Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distribution systems for injecting substances into eggs, such as vaccines or antibiotics, face issues with mechanical stress on flexible tubes, inefficiency with living vaccines, and high maintenance costs, particularly with peristaltic pumps and bulky individual micropumps.
Innovation Solution
A syringe pump-based distribution system with a controller and solenoid valves that connects multiple feed tubes to a discharge tube, allowing for precise dosing and independent adjustment of substance delivery to each injector, suitable for all types of substances, including living vaccines, and reducing mechanical stress on tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a peristaltic pump with flexible tubes is used to distribute substance to injectors, then dosing accuracy is improved, but the tubes are subject to large mechanical stresses and require frequent replacement
Solution Approach 1:
The system divides the substance distribution into multiple independent feed tubes (one per injector) instead of using a single continuous tube system. Each feed tube is short and rigid, eliminating the need for long flexible tubes that undergo mechanical stress during peristaltic pumping.
Solution Approach 2:
The patent replaces the mechanical peristaltic pumping action with a syringe-based system where substance is pushed through rigid feed tubes using a plunger. This eliminates the compression and flexing of tubes that occurs in peristaltic pumps, thereby improving tube durability while maintaining dosing accuracy through precise syringe control.
2Measurement precision
If a peristaltic pump is used for substance distribution, then dosing accuracy is improved, but the pump requires a bundle of tubes with significant length
Solution Approach 1:
The system divides the substance distribution into multiple independent feed tubes (one per injector) instead of using a single continuous tube system. Each feed tube is short and rigid, eliminating the need for long flexible tubes that undergo mechanical stress during peristaltic pumping.
Solution Approach 2:
The syringe acts as an intermediary device that receives substance from the source and distributes it through short rigid feed tubes to multiple injectors. This intermediary system eliminates the need for long flexible tubes required in direct peristaltic pump connections.
3Measurement precision
If a peristaltic pump is used to distribute substance, then dosing accuracy is improved, but living cells in vaccines are destroyed during tube compression
Solution Approach 1:
The patent replaces the mechanical peristaltic pumping action with a syringe-based system where substance is pushed through rigid feed tubes using a plunger. This eliminates the compression and flexing of tubes that occurs in peristaltic pumps, thereby improving tube durability while maintaining dosing accuracy through precise syringe control.
Solution Approach 2:
The system uses disposable syringes and rigid feed tubes that are replaced rather than continuously compressed. This eliminates the repeated mechanical stress on tubes that destroys living cells in vaccines, while maintaining dosing accuracy through precise syringe control.
4Measurement precision
If individual micropumps are used for each injector, then dosing accuracy is improved, but the system becomes bulky and expensive with high maintenance requirements
Solution Approach 1:
The patent merges multiple dosing functions into a single syringe that can serve multiple injectors through a distribution manifold. Instead of having separate micropumps for each injector, one syringe with multiple feed tubes performs the function of multiple pumps, reducing system bulk and complexity while maintaining dosing accuracy through individual valve control for each feed tube.
Solution Approach 2:
The syringe system is designed to serve multiple functions: it can distribute substance to multiple injectors, control dosing for each injector individually through valves, and adapt to different dosing requirements. This multi-functional design replaces the need for multiple specialized micropumps, reducing system complexity and cost.
