Nested Cup Beverage Filtration With Back-Pressure Brewing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current brewing and infusing methods for beverages like coffee and tea are inconvenient, messy, and lack proper insulation, with a need for separate preparation and drinking devices, and fail to effectively filter out flavoring solids while allowing lipid passage.
Innovation Solution
A nested cup system where an inner cup with a filter is inserted into an outer cup to separate brewed coffee or tea from grounds, using back pressure to prevent further filtration once fully inserted, allowing for convenient brewing and drinking from a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a filter with small holes is used to remove solid particles from beverage, then filtration effectiveness is improved, but back pressure increases and prevents further filtration
Solution Approach 1:
The filter is designed with movable components that dynamically adjust the filtration process. The inner cup can be pressed against the filter to overcome back pressure temporarily for effective filtration, then released to allow back pressure to prevent over-filtration and maintain optimal brewing conditions
Solution Approach 2:
The system changes the pressure parameter dynamically during the brewing process. By allowing the user to press the inner cup against the filter, the pressure is temporarily increased to overcome back pressure and achieve effective filtration, then the pressure is released to maintain optimal brewing parameters
2Reliability
If separate preparation and drinking devices are used, then brewing control is improved, but device complexity and inconvenience increase
Solution Approach 1:
The invention merges the preparation device (outer cup with filter) and drinking device (inner cup) into a single integrated system. The inner cup nests within the outer cup, combining brewing and drinking functions while maintaining separate control over the filtration process through the movable inner cup design
Solution Approach 2:
The inner cup nests within the outer cup, creating a compact integrated system that combines preparation and drinking functions. This nesting arrangement reduces overall device complexity while maintaining the benefits of separate brewing control and convenient drinking
3Productivity
If the inner cup is pressed into the outer cup to overcome back pressure, then filtration is achieved, but the filtering system may become stuck
Solution Approach 1:
The filtration process uses periodic action where the inner cup is pressed against the filter to overcome back pressure and achieve effective filtration, then released to allow the system to reset. This periodic pressing and releasing prevents the system from becoming stuck while maintaining high filtration productivity
Solution Approach 2:
The design anticipates the sticking problem by incorporating a release mechanism that prevents the inner cup from becoming permanently stuck against the filter. The preliminary design includes features that allow easy release after filtration, counteracting the potential harmful effect of the cup becoming stuck
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
Enables efficient filtration of beverages, maintaining flavor and preventing bitterness, while providing insulation to keep beverages at optimal temperature, thus enhancing user convenience and beverage quality.
Implementation Method 1
The small holes of a filter create friction on fluid moving through it. This results in back pressure of the filter.
Implementation Method 2
providing insulation to keep beverages at optimal temperature

AI summary
A beverage filtering device wherein flavoring solids, such as coffee, tea, or herbs, are infused or brewed with fluids and then a finished beverage is filtered from the flavoring solids using a system of nested cups. The nested cups are pressed together during filtration to create a compact form that can serve as a beverage cup or beverage serving device.
