Solution Overview

Problem

Existing insulation-stripping tools face challenges in efficiently stripping insulation from cables, particularly in difficult-to-access regions, where tools often require complex maneuvers to strip insulation both transversely and longitudinally.

Innovation Solution

The design of an insulation-stripping tool with a pivoting body featuring a first insulation-stripping cutter and a second cutter, arranged circumferentially offset, allowing for easy transition between cutting engagement and release positions through a pulling motion on the cable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional insulation-stripping tool is used with fixed cutters, then the tool structure is simple, but the ease of operation deteriorates due to complex maneuvers required to strip insulation both transversely and longitudinally

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The first insulation-stripping cutter is mounted pivotably on the pivoting body, allowing it to move between a cutting engagement position and a release position. This dynamic mounting enables the cutter to be easily repositioned during operation, improving ease of use while managing device complexity through a single pivot mechanism

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The tool incorporates two distinct insulation-stripping cutters (first and second cutters) with different functions - one for transverse stripping and one for longitudinal stripping. This segmentation allows each cutter to be optimized for its specific task, improving operational efficiency without requiring overly complex mechanisms

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If two insulation-stripping cutters are provided for both transverse and longitudinal stripping, then the versatility is improved, but the device complexity increases

Engineering Contradiction:
ImproveversatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Both the first and second insulation-stripping cutters are mounted on the same pivoting body, allowing them to be positioned and used for different stripping operations. This multi-functional design enables a single tool to perform both transverse and longitudinal insulation stripping, enhancing versatility while keeping the overall structure manageable through shared mounting components

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

3Ease of operation

If the first insulation-stripping cutter is mounted pivotably between cutting engagement and release positions, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The first insulation-stripping cutter is mounted pivotably on the pivoting body, allowing it to move between a cutting engagement position and a release position. This dynamic mounting enables the cutter to be easily repositioned during operation, improving ease of use while managing device complexity through a single pivot mechanism

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pivotable mounting mechanism for the first cutter is integrated with the pivoting body that also supports the second cutter. This merging of functions allows both cutters to be positioned and operated from a common structural platform, reducing overall device complexity compared to having separate mounting mechanisms for each cutter

Inventive Principle:
Principle #5Merging (Combining)
