Disposable Brewing Container With Integrated Filter for Gravity Brewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee brewing solutions require expensive equipment, are not suitable for one-time use, and often necessitate pressurized liquids or complex manufacturing processes, making them unsuitable for cost-effective, handheld brewing without specialized machinery.
Innovation Solution
A disposable brewing device comprising a liquid-permeable inner compartment integrated within a liquid-impermeable outer compartment, formed from materials like film or foil, which allows brewing under atmospheric pressure without additional equipment, reducing manufacturing costs and eliminating the need for specialized gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coffee maker with cleaning requirement is used, then brewing quality is maintained, but device complexity and cost increase
Solution Approach 1:
The patent applies a disposable brewing device that is discarded after single use, eliminating the need for cleaning and maintenance. The device includes a disposable filter element and container that are thrown away after brewing, replacing the need for permanent coffee makers that require cleaning and upkeep.
Solution Approach 2:
The brewing function is extracted from complex permanent equipment and placed into a simple disposable unit. The essential brewing components (filter, container, brewing chamber) are separated from the complex coffee maker body, allowing the brewing function to be performed independently without requiring the complex equipment.
2Productivity
If pressurized liquid is introduced through web material, then beverage extraction is achieved, but device complexity and specialized equipment requirement increase
Solution Approach 1:
The brewing device is designed to be self-activating through simple user actions. When water is poured into the container, gravity naturally causes the water to flow through the filter element and brew the beverage, eliminating the need for pressurized liquid introduction systems or specialized equipment.
Solution Approach 2:
The patent replaces complex pressurized liquid introduction mechanisms with simple gravity-driven flow. Instead of requiring pumps, pressure regulators, or specialized brewing equipment, the device uses natural gravity to move water through the filter and brew the beverage.
3Adaptability or versatility
If foldable funnel frame is used, then brewing versatility is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the funnel structure with the filter element into a single integrated component. The filter element serves dual purposes as both the filtration medium and the funnel shape, eliminating the need for separate funnel frames and simplifying the manufacturing process.
Solution Approach 2:
The disposable brewing device is designed to work with any standard cup or container, providing universal versatility. The simple open-top container design allows the device to be used with various cup types without requiring specialized brewing equipment or complex adaptive mechanisms.
4Object-affected harmful factors
If separate outer sealing is added, then aroma protection is improved, but device complexity and material consumption increase
Solution Approach 1:
The patent merges the outer sealing function with the container wall itself. The container is designed with a sealed structure that inherently protects the aroma material, eliminating the need for separate sealing layers or additional protective wrapping.
Solution Approach 2:
The container wall serves multiple functions simultaneously: it provides structural support, contains the beverage, and acts as the protective sealing barrier. This multi-functionality eliminates the need for separate sealing components and reduces overall material consumption.
