Solution Overview

Problem

SFP optical connectors are susceptible to dust contamination, which can lead to signal degradation and system failures, necessitating effective protection mechanisms to prevent dust exposure.

Innovation Solution

A bale-clasp cover mechanism with integrated dual dust covers and a U-shaped arm assembly that protects the optical transceiver connectors from contamination and ensures secure attachment and detachment, while also preventing light leakage and dust ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If dust caps are used to cover the SFP optical connector when not in use, then protection from dust contamination is improved, but device complexity increases due to additional components and operations required

Engineering Contradiction:
Improvedust contaminationVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines the dust cap protection function with the bale-clasp locking mechanism into a single integrated structure. The cover assembly is merged with the clasp handle and spring mechanism, eliminating the need for separate dust caps while maintaining protection functionality. This resolves the contradiction by reducing device complexity through consolidation of functions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bale-clasp mechanism serves multiple functions simultaneously: it locks the optical connector in place, provides dust protection through integrated covers, and enables secure attachment/detachment operations. This multi-functionality eliminates the need for separate dust cap components, resolving the contradiction between protection and complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If manual dust cap application is required, then protection from dust is improved, but ease of operation deteriorates due to additional manual steps

Engineering Contradiction:
Improvedust contaminationVSAvoidoperation convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The dust protection covers are integrated into the bale-clasp mechanism itself, so that the same component that provides locking also provides protection. Users interact with a single mechanism rather than separate dust caps, improving ease of operation while maintaining protection.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The spring-loaded covers automatically engage and disengage based on the insertion/removal of the optical connector, eliminating the need for manual dust cap application. The system serves itself by automatically providing protection during operations.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If separate dust caps are used, then protection from dust is improved, but productivity deteriorates due to additional time for cap application and removal

Engineering Contradiction:
Improvedust contaminationVSAvoidoperation efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

By merging the dust protection function into the locking mechanism, the patent eliminates separate cap application and removal steps. The single bale-clasp operation simultaneously provides both locking and protection, improving productivity by reducing the number of operations required.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated covers automatically follow the insertion/removal of connectors, providing protection without requiring separate manual operations. This self-service mechanism eliminates time-consuming cap handling steps, improving operational efficiency.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If the optical connector is exposed, then ease of operation is improved for connection, but reliability deteriorates due to dust exposure risk

Engineering Contradiction:
Improveconnection accessibilityVSAvoidsignal quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The integrated cover mechanism ensures that protection is automatically provided when the connector is not in use, while allowing easy access during connection operations. The same structure that enables connection also provides protection, resolving the contradiction between accessibility and reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The spring-loaded covers are positioned to automatically engage and protect the connector before any dust contamination can occur. This preliminary protection action prevents dust exposure while maintaining easy access during intended connection operations.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

The present invention relates to a bale-clasp cover system for a single or duplex lucent connector (LC) pluggable optical transceiver (10) comprising a bale-clasp handle (11), first and second covers (12), a U-shaped arm assembly (13) connected to a said handle (11) and adapted to pivotally release the transceiver (10) by activating release arm (15), and protruding marks (17) in the optical transceiver (10) top surface aligned with the LC connections. Said bale-clasp cover mechanism is adapted to equip a single or duplex LC pluggable optical transceiver (10) and to provide a quadruple mechanism of preventing light leakage, preventing the ingress of dust or other contaminants into the LC plug socket (18), allow the removal of the SFP optical transceiver (10) from the housing (14) and indicate the correct position for connecting the single LC (16) or LC duplex (20) optical connectors.
