Brewing Chamber Pressure Release Valve for Easy Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing beverage making devices face difficulty in easily opening the brewing chamber due to residual pressure after the water supply is terminated, caused by blockages in the orifice, which results in perceptible resistance.
Innovation Solution
Incorporating a pressure release valve in the water supply conduit that opens to a low-pressure space after water supply cessation, utilizing a moveable membrane to control flow and release pressure, ensuring the brewing chamber can be opened effortlessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the brewing chamber is sealed during brewing to maintain pressure, then the brewing process is effective, but the chamber cannot be opened easily after brewing due to residual pressure
Solution Approach 1:
The patent extracts the pressure release function from the main brewing chamber structure by introducing a separate pressure release valve. This valve can be opened independently to release residual pressure without requiring the main chamber lid to be opened, thus resolving the contradiction between maintaining sealing during brewing and enabling easy opening after brewing.
Solution Approach 2:
The pressure release valve acts as an intermediary mechanism between the sealed brewing chamber and the external environment. It provides a controlled pathway for pressure equalization, allowing the chamber to transition from a sealed high-pressure state to an openable low-pressure state without compromising the integrity of the main brewing seal.
2Ease of operation
If a pressure release valve is added to release residual pressure, then the chamber can be opened easily, but the device complexity increases
Solution Approach 1:
The patent merges the pressure release valve with the existing water supply conduit structure. The valve is integrated into the conduit that already exists in the brewing chamber, utilizing the same structural space and mounting points. This integration approach adds the pressure release function without requiring a completely separate valve assembly, thus minimizing the increase in device complexity.
Solution Approach 2:
The water supply conduit is given multiple functions: it serves both as the water supply pathway during brewing and as the housing for the pressure release valve. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while still providing the desired pressure release capability.
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 pressure release valve effectively reduces resistance when opening the brewing chamber by releasing excess pressure, ensuring smooth operation and easy access after brewing, without requiring additional openings in the chamber.
Implementation Method 1
a moveable member that can move between a first position, in which said second outlet is open, and a second position, in which said second outlet is closed, said moveable member being moved by the dynamic pressure variation of the water supplied by the pumping means

AI summary
A beverage making device comprising a brewing chamber configured to brew a beverage, the device comprising: a valve assembly comprising: a housing including an inlet for receiving pressurized water into the housing, a two way passage coupling the housing to the brewing chamber, an outlet configured to remove the brewed beverage from the housing, and a pressure release valve configured to close the outlet to send the pressurized water out of the two way passage to the brewing chamber when the pressurized water is supplied to the inlet, and close the inlet to receive a brewed beverage from the brewing through the two way passage when the pressurized water is not provided to the inlet.
