Recirculation Loop for Uniform Vaccine Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering vaccines and medicines to animals, particularly in the poultry industry, face challenges with non-uniform delivery due to settling of particulates in solution, leading to wasteful priming of nozzles and inconsistent dosing, which can result in poor performance and outbreaks when birds are exposed to pathogens.
Innovation Solution
A system with a recirculating loop and valve control mechanism that maintains the fluid in suspension, allowing for continuous recirculation when not in use, ensuring uniform delivery without the need for repeated priming of the nozzle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the nozzle is primed to prevent non-uniform delivery, then delivery uniformity is improved, but substance waste increases and operation complexity increases
Solution Approach 1:
The system performs preliminary action by continuously recirculating the vaccine solution through the nozzle before actual delivery begins. This keeps the particulate matter suspended and prevents settling, so the nozzle is already primed and ready for uniform delivery without requiring additional priming steps that waste vaccine.
Solution Approach 2:
The recirculation system maintains continuous useful action by constantly moving the vaccine solution through the nozzle and back to the reservoir. This continuous circulation prevents particulate settling and maintains delivery uniformity throughout operation, eliminating the need for intermittent priming operations that waste substance.
2Manufacturing precision
If the nozzle is primed to prevent non-uniform delivery, then delivery uniformity is improved, but operation time increases
Solution Approach 1:
The system performs preliminary action by continuously recirculating the vaccine solution through the nozzle before actual delivery begins. This keeps the particulate matter suspended and prevents settling, so the nozzle is already primed and ready for uniform delivery without requiring additional priming steps that waste vaccine.
Solution Approach 2:
The recirculation system maintains continuous useful action by constantly moving the vaccine solution through the nozzle and back to the reservoir. This continuous circulation prevents particulate settling and maintains delivery uniformity throughout operation, eliminating the need for intermittent priming operations that waste substance.
3Use of energy by moving object
If the particulate is allowed to settle in the reservoir, then energy consumption decreases, but delivery uniformity worsens
Solution Approach 1:
The recirculation system maintains continuous useful action by constantly moving the vaccine solution through the nozzle and back to the reservoir. This continuous circulation prevents particulate settling and maintains delivery uniformity throughout operation, eliminating the need for intermittent priming operations that waste substance.
Solution Approach 2:
The system employs mechanical agitation through the recirculation flow to keep particulate matter suspended in the vaccine solution. The continuous movement created by pumping the solution through the nozzle and back prevents gravitational settling, maintaining uniform distribution without requiring excessive energy input.

AI summary
A system for delivery of a fluid to an animal is provided in the present disclosure. The system includes a reservoir to hold a volume of fluid, delivery outlet, recirculating loop, and valve in fluid communication between the reservoir and delivery outlet, the valve having an inlet to receive fluid from the reservoir, a first outlet in fluid communication with the delivery outlet, and a second outlet in fluid communication with a return conduit to the reservoir. The system further includes control means for opening and closing the first and second valve outlets, and a pump to pump fluid from the reservoir to the valve and through the reservoir return conduit to the reservoir. When the control means opens the first outlet, the fluid flows from the reservoir to the delivery outlet. When the control means opens the second valve outlet, the fluid flows through the return conduit to the reservoir.
