Fence Cabling Device With Adapting Duct Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cabling devices for fences with posts are complex and time-consuming to attach and install, often requiring labor-intensive modifications to the posts, which compromises their strength and the protection of cables.
Innovation Solution
A cabling device featuring adaptable duct elements that extend around fence posts, forming a continuous duct with minimal openings, allowing easy cable insertion and protection, and incorporating connecting profiles for quick assembly and ballistic protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If openings are made in the posts to pass cables through, then cables can be positioned at the desired height, but the strength of the posts diminishes and the process becomes labour intensive
Solution Approach 1:
The cabling device is divided into separate modular components: linear duct elements that span between posts and adapting duct elements that connect around posts. This segmentation eliminates the need to modify posts while maintaining cable positioning capability through the modular assembly of duct segments.
Solution Approach 2:
Adapting duct elements serve as intermediary components that bridge the gap between linear duct elements at post locations. These adapting elements route cables around posts without requiring openings in the posts themselves, thus preserving post strength while enabling cable installation at desired heights.
2Ease of manufacture
If a cable duct is fixed upon the top side of the fence, then posts do not hinder connection, but the fixation process and cable application become complex and time consuming
Solution Approach 1:
The duct system is segmented into linear and adapting elements that can be independently positioned and connected. This allows installation to proceed in manageable sections rather than requiring complex full-duct installation, reducing overall installation time and complexity.
Solution Approach 2:
The duct elements are designed with flexible connection capabilities that allow for dynamic adjustment during installation. The adapting duct elements can be connected to linear elements in various configurations to accommodate different post positions, streamlining the installation process.
3Ease of operation
If cables are pulled through ducts and openings, then cables can be installed, but the process is difficult at the height of openings and cables are not well protected
Solution Approach 1:
The continuous duct is segmented into linear and adapting elements that connect around posts rather than through them. This maintains the enclosed protective structure while enabling cable installation at appropriate heights without difficult access points.
Solution Approach 2:
The adapting duct elements provide flexible routing around posts while maintaining the enclosed protective shell structure. This ensures cables remain protected throughout the entire duct length, including transition areas around posts, without requiring exposed cable sections at opening heights.
