Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Monte Carlo simulation methods are used for modeling radioactive particle release, then measurement precision is improved, but device complexity and time consumption increase significantly
Solution Approach 1:
The patent performs comprehensive Monte Carlo simulations and model validations in advance (off-line) to establish a validated simulation model. This pre-computed model is then used for rapid real-time monitoring without requiring repeated complex simulations during actual operation, thus resolving the contradiction between accuracy and complexity/time
Solution Approach 2:
The patent creates a simplified copy or representation of the complex Monte Carlo simulation model that can be used for real-time monitoring. The validated simulation model serves as a reference that enables accurate release level determination without repeating the full Monte Carlo computation process during real-time operation
2Reliability
If validation measurements with radioactive gas are performed, then reliability of the monitoring system is improved, but harmful factors increase due to radioactive particle emission
Solution Approach 1:
Validation measurements are performed in advance during the model development phase to establish confidence in the simulation model. Once validated, the model can be used for predictions without requiring additional radioactive gas emissions during routine real-time monitoring operations
Solution Approach 2:
The patent uses a simulation model as an intermediary that allows validation to be performed once during model development, after which the validated model can predict release levels without requiring continuous physical validation with radioactive gases during real-time monitoring
3Measurement precision
If off-line simulation model building is performed with multiple specialists, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The comprehensive model building and validation process involving multiple specialists is performed once in advance (off-line). The resulting validated simulation model is then ready for immediate use in real-time monitoring, avoiding the need to repeat the time-consuming model building process during actual monitoring operations
4Object-generated harmful factors
If restricted emissions of radioactive particles are imposed for calibration, then harmful factors are reduced, but measurement precision deteriorates due to limited calibration gas variability
Solution Approach 1:
Comprehensive calibration and validation are performed in advance during model development with adequate radioactive gas emissions. Once the model is validated, it can accurately predict release levels during real-time monitoring without requiring additional calibration emissions, thus maintaining precision while reducing harmful emissions during operation
