Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual recognition is used for security inspection, then the system is simple to operate, but the accuracy and efficiency of dangerous item detection deteriorates
Solution Approach 1:
The recognition system is divided into multiple functional modules: object feature extraction module, dangerous item region segmentation module, preliminary classification module, and fine-grained recognition module. Each module performs a specific task in the detection process, allowing the complex system to be managed and optimized independently while achieving high detection accuracy
Solution Approach 2:
A convolutional neural network serves as an intermediary between the raw X-ray images and the final classification results. The CNN extracts meaningful features from images and transforms them into a format suitable for classification, bridging the gap between image data and detection decisions
2Productivity
If manual recognition is used for security inspection, then the equipment cost is low, but the productivity and inspection efficiency deteriorates
Solution Approach 1:
The system performs automated feature extraction, region segmentation, and classification without requiring manual intervention. The convolutional neural network automatically learns to identify dangerous items from training data, and the reinforcement learning algorithm autonomously optimizes the detection process, enabling the system to serve itself and achieve high productivity
Solution Approach 2:
The manual mechanical inspection process is replaced with an automated computational system. Instead of security personnel manually examining images, the system uses algorithms including convolutional neural networks and reinforcement learning to automatically detect and classify dangerous items, significantly improving inspection speed and efficiency
3Reliability
If manual recognition is used for security inspection, then the system is easy to operate, but the reliability and consistency of detection results deteriorates
Solution Approach 1:
The system incorporates feedback mechanisms where classification results are evaluated against confidence thresholds. When detection confidence is insufficient, the system automatically triggers fine-grained recognition to re-examine suspicious regions, ensuring reliable and consistent detection results while maintaining operational simplicity through automated decision-making
4Measurement precision
If fine-grained recognition is applied to all items, then the detection accuracy improves, but the inspection time and computational resources increase
Solution Approach 1:
Fine-grained recognition is applied selectively rather than universally. The system performs detailed analysis only on regions identified as potentially dangerous by the preliminary classification, applying computational resources efficiently to where they are most needed while maintaining high detection accuracy and reducing overall inspection time
