Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CT technique is used to obtain 3D information, then imaging accuracy is improved, but equipment complexity and cost increase
Solution Approach 1:
The patent divides the imaging system into separate functional components: a radiation source, collimators for beam shaping, and detector arrays for signal reception. This segmentation allows each component to be optimized independently while achieving 3D imaging capability without requiring a complete CT scanner system.
Solution Approach 2:
The patent transitions from conventional 2D projection imaging to 3D tomographic imaging by introducing detector arrays that capture signals from multiple angles. The collimators create divergent beams that pass through the object at different orientations, enabling reconstruction of three-dimensional structures from two-dimensional detector readings.
2Device complexity
If single-viewing angle scan is used, then device simplicity is maintained, but image overlap occurs making inspection difficult
Solution Approach 1:
The patent introduces angular diversity by arranging collimators and detector arrays to receive radiation beams from multiple viewing angles. This dimensional addition of angular information allows the system to distinguish between overlapping objects at different depths, eliminating the superposition problem of single-angle imaging while maintaining relative structural simplicity.
Solution Approach 2:
The collimators are arranged asymmetrically relative to the radiation source, creating divergent beam paths that provide multiple viewing angles. This asymmetric arrangement enables the detection of objects at different depths and orientations, preventing image overlap while keeping the overall device structure simple and compact.
3Measurement precision
If CT technique is used for large-sized objects, then imaging capability is improved, but inspection speed decreases
Solution Approach 1:
The collimators are pre-positioned to create divergent beams that simultaneously illuminate multiple regions of large-sized objects. The detector arrays are pre-configured to capture signals from these pre-diverged beams, enabling parallel acquisition of data from different spatial locations and improving inspection speed without sacrificing imaging quality.
Solution Approach 2:
By introducing angular diversity through strategically positioned collimators and detector arrays, the system achieves 3D imaging capability that allows rapid scanning of large objects. The multi-angle detection geometry enables faster data acquisition compared to conventional single-angle methods, improving productivity while maintaining comprehensive imaging coverage.
