Solution Overview
Problem
Existing methods for controlling apical dominance in plants, such as cutting or conventional bending, are either damaging or labor-intensive, leading to reduced growth vigor, increased resource consumption, and inefficiencies in commercial plant production.
Innovation Solution
A coiled frame with a Fibonacci or Golden Spiral design, made of wire or other materials, that allows for controlled apical growth without cutting the apical shoot, using a self-guiding mechanism to train plants by gradually bending the stem to overcome apical dominance and promote even branching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If cutting or pinching the apical shoot is used to remove apical dominance, then the time consuming aspect is reduced, but growth vigor is lost and wounds are created exposing the plant to infection
Solution Approach 1:
The patent introduces a coiled frame as an intermediary device that facilitates gradual bending of the apical shoot without direct cutting. The frame acts as a mediator between the plant and the training objective, allowing continuous gentle pressure to redirect growth while maintaining tissue integrity and preventing wounds.
Solution Approach 2:
The coiled frame provides dynamic, adjustable bending pressure that can be modified as the plant grows. Rather than static cutting, the frame allows continuous adjustment of the bending force to maintain optimal training pressure throughout the plant's growth cycle, preventing both excessive stress and insufficient training effect.
2Reliability
If conventional bending techniques are used to train plants, then apical dominance is overcome without cutting, but the process becomes much more time-consuming
Solution Approach 1:
The coiled frame is designed to be self-adjusting as the plant grows through it. The plant's own growth force interacts with the coiled structure, which automatically provides appropriate bending pressure without requiring frequent manual intervention. The system serves itself by using the plant's growth to drive the training process.
Solution Approach 2:
The coiled frame's curved, spiral structure distributes bending pressure along a gradual arc rather than applying sharp angular forces. This curved geometry allows the plant stem to bend smoothly through the coil's path, reducing stress concentration and making the bending process more efficient and less time-consuming.
3Loss of time
If the apical shoot is removed by cutting, then auxin is lost and root growth stimulation is reduced, but the plant can be trained more quickly
Solution Approach 1:
The coiled frame serves as an intermediary that redirects the apical shoot without severing it. This maintains the continuous flow of auxin from the apical meristem through the bent stem to the roots, preserving the hormone's growth-stimulating effects while still achieving the desired plant training outcome.
Solution Approach 2:
The dynamic, adjustable nature of the coiled frame allows the plant to maintain its apical shoot intact throughout the training process. The gradual bending maintains tissue continuity and auxin transport pathways, ensuring that the substance loss avoided by not cutting is preserved throughout the entire training period.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method maintains growth vigor, reduces resource consumption, and shortens the time to harvest while being efficient and cost-effective, suitable for both small and large-scale commercial applications, and allows for easy mobility of plants.
Implementation Method 1
After a growth shoot is bent it will immediately begin turning itself vertical again due to the effect of gravitropism (plant shoots display negative gravitropism; when placed on its side, a plant shoot will grow up against gravity)

AI summary
An apparatus and method for controlling apical growth of plants without cutting or pinching so as to increase productivity and efficiently utilize growth resources. A coiled frame is provided having the form of mirror image/opposed Fibonacci or Golden Spirals that expand from a first starting point and then contract back to a second starting point by an approximately similar number of quarter-turns at a selected pitch, the spring suitably being formed of a single length of wire. The apical growth tip of the plant is bent to meet the frame at selected locations and attached progressively as growth proceeds, using ties or other connectors. A stake inserted through the starting points of the spiral attaches the frame to the medium in which the plant is rooted. The stake is preferably angled so that the plant maximizes utilization of available light, for example, approximately 80° to the surface of the medium.
