Bottom-Fill Fluid Transfer Assembly for Low-Foam Beverage Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for filling beverage containers often result in excessive foam formation with carbonated beverages, leading to waste and increased serving time, as they typically fill from the top, requiring multiple actions and physical contact, and occupy significant space.
Innovation Solution
A dispensing system that fills containers through their bottom, using a valve and magnetic coupling to create a fluid-tight seal, reducing foam by pushing it over the rim and incorporating features like a flushing system to prevent stale liquid accumulation and rapid drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If top filling method is used, then liquid can be transferred to serving container, but excessive foam is generated leading to waste and increased serving time
Solution Approach 1:
The patent inverts the conventional top-filling approach by implementing bottom-up filling. The serving container is filled from the bottom through a valve assembly, causing liquid to rise upward and foam to be pushed over the rim rather than generated during filling. This inversion of the filling direction fundamentally resolves the foam generation problem while maintaining efficient transfer.
Solution Approach 2:
The patent utilizes the phase behavior of carbonated beverages, where the liquid-foam transition occurs naturally during bottom-up filling. By controlling the filling process from bottom to top, the system allows the beverage to transition from liquid at the bottom to foam at the top, which then overflows cleanly without creating excessive waste.
2Productivity
If top filling method is used, then liquid transfer is achieved, but multiple manual actions and physical contact are required
Solution Approach 1:
The valve assembly is designed to automatically open when the serving container is placed on the dispensing system and automatically close when removed. The magnetic coupling mechanism self-activates upon proximity, eliminating the need for manual operation. This self-service capability reduces operational complexity while maintaining high filling efficiency.
Solution Approach 2:
The patent replaces manual mechanical operation with magnetic field-based actuation. The magnetic coupling device uses magnetic attraction to automatically open the valve when the container approaches and close it when removed, substituting complex manual mechanical controls with a simpler magnetic field-based system.
3Productivity
If conventional dispensing devices are used, then liquid transfer is possible, but large counter space is occupied
Solution Approach 1:
The patent merges the valve assembly, magnetic coupling device, and dispensing mechanism into a single integrated unit that attaches directly to the serving container. This consolidation eliminates the need for separate large-scale dispensing equipment, significantly reducing the counter space required while maintaining full liquid transfer capability.
Solution Approach 2:
The valve assembly is designed to nest within or attach to the serving container itself, with the magnetic coupling device integrating into the container structure. This nesting approach minimizes the footprint on the counter while preserving all necessary dispensing functions.

AI summary
A fluid dispensing assembly, including a valve, a housing, a user interface, and a fitting to couple to a fluid source. The valve may include a first sensor detecting proper placement of the fluid container based on a magnetic material positioned at the bottom of the fluid container, a plunger having a plunger shaft coupled thereto, the plunger selectively placing the valve in fluid communication with the fluid container, and a solenoid coupled to the plunger shaft and moving the plunger shaft to transition the plunger between an open position and a closed position. The user interface may be coupled to the valve to enable selection of at least a fluid container size and a dispensing mode.
