Power Cable Jacket Removal Using Motor-Driven Wire Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing cable jackets from sheathed cables are often labor-intensive, risk damaging the interior of the cable, require maintenance-intensive blade configurations, and are limited by the need for stationary and unwieldy devices, which can hinder accessibility and increase downtime.
Innovation Solution
A cable jacket removal device comprising a support frame, a drive shaft, and a motor that selectively rotates to automatically remove the cable jacket by drawing an internal wire through the jacket, eliminating the need for blade configurations and allowing for automatic operation on-site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a blade configuration (e.g., circular saw) is used to cut through the cable jacket, then the cable jacket can be removed, but the risk of damaging the interior of the cable increases and blade maintenance needs increase
Solution Approach 1:
The invention extracts the cutting function from a traditional blade and relocates it to a removable cutting element that can be precisely controlled. The cutting element is separated from the main device body, allowing for precise positioning and controlled engagement with the cable jacket only, preventing damage to internal components.
Solution Approach 2:
The invention changes the physical state and properties of the cutting mechanism by using a removable cutting element that can be adjusted in depth and position. This allows precise control over the cutting parameters, ensuring the blade only penetrates the jacket thickness without reaching the conductors inside.
2Productivity
If a blade configuration is used to remove the cable jacket, then the jacket can be cut, but the blade wears out prematurely requiring maintenance and downtime
Solution Approach 1:
The invention implements a disposable or easily replaceable cutting element that can be discarded after wear and recovered for replacement. The cutting element is designed to be economically replaceable rather than maintained, eliminating downtime for blade sharpening or replacement while maintaining high productivity.
Solution Approach 2:
The cutting element is designed as a low-cost, short-lived component that can be easily replaced. This disposable approach eliminates the need for expensive blade maintenance while ensuring continuous operation, as the cheap cutting element can be quickly swapped without affecting overall device value or requiring complex maintenance procedures.
3Productivity
If a stationary and unwieldy removal device is used, then the cable jacket can be removed, but the device becomes difficult to operate and accessibility is limited
Solution Approach 1:
The invention transforms the device from a stationary configuration to a dynamic, portable system. The support frame with drive shaft and motor assembly can be moved to different locations, and the cutting element can be dynamically engaged and disengaged from the cable, allowing operation in various field conditions and improving accessibility.
Solution Approach 2:
The device is segmented into modular components including a support frame, drive shaft assembly, motor, and removable cutting element. This segmentation allows each component to be independently positioned, adjusted, and operated, making the overall system more maneuverable and easier to operate in confined or difficult-to-reach locations.

AI summary
A cable jacket removal device is used to selectively remove a sheath from a length of a sheathed cable. The cable jacket removal device includes a support frame, a drive shaft, and a motor. The support frame removably couples the removal device to the cable to be stripped. The drive shaft is coupled to the support frame. The motor is coupled to the drive shaft to selectively rotate the drive shaft to cause the removal device to travel along the cable to automatically remove a cable jacket from a predefined distance of the cable.
