Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signal-to-noise ratio-first nuclear pulse processing technologies are used, then energy resolution is improved, but pulse throughput deteriorates
Solution Approach 1:
The patent applies dynamics by making the pulse processing system adaptable to different counting rates. The system dynamically adjusts its processing mode: at low counting rates it uses signal-to-noise ratio-first processing for high resolution, while at high counting rates it switches to speed-first processing for high throughput. This dynamic adaptation resolves the contradiction between resolution and throughput by allowing the system to optimize for the current operational conditions.
Solution Approach 2:
The patent changes the processing parameters based on the counting rate conditions. It modifies the pulse processing algorithm parameters to prioritize either energy resolution or pulse throughput depending on the input signal characteristics. This parameter adjustment allows the system to maintain high performance across different operating conditions, effectively resolving the trade-off between resolution and throughput.
2Productivity
If speed-first energy spectrum measurement technologies are used, then pulse throughput is improved, but energy resolution deteriorates
Solution Approach 1:
The system dynamically switches between processing modes based on the counting rate. When high pulse throughput is required, it employs speed-first processing; when high resolution is needed, it switches to signal-to-noise ratio-first processing. This dynamic mode switching allows the system to overcome the fixed trade-off and achieve both high throughput and high resolution as needed.
Solution Approach 2:
The patent segments the pulse processing into different stages or modes: a first processing mode for signal-to-noise ratio optimization and a second processing mode for speed optimization. By dividing the processing into separate functional segments that can be selectively applied, the system can achieve high resolution when needed and high throughput when needed, without being constrained by a single processing approach.
3Device complexity
If traditional nuclear pulse processing is used, then processing simplicity is maintained, but performance under high pulse counting rates deteriorates
Solution Approach 1:
The patent divides the pulse processing into distinct segments: traditional simple processing for low counting rates and advanced multi-mode processing for high counting rates. This segmentation allows the system to maintain simplicity when high performance is not required, while enabling complex high-performance processing only when needed, thus balancing complexity and performance.
Solution Approach 2:
The system performs preliminary assessment of the counting rate conditions and pre-selects the appropriate processing mode before actual pulse processing begins. This preliminary action allows the system to prepare the optimal processing configuration in advance, ensuring high performance under high counting rates without adding excessive complexity to the real-time processing.
