Fencing Device Guide System for Rapid Post Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fencing devices for temporary fences are complex and time-consuming to install and remove, particularly in applications like livestock farming and nature reserves where permanent fences are not permitted.
Innovation Solution
A fencing device with posts having a pointed lower end and a guide system that allows for easy driving into and extraction from the ground, featuring a top guide profile, side guide profiles, and a bottom guide profile to stabilize and facilitate the installation and removal process, with the device capable of rotating to invert for efficient post extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the known device uses guide means in a trench made in the ground, then the fence can be installed, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent extracts the guide function from the ground trench and relocates it to a movable guide structure attached to the fencing device. This guide structure can be easily assembled and disassembled, eliminating the need for complex ground preparation while maintaining effective post guidance during installation
Solution Approach 2:
The guide structure is designed to be movable and adjustable rather than fixed in the ground. It can be positioned, moved, and repositioned as needed during the fencing installation process, allowing for flexible operation across different terrains and reducing setup time compared to fixed trench-based guidance
2Productivity
If the fence is installed using traditional methods, then the posts can be secured, but the removal process becomes time-consuming
Solution Approach 1:
The patent applies inversion by designing the guide structure to perform dual functions: guiding posts into the ground during installation and guiding posts out of the ground during removal. By inverting the operational mode of the same structure, the device enables rapid deployment and retrieval without requiring separate installation and removal equipment
Solution Approach 2:
The guide structure is designed as a multi-functional component that serves both installation and removal operations. The same guide rails and support structures that facilitate post insertion also enable post extraction, eliminating the need for separate specialized equipment and reducing overall time loss
3Device complexity
If a simple guide structure is used, then the device complexity is reduced, but the stability and precision of post installation may be compromised
Solution Approach 1:
The guide structure is segmented into multiple independent components including guide rails, support frames, and adjustment mechanisms. This segmentation allows each component to be optimized for its specific function while maintaining overall structural stability, and enables easy assembly and disassembly without requiring complex integrated designs

AI summary
A fencing device 1 comprises installing means for driving the posts 5 of the fence into the ground. These posts are provided with a pointed lower end 9 so that they can easily be driven into the ground. The net with the posts attached thereto is wound on a reel 11. The installing means gradually guide the posts from the reel to the ground, while the lower ends of the posts are driven into the ground. For guiding the posts, the installing means are formed by a guide consisting of a top guide profile 13, two side guide profiles 15 and a bottom guide profile 17. When a temporary fence is erected, the first post is to be driven into the ground manually and supported with a cable or pole. Subsequently, the fence will be unwound from the reel while the trailer is moved on.
