Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple layers of superconducting strips are stacked to increase detection probability, then the detection efficiency of X-ray photons is improved, but the device complexity increases
Solution Approach 1:
The patent applies dimensional change by arranging superconducting strips in multiple detection regions with different orientation directions (e.g., first direction D1, second direction D2, third direction D3) rather than simply stacking identical layers. This multi-directional arrangement in three-dimensional space enables comprehensive X-ray detection from various angles, improving detection efficiency while avoiding the redundancy of identical stacked layers and thereby controlling device complexity.
Solution Approach 2:
The detection device is segmented into multiple detection regions, each containing superconducting strips arranged in specific directions. This segmentation allows each region to specialize in detecting X-rays from particular orientations, collectively achieving high detection efficiency without requiring a monolithic complex structure. The segmented approach enables modular design and simplifies the overall system architecture.
2Reliability
If multiple layers of superconducting strips are used to prevent detection failures, then the reliability of particle detection is improved, but the manufacturing complexity increases
Solution Approach 1:
Instead of manufacturing multiple identical stacked layers, the patent introduces directional diversity by arranging superconducting strips in different orientations across multiple detection regions. This dimensional approach ensures that X-rays incident from any direction will be detected by at least one appropriately oriented strip, preventing detection failures while simplifying manufacturing by avoiding redundant identical layers.
Solution Approach 2:
Each detection region is assigned a specific local quality characteristic - superconducting strips in each region are oriented in a particular direction optimized for detecting X-rays from that direction. This local specialization ensures comprehensive coverage without requiring uniform complex structures throughout, thereby improving detection reliability while facilitating easier manufacturing through localized optimization.
3Reliability
If superconducting strips are arranged in different directions in multiple detection regions, then the detection coverage of X-ray photons is improved, but the device structure becomes more complex
Solution Approach 1:
The patent resolves the contradiction by utilizing directional dimensionality - arranging superconducting strips in different spatial orientations (first direction D1, second direction D2, third direction D3) across multiple detection regions. This approach expands detection coverage to encompass X-rays incident from various angles without requiring excessive structural complexity, as each directional arrangement serves a specific detection purpose.
Solution Approach 2:
The device structure is segmented into distinct detection regions, each with a simplified internal structure containing superconducting strips oriented in a specific direction. This segmentation reduces the complexity of individual regions while the collective arrangement of multiple segmented regions achieves comprehensive detection coverage, effectively distributing the structural complexity across modular units.

Function Achieved in This Case
This configuration enhances the detection efficiency of X-ray photons by preventing detection failures and enabling the generation of detailed X-ray projection images with reduced generation time, applicable to various particles beyond X-rays.
Implementation Method 1
a bias current is supplied to the superconducting strip in a superconducting state. When the X-ray photon collides with the superconducting strip in this state, a temporal transition to a non-superconducting state arises in the vicinity of a region with which the X-ray photon collides, and thus a pulsed electrical signal is generated.
