Solution Overview
Problem
Existing beverage extracting devices face issues with height constraints due to top-down design, persistent dripping after liquid extraction, and heat loss of the extracted beverage, particularly for super-hot beverages like coffee.
Innovation Solution
The device features a movable vessel that seals with the filter, allowing pressurized gas to stir the mixture from below, an outlet duct positioned above the vessel to prevent dripping without a valve, and a gas pump operation that maintains liquid temperature and flow control, along with an optional movable endless belt filter and sensors for monitoring and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the outlet duct is positioned below the filter with top-down design, then the liquid flow path is straightforward, but the device height becomes considerable and users cup must be placed below the filter
Solution Approach 1:
The patent inverts the conventional top-down design by positioning the outlet duct above the vessel instead of below. The outlet duct extends upward from the filter outlet, allowing liquid to flow upward against gravity initially, then downward into the cup. This inversion reduces the required device height while maintaining proper liquid flow control without requiring the cup to be positioned below the filter.
Solution Approach 2:
The outlet duct is positioned in a different spatial arrangement, extending upward from the filter rather than continuing downward. This changes the vertical dimension utilization, allowing the outlet to be located above the vessel while still enabling liquid delivery to a cup positioned at an appropriate height, thereby reducing overall device height requirements.
2Object-affected harmful factors
If a valve is applied to close off the outlet duct, then dripping is prevented, but the heat capacity of the valve causes the liquid to cool down
Solution Approach 1:
The patent removes the valve component from the outlet duct system entirely. Instead of using a valve to close off the outlet duct, the design relies on the outlet duct being positioned above the vessel, allowing gravity to naturally stop liquid flow when the extraction is complete. This eliminates the heat-capacity-related cooling problem while still preventing dripping through proper positioning and gravity-assisted flow control.
3Productivity
If the vessel is fixed in position, then the structure is simple, but the mixing intensity is insufficient and liquid expelling through the filter is hindered
Solution Approach 1:
The patent introduces dynamic movement to the previously static vessel. The vessel is made movable relative to the filter, enabling it to engage with the filter for sealing and disengage for removal. This dynamic arrangement improves extraction efficiency by ensuring proper sealing contact between the vessel and filter, while the movement capability also aids in liquid expelling through the filter by allowing pressure differential creation during the extraction cycle.
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
This design reduces the device's height, prevents dripping, maintains the temperature of the extracted beverage, and allows for versatile cup placement, ensuring efficient and high-quality extraction of beverages while minimizing heat loss.
Implementation Method 1
a gas pump that connects through a duct to the vessel for supplying pressurized gas into the vessel
Implementation Method 2
the duct for supplying pressurized gas into the vessel connects to a channel or channels within the vessel having outflow openings at a lower rim of the vessel to stir the mixture inside the vessel from below in an upwards direction
Implementation Method 3
the vessel is up-and-down movable so as to enable engaging a lower rim of the vessel with the filter thereby acting as a seal
Implementation Method 4
at least a portion of the outlet duct is at least in part located above the vessel. This construction avoids the necessity of applying a valve to close off the outlet duct when the extraction is completed, yet ensures that dripping of the outlet duct is prevented
