Solution Overview

Problem

Batch carbonation processes in beverage dispensers result in stale carbonated water due to storage and lack of customizable carbonation levels, as they carbonate water in batches rather than continuously on demand.

Innovation Solution

An in-line carbonation system utilizing a hollow fiber membrane carbonator integrated with a chilling reservoir, allowing for continuous carbonation of water on demand, with customizable carbonation levels achieved by varying CO2 pressure, and eliminating the need for stored carbonated water.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If batch carbonation process is used to carbonate water in a mixing tank, then carbonated water can be produced, but the carbonated water becomes stale due to storage and fixed carbonation levels

Engineering Contradiction:
Improvecarbonation qualityVSAvoidcustomizable carbonation levels
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system transitions from batch carbonation to continuous in-line carbonation where water is carbonated continuously as it flows through the hollow fiber membrane carbonator integrated with the chilling reservoir, eliminating storage and maintaining freshness

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system enables dynamic adjustment of carbonation levels by varying CO2 pressure in real-time during the carbonation process, allowing customizable carbonation levels rather than fixed batch carbonation

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If batch carbonation process is used with a mixing tank, then carbonated water can be stored, but storage causes staleness and quality degradation

Engineering Contradiction:
Improvecarbonated water storageVSAvoidcarbonation quality
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The system carbonates water continuously on-demand as it flows through the integrated carbonator-chilling reservoir, eliminating the need for storage and ensuring fresh carbonated water is produced only when needed

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system extracts the carbonation function from a separate batch mixing tank and integrates it directly into the water flow path within the chilling reservoir, eliminating the storage intermediate step that causes staleness

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If hollow fiber membrane carbonator is integrated with chilling reservoir, then continuous carbonation on demand is achieved, but device complexity increases

Engineering Contradiction:
Improvecontinuous carbonation on demandVSAvoidintegrated carbonator-chilling reservoir
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system merges the carbonation function and chilling function into a single integrated unit where the hollow fiber membrane carbonator is positioned within the chilling reservoir, combining two separate processes into one compact device

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated chilling reservoir serves multiple functions: it chills the water, houses the carbonation chamber, and provides the structural framework for the entire system, reducing the need for separate components

Inventive Principle:
Principle #6Universality (Multi-functionality)
