Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dual-energy state calibration is performed individually for each system, then identification accuracy is improved, but the complexity and time consumption of the marking procedure increases significantly
Solution Approach 1:
The system performs automatic marking by utilizing the accelerator's own dual-energy state data to generate classification parameters without requiring external calibration equipment or manual procedures. The accelerator subsystem serves itself by using its inherent pulse current and energy spectrum characteristics to establish the classification curves automatically.
Solution Approach 2:
The system uses feedback from the accelerator's dual-energy state measurements to dynamically adjust and generate classification parameters. The marking process continuously monitors the accelerator state and adjusts the classification curves based on the measured energy spectra and pulse current characteristics, ensuring accurate identification without manual intervention.
2Reliability
If re-marking is performed when accelerator state fluctuates, then identification stability is improved, but the loss of time and operational efficiency increases
Solution Approach 1:
The classification parameters are made dynamic rather than static, automatically adapting to changes in accelerator state. The system continuously updates the classification curves based on real-time measurements of the accelerator's dual-energy state, allowing the marking to remain accurate without requiring periodic re-marking procedures.
Solution Approach 2:
The system performs preliminary automatic marking during the initial system setup and after any accelerator maintenance, establishing baseline classification parameters that are then continuously self-adjusted. This preliminary action eliminates the need for subsequent manual re-marking operations during normal operation.
3Device complexity
If a single set of classification parameters is used across multiple systems, then device complexity and calibration time are reduced, but identification precision decreases due to system variations
Solution Approach 1:
The system automatically adjusts the classification parameters based on the specific dual-energy state characteristics of each accelerator system. By measuring the energy spectra and pulse current characteristics of the particular system being used, the marking procedure generates optimized classification curves that are tailored to that system's specific parameters, ensuring high identification precision without requiring complex manual calibration.
