Solution Overview
Problem
Coffee brewing systems fail to extract full flavor from ground coffee due to loose packing, and pod adapter systems often struggle to securely hold coffee pods and puncture them consistently.
Innovation Solution
A container design with a receptacle and cover that includes a passageway for fluid communication, a filter, and a tamping mechanism to ensure proper coffee packing and water flow, preventing needle contact and enhancing flavor extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ground coffee is loosely packed in a coffee filter, then water can flow freely through the coffee, but full flavor extraction is not achieved
Solution Approach 1:
The patent applies preliminary action by tamping the coffee grounds before brewing to compact them into the filter. This pre-compression ensures that when water flows through, it maintains sufficient contact with the coffee particles for full flavor extraction while still allowing adequate flow. The tamping action is performed in advance to create the optimal density structure.
2Stability of the object's composition
If the base is placed directly on the support surface, then stability is improved, but the outflow needle may contact the base and interfere with brewing
Solution Approach 1:
The patent applies segmentation by dividing the base structure into two functional zones: a stable support footprint area and an elevated brewing area. The protrusion creates a spatial separation where the base remains stable on the support surface while the elevated portion positions the outflow needle clear of any base contact. This structural segmentation resolves the conflict between stability and needle interference.
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 container design ensures efficient fluid flow and secure coffee packing, improving flavor extraction and preventing coffee grounds from escaping during brewing.
Implementation Method 1
The passageway provides fluid communication from an interior of the receptacle to an exterior of the receptacle
Implementation Method 2
The passageway can be at least partially covered by a screen material
Implementation Method 3
a tamping mechanism to ensure proper coffee packing and water flow

AI summary
A container includes a receptacle and a cover. The receptacle includes a base and a sidewall. The base has an interior surface and a passageway in an interior area of the base. The passageway provides fluid communication from an interior of the receptacle to an exterior of the receptacle. The sidewall extends upward from the interior surface of the base. The cover is configured to sealingly engage with a top edge of the sidewall, and includes a cover opening. The container is configured to accept input fluid through the cover opening and to provide a corresponding outflow of fluid through the passageway. The passageway allows the outflow fluid to flow from the container while accommodating an outflow needle of a beverage brewer.
