Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of the scintillation crystal is reduced to miniaturize the detector, then the device size decreases and mobility improves, but the sensitivity and detection effectiveness deteriorate
Solution Approach 1:
The invention divides a single large detector into multiple smaller detection units, each with its own scintillation crystal and processing module. These units are distributed spatially and connected via network interfaces, allowing the system to maintain miniaturization while achieving collective detection sensitivity equivalent to or exceeding a single large detector.
Solution Approach 2:
Multiple small detection units are merged into a coordinated networked system that shares data and processing resources. The central processing module aggregates data from all detection units, enabling the system to achieve high sensitivity through combined statistical analysis while each individual unit remains miniaturized.
2Volume of moving object
If the scintillation crystal is made smaller, then device miniaturization is achieved, but the ability to distinguish background radiation from actual events deteriorates
Solution Approach 1:
The detection system is segmented into multiple independent units, each capable of detecting radiation events. By distributing detection across multiple small crystals rather than relying on a single small crystal, the system accumulates sufficient statistical data to distinguish signal from background radiation.
Solution Approach 2:
The system implements feedback through networked communication between detection units and centralized processing. Data from multiple units provides feedback that enhances statistical analysis, allowing the system to differentiate between background radiation and actual events with higher precision than a single small detector could achieve.
3Device complexity
If a single detector is used, then device simplicity is maintained, but the capability to determine directionality and triangulate radiation sources deteriorates
Solution Approach 1:
The detection function is segmented across multiple spatially distributed units, each equipped with positioning capabilities. This segmentation enables the system to determine directionality and triangulate radiation sources by comparing signals from different locations, transforming a complex functional requirement into a distributed capability.
Solution Approach 2:
The system transitions from a single-point detection model to a distributed spatial array, adding dimensional information to the detection process. By incorporating positioning modules and distributing detectors in three-dimensional space, the system gains the ability to determine directionality and locate radiation sources without significantly increasing operational complexity.
