Disposable Brewing Pouch Barrier Layout for 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 difficulties in pouring due to blockages and leakage.
Innovation Solution
A disposable brewing device with a liquid-impermeable barrier formed by welding between the inner and outer compartments, positioned to prevent direct passage between the inner compartment and the exit opening, ensuring controlled pouring and maintaining the quality of the brewed liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter device is placed in front of the exit opening to filter aroma material, then aroma material can be filtered out, but the ground coffee will block the filter device making it difficult to pour coffee
Solution Approach 1:
The brewing device is divided into separate functional zones: an inner compartment for brewing, an outer compartment for discharge, and a barrier structure with opening separating them. This segmentation allows the barrier opening to control liquid flow while the filter device remains in its optimal position for filtration without blocking the exit.
2Productivity
If the inner compartment is positioned directly above the exit opening for efficient draining, then pouring efficiency is improved, but aroma material and un-brewed liquid can pass directly from the inner compartment to the exit opening
Solution Approach 1:
The discharge path is segmented into two separate compartments - the inner compartment for brewing and the outer compartment for discharge. The barrier structure with opening connects these compartments, allowing efficient draining while preventing direct passage of aroma material and un-brewed liquid to the exit opening.
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 solution effectively prevents aroma material and un-brewed liquid from mixing with the brewed liquid, ensuring a higher quality product and easy, controlled pouring, while also being cost-effective and simple to manufacture.
Implementation Method 1
a welding between said discharge arrangement and at least one of said at least one inner compartment

AI summary
Disclosed is a disposable brewing device (1)comprising at least one inner compartment (2), wherein the inner compartment (2)is formed at least partly by a liquid-permeable material and comprising an entrance opening (3)for introducing liquid into said brewing device (1). The disposable brewing device (1)also comprises aroma material (4)being contained within the at least one inner compartment (2)and at least one outer compartment (5)forming a brewing container (6), wherein the brewing container (6)is formed by a liquid-impermeable material. The at least one inner compartment (2)is integrated within the outer compartment (5) and the outer compartment (5)further comprises a discharge arrangement (7) including an exit opening (8)through which the liquid exits the brewing device (1), wherein a liquid-impermeable barrier (9)is arranged between the at least one inner compartment (2)and the exit opening (8)to substantially block the aroma material (4)and liquid in the inner compartment (2)from passing directly from the at least one inner compartment (2) and out through the exit opening (8), when the liquid is poured out of the exit opening (8).
