Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing technologies are used for investigating mixed radiation fields, then radiation analysis can be performed, but the apparatus becomes large and heavy
Solution Approach 1:
The patent replaces bulky mechanical analogue instrumentation with compact digital processing systems. The pulse discrimination and radiation type determination are performed using digital logic and algorithms rather than physical analogue circuits, dramatically reducing the apparatus weight while maintaining radiation analysis capability
Solution Approach 2:
The scintillator-based detector system is designed to detect multiple radiation types (neutrons and gamma rays) simultaneously using a single integrated apparatus. The pulse discrimination module analyzes pulse characteristics to identify different radiation types, eliminating the need for separate detection systems for each radiation type and thereby reducing overall apparatus weight
2Measurement precision
If existing technologies are used for investigating radiation fields in difficult to access locations, then radiation analysis can be performed, but the apparatus becomes large and heavy
Solution Approach 1:
By substituting heavy analogue instrumentation with digital processing systems, the apparatus becomes compact and portable, enabling deployment in difficult to access locations such as nuclear reactor interiors, particle accelerator beamlines, and security screening positions while maintaining full radiation field investigation capability
3Speed
If analogue instrumentation is used for fast response detection, then speed of response can be achieved, but the apparatus becomes bulky and inefficient
Solution Approach 1:
The patent implements digital processing systems that achieve fast response speeds comparable to or exceeding analogue instrumentation. The pulse discrimination module uses digital signal processing to rapidly analyze pulse characteristics and determine radiation types in real-time, eliminating the need for bulky analogue circuits while maintaining high-speed detection capability
