Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple transmission images are taken with different viewing angles to achieve three-dimensional imaging, then three-dimensional structure information is improved, but radiation dose increases
Solution Approach 1:
The patent combines transmission imaging with scattered radiation detection into a single imaging system. The primary detector captures transmission images while the secondary detector captures scattered radiation images simultaneously, merging two imaging modalities to obtain three-dimensional information without requiring multiple separate exposures.
Solution Approach 2:
The imaging system performs multiple functions simultaneously: it captures transmission images for two-dimensional imaging and scattered radiation images for three-dimensional reconstruction, all within a single exposure event. This multi-functionality eliminates the need for multiple separate imaging procedures.
2Loss of information
If multiple transmission images are taken with different viewing angles to achieve three-dimensional imaging, then three-dimensional structure information is improved, but imaging time increases
Solution Approach 1:
The system merges transmission imaging and scattered radiation detection into a simultaneous process. Both types of images are captured during the same exposure event, eliminating the sequential time required for multiple separate imaging procedures.
Solution Approach 2:
The imaging system maintains continuous useful action by capturing both transmission and scattered radiation information simultaneously during a single exposure. This continuous data acquisition eliminates interruptions and repeated exposures required by traditional multi-angle imaging methods.
3Loss of information
If scattered x-ray radiation is detected to provide three-dimensional information, then internal structure information is improved, but device complexity increases
Solution Approach 1:
The detection system is segmented into two specialized detectors: a primary detector for transmission imaging and a secondary detector for scattered radiation detection. This segmentation allows each detector to be optimized for its specific function while working together to provide comprehensive three-dimensional information.
Solution Approach 2:
The patent introduces imaging optics as an intermediary component that guides scattered radiation from the sample to the secondary detector. This intermediary element enables effective scattered radiation detection without requiring direct line-of-sight detection, simplifying the overall system architecture.
4Productivity
If imaging optics are added to guide scattered radiation onto the secondary detector, then scattered radiation detection efficiency is improved, but device complexity increases
Solution Approach 1:
Imaging optics serve as an intermediary that efficiently channels scattered radiation onto the secondary detector. This intermediary component increases detection efficiency by focusing and guiding scattered photons, making the added complexity worthwhile for the significant improvement in detection capability.
