Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If rays pass through conventional ray converter material, then ray energy is converted to visible light, but the emergent light has poor collimation and low intensity
Solution Approach 1:
The patent applies porous materials by constructing a ray converter with a mesoporous structure where conversion bodies are filled within pores of controlled size (2-10 μm). The porous structure restricts ray propagation paths and limits scattering, thereby improving both the collimation and intensity of emergent light while maintaining effective ray-to-light conversion
Solution Approach 2:
The patent segments the conversion medium into discrete conversion bodies positioned within individual pores of the mesoporous structure. This segmentation confines the interaction between rays and conversion material to specific localized regions, preventing lateral scattering and improving the directional properties (collimation) of the emergent light
2Measurement precision
If radiation dose is increased to improve detection signal, then detection accuracy improves, but safety hazards increase
Solution Approach 1:
The mesoporous structure with optimized pore size (2-10 μm) and porosity (60-80%) enhances the interaction between rays and conversion bodies, improving conversion efficiency. This allows achieving sufficient emergent light intensity for accurate detection at lower radiation doses, thereby improving measurement precision while reducing harmful radiation exposure
Solution Approach 2:
The patent changes physical parameters of the conversion structure, including pore size (2-10 μm), porosity (60-80%), and conversion body material properties, to optimize ray conversion efficiency. These parameter optimizations enable effective detection with reduced radiation doses by maximizing the utility of incident ray energy
