling system is designed with varying pipeline paths for different heating units, then the system can be flexible in layout, but the flow paths and heat dissipation efficiency of the heating units are significantly different, causing different service lives
Solution Approach 1:
The patent ensures service life consistency by designing all heating units with equal liquid passage length and identical cooling flow channel configurations. This equipotential design guarantees uniform flow rates and heat dissipation efficiency across all units, ensuring they operate under equivalent conditions and thus have consistent service lives, while the system remains flexible in layout
