Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional radiation detectors are used, then radiation detection capability is achieved, but the device becomes bulky and heavy
Solution Approach 1:
The patent changes the material parameter from conventional detector materials to cadmium zinc telluride (CZT) crystal, which has superior radiation detection properties and higher density. This material substitution enables compact detector design while maintaining or improving detection capability. The simulation-optimization approach further refines crystal parameters (size, shape, orientation) to achieve optimal performance in minimal volume.
Solution Approach 2:
The patent performs Monte-Carlo simulation and performance evaluation before actual detector manufacturing. By pre-evaluating multiple crystal configurations virtually, the optimal crystal parameters are determined in advance, avoiding trial-and-error manufacturing and reducing overall development time and resource consumption.
2Reliability
If conventional radiation detectors are used, then radiation detection function is provided, but the device size increases
Solution Approach 1:
The patent optimizes geometric parameters of the CZT crystal (dimensions, shape, orientation) through simulation to achieve the minimum volume required for effective radiation detection. The crystal configuration is specifically designed to maximize detection efficiency per unit volume, enabling compact detector design.
Solution Approach 2:
Virtual prototyping and performance evaluation are conducted before manufacturing to determine the minimum crystal volume and optimal configuration. This preliminary simulation phase identifies the smallest crystal dimensions that still achieve required detection performance, preventing over-engineering and excessive size.
3Volume of moving object
If CZT crystal size is reduced for compactness, then device volume decreases, but radiation response performance may deteriorate
Solution Approach 1:
The patent performs systematic Monte-Carlo simulation on CZT crystals of various sizes, shapes, and orientations before manufacturing. This preliminary virtual testing identifies the optimal crystal configuration that achieves the best balance between compact volume and radiation response performance, eliminating the need for trial-and-error physical prototyping.
Solution Approach 2:
The patent optimizes multiple crystal parameters simultaneously (dimensions, shape, orientation relative to radiation direction) to maximize detection efficiency per unit volume. By carefully adjusting these parameters, the crystal achieves high radiation response characteristics in a compact size, resolving the trade-off between volume and performance.
