Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Stripping insulation from large gauge conducting wires is a time-consuming task typically requiring manual cutting with a utility knife or wire-stripping hand tool.

Innovation Solution

A wire stripping die configured for a crimping tool, featuring grooves with radial and longitudinal ridges that cut insulation material efficiently when the die portions are closed, allowing easy removal of insulation from the conductor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual wire stripping with utility knife or hand tool is used, then the wire stripping task can be completed, but it is time-consuming and labor-intensive

Engineering Contradiction:

Improvewire stripping speedVSAvoidtime required for wire stripping

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical wire stripping with an automated mechanical system integrated into the crimping tool. The die incorporates cutting edges that automatically cut and separate the insulation from the conductor when the crimping tool is actuated, eliminating the need for separate manual stripping operations with utility knives or hand tools.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent combines the wire stripping function with the crimping tool by integrating cutting edges into the die structure. This merging of functions allows the operator to perform both stripping and crimping operations with a single tool, eliminating the need for separate stripping tools and reducing overall task time.

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If a wire stripping die is integrated into the crimping tool, then wire stripping becomes automated and faster, but the device complexity increases

Engineering Contradiction:

Improvewire stripping efficiencyVSAvoidcrimping tool structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The die is designed as a separate, removable component with integrated cutting edges, allowing it to be independently manufactured and then assembled into the crimping tool. This segmentation enables the stripping function to be added without redesigning the entire crimping tool, thereby limiting the increase in overall device complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The die serves multiple functions: it acts as both the crimping die and the wire stripping tool. By making the die multi-functional, the patent avoids adding separate stripping mechanisms to the crimping tool, thereby minimizing the increase in device complexity while still achieving automated stripping.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A wire stripping die is configured to be coupled to a crimping tool. The stripping die includes a die body, a first ridge, and a second ridge. The die body includes a first side, a second side, and a groove extending at least partially between the first side and the second side. The groove extends along an axis. The first ridge protrudes from a surface of the groove toward the axis by a first distance. The first ridge extends along at least a portion of the perimeter of the groove and extends at least partially around the axis. The second ridge protrudes from the surface of the groove toward the axis, and the second ridge extends parallel to the axis along at least a portion of the groove.
