Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wire processing machines struggle with incomplete stripping of insulation layers from busbars and coil elements, leading to asymmetric removal, surface damage, and increased waste due to instability and uneven engagement of stripping tools.

Innovation Solution

A wire processing machine with an integrated stripping device that uses synchronously moving stripping tools and supporting elements to stabilize the flat material, ensuring precise engagement and minimizing surface damage, by feeding supporting elements alongside the stripping tools to maintain contact and control the stripping process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If stripping tools are fed into engagement with the insulation layer without additional support, then the stripping operation can be performed, but the flat material becomes unstable and the stripping is incomplete and asymmetric

Engineering Contradiction:

Improvestripping precisionVSAvoidmaterial stability

Core Design Contradiction:

Manufacturing precisionVSStability of the object's composition

Solution Approach 1:

Supporting elements are introduced as intermediary components between the stripping tools and the flat material. These supporting elements provide additional contact points that stabilize the flat material during the stripping operation, preventing instability and ensuring complete, symmetric stripping without interfering with the primary stripping function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If stripping tools are fed deeply into the insulation layer to ensure complete stripping, then the insulation is fully removed, but the carrier material surface becomes damaged

Engineering Contradiction:

Improvestripping completenessVSAvoidsurface damage

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

Supporting elements are fed synchronously with the stripping tools to establish contact with the flat material before the stripping tools engage. This preliminary positioning provides immediate support and defines the engagement depth, preventing the stripping tools from penetrating too deeply and damaging the carrier material surface while ensuring complete insulation removal.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If the stripping operation is performed without synchronous support, then the process is simpler, but material waste increases due to surface damage

Engineering Contradiction:

Improveprocess simplicityVSAvoidmaterial waste

Core Design Contradiction:

Device complexityVSLoss of substance

Solution Approach 1:

The supporting elements act as mediators that minimize material waste by preventing surface damage during stripping. Although they add components to the system, they ensure that the carrier material surface remains intact, thereby reducing waste and improving overall process efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method of producing shaped parts includes drawing insulated flat material with a draw-in device and processing in a wire processing machine to form the shaped part material; separating the shaped part from supplied insulated flat material by cutting, wherein before the shaped part is separated, part of the insulation layer is removed in a portion of the flat material; and synchronously with feeding stripping tools on each side of the flat material, feeding at least one supporting element toward the flat material.
