Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid insulator is used to cover the X-ray tube, then the insulating performance is improved, but gas may be generated due to thermal decomposition from discharging, which is difficult to detect
Solution Approach 1:
A gas sensor is introduced as an intermediary detection device within the container to detect gas generated by thermal decomposition of the liquid insulator. The gas sensor acts as a mediator between the insulator degradation process and the control system, enabling early detection of insulating performance deterioration through gas accumulation.
Solution Approach 2:
The system implements feedback control by continuously monitoring gas concentration in the liquid insulator via the gas sensor. When gas levels exceed predetermined thresholds, the system generates alerts or shuts down the X-ray generator, creating a closed-loop feedback mechanism that prevents further insulator degradation and maintains operational safety.
2Reliability
If the container is sealed to maintain insulator integrity, then operational stability is improved, but gas generated from insulator decomposition cannot be easily removed for detection
Solution Approach 1:
The gas sensor serves as an intermediary that enables indirect detection of insulator degradation through gas concentration measurement. This allows the sealed container to maintain its protective function while the gas sensor provides a detection mechanism without requiring container opening or gas removal operations.
Solution Approach 2:
The system replaces mechanical gas removal methods with an optical/electrical detection approach using the gas sensor. Instead of mechanically removing gas from the sealed container, the system uses sensor-based detection to monitor gas concentration, eliminating the need to break the seal for detection purposes.
3Device complexity
If no gas sensor is installed, then the device complexity is reduced, but the insulating performance degradation cannot be detected in time
Solution Approach 1:
The gas sensor is installed in advance within the container to detect gas accumulation before it reaches critical levels that would cause complete insulator failure. This preliminary detection capability allows the system to take preventive actions before severe damage occurs, maintaining high reliability without requiring complex monitoring systems.
Solution Approach 2:
The gas sensor represents a relatively simple, cost-effective addition to the system that provides continuous monitoring capability. Compared to complex comprehensive monitoring systems, the gas sensor offers an economical solution that effectively monitors insulator degradation through gas detection, balancing device complexity with monitoring reliability.
