Attic Wire Guide Structure for Insulation-Safe Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing electrical wiring in construction often damage the dielectric insulation, leading to signal degradation and fire hazards, and make it difficult to replace wiring without damaging the surrounding structure.
Innovation Solution
A specially configured electrical wire/cable guide with a cylindrical shape, open ends, axial bore, and apertures for secure fastening, allowing easy access and support of electrical lines without direct contact with the support surface, eliminating the need for nails, staples, or clamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If electrical wiring is nailed, stapled or clamped into place using conventional methods, then the wiring is securely fixed to the support structure, but the dielectric insulation is damaged creating shock or fire hazards
Solution Approach 1:
The patent introduces a wire guide as an intermediary component between the electrical wiring and the support structure. The wire guide has a body with a bore that receives the wiring, and fastening features that attach the guide to the support structure without directly contacting the wiring. This mediator prevents direct mechanical damage to the dielectric insulation while still providing secure fixation.
2Strength
If conventional wire holders with straps and clamps are used to secure electrical cable, then the cable is held firmly, but the installation process requires bending and straightening components making it complex and time-consuming
Solution Approach 1:
The wire guide is designed as a single integrated component with distinct functional segments: a body portion, a bore for cable reception, and fastening features. This segmentation of functions within a single piece eliminates the need for multiple separate components like straps and clamps, simplifying both manufacturing and installation while maintaining secure cable holding capability.
Solution Approach 2:
The patent combines multiple functions into a single wire guide component: the body provides structural support, the bore provides cable guidance and protection, and the fastening features provide secure attachment. This merging of functions into one component eliminates the need for separate straps, clamps, and fasteners, reducing installation complexity.
3Strength
If electrical wiring is fixedly stapled or nailed in wood frame members, then the wiring is securely mounted, but it becomes exceedingly difficult to remove and reroute or replace the electrical cable
Solution Approach 1:
The wire guide incorporates removable fastening features that allow the guide to be dynamically attached and detached from the support structure. This dynamic mounting system enables easy removal and reinstallation of the wire guide with new cables, contrasting with fixed nail or staple methods that permanently damage the support structure upon removal.
4Reliability
If the wire guide body is made durable and robust to protect electrical lines, then the electrical lines are well protected, but the wire guide becomes heavier and more difficult to install in hard-to-reach areas
Solution Approach 1:
The wire guide body is designed with a streamlined, elongated shape that provides adequate protection for the electrical lines while minimizing material usage. The bore dimensions are optimized to provide just enough clearance for the cable, avoiding excessive material thickness. This design achieves reliable line protection while keeping the guide lightweight for easy installation in attic and wall spaces.

AI summary
An electrical line guide includes a single and unitary body having a cylindrical shape and including an open proximal end and an open distal end coaxially aligned therewith and opposed therefrom, an outer surface extended from the open proximal end to the open distal end, an axial bore linearly extended from the open proximal end to the open distal end, a first aperture located at an anterior side of the outer surface, and a second aperture located at a posterior side of the outer surface. A fastener is removably penetrated entirely through the first aperture and partially through the second aperture and terminating in an existing support surface. The axial bore is configured to receive a plurality of electrical lines therethrough while the single and unitary body is supported at an elevated height relative to the existing support surface.
