Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for stripping sheathed cables are inefficient, requiring multiple steps and often damage the underlying conductive material, leading to errors and safety hazards in electrical wiring.
Innovation Solution
A sheathed cable stripper device with a housing containing blades and a tension element, allowing for single-motion cutting and removal of sheathing without damaging the conductors, specifically designed for non-metallic sheathed cables like Romex™.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional cutting and stripping tools are used, then the sheathing can be removed, but the underlying conductive material is damaged
Solution Approach 1:
The stripping action is segmented into two distinct phases: a cutting phase where the first blade incises the sheathing, and a stripping phase where the second blade removes the sheathing. This segmentation allows each blade to be optimized for its specific function, with the cutting edge designed for clean incision and the stripping edge designed for removal without conductor contact.
Solution Approach 2:
The channel acts as an intermediary structure that guides and controls the cable's path through the stripper. It positions the cable at a precise angle relative to the blades, ensuring that the cutting action occurs at the optimal location and that the stripping force is applied in a controlled manner that prevents conductor damage.
2Ease of manufacture
If multiple steps are used for cutting and stripping, then the sheathing can be removed, but the process becomes complex and time-consuming
Solution Approach 1:
The cutting and stripping functions, which are typically performed as separate operations with different tools, are merged into a single device. The housing contains both the cutting blade and stripping blade in predetermined positions, allowing both actions to occur during one cable insertion and pull-through motion.
Solution Approach 2:
The blades are pre-positioned within the housing at specific angles and locations. The channel is pre-configured to guide the cable at the correct orientation. When the cable is inserted, all the necessary cutting and stripping actions are automatically performed in the correct sequence without requiring the operator to adjust or reposition anything.
3Productivity
If aggressive stripping methods are used, then the sheathing can be removed quickly, but precision and safety are compromised
Solution Approach 1:
The stripping device applies different qualities of action at different locations: the first blade applies a sharp, concentrated cutting force at a precise point to incise the sheathing, while the second blade applies a broader, more distributed stripping force along the length of the sheathing. The channel provides localized guidance and support exactly where needed to control the cable's path.
4Ease of manufacture
If repeated cutting and stripping steps are performed, then the sheathing can be removed, but labor time and costs increase
Solution Approach 1:
The stripping process is made continuous through the single-motion design. As the cable is pulled through the housing, the cutting blade continuously incises the sheathing along its length while the stripping blade simultaneously removes it. This eliminates the idle time between separate cutting and stripping operations and removes the need for repeated manual interventions.

AI summary
Disclosed herein is a sheathed cable stripping device and method for using same. A method for stripping and cutting non-metallic sheathed cable (NMSC) using a sheathed cable stripper, the method includes receiving a non-metallic sheathed cable in a wire channel of the sheathed cable stripper; sliding the non-metallic sheathed cable along the wire channel; cutting and removing the sheathing of the non-metallic sheathed cable by pulling the sheathed cable stripper toward the user. In yet other aspects, the sheathed cable stripper reduces time and labor costs associated with wiring while providing a safer, more effective, and efficient manner for cutting and removing sheathing from non-metallic sheathed cable.
