Solution Overview

Problem

Conventional barrels experience issues with leakage, pressure fluctuations, oxidation, and volume limitations, leading to inconsistent fermentation processes and quality degradation in alcoholic beverages.

Innovation Solution

A hybrid system comprising two containers, a first container for raw materials and a second container for beverages/gases, maintains constant pressure and controlled atmosphere, using a second container to replace the bung for improved sealing and additional volume, allowing for scalable production without additives.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional barrels are used for storing and fermenting alcoholic beverages, then the traditional manufacturing and simplicity are maintained, but leakage, pressure fluctuations, and oxidation occur leading to quality degradation

Engineering Contradiction:
Improvesealing integrityVSAvoidbarrel construction
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention uses a composite construction combining wood staves for traditional aging characteristics with metal hoops and modern sealing materials (rubber gaskets, silicone seals) for structural integrity and leak prevention. This composite approach maintains the beneficial properties of wood while eliminating the leakage and oxidation problems of traditional barrels.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention employs flexible sealing components including rubber gaskets, silicone seals, and flexible membranes in the bung and stave joints. These flexible elements adapt to pressure changes during fermentation and aging while maintaining hermetic sealing, preventing both leakage and oxidation that plague conventional rigid barrel constructions.

Inventive Principle:
Principle #30Flexible shells and thin films

2Stress or pressure

If conventional barrels are used, then traditional design is maintained, but they are unable to maintain constant pressure during fermentation and aging processes

Engineering Contradiction:
Improvepressure controlVSAvoidfermentation consistency
Core Design Contradiction:
Stress or pressureVSProductivity

Solution Approach 1:

The invention actively controls and maintains constant pressure parameters during fermentation and aging by using adjustable hoop tensioning mechanisms and pressure-regulated sealing systems. This parameter control ensures consistent fermentation kinetics and prevents the quality variations caused by pressure fluctuations in traditional barrels.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system incorporates pressure monitoring and feedback mechanisms that detect pressure changes during fermentation and aging, automatically adjusting sealing forces and hoop tension to maintain constant pressure. This feedback control ensures consistent fermentation processes and prevents the inconsistent results typical of conventional barrels.

Inventive Principle:
Principle #23Feedback

3Volume of stationary object

If conventional barrels with fixed capacity are used, then traditional barrel sizes are maintained, but volume limitations restrict scalability for larger production batches

Engineering Contradiction:
Improvebarrel capacityVSAvoidproduction scalability
Core Design Contradiction:
Volume of stationary objectVSAdaptability or versatility

Solution Approach 1:

The invention segments the barrel into modular components including interchangeable stave sets, adjustable hoops, and detachable bung assemblies. This segmentation allows the barrel capacity to be easily modified by adding or removing stave sections, enabling scalable production from small to large batches without sacrificing the traditional barrel design benefits.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention employs dynamic, adjustable components including variable-length staves, adjustable hoop spacing, and expandable sealing systems that allow the barrel volume to be dynamically modified. This dynamic design enables the same barrel structure to adapt to different production volumes, from single-barrel to multi-barrel equivalent capacities.

Inventive Principle:
Principle #15Dynamics

4Reliability

If conventional barrels are used, then traditional construction methods are maintained, but poor sealing components lead to leakage and product loss

Engineering Contradiction:
Improveleakage preventionVSAvoidbarrel construction
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention introduces intermediary sealing components including rubber gaskets, silicone seals, and membrane barriers between the wood staves and外部环境. These intermediary elements act as mediators that prevent direct contact between the beverage and potential leakage paths, eliminating the leakage problems of conventional barrels while maintaining traditional wood construction methods.

Inventive Principle:
Principle #24Intermediary (Mediator)
