Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sulphites are used for microbial control and disinfection, then microbial load is eliminated, but quality alterations and allergic effects occur

Engineering Contradiction:
Improvemicrobial controlVSAvoidquality alterations and allergic effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies ozone, a strong oxidant, to replace sulphites for disinfection and microbial control in wine making. Ozone effectively eliminates microbial loads while avoiding the quality alterations and allergic effects associated with sulphite use. The process involves treating grapes, must, and wine with ozone at controlled concentrations to achieve sanitization without the harmful side effects of traditional sulphite-based methods.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

2Reliability

If sulphites are added in excess to ensure sanitizing effect, then microbial control is improved, but total sulphite quantity increases

Engineering Contradiction:
Improvesanitizing effectVSAvoidtotal sulphite quantity
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent replaces excessive sulphite addition with ozone treatment, achieving effective sanitization at lower overall substance quantities. Ozone's potent oxidizing capability allows for microbial control without the need to add large amounts of sulphites, thereby reducing the total sulphite quantity in the final wine product while maintaining sanitizing effectiveness.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

3Reliability

If traditional disinfection methods are used, then microbial load is reduced, but residual contaminants remain

Engineering Contradiction:
Improvemicrobial load eliminationVSAvoidresidual contaminants
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent uses ozone, a strong oxidant that decomposes into oxygen, to eliminate microbial loads without leaving harmful residual contaminants. Unlike sulphites that leave residual sulphite ions, ozone breaks down completely, providing effective disinfection while avoiding contamination from residual substances in the final wine product.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

4Reliability

If sulphites are used for oxidation control, then microbial development is controlled, but hydrogen sulphide formation occurs

Engineering Contradiction:
Improveoxidation controlVSAvoidhydrogen sulphide formation
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces sulphite-based oxidation control with ozone treatment. Ozone provides effective oxidation control to manage microbial development while avoiding the formation of hydrogen sulphide and other unpleasant odors associated with sulphite use. The strong oxidizing power of ozone controls microbial growth without generating harmful byproducts.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

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

The ozone treatment effectively eliminates microbial loads, increases the concentration of beneficial compounds like polyphenols and anthocyanins in wine, and reduces sulphite levels, producing a healthier and higher-quality wine with lower environmental impact.

Implementation Method 1

disinfection is an extremely important procedure. For this purpose chlorine or other chemical compounds are generally used... sulphur dioxide, which in addition to eliminating the overall microbial load present in the product

Methodology Applied
Scientific EffectOxidation: Oxidation

Implementation Method 2

the high instability of the molecule used in the form of ozone (O3), which rapidly degrades to reform oxygen (O2) without leaving residues which are harmful or which can negatively alter the wine quality

Methodology Applied
Scientific EffectDecomposition: Decomposition (biological)

Implementation Method 3

experimental results obtained by treating harvested products, in terms of elicitation effect due to induced superoxidative stress, by the stimulus and accumulation of added value substances of salutistic type for man (mainly flavanol, flavonols and stilbenes)

Methodology Applied
Scientific EffectOxidative stress: Oxidation
