Solution Overview

Problem

Existing liquid containers for alcohol production and storage, such as those made of wood, stainless steel, plastic, and concrete, face issues like limited reuse, chemical reactivity, and inadequate gas exchange, leading to suboptimal wine production and preservation.

Innovation Solution

A liquid container with an inner wall surface made of natural stone, treated to enhance roughness and specific surface area, allowing for intensive gas exchange and complete chemical reactions with a limited supply of additives, and featuring a design that can be reused indefinitely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional materials (wood, stainless steel, plastic, concrete) are used for liquid containers, then the container structure is stable and easy to manufacture, but the container shows limited reuse capability and chemical reactivity issues

Engineering Contradiction:
Improvereuse capabilityVSAvoidchemical reactivity
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The natural stone material possesses inherent porous structure that enables gas exchange between the liquid and external environment. This porosity allows beneficial aeration and chemical reactions while maintaining material stability and resistance to chemical degradation from alcoholic beverages.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The container utilizes natural stone as a composite material that combines multiple desirable properties: chemical inertness toward alcohol, structural stability, and controlled porosity for gas exchange. This natural composite structure eliminates the need for additional chemical treatments or coatings.

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If the inner wall surface is made smooth for easy cleaning, then the container is easier to maintain, but gas exchange and chemical reactions are insufficient

Engineering Contradiction:
Improvegas exchange intensityVSAvoidcleaning ease
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The natural stone surface maintains its inherent roughness and porous structure in the regions critical for gas exchange and chemical reaction. This localized preservation of surface quality enables intensive interaction between the liquid and container wall without requiring the entire surface to be rough.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The porous structure of natural stone provides numerous micro-channels and surface areas that facilitate gas exchange and chemical reactions. The porous nature inherently increases surface area available for interaction while the material's durability ensures long-term functionality.

Inventive Principle:
Principle #31Porous materials

3Productivity

If natural stone is used for the container, then gas exchange and chemical reactions are enhanced, but the manufacturing complexity increases

Engineering Contradiction:
Improvewine production qualityVSAvoidmanufacturing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention extracts and utilizes the beneficial natural properties of stone material directly, without adding complex processing steps or artificial modifications. The natural porosity and chemical stability of the stone are leveraged as-is, simplifying the overall manufacturing approach despite using natural stone.

Inventive Principle:
Principle #2Taking out (Extraction)

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 natural stone container promotes the development of fruity wines by enhancing gas exchange and chemical reactions, while being resistant to chemical substances, thus improving wine production and storage efficiency.

Implementation Method 1

a first roughness has been produced by cleaving or drilling or sawing the natural stone or by treatment with a sandblast and has then been subjected to a surface treatment that has caused the roughness of the treated inner wall surface to have been increased in relation to the first roughness initially produced. In particular, in the production (fermentation) of wine, it has been found that a natural stone surface has a natural roughness with a degree of roughness that allows intensive gas exchange with the liquid to be produced

Methodology Applied
Scientific EffectGas exchange: Diffusion

Implementation Method 2

a natural stone surface has a natural roughness with a degree of roughness that allows intensive gas exchange with the liquid to be produced and complete chemical conversion with a limited supply of additives that initiate or promote the reaction

Methodology Applied
Scientific EffectChemical reactions: Chemical Bonding

Implementation Method 3

At the same time, a natural stone surface is resistant to a large number of chemical substances, including fruit acids, so that a liquid container designed according to the invention can be reused essentially indefinitely
