Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for pulling fiber optic connectors through elongated pipes are either inconvenient and require specialized tools for assembly and disassembly or expose the ferrule assembly to damage and contamination.
Innovation Solution
A cable pulling assembly with a pulling device that features engagement portions and a spring mechanism for easy assembly and disassembly, along with a seal ring to protect the ferrule assembly from damage and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pulling device is sleeved on the connector housing and a rope is tied on the pulling device, then the connector can be pulled through the elongated pipe, but a special tool must be used to assemble and disassemble the pulling device, making it inconvenient and complicated
Solution Approach 1:
The pulling device is divided into multiple components: a pulling body with engagement portions, a connector housing with corresponding engagement features, and a spring mechanism. This segmentation allows the pulling device to be easily assembled and disassembled without special tools, while maintaining its functionality during the pulling operation.
Solution Approach 2:
A spring mechanism is introduced to provide dynamic engagement and disengagement of the pulling device. The spring allows the engagement portions to automatically engage with the connector housing during assembly and can be compressed to release the engagement for disassembly, transforming a static connection into a dynamic one that is easier to operate.
2Ease of operation
If a rope is directly tied on the housing of the connector, then the connector can be pulled through the elongated pipe, but the ferrule assembly is directly exposed and may be scratched by the pipe wall or contaminated by dirt
Solution Approach 1:
The pulling device serves as an intermediary component between the rope and the connector housing. It provides a protected interface where the rope connects to the pulling body, which then engages with the connector housing through engagement portions. This intermediary structure prevents direct contact between the rope/tie and the ferrule assembly, eliminating the risk of scratching or contamination while maintaining pulling functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and simple assembly and disassembly of the pulling device on the connector in the field, while protecting the ferrule assembly from scratches and contamination during the pulling process.
Implementation Method 1
a spring is received in the housing of the connector, and when the pulling device is connected to the housing of the connector, the spring exerts an axial pushing force on the pulling device, so as to hold the protrusion in the recess
