Disposable Brewing Cup With Barrier-Guided Clean Pouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable brewing devices face issues with aroma material and un-brewed liquid mixing with the brewed product during pouring, leading to reduced quality and increased risk of contamination, as well as being unsuitable for one-time use due to the need for cleaning and high costs.
Innovation Solution
A disposable brewing device with an inner compartment made of liquid-permeable material and an outer compartment made of liquid-impermeable material, featuring a liquid-impermeable barrier between the inner and outer compartments to prevent aroma material and un-brewed liquid from mixing with the brewed liquid during pouring, and a compact design that allows for easy use and disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter device is placed in front of the exit opening to filter aroma material, then the aroma material is filtered out before coffee leaves the brewing device, but the ground coffee will partly block the filter device making it difficult to pour coffee
Solution Approach 1:
The brewing device is divided into separate functional compartments: an inner compartment for brewing and filtration, and an outer compartment for pouring. The liquid-impermeable barrier further segments the path of the brewed liquid, directing it away from the aroma material while maintaining filtration effectiveness without blocking the pour spout.
Solution Approach 2:
A liquid-impermeable barrier is introduced as an intermediary element between the inner compartment containing aroma material and the exit opening. This barrier prevents direct contact between the brewed liquid and aroma material during pouring, ensuring filtration effectiveness while maintaining smooth pouring flow through the outer compartment's pour spout.
2Productivity
If the brewing device is tilted to pour the brewed liquid out or moved about to get out everything in one pour, then the pouring process is completed faster, but the non-filtered aroma material may still pass the barrier and mix with the filtered liquid being poured out
Solution Approach 1:
The device structure segments the brewing and pouring functions into separate compartments with a liquid-impermeable barrier. This segmentation ensures that even when the device is tilted for rapid pouring, the aroma material remains confined to the inner compartment while the filtered liquid flows through the outer compartment's pour spout, maintaining filtration reliability during fast pouring.
Solution Approach 2:
The liquid-impermeable barrier creates a three-dimensional separation between the aroma material and the liquid flow path. By positioning the barrier along the side wall of the inner compartment rather than directly in the pour path, the design allows rapid pouring through the outer compartment while the barrier prevents aroma material from migrating to the pour path even during tilted pouring.
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
Ensures the quality of the brewed product by preventing aroma material and un-brewed liquid from mixing with the brewed liquid, facilitating safe and easy pouring, and providing a cost-effective, single-use solution.
Implementation Method 1
the inner compartment is formed at least partly by a liquid-permeable material
Implementation Method 2
a liquid-impermeable barrier is arranged between the at least one inner compartment and the exit opening to substantially block the aroma material and liquid in the inner compartment from passing directly from the at least one inner compartment and out through the exit opening

AI summary
A disposable brewing device including an inner compartment formed at least partly by a liquid-permeable material and having an entrance opening for introducing liquid into said brewing device, the disposable brewing device also including aroma material contained within the inner compartment and an outer compartment forming a brewing container, where the brewing container is formed by a liquid-impermeable material, where the inner compartment is integrated within the outer compartment and the outer compartment further includes a discharge arrangement including an exit opening through which the liquid exits the brewing device, where a liquid-impermeable barrier is arranged between the at least one inner compartment and the exit opening substantially blocks the aroma material and liquid in the inner compartment from passing directly from the at least one inner compartment and out through the exit opening, when the liquid is poured out of the exit opening.
