Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional calibration methods using total station and multiple measurement points are employed, then position detection accuracy is improved, but calibration time and complexity increase significantly
Solution Approach 1:
The patent extracts the essential calibration information by focusing on a single calibration point rather than requiring measurements at multiple points. The system calculates the blade tip position from the receiver position and compares it with the actual position at one calibration point, thereby obtaining the necessary calibration data without the need for comprehensive multi-point measurements, significantly reducing calibration time while maintaining accuracy
Solution Approach 2:
The patent uses the calculated blade tip position as a virtual copy or representation of the actual blade tip position. By comparing this calculated position (which is derived from receiver position and stored geometric data) with the actual measured position at a calibration point, the system can determine calibration corrections without requiring direct measurement of all blade tip positions, thereby simplifying the calibration process
2Measurement precision
If traditional calibration methods with multiple measurement points are used, then position detection accuracy is improved, but the calibration process becomes more complex
Solution Approach 1:
The patent extracts only the essential calibration information from a single calibration point, eliminating the need for complex multi-point measurement procedures. The system obtains calibration data by comparing the calculated and actual positions at one point, thereby simplifying the calibration process while maintaining the ability to correct position detection accuracy
Solution Approach 2:
The system performs self-calibration by automatically calculating the blade tip position from the receiver position and stored geometric data, then comparing it with the actual position at a calibration point. This self-comparison process generates the necessary calibration corrections without requiring complex external measurement equipment or multiple measurement points, thereby reducing calibration process complexity
3Measurement precision
If comprehensive calibration data collection is performed, then position detection accuracy is improved, but operational efficiency decreases
Solution Approach 1:
The patent extracts the minimum necessary calibration information from a single calibration point, avoiding the time-consuming comprehensive data collection at multiple points. This approach maintains position detection accuracy by obtaining essential calibration corrections while minimizing the time spent on calibration, thereby improving operational efficiency
Solution Approach 2:
The system performs preliminary calculations of the blade tip position based on stored geometric data and receiver position before actual operation. By having this calculation framework pre-established, the system can quickly perform calibration comparisons and generate corrections without requiring comprehensive real-time data collection, thereby improving operational efficiency while maintaining accuracy
