Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical fiber coupling devices require time-consuming and inconvenient rotation of a coupling sleeve for connecting and disconnecting optical fiber sockets and plugs, making the operation inefficient.
Innovation Solution
The optical fiber plug and socket designs include a coupling unit with a movable coupling cover and a resilient coupling ring that locks and releases the connection, allowing swift connection and disconnection by moving the coupling cover between locked and released positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coupling sleeve with threads is used to connect the optical fiber socket and plug, then the connection is firm and stable, but the operation becomes time-consuming and inconvenient due to rotation requirement
Solution Approach 1:
The patent replaces the traditional threaded mechanical coupling system with a snap-fit mechanism. The coupling ring with elastic deformation capability engages with the connecting groove through a snap-action, eliminating the need for rotational threading operations. This substitution maintains connection reliability while dramatically improving ease of operation.
Solution Approach 2:
The coupling ring is designed as a dynamic elastic component that can deform during the connection process. When the plug is inserted, the coupling ring elastically deforms to pass through the connecting groove, then snaps into place to lock the connection. This dynamic behavior enables automatic locking without manual rotation, resolving the contradiction between stability and convenience.
2Reliability
If a coupling sleeve is used to firmly connect the optical fiber socket and plug, then the connection is secure, but the disconnection process becomes time-consuming and inconvenient
Solution Approach 1:
The patent replaces the threaded mechanical system with a snap-fit mechanism that enables rapid one-handed operation. The elastic coupling ring allows both connection and disconnection to be performed quickly without tools or complex maneuvers, significantly reducing time loss while maintaining secure connection during use.
Solution Approach 2:
The coupling ring's elastic properties enable the connection mechanism to be self-actuating. During insertion, the ring automatically deforms and locks into the groove without user intervention. For disconnection, the ring's elasticity allows it to be easily released with a simple pulling motion, making the system self-service oriented and eliminating time-consuming manual operations.

AI summary
An optical fiber plug adapted to be connected to an optical fiber socket and a first optical fiber cable includes a plug sleeve unit, a plug unit, a plug guiding unit, and a coupling unit. The coupling unit includes a coupling seat, a coupling ring, and a coupling cover movable between a locked position and a released position. When the coupling cover is at the locked position, the optical fiber plug is locked to the optical fiber socket by the coupling ring. When the coupling cover is moved from the locked position to the released position, the coupling ring is urged resiliently by the coupling cover to release the optical fiber plug, thereby permitting separation of the optical fiber plug from the optical fiber socket.
