Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional XRD detection systems use single beam detection, then device complexity is low, but collection efficiency for scattered beam signals is low
Solution Approach 1:
The detection system divides detectors into multiple groups (first detectors and second detectors) with different functions. First detectors receive transmitted beam signals while second detectors receive scattered beam signals. This segmentation allows each detector group to specialize in collecting specific signal types, improving overall collection efficiency without requiring a single complex detector to handle all signals
Solution Approach 2:
The patent extends detection from a single detection plane to multiple detection planes arranged along the transmission direction. By placing first and second detectors at different positions and orientations in three-dimensional space, the system captures scattered beam signals from multiple spatial dimensions, significantly increasing photon collection efficiency
2Productivity
If conventional systems use single beam signals, then detection system is simple, but detection efficiency is low
Solution Approach 1:
The system merges multiple columns of beam signals (at least two columns) into a single detection system. By combining multiple beam columns that pass through different regions of the object, the system increases the total number of photons collected per unit time, thereby improving detection efficiency and throughput
Solution Approach 2:
The system maintains continuous detection by having multiple beam columns operating simultaneously rather than sequentially. Multiple first detectors and second detectors continuously receive transmitted and scattered signals from multiple beam columns, eliminating idle time and maintaining constant detection productivity
