Solution Overview

Problem

Existing in-home beverage dispensing systems are cumbersome, require frequent replenishment of supplies, and lack the ability to easily switch between multiple drinks without risk of cross-contamination.

Innovation Solution

A fluid dispensing system with two containers, each connected to a faucet via separate hoses, controlled by switches that allow for sequential dispensing of different fluids, including filtered water and carbonated beverages, while preventing cross-contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single container and hose system is used for dispensing multiple beverages, then device complexity is reduced, but cross-contamination between different beverages occurs

Engineering Contradiction:

Improvesystem structureVSAvoidcross-contamination

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The system divides the beverage dispensing infrastructure into separate, dedicated components for each beverage type. Each beverage has its own container, hose, and dispensing pathway, physically segmenting the system to prevent cross-contamination while maintaining operational simplicity through modular design

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple beverage containers are stored in the refrigerator, then beverage variety is improved, but storage space is consumed and containers occupy substantial space

Engineering Contradiction:

Improvebeverage varietyVSAvoidstorage space

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The beverage containers are extracted from the refrigerator storage space and placed in wall-mounted positions. This removes the need for large refrigerator存储空间 while maintaining access to multiple beverage types, effectively separating storage function from dispensing function

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The wall-mounted dispensing unit serves multiple functions: it stores multiple beverage types, provides automated dispensing control, and eliminates the need for separate refrigerator storage space. The system handles both storage and dispensing operations within a compact wall-mounted structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Volume of stationary object

If manual beverage preparation is performed, then storage space requirements are reduced, but time consumption and labor burden increase significantly

Engineering Contradiction:

Improvestorage spaceVSAvoidpreparation time

Core Design Contradiction:

Volume of stationary objectVSLoss of time

Solution Approach 1:

The system enables self-service beverage dispensing through automated control mechanisms. Users can select and dispense beverages independently without requiring manual preparation, mixing, or handling of ingredients, significantly reducing the time and effort previously required for beverage preparation

Inventive Principle:

Principle #25Self-service

4Volume of stationary object

If a concentrated drink supply system is used, then storage space is reduced, but the system requires frequent monitoring and replenishment of syrup and CO2 levels

Engineering Contradiction:

Improvestorage spaceVSAvoidmaintenance effort

Core Design Contradiction:

Volume of stationary objectVSEase of operation

Solution Approach 1:

The system incorporates level sensing and monitoring mechanisms that provide feedback when beverage supplies are low. This automated monitoring reduces the need for manual checking and tracking of syrup and CO2 levels, making the system easier to operate while maintaining compact storage

Inventive Principle:

Principle #23Feedback

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Implementation Method 1

a pump configured to supply air to the second hose when the second switch is turned off

Methodology Applied

Scientific EffectAir pressure: Pressure Increase

Implementation Method 2

a gas is released from the second fluid in the second container... the second container supplies the second fluid to the second hose based on a pressure caused by the released gas

Methodology Applied

Scientific EffectGas pressure: Pressure Increase

AI summary

A dispenser system includes a first container configured to contain a first fluid, a second container configured to contain a second fluid, a faucet coupled with the first container and the second container via first and second hoses, respectively, and including first and second switches installed on the faucet, and a controller configured to control dispensing of the first and second fluids through the faucet. When the first switch is turned on while the second switch is turned off, the controller dispenses the first fluid to the faucet through the first hose. When the first switch is turned off while the second switch is turned on, the controller dispenses the second fluid to the faucet through the second hose. The dispenser system is configured and dimensioned to prevent cross contamination between the first and second hoses.
