Single-Serve Coffee Pod with In-Cup Grinding and 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 and can be inconvenient, especially when seeking to brew a single serving.
Innovation Solution
A coffee making appliance and disposable, pre-packaged container with a built-in filter and screen that allows whole coffee beans to be ground immediately before brewing, using a blade assembly to grind the beans within the container, and then brews coffee using heated water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-packaged containers with ground coffee are used, then convenience is improved, but coffee freshness is degraded
Solution Approach 1:
The coffee beans are pre-packaged in a sealed container before use, preserving them in whole bean form until the moment of brewing. This preliminary preparation maintains freshness while keeping the brewing process convenient, as the user simply needs to insert the pre-packaged container into the appliance without manual grinding or preparation.
2Object-generated harmful factors
If whole coffee beans are ground immediately before brewing, then coffee freshness is improved, but device complexity is worsened
Solution Approach 1:
The grinding mechanism and brewing chamber are merged into a single integrated unit. The blade assembly is positioned within the brewing chamber so that grinding and brewing occur in the same space, eliminating the need for separate grinding and brewing components. This reduces overall device complexity while maintaining the freshness benefit of immediate grinding.
Solution Approach 2:
The blade assembly is nested within the brewing chamber, with the grinding mechanism contained inside the same space where brewing occurs. This nested arrangement allows the grinding function to be incorporated without adding external complexity to the appliance structure.
3Object-generated harmful factors
If a blade assembly is used to grind beans within the container, then coffee freshness is improved, but device complexity is worsened
Solution Approach 1:
The blade assembly serves multiple functions: it pierces the sealed container to access the coffee beans, grinds the whole beans into grounds, and may also stir the grounds during brewing. This multi-functionality reduces the need for separate components for each operation, thereby reducing device complexity while maintaining the freshness advantage of in-container grinding.
4Ease of operation
If pre-packaged containers are used, then ease of operation is improved, but adaptability is worsened
Solution Approach 1:
The coffee packaging is segmented into individual single-serving containers, each hermetically sealed to preserve freshness. This segmentation allows users to store multiple types of coffee beans (different origins, roasts, or blends) in separate containers, providing adaptability and variety while maintaining the convenience of single-serving portions. Each container can be independently selected based on the desired coffee type.
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 the brewing of fresh coffee from whole beans in a convenient, single-serving format, ensuring optimal flavor and ease of use by grinding beans just before brewing and containing the process within a sealed, disposable package.
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
Next, 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.
