Solution Overview

Problem

Conventional optical transceivers require significant space in front of the face plate to accommodate external optical fibers due to the perpendicular alignment of optical receptacles, which can lead to increased stress on inner fibers and limited wiring space.

Innovation Solution

The optical transceiver housing features an optical receptacle with a diagonal cavity alignment, allowing the external connector to be inserted at a substantial angle, reducing stress on inner fibers through diagonal grooves and a unique assembly mechanism that secures the sleeve within the receptacle, and includes a rotating receptacle option for further space optimization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the optical receptacle cavity extends perpendicular to the face plate, then the external optical connector can be easily inserted and engaged, but it requires significant space in front of the face plate and increases stress on inner fibers

Engineering Contradiction:
Improveease of connector insertionVSAvoidspace in front of face plate
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The cavity axis is rotated from a perpendicular orientation (along the longitudinal axis) to a diagonal orientation relative to the face plate. This dimensional change in the cavity's spatial arrangement allows the external fiber to exit at a diagonal angle, directing it toward the side of the housing rather than extending straight out in front, thereby reducing the required space in front of the face plate while maintaining ease of connector insertion

Principle #17Another dimension (Dimensionality change)

2Device complexity

If the optical receptacle cavity extends perpendicular to the face plate, then the structural alignment is simplified, but it increases stress on the inner fiber and limits wiring space within the housing

Engineering Contradiction:
Improvestructural alignment complexityVSAvoidfiber stress resistance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The cavity is oriented diagonally rather than perpendicular to the face plate. This diagonal orientation changes the extraction direction of the external fiber, allowing it to exit toward the side of the housing. The inner fiber is routed through a diagonal groove that follows this new orientation, creating a more gradual stress distribution path and reducing concentrated stress on the fiber while providing adequate wiring space within the housing structure

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

Solution Approach 2:

The diagonal cavity orientation creates an asymmetric arrangement where the external fiber exits at an angle rather than symmetrically perpendicular to the face plate. This asymmetric configuration, combined with the diagonal groove routing, distributes mechanical stress more evenly along the fiber path and provides optimized wiring space within the housing, improving fiber reliability without significantly increasing structural alignment complexity

Inventive Principle:
Principle #4Asymmetry
