Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measurements are performed for each energy range, then measurement precision for each energy range is ensured, but measurement time increases significantly
Solution Approach 1:
The detector is divided into multiple unit regions, each independently detecting a specific energy range. This segmentation allows simultaneous measurement of multiple energy ranges without requiring sequential measurements, thereby reducing total measurement time while maintaining precision for each energy range through dedicated detection regions.
Solution Approach 2:
The patent transitions from sequential energy range measurement to parallel measurement by utilizing spatial dimensionality of the detector. Different energy ranges are assigned to different spatial regions (unit regions) of the detector, enabling simultaneous detection across multiple energy ranges without temporal sequencing.
2Productivity
If different energy ranges are set in multiple unit regions, then simultaneous measurement of multiple energy ranges is enabled, but device complexity increases
Solution Approach 1:
The control apparatus is designed to perform multiple functions through a unified system. The setting section, data management section, and outputting section work together to simultaneously manage multiple energy range detections, making the control apparatus multi-functional rather than requiring separate devices for each energy range measurement.
Solution Approach 2:
Multiple detection functions for different energy ranges are merged into a single detector system with multiple unit regions. Instead of using separate detectors or measurement systems for each energy range, the patent combines all detection capabilities into one integrated apparatus, reducing overall system complexity despite the increased functionality.
3Adaptability or versatility
If zero point shift and gain change are performed for each unit region, then energy range setting flexibility is improved, but signal processing complexity increases
Solution Approach 1:
Each unit region of the detector is assigned specific zero point shift and gain change parameters tailored to its designated energy range. This local optimization allows each region to be precisely tuned for its specific energy detection task, improving energy range setting flexibility while the centralized control apparatus manages the complexity of individual region adjustments.
