Solution Overview

Problem

Manual application of adhesive to multiple strands of optical fibers for ribbonizing results in inconsistent alignment and bending, leading to difficulties in achieving accurate fusion during the fusion of ribbonized optical fibers.

Innovation Solution

An optical fiber ribbonizing adhesive applicator with a clamp sheet and horizontal moving means that fixes and aligns optical fibers vertically, applies adhesive evenly, and draws them horizontally in a straight line, using a sliding mechanism to ensure precise alignment and even adhesive distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adhesive application is used to ribbonize optical fibers, then the process is simple and quick, but the alignment precision and straightness of the ribbonized fibers deteriorate due to inconsistent extension and bending

Engineering Contradiction:

Improvesimplicity of adhesive applicationVSAvoidalignment precision of optical fibers

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

A clamp sheet is introduced as an intermediary tool between the manual application process and the optical fibers. The clamp sheet provides a structured framework with guide grooves that constrain and align multiple optical fibers during adhesive application, ensuring consistent spacing and straightness without requiring complex automated equipment.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The clamp sheet is designed to be self-aligning through its structural features including guide grooves and positioning elements. When the clamp sheet is placed on the optical fibers, the fibers automatically settle into the correct positions within the grooves, eliminating the need for precise manual positioning while maintaining high alignment precision.

Inventive Principle:

Principle #25Self-service

2Strength

If optical fibers are drawn while adhesive is applied longitudinally, then the adhesive bonds the fibers together, but the fibers bend and become misaligned due to differential extension

Engineering Contradiction:

Improvebonding strength of adhesiveVSAvoidstraightness of optical fibers

Core Design Contradiction:

StrengthVSShape

Solution Approach 1:

The clamp sheet is positioned and secured on the optical fibers before adhesive application begins. This preliminary action establishes fixed reference points and constraints that prevent differential extension and bending during the subsequent adhesive application and drawing processes, maintaining fiber straightness while enabling effective bonding.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The clamp sheet applies localized constraints at specific positions along the optical fibers through its guide grooves and clamping elements. This localized quality control ensures that only the necessary areas are constrained for alignment, while allowing natural fiber extension in controlled manner, preventing bending without over-constraining the entire fiber length.

Inventive Principle:

Principle #3Local quality

AI summary

Disclosed is an optical fiber ribbonizing adhesive applicator, and more specifically, an optical fiber ribbonizing adhesive applicator configured to ribbonize multiple optical fibers into a single one before a plurality of individual optical fibers are fused together, by enabling the multiple strands of optical fibers to which an adhesive has been applied to be ribbonized in a straight-line shape in a longitudinal direction without being bent, and further an adhesive storage tray is provided to enable an excess adhesive to be evenly applied to the optical fibers.
