Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional fiber distribution hubs in passive optical networks rely on manually maintained records for tracking available ports, leading to high likelihood of human error, inaccurate data, and delayed detection of disconnected termination units, which can cause premises to be accidentally disconnected for hours or days.

Innovation Solution

A system that automatically updates fiber distribution records in real-time by detecting when a termination unit disconnects and reallocates it to another port, using processors to determine bandwidth thresholds and update port availability records.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manually maintained records are used to track available ports, then device complexity is reduced, but reliability deteriorates due to human error and inaccurate data

Engineering Contradiction:

Improverecordkeeping system complexityVSAvoidport availability data accuracy

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system automatically monitors its own port status and updates records without human intervention. The fiber distribution hub self-updates the database when ports are connected or disconnected, eliminating reliance on manual recordkeeping while maintaining system simplicity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors port status and provides real-time feedback to update the database. When a port is connected or disconnected, the system detects this change and automatically updates the record, ensuring data accuracy through continuous verification.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If manually maintained records are used, then ease of operation is improved, but loss of time increases due to delayed detection of disconnected termination units

Engineering Contradiction:

Improverecordkeeping operationVSAvoidtime to detect disconnection

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system continuously monitors port status without interruption. The automatic detection mechanism operates constantly to identify when termination units are disconnected, eliminating the time delay inherent in manual checking while keeping the system easy to operate.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system automatically detects and reports disconnected termination units without requiring manual intervention. This self-monitoring capability reduces the time to detect disconnections from hours or days to near-real-time while maintaining operational simplicity.

Inventive Principle:

Principle #25Self-service

3Reliability

If computerized recordkeeping is implemented, then reliability is improved, but device complexity increases due to multiple views and systems

Engineering Contradiction:

Improverecord accuracyVSAvoidrecordkeeping system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system combines port status monitoring, database management, and user interface functions into a single integrated system. By merging these previously separate components, the system maintains high reliability through automated tracking while reducing complexity by eliminating the need to switch between multiple views or systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fiber distribution hub performs multiple functions including port monitoring, data recording, and user interface provision within a single system. This multi-functionality approach improves reliability by centralizing data management while reducing the complexity of having separate specialized systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Productivity

If real-time updating is implemented, then productivity is improved, but use of energy increases due to continuous monitoring

Engineering Contradiction:

Improveerror correction speedVSAvoidenergy for continuous monitoring

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The system uses periodic polling or event-triggered updates rather than continuous monitoring. The fiber distribution hub checks port status at regular intervals or only when changes occur, maintaining high productivity for error detection while reducing energy consumption compared to truly continuous monitoring.

Inventive Principle:

Principle #19Periodic action

AI summary

Systems and methods for tracking fiber port availability in a fiber distribution hub are presented. An exemplary method may include: determining that a connected termination unit associated with a fiber distribution hub uses more than a predetermined threshold value of bandwidth, the connected termination unit having an association with a port of a plurality of candidate ports included in the fiber distribution hub; responsive to the determining, transmitting an indication to transfer the connected termination unit to another port of the plurality of candidate ports; and updating a fiber distribution record representative of port availability in the fiber distribution hub to indicate an updated association between the connected termination unit and the another port.
