Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire rope inspection devices face challenges in precisely controlling the movement of detection coils to approach wire ropes closely, leading to increased processing load and complexity in remote operation.
Innovation Solution
The proposed wire rope inspection device incorporates an urging unit that uses elastic force to move the detection unit close to the wire rope during inspection, eliminating the need for fine motor control and reducing processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a motor or driving force is used to move the detection coil to the inspection position, then the detection coil can be positioned close to the wire rope for high precision inspection, but the control processing load increases due to the need for fine movement control
Solution Approach 1:
The patent replaces the motor-driven mechanical positioning system with an elastic urging mechanism. The detection coil is equipped with an elastic member that automatically urges it toward the wire rope, eliminating the need for complex motor control processing while achieving close positioning for high precision detection.
Solution Approach 2:
The detection coil is designed to be self-positioning through the elastic urging mechanism. The elastic member automatically pushes the detection coil toward the wire rope without requiring external control signals, enabling the system to self-adjust to the optimal inspection position.
2Measurement precision
If the detection coil is kept close to the wire rope during normal operation, then inspection precision is maintained, but the wire rope may come into contact with the detection coil causing damage or interference
Solution Approach 1:
The patent implements a dynamic positioning system where the detection coil's position changes based on operational mode. During inspection, the elastic member urges the coil close to the wire rope for high precision. During normal operation, the drive unit moves the coil away to prevent contact, with the elastic member ready to quickly restore close positioning when inspection is needed.
