Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional nuclear spectrometers use a single analog signal processing pathway, then the system is simpler and less costly, but it cannot achieve both high resolution and large energy range analysis simultaneously
Solution Approach 1:
The patent divides the signal processing into two distinct pathways: a first pathway for high-resolution analysis and a second pathway for large energy range analysis. Each pathway is optimized for its specific function, allowing the system to simultaneously achieve both high resolution and large energy range capabilities without requiring a single complex pathway to do both.
Solution Approach 2:
The patent creates a multi-functional signal processing system where two separate pathways handle different analytical needs. The first pathway processes signals for high-resolution isotope identification, while the second pathway processes signals for large energy range analysis, making the overall system versatile enough to handle multiple types of nuclear spectroscopy measurements simultaneously.
2Adaptability or versatility
If multiple analog signal processing pathways are used to achieve both high resolution and large energy range analysis, then analytical capabilities are improved, but system size and cost increase
Solution Approach 1:
The patent replaces traditional analog signal processing hardware with digital signal processing implemented in a field-programmable gate array (FPGA). This substitution allows multiple signal processing pathways to be implemented in a compact integrated circuit, dramatically reducing the physical size and complexity of the system while maintaining the capability for both high-resolution and large energy range analysis.
Solution Approach 2:
The patent changes the fundamental parameter of signal processing from analog to digital domain. By digitizing the detector signals and performing all processing in the digital domain using an FPGA, the system achieves multiple processing pathways with reduced hardware complexity and smaller size, while improving flexibility and reconfigurability.
3Adaptability or versatility
If multiple analog signal processing pathways are used to achieve both high resolution and large energy range analysis, then analytical capabilities are improved, but system cost increases
Solution Approach 1:
The patent replaces expensive analog signal processing hardware with a digital implementation using an FPGA. This substitution significantly reduces component count, simplifies manufacturing, and lowers system cost while maintaining or improving analytical capabilities. The FPGA-based approach allows both high-resolution and large energy range processing pathways to be implemented in a single integrated device.
Solution Approach 2:
The patent merges the functionality of multiple separate analog signal processing pathways into a single integrated digital processing system. By combining the high-resolution pathway and large energy range pathway into one FPGA-based system, the patent eliminates the need for separate hardware systems, reducing overall cost and simplifying manufacturing.
