Removable Cable Pulling Assembly for Fiber Optic SC Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable pullers often struggle to route fiber optic cables through small enclosed spaces due to their size, making it difficult to install fiber optic cables in existing structures or new construction.
Innovation Solution
A cable pulling assembly with a removable enclosure that includes a first and second member, each defining a cavity to engage an SC-type connector, allowing for the transfer of tensile force to the fiber optic cable's strength layer, facilitating the pulling of the cable through tight spaces.

Engineering Contradiction Analysis
1Volume of moving object
If traditional cable pullers are used to pull fiber optic cables through enclosed spaces, then the cable can be pulled through larger openings, but the cable cannot be pulled through small enclosed spaces due to the size of the cable puller
Solution Approach 1:
The cable pulling assembly is divided into multiple separable components including a first member, second member, and optional third member that can be assembled and disassembled. This segmentation allows the assembly to be broken down into smaller parts that can pass through small enclosed spaces, while still providing sufficient pulling capacity when assembled together.
Solution Approach 2:
The cable pulling assembly transitions from a static, fixed-size tool to a dynamic, reconfigurable system. The removable members can be attached and detached based on the specific requirements of the enclosed space, allowing the assembly to adapt its size and configuration to match the constraints of different installation environments.
2Reliability
If a removable enclosure with multiple members is used to engage the SC connector, then the tensile force can be transferred to the strength layer, but the device complexity increases
Solution Approach 1:
The enclosure is segmented into multiple members that can be separately manufactured and assembled. Each member has a specific function (engaging different portions of the SC connector), which simplifies the design and manufacturing of individual components while achieving the overall goal of reliable tensile force transfer to the strength layer.
Solution Approach 2:
The multi-member enclosure design serves multiple functions: it provides secure engagement with the SC connector through different members, enables reliable tensile force transfer to the strength layer, and allows for flexible configuration to accommodate different cable and connector types, thereby justifying the increased device complexity through enhanced versatility and reliability.

AI summary
A cable pulling assembly includes an enclosure that is adapted for enclosing an SC type connector end of a fiber optic cable. The enclosure includes a first member that defines a first cavity. The first cavity is adapted to receive a portion of a SC connector. The enclosure further includes a second member that is selectively engaged to the first member. The second member defines a second cavity. The second member may be structurally identical to the first member. The enclosure is adapted to transfer a tensile force applied to the enclosure to the strength layer of the fiber optic cable.
