Engineering Contradiction Analysis
1Ease of operation
If manual material completeness detection is used, then operation simplicity is maintained, but detection efficiency and accuracy deteriorate
Solution Approach 1:
The patent replaces the manual mechanical detection system with an automated optical detection system using cameras and deep learning algorithms. The system captures images of target objects and uses neural networks to automatically identify and count materials, eliminating manual inspection while significantly improving detection efficiency and accuracy.
Solution Approach 2:
The detection system performs self-service by automatically capturing images, processing them through the detection algorithm, and generating detection results without human intervention. The system independently completes the entire detection workflow, from image acquisition to result output, thereby maintaining operational simplicity while enhancing productivity.
2Device complexity
If manual material completeness detection is used, then system complexity is low, but detection accuracy deteriorates
Solution Approach 1:
The patent replaces simple manual detection with a sophisticated automated system incorporating cameras, image processing units, and deep learning algorithms. This substitution increases system complexity but dramatically improves detection accuracy by using advanced computational methods to identify and count materials with high precision.
Solution Approach 2:
The system changes the detection parameters from subjective human judgment to objective digital image analysis. By converting visual information into digital data and applying algorithmic processing, the system achieves higher measurement precision while managing complexity through standardized computational procedures.
3Measurement precision
If digital twin technology and deep learning are combined, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent creates a digital twin (virtual model) of the physical production line and target objects. This copy allows the system to simulate and analyze material completeness in a virtual environment, improving detection accuracy by comparing real-world images with their digital counterparts while managing complexity through virtual replication.
Solution Approach 2:
The system performs preliminary actions by pre-training deep learning models with extensive datasets and creating digital twins before actual detection. This preparatory work enhances detection accuracy by establishing robust reference models, while the complexity is managed through one-time setup procedures rather than continuous complexity during operation.
