Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all radiation data is transmitted to the computer for analysis, then complete radiation detection coverage is achieved, but the computer becomes overloaded and data processing efficiency decreases
Solution Approach 1:
The patent extracts and transmits only the essential data elements (hit signals and timing information) to the computer, rather than transmitting all raw radiation detection data. This selective extraction reduces the data burden on the computer while maintaining the ability to perform complete radiation analysis, thereby resolving the contradiction between detection coverage and processing efficiency.
Solution Approach 2:
The patent segments the data transmission process by dividing radiation detection data into distinct components: hit signals indicating radiation detection events and timing information for correlation analysis. This segmentation allows the system to transmit minimal necessary data to the computer while maintaining complete analytical capability, thus improving processing efficiency without sacrificing detection reliability.
2Loss of information
If data from both radiation detector and electron detector is continuously transmitted, then complete detection information is available, but the data volume increases computational load
Solution Approach 1:
The patent performs preliminary processing of detection data by generating hit signals and timing information at the detector level before transmission to the computer. This preliminary action consolidates raw detection data into essential information elements, ensuring no detection information is lost while significantly reducing the computational load required for subsequent analysis.
Solution Approach 2:
The patent changes the parameter representation of detection data by converting continuous analog detection signals into discrete digital hit signals and timing parameters. This parameter transformation reduces the data volume requiring computational processing while preserving all essential detection information needed for radiation analysis.
3Quantity of substance
If radiation data including non-scattered radiation is analyzed, then all detected radiation is accounted for, but data usefulness decreases due to inability to perform Compton scattering analysis
Solution Approach 1:
The patent introduces timing information as an intermediary parameter that enables the computer to distinguish between Compton-scattered radiation events and non-scattered radiation events. By correlating timing data from both detectors, the system can identify valid Compton scattering events even within the broader dataset, thereby maintaining data usefulness while accounting for all detected radiation.

AI summary
A detecting apparatus that detects radiation includes a container containing gas, an electron detector located inside the container, the electron detector detecting an electron generated by Compton scattering to generate an analog signal, a drift electrode facing the electron detector, a radiation detector detecting radiation scattered by Compton scattering to generate an analog signal, a first read circuit digitizing the analog signal generated by the radiation detector to generate first data and storing the first data in a first buffer, and a second read circuit digitizing the analog signal generated by the electron detector to generate second data. The first read circuit transmits first final data including the first data stored in the first buffer to an external computer in response to a first trigger signal.
