Solution Overview

Problem

Existing optical waveguide distribution devices face difficulties in safely transferring loose optical waveguides between adjacent splice cassettes without risking damage.

Innovation Solution

An optical waveguide transfer device, formed by two T-shaped guide elements, is positioned between adjacent splice cassette holders to protect and transfer loose optical waveguides, maintaining permissible minimum bending radii by guiding them through T-shaped optical waveguide guide elements that complement the existing guide channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If loose optical waveguides are transferred directly between adjacent splice cassette stacks without protection, then the transfer process is simple, but the optical waveguides are at risk of damage

Engineering Contradiction:

Improveprotection of loose optical waveguidesVSAvoidstructure of distribution device

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an optical waveguide transfer device as an intermediary element positioned between adjacent splice cassette holders. This transfer device includes guide channels that receive and protect loose optical waveguides during transfer, preventing direct exposure to damage risks while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The transfer device incorporates protective guide channels that act as flexible pathways for the optical waveguides. These channels provide physical protection similar to flexible sheathing, allowing the waveguides to be guided safely through the transfer path while maintaining bend radius requirements.

Inventive Principle:

Principle #30Flexible shells and thin films

2Ease of operation

If optical waveguides are transferred without maintaining minimum bending radii, then the transfer is easier, but the optical waveguides may be damaged

Engineering Contradiction:

Improvetransfer processVSAvoidintegrity of optical waveguides

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The guide channels of the transfer device are designed with specific curvature radii that match or exceed the minimum bending radius requirements of the optical waveguides. This ensures that waveguides can be transferred easily through the curved paths without risking damage from excessive bending, combining ease of operation with reliability.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Area of stationary object

If splice cassette holders are positioned close together for compact design, then space is saved, but loose optical waveguides cannot be safely transferred between them

Engineering Contradiction:

Improvespace between splice cassette holdersVSAvoidsafe transfer of optical waveguides

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The transfer device utilizes the third dimension (depth/height) by positioning guide channels above or below the plane of the splice cassette holders. This allows optical waveguides to be transferred between closely spaced holders by routing them through vertical or angled paths, maintaining compact horizontal spacing while ensuring safe transfer through protected channels.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
