Spring-Loaded Fence Clip for Parallel Wire Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for attaching objects to chain link fences lack the ability to provide fast, easy, secure, and semi-permanent structural attachment while being adaptable to varying fence sizes, and none engage precisely with two parallel wires by applying force in the direction of the fence plane.
Innovation Solution
A fence clip with structural members that mechanically couple to engage peripheral retaining grooves with two parallel wires, allowing for internal or external compression or expansion to grip the wires, and can be locked in place for semi-permanent attachment, using a spring mechanism or other mechanical elements like hinges and levers for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hangers and clips are used to attach objects to chain link fences, then attachment is possible, but the attachment process is time-consuming and requires tools
Solution Approach 1:
The fence clip is divided into two separate structural members (first and second members) that can be independently positioned and engaged with the fence wires. This segmentation allows for easier manipulation and faster attachment compared to traditional single-piece hangers, as each member can be independently aligned with the parallel wires of the chain link fence.
Solution Approach 2:
The fence clip incorporates a spring mechanism that provides dynamic movement between the two structural members. The spring allows the members to move relative to each other during attachment and removal, enabling tool-less operation. The elastic element stores and releases energy to facilitate quick engagement and disengagement without requiring external tools or excessive manual force.
2Reliability
If traditional hangers are used, then attachment can be made, but the attachment is not secure or semi-permanent
Solution Approach 1:
The locking mechanism is pre-configured within the fence clip structure, with the spring already positioned to engage the retention feature. When the two structural members are brought together and engaged with the fence wires, the locking action occurs automatically without requiring additional steps. This preliminary configuration ensures secure attachment while maintaining ease of removal by simply reversing the engagement process.
Solution Approach 2:
The fence clip uses a self-locking mechanism where the spring automatically engages with a retention feature on the opposing structural member when the clip is properly positioned on the fence wires. The elastic element maintains constant pressure to keep the connection secure without requiring external fasteners or tools. For removal, the user simply applies force in the opposite direction to disengage the spring from the retention feature, providing both security and ease of removal.
3Reliability
If fence clips are designed for specific fence sizes, then secure attachment is achieved, but adaptability to varying fence sizes is limited
Solution Approach 1:
The fence clip is designed with two structural members that can independently engage with parallel wires of varying distances. The spring mechanism provides adjustable tension to accommodate different fence configurations and wire spacings. This universal design allows the same clip to securely attach to various chain link fence sizes and types, eliminating the need for multiple specialized clip variants.
4Strength
If structural members are made rigid for strong attachment, then connection strength is improved, but the ability to accommodate different fence sizes is reduced
Solution Approach 1:
The spring mechanism allows the distance and relative positioning between the two structural members to be dynamically adjusted. When the clip is engaged with the fence wires, the spring compresses or extends to accommodate the specific wire spacing, while the structural members maintain their rigid geometry for strong attachment. This parameter change capability enables the same rigid structure to adapt to various fence configurations and wire distances.

AI summary
The purpose of this clip is to attach to a chain link fence and provide a connection point for a device or structure. The method of attachment is provided by two mechanically combined structural members with peripheral retaining grooves that fit the fence wire. The clip is compressed or expanded to grip two parallel wires of a chain link fence. The structural members of the clip move the retaining grooves in parallel for a precise fit with the fence. The clip can be engaged with the fence in an internal or external manner. In the preferred embodiment of this invention, the chain link fence clip utilizes a spring to force the two retaining grooves into engagement with the fence. The clip can be locked in place for a strong semi-permanent connection. Springs, cams, linkages, and screws can be used to automate engagement for quick tool-less attachment and removal.
