Vineyard Post Quick-Release Cross-Arm Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vineyard poles with transverse arms are time-consuming to assemble and disassemble, prone to loose screw connections due to wind and temperature fluctuations, and lack efficient storage and handling solutions, especially when multiple wire planes are required for vine growth and shading.
Innovation Solution
A vineyard pole design featuring a base body with sheet metal legs and a transverse arm that can be quickly locked into place using a quick-release fastener, with integrated hooks and eyelets for wire support and additional openings for accessories, allowing for easy assembly, high rigidity, and space-saving storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cross arms are bolted to vineyard posts for better handling and storage, then ease of operation and storage is improved, but assembly time increases significantly
Solution Approach 1:
The vineyard post is divided into separate modular components: a base body and detachable cross arms. This segmentation allows the components to be stored separately and assembled quickly on-site without requiring complex pre-assembly operations, thus reducing assembly time while maintaining ease of handling and storage.
Solution Approach 2:
The base body is pre-formed with integrated openings and attachment features during manufacturing. These preliminary preparations eliminate the need for complex on-site assembly operations, allowing cross arms to be quickly attached to the pre-prepared base body, significantly reducing assembly time.
2Ease of operation
If screw connections are used to attach cross arms, then ease of assembly is improved, but reliability decreases due to loosening from wind and temperature fluctuations
Solution Approach 1:
The connection system transitions from static screw threads to a dynamic snap-fit mechanism. The cross arm includes a tapered portion that engages with a corresponding receptacle in the base body, creating a connection that is both easy to assemble and resistant to loosening under dynamic wind and temperature conditions, thus improving reliability while maintaining ease of assembly.
3Ease of operation
If cross arms are attached at a distance from the center of inertia, then ease of assembly is improved, but strength decreases due to additional torque requirements
Solution Approach 1:
The cross arm attachment geometry is designed with asymmetric features including a tapered portion and offset positioning that align with the base body's opening configuration. This asymmetric design allows the cross arm to be attached at an optimized position that reduces torque requirements while maintaining structural strength, resolving the contradiction between ease of assembly and load capacity.
4Adaptability or versatility
If multiple openings are provided in the base body for cross arm attachment, then adaptability is improved for various configurations, but device complexity increases
Solution Approach 1:
The base body is designed with multiple openings that can accommodate different cross arm configurations and orientations. These openings serve universal purposes for attaching cross arms in various positions and angles, providing adaptability for different vineyard layouts while avoiding the need for multiple specialized attachment mechanisms, thus not significantly increasing device complexity.

AI summary
A post (1) for holding wires (8) in viticulture and fruit growing, comprising a base body (2) with a first and second leg (4a, 4b) made of sheet metal, on which at least one transverse arm (12) extending substantially at a right angle to the longitudinal axis of the base body (2) is arranged, with a plurality of hooks and/or eyelets (6a, 6b) for holding the wires (8), is characterized in that an opening (10a, 10b) with an opening shape adapted to the cross-sectional shape of the transverse arm (12) is formed in the first and second legs (4a, 4b), through which the transverse arm (12) can be inserted into the base body (2) substantially at a right angle to the longitudinal axis until it reaches a locking position, and that a quick-release fastener (16) is provided which, in the locking position, forms a positive-locking connection between the base body (2) and the transverse arm (12). generated.
