Cable Stripping Wheel With Perforation Elements for Shield Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable stripping devices often damage the sensitive shielding layer of shielded cables, particularly when attempting to remove the outer protective sheath and underlying shielding foil, which is crucial for maintaining effective electrical shielding.
Innovation Solution
A device with a rolling wheel featuring radially projecting perforation elements that perforate and cut the protective sheath without damaging the shielding layer, combined with a cutting wheel to facilitate sheath removal, and a mechanism to adjust to different cable thicknesses, using centrifugal force for pressure control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rolling wheel is used to cut the protective sheath, then the stripping efficiency is improved, but the shielding layer may be deformed or damaged
Solution Approach 1:
The rolling wheel is equipped with perforation elements at specific locations to create localized perforations in the protective sheath. This allows the cutting action to be concentrated at discrete points rather than distributed across the entire contact surface, reducing the risk of widespread damage to the shielding layer while maintaining effective sheath removal
Solution Approach 2:
The rolling wheel is divided into functional segments: a rolling contour for general contact and perforation elements for targeted cutting. This segmentation allows the device to perform both the cutting function (for efficiency) and the protective function (for shielding layer preservation) simultaneously through different parts of the same component
2Strength
If pressure is increased to cut through the protective sheath, then the cutting capability is improved, but the deformation of the shielding layer increases
Solution Approach 1:
Pressure application is localized to the perforation elements rather than distributed across the entire rolling wheel surface. This concentration of force at specific points enables effective cutting through the protective sheath while limiting the affected area and preventing widespread deformation of the shielding layer
Solution Approach 2:
The perforation elements create preliminary perforations in the protective sheath before the main cutting action occurs. This preliminary action weakens the sheath structure at specific points, allowing subsequent cutting to proceed with reduced pressure requirements and thereby minimizing deformation of the underlying shielding layer
