Solution Overview

Problem

Existing stripping tools for electrical conductors lack the ability to perform longitudinal cuts automatically, requiring manual intervention and exerting significant forces to remove insulating jackets.

Innovation Solution

A tool with a displaceable first cutting element guided along a longitudinal contour within the tool housing, allowing for efficient longitudinal cutting of the insulating jacket, and optionally featuring second and third cutting elements for radial cuts, with adjustable depth and carriage mechanisms for precise handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing stripping tools are used, then the insulating sheath can be removed, but a longitudinal cut cannot be made or requires additional manual steps

Engineering Contradiction:
Improvestripping efficiencyVSAvoidoperational simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent combines the longitudinal cutting function with the radial cutting elements into a single integrated tool. The first cutting element is displaceably mounted along a guide contour to perform longitudinal cutting, while second and third cutting elements perform radial cutting, merging multiple cutting operations into one tool that eliminates the need for separate manual longitudinal cutting steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The tool is designed with multi-functionality to perform both longitudinal cutting (via the first cutting element on the guide contour) and radial cutting (via second and third cutting elements). This universal design allows the single tool to complete the entire stripping process including making longitudinal cuts through the insulating sheath, eliminating the need for additional specialized tools or manual intervention.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If significant forces are applied to remove the insulating jacket, then the jacket can be removed, but the internal conductor may be damaged

Engineering Contradiction:
Improvejacket removal easeVSAvoidconductor integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cutting process is segmented into multiple precise cuts: the first cutting element makes a longitudinal cut along the guide contour, while second and third cutting elements make radial cuts. This segmentation of the cutting action into controlled segments allows the insulating sheath to be divided into manageable sections that can be removed without requiring significant force, thereby protecting the internal conductor from damage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tool performs preliminary cutting actions by making precise longitudinal and radial cuts through the insulating sheath before removal. These preliminary cuts pre-weaken and separate the sheath structure, allowing it to be easily peeled away without applying significant force that could damage the internal conductor.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the cutting depth is fixed, then the tool structure is simple, but it cannot adapt to different sheath thicknesses

Engineering Contradiction:
Improveadaptability to sheath thicknessVSAvoidtool structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The tool incorporates adjustable cutting elements with variable positioning mechanisms that allow the cutting depth to be dynamically adjusted according to different insulating sheath thicknesses. The first, second, and third cutting elements can be positioned at different depths along their respective guide contours, providing adaptability to various sheath thicknesses while maintaining a relatively simple overall tool structure.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a tool for stripping an electrical conductor, comprising a tool housing, wherein the tool housing has a receiving channel for receiving the electrical conductor, and a first cutting element, wherein the first cutting element can be positioned against the inserted electrical conductor via an adjusting element such that the first cutting element cuts into an insulating sheath of the electrical conductor. The first cutting element is slidably mounted along a guide contour in a longitudinal direction of the tool.
