Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for carbonating liquids to make beverages often require high pressures, complex setups, and can be messy, failing to efficiently produce highly carbonated beverages in a convenient and cost-effective manner.
Innovation Solution
A beverage making system that uses cartridges containing a carbon dioxide source, such as charged zeolite, and a beverage medium, which are integrated into a cartridge chamber to carbonate and mix liquids efficiently, allowing for controlled carbon dioxide production and mixing, reducing the need for high pressures and complex equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing carbonation systems are used, then carbonation can be achieved, but high pressures and complex setups are required
Solution Approach 1:
The system divides the carbonation function into separate cartridges containing carbonation agents (such as sodium bicarbonate and citric acid) that can be independently replaced. This segmentation allows the main carbonation chamber and control system to remain simple while the consumable cartridges handle the complex chemical reactions, resolving the contradiction between reliable carbonation and system complexity.
Solution Approach 2:
The patent employs disposable cartridges containing pre-measured carbonation agents that are replaced after use. These inexpensive, single-use cartridges eliminate the need for complex cleaning, maintenance, and calibration systems, achieving reliable carbonation without requiring complex permanent infrastructure.
2Reliability
If existing carbonation systems are used, then carbonation can be achieved, but the systems can be messy
Solution Approach 1:
By separating the carbonation chemicals into enclosed cartridges, the system contains all potential mess (powder spills, liquid splashes, foam overflow) within the cartridge boundaries during insertion and operation. The cartridges are designed to seal properly and release contents in a controlled manner, eliminating messiness while maintaining carbonation effectiveness.
Solution Approach 2:
The disposable nature of the cartridges means they are discarded after a single controlled use, preventing accumulated mess from repeated cleaning cycles. All residue and byproducts are contained within the disposable cartridge that is thrown away, eliminating ongoing maintenance mess while ensuring consistent carbonation results.
3Reliability
If existing carbonation systems are used, then beverages can be carbonated, but the setups are not convenient for home use
Solution Approach 1:
The system separates the permanent base unit (containing the carbonation chamber and control electronics) from the disposable cartridges (containing chemicals and flavorings). This segmentation allows the complex carbonation function to be pre-engineered into the base unit, while the user only needs to perform the simple action of inserting a cartridge, greatly improving home convenience while maintaining reliable carbonation capability.
Solution Approach 2:
The cartridges are designed as ready-to-use, single-serving units that require no preparation, measurement, or cleaning. Users simply insert the pre-filled cartridge into the machine and receive a carbonated beverage, eliminating the complexity of home carbonation while ensuring consistent results through factory-prepared formulations.
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 the rapid production of highly carbonated beverages with controlled carbonation levels, using small volume cartridges to produce large volumes of carbonated beverages efficiently and conveniently, while minimizing waste and equipment complexity.
Implementation Method 1
a carbon dioxide source arranged to emit carbon dioxide gas for use in carbonating the precursor liquid... the carbon dioxide source may include a charged molecular sieve, such as a zeolite that is in solid form (e.g., pellets) and has adsorbed carbon dioxide, that releases carbon dioxide in the presence of water
Implementation Method 2
carbonating the precursor liquid using the carbon dioxide gas emitted by the first cartridge portion... a carbon dioxide gas supply arranged to conduct carbon dioxide gas emitted by the carbon dioxide source, under pressure greater than the ambient pressure, to beverage precursor liquid to carbonate the precursor liquid
Data Source
AI summary
Systems, methods and cartridges for carbonating a precursor liquid, such as water, to form a beverage. A carbon dioxide source can be provided in a cartridge which is used to generate carbon dioxide gas that is dissolved into the precursor liquid. A beverage medium, such as a powdered drink mix or liquid syrup, may be provided in the same, or a separate cartridge as the carbon dioxide source and mixed with the precursor liquid to form a beverage. The use of one or more cartridges for the carbon dioxide source and/or beverage medium may make for an easy to use and mess-free system for making carbonated beverages, e.g., in the consumer's home.
