Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wire stripping methods are inefficient and hazardous, especially for large quantities of wire, as they require manual adjustment and can be time-consuming, and often result in either incomplete cutting or damage to the wire core due to the need for precise blade positioning.
Innovation Solution
A self-adjusting wire stripping device with tensioned cutting blades and variably sized wire feed channels, using spring, elastic, or magnetic biasing to ensure consistent cutting force across different wire diameters and jacket thicknesses, allowing for manual or powered operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual wire stripping methods are used, then flexibility and control are improved, but productivity and time efficiency deteriorate
Solution Approach 1:
The wire stripping device automatically adjusts the blade position to match different wire diameters without requiring manual intervention. The spring-loaded mechanism self-regulates the cutting depth based on the wire size being processed, eliminating the need for operators to manually adjust settings for each wire type while maintaining high processing speed
Solution Approach 2:
The device incorporates a dynamic blade positioning system where the cutting blade can move vertically along the wire feed channel under spring tension. This dynamic adjustment allows the blade to automatically adapt to different wire diameters during operation, combining the flexibility of manual adjustment with the speed of automated processing
2Device complexity
If fixed blade position is used, then device complexity is reduced, but adaptability to different wire sizes deteriorates
Solution Approach 1:
The wire feed channel features localized variations in geometry, including tapered sections and specific curvature profiles that guide wires of different diameters to the correct blade position. This local geometric customization allows a single blade position to effectively serve multiple wire sizes without requiring complex adjustable mechanisms
Solution Approach 2:
The device utilizes spring tension as a variable parameter to control blade pressure and position. By adjusting the spring tension, the system can adapt to different wire diameters and jacket thicknesses, providing versatility while maintaining a relatively simple fixed blade mounting structure
3Reliability
If blade cuts deeper to remove thick jackets, then stripping effectiveness is improved, but wire core damage risk increases
Solution Approach 1:
The wire feed channel is designed with preliminary guiding features that position the wire and jacket before they reach the cutting blade. The channel geometry pre-aligns the jacket thickness relative to the blade position, ensuring that the blade cuts only the intended portion of the jacket without penetrating into the wire core, even for thick-jacketed wires

Function Achieved in This Case
The device enables easy and safe stripping of various wire sizes and shapes with minimal user adjustment, reducing labor and risk of wire damage, while promoting efficient recycling by automating the process.
Implementation Method 1
The blades are preferably configured with a means to bias them toward the axially running wire, such as with spring tensioning or elastic tensioning, or magnetic or hydraulic biasing
Implementation Method 2
The blades are preferably configured with a means to bias them toward the axially running wire, such as with spring tensioning or elastic tensioning
Implementation Method 3
The blades are preferably configured with a means to bias them toward the axially running wire, such as with spring tensioning or elastic tensioning, or magnetic or hydraulic biasing
Implementation Method 4
The blade in such a device is positioned to cut through the insulating jacket surrounding the wire only, therefor allowing the jacket to be split along the cut line and then removed without severing the metal wire

AI summary
A device for removing an insulation jacket from a wire core of an insulated wire or cable is provided for encouraging recycling. The device employs cutting blades engaged to a first roller to cut a slice along the length of an inserted insulated wire or cable. A frictional engagement between the distal edge of the blade and an opposing recess surface provides for translation of the length of wire through the device during rotation of one or both of the blade and recess surface. Translational movement of the blades and a biasing force can enhance the frictional engagement and provide a distance of travel to prevent cutting of the insulated wire or cable.
