Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual determination of scanner position and alignment is used, then the process requires human expertise and manual calculations, but it is costly, time-consuming, and error-prone
Solution Approach 1:
The system performs self-calibration by automatically detecting reference points on the reference body and computing scanner position and alignment parameters through software calculations, eliminating the need for manual gauging and alignment procedures
Solution Approach 2:
Manual mechanical gauging and alignment procedures are replaced by an automated optical scanning system that detects reference points and computes positioning parameters through software, substituting human-operated mechanical methods with automated sensor-based measurement
2Adaptability or versatility
If multiple scanners and reference bodies are used to improve measurement coverage, then the accuracy and completeness of stockpile measurement is enhanced, but the system complexity and cost increase
Solution Approach 1:
The reference body serves multiple functions: it provides reference points for scanner calibration, enables determination of scanner position and alignment, and can be used with multiple different scanners. The system is designed to accommodate varying numbers of scanners and reference bodies based on specific measurement requirements
Solution Approach 2:
The system configuration is flexible and adaptable - the number and positioning of scanners and reference bodies can be dynamically adjusted based on the specific measurement task, stockpile geometry, and visibility requirements, allowing optimization between measurement quality and system complexity

AI summary
In a method for measuring a stockpile, a scanner detects a reference point of a reference body. A scanner position and a scanner alignment for the scanner is ascertained using the detected reference point. Scan data of the stockpile is detected by the scanner and a position and volume of the stockpile is ascertained using the scan data.
