Solution Overview

Problem

Conventional multiports for optical connections are bulky and inflexible, occupying excessive space, requiring separate threaded or bayonet couplings, and posing organizational and aesthetic challenges in limited deployment environments.

Innovation Solution

The development of multiports with compact form-factors and integrated securing features that allow direct insertion of fiber optic connectors, eliminating the need for bulky couplings and enabling dense, organized arrays of connection ports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional multiports use separate threaded or bayonet couplings for securing connectors, then reliable optical connections are achieved, but the device becomes bulky and occupies excessive space

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmultiport housing volume
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent integrates the coupling mechanism directly into the connection port structure, merging the previously separate coupling components with the port housing. This integration eliminates the need for external threaded or bayonet couplings, thereby reducing overall device volume while maintaining connection reliability through the built-in securing features.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling features are nested within the connection port structure itself, with securing elements positioned inside the port housing rather than as external attachments. This nesting approach allows the coupling mechanism to occupy minimal space within the existing port volume, reducing the overall multiport footprint while ensuring secure connector attachment.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If multiple separate receptacles are attached to the housing for hardened connectors, then optical connection capability is provided, but the housing becomes excessively bulky and inflexible

Engineering Contradiction:
Improveoptical connection capabilityVSAvoidhousing shape flexibility
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The connection port structure is designed to universally accommodate different connector types directly through integrated securing features, eliminating the need for separate specialized receptacles for hardened connectors. This multi-functional design allows the same port structure to serve multiple connection purposes while maintaining housing compactness and shape flexibility.

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

Solution Approach 2:

The patent combines the functions of separate receptacles and coupling mechanisms into a single integrated connection port structure. By merging these previously distinct components, the housing maintains its structural integrity and flexibility while providing robust optical connection capabilities through the unified port design.

Inventive Principle:
Principle #5Merging (Combining)

3Volume of stationary object

If connection ports are arranged in dense arrays, then space requirements are reduced, but organizational and aesthetic challenges increase in limited deployment environments

Engineering Contradiction:
Improvespace occupancyVSAvoidport organization
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The patent implements distinct securing feature designs for different port types (e.g., different actuation mechanisms or visual indicators for various connector positions), allowing operators to quickly identify and access specific ports. This local differentiation within the dense array maintains ease of operation and organization while achieving compact space occupancy through high port density.

Inventive Principle:
Principle #3Local quality
