Solution Overview
Problem
Existing beverage making cartridges fail to control the flow rate and pattern of pressurized fluid effectively, leading to incomplete extraction of the beverage medium and waste, as the permeability of the filter is uniform, causing the fluid to flow too quickly and unevenly, resulting in a weak beverage.
Innovation Solution
A cartridge design with a filter material that includes a coating to reduce permeability at specific areas, controlling the flow rate and pattern by applying the coating in predetermined patterns, and incorporating supplements such as flavorings or nutrative compounds that can be dissolved or dispersed in the fluid, ensuring adequate extraction of the beverage medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the filter material has uniform permeability, then the manufacturing is simple, but the fluid flows too quickly and unevenly through the filter, resulting in incomplete extraction of the beverage medium
Solution Approach 1:
The filter material is provided with a coating on specific portions to create zones of different permeability. This allows different areas of the filter to have different flow resistance, controlling the fluid flow pattern to ensure complete contact with the beverage medium while maintaining manufacturing simplicity through selective coating application.
2Speed
If the filter permeability is high, then the fluid flows quickly through the cartridge, but the contact time between pressurized liquid and beverage medium is insufficient, leading to weak beverage extraction
Solution Approach 1:
By applying coating to specific portions of the filter material, the invention creates a flow control pattern that maintains high overall flow rate while extending fluid contact time with the beverage medium in uncoated areas. The coating acts as a flow regulator rather than a complete barrier, optimizing both speed and duration of extraction.
3Productivity
If the filter material allows rapid fluid flow, then the beverage making process is fast, but the pressurized liquid does not extract the entirety of the beverage medium, resulting in wasted beverage medium
Solution Approach 1:
The selective coating pattern on the filter material creates zones that direct and extend fluid flow paths through the beverage medium. This ensures complete extraction of the beverage medium by forcing the fluid to contact all areas, while maintaining rapid overall flow rate to preserve beverage making speed.
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 controlled flow rate and pattern of the pressurized fluid enhance the extraction of the beverage medium, resulting in a stronger final product with reduced waste and improved extraction efficiency.
Implementation Method 1
a coating arranged on at least one portion of the filter material, wherein the coating decreases the permeability of the filter material at the at least one portion of the filter material

AI summary
The technology relates to a beverage cartridge. The beverage cartridge may comprise a filter, an enclosure, a coating, and a supplement. The filter may have a predetermined permeability to permit a fluid to flow therethrough. The enclosure may at least substantially surrounding said filter. The coating may be arranged on at least one predetermined portion of the filter, wherein the coating decreases the permeability of the filter to control the flow of the fluid therethrough. The supplement may be arranged on the filter, the supplement adapted to be dissolved or dispersed in the fluid.
