Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Field-installable optical fiber connectors are limited by fixed dimensions in the boot's through hole, allowing only specific optical fiber sizes to be secured, restricting adaptability to different fiber types.
Innovation Solution
The optical fiber connector design includes a housing with a flexible fixing assembly and a rotatable covering member that engages with a stepped shape to securely clamp optical fibers of varying sizes, utilizing a fiber ferrule, elastic member, and clamping assembly to tighten Kevlar lines between wrapping sleeves, allowing different optical fiber cable diameters to be accommodated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the boot has fixed dimensions in the through hole, then the structure is simple and easy to manufacture, but the adaptability to different optical fiber sizes is limited
Solution Approach 1:
The boot transitions from a rigid fixed-dimension structure to a flexible structure that can dynamically adapt its through hole dimensions. The boot material is designed to be deformable, allowing it to stretch and conform to different optical fiber cable diameters, enabling a single boot design to accommodate multiple fiber sizes without increasing structural complexity
Solution Approach 2:
The through hole dimensions of the boot are changed from fixed parameters to variable parameters. By making the boot material flexible and deformable, the physical parameters (dimensions) of the through hole can be adjusted to match different optical fiber sizes, thereby improving adaptability while maintaining simple manufacturing processes
2Strength
If the optical fiber cable is tightly clamped between the inner and outer screw thread portions, then the clamping force is strong, but the ease of assembly and disassembly is reduced
Solution Approach 1:
The screw thread connection transitions from a permanently tight fixed state to a dynamic state where the clamping force can be adjusted. By allowing the boot and housing to be screwed together and apart, the clamping force on the Kevlar lines can be applied during assembly and released during disassembly, maintaining strong clamping when needed while enabling easy installation and removal
Solution Approach 2:
The Kevlar lines are pre-positioned between the inner and outer screw thread portions before the screwing action is applied. This preliminary placement ensures that when the screw threads are engaged, the clamping force is immediately applied to the correctly positioned Kevlar lines, achieving strong clamping without requiring complex adjustment mechanisms during assembly

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables secure connection and easy assembly/disassembly of optical fibers of different sizes, enhancing adaptability and convenience by ensuring maximum tightness of Kevlar line clamping and accommodating various fiber types within the same connector type.
Implementation Method 1
an elastic member sleeved on an end of the fiber clamping assembly away from the fiber ferrule
Implementation Method 2
The boot includes an inner screw thread portion and defines a through hole therein for an optical fiber extending therethrough. The boot is sleeved on the housing, and the inner screw thread portion of the boot engages with the outer screw thread portion to secure the boot to the housing.
