Solution Overview

Problem

Current wine-making methods do not effectively manage fermentation gases to efficiently mix and break the cap in fermentation tanks, leading to suboptimal wine production.

Innovation Solution

A method and apparatus that involves storing crushed material in a first tank to form a cap, capturing and pumping fermentation gases into a second tank to create a pressure differential, allowing spontaneous gas transfer into the liquid mass to interact with the cap, and mechanically pumping gases into the second tank for controlled pressure management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If gases are used to push the cap upwards and compact it, then the cap forms a solid layer, but the gases are not effectively utilized to mix and break the cap

Engineering Contradiction:
Improvewine production efficiencyVSAvoidcap mixing and breaking effectiveness
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

A second tank is introduced as an intermediary device between the fermentation tank and the cap. This tank captures fermentation gases, pressurizes them, and reintroduces them under the cap to achieve effective mixing and breaking, resolving the inefficiency of direct gas use

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Fermentation gases are extracted from the fermentation tank and transferred to a separate second tank for processing. This separation allows the gases to be pressurized and controlled independently before being reintroduced to break the cap, improving overall process efficiency

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If a second tank is added to capture and pressurize gases, then gas utilization improves, but the device complexity increases

Engineering Contradiction:
Improvegas utilization efficiencyVSAvoidnumber of tanks and connections
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The second tank serves multiple functions: capturing fermentation gases, pressurizing them through compression, storing the pressurized gases, and reintroducing them under the cap. This multi-functionality justifies the added complexity by consolidating multiple operations into a single device

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

Solution Approach 2:

The system merges gas capture, compression, storage, and reintroduction functions into an integrated two-tank system with coordinated valve control. This combination improves gas utilization efficiency while managing complexity through functional integration

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If gases are spontaneously transferred into the liquid mass, then the process is simplified, but pressure control precision is reduced

Engineering Contradiction:
Improvegas transfer automationVSAvoidpressure control accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

Pressure sensors are installed in both tanks to monitor gas pressure in real-time. The control unit receives feedback from these sensors and automatically activates or deactivates the pump and valves to maintain precise pressure control during gas transfer and cap breaking operations

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Manual pressure control is replaced with an automated electronic control system that uses pressure sensors and a control unit to manage gas transfer. This substitution maintains ease of operation while significantly improving pressure control precision

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
