Single-Serve Coffee Pod Grinding Whole Beans Before Brewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee making appliances either require pre-ground coffee or whole beans to be ground within the machine, which may not preserve the freshness of coffee beans and lack convenience in brewing from a single-serving package.
Innovation Solution
A coffee making appliance and method that uses a pre-packaged, disposable container with whole coffee beans, where the beans are ground in the container by a blade assembly before brewing, allowing for immediate use of fresh coffee grounds and a convenient single-serving brewing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-ground coffee is used in conventional appliances, then brewing is convenient and quick, but coffee freshness is lost and flavor quality deteriorates
Solution Approach 1:
The coffee beans are pre-packaged in a sealed container before use. This preliminary packaging action preserves the beans in whole form until the moment of brewing, preventing premature exposure to air and maintaining freshness while still allowing for convenient single-serving preparation.
Solution Approach 2:
The grinding function is extracted from the main appliance body and integrated directly into the dispensing mechanism. This allows the grinding action to occur at the point of use, right before the coffee is dispensed, ensuring that beans are ground only when needed and maintaining freshness while preserving operational convenience.
2Reliability
If whole coffee beans are ground within the machine, then coffee freshness is preserved, but the machine complexity increases and requires additional mechanisms
Solution Approach 1:
The grinding mechanism is merged with the dispensing mechanism into a single integrated unit. This combination eliminates the need for separate grinding and dispensing systems, reducing overall machine complexity while still providing the benefit of on-demand grinding for fresh coffee preparation.
Solution Approach 2:
The system is designed to accept pre-packaged containers that already contain whole beans, eliminating the need for users to manually measure or prepare coffee. The machine automatically handles the grinding and dispensing processes, simplifying operation while maintaining freshness through integrated on-demand grinding.
3Ease of operation
If pre-packaged pods with ground coffee are used, then single-serving convenience is achieved, but coffee quality deteriorates due to pre-ground status
Solution Approach 1:
Coffee beans are pre-packaged in sealed containers in whole form before use. This preliminary packaging preserves freshness while the container is designed for single-serving convenience. The whole beans remain protected until the moment of dispensing, combining the benefits of pre-packaging convenience with fresh coffee quality.
Solution Approach 2:
The system changes the physical state of coffee from pre-ground to whole beans at the point of use. By maintaining beans in whole form until dispensing and only grinding them immediately before use, the system transforms the coffee parameter from ground state to whole state, preserving quality while maintaining single-serving convenience through pre-packaged containers.
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 fresh coffee from whole beans within a single-serving package, ensuring optimal flavor and convenience by grinding the beans just before brewing, while maintaining the freshness of the coffee.
Implementation Method 1
a blade assembly punctures the foil and enters the cup, and then grinds the beans while they are still in the cup
Implementation Method 2
heated water is delivered to the cup and passes through the grounds, causing brewed coffee to emit from the opening in the bottom of the cup
Implementation Method 3
A paper filter is located on the floor of the cup and on top of the paper filter is a screen

AI summary
A brewed beverage appliance uses a specialized pre-packaged beverage container and a related method of brewing a beverage. The container comprises a cup- shaped base having openings at the bottom. A plurality of roasted, whole coffee beans are contained therein. The appliance has a blade that punctures the cup and then grinds the beans while they are still in the cup. Heated water is delivered to the cup and passes through the ground coffee causing brewed coffee to emit from the openings in the bottom of the cup and into a container such as a coffee mug.
