Elastic Reversible Locking Element for Metal Wire Plant Stakes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for locking horizontal metal or plastic wires on vertical stakes in agricultural support grids are either labor-intensive, require complex manual handling, or result in bulky accessories that can damage wires or obstruct vegetation.
Innovation Solution
An elastic and reversible locking element with a specific geometry that allows for quick assembly by unskilled personnel, providing a strong and secure fixation of the wire to the stake with multiple points of contact, thus preventing horizontal sliding and ensuring stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a section of metal wire is wrapped around the stake and tightened by clamps or pliers, then the horizontal wire is firmly joined to the vertical stake, but the manual work required for each individual application becomes demanding and time-consuming
Solution Approach 1:
The locking element is designed to automatically lock the wire to the stake without requiring external tools like clamps or pliers. The element's own structure enables it to tighten and secure the wire through its geometry and elastic properties, making the system self-sufficient and eliminating the need for additional manual operations.
Solution Approach 2:
The invention extracts the tightening function from separate tools (clamps, pliers) and integrates it into the locking element itself. By removing the need for external tightening devices, the process becomes simpler and faster while maintaining connection strength.
2Adaptability or versatility
If a section of metal wire is arranged oblique to wrap around both the vertical stake and horizontal wire, then both components can be connected, but the wire allows horizontal sliding and becomes less applicable
Solution Approach 1:
The locking element is divided into distinct functional segments: a first end with folds for embracing the wire, a central portion for positioning, and a second end for locking against the stake. This segmentation allows each part to perform its specific function optimally, preventing wire sliding while maintaining connectivity.
Solution Approach 2:
Instead of wrapping the wire obliquely around the stake, the invention inverts the approach by using a structured element that engages the wire perpendicularly and locks it against the stake. This reversal of the connection geometry eliminates the sliding problem while maintaining adaptability.
3Reliability
If a specific accessory with a screwdriver lever is used to tighten and lock the wire, then the stake is optimally locked on the wire, but the accessory cannot be reused and is bulky, disturbing vegetation and potentially damaging the wire
Solution Approach 1:
The locking element is designed as a simple, inexpensive, disposable component that can be quickly applied and then discarded or reused if needed. Its simplicity reduces bulkiness and eliminates the need for complex reusable accessories with multiple parts, while still achieving optimal locking.
Solution Approach 2:
The invention merges the locking and tightening functions into a single integrated element that directly engages the wire and stake without requiring separate accessories. This consolidation eliminates the bulkiness of multi-component systems while maintaining reliable locking.
4Strength
If a vertical hook with saddle portion and folds is used to engage the stake and wire, then strong tightening is achieved, but the element requires complex processing and individual handling of multiple parts
Solution Approach 1:
The locking element is segmented into functional zones (wire-embracing folds, central positioning portion, stake-locking end) that can be formed through simple sequential operations. This segmentation allows complex functionality to be achieved through straightforward manufacturing steps rather than intricate processing.
Solution Approach 2:
The invention achieves strong tightening through controlled elastic deformation of the locking element during installation. By utilizing material elasticity and controlled bending, the element generates sufficient locking force without requiring complex heat treatment, alloying, or other advanced manufacturing processes.
