Reusable Brew Chamber Filtration for Cartridge-Free Beverage Brewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single-serve beverage brewers rely on disposable cartridges, limiting beverage selection and causing unnecessary waste, as consumers are restricted to available cartridges and must discard them after use.
Innovation Solution
A reusable beverage brewing device with a cup-shaped body, filter, and adjustable outlet probe receptacles that can be used with any dry beverage medium, allowing for multiple uses and compatibility with various brewers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable beverage cartridges are used, then beverage brewing is simplified and reliable, but beverage selection is limited and waste is generated
Solution Approach 1:
The brewing system is divided into a reusable brewing device and disposable beverage containers. The brewing device contains reusable components (body, filter, outlet probe receptacle) while the beverage container holds the consumable medium. This segmentation allows the brewing mechanism to be reused with different beverage types, resolving the contradiction between brewing reliability and beverage selection versatility.
Solution Approach 2:
The brewing device is designed with universal compatibility features including a standardized outlet probe receptacle that accepts various outlet probe configurations and a filter system that works with different dry beverage mediums. This multi-functionality enables the same device to brew multiple beverage types (coffee, tea, etc.), eliminating the limitation of single-use cartridges while maintaining reliable brewing performance.
2Ease of operation
If disposable cartridges are used, then ease of operation is improved, but waste and environmental impact increase
Solution Approach 1:
Instead of discarding the entire brewing assembly after each use, the system recovers and reuses the brewing device body, filter, and outlet probe receptacle. Only the beverage container and spent beverage medium are discarded. This selective recovery and reuse of components significantly reduces material waste while maintaining operational simplicity, as the reusable components are designed for easy cleaning and repeated use.
3Adaptability or versatility
If a reusable filter system is implemented, then adaptability to different beverage mediums is improved, but device complexity increases
Solution Approach 1:
The filter is constructed from porous material that provides universal filtration capability across different dry beverage mediums (coffee grounds, tea leaves, etc.). The porous structure naturally adapts to various particle sizes and compositions without requiring complex adjustable mechanisms. This approach achieves high adaptability to different beverage mediums while keeping the device structure relatively simple, avoiding the need for complex control systems or multiple specialized filters.
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 flexible selection of beverage types, reduces waste by allowing reuse of the device, and provides a larger brew chamber for stronger or more extensive brewing, while ensuring easy cleaning and efficient extraction.
Implementation Method 1
At least one filter is defined within in the body, wherein the filter is configured to retain a dry beverage medium within the brew chamber while allowing a brewed beverage to pass through the brew chamber

AI summary
The beverage brewing device, which is configured for use with a beverage brewer having an inlet probe for dispensing water and an outlet probe, includes a body defining a brew chamber configured to contain a dry beverage medium and at least one outlet probe receptacle extending upwardly from a bottom surface of the body. The outlet probe receptacle is sized and configured to receive an outlet probe of a beverage brewer. A lid is removably securable to the body and is engageable with the body to selectively enclose a top opening of the body. An inlet probe opening is defined in the lid for receiving an inlet probe of the beverage brewer. At least one filter is defined within in the body, wherein the filter is configured to retain a dry beverage medium within the brew chamber while allowing a brewed beverage to pass through the brew chamber.
