Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the analyzer is placed on the optical path for high-resolution measurement, then measurement precision is improved, but optical axis alignment becomes harder and measurement time increases
Solution Approach 1:
The detector surface is divided into a first detection area for receiving direct diffracted X-rays and a second detection area for receiving analyzer-reflected X-rays. This segmentation allows simultaneous detection from both optical paths without requiring sequential alignment operations, thereby maintaining high resolution while reducing measurement time.
Solution Approach 2:
The invention transitions from sequential optical path selection (one dimension) to simultaneous dual-path detection using a two-dimensional detector with spatially separated detection areas. This dimensional change enables parallel measurement of both direct and analyzer-reflected X-rays, eliminating the time-consuming sequential alignment process.
2Measurement precision
If the analyzer is attached and detached for high-resolution measurement, then measurement precision is improved, but device complexity and measurement cost increase
Solution Approach 1:
The invention merges the detection of direct X-rays and analyzer-reflected X-rays into a single detector assembly with two spatially separated detection areas. This integration eliminates the need for separate attachment and detachment operations, reducing device complexity while maintaining the capability for high-resolution measurement.
Solution Approach 2:
The detector is designed with multi-functionality, serving both as a direct detection device and an analyzer-based detection device through its two detection areas. This universal detector design eliminates the need for separate analyzer attachment/detachment mechanisms, simplifying the overall system while enabling high-resolution measurements.
3Measurement precision
If optical axis alignment is performed at each measurement, then measurement precision is maintained, but productivity decreases
Solution Approach 1:
The detector is pre-configured with two spatially separated detection areas positioned to receive X-rays from two different optical paths. This preliminary geometric arrangement eliminates the need for real-time optical axis alignment during measurements, maintaining alignment accuracy while significantly improving measurement efficiency and productivity.
