Chain-Link Fence Attachment Device Using Interwoven Nested Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for attaching objects to chain-link fences are often complex, require tools, lack load-bearing capacity, protrude from the fence, and are difficult to remove, and cannot securely hold objects or contain items within the fence.
Innovation Solution
An apparatus that interweaves with chain-link fences, allowing secure attachment and removal without fasteners, utilizing a gap and orifice design that merges with the fence's wire pattern, enabling one-person installation and high vibration resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If current attachment methods (clamps, chains, zip ties) are used, then objects can be attached to fences, but the attachment device requires tools for installation and removal, and lacks load-bearing capacity
Solution Approach 1:
The attachment device is divided into multiple functional segments: a first portion that interfaces with the fence wire, a second portion that holds the object, and a third portion that provides structural connection. This segmentation allows each part to be optimized for its specific function while collectively providing load-bearing capacity without requiring complex tool-based mechanisms.
Solution Approach 2:
The attachment device utilizes a nested structure where the third portion is received within the first portion, creating a compact, self-contained unit. This nesting arrangement reduces overall device complexity while maintaining the structural integrity and load-bearing capability through the interlocking geometry of the nested portions.
2Strength
If fasteners are used to secure attachments, then load-bearing capacity improves, but the fasteners protrude from the fence or are difficult to remove
Solution Approach 1:
Instead of using traditional fasteners that protrude from the fence surface, the attachment device inverts the approach by having the fence wire itself pass through and secure the device. The wire is threaded through the first portion and secured by the geometry of the nested portions, eliminating protrusions while maintaining secure attachment and easy removal through simple wire manipulation.
Solution Approach 2:
The attachment device is designed to be self-securing through its geometric configuration. The nested portions automatically engage and secure the wire without requiring additional fasteners or complex installation tools. The device serves its own securing function through its inherent structural design, enabling easy installation and removal by simply manipulating the wire.
3Reliability
If traditional attachment methods are used, then objects can be attached to fences, but multiple people are required for installation on tall fences
Solution Approach 1:
The attachment device incorporates dynamic elements that allow it to be installed and secured through simple manual manipulation of the wire. The nested portions can be easily assembled and disassembled by one person, and the device adapts to the fence wire configuration without requiring multiple people for positioning or securing.
Solution Approach 2:
The device is designed for self-service installation where a single person can complete the entire attachment process by simply threading the wire through the first portion and allowing the nested portions to automatically engage. The device secures itself without requiring assistance from multiple people, making it suitable for tall fences where access might be difficult.
4Reliability
If current attachment methods are used, then objects can be attached to fences, but the attachment cannot contain objects or hold them securely within the fence
Solution Approach 1:
The nested portion structure creates an enclosed space that can contain and secure objects within the fence attachment. The second portion, which is received within the first portion, forms a protective cavity that holds objects securely while maintaining a relatively simple overall device structure. This nesting arrangement provides object containment without requiring complex enclosures.

AI summary
An apparatus that has a shape and uses a method to securely interweave with chain-link fences and the like without additional fasteners or mechanisms of similar nature. The shape is comprised of an orifice and a gap merging into each other. The interweaving method is a set of orientation-dependent operations established with the relative locations of three elements: apparatus, entanglement and 2 bent wires forming the entanglement.
