Vine Post Wire Retention via Segmented Hook Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vine post systems for supporting iron wires face challenges in quickly and safely mounting wires without skilled labor, with existing solutions often requiring complex shaping or deformation, and struggling to prevent accidental detachment due to wind or vandalism.
Innovation Solution
A vine post with an elongated metal body featuring protrusions in the cut-out zones of the windows, allowing for simple clipping and retention of the wire, preventing accidental detachment while facilitating voluntary extraction through a non-straight trajectory, and optionally incorporating additional features like longitudinal nerves for increased rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hooks are provided in the open position obtained by deforming the material of the post itself, then wire mounting is simplified, but the wire is not fixed and can be easily detached
Solution Approach 1:
The hook is segmented into a main body and a separate retaining element (tab or protrusion). The hook body provides the opening/closing function for easy wire mounting, while the retaining element provides the locking function to prevent accidental detachment. This segmentation allows each component to perform its specific function effectively.
Solution Approach 2:
A retaining tab or protrusion acts as an intermediary element between the hook and the wire. This intermediate structure provides the locking mechanism that directly engages with the wire, preventing detachment while not interfering with the basic hook function of holding the wire.
2Reliability
If complex shaping or in situ deformation is used to retain the wire, then wire retention is improved, but the structure complexity and manufacturing difficulty increase
Solution Approach 1:
The retention function is extracted from the complex shaping/deformation process and implemented through a simple, separate retaining element (tab or protrusion) that can be easily formed during manufacturing. This extraction simplifies the overall structure while maintaining the retention function.
Solution Approach 2:
The retaining tab or protrusion is designed as a simple, easily manufactured feature that can be formed as part of the standard production process. It accepts simple stamping or deformation operations during manufacturing, making it cost-effective and suitable for mass production without requiring complex shaping.
3Ease of operation
If independent parts welded to the post are used to create open position hooks, then wire mounting is facilitated, but additional components and welding operations are required
Solution Approach 1:
The retaining element is merged with the hook body as an integrated component formed from the same material. The tab or protrusion is created as part of the same stamping or deformation process that forms the hook itself, eliminating the need for separate parts and welding operations.
Solution Approach 2:
The hook structure is designed to perform multiple functions: the main body provides the hook function for wire mounting, while the integrated retaining element provides the locking function. This multi-functionality is achieved within a single component, eliminating the need for separate welded parts.

AI summary
Vine stake, structured in an enlarged metal body (1) with a plurality of hooks obtained by cutting and deforming the portions (11) which protrude from the body of the stake (1) and create corresponding windows (12) there.This stake includes means for retaining the wire (2) by preventing it from unintentionally/accidentally coming loose; these means being, in each portion/hook (11): - one or more protrusions (13) made in the metal body (1), arranged in the cut-out area of these windows (12) by extending laterally from the corresponding portion/hook (11) and by forcing the wire (2) to follow a non-straight trajectory; or - a support (111), an intermediate wall (112) and an end wall (113) inclined in opposition to the body of the stake (1) which has, at least, a stamping (14) for each window (12) by deforming its perimeter and by preventing the portion/hook (11) from being accidentally introduced into the body of the stake (1).
