Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all radiation data is transmitted to the computer, then complete radiation detection is achieved, but computational load increases significantly
Solution Approach 1:
The patent extracts and transmits only the essential data (radiation direction and electron position information) to the computer, while filtering out unnecessary data about radiation that did not undergo Compton scattering. This extraction principle reduces the data volume transmitted to the computer, thereby reducing computational load while maintaining the reliability of radiation detection analysis.
2Adaptability or versatility
If radiation data from non-Compton scattering events is included, then detection coverage is improved, but data usefulness decreases
Solution Approach 1:
The patent applies local quality by selectively processing and transmitting only the data related to Compton scattering events, which are the specific local phenomenon of interest. The system distinguishes between useful data (Compton scattering events with electron production) and useless data (other radiation events), thereby maintaining high data usefulness while preserving detection coverage for the target phenomenon.
3Productivity
If trigger signals are used to control data transmission, then data transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by using trigger signals generated in advance based on electron detector signals to control the timing of data transmission. The trigger signal is prepared before the actual data transmission occurs, allowing the system to efficiently control when data is sent to the computer. This preliminary action approach improves data transmission efficiency while adding minimal system complexity compared to continuous monitoring and filtering approaches.
