Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tools for removing the outer insulating jacket from large gauge wires and cables are inadequate, as they require manual strain and are limited in length, posing safety concerns and worker fatigue, with existing tools only capable of stripping small sections or limited lengths.
Innovation Solution
A cable-jacket removal tool featuring a cutting unit with a blade housing and a drive unit that includes a gear train, allowing for the use of a handheld drill to rotate the cutting cylinder, enabling efficient stripping of the jacket along any desired length without manual strain, using interchangeable dies for various cable diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual stripping methods are used for large gauge cables, then the jacket can be removed, but tremendous strain is placed on operators and safety concerns arise
Solution Approach 1:
The patent replaces manual mechanical stripping with a powered mechanical system. A motor-driven cutting wheel with a cutting blade automatically cuts through the cable jacket, eliminating the need for operators to manually pull and strain on the cable. The system uses rotational mechanical energy from the motor to perform the stripping action that previously required significant human force.
2Length of moving object
If existing stripping tools are used, then small sections of jacket can be removed, but the tools are limited to stripping only about 5.75 inches of cable length
Solution Approach 1:
The patent employs a movable cutting wheel that can traverse along the length of the cable. The cutting wheel is positioned on a movable arm or carriage that allows it to travel the full length of the cable being stripped. This dynamic positioning enables continuous stripping over extended lengths, unlike fixed-depth tools that are limited to short sections.
Solution Approach 2:
The cable is first clamped and positioned in the device before stripping begins. The cutting wheel is pre-positioned and the motor is ready to engage. This preliminary setup allows the stripping operation to proceed continuously over the entire cable length without interruption or repositioning of the tool, maximizing productivity.
3Adaptability or versatility
If handheld tools are used for stripping, then the tools are simple and portable, but they cannot accommodate larger gauge cables
Solution Approach 1:
The patent designs a stripping device with an adjustable cutting wheel and movable carriage system that can accommodate various cable sizes and types. The cutting wheel diameter and blade position can be adjusted to handle different cable diameters, and the movable carriage allows the tool to work on cables of varying lengths. This universal design enables a single device to perform stripping on small gauge wires as well as large gauge cables.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool allows for safe and efficient removal of the outer jacket from large gauge wires and cables of any length, reducing operator strain and improving safety by utilizing a powered mechanism that can handle longer lengths without manual effort.
Implementation Method 1
The drive unit includes a gear train, allowing for the use of a handheld drill to rotate the cutting cylinder

AI summary
A cable-jacket removal tool is described. The tool includes cutting unit that provides a cutting cylinder that carries a blade and a die. The blade is adjustable to provide a desired depth of cut into the cable jacket. The die is interchangeable and selectable based on a diameter or gage of cable to be stripped. A drive unit that is adapted to be driven by a common, handheld, battery operated drill is also provided. The drive unit rotates the cutting cylinder and the blade carried thereby about the circumference of the cable. The drill is coupled to the drive unit such that the axis of rotation of the drill and the cutting cylinder are substantially parallel and an operator can easily apply a force on the tool via the drill in a direction substantially parallel to those axes of rotation.
