Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic cable connection systems face challenges in providing high fiber optic circuit densities and secure connections, especially in outdoor environments, where mechanical and environmental stresses are prevalent.
Innovation Solution
A dual fastening arrangement and tapered interface in a fiber optic adapter design, combined with a snap-fit latch mechanism and coupling nut, ensure secure and high-density connections by providing a robust mechanical and optical coupling system that can withstand environmental stresses and high pull-out forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single fastening mechanism is used in the fiber optic adapter, then the device complexity is reduced, but the reliability of the connection under environmental stresses and pull-out forces deteriorates
Solution Approach 1:
The fastening arrangement is segmented into two distinct mechanisms: a snap-fit latch mechanism for initial connection and retention, and a coupling nut for threaded securing. This segmentation allows each mechanism to be optimized for its specific function while together providing enhanced overall reliability against environmental stresses and pull-out forces
Solution Approach 2:
The dual fastening arrangement provides beforehand cushioning by having redundant securing mechanisms in place before environmental stresses or pull-out forces are applied. The snap-fit latch and coupling nut work together to pre-establish a robust connection that can withstand anticipated environmental conditions and mechanical loads
2Strength
If fiber optic connectors are secured with a robust mechanical fastening system, then the strength of the connection is improved, but the ease of operation for installation and removal deteriorates
Solution Approach 1:
The snap-fit latch mechanism incorporates dynamic elements that allow for easy engagement and disengagement. The latch can be quickly actuated to secure the connector firmly (providing high pull-out resistance) or released to allow removal, enabling the system to transition between strongly secured and easily operable states
3Manufacturing precision
If the adapter uses a tapered interface to complement the connector interface, then the manufacturing precision of the connection is improved, but the device complexity increases
Solution Approach 1:
The tapered interface employs a conical (curved) geometry rather than a cylindrical straight interface. This tapered configuration provides self-aligning properties that guide the ferrule into proper alignment during insertion, improving manufacturing precision and connection reliability while adding minimal structural complexity to the adapter
