Solution Overview

Problem

Existing tools are cumbersome and time-consuming when introducing a fibre optic cable into a power cord assembly device, making the process difficult and prone to damage.

Innovation Solution

A tool with guide means and support means arranged in a frame to widen the slit of the extruded profiled body, allowing easy and safe introduction of the fibre optic cable, using guide members and friction-reducing elements to facilitate movement and prevent damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a prior art tool is used to introduce a fibre optic cable into the power cord assembly device, then the operation can be performed, but it is cumbersome and time-consuming

Engineering Contradiction:
Improvespeed of introducing fibre optic cableVSAvoidease of introducing fibre optic cable
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent introduces a specialized tool as an intermediary device between the fibre optic cable and the power cord assembly device. This tool includes guide means with guide members that facilitate the cable's passage through the slit, and support means that stabilize the profiled body during the operation. The intermediary tool simplifies the complex manual operation by providing structured guidance and support, making the process easier and faster to perform.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the slit of the profiled body is widened to allow fibre optic cable introduction, then accessibility to the chamber is improved, but the structural integrity of the profiled body may be compromised

Engineering Contradiction:
Improveaccessibility to chamberVSAvoidstructural integrity of profiled body
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The support means are positioned to bear against specific portions of the profiled body walls before and during the widening of the slit. This preliminary positioning of support elements prevents excessive deformation or damage to the profiled body structure while the guide means widen the slit sufficiently for cable introduction. The support means maintain structural integrity throughout the opening process.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If manual introduction of fibre optic cable is performed without specialized tools, then device complexity is reduced, but the risk of fibre optic cable damage increases

Engineering Contradiction:
Improvecomplexity of introduction toolVSAvoidprotection of fibre optic cable
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The guide means act as an intermediary structure that protects the fibre optic cable during introduction. The guide members provide a controlled pathway through the slit, preventing direct contact between the cable and the sharp edges of the slit opening. This intermediary guidance structure minimizes mechanical stress and damage risk to the delicate fibre optic cable while maintaining relatively simple device complexity.

Principle #24Intermediary (Mediator)
