Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional radioactivity measurement method is used to obtain accurate results, then measurement precision is improved, but measurement time becomes excessively long (2-3 days or larger)
Solution Approach 1:
The patent performs preliminary action by measuring and storing radioactivity decay characteristics at multiple time points during a first time period to create a database. This preliminary data collection enables rapid estimation of nuclide-based radioactivity decay characteristics for subsequent time periods without requiring continuous long-term measurement, thus resolving the contradiction between measurement accuracy and measurement time.
Solution Approach 2:
The patent creates a copy of the radioactivity decay pattern through the database formed by storing time-energy relationship data sets. By using this database copy, the system can estimate future radioactivity values through data random extraction techniques (including Monte Carlo simulations) without physically waiting for the actual decay process to complete, thereby reducing measurement time while maintaining accuracy.
2Measurement precision
If real-time accumulation of radioactivity data is performed, then measurement precision is improved, but productivity deteriorates due to long analysis time
Solution Approach 1:
The system performs preliminary measurement and storage of radioactivity decay characteristics during a first time period, creating a database that can be rapidly queried. This preliminary action enables fast estimation of radioactivity values for subsequent time periods, significantly improving productivity while maintaining measurement precision through the stored decay pattern data.
Solution Approach 2:
The patent replaces the mechanical process of continuous real-time accumulation and analysis with a data-driven approach using stored time-energy relationship data sets. By using database queries and data random extraction techniques (including Monte Carlo simulations), the system achieves rapid analysis without the lengthy mechanical process of continuous measurement, thus improving productivity.
3Measurement precision
If measurement is performed on nuclides with low sensitivity to radioactive decay, then measurement precision is maintained, but measurement time becomes excessively long
Solution Approach 1:
The patent performs preliminary measurement of radioactivity decay characteristics and stores them in a database. For nuclides with low sensitivity to radioactive decay, this preliminary data collection enables rapid estimation of current radioactivity values by querying the stored decay patterns, eliminating the need for prolonged measurement while maintaining measurement precision.
Solution Approach 2:
The patent creates a database copy of radioactivity decay patterns that can be rapidly queried to estimate current radioactivity values. This copy allows the system to maintain measurement precision for low-sensitivity nuclides by using stored decay characteristic data rather than requiring continuous long-term measurement, thus resolving the time contradiction.
