Extended-Range Spray Applicator for Avian Vaccination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray applicators for vaccines and probiotics in avian animals have limited dosing ranges, leading to uneven distribution and potential under or over-dosing, which can result in vaccination failures and side effects, and do not effectively preserve the immunogenicity of the vaccine or probiotic formulation when attempting to increase airflow for extended range.
Innovation Solution
An extended-range spray applicator that combines a spinning disc atomizer with a blower motor, allowing for the delivery of uniformly sized droplets of vaccines or probiotics over a distance of up to 10 meters, maintaining droplet size consistency and ensuring accurate dosing across a larger area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If airflow is increased to extend dosing range, then dosing distance is improved, but droplet size uniformity deteriorates and immunogenicity is lost
Solution Approach 1:
The patent segments the airflow path into distinct zones: a first airflow path for atomization and a second airflow path for droplet acceleration. This segmentation allows independent optimization of each zone - the first path maintains uniform droplet formation while the second path extends dosing distance without disrupting droplet integrity
Solution Approach 2:
The patent introduces an intermediary structure (the dual airflow path system with separate inlets and mixing chamber) that mediates between the conflicting requirements of high airflow for distance extension and controlled atomization for uniform droplet size. The intermediary allows gradual integration of airflow without direct disruption to the atomization process
2Length of moving object
If airflow is increased to extend dosing range, then dosing distance is improved, but vaccine immunogenicity deteriorates
Solution Approach 1:
The patent segments the airflow system into two distinct paths that serve different functions: one for gentle atomization that preserves vaccine integrity and immunogenicity, and another for high-velocity airflow that extends dosing distance. This segmentation prevents the harmful effects of high airflow on vaccine effectiveness while achieving the desired range extension
3Productivity
If spray coverage area is increased, then productivity is improved, but dosing uniformity deteriorates
Solution Approach 1:
The patent employs dynamic control of the dual airflow system, where the first airflow path maintains stable atomization conditions for uniform dosing, while the second airflow path dynamically accelerates droplets to extend coverage area. This dynamic approach allows the system to cover larger areas while maintaining consistent dosing uniformity across the expanded range
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 extended-range spray applicator effectively delivers vaccines or probiotics to avian animals over a wider area, ensuring uniform dosing and preserving the immunogenicity of the formulation, allowing for the vaccination or administration of 100,000 birds in 20 minutes while minimizing disturbance and side effects.
Implementation Method 1
a spinning disc atomizer, allowing for the delivery of uniformly sized droplets
Implementation Method 2
The mechanisms of sheet integration are broadly the same as those responsible for jet breakup i.e. in the case of a pressure-sprayer. If the liquid sheet is flowing at high velocity, the turbulence forces generated within the liquid may be strong enough to cause the sheet to disintegrate into groups without any aid or intervention from the surrounding air. However, the principal cause of sheet breakup stems from interaction of the sheet with the surrounding air, whereby rapidly growing waves are superimposed on the sheet. Disintegration occurs when the wave amplitude reaches a critical value and fragments of sheet are torn off. Surface tension forces cause these fragments to contract into irregular ligaments which then collapse into droplets according to the Rayleigh mechanism.
Implementation Method 3
The spraying process consists of forcing a vaccine solution through hydraulic nozzles using determined pressure, which provides the energy that breaks a stream of water into droplets.
