Angled Support Wire Transport System Resisting Racking Forces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport systems for wire spools are prone to deformation and failure under the weight and inertia of heavy spools, especially when multiple spools are moved or cables are pulled, leading to racking and potential permanent damage to upright standards.
Innovation Solution
A transport system with angled supports forming acute angles between a mobile assembly and an upper assembly, which includes casters for directional movement and axles for dispensing cable, resisting racking forces and allowing multiple spools to be carried without deforming the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple heavy wire spools are supported on vertical posts, then the ability to transport and dispense wire is improved, but the posts are subjected to racking forces and deformation that may permanently damage the transport system
Solution Approach 1:
The invention transitions from vertical support posts to angled support members that extend diagonally between the mobile assembly and upper assembly. This dimensional change in support orientation allows the structure to resist racking forces through geometric stability while maintaining wire dispensing functionality.
Solution Approach 2:
The support structure employs asymmetric angled members rather than symmetric vertical posts. The angled supports create triangular geometric relationships that inherently resist lateral deformation, transforming the symmetric vertical load-bearing structure into an asymmetric configuration that provides superior racking resistance.
2Productivity
If wire spools are pulled in the same direction to enable bundling, then cable deployment efficiency is improved, but the upright standards experience longitudinal deformation and potential failure
Solution Approach 1:
The invention changes the orientation of support members from vertical to angled, creating a three-dimensional triangular support structure. This dimensional change allows the system to withstand longitudinal pulling forces during cable deployment without deforming the standards, as the angled geometry distributes forces across multiple members rather than concentrating them on vertical posts.
3Ease of operation
If heavy wire spools are moved about the work area, then mobility and accessibility are improved, but the inertia of the spools causes deformation and failure of the transport system
Solution Approach 1:
The invention employs angled support members that create a three-dimensional triangular framework between the mobile assembly and upper assembly. This geometric configuration provides inherent stability that resists deformation from spool inertia during movement, while the caster wheels maintain mobility. The angled supports distribute dynamic loads more effectively than vertical posts would.

AI summary
A transport system may be provided for transporting spools of flexible material, such as wire or tubing, about a construction site and for dispensing the material from a spool rotatingly mounted on an angled support of the transport system. The angled support may form an acute angle at its lower end with a central member of a mobile assembly and an acute angle at its upper end and a central member of an upper assembly, so that the angled support and central members are vertically coplanar along a longitudinal centerline of the transport system. In this manner, more spools of material may be carried between the extents of the central members than would be possible if the angled supports were perpendicular to the central members. Furthermore, the angled supports may resist racking forces resulting from longitudinal movement of the system and from resistance to dispensing of material from the spools.
