CO2 Cartridge Pressure Indicator for Low-Gas Warnings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home-use carbonation devices lack the ability to indicate the current content of CO2 cartridges, leading to user frustration when the cartridge runs out unexpectedly, as they do not provide warnings for low CO2 levels.
Innovation Solution
A device with a pressure indication system that monitors the CO2 cartridge pressure, switching states to indicate high or low CO2 levels, allowing users to track the remaining content and receive timely notifications for refills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a gas cartridge is used in a home carbonation device, then the device can carbonate water, but the user cannot know the current content of the gas cartridge
Solution Approach 1:
A pressure indication device is introduced as an intermediary component between the gas cartridge and the user. This device visually indicates the gas cartridge content level through pressure-based state changes, allowing users to monitor gas levels without complex electronic displays or additional sensors.
Solution Approach 2:
The pressure indication device utilizes color changes or visual state changes to indicate different gas cartridge content levels. When the gas pressure drops below a threshold, the indication device changes its visual state (e.g., color, position, or illumination) to warn the user that the cartridge is running low.
2Reliability
If the gas cartridge is depleted unexpectedly, then the user experiences frustration, but providing continuous monitoring increases device complexity
Solution Approach 1:
The pressure indication device provides advance warning before the gas cartridge is completely depleted. By indicating low gas levels in advance, the system allows users to replace the cartridge proactively, preventing the frustration of unexpected depletion and ensuring continuous operation.
Solution Approach 2:
The system provides visual feedback to the user about the gas cartridge status through the pressure indication device. This feedback loop allows users to monitor gas levels and take appropriate action, improving reliability of the carbonation system by preventing unexpected failures.

AI summary
The invention relates to a device (5) for mixing a beverage with a gas, comprising a gas providing unit (101), a pressure indication device (50) fluidically connectable with a gas cartridge (100) of the gas providing unit (101), such that the first pressure prevails in the pressure indication device (50), and a gas line (7), such that the gas is feedable in a liquid container (9) via the gas line (7), such that the beverage is mixed with the gas when the beverage resides in the liquid container (9). The pressure indication device (50) is configured to be at least in a first state indicating a high quantity of gas in the gas cartridge (100) and in a second state indicating a low quantity of gas in the gas cartridge (100). The state of the pressure indication device (50) indicates whether the first pressure is above or below a predefined threshold.
