Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for stripping shielded cables are time-consuming, require dexterity and experience, and often damage the shielding layer, making it difficult for inexperienced users or automated processes to achieve reliable and safe cable connections.
Innovation Solution
A device with a support roller arrangement and a work wheel arrangement that applies pressure and rotates around the cable, using rolling wheels and cutting wheels with different edge geometries to wear down the protective sheath without damaging the shielding layer, and optionally applying electrical voltage for spark erosion to facilitate clean separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual stripping or traditional mechanical aids are used, then the operator has control over the process, but the process is time-consuming and requires dexterity and experience
Solution Approach 1:
The work wheel arrangement automatically adjusts its pressing force against the cable through the rotational mechanism, eliminating the need for operator skill to control pressure. The system self-regulates the stripping force based on the cable characteristics, enabling inexperienced users or automated processes to operate efficiently without requiring dexterity or experience.
2Productivity
If traditional mechanical aids are used, then the stripping process is faster than manual methods, but the shielding layer is easily damaged
Solution Approach 1:
The work wheel arrangement applies pressing force locally and selectively to the protective sheath material, with the force distribution designed to wear down the sheath without penetrating to the shielding layer. The localized action at the contact point between the work wheel and cable allows precise control of material removal while preserving the underlying shielding structure.
Solution Approach 2:
The rotational work wheel arrangement performs preliminary wearing down of the protective sheath before complete separation occurs. This gradual material removal prepares the sheath for clean detachment while maintaining shielding layer integrity, preventing sudden forceful actions that could damage the shielding.
3Measurement precision
If electronic detection devices are used, then the cutting point can be determined, but the detection is too late and the shield or conductor is already damaged
Solution Approach 1:
The work wheel arrangement performs preliminary wearing down of the protective sheath before complete separation occurs. This gradual material removal prepares the sheath for clean detachment while maintaining shielding layer integrity, preventing sudden forceful actions that could damage the shielding.
4Reliability
If manual stripping is used, then the shielding layer can be preserved, but the process is time-consuming
Solution Approach 1:
The rotational motion of the work wheel arrangement creates continuous mechanical action against the protective sheath, wearing down the material through repeated contact and friction. This vibratory-like mechanical action accelerates sheath removal while the controlled force application preserves the shielding layer, achieving both speed and reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick, safe, and reliable stripping of shielded cables by inexperienced users or in automated processes, ensuring the shielding layer remains intact and the process is efficient, reducing the time required for cable connections.
Implementation Method 1
the rolling wheel rolling off on the sheath along a cutting region wears down the material of the sheath until finally the sheath can no longer withstand the pressure of the rolling wheel and it severs through the sheath
Implementation Method 2
the work wheel guide can have an eccentric weight distribution with respect to the axis of rotation, wherein a centrifugal force causing the pressure force acts on the work wheel guide, when the rotation base, with the work wheel guide arranged thereon via the linear guides, rotates around the axis of rotation
Implementation Method 3
an electrical voltage can be applied to at least one element of the work wheel arrangement, in particular to a rolling wheel and/or cutting wheel and/or an electrode. This electrical voltage can generate sparks that weaken the material of the protective sheath and/or a boundary layer in a targeted manner and allow for clean separation

AI summary
A device and method for stripping a cable has at least one support roller arrangement and a work wheel arrangement. The end of the cable to be stripped can be clamped with the application of a pressure force between the work wheel arrangement and the support roller arrangement. The unit made up of the work wheel arrangement and the support roller arrangement can be driven to rotate around the cable and to roll off thereon.
