Parachute Cable Sleeve for Fiber End Protection in Conduits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable installation methods, such as pulling or cable jetting, can damage the end of fiber-optic cables due to pressure, and installing connectors after installation makes precise calibration difficult.
Innovation Solution
A cable-jetting installation sleeve with an expandable section and a parachute aids in installing fiber-optic cables by receiving the cable end, expanding to fit, and contracting to hold it in place, allowing for easy removal and precise connector placement without damaging the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cable pulling or cable jetting methods are used to install cables, then cable installation can be completed, but the end of the cable is damaged due to pressure
Solution Approach 1:
The patent introduces a cable installation device as an intermediary between the cable and the installation environment. This device includes a protective sleeve that receives the cable end and a parachute that distributes installation forces, preventing direct pressure on the cable end while enabling successful cable installation through conduits
Solution Approach 2:
The protective sleeve is designed to receive and protect the cable end before installation begins. The sleeve acts as a cushioning element that prevents damage to the cable end during the installation process, allowing the cable to be pulled or jetted without direct contact between the installation forces and the cable end
2Ease of operation
If connectors are installed after cable installation, then connector calibration becomes difficult
Solution Approach 1:
The protective sleeve is designed to hold the cable end in a predetermined position during installation. This preliminary positioning action ensures that when connectors are later installed, the cable end is already in the correct position, making connector calibration easier and more precise
3Productivity
If traditional cable installation methods are used, then additional machinery is required for connector installation
Solution Approach 1:
The patent combines the cable protection function and the installation aid function into a single integrated device. The protective sleeve and parachute work together as one system, eliminating the need for separate machinery for cable installation and connector installation, thereby reducing device complexity while maintaining productivity
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
The solution protects the cable end during installation, simplifies connector attachment, and reduces the need for additional machinery, enabling efficient and precise cable installation with reduced material and time costs.
Implementation Method 1
The parachute can capture air flowing through the conduit to pull the cable through the conduit

AI summary
A cable-jetting installation sleeve can be used to advance a fiber-optic cable through a conduit. The cable-jetting installation sleeve can include a housing and an expandable section. The expandable section can include an opening which can be expanded to receive or remove an end of the cable and contracted to engage the cable with the expandable section. A parachute can be positioned on one end of the cable-jetting installation sleeve. The parachute can be pushed by compressed air in the conduit to advance the cable-jetting installation sleeve through the conduit.
