Coffee Filter Assembly with Multi-Zone Filtration and Brew Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee filters do not effectively filter out particulates of varying sizes, and there is a need for devices that allow consumers to easily view the filtered beverage level while brewing.
Innovation Solution
A filter assembly comprising a filter member with adjustable through-holes, a receptacle, and a flange that secures the assembly to a container, allowing for adjustable filtration based on particulate size and providing visibility into the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing coffee filters use fixed-size filtration openings, then the filter structure is simple, but it cannot effectively filter out particulates of varying sizes
Solution Approach 1:
The filter member is divided into multiple zones with different opening sizes (first plurality of openings and second plurality of openings). This segmentation allows each zone to handle different particle sizes, improving filtration precision for varying particulates while maintaining a relatively simple overall filter structure.
Solution Approach 2:
Different regions of the filter member are given different filtration properties through varying opening sizes. The first plurality of openings has different dimensions than the second plurality, creating local quality variations that optimize filtration for different particle sizes across different areas of the filter.
2Ease of operation
If the filter assembly is designed to be opaque, then the structure is simpler, but users cannot view the filtered beverage level during brewing
Solution Approach 1:
The filter assembly incorporates a transparent or translucent portion that allows dynamic visual monitoring of the brewing process. This enables users to observe the filtered beverage level in real-time without requiring the entire assembly to be complex, balancing transparency needs with structural simplicity.
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
Effectively filters particulates of specific sizes and allows users to monitor the brewing process by viewing the filtered liquid level within the container.
Implementation Method 1
the filter member has a plurality of through-holes configured to allow the liquid to pass therethrough but to prevent those of the particulates that are larger than a predetermined size from passing through the plurality of through-holes

AI summary
A filter assembly that includes a receptacle, filter, and filter holder. The receptacle has an inside surface defining an open-ended first through-channel. The filter is positioned inside the first through-channel and configured to produce a filtered liquid by filtering particulates each larger than a predetermined size from a liquid. The filtered liquid exits the filter through an outlet opening of the filter. The filter holder removably couples the filter to the receptacle. A holding area configured to receive the liquid is defined in the first through-channel above the filter holder and between the filter and the inside surface of the receptacle. The filter holder includes an open-ended second through-channel in fluid communication with the outlet opening and configured to receive the filtered liquid from the outlet opening. The second through-channel is configured to be in fluid communication with an interior of a container and to provide the filtered liquid thereto.
