Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If low-energy radiation is used to reduce radiation exposure, then radiation safety is improved, but penetration capability deteriorates
Solution Approach 1:
The system dynamically adjusts radiation energy levels based on cargo type detection. The radiation inspection system switches between low-energy mode (for light-load cargo) and high-energy mode (for heavy-load cargo), making the energy parameter variable rather than fixed. This resolves the contradiction by adapting the radiation energy to match the actual penetration requirements of different cargo types.
Solution Approach 2:
The system changes the radiation energy parameter according to the detected cargo characteristics. By detecting whether cargo is light-load or heavy-load and相应ly adjusting the radiation energy level, the system optimizes both safety and penetration capability for different inspection scenarios.
2Reliability
If high-energy radiation is used to improve penetration capability, then inspection accuracy is improved, but radiation exposure increases
Solution Approach 1:
The system uses dynamic energy adjustment based on real-time cargo detection. Rather than always using high energy, the system switches to low-energy mode when cargo is detected as light-load, thereby maintaining inspection accuracy when needed while reducing unnecessary radiation exposure.
Solution Approach 2:
The radiation energy parameter is changed based on cargo type detection results. The system adjusts the energy level to match the actual inspection requirements, using high energy only when heavy-load cargo is detected and low energy otherwise.
3Device complexity
If single inspection mode is used to simplify system complexity, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The radiation inspection system is designed with multi-functionality, capable of operating in different inspection modes (standard mode and rapid mode) and automatically switching between them based on cargo type. This universal design allows a single system to handle diverse inspection scenarios without requiring multiple separate devices.
Solution Approach 2:
The system incorporates dynamic mode switching capability, transitioning between standard inspection mode and rapid inspection mode based on detected cargo characteristics. This dynamic adaptability enables the system to optimize inspection parameters for different cargo types while maintaining a unified device structure.
4Measurement precision
If standard inspection mode with high radiation dose is used for all vehicles, then inspection accuracy is improved, but passing rate deteriorates
Solution Approach 1:
The system changes the radiation dose parameter based on cargo type detection. For light-load cargo detected in rapid inspection mode, the system uses lower radiation dose, thereby improving the passing rate by reducing unnecessary high-dose exposure while maintaining sufficient inspection accuracy when needed.
Solution Approach 2:
The radiation dose level is dynamically adjusted based on real-time cargo detection results. The system transitions between high-dose standard mode and low-dose rapid mode according to cargo characteristics, optimizing both inspection accuracy and vehicle passing rate.
