Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single source and single detector are used in conventional industrial CT scanning, then the device complexity is low, but the scanning time is long and the productivity is reduced
Solution Approach 1:
The patent combines three X-ray sources and three detectors into a single CT scanning system, allowing simultaneous data acquisition from multiple angles. This merging of multiple detection channels enables the system to complete a full 360-degree scan in one rotation rather than requiring multiple sequential scans, thereby tripling the scanning speed while maintaining manageable system complexity through coordinated control of the multiple components
Solution Approach 2:
The patent divides the detection task into three simultaneous channels, each consisting of an X-ray source and detector pair. Each channel independently captures projection data from a specific angular sector, and the results are integrated to form the complete tomographic image. This segmentation allows parallel processing of multiple angular views, significantly reducing total scanning time while keeping each individual detection channel relatively simple
2Measurement precision
If more projection data is collected to improve image quality, then the signal-to-noise ratio decreases and image quality improves, but the scanning time and radiation time are increased
Solution Approach 1:
The patent implements continuous data acquisition across three simultaneous detection channels throughout the entire 360-degree rotation, ensuring that projection data is collected continuously without interruption. This continuous multi-channel acquisition captures sufficient angular information for high-quality reconstruction in a single rotation cycle, eliminating the need for repeated scanning while maintaining excellent signal-to-noise ratio and image quality
Solution Approach 2:
The patent transitions from sequential angular sampling in a single detection channel to simultaneous multi-dimensional data acquisition across three spatially distributed channels. This dimensional expansion in the detection architecture allows the system to gather equivalent or superior projection data coverage in one rotation rather than requiring multiple sequential passes, thereby reducing scanning time while preserving or enhancing image quality
3Loss of information
If the specimen rotates 360 degrees for complete scanning, then comprehensive projection data is obtained for high-quality reconstruction, but the scanning time is extended
Solution Approach 1:
The patent merges three detection channels positioned at different angular locations to simultaneously capture projection data covering the entire 360-degree range. By combining the angular coverage of multiple channels, the system achieves complete data acquisition for full tomographic reconstruction in a single rotation, eliminating the need for multiple sequential scans and thereby reducing scanning time while maintaining data completeness

Function Achieved in This Case
The system significantly reduces scanning time by two-thirds while ensuring high-quality imaging, improving detection efficiency and enabling accurate measurement and analysis of high-density materials, thus expanding the application range of industrial CT systems.
Implementation Method 1
X-rays with certain energy and intensity that are emitted by a ray source can penetrate through the specimen detected to perform tomography on the specimen
Implementation Method 2
The detector converts projection data of section slices of the specimen at different angles, which is collected in a rotating and scanning process of the specimen, into digital information
