Solution Overview

Problem

Existing fiber optic connectors lack versatility in compatibility with different styles or types of fiber optic connectors or adapters, and there is a need for secure and reliable assembly features to ensure proper connection and environmental sealing.

Innovation Solution

A system for making fiber optic connectors that allows pre-terminated cables to be configured with various shrouds, housings, and fasteners, including turn-to-engage fasteners and snap-fit mechanisms, with retention arrangements and boot configurations for strain relief and secure assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a pre-terminated fiber optic cable is made compatible with multiple connector styles through selective mounting of different shrouds and outer assemblies, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvecompatibility with different connector stylesVSAvoidsystem assembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector core assembly is designed as a universal base that can accommodate multiple types of outer assemblies (shrouds, housings, fasteners) through standardized mounting interfaces. This allows a single pre-terminated cable to be configured for different connector styles (SC, LC, ST, etc.) by simply changing the outer assembly rather than redesigning the entire connector

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fiber optic connector is divided into separable components: a permanent connector core assembly and interchangeable outer assemblies. This segmentation allows the core (containing the terminated fiber) to remain fixed while different outer assemblies are mounted selectively to provide compatibility with various connector styles and environmental requirements

Inventive Principle:

Principle #1Segmentation

2Reliability

If robust fastening arrangements and hardened assemblies are used for ruggedized connectors, then reliability is improved, but ease of manufacture deteriorates

Engineering Contradiction:

Improveconnection securityVSAvoidassembly difficulty

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The connector core assembly is pre-terminated with the fiber optic cable in a controlled manufacturing environment, establishing secure mechanical and optical connections before field deployment. This preliminary action ensures reliability while simplifying field installation, as only the outer assembly needs to be mounted rather than performing complex termination procedures

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The connector core assembly serves as an intermediary between the fiber optic cable and the various outer assemblies. It provides standardized mounting interfaces that simplify the attachment of different outer assemblies while maintaining secure, reliable connections through pre-configured mechanical fastening arrangements

Inventive Principle:

Principle #24Intermediary (Mediator)
