Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detector module moves along a curve to capture partial images, then the imaging coverage and completeness are improved, but the complexity of motion control and image stitching increases
Solution Approach 1:
The detector module is divided into multiple spatially discontinuous active areas arranged in rows and columns. Each active area captures a specific portion of the scene, allowing the system to stitch multiple partial images into a complete image of the entire scene, thereby resolving the contradiction between imaging coverage and system complexity
Solution Approach 2:
The detector module is translated along a smooth curve through multiple movement rounds, with the velocity being a continuous function of time. This dynamic motion enables the detector to capture partial images at different positions along the curve, improving imaging coverage while maintaining controlled motion through continuous velocity functions
2Productivity
If spatially discontinuous active areas are used, then the detector can capture specific portions of the scene, but the complexity of coordinating multiple active areas increases
Solution Approach 1:
The detector module is divided into multiple spatially discontinuous active areas arranged in rows and columns. Each active area captures a specific portion of the scene, allowing the system to stitch multiple partial images into a complete image of the entire scene, thereby resolving the contradiction between imaging coverage and system complexity
Solution Approach 2:
Multiple partial images captured by different active areas are merged into a single complete image through stitching. The shield system also merges the functionality of blocking irrelevant radiation from reaching multiple active areas, improving capture efficiency while managing complexity through systematic organization
3Measurement precision
If the shield system blocks radiation not targeting the active areas, then the signal-to-noise ratio improves, but the complexity of shield translation and positioning increases
Solution Approach 1:
The shield system translates along with the detector module movement, dynamically adjusting its position to block radiation not targeting the active areas. The shield translation is coordinated with the detector's curved path motion, improving radiation targeting precision while managing positioning complexity through synchronized movement
Solution Approach 2:
The shield system acts as an intermediary between the radiation source and the active areas, blocking irrelevant radiation from reaching the detector. This mediator function improves the signal-to-noise ratio by systematically eliminating unwanted radiation signals
