Stand-up Pouch Dosing System for Settling Fluids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metering devices for liquid media, especially those prone to settling, face issues such as simultaneous dosing limitations, fluid loss due to evaporation, contamination risks, and frequent maintenance needs, including clogging and replacement of components, which lead to inconsistent product compositions and waste.
Innovation Solution
A stand-up pouch with two connections arranged vertically, integrated into a container system that allows for closed-circuit homogenization without agitators, combined with a vacuum sensor and buffer container for efficient residual emptying, enabling maximum emptying and sterile conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional open storage containers are used for liquid media, then filling and access are simplified, but fluid loss due to evaporation occurs and contamination risks increase
Solution Approach 1:
The patent uses a flexible pouch made of laminated film material to replace conventional open storage containers. The pouch is sealed to prevent evaporation and contamination while maintaining ease of filling through its integration into the dosing device. The flexible nature allows the pouch to be refilled by replacing the entire unit, combining the benefits of sealed containment with operational simplicity.
2Stability of the object's composition
If mechanical agitators are used in storage containers to prevent settling, then homogeneity is maintained, but device complexity and maintenance needs increase
Solution Approach 1:
The patent removes the mechanical agitator from the storage container and relocates the mixing function to the dosing template. The dosing template includes a mixing chamber where liquid media is mixed with solid particles during the dosing process itself, rather than requiring continuous agitation during storage. This eliminates the complex mechanical agitator mechanism while maintaining homogeneity when needed.
3Device complexity
If sequential dosing of individual components is used, then device complexity is reduced, but productivity decreases
Solution Approach 1:
The patent combines multiple dosing functions into a single integrated dosing template. The dosing template can simultaneously dose multiple liquid media and mix them with solid particles in one operation, rather than requiring separate sequential dosing steps. This merging of functions increases productivity while maintaining manageable device complexity through modular design.
4Adaptability or versatility
If storage containers are filled from outside, then filling flexibility is improved, but contamination risks and product consistency issues increase
Solution Approach 1:
The patent employs disposable sealed pouches that are pre-filled with liquid media. Each pouch is hermetically sealed to prevent contamination and maintain consistent product composition. When the pouch is emptied, it is replaced with a new pre-filled pouch, ensuring consistent quality without the risks associated with external filling operations. The pouch integrates into the dosing device, maintaining filling flexibility through easy replacement.
