Solution Overview

Problem

Current optical connectors with alignment sleeves require complex and time-consuming processes to access and remove ferrules for cleaning or replacement, especially when the number of sockets is large or small, as existing systems often necessitate separate removal of sleeves and lack efficient locking mechanisms.

Innovation Solution

A one-piece alignment socket holder with a push-pull type locking system allows for simultaneous removal and reassembly of multiple alignment sleeves without additional tools, featuring a locking mechanism that ensures precise alignment and easy handling, and can be exchanged if necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If individual socket mounting systems or screwed alignment sockets are used, then precise alignment is achieved, but the process to access and remove ferrules becomes complex and time-consuming

Engineering Contradiction:
Improvealignment precisionVSAvoidferrule access ease
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent combines multiple alignment sockets into a single integrated holder that encapsulates all alignment bushings in one piece. This merging allows all sockets to be removed and reinstalled simultaneously as a single unit, eliminating the need for individual removal operations while maintaining precise alignment through the integrated structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention segments the connector system into distinct functional modules: a removable alignment socket holder containing all alignment bushings, and the main connector body with ferrules. This segmentation allows the alignment component to be easily separated and accessed as a complete unit, simplifying maintenance operations.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If alignment bushings remain on ferrules after protection removal, then alignment is maintained, but additional tools and operations are required to remove bushings

Engineering Contradiction:
Improvealignment precisionVSAvoiddisassembly complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges all alignment bushings into a single integrated holder assembly that moves as one unit. This eliminates the need for individual bushing removal operations and additional specialized tools, as the entire alignment system can be accessed by removing the single holder from the connector body.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention extracts the alignment socket holder as a separate, removable component from the main connector assembly. This extraction allows the alignment system to be easily removed and accessed without disassembling the entire connector, reducing the complexity of maintenance operations.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If a locking system is integrated into the alignment socket holder, then controlled removal is prevented during disconnection, but the locking mechanism adds structural complexity

Engineering Contradiction:
Improveconnection reliabilityVSAvoidholder structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a self-locking mechanism where the alignment socket holder automatically engages with the connector body through complementary geometric features. The holder's own structure provides the locking function through shaped engagement surfaces that naturally lock into place during assembly, eliminating the need for separate locking components.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention uses asymmetric geometric features on the holder and connector body that create a directional locking mechanism. The shaped engagement surfaces are designed with specific orientations that allow easy insertion in one direction while preventing accidental removal, providing reliable locking through asymmetric geometry rather than complex mechanical locks.

Inventive Principle:
Principle #4Asymmetry
