Solution Overview

Problem

Existing methods for preserving wine-containing liquids using dicarbonic acid diesters, particularly in wine barrels, suffer from inefficiencies such as underfilling or overfilling during treatment, high costs, and the need for complex online dosing pumps, leading to beverage loss and increased setup time.

Innovation Solution

A method and device that utilize a container, pump, and storage container with dicarbonic acid diesters, where the preservative is added through an injector, allowing for efficient mixing and preservation without online dosing pumps, reducing loss and complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If online dosing pumps are used to add dicarbonic acid diesters to wine-containing liquids, then the preservation effectiveness is improved, but the device complexity and operational costs increase significantly

Engineering Contradiction:
Improvepreservation effectivenessVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the dosing function from the complex online dosing pump system and implements it through a simple storage container with a dosing nozzle. The dosing nozzle is integrated directly into the container, eliminating the need for separate dosing equipment while maintaining preservation effectiveness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The storage container with dosing nozzle is designed to be self-sufficient, requiring no external control systems, power sources, or complex mechanisms. The container automatically doses the preservative through its integrated nozzle system, eliminating dependency on complex online dosing pump infrastructure.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If online dosing pumps are used for preservative addition, then dosing precision is improved, but the loss of wine-containing liquid increases due to underfilling or overfilling

Engineering Contradiction:
Improvedosing precisionVSAvoidbeverage loss
Core Design Contradiction:
Measurement precisionVSLoss of substance

Solution Approach 1:

The patent removes the complex feedback control and flow measurement systems from online dosing pumps and replaces them with a simple gravity-based dosing nozzle that delivers precise preservative amounts without requiring wine-containing liquid flow measurements or control systems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The dosing nozzle is designed as a simple, replaceable component that can be easily cleaned or replaced, eliminating the need for complex maintenance and calibration systems while maintaining dosing accuracy throughout its service life.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Extent of automation

If online dosing pumps are used, then the preservative dosing is automated, but the setup time and transport requirements increase

Engineering Contradiction:
Improvedosing automationVSAvoidsetup time
Core Design Contradiction:
Extent of automationVSLoss of time

Solution Approach 1:

The storage container with integrated dosing nozzle is designed as a self-contained unit that requires no installation, calibration, or connection to external control systems. It can be simply placed in the wine-containing liquid and begins dosing immediately, eliminating setup time entirely.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The storage container serves multiple functions simultaneously: storing the preservative, dosing it automatically, and floating to maintain proper dosing position. This multi-functionality eliminates the need for separate automation systems, transport equipment, and installation procedures.

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