Solution Overview
Problem
The installation of pulling heads for multiple conductor cabling is often done ad hoc at job sites, leading to increased time, expense, and risk of conductor damage due to improper force application, which can result in costly repairs or replacement.
Innovation Solution
A workstation with integrated tools and components for efficiently installing pulling head assemblies, including a conductor clamp, cutting guide, stripping tool, and crimping tool, allows for standardized and reliable attachment of pulling eyes to conductors, reducing the risk of damage and improving installation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pulling heads are created ad hoc at the jobsite, then flexibility and adaptability are improved, but installation time and expense increase, and the risk of conductor damage increases
Solution Approach 1:
The patent applies preliminary action by pre-assembling pulling head assemblies at the manufacturer's facility before delivery to the jobsite. The pulling heads are pre-attached to conductors using standardized procedures and equipment, so that upon arrival at the jobsite, they require minimal setup or adjustment. This eliminates the time-consuming ad hoc creation process while maintaining the necessary adaptability through pre-configured assembly variations.
2Adaptability or versatility
If pulling heads are created ad hoc at the jobsite, then on-site customization is improved, but installation expense and complexity increase
Solution Approach 1:
The patent applies segmentation by dividing the pulling head assembly into standardized modular components that can be pre-assembled at the manufacturer's facility. Each pulling head is constructed as a discrete, pre-configured unit with standardized attachment mechanisms. This modular approach maintains customization capability for different conductor types while significantly reducing on-site installation complexity, as the segmented units require only simple assembly rather than complex on-site fabrication.
3Ease of operation
If force is applied to the cabling improperly during pulling, then pulling force application is simplified, but conductor damage increases
Solution Approach 1:
The patent applies the intermediary principle by introducing a pulling eye as a mediator between the pulling rope and the conductor. The pulling eye is a specially designed attachment component that distributes pulling forces evenly across the conductor and pulling rope interface. This intermediary element simplifies the ease of operation by providing a straightforward attachment point while simultaneously protecting conductor integrity by preventing stress concentration and improper force application that would occur with direct rope-to-conductor attachment.
4Loss of time
If pulling heads are pre-assembled by the manufacturer, then installation time and expense are reduced, but on-site adaptability decreases
Solution Approach 1:
The patent applies universality by designing pulling head assemblies with standardized components and attachment mechanisms that can accommodate multiple conductor types and configurations. The pulling eyes and attachment hardware are designed to be universally compatible across different conductor sizes and materials. This allows pre-assembled units to maintain on-site adaptability while benefiting from the time and expense reductions of manufacturer pre-assembly, as the universal design enables flexible deployment in various installation scenarios without requiring complex on-site modifications.

AI summary
A workstation and method for the installation of a pulling head assembly onto one or more conductors of a cabling system are provided. The workstation incorporates one or more of: a conductor clamp that holds the conductors of the cabling system in place during the installation of the pulling head assembly; a cutting guide having indicia marks that indicate the lengths to which to cut the conductors in order to achieve a staggered pattern of pulling eyes attached to the conductors in the pulling head assembly; a stripping tool that is used to remove a portion of the insulation from the terminal end of each conductor so that the end of the conductor may be inserted into the pulling eye; and a crimping tool that is used to crimp the pulling eyes onto the terminal ends of each of the conductors.
