Gripping Device for Independent Twisted Conductor Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripping devices are unable to independently grip and test two adjacent conductors that are twisted together, and they are not suitable for handling conductors with small diameters or those arranged between other conductors.
Innovation Solution
A gripping device with a first and second gripping jaw and a middle jaw, where the jaws are displaceable along a transverse axis, allowing for independent gripping and movement of two conductors, with T-shaped middle jaw for stiffness and arcuate recesses for secure holding, and actuators for precise movement, enabling testing of individual conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single bar-shaped middle jaw is used to grip multiple conductors together, then the device can handle twisted conductors as a unit, but it becomes impossible to grip and test individual conductors independently
Solution Approach 1:
The middle jaw is divided into multiple independent gripping elements (first middle gripping element, second middle gripping element, etc.) that can move independently relative to each other. This segmentation allows the device to grip multiple conductors simultaneously while still enabling independent manipulation and testing of each conductor, resolving the contradiction between handling conductors as a unit and testing them individually.
2Adaptability or versatility
If gripping jaws are designed for general-purpose use, then they can handle various conductor configurations, but they cannot accommodate conductors with small diameters arranged between other conductors
Solution Approach 1:
The gripping elements are designed with dynamic movement capabilities, allowing them to move toward and away from the central axis independently. This dynamic design enables the jaws to adapt to different conductor diameters and positions, including small diameter conductors arranged between other conductors, while maintaining versatility for various conductor configurations.
Solution Approach 2:
Different gripping elements have different geometries and movement ranges optimized for specific gripping tasks. The first and second gripping jaws can be independently positioned to accommodate conductors of different sizes and locations, providing local optimization for gripping small diameter conductors while maintaining overall versatility.
3Stability of the object's composition
If conductors are gripped together due to twisting, then the twisted structure is preserved, but testing procedures cannot be carried out on individual conductors
Solution Approach 1:
The gripping device segments the gripping function into multiple independent gripping elements, each capable of independently gripping and releasing individual conductors. This allows the twisted structure to be preserved during handling while enabling individual conductors to be isolated for testing procedures, as each gripping element can control its grip independently.
