Solution Overview

Problem

Conventional methods for serving beverages, especially carbonated drinks, often result in excessive foam due to turbulence during filling, requiring manual intervention and increased serving time, and existing bottom-filling container systems rely on external magnetic rings for closure, complicating manufacturing and hygiene compliance.

Innovation Solution

A container design with a bottom incorporating ferromagnetic particles directly into non-magnetic materials like plastic or glass, eliminating the need for external magnetic rings and ensuring food hygiene standards, featuring a shutter with a magnetized face for closure and recognition means like circular beads for volume detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a magnetic ring is attached to the base of the container to hold the stopper in the closed position, then the stopper can be reliably held against the base by magnetic attraction, but the manufacturing process is complicated and food hygiene standards may not be met

Engineering Contradiction:
Improvestopper closure reliabilityVSAvoidmanufacturing simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges the magnetic closure system into a single integrated component by incorporating ferromagnetic particles directly into the base material during molding. This eliminates the need for a separate magnetic ring attachment step, simplifying manufacturing while maintaining the magnetic attraction function that holds the stopper in place.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base is manufactured as a composite material combining a non-magnetic base material (such as plastic or glass) with ferromagnetic particles dispersed throughout. This composite structure provides both the necessary magnetic properties for stopper retention and the hygiene benefits of a seamless, moldable single-piece construction.

Inventive Principle:
Principle #40Composite materials

2Productivity

If carbonated beverages are filled from the top using traditional dispensers, then the beverage can be served, but turbulence during filling generates excessive foam requiring manual intervention

Engineering Contradiction:
Improvebeverage service speedVSAvoidexcessive foam
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent inverts the traditional filling approach by filling the container from the bottom upward rather than from the top downward. The beverage is injected through a nozzle that enters through the base opening, allowing the liquid to rise gently to the top without creating turbulence or excessive foam, thereby eliminating the need for manual foam removal.

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

3Loss of time

If a bottom-filling system with magnetic closure is implemented, then beverage service time is reduced and multitasking is enabled, but the device complexity increases with multiple components

Engineering Contradiction:
Improvebeverage service timeVSAvoidcontainer system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into the base component itself: the base provides structural support, contains the ferromagnetic particles for closure, and features an opening for bottom filling. This integration reduces the number of separate parts and assembly steps while enabling rapid beverage service through the bottom-filling mechanism.

Inventive Principle:
Principle #5Merging (Combining)
