Solution Overview

Problem

Conventional wire stripping devices require side-to-side motion, which can lead to user injury and are not ergonomic, and they do not accommodate different wire gauges effectively.

Innovation Solution

A pair of pliers with integrated cutting slots in each jaw, where each pair of slots forms a unique diameter hole to fit specific wire gauges, allowing the pliers to be pulled towards the user for ergonomic stripping, reducing the need for side-to-side motion and enhancing safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional wire stripping devices are used, then wire insulation can be stripped, but the device requires side-to-side motion which can lead to user injury and is not ergonomic

Engineering Contradiction:

Improveergonomic operationVSAvoiduser injury risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional motion direction by positioning the cutting slots on the leading edge of the jaws, allowing the pliers to be pulled toward the user rather than requiring side-to-side motion. This inversion of the stripping action direction improves ergonomics and reduces user injury risk while maintaining effective insulation removal.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The cutting slots are pre-positioned on the leading edge of the jaws before the stripping action begins. This preliminary positioning of the cutting edges ensures that the insulation is engaged and cut immediately as the pliers are pulled toward the user, eliminating the need for side-to-side motion and reducing user injury risk from the start of the operation.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If conventional wire stripping devices are used, then wire insulation can be stripped, but they do not accommodate different wire gauges effectively

Engineering Contradiction:

Improvewire gauge accommodationVSAvoidstripping accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent divides each jaw into multiple cutting slots, with each slot having a unique diameter corresponding to specific wire gauges. This segmentation of the cutting edge into multiple specialized slots allows the device to accommodate various wire gauges effectively while maintaining precise stripping accuracy for each gauge type.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pliers are designed with multiple cutting slots of different diameters in each jaw, making the single device capable of stripping insulation from wires of various gauges. This multi-functionality allows one tool to serve multiple wire size requirements while maintaining accurate stripping for each gauge through the specifically sized cutting slots.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A wire stripping assembly includes a pair of pliers including a pair of handles and a pair of jaws. Each of the jaws has a plurality of cutting slots integrated therein. The cutting slots in each of the jaws forms a hole when the jaws are closed for having a wire positioned therein. The hole formed by each of the cutting slots has a unique diameter with respect to each other. In this way the hole formed by each of the pairs of cutting slots can accommodate a unique gauge of wire with respect to each other. The cutting slots in each of the jaws is positioned on a leading edge of the jaws thereby facilitating the pair of pliers to be pulled toward a user when the user is stripping the insulation from the wire.
