Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-pressure carbonation systems for carbonated soft drink equipment are costly due to the need for heavy, expensive components and high-pressure pumps, and require complex pressure regulation for CO2 gas, leading to increased operational costs and reliability issues.
Innovation Solution
A low-pressure carbonation system that operates between 50-120 PSI, using a CO2 cylinder, a low-pressure pump, and a controller to manage water levels and CO2 pressure, reducing the need for heavy components and simplifying pressure regulation by maintaining CO2 at 55 PSI for both carbonation and syrup dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high-pressure carbonation is used to meet gas volume specifications, then soda strength is improved, but equipment cost and component weight increase
Solution Approach 1:
The patent changes the pressure parameter from high-pressure to low-pressure operation (50-60 PSI for carbonation, 55 PSI for syrup dispensing). This parameter change allows the system to achieve required gas volume specifications while using lighter components such as plastic tubing and plastic quick connectors instead of heavy metal components designed for high-pressure systems.
2Quantity of substance
If high-pressure carbonation is used to meet gas volume specifications, then soda strength is improved, but equipment cost increases
Solution Approach 1:
The patent changes the pressure parameter from high-pressure to low-pressure operation, enabling the use of cheaper materials such as plastic tubing and plastic quick connectors instead of expensive high-pressure rated metal components. This significantly reduces equipment manufacturing cost while maintaining functional performance.
Solution Approach 2:
The patent uses a single CO2 regulator that serves dual functions: regulating CO2 pressure for carbonation (50-60 PSI) and for syrup dispensing (55 PSI). This multi-functionality eliminates the need for separate regulators, reducing component count and overall equipment cost.
3Manufacturing precision
If complex pressure regulation is used for CO2 gas, then carbonation control is improved, but device complexity increases
Solution Approach 1:
The patent employs a single CO2 regulator that controls pressure for both carbonation (50-60 PSI) and syrup dispensing (55 PSI). This multi-functional approach simplifies the pressure regulation system by eliminating multiple regulators and associated control mechanisms, reducing device complexity while maintaining precise carbonation control.
Solution Approach 2:
The patent merges the pressure regulation functions for carbonation and syrup dispensing into a single regulator unit. This consolidation reduces the number of components, simplifies the control system, and lowers overall device complexity while achieving the required precision for both functions.
4Speed
If high-pressure pumps are used, then water delivery is improved, but reliability decreases
Solution Approach 1:
The patent changes the operating pressure parameter from high-pressure to low-pressure (60-120 PSI for the low-pressure pump). This reduction in pressure decreases the mechanical stress on pump components and tubing, reducing wear and failure rates, thereby improving system reliability while maintaining adequate water delivery speed for carbonation.

AI summary
A carbonated drink dispensing system includes a carbonation tank, a CO2 cylinder configured to deliver CO2 to the carbonation tank at a pressure of between 50 psi and 60 psi, a low-pressure pump configured to pump water into the carbonation tank, and a level sensor configured to determine when the water in the carbonation tank has reached a pre-determined level. The low-pressure pump is configured to stop pumping water when the level sensor determines that the water in the carbonation tank has reached the pre-determined level. The low-pressure pump starts pumping water again after a time delay.
