Solution Overview

Problem

Conventional methods for filling beverage containers often result in excessive foam formation, particularly with carbonated beverages, leading to liquid wastage and increased serving time due to the need for top filling, which requires multiple actions and physical contact, and occupy significant space.

Innovation Solution

A dispensing system that allows filling through the bottom of the container using a valve and connection devices with magnetic components to create a fluid-tight seal, reducing foam formation by pushing it over the rim and enabling automatic or semi-automatic operation with a user interface for controlling fluid flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If top filling method is used, then liquid can be transferred to serving container, but excessive foam is generated and liquid is wasted

Engineering Contradiction:
Improveliquid transfer efficiencyVSAvoidliquid wastage due to foam
Core Design Contradiction:
Quantity of substanceVSLoss of substance

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, allowing liquid to rise through the container and push foam upward and outward over the rim, thereby reducing foam loss and improving liquid transfer efficiency.

Inventive Principle:
Principle #13The other way round (Inversion)

2Quantity of substance

If top filling method is used, then liquid can be transferred, but multiple manual actions are required increasing serving time

Engineering Contradiction:
Improveliquid transferVSAvoidserving time due to multiple actions
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The system enables self-service operation where the server simply places the serving container on the dispenser. The valve assembly automatically detects the container presence and initiates the filling process without requiring the server to manually start or control the flow, reducing serving time and manual intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical control with an automated valve assembly that uses magnetic components and sensors to detect container presence and control liquid flow automatically, eliminating the need for manual operation steps.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If top filling method is used, then liquid can be transferred, but significant counter space is required

Engineering Contradiction:
Improveliquid transfer capabilityVSAvoidcounter space occupation
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The valve assembly is designed to nest within or attach to the base of the serving container, rather than requiring a separate large dispensing apparatus on the counter. This compact integration reduces the footprint and space requirements on the counter while maintaining liquid transfer functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Quantity of substance

If top filling method is used, then liquid can be transferred, but physical contact and coordination are required during operation

Engineering Contradiction:
Improveliquid transferVSAvoidoperation simplicity
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The automated valve assembly with magnetic detection and flow control eliminates the need for the server to physically manipulate or coordinate during the filling process. The system automatically detects when the container is in place and controls the liquid flow, making operation simple and foolproof.

Inventive Principle:
Principle #25Self-service
