Solution Overview

Problem

Conventional multiports for optical connections are bulky and inflexible, occupying excessive space and requiring complex coupling mechanisms, which limits their deployment in tight spaces and raises aesthetic and organizational concerns.

Innovation Solution

The development of multiports with integrated connection ports and securing features that allow direct insertion of fiber optic connectors, eliminating the need for threaded or bayonet couplings, thereby reducing footprint and enabling compact, dense, and organized arrangements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional threaded or bayonet coupling mechanisms are used for fiber optic connectors, then connection reliability is improved, but device complexity and footprint increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidcoupling mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the threaded or bayonet coupling mechanisms from the fiber optic connector system. The connector housing directly receives and secures the fiber optic connector without requiring separate coupling components, thereby reducing device complexity while maintaining connection reliability through direct integration.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the functions of the connector housing and the coupling mechanism into a single integrated structure. The housing itself provides both the structural support and the securing function, eliminating the need for separate coupling components and reducing overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple receptacles are mounted on a housing for hardened connectors, then optical connection capability is improved, but housing volume increases

Engineering Contradiction:
Improveoptical connection capabilityVSAvoidhousing volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent implements a nested arrangement where fiber optic connectors are received directly within the housing structure in a compact, space-efficient manner. The connectors are integrated into the housing volume rather than requiring external mounting, allowing multiple connections within a reduced overall housing volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent optimizes the spatial arrangement of multiple receptacles by utilizing three-dimensional space more efficiently within the housing. Rather than linear or surface-mounted arrangements that increase footprint, the design employs vertical or multi-level positioning to accommodate multiple connectors within a compact volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If conventional multiport housings are designed for outdoor deployments, then environmental durability is improved, but flexibility for mounting and space utilization worsens

Engineering Contradiction:
Improveenvironmental durabilityVSAvoidmounting flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent incorporates dynamic or adjustable mounting features into the housing design, allowing the multiport to be adapted to various mounting configurations (wall-mounted, pedestal-mounted, rack-mounted) while maintaining the rugged outdoor enclosure. The housing can be configured for different installation environments without compromising environmental durability.

Inventive Principle:
Principle #15Dynamics
