Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional visual observation method is used to detect residual air bubbles, then the system structure remains simple, but the detection time is excessively long and detection precision is insufficient
Solution Approach 1:
The patent replaces the conventional visual observation method (mechanical/manual detection) with a pressure-based detection system. The pressurizing device applies pressure to the coolant and measures transient pressure responses to detect air bubbles, substituting manual visual inspection with an automated physical measurement system that provides both higher precision and faster results.
Solution Approach 2:
The patent introduces pressure as an intermediary parameter to detect the presence of air bubbles. Instead of directly observing air bubbles visually, the system uses pressure changes in the coolant as a mediator to indirectly detect and locate air bubbles, enabling precise and rapid detection without direct visual contact.
2Ease of operation
If manual visual observation is used to determine air bubble removal, then the detection method remains simple, but the operational complexity increases due to prolonged coolant addition and inability to observe cold plate interior
Solution Approach 1:
The detection system enables the liquid-cooling system to self-diagnose the presence of air bubbles. The pressurizing device and pressure sensor allow the system to automatically detect and locate air bubbles without requiring manual observation or prolonged coolant addition, making the operation simpler and more efficient.
3Reliability
If prolonged coolant addition is performed to ensure air bubble removal, then cooling performance may be improved, but the time consumption and operational trouble increase significantly
Solution Approach 1:
The patent implements a feedback mechanism where the pressure sensor continuously monitors pressure changes in the coolant system. When air bubbles are detected through characteristic transient pressure responses, the system provides immediate feedback, allowing operators to stop coolant addition at the optimal point, ensuring reliable cooling performance while minimizing time consumption and operational complexity.
