Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee machines using coffee pods struggle to produce rich and fine coffee foam, as existing foaming technologies like vortex, spouting, and jet impingement methods fail to meet high quality standards due to insufficient foam generation.
Innovation Solution
A coffee machine equipped with a foaming device featuring a nozzle, coffee receiving chamber with multiple filter screens, and an exhausting exit, which employs reverse filtration technology to produce foam by passing the coffee jet through the filter screens multiple times, enhancing foam quality and flavor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional foaming technologies (vortex, spouting, jet impingement) are used individually, then the device complexity is low, but the foam quality is insufficient and does not meet high quality requirements
Solution Approach 1:
The foaming device is segmented into multiple functional components working in sequence: a nozzle for jet impingement foaming, a coffee receiving chamber with filter screens for filtration foaming, and an exhausting exit for vortex generation. Each segment performs a specific foaming function, and their combination produces rich and fine coffee foam that meets high quality requirements while maintaining reasonable device complexity through modular design
Solution Approach 2:
The patent merges three conventional foaming technologies (jet impingement, vortex, and filtration) into a single integrated foaming device. The nozzle provides jet impingement, the coffee receiving chamber with filter screens provides filtration, and the exhausting exit provides vortex generation. By combining these technologies in one device, the patent achieves high-quality foam production without significantly increasing overall device complexity
2Manufacturing precision
If filter screens are used to produce foam by allowing coffee jet to pass through, then the device structure is simple, but the foam is not rich or fine enough
Solution Approach 1:
The nozzle performs preliminary jet impingement foaming on the coffee liquid before it enters the coffee receiving chamber. This preliminary action pre-mixes the coffee with air and creates initial foam structure, which then undergoes further refinement when passing through the filter screens. This preliminary foaming action enhances the overall foam generation efficiency and produces richer, finer foam
Solution Approach 2:
The patent uses filter screens with specific mesh structures as porous materials in the coffee receiving chamber. These filter screens not only filter the coffee liquid but also generate foam by forcing the coffee jet through their porous structure. The combination of jet impingement and porous filter screen filtration creates rich and fine coffee foam, improving both foam fineness and generation efficiency
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 reverse filtration technology produces rich and fine coffee foam by utilizing vortex rotation and multiple air mixing stages, improving coffee quality and flavor by dividing larger foam into smaller, finer bubbles.
Implementation Method 1
The filter screen is provided with at least one filter screen with meshes and each filter screen is disposed with a through hole allowing the coffee ejected from the nozzle to pass through
Implementation Method 2
It carries out vortex rotation to produce more foam for the second time
Implementation Method 3
the coffee liquid passes through the filter screen on the top of the coffee receiving chamber again to fully mix with air to produce foam for the third time
