Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable laying methods are used with experience-based stress reduction measures, then the laying process can proceed with simple equipment, but the cable is vulnerable to damage and has low security
Solution Approach 1:
The cable laying channel is divided into multiple discrete points that are segmented according to cable grounding manners, cabling manners, and cable bending types. This segmentation allows for localized stress analysis at each discrete point, enabling precise identification of high-risk sections without requiring complex monitoring of the entire cable length simultaneously.
Solution Approach 2:
Stress analysis calculation is performed on minimum segments containing discrete points before the actual cable laying occurs. By calculating traction forces and side pressures in advance based on segmentation information and measurement information, the system identifies potential stress concentration points beforehand, allowing workers to take preventive measures during the laying process.
2Measurement precision
If multiple segmentation levels are applied to discrete points, then stress analysis precision is improved, but the data processing complexity increases
Solution Approach 1:
A three-level segmentation system is implemented: first-level segmentation by cable grounding manners, second-level segmentation by cabling manners, and third-level segmentation by cable bending types. This hierarchical approach organizes discrete points into progressively finer categories, enabling precise stress analysis at each level while maintaining systematic data management.
Solution Approach 2:
The patent introduces a multi-dimensional classification framework where discrete points are categorized along three independent dimensions (grounding manner, cabling manner, bending type). This dimensional approach allows the system to handle complex segmentation requirements by treating each classification criterion as a separate dimension, making the data processing more structured and manageable.
3Reliability
If real-time stress analysis is performed on each cable segment, then cable protection is enhanced, but the calculation and processing time increases
Solution Approach 1:
The cable path is divided into minimum segments containing discrete points, allowing stress analysis to be performed on smaller, manageable units rather than the entire cable length. This segmentation reduces the computational burden for each analysis cycle while maintaining comprehensive coverage of all critical points.
Solution Approach 2:
Segmentation information and measurement information are prepared in advance before stress analysis calculation. By pre-organizing data about discrete points, their locations, grounding manners, and physical characteristics, the system reduces the time required for actual stress calculation during the laying process.
