Solution Overview

Problem

Existing brewing systems face challenges in introducing additives, such as hops, into pressurized fermentation vessels while maintaining pressure levels and avoiding exposure to atmospheric conditions.

Innovation Solution

The use of an additive dispensing device with a vessel body having a chamber with a closed and open end, a pressure release means, and a controllable valve to selectively open and close a flow path between the chamber and the fermentation vessel, allowing for controlled introduction of additives.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If additives are introduced into the fermentation vessel by opening the vessel to atmosphere, then the additive can be easily added, but the pressure level in the vessel drops and sanitation may be compromised

Engineering Contradiction:

Improveease of additive introductionVSAvoidpressure level in fermentation vessel

Core Design Contradiction:

Ease of operationVSStress or pressure

Solution Approach 1:

The patent introduces an additive dispensing device as an intermediary component between the additive source and the fermentation vessel. This device includes a chamber that receives additives and a controllable valve that selectively opens to allow additive introduction. The pressure release means acts as another intermediary to manage pressure changes during the additive introduction process, allowing controlled pressure equalization without complete vessel opening to atmosphere.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the fermentation vessel is opened to atmosphere for additive introduction, then additives can be added, but exposure to atmospheric conditions compromises sanitation and stability

Engineering Contradiction:

Improveease of additive introductionVSAvoidexposure to atmospheric conditions

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The additive dispensing device serves as a protective intermediary that shields the fermentation vessel interior from direct atmospheric exposure. The chamber and valve mechanism allow additive transfer without requiring the vessel to be opened to atmosphere, thereby maintaining sanitation barriers and preventing contamination from atmospheric contaminants.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system maintains an inert or controlled atmosphere within the fermentation vessel by preventing direct contact with atmospheric air during additive introduction. The pressure release means carefully manages pressure equalization to allow additive flow while minimizing introduction of atmospheric contaminants, preserving the sterile environment necessary for beverage stability.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

3Stress or pressure

If a complex pressure control system is implemented to maintain pressure during additive introduction, then pressure stability is improved, but device complexity increases

Engineering Contradiction:

Improvepressure stability in fermentation vesselVSAvoidcomplexity of pressure control system

Core Design Contradiction:

Stress or pressureVSDevice complexity

Solution Approach 1:

The patent extracts the pressure control function from the main fermentation vessel system and places it in a separate, simpler additive dispensing device. The pressure release means is a dedicated component that handles pressure management independently, allowing the main fermentation vessel to maintain its pressure stability without being burdened by complex pressure control mechanisms.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The pressure release means operates autonomously to manage pressure during additive introduction. It automatically equalizes pressure differences between the chamber and fermentation vessel without requiring complex external control systems, allowing the system to self-regulate pressure conditions while maintaining stability.

Inventive Principle:

Principle #25Self-service
