Solution Overview

Problem

Existing wire strippers face challenges in smoothly performing stripping work on sheath layers of sheathed wires.

Innovation Solution

A wire stripper design featuring a wire stripper body with a first member and a second member, a blade body, a press plate part, and a distance adjusting mechanism, along with guide parts and a helical movement assistance mechanism, to facilitate smooth separation of sheath layers from core wires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional wire stripper design is used, then the structure is simple, but the stripping work cannot be performed smoothly due to obstruction and tilting

Engineering Contradiction:
Improvesmoothness of stripping workVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wire stripper is divided into multiple functional components: a wire stripper body with first and second members, a blade body, a press plate part, guide parts, and a distance adjusting member. Each component performs a specific function (guiding, pressing, cutting), allowing the complex stripping operation to be broken down into manageable segments that work together smoothly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The press plate part acts as an intermediary between the first member and the blade body, pressing the sheathed wire against the blade body during the stripping operation. The guide parts serve as intermediaries to guide the relative motion between the wire stripper body and the sheathed wire, preventing tilting and ensuring smooth helical movement

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the distance between the first member and the second member is not adjustable, then the device structure is simple, but it cannot adapt to different wire sizes and stripping requirements

Engineering Contradiction:
Improveadaptability to different wire sizesVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The distance adjusting member enables dynamic adjustment of the distance between the first member and the second member, transforming a static structure into a dynamic one that can adapt to different wire diameters and stripping requirements. This dynamic adjustment capability allows the wire stripper to accommodate various wire sizes without requiring multiple fixed-size tools

Inventive Principle:
Principle #15Dynamics

AI summary

An object is to provide a wire stripper. The wire stripper includes: a wire stripper body having a first member, a second member and a first passage; a blade body attached to the second member and configured to separate the sheathed wire into a sheath layer and a core wire; a press plate part arranged to the first member so as to face the blade body and having a press surface configured to press the sheathed wire against the blade body; and a distance adjusting member configured to adjust the distance between the first member and the second member. The first member has a first guide part defining a part of the first passage and configured to guide relative motion of the wire stripper body relative to the sheathed wire. The press plate part protrudes on the first passage side from the first guide part.
