Single-Serve Bean Pod Brewing With Integrated Grinding and Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee brewing appliances either require pre-ground coffee or whole beans to be ground within the machine, which may not preserve the freshness of coffee and can be inconvenient, especially when using pre-packaged coffee grounds that need separate filtering mechanisms.
Innovation Solution
A beverage appliance with a housing, liquid reservoir, and a grinding mechanism that accommodates a disposable, pre-packaged filter cup containing whole coffee beans, where the beans are ground immediately before brewing, and the brewed coffee is collected through a filtering mechanism within the cup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-packaged coffee grounds are used in separate filter containers, then brewing convenience is improved, but coffee freshness is lost due to pre-grinding
Solution Approach 1:
The beverage container is divided into separate compartments: a storage area for whole coffee beans and a brewing area with filter. The grinding mechanism is integrated into the appliance rather than the container, allowing whole beans to be stored separately from the brewing process, thus maintaining freshness while enabling convenience.
Solution Approach 2:
Whole coffee beans are pre-packaged in the container before use, rather than pre-grinding them. The grinding action is performed immediately before brewing through the integrated grinding mechanism, preserving freshness while maintaining the convenience of pre-packaging.
2Reliability
If whole coffee beans are ground immediately before brewing, then coffee freshness is improved, but device complexity increases due to integrated grinding mechanism
Solution Approach 1:
The grinding mechanism, piercing assembly, and beverage container are combined into an integrated system. The container is designed to work specifically with the grinding mechanism, merging storage, grinding, and brewing functions into a unified apparatus that maintains freshness without excessive complexity.
Solution Approach 2:
The beverage container serves multiple functions: it stores whole coffee beans, works with the piercing assembly to access the beans, and contains the brewing process with its integrated filter. This multi-functionality reduces the need for separate components, managing device complexity while achieving freshness.
3Ease of operation
If pre-packaged pods with ground coffee are used, then ease of operation is improved, but filtering mechanism complexity increases
Solution Approach 1:
The filter is integrated directly into the bottom of the beverage container rather than being a separate component. This merging of the filter with the container eliminates the need for separate filtering mechanisms, maintaining ease of operation while reducing overall system complexity.
Solution Approach 2:
The beverage container is self-contained with an integrated filter mechanism that performs the filtering function automatically during brewing. The container serves itself by incorporating the necessary filtering capability, eliminating the need for external or separate filtering 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
This solution allows for freshly ground coffee to be brewed from whole beans in a convenient, single-serving package, maintaining flavor and freshness while eliminating the need for separate filtering mechanisms, and providing a compact, disposable brewing process.
Implementation Method 1
The piercing assembly selectively pierces the fracturable seal thereby causing said beverage ingredient to enter the grinding mechanism
Implementation Method 2
the grinding mechanism selectively transforms the beverage ingredient from the first size to a second size, the second size being smaller than the first size
Implementation Method 3
The filter is positioned at a bottom of the beverage container such that the brewed coffee is filtered as it exits the beverage container

AI summary
A beverage assembly includes a housing having a liquid reservoir, an inlet portion formed in the housing, a beverage container configured to be removably accommodated within the inlet portion and having a fracturable seal and containing a beverage ingredient of a first size, a grinding mechanism positioned within the housing and in fluid communication with the inlet portion, and a piercing assembly positioned within the housing, wherein the piercing assembly selectively pierces the fracturable seal thereby causing said beverage ingredient to enter the grinding mechanism. The grinding mechanism selectively transforms the beverage ingredient from the first size to a second size, the second size being smaller than the first size. The beverage assembly further includes a brewing area disposed beneath the grinding assembly and configured to removably accommodate the beverage container after the beverage container has been pierced by the piercing assembly.
