Movable Hook Attachment Device for Expanded Metal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment devices for expanded metal and fence systems are not easily installable and lack robustness, making them inadequate for securement purposes.
Innovation Solution
A flat plate with movable hooks, spaced at specific intervals, that can be securely attached to expanded metal or fence systems, allowing for easy installation and robust anchoring of additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing attachment devices are used for expanded metal, then securement is achieved, but installation is difficult and robustness is insufficient
Solution Approach 1:
The attachment device is divided into distinct functional segments: a plate body for mounting, hooks for engagement, and a securement structure for fastening. This segmentation allows each component to be optimized independently - the plate provides a stable base, the hooks provide flexible engagement options, and the securement structure provides reliable fastening, collectively resolving the contradiction between ease of installation and robustness
Solution Approach 2:
The hooks are designed to be movable relative to the plate, allowing them to flex and adapt during installation and use. This dynamic capability enables the hooks to easily engage with expanded metal surfaces during installation while maintaining strong, reliable securement once deployed, thus addressing both ease of operation and reliability requirements
2Productivity
If existing attachment devices are used for expanded metal, then securement is achieved, but installation time is excessive
Solution Approach 1:
The attachment device is pre-configured with hooks in specific positions spaced at natural number multiples of the hook spacing distance. This preliminary arrangement allows installers to quickly select and engage the appropriate hooks without complex measurement or adjustment during installation, significantly reducing installation time while maintaining securement effectiveness
Solution Approach 2:
The securement structure is designed to accommodate various types of items and mounting scenarios through its universal design. The hooks can be positioned at multiple predetermined locations, and the securement structure can accommodate different fastening methods, allowing a single device to handle diverse installation needs without requiring multiple specialized components, thereby improving installation efficiency

AI summary
A system including an attachment device having a generally flat plate having a securement structure, and two hooks movably coupled to the plate. A base end of each hook is spaced apart by a natural number multiple of a hook spacing distance, and the hook spacing distance is between about 1¾ inches and about 2¼ inches, or is between about 2¾ inches and about 3¼ inches.
