Preformed Fiber Optic Circuits for Automated Termination

Solution Overview

Problem

The installation and serviceability of fiber optic networks in dense environments are hindered by the complexity of fiber positioning and the need for skilled labor in terminating optical fibers to connectors.

Innovation Solution

Preformed fiber optic circuits are used, where fibers are arranged in a predetermined orientation and supported by flexible foil with silicone coating, allowing for automated termination and reduced manual handling, thus optimizing fiber bend radius and equipment dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual fiber positioning and termination is used, then precise fiber alignment can be achieved, but installation complexity and labor requirements increase significantly

Engineering Contradiction:

Improvefiber alignment precisionVSAvoidinstallation complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-arranging fibers in a predetermined orientation and layout before termination. The fibers are positioned and secured to the substrate in advance, creating a preformed optical circuit that maintains precise alignment throughout installation. This eliminates the need for complex manual positioning during installation while preserving alignment precision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses an intermediary substrate (such as a flexible foil or rigid board) that serves as a mediator between the fibers and the final installation environment. The substrate provides a structured platform with predetermined fiber positions, acting as an intermediary that maintains fiber alignment while simplifying the overall installation process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If skilled labor is used for fiber termination, then high-quality connections can be achieved, but labor costs and installation time increase

Engineering Contradiction:

Improveconnection qualityVSAvoidinstallation speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-arranging fibers in a predetermined orientation and layout before termination. The fibers are positioned and secured to the substrate in advance, creating a preformed optical circuit that maintains precise alignment throughout installation. This eliminates the need for complex manual positioning during installation while preserving alignment precision.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If fibers are left flexible and unpositioned, then ease of handling is improved, but fiber bend radius control and positioning precision deteriorate

Engineering Contradiction:

Improvefiber handling easeVSAvoidfiber positioning precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies flexible shells and thin films by using a flexible foil substrate to support and position the optical fibers. The flexible foil provides structural support that maintains predetermined fiber positions and orientations while still allowing the entire assembly to be flexible and easy to handle during installation. This resolves the contradiction by providing positioning precision through the foil structure while maintaining handling ease through the flexible nature of the substrate.

Inventive Principle:

Principle #30Flexible shells and thin films
