Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional cable production processes are used, then structural stability is maintained, but installation and removal are laborious and time-consuming
Solution Approach 1:
The cable is divided into modular sections with individual conductive cores that can be independently installed and removed. The filling structure contains multiple single-conductive core cables that can be accessed separately through openings, enabling selective maintenance without replacing the entire cable assembly.
Solution Approach 2:
The elastic blocks provide dynamic, flexible support that adapts to installation and removal operations. The elastic deformation of these blocks allows for easier insertion and extraction of conductive cores while maintaining stable positioning during operation, reducing both installation effort and time.
2Reliability
If arc-shaped reinforcement with spring is added, then cable clamping stability is improved, but device complexity increases
Solution Approach 1:
The spring-loaded elastic blocks automatically adjust to clamp the conductive cores with appropriate force. The system is self-regulating, where the spring pressure naturally maintains stable clamping without requiring external adjustment mechanisms or complex control systems, achieving reliability through self-service operation.
Solution Approach 2:
The elastic blocks change their physical state between deformed and recovered positions to provide clamping force. This parameter change (elastic deformation) enables reliable cable securing through a simple mechanical mechanism rather than complex structural arrangements.
3Volume of moving object
If filling structure with multiple cavities is used, then space utilization is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple single-conductive core cables are merged into a single filling structure containing multiple cavities. This consolidation improves space utilization by organizing conductors in a compact arrangement while the modular cavity design allows each section to be manufactured and assembled separately, offsetting the increased structural complexity.
