Beverage Lid Filter With Protrusion Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for preparing hot beverages on-the-go, such as 'presso' brewing, require pots and filter-plungers and suffer from filter clogging issues when using filters to separate coffee powder and water, making it difficult to drink without interruptions.
Innovation Solution
A sealing means with a liquid permeable filter featuring a protrusion for accurate and cost-efficient attachment to the annular cover portion, along with a tube for guiding the filter and allowing access for adding milk or sweeteners without removing the lid, ensuring the filter is spaced to prevent clogging and maintain a natural flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter is used to separate coffee powder and water, then coffee quality is improved, but the filter becomes clogged and flow is blocked
Solution Approach 1:
The filter is divided into multiple segments or layers with different pore sizes. The upper layers have smaller pores for fine filtration, while lower layers have larger pores to maintain flow. This segmentation allows the filter to maintain both high filtration quality and sustained liquid flow without clogging.
Solution Approach 2:
The filter structure is designed to be dynamic, allowing it to adapt during the brewing process. The filter media or structure can change properties under pressure or over time, maintaining porosity and flow characteristics even as coffee grounds are introduced, preventing complete clogging while ensuring quality separation.
2Device complexity
If a filter is positioned close to the lid for compact design, then device complexity is reduced, but the filter clogs more easily
Solution Approach 1:
Instead of positioning the filter horizontally close to the lid, the filter is oriented vertically or at an angle, utilizing the vertical dimension. This dimensional change allows the filter to be compact in the horizontal plane while maintaining sufficient vertical distance from the lid, preventing clogging while keeping the overall device complexity low.
3Manufacturing precision
If a protrusion structure is used for filter attachment, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The protrusion structure serves multiple functions simultaneously: it provides precise positioning of the filter, acts as a mounting attachment point, and may also serve as a guide for filter installation. This multi-functionality reduces the need for separate positioning and mounting features, thereby reducing overall device complexity while maintaining manufacturing precision.

AI summary
The present invention provides an improved sealing means, typically a lid, for a beverage container. Positioned, between the annular cover portion of the lid and the rim of the beverage container, is a liquid permeable filter, this filter having an opening for receiving a mounting member in the form of a protrusion, which extends from the annular cover portion, downwards, through the annular cover portion, into the beverage container, where the inner peripheral edge of the opening of the liquid permeable filter is attached around the outer periphery of the protrusion. With a protrusion in the form of a tube surrounding an opening in the annular cover portion, food additives are allowed to be inserted after the lid has been mounted to the drinking container.
