Inductive Cable Film Removal Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing cable films from cable ends are inefficient, often requiring partial removal of the cable jacket and complex devices, and can cause mechanical damage to underlying conductor structures due to the low strength of cable films compared to cable jackets.
Innovation Solution
A method using inductive heating to create a defined damaged region in the cable film, allowing for contactless and precise thermal damage without heating the cable jacket, followed by relative movement to separate the cable film section from the rest, enabling easy and safe removal without mechanical damage to underlying layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal treatment is applied to remove cable film, then the cable film can be removed, but the cable jacket must be partially removed first and the device becomes complicated
Solution Approach 1:
The patent replaces mechanical cutting and stripping methods with inductive heating. An induction coil generates electromagnetic fields that induce eddy currents in the conductive cable, heating it locally to melt the cable film without requiring mechanical contact or complex form tools. This substitution of mechanical systems with electromagnetic induction simplifies the device structure while maintaining effective cable film removal.
Solution Approach 2:
The patent applies local heating through the induction coil positioned at specific locations along the cable. The electromagnetic field is concentrated to heat only the targeted section of the cable where cable film removal is needed, rather than heating the entire cable or requiring removal of the cable jacket. This localized approach eliminates the need for complex device adaptations for different cable sections.
2Ease of operation
If mechanical cutting is used to remove cable film, then the removal process is simple, but the conductor structure underneath is damaged
Solution Approach 1:
The patent changes the physical state of the cable film from solid to melted by controlling the temperature parameter through inductive heating. The induction coil generates sufficient heat to melt the plastic cable film, causing it to separate cleanly from the conductor structure without mechanical contact. This parameter change approach ensures the conductor structure remains undamaged while achieving effective cable film removal.
3Reliability
If the cable jacket is removed to access the cable film, then the cable film can be treated, but the processing time increases
Solution Approach 1:
The patent extracts and removes only the specific section of cable jacket that covers the area where cable film removal is needed, rather than removing the entire cable jacket. The induction coil is positioned to heat only the targeted section, allowing the cable film to be melted and removed in place. This selective extraction approach minimizes processing time by avoiding unnecessary removal and handling of large portions of the cable jacket.

AI summary
A method for easy, safe and fast removal of a section of a cable film. An end section of a cable has a cable axis, wherein the cable includes a cable jacket and at least one electrically conductive conductor structure and which includes a cable film made from a plastic and applied into one of the conductor structures. A defined damaged region is generated by inductively heating at least that conductor structure on which the cable film is applied such that the cable film applied onto the heated conductor structure is at least partially thermally damaged in the damaged region. The cable film is moved relative to one of the conductor structures, wherein a crack is formed by the relative movement in the damaged region that separates the section of the cable film to be removed from a section of the cable film remaining on the cable.
