Solution Overview
Problem
Existing flow-type carbonization apparatuses for beverages have low efficiency in dissolving carbon dioxide in water, leading to inefficient carbonation and potential germ formation due to stagnation in tanks.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If water is carbonized in a tank with stagnation, then carbon dioxide dissolution occurs, but germ formation increases and efficiency decreases
Solution Approach 1:
The patent implements continuous flow carbonization where water constantly moves through the system rather than stagnating in a tank. The carbonization process occurs continuously as water flows through the carbonation chamber, eliminating the harmful stagnation period while maintaining effective CO2 dissolution through extended residence time in the flow path
Solution Approach 2:
The patent extracts the water from the stagnation tank environment and processes it through a dedicated flow-type carbonization apparatus. By separating the carbonization function from the storage function, the system achieves efficient CO2 dissolution without the harmful effects of tank stagnation and germ formation
2Productivity
If conventional flow-type carbonization with Venturi nozzles is used, then carbon dioxide is introduced into water stream, but dissolution efficiency remains low
Solution Approach 1:
The patent segments the water flow into multiple streams using a multi-channel carbonation chamber with several injection points. This segmentation increases the surface area for gas-liquid contact and distributes the CO2 injection more evenly throughout the water flow, significantly improving dissolution efficiency compared to single-point Venturi injection
Solution Approach 2:
The patent transitions from conventional single-point gas injection to a multi-dimensional approach with multiple injection points arranged spatially within the carbonation chamber. This creates three-dimensional gas-liquid mixing patterns that enhance mass transfer and improve CO2 dissolution efficiency beyond conventional two-dimensional Venturi flow
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 apparatus achieves a carbon dioxide concentration of up to 5 g/l in water at 2°C and 4 g/l at 8°C, with an efficiency of approximately 60%, while minimizing stagnation and germ formation risks.
Implementation Method 1
a turbulence section located downstream of the gas inlet portion through which the pressurized liquid flows, when gas flows through the gas inlet portion
Implementation Method 2
the carbon dioxide bubbles are fragmented at the edge of the orifice of the inner pipe portion extending upstream into the outer pipe portion and solved by the liquid
Implementation Method 3
the recess around the inner pipe portion causes a turbulent flow supporting solving of the carbon dioxide in the liquid
