Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tracking systems are used to determine particle paths and measure energy, then particle tracking capability is achieved, but the system requires high voltage supply and periodic maintenance
Solution Approach 1:
The patent replaces conventional electronic detection systems requiring high voltage with a mechanical/optical fiber-based detection system. The scintillating fibers convert particle energy deposits into light signals that are detected without requiring high voltage supplies, thereby eliminating the complex power requirements while maintaining tracking capability.
Solution Approach 2:
The patent utilizes scintillating fibers that emit light (color change) when high energy particles pass through them. This optical signal generation allows for particle detection and tracking without requiring high voltage supplies, replacing complex electronic systems with simpler optical detection.
2Measurement precision
If conventional tracking systems are used to measure particle energy, then energy measurement is achieved, but the system fails to separate the wide range of high energy particles' kinetic energy spectrum
Solution Approach 1:
The patent divides the detection system into multiple layers of scintillating fibers arranged in different orientations. Each layer segment captures spatial information at different depths, allowing the reconstruction of complete particle trajectories and energy deposition profiles. This segmentation enables separation of the kinetic energy spectrum by analyzing energy deposits in each fiber layer independently.
Solution Approach 2:
The patent employs three-dimensional positioning by arranging scintillating fibers in multiple layers with different orientations (e.g., horizontal and vertical). This multi-dimensional spatial resolution allows for precise tracking of particle paths through the detector volume and enables differentiation of particles with varying kinetic energies based on their interaction patterns across multiple spatial dimensions.
3Measurement precision
If detector panels with fibres are used for tracking, then tracking accuracy is improved, but material scattering increases
Solution Approach 1:
The patent uses scintillating fibers with relatively low density and atomic number compared to conventional solid scintillator blocks. The fibrous structure with inter-fiber spaces reduces the overall material density, thereby minimizing scattering effects on high energy particles while maintaining sufficient detection capability through the distributed fiber network.
Solution Approach 2:
The detector employs composite construction with scintillating fibers embedded in a support matrix or mounted on panels. This composite structure allows optimization of the scintillating material properties for detection while using low-density support materials that minimize scattering, achieving a balance between tracking accuracy and reduced material interference.
