Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of measurement conditions is performed to improve detection accuracy, then detection precision is improved, but measurement time increases and operation becomes complex
Solution Approach 1:
The system automatically adjusts measurement conditions by performing test measurements and evaluating detection accuracy without operator intervention. The controller autonomously determines optimal settings based on measured data, eliminating the need for manual adjustment while maintaining high detection accuracy.
Solution Approach 2:
The system performs test measurements with different measurement conditions and evaluates detection accuracy for each condition. Based on the evaluation results, the controller automatically selects and applies the optimal measurement conditions, creating a feedback loop that continuously optimizes detection accuracy while minimizing measurement time.
2Measurement precision
If manual adjustment of measurement conditions is performed to improve detection accuracy, then detection precision is improved, but device complexity increases
Solution Approach 1:
The controller automatically performs test measurements and determines optimal measurement conditions without requiring operator expertise or manual intervention. This automation eliminates the complexity of manual adjustment procedures while maintaining high detection accuracy through systematic evaluation of different conditions.
Solution Approach 2:
The system replaces manual operator judgment and adjustment with automated electronic control and algorithmic optimization. The controller uses computational methods to evaluate detection accuracy and determine optimal conditions, substituting human expertise with automated intelligence to reduce operational complexity.
3Measurement precision
If multiple test measurements are performed to determine optimal conditions, then detection accuracy is improved, but productivity decreases
Solution Approach 1:
The system performs a limited number of test measurements with different measurement conditions to determine optimal settings, rather than exhaustively testing all possible conditions. This partial action approach achieves sufficient detection accuracy while minimizing the time and resources required for optimization.
Solution Approach 2:
The system systematically varies measurement conditions (such as laser power, ion beam current, and detection parameters) during test measurements to identify optimal settings. By changing key parameters in a structured manner, the system efficiently determines optimal conditions without requiring exhaustive testing of all possible parameter combinations.
