Rotatable Boot Optical Connector for Easy Polarity Reversal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical connectors, particularly LC duplex connectors, are complex, require multiple components, and have limited functionality for reversing polarity, making them inefficient for high-density data center applications.
Innovation Solution
An optical connector design featuring a rotatable boot and outer housing that allows for relative rotation and axial movement, enabling easy detachment and polarity reversal by transitioning between locked and unlocked positions, simplifying the process with fewer components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional LC duplex connector designs are used with multiple components for latching and polarity reversal, then the connector can achieve basic functionality, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The boot and outer housing are merged into a single integrated component that performs multiple functions: strain relief, latching arm actuation, and polarity reversal. This consolidation eliminates the need for separate components to perform these functions, directly reducing device complexity while maintaining ease of operation through the unified rotational mechanism.
Solution Approach 2:
The outer housing is designed to serve multiple purposes: it provides structural support, acts as a lever to depress latching arms for detachment, and enables polarity reversal through rotation. This multi-functionality allows a single component to replace what would traditionally require multiple specialized parts, resolving the contradiction between simplicity and functionality.
2Ease of operation
If a rotatable boot design is implemented to enable polarity reversal and detachment, then ease of operation improves, but the manufacturing complexity increases
Solution Approach 1:
The boot is designed with rotational capability around the longitudinal axis, transforming from a static component to a dynamic one that can assume different positions (locked and unlocked). This dynamic feature enables polarity reversal and easy detachment while the integrated design with the outer housing ensures that the manufacturing process remains streamlined, avoiding the need for complex assembly of multiple moving parts.
3Adaptability or versatility
If the boot and outer housing are designed to rotate relative to each other, then functionality for detachment and polarity reversal is improved, but device complexity increases
Solution Approach 1:
The boot is nested within the outer housing, with the boot's rotational movement occurring within the confines of the outer housing structure. This nesting arrangement allows the rotational mechanism to be compact and integrated, providing versatile functionality for detachment and polarity reversal without adding significant structural complexity to the overall device.

AI summary
An optical connector includes a connector sub-assembly, an inner housing that receives a rear portion of the connector sub-assembly, a boot extending from the inner housing, and an outer housing coupled to the boot. The outer housing and the boot are configured to allow relative rotation about a longitudinal axis of the optical connector but can move together along the longitudinal axis. The boot can be rotated relative to the inner housing between a locked position in which the outer housing is prevented from moving axially and depressing the end portion of a latch arm of the connector sub-assembly, and an unlocked position in which the outer housing can move axially to depress the end portion of the latch arm.
