Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If visual observation method is used to detect residual air bubbles, then the detection process is simple, but the detection time is long and detection precision is low
Solution Approach 1:
The patent replaces the mechanical visual observation method with a pressure-based detection system. A pressure sensor measures pressure changes in the coolant, and a controller analyzes these changes to detect air bubbles. This substitution of mechanical observation with a sensor-based system resolves the contradiction by providing rapid, automated detection without increasing system complexity significantly.
Solution Approach 2:
The detection system enables the liquid-cooling system to self-diagnose the presence of air bubbles through pressure monitoring. The controller automatically analyzes pressure data and determines whether air bubbles are present, eliminating the need for manual visual inspection and reducing detection time while maintaining simplicity.
2Device complexity
If visual observation method is used to detect residual air bubbles, then the detection system is simple, but the measurement precision is insufficient
Solution Approach 1:
The patent replaces imprecise visual observation with a pressure sensor-based measurement system. The pressure sensor detects subtle pressure changes caused by air bubbles, and the controller analyzes these changes to determine bubble presence with high precision. This mechanical-to-sensor substitution directly addresses the measurement precision issue while keeping the system relatively simple.
Solution Approach 2:
The detection system uses feedback from pressure sensor measurements to accurately determine the presence of air bubbles. The controller continuously monitors pressure changes and uses this feedback to make precise detection decisions, significantly improving measurement precision over visual observation while maintaining acceptable system complexity.
3Device complexity
If manual coolant addition is used to remove residual air bubbles, then the process is simple, but the productivity is low
Solution Approach 1:
The patent implements a feedback-based coolant addition control system. The pressure sensor continuously monitors for air bubbles, and the controller automatically controls coolant addition based on detection results. This feedback mechanism dramatically improves productivity by eliminating the need for prolonged manual coolant addition, while the automated control keeps the process relatively simple.
Solution Approach 2:
The system enables self-service air bubble removal through automated coolant addition control. The controller automatically manages the coolant addition process based on pressure sensor feedback, eliminating the need for continuous manual intervention and significantly improving productivity while maintaining process simplicity.
4Measurement precision
If automated pressure-based detection system is implemented, then the detection precision is improved, but the device complexity increases
Solution Approach 1:
The patent implements a pressure sensor-based detection system that replaces complex visual observation procedures with a simple sensor and controller combination. The pressure sensor measures pressure changes, and the controller analyzes these changes to detect air bubbles with high precision. This approach improves measurement precision while keeping device complexity relatively low by using straightforward pressure measurement technology.
Solution Approach 2:
The detection system provides self-service functionality through automated pressure analysis. The controller automatically processes pressure sensor data and determines air bubble presence without requiring complex external analysis equipment or procedures, thereby improving precision while minimizing the increase in device complexity.
5Productivity
If automated pressure-based detection system is implemented, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The patent implements a feedback-based automated detection and control system. The pressure sensor provides real-time feedback on air bubble presence, and the controller automatically adjusts coolant addition based on this feedback. This feedback mechanism dramatically improves productivity by enabling rapid, accurate detection and response, while the automated control logic keeps the overall system complexity manageable.
Solution Approach 2:
The system enables self-service air bubble removal through automated pressure-based detection and control. The controller automatically manages the entire process from detection to coolant addition adjustment, significantly improving productivity while maintaining relatively simple system architecture through self-service operation.
