Solution Overview

Problem

Existing methods for terminating and processing cable arrangements are predominantly manual, leading to errors and damage of unintended constituent parts.

Innovation Solution

An apparatus comprising a positioning unit, an air stream supply device, and a processing unit with a cutting region, which positions and exposes the cable arrangement, uses an air stream to lift and separate constituent parts, and a cutting mechanism to remove them, reducing manual error and damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual methods are used for removing constituent parts of cable arrangements, then flexibility and adaptability are maintained, but susceptibility to error and damage to unintended constituent parts increases

Engineering Contradiction:

Improvesusceptibility to errorVSAvoidmanual operation

Core Design Contradiction:

ReliabilityVSExtent of automation

Solution Approach 1:

The patent replaces manual mechanical operations with an automated apparatus that uses a controlled air stream to lift and separate constituent parts, followed by a cutting mechanism. This substitution eliminates human error in the removal process while maintaining precision through automated control systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The apparatus enables the cable arrangement to be processed automatically without continuous manual intervention. The air stream supply device and cutting mechanism work in sequence to self-complete the removal task, reducing operator involvement and associated errors.

Inventive Principle:

Principle #25Self-service

2Reliability

If manual methods are used for exposing electrical conductor arrangements, then operational flexibility is preserved, but the risk of damaging unintended constituent parts increases

Engineering Contradiction:

Improvedamage to constituent partsVSAvoidmanual processing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The air stream acts as an intermediary between the operator and the constituent parts. Instead of direct manual contact that could cause damage, the air stream gently lifts and positions the parts for removal, reducing the risk of accidental damage while maintaining operational ease.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The apparatus segments the processing task into distinct phases: air stream lifting, separation, and cutting. This segmentation allows each phase to be optimized independently, ensuring that constituent parts are handled carefully during lifting and removed precisely during cutting, thereby reducing damage risk.

Inventive Principle:

Principle #1Segmentation

3Reliability

If automated apparatus is used for removing constituent parts, then susceptibility to error is reduced, but device complexity increases

Engineering Contradiction:

Improveerror susceptibilityVSAvoidapparatus structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The apparatus is designed with multi-functional components that perform multiple tasks. The air stream supply device not only lifts constituent parts but also positions them for cutting. The processing unit integrates both lifting and cutting functions, reducing the number of separate devices needed and thereby limiting the increase in overall complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the air stream supply device and cutting mechanism into a single integrated processing unit. This consolidation reduces the number of separate components and simplifies the overall apparatus structure while maintaining the reliability benefits of automation.

Inventive Principle:

Principle #5Merging (Combining)
