Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If energy calibration is performed frequently based on operating time or use count, then energy position deviation is corrected, but unnecessary calibration operations occur and productivity is reduced
Solution Approach 1:
The system continuously monitors peak positions in the radiation spectrum and compares them against a database of known peak positions. When deviation exceeds a threshold, the system automatically triggers energy calibration. This feedback mechanism replaces fixed-schedule calibration with condition-based calibration, ensuring accuracy only when needed and eliminating unnecessary calibration operations that reduce productivity.
Solution Approach 2:
The radiation detector assembly performs self-diagnosis by automatically detecting energy position deviations through peak position analysis. The system independently determines when calibration is needed without external intervention or manual scheduling, enabling it to self-correct energy position accuracy issues while maintaining measurement efficiency.
2Productivity
If energy calibration frequency is reduced to avoid unnecessary operations, then productivity is improved, but energy position deviation may exceed tolerable range causing measurement errors
Solution Approach 1:
The system implements continuous monitoring of peak positions and automatic comparison with reference values. This real-time feedback ensures that energy position accuracy is maintained throughout continuous measurement operations, preventing deviations from exceeding tolerable ranges while allowing measurements to proceed without interruption for unnecessary calibrations.
Solution Approach 2:
The system performs preliminary detection of energy position deviations during normal measurement operations. By continuously analyzing peak positions and comparing them against the database of known peak positions, the system identifies deviations before they affect measurement accuracy, enabling proactive calibration only when necessary.
3Measurement precision
If manual evaluation of each measurement result is performed to check reliability, then measurement accuracy is ensured, but loss of time increases and productivity decreases
Solution Approach 1:
The radiation detector assembly automatically evaluates measurement reliability by continuously monitoring peak positions and comparing them against the database of known peak positions. The system independently determines whether energy calibration is needed and performs calibration automatically, eliminating the need for manual evaluation of each measurement result and preventing time loss while ensuring measurement reliability.
Solution Approach 2:
The system implements automatic feedback mechanisms that continuously assess measurement quality by analyzing peak position deviations. This automated quality control provides real-time assurance of measurement reliability without requiring manual intervention or time-consuming evaluation of individual results.
