Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-density fiber optic connectors in data centers require numerous components, leading to increased costs and complexity, which can be reduced by simplifying the connector design without compromising functionality.
Innovation Solution
The development of a low-profile, reduced-sized behind-the-wall connector with a resilient latch and ferrule flange configuration, which eliminates unnecessary components like the extender cap and spring, while maintaining proper alignment and connection reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional fiber optic connectors are used with multiple components (extender cap, spring, etc.), then connection reliability is maintained, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent removes unnecessary components from the traditional connector design, specifically eliminating the extender cap and spring while retaining only the essential latch mechanism. This extraction of non-essential parts reduces component count and manufacturing complexity while maintaining the core functionality of secure connection and reliable release
Solution Approach 2:
The patent integrates the latch mechanism directly into the connector housing structure, merging what were previously separate components into a unified design. The latch is formed as an integrated feature of the housing rather than being a separate part, reducing the total number of components while maintaining the release functionality
2Volume of moving object
If connector size is reduced for high-density applications, then space efficiency improves, but alignment precision and connection reliability may deteriorate
Solution Approach 1:
The patent applies local quality by providing precise alignment features (alignment pins, guide surfaces) only at the critical interfacing points of the connector, while the overall connector size is minimized. The alignment precision is concentrated where needed at the mating interface rather than requiring precision throughout the entire connector structure
Solution Approach 2:
The patent employs a compact latch mechanism that nests within the connector housing structure. The latch features are integrated into the housing geometry, allowing the release mechanism to be contained within the minimal connector volume without requiring additional external space
3Device complexity
If components are eliminated to reduce cost, then manufacturing simplicity improves, but connection reliability may worsen
Solution Approach 1:
The patent employs a resilient latch mechanism that automatically engages and disengages without requiring additional components or complex control systems. The latch's elasticity provides automatic return to the engaged position after release, and the design ensures reliable connection through inherent mechanical properties rather than additional control components
Solution Approach 2:
The patent utilizes the elastic properties of the latch material as a key parameter, where the resilient nature of the latch provides both the engagement force and the release mechanism. By changing the physical state of the latch material from rigid to elastic, the design achieves reliable connection and release functionality without requiring separate actuating components

Function Achieved in This Case
This design reduces the number of components and manufacturing costs while enhancing the reliability and ease of connector removal, making it suitable for high-density data center applications.
Implementation Method 1
The connector has a release or latch with a recess that secures the connector in the adapter via an opening in the adapter housing. The connector release is integrated at one end of the connector housing, and extends beyond a second end.

AI summary
A behind-the-wall optical connector an outer housing configured to be inserted into an adapter with a corresponding inner surface, a ferrule included in an annular collar to mate with a corresponding projection at an adapter opening, and a latch attached to one side of housing configured to lock the connecter into an adapter opening. The latch is further configured with a locking channel and guide to accept a pull tab with a catch at one end, the pull tab releases the connector from the adapter opening when the tab is pulled rearward or away from the adapter.
