Mobile Termination Table for Cable Spool Pre-Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing multiple independent cables into a conduit are inefficient, often resulting in cable damage during installation, excessive waste due to multiple cuts, and the need for ad hoc pulling heads, which are time-consuming and costly to create.
Innovation Solution
A mobile termination table system that positions between supply spools and a single spool, allowing for a single cut per cable, automatic handling of different sizes, and facilitates the installation of axially spaced crimp connectors for efficient cable termination without wasting cable material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple cables are cut to different lengths at a termination table, then each cable can be properly terminated, but excessive cable material is wasted
Solution Approach 1:
Cables are pre-cut to uniform lengths on the spool before being mounted onto the pulling head. This preliminary cutting action eliminates the need for individual cable cutting at the termination table, thereby preventing material waste while ensuring proper termination capability.
Solution Approach 2:
The system segments the cable handling process into two distinct phases: (1) uniform pre-cutting on the spool, and (2) mounting pre-cut cables onto the pulling head. This segmentation allows each phase to be optimized independently, with the first phase ensuring material efficiency and the second phase ensuring proper termination.
2Adaptability or versatility
If ad hoc pulling heads are created at the jobsite, then flexibility in installation is achieved, but installation time and labor cost increase
Solution Approach 1:
Multiple cables are pre-mounted onto the pulling head at the spool location before being transported to the jobsite. This preliminary assembly eliminates the need for time-consuming ad hoc creation of pulling heads at the installation location, significantly reducing installation time while maintaining flexibility through pre-configured cable arrangements.
Solution Approach 2:
The system skips the time-consuming step of creating pulling heads at the jobsite by having them pre-assembled at the spool. This allows the installation process to rush through to the critical phase of cable deployment without the delay of on-site assembly operations.
3Ease of manufacture
If all crimp connectors are placed at one location on multiple cables, then assembly is simplified, but the cables cannot be installed in properly sized conduits
Solution Approach 1:
The system segments the crimp connector placement along the cable length by spacing them at predetermined intervals (e.g., 6 inches apart). This spatial segmentation ensures that connectors are distributed along the cable rather than clustered, allowing proper clearance in conduit while maintaining systematic assembly procedures.
Solution Approach 2:
Instead of placing all connectors at the same longitudinal position (one-dimensional clustering), the system distributes them along the cable length (utilizing the longitudinal dimension). This dimensional distribution resolves the conflict between assembly simplicity and conduit installation requirements.

AI summary
The method of attaching a pulling head to two or more wires or cables for installation in a conduit, comprising providing a first area for attaching the pulling head, placing two or more wire or cable supply spools on a first side of the first area, placing a receiving spool on the opposite or second side of the first area, feeding a portion of the wires or cables from the wire or cable supply spools onto the receiving spool, placing a terminating table in the first area below the wires or cables, cutting the wires or cables at staggered length from the receiving spool, stripping a portion of the covering from the wires or cables from the outer diameter of the two or more wires or cables, installing a connection onto each of the two or more wires or cables.
