Beverage Capsule Filtration Wall for Low-Turbidity Brewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capsules for brewing tea in beverage machines are complex and expensive to produce, leading to issues with beverage quality, turbidity, taste cross-contamination, and hygiene, while also being difficult to handle and manufacture.
Innovation Solution
A capsule design featuring integral filtering means with an overflow wall and studs that act as a siphon to filter and direct the brewing liquid, allowing for a simpler and cost-effective production process while maintaining high beverage quality and reducing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a capsule comprises separate filtering wall and overflow wall with interstitial space, then beverage quality is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the filtering wall and overflow wall into a single integral structure where the filtering means is formed as part of the overflow wall itself. This merging eliminates the need for separate components and interstitial spaces while maintaining the dual functions of filtration and overflow control, thereby reducing device complexity and manufacturing cost without compromising beverage quality
2Area of stationary object
If filtering wall extends from bottom to top of enclosure, then filtering surface area increases and brewing pressure decreases, but device complexity increases
Solution Approach 1:
The filtering means is integrated directly into the overflow wall structure, creating a combined component that provides both overflow control and filtration functions. This integration achieves the necessary filtering surface area without requiring a separate full-height filtering wall, thereby reducing structural complexity while maintaining effective filtration and appropriate brewing pressure
3Quantity of substance
If overflow aperture is positioned close to top of brewing enclosure, then beverage concentration is improved, but manufacturing precision requirements increase
Solution Approach 1:
The overflow aperture is formed as an integral feature of the overflow wall structure, which is manufactured as a single piece with the filtering means. This integration ensures precise positioning of the aperture relative to the filtering surface without requiring separate assembly steps or complex positioning tolerances, thereby achieving the necessary beverage concentration while reducing manufacturing precision requirements compared to separate components
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 capsule design improves beverage concentration, reduces turbidity, and enhances brewing efficiency by ensuring full ingredient interaction with the brewing fluid, while being easier to produce and handle, and minimizes taste cross-contamination and hygiene issues.
Implementation Method 1
a brewing fluid is made to flow through the brewing enclosure
Implementation Method 2
filtering means delimiting at least one filtering side of the enclosure
Implementation Method 3
an overflow wall is positioned in the path of the brewed liquid after the filtering means and comprises at least one overflow aperture
