Single-Serve Brew Cup Grinding for Fresh Whole-Bean Coffee
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 freshness or convenience, and often involve separate filter mechanisms or pods.
Innovation Solution
A beverage appliance that includes a housing with a liquid reservoir, a grinding mechanism, and a piercing assembly to transform whole coffee beans into grounds within a disposable, single-serving filter cup, allowing for immediate brewing with optimal flavor preservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If whole coffee beans are ground immediately before brewing, then coffee freshness and flavor are improved, but device complexity increases due to need for grinding mechanism
Solution Approach 1:
The patent employs a disposable filter cup that contains whole coffee beans and a built-in grinding blade. The entire assembly (cup + beans + blade) is discarded after single use, eliminating the need for permanent grinding mechanisms in the appliance. This resolves the contradiction by providing fresh ground coffee without requiring complex reusable grinding components.
Solution Approach 2:
The grinding function is segmented from the main appliance and integrated into the disposable filter cup itself. The filter cup is divided into functional components: container for beans, integrated grinding blade, and filtering structure. This segmentation allows the grinding capability to be temporary and disposable rather than permanent and complex.
2Ease of operation
If pre-packaged pods with ground coffee are used, then ease of operation is improved, but coffee freshness deteriorates due to pre-ground storage
Solution Approach 1:
The filter cup is pre-prepared with whole coffee beans and a grinding blade in a sealed state before use. The grinding action is performed immediately before brewing when the cup is inserted into the appliance, rather than grinding in advance during manufacturing. This preliminary preparation maintains freshness while ensuring operational convenience.
3Adaptability or versatility
If separate filter mechanisms are used, then brewing flexibility is improved, but device complexity and number of parts increases
Solution Approach 1:
The filter cup integrates multiple functions into a single component: it serves as the coffee container, holds the grinding blade, provides the filtering mechanism, and acts as the brewing chamber. The bottom of the cup itself functions as the filter with holes for water passage. This merging eliminates separate filter mechanisms and reduces overall device complexity while maintaining brewing flexibility.
Solution Approach 2:
The disposable filter cup is designed as a multi-functional element that performs storage, grinding, brewing, and filtering operations. The cup body serves multiple purposes: containing beans, supporting the grinding blade, and acting as the filter through its perforated bottom. This universality replaces multiple separate components with a single versatile unit.
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
Enables brewing of freshly ground coffee from whole beans in a convenient, disposable package, ensuring optimal flavor and ease of use while eliminating the need for separate grinding or filter mechanisms.
Implementation Method 1
A piercing assembly is positioned within the housing and is configured to pierce the fracturable seal
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
heated water is delivered to the container and passes therethrough. The container typically includes a filtering mechanism so that heated water exiting the container is in the form of brewed coffee
Implementation Method 4
The container typically includes a filtering mechanism so that heated water exiting the container is in the form of brewed coffee

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.
