Rotating Ferrule Adapter for Secure Multi-Fiber Mating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic systems face challenges in securely connecting multi-fiber ferrules without complex connector components, as current methods are either insecure or require extensive reworking, and existing clips are not sturdy enough to mount ferrules to structures effectively.
Innovation Solution
A ferrule-to-ferrule adapter with a main body and engagement members that optically and mechanically mate multi-fiber ferrules, featuring rotatable or fixed spring latches to securely hold the ferrules in place, allowing for easy installation and cost-effective connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex connector components are used to hold multi-fiber ferrules, then the connection reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The adapter is divided into distinct functional segments: a body portion that provides structural support and alignment, and separate engagement members that provide secure retention. This segmentation allows each component to be optimized for its specific function while keeping the overall structure relatively simple.
Solution Approach 2:
The engagement members are designed to be received within recesses in the adapter body, creating a nested structure. The engagement members can rotate within the body's engagement member recesses, providing secure retention without requiring complex external connector components.
2Reliability
If extensive reworking of pig-tails and multi-fiber ferrules is performed to achieve connection, then the connection security is improved, but the manufacturing time and cost increase
Solution Approach 1:
The adapter is pre-configured with engagement members and alignment features during manufacturing. The body portion includes pre-formed recesses that receive the engagement members, and the engagement members are pre-positioned to automatically engage with the ferrules when inserted, eliminating the need for complex field reworking.
Solution Approach 2:
The adapter body acts as an intermediary component that facilitates the connection between two ferrules. It provides a standardized interface with engagement members that securely hold the ferrules in place, simplifying the connection process compared to direct ferrule-to-ferrule attachment methods.
3Device complexity
If simple resilient clips are used to clip ferrules together, then the device complexity is reduced, but the connection strength and mounting capability deteriorate
Solution Approach 1:
The engagement members are designed with rotational movement capability within the adapter body. This dynamic feature allows the engagement members to be inserted in a relaxed state and then rotated into a locked position, providing strong retention forces while maintaining a relatively simple overall structure.
Solution Approach 2:
The adapter combines multiple functions into a single integrated structure: the body portion provides structural support and alignment, while the engagement members provide secure retention. This merging of functions creates a stronger connection than simple clips while avoiding the complexity of separate connector components.

AI summary
An adapter for holding two multi-fiber ferrules in positions to mate with one another includes a main body, a opening extending through the main body configured to receive and optically and mechanically mate the two multi-fiber ferrules. Engagement members, which preferably rotate about an axis transverse to the opening, is disposed adjacent the opening on each side of the adapter to engage and hold the multi-fiber ferrules in the adapter.
