Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispensing devices for carbonated beverages fail to maintain the beverage under a regulated pressure effectively, leading to loss of carbonation and affecting taste and appearance, while also being costly and complex in construction.
Innovation Solution
A compact, cost-effective regulated fluid dispensing device with a main housing containing a regulator, pressure relief mechanism, and tap handle group, using a molded thermoplastic construction and a CO2 gas cartridge to maintain beverage pressure, allowing for controlled dispensing over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a regulated pressure system is implemented to maintain beverage carbonation, then the beverage quality (taste and appearance) is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple functions (pressure regulation, gas storage, beverage dispensing, and pressure relief) into a single integrated device. The regulator, CO2 cartridge, delivery tube, and relief mechanism are merged into one compact unit that attaches directly to the beverage container, eliminating the need for separate components and reducing overall system complexity.
Solution Approach 2:
The device performs multiple functions simultaneously: it regulates pressure to maintain carbonation, stores supplemental CO2 gas, dispenses the beverage through a tap mechanism, and provides pressure relief through a relief valve. This multi-functionality reduces the need for multiple separate devices while maintaining reliable carbonation control.
2Reliability
If a regulated pressure system with multiple components is used to maintain beverage pressure, then the carbonation control is improved, but the manufacturing cost increases
Solution Approach 1:
The patent combines multiple functions (pressure regulation, gas storage, beverage dispensing, and pressure relief) into a single integrated device. The regulator, CO2 cartridge, delivery tube, and relief mechanism are merged into one compact unit that attaches directly to the beverage container, eliminating the need for separate components and reducing overall system complexity.
Solution Approach 2:
The device uses a disposable CO2 cartridge that is replaced when depleted, eliminating the need for complex gas refilling mechanisms. The regulator and housing are designed as durable reusable components, while the cartridge serves as a low-cost consumable item that simplifies manufacturing and maintenance.
3Reliability
If gas is continuously supplied to maintain pressure, then the beverage remains carbonated, but the risk of over-pressurization and container damage increases
Solution Approach 1:
The regulator monitors the pressure within the beverage container and automatically adjusts the gas flow from the CO2 cartridge to maintain a preset pressure level. When the desired pressure is reached, the regulator closes the gas supply, preventing over-pressurization while maintaining optimal carbonation levels.
Solution Approach 2:
The pressure relief valve is pre-configured to automatically open and vent excess gas if the pressure exceeds a predetermined safety threshold. This protective mechanism is built into the system beforehand to prevent container damage from over-pressurization, providing a safety cushion against pressure anomalies.
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 device effectively maintains beverage carbonation, prevents over-pressurization, and simplifies manufacturing and assembly, providing a reliable and efficient means to dispense beverages while reducing manufacturing costs.
Implementation Method 1
a regulator that controls the flow of pressurized gas into the container to maintain a selected gas pressure
Implementation Method 2
The pressure relief mechanism includes a spring that allows gas to escape from the container when the pressure exceeds a predetermined level
Implementation Method 3
A removable gas cartridge is used to pressurize the contents of the container

AI summary
A device and method are provided for dispensing a beverage from a pressurized container. The dispensing device includes an integral source of compressed gas for maintaining the beverage within the container at a desired pressurized state. The dispensing device also includes a regulator for controlling the flow of gas from the compressed gas source to the interior of the container, as well as a pressure relief mechanism that accounts for potential over pressurization of the container. The beverage is selectively dispensed by actuation of a tap handle. Delivery is achieved through the device by a resilient delivery tube, and the delivery tube is either pinched closed or allowed to decompress by the actuation of the tap handle. In another embodiment, a check valve is used to control flow of the beverage in which the tap handle activates a transfer rod to seat and unseat a check element.
