Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rope replacement cart is used to achieve linear pulling and pushing movement of the steel wire rope, then the rope replacement process can be performed, but a slipping phenomenon occurs resulting in low efficiency and damage to related device and new ropes
Solution Approach 1:
The patent implements a feedback control system that detects the actual movement speed of the rope and compares it with the expected speed. Based on the speed difference, the control component adjusts the driving roller's rotation speed to maintain synchronous movement and prevent slipping. This closed-loop feedback mechanism directly addresses the slipping problem while maintaining high replacement efficiency.
Solution Approach 2:
The patent employs dynamic adjustment of the driving roller's rotation speed based on real-time rope movement conditions. The control component continuously modifies the driving parameters to adapt to varying rope tension, friction conditions, and movement speeds, thereby preventing slipping and optimizing replacement efficiency under different operating conditions.
2Duration of action of stationary object
If the service life of the hoisting steel wire rope is extended, then replacement frequency is reduced, but the strength of the rope decreases due to wire breaking, wear, and corrosion
Solution Approach 1:
The patent implements preliminary detection and assessment of rope conditions before replacement is necessary. By continuously monitoring rope strength, wear, corrosion, and other degradation parameters, the system can identify ropes that need replacement before they fail, allowing for planned maintenance that extends service life while ensuring safety standards are met.
Solution Approach 2:
The patent replaces traditional mechanical inspection methods with advanced detection systems that use sensors, detectors, and electronic monitoring to assess rope conditions. This substitution enables more precise and frequent monitoring of rope degradation, allowing for better maintenance scheduling that optimizes both service life and strength.
3Power
If the number of shaft hoists in large coal mines is increased, then coal transportation capacity is improved, but the workload and time for rope replacement increases
Solution Approach 1:
The patent implements self-service rope replacement capabilities where the system can automatically detect rope conditions, initiate replacement procedures, and complete the swap without requiring extensive manual intervention. The automated detection and control systems reduce the time needed for each replacement operation, allowing mine operators to maintain higher hoist numbers without proportionally increasing replacement time costs.
Solution Approach 2:
The patent enables continuous monitoring and replacement operations that minimize downtime between hoist operations. By having detection systems running continuously and maintaining ready-to-replace rope inventories, the system can perform rapid replacements when needed, ensuring that the increase in hoist number does not translate to proportional increases in replacement time loss.
