Engineering Contradiction Analysis
1Productivity
If automatic target detection is implemented using machine learning, then detection efficiency is improved, but detection accuracy decreases due to varying imaging conditions and target types
Solution Approach 1:
The system dynamically adjusts the adjustment range of imaging parameters based on the operation state of the specific target detection unit. When the detection unit is operating, the parameter adjustment range is restricted to values that maintain high detection accuracy, whereas when not operating, a broader range is allowed for general imaging flexibility.
Solution Approach 2:
The patent changes the parameter settings by implementing different adjustment ranges for imaging parameters (such as gain, depth, focus) depending on whether the specific target detection unit is active. This parameter adaptation ensures optimal imaging conditions for both automated detection and manual operation modes.
2Measurement precision
If parameter adjustment range is restricted during detection operation, then detection accuracy is improved, but user flexibility decreases
Solution Approach 1:
The system dynamically switches between two operational modes: when the specific target detection unit is active, the parameter adjustment range is automatically restricted to optimize detection accuracy; when inactive, the full adjustment range is restored for user flexibility in general imaging tasks.
Solution Approach 2:
The system automatically manages parameter adjustment ranges based on the operational state of the detection unit without requiring manual user intervention. The control unit self-adjusts the parameter constraints, eliminating the need for users to manually switch between different parameter settings for detection and general imaging modes.
3Measurement precision
If different parameter settings are used for different target types, then detection accuracy is improved, but system complexity increases
Solution Approach 1:
The system implements a universal control mechanism that manages multiple imaging parameters (gain, depth, focus, etc.) through a single unified interface. The control unit handles all parameter adjustments based on the detection unit's operational state, eliminating the need for separate parameter management for each target type or mode.
Solution Approach 2:
The control unit automatically selects and applies appropriate parameter settings based on the operational state of the specific target detection unit. This self-service approach eliminates manual parameter management complexity while maintaining optimal settings for both detection and general imaging modes.
