Solution Overview

Problem

Existing beverage preparation systems using flexible packs face issues such as pressure-induced bubble formation, uncontrollable rupture, inefficient dissolution, and inability to optimize product dispense based on ingredients, leading to residual product and high flow times, as well as limitations in producing foam.

Innovation Solution

A pack design with a primary and secondary fluid inlet arranged to create optimal turbulence, allowing independent management of aqueous and gaseous fluid injection, which enhances dissolution and foam production by injecting air and water at high velocity from the bottom, reducing flow time and ensuring complete product extraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pressure is increased to open the closing means, then the beverage can evacuate through the outlet, but bubbles form at the surface and the opening becomes uncontrollable

Engineering Contradiction:
Improvebeverage evacuationVSAvoidbubble formation and uncontrollable rupture
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent divides the fluid inlet function into two separate inlets: a primary fluid inlet for water injection and a secondary fluid inlet for air injection. This segmentation allows independent control of each fluid stream, enabling the air inlet to create turbulence and prevent bubble formation while the water inlet provides controlled pressure for beverage evacuation without uncontrollable rupture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces air as an intermediary substance through the secondary fluid inlet. This air stream acts as a mediator that creates turbulence and mixing in the beverage, preventing bubble formation at the surface while facilitating smooth evacuation through the outlet, thus resolving the harmful effects of direct high-pressure water injection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If water is injected from top to bottom, then the sachet can be simply designed, but dissolution is inefficient and flow time is high

Engineering Contradiction:
Improvesachet designVSAvoiddissolution efficiency and flow time
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent inverts the conventional top-to-bottom water injection approach by introducing air from the bottom through the secondary fluid inlet. This inversion creates upward turbulence and mixing that dramatically improves dissolution efficiency and reduces flow time, while the simple dual-inlet design maintains ease of manufacture.

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

Solution Approach 2:

The patent uses the air injection through the secondary fluid inlet to create mechanical turbulence and vibration within the beverage. This turbulence enhances the mixing and dissolution of the beverage ingredient, significantly improving dissolution efficiency and reducing flow time without complicating the sachet design.

Inventive Principle:
Principle #18Mechanical vibration

3Device complexity

If a single fluid inlet is used, then the device is simple, but it cannot independently manage aqueous and gaseous fluid injection for optimized product dispense

Engineering Contradiction:
Improveinlet configurationVSAvoidfluid management flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent segments the fluid inlet system into two distinct inlets: a primary fluid inlet for aqueous fluid and a secondary fluid inlet for gaseous fluid. This segmentation enables independent management of each fluid type, providing the flexibility to optimize product dispense for different ingredients while maintaining a relatively simple dual-inlet device structure.

Inventive Principle:
Principle #1Segmentation
