Swing Arm Training System for Vine Shoot Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grape vine training systems are labor-intensive and ineffective in preventing foliage shading, leading to reduced fruit quality due to inadequate sun exposure and uneven distribution of shoots.
Innovation Solution
The Swing Arm Training System (SATS) uses a pair of rotating swing arms with a grid or wires to capture and train shoots, providing lateral support and adjusting to optimize sun exposure, reducing labor and shading issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional trellis systems with catch wires are used to position shoots, then shoots can be contained within a framework, but shoots become crowded and overlap leading to foliage shading and reduced sun exposure
Solution Approach 1:
The patent employs dynamic catch wires that can move and adjust their position automatically as shoots grow. The catch wires are connected to a mechanism that allows them to shift laterally, enabling the system to adapt to shoot growth patterns and maintain optimal spacing. This dynamic adjustment prevents foliage shading by ensuring shoots remain separated and evenly distributed throughout the growing season, thereby maintaining adequate sun exposure for all leaves.
Solution Approach 2:
The system utilizes the natural growth force of the shoots themselves to drive the positioning mechanism. As shoots grow upward, they automatically engage with and move the catch wires into their proper positions without requiring external intervention. The shoots' own growth momentum serves to distribute them evenly across the trellis framework, eliminating the need for manual positioning while preventing overcrowding and shading.
2Manufacturing precision
If manual positioning of shoots within catch wires is performed, then shoot distribution can be controlled, but the process becomes extremely labor-intensive and time-consuming
Solution Approach 1:
The patent implements a self-positioning mechanism where shoots automatically engage with the catch wires through their own growth motion. As shoots emerge and grow upward from the canopy, they naturally encounter the catch wires and are guided into their designated positions without human intervention. This self-service approach maintains precise control over shoot distribution while completely eliminating the labor-intensive manual positioning process, thereby dramatically improving productivity.
Solution Approach 2:
The catch wires are pre-positioned and configured in advance to anticipate shoot growth patterns. The system is set up beforehand with wires at specific intervals and angles that guide shoots into optimal positions as they grow. This preliminary configuration ensures that when shoots emerge, they automatically follow the pre-established pathways, achieving precise distribution control without requiring real-time manual adjustment and thus maintaining high productivity.
3Stability of the object's composition
If catch wires are used to hold shoots in position, then shoots can be prevented from moving randomly, but shoots still bunch together along the axial direction and fail to achieve uniform distribution
Solution Approach 1:
The patent employs dynamic catch wires that can move laterally along the trellis structure rather than being fixed in rigid positions. These movable wires respond to shoot growth and can adjust their positions to distribute shoots more uniformly along the axial direction. The dynamic nature of the wires allows them to prevent random movement while simultaneously avoiding the bunching effect of static wires, achieving both position stability and uniform distribution.
Solution Approach 2:
The catch wire system is divided into multiple independent segments or sections along the trellis length. Each segment can move and adjust independently based on local shoot density and growth patterns. This segmentation allows different portions of the trellis to be optimized individually, preventing the uniform bunching that occurs with a single rigid wire system while maintaining overall position stability through coordinated adjustment of multiple segments.

AI summary
An apparatus and method for training a grape vine. The apparatus is a swing arm supporting a linear grid composed of transverse and longitudinal elements that are configured to result in a network of spaces that are sized to capture and separate the grape vine shoots. The apparatus is mobile within the vine canopy serving various functions as the growing season progresses. The mobility of the grid apparatus allows repositioning throughout the growing season while still retaining the shoots within the grid openings.
