Solution Overview

Problem

Conventional fiber optic terminals designed for outdoor environments are bulky and unsuitable for indoor use, as they require robust connectors that are not needed in indoor settings, leading to a need for simplified terminals that can accommodate non-hardened fiber optic connectors for improved space efficiency and aesthetics.

Innovation Solution

The development of fiber optic terminals with flexible tabs and actuators that allow for quick and easy release of external connectors, enabling the use of non-hardened connectors and providing a scalable form-factor for various connector types, including LC and SC connectors, without the need for rotating fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hardened fiber optic connectors with rotating fasteners are used, then connection reliability in outdoor environments is improved, but device size and complexity increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the rotating fastener mechanism from the connector design, retaining only the essential latching trigger and latch components. This removes the complex bayonet or threaded coupling mechanisms while preserving the core function of secure connection and release through the latching trigger actuating the latch to disengage the connector body from the adapter.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the rotating mechanical fastening system (bayonet or threaded couplings) with a linear actuation system where the latching trigger moves in a straight line to actuate the latch. This substitution eliminates the need for rotational movement and complex fastener mechanisms, reducing device complexity while maintaining connection reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If hardened fiber optic connectors with rotating fasteners are used, then connection security is improved, but space requirements increase

Engineering Contradiction:
Improveconnection securityVSAvoidspace requirements
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent removes the bulky rotating fastener components from the connector design, keeping only the compact latching trigger and latch mechanism. This extraction of unnecessary components significantly reduces the volume occupied by the connector while preserving the essential security function through the latch engagement with the adapter.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a flexible tab component that works in conjunction with the latch mechanism. The flexible tab provides the necessary mechanical compliance and sealing function without requiring rigid, space-consuming structures, allowing for a more compact overall design that maintains connection security.

Inventive Principle:
Principle #30Flexible shells and thin films

3Volume of moving object

If simplified fiber optic terminals for indoor use are developed, then space efficiency is improved, but adaptability to different connector types decreases

Engineering Contradiction:
Improvespace efficiencyVSAvoidadaptability to connector types
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent designs the adapter with a universal latch mechanism that can accommodate different connector types (such as LC and SC connectors) through the standardized latching trigger interface. The flexible tab and latch configuration can work with various connector body styles, allowing a single adapter design to serve multiple connector types without sacrificing space efficiency.

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

Solution Approach 2:

The patent incorporates a dynamic flexible tab component that can adapt its position and configuration to accommodate different connector types. The flexibility of the tab allows it to comply with varying connector geometries while maintaining the latching function, providing adaptability without requiring multiple specialized adapter designs.

Inventive Principle:
Principle #15Dynamics

AI summary

Fiber optic terminals having one or more connector ports configured for receiving fiber optic connector having a latching trigger used as a connector securing/release mechanism connectors are disclosed. The fiber optic terminals comprise an actuator along with a flexible tab that are associated with the respective connector port of the shell of the fiber optic terminal. The actuator may translate to engage the flexible tab for engaging with the latching trigger of the fiber optic connector for allowing the release of the fiber optic connector from the connector port. An example of a fiber optic connector having a latching trigger used as a connector securing/release mechanism are LC connectors, but the terminal concepts may be used with other suitable connectors such as SC connectors having a latching trigger.
