Solution Overview

Problem

The installation of multiple optical cables in a parallel state becomes complicated and labor-intensive, especially when the number of cables is large, leading to reduced workability.

Innovation Solution

A holding jig designed to grip multiple optical cables in parallel, featuring gripping portions that extend along the cable axis and are coupled side by side, with features like arc-shaped inner circumferences and protrusions to maintain cable alignment and stability during installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple optical cables are installed individually without a holding jig, then each cable can be installed independently, but the installation process becomes complicated and labor-intensive with reduced workability

Engineering Contradiction:
ImproveworkabilityVSAvoidinstallation process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple cable gripping functions into a single holding jig structure. The holding jig integrates multiple gripping portions that can simultaneously hold multiple optical cables, merging what would otherwise be separate handling operations into one unified tool, thereby improving ease of operation while managing complexity

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If multiple optical cables are installed without a holding jig to maintain parallel alignment, then installation may be simpler, but maintaining parallel cable arrangements becomes difficult and time-consuming

Engineering Contradiction:
Improveparallel cable arrangementVSAvoidtime for alignment
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The holding jig is designed with gripping portions that preliminarily establish and maintain the parallel arrangement of optical cables during installation. By incorporating alignment features and parallel gripping structures into the jig itself, the parallel configuration is maintained automatically throughout the installation process, eliminating the need for time-consuming post-installation alignment work

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If a holding jig with multiple gripping portions is used to hold multiple optical cables, then parallel cable arrangement is maintained easily, but the device structure becomes more complex

Engineering Contradiction:
Improveease of maintaining parallel arrangementVSAvoidholding jig structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The holding jig is segmented into multiple independent gripping portions, each capable of holding one optical cable. This segmentation allows the jig to maintain parallel cable arrangements through modular design, where each gripping portion can be positioned and adjusted independently, simplifying the overall structure while achieving the desired functionality

Inventive Principle:
Principle #1Segmentation

AI summary

A holding jig is attachable to a plurality of optical cables to hold the plurality of optical cables in parallel to each other. The holding jig includes a plurality of gripping portions. Each of the plurality of gripping portions is configured to grip a sheath of an optical cable. Each of the plurality of gripping portions includes a first end portion and a second end portion and extends in a first direction. The first direction is, in a state in which the sheath of the optical cable is gripped, a direction from the first end portion toward the second end portion which is along an axis of the optical cable and also a direction parallel to the axis of the optical cable. The plurality of gripping portions are coupled side by side so as to grip the plurality of optical cables arranged in parallel.
