Fiberglass Temporary Fence for Electrical Sites
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current temporary fencing systems are not adequately secure for electrical work sites due to being easily scalable, cuttable, and lacking sufficient strength and rigidity, and they are often electrically conductive, which poses a risk for electric utilities and contractors.
Innovation Solution
A temporary fencing assembly made from fiber-reinforced, electrically non-conductive thermoset resin materials, such as fiberglass, featuring rotatable posts and panels with hinge pins and pickets, providing a sturdy and easy-to-assemble enclosure that prevents access and maintains electrical safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional chain link fencing is used, then the fencing is easy to install and relatively lightweight, but it is electrically conductive and lacks sufficient strength and rigidity for secure electrical work sites
Solution Approach 1:
The patent applies composite materials by constructing the fence from multiple components (panels, posts, rails) made from electrically non-conductive materials such as fiberglass-reinforced plastic or other insulating materials. This composite structure provides both the required mechanical strength and electrical insulation properties, resolving the contradiction between security effectiveness and electrical conductivity.
2Ease of operation
If conventional chain link fencing is used, then the fencing is easy to scale and cut, but it lacks sufficient strength and rigidity to adequately limit access
Solution Approach 1:
The patent applies segmentation by dividing the fence into modular components including panels with pickets, vertical posts, and horizontal rails that can be independently assembled and connected. This modular design maintains ease of assembly while significantly improving structural strength and rigidity compared to conventional chain link fencing.
Solution Approach 2:
The use of composite materials such as fiberglass-reinforced plastic provides both the necessary structural strength and rigidity while maintaining the ease of assembly through standardized connection mechanisms between modular components.
3Object-affected harmful factors
If plastic mesh fencing is used, then the fencing is electrically non-conductive, but it lacks sufficient strength and rigidity to adequately limit access
Solution Approach 1:
The patent uses composite materials such as fiberglass-reinforced plastic for the panels, posts, and rails, providing both electrical non-conductivity and the necessary structural strength and rigidity that plain plastic mesh lacks.
Solution Approach 2:
The segmented modular design with rigid panels containing closely spaced pickets, supported by sturdy vertical posts and horizontal rails, achieves the required structural strength while maintaining electrical insulation properties.

AI summary
A temporary fencing assembly comprises a plurality of rectangular fence panels formed from fiberglass supported between fiberglass posts pivotally supported on a base formed from fiberglass. Each post includes two sets of vertically aligned hinge pins or hinge pin receivers projecting outward from opposite sides of the post. The fence panels are formed from rectangular, fiberglass tubing formed into a rectangular frame, each panel including a pair of side rails, a top rail and a bottom rail. The base includes a mounting stud welded to a mounting stud base. Two fiberglass T-posts are secured to the mounting stud base with legs of the T-posts extending under and covering a web of the mounting stud base.
