Oscillating Deflector Nebuliser for Deep Tree Canopy Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nebuliser devices for agricultural crop fumigation struggle to penetrate tree leaves, particularly in leafy trees, as they act as a screen for the air current, preventing the nebulised product from reaching the innermost parts of the trees, and face issues with stability, sturdiness, and weight due to constant air current force.
Innovation Solution
A nebuliser system with fixed turbines and radial deflectors, featuring an external oscillating deflector that changes the direction and intensity of the air current by adjusting the outlet opening, preventing leaf screens and allowing deeper penetration of the product, while improving stability through a fixed assembly design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed deflector system is used to direct air current radially, then the nebuliser structure is simple and stable, but the air current cannot penetrate through tree leaves to reach inner parts
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed deflector system into an oscillating deflector system. The deflector is mounted on an oscillating mechanism that periodically changes the direction of the air current, enabling it to penetrate through tree leaves and reach inner parts. This dynamic adjustment allows the air current to vary its direction and intensity, solving the penetration problem while maintaining operational simplicity.
2Ease of operation
If the air current force is increased to penetrate leaves, then penetration improves, but the stability and sturdiness of the nebuliser assembly deteriorates
Solution Approach 1:
The oscillating deflector system dynamically varies the air current force rather than maintaining a constant high force. By periodically adjusting the deflector position, the system achieves leaf penetration through directional changes and intermittent force application, rather than continuous high-force application that would compromise assembly stability.
3Ease of operation
If the air current direction is changed to sweep leaves, then penetration improves, but the device complexity increases due to additional moving parts
Solution Approach 1:
The patent implements a relatively simple oscillating mechanism that provides the necessary directional changes to the air current. The oscillation creates a sweeping effect that moves leaves aside, allowing penetration. The mechanism is designed to be as simple as possible while achieving the required functional complexity for leaf sweeping and penetration.
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
The oscillating deflector system ensures the nebulised product reaches the innermost tree parts by varying the air current direction and intensity, enhancing penetration and stability of the nebuliser assembly.
Implementation Method 1
one or two turbines provided with various means for directing the air current generated
Implementation Method 2
an oscillating deflector external to said turbines which, by oscillating about its vertical axis, forces the direction of the ejected air current and alters its force by changing the outlet opening

AI summary
Improved nebuliser of the type that use an air current generated, for example, by one or two turbines to dispense the substance to be nebulised, characterised in that it has an oscillating deflector installed at a certain distance from the turbine that can alter the direction of the air current such that, while this current disseminates the product, a sweeping effect is generated that moves the leaves of trees to allow the product to reach the inner parts of the trees, said deflector comprising a laminar piece with an adequate size and shape that pivots about its vertical axis, as well as means for forcing and controlling said oscillatory motion.
