Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection methods are used, then operational simplicity is maintained, but inspection efficiency and accuracy deteriorate
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated computer vision system using deep learning algorithms. The system captures images of rail components and uses neural networks to automatically detect defects, substituting human visual inspection with computational analysis to improve efficiency while maintaining accuracy.
Solution Approach 2:
The inspection system performs self-analysis by automatically processing captured images through trained deep learning models. The system independently identifies rail components and detects defects without requiring manual intervention or complex post-processing, enabling autonomous operation that improves productivity.
2Speed
If automated inspection systems are implemented, then inspection speed is improved, but processing time for data analysis increases
Solution Approach 1:
The system performs preliminary actions by capturing and preprocessing rail component images in real-time during inspection. Images are immediately processed through the deep learning model on-site, enabling rapid detection and reducing the time loss associated with later data analysis by performing critical processing during the inspection itself.
Solution Approach 2:
The system extracts only the essential defect detection functionality from complex inspection workflows. By focusing the deep learning model specifically on identifying rail component defects rather than performing comprehensive analysis, the system achieves high inspection speed while minimizing processing time through targeted, efficient computation.
3Measurement precision
If deep learning models are used for defect detection, then detection accuracy is improved, but computational requirements increase
Solution Approach 1:
The system uses lightweight, optimized deep learning models that can be deployed on edge devices with limited computational resources. Rather than relying on complex, resource-intensive models, the patent employs streamlined neural networks that achieve sufficient detection accuracy while consuming minimal energy, making the system practical for field deployment.
4Productivity
If real-time processing is implemented, then inspection efficiency is improved, but detection precision may deteriorate
Solution Approach 1:
The system applies partial action by focusing computational resources on detecting only the most critical rail defects rather than performing exhaustive analysis of all components. This selective approach enables real-time processing efficiency while maintaining sufficient detection precision for safety-critical defects, balancing speed and accuracy through targeted inspection.
