Mixing chamber for beverage machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for carbonating liquids, such as carbonated beverages, often require high pressures and specialized equipment, making them inefficient and inconvenient for home use, and struggle to achieve high carbonation levels quickly and reliably.
Innovation Solution
A beverage making system that uses a cartridge-based approach with a gas source, such as zeolite charged with carbon dioxide, which is activated by a precursor liquid to generate carbon dioxide, allowing for controlled carbonation of beverages with a mixing chamber design that prevents premature mixing of precursor liquid with the beverage medium, enabling rapid production of highly carbonated beverages at lower pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high pressure is used to carbonate liquids, then carbonation level is improved, but equipment complexity and safety requirements increase
Solution Approach 1:
The patent changes the pressure parameter from high (conventional) to low (below 80 psi), and changes the carbonation mechanism from direct pressure dissolution to chemical generation using zeolite. This allows achieving high carbonation levels without requiring high-pressure equipment, thereby reducing device complexity and safety requirements while maintaining effective carbonation.
Solution Approach 2:
The patent replaces the mechanical high-pressure carbonation system with a chemical system using zeolite that generates carbon dioxide in situ. This substitution eliminates the need for complex high-pressure pumps, regulators, and safety valves, achieving carbonation through chemical reaction rather than mechanical pressure application.
2Quantity of substance
If conventional carbonation equipment is used, then carbonation capability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent segments the carbonation system into separate functional modules: a zeolite cartridge containing the carbon dioxide source, a beverage medium chamber, and a mixing chamber. This modular design allows users to simply replace cartridges rather than maintain complex equipment, significantly improving ease of operation while maintaining effective carbonation capability.
Solution Approach 2:
The zeolite cartridge automatically generates carbon dioxide when activated by precursor liquid, eliminating the need for external power sources, pressure regulators, or complex control systems. The system performs carbonation through self-contained chemical reactions, making it extremely easy to operate - users only need to add water and wait for the chemical process to occur.
3Productivity
If mixing chamber allows free flow, then mixing efficiency is improved, but beverage medium loss increases
Solution Approach 1:
The patent applies preliminary action by pressurizing the beverage medium in the beverage medium chamber before mixing. This pre-pressurization creates a pressure differential that controls the flow of beverage medium into the mixing chamber, ensuring efficient mixing while preventing excessive loss. The beverage medium is ready to mix but only flows when the pressure conditions are right.
Solution Approach 2:
The patent implements dynamic flow control where the mixing chamber allows free flow when beverage medium is present (maintaining mixing efficiency) but prevents precursor liquid from flowing back when beverage medium is depleted (preventing loss). The system adapts its flow characteristics based on the presence or absence of beverage medium, optimizing both mixing efficiency and substance conservation.

AI summary
A beverage making machine may employ a mixing chamber to mix a beverage medium with a precursor liquid, such as carbonated water. The mixing chamber may have a precursor liquid inlet coupled to a precursor liquid supply, a beverage medium chamber to receive a beverage medium into the beverage medium chamber, and a dispense outlet from which beverage medium and precursor liquid are dispensed, e.g., into a user's cup. The beverage medium chamber may include a chamber inlet coupled to the precursor liquid inlet, e.g., so precursor liquid can enter the chamber when a pressure is low in the beverage medium chamber, and a chamber outlet downstream of the chamber inlet that is coupled to the dispense outlet, e.g., so that beverage medium can exit the chamber.
