Engineering Contradiction Analysis
1Reliability
If existing calibration methods are used, then calibration verification can be performed, but the process is complex and time-consuming
Solution Approach 1:
The measurement object combines multiple calibration functions into a single integrated structure. The plate includes both a first region for X-ray fluorescence calibration and a second region for optical alignment calibration, allowing simultaneous verification of both calibration systems in one measurement process, thereby reducing overall verification time and complexity
Solution Approach 2:
The measurement object serves multiple calibration purposes simultaneously. It acts as both an X-ray fluorescence calibration standard and an optical alignment reference, enabling the calibration verification process to cover multiple aspects (X-ray beam alignment, optical system alignment, and fluorescence intensity) in a single operation
2Reliability
If existing calibration methods are used, then calibration verification can be performed, but the process is complex
Solution Approach 1:
The measurement object is divided into distinct functional regions: a first region with specific material composition for X-ray fluorescence calibration and a second region with different material properties for optical alignment. This segmentation allows each region to be optimized for its specific calibration function while maintaining a simple, unified overall structure that ease of operation
3Measurement precision
If calibration is performed after transport or temperature changes, then accuracy is maintained, but readjustment is required
Solution Approach 1:
The measurement object enables self-verification of calibration status. By measuring the fluorescence intensity from the first region and optical characteristics from the second region, the system can automatically determine whether readjustment is needed after transport or temperature changes, eliminating the need for manual inspection and simplifying the operation
