Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional beer manufacturing processes are used with large fermentation tanks, then production scale is increased, but equipment investment and manpower requirements increase significantly

Engineering Contradiction:
Improveproduction scaleVSAvoidequipment investment
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention divides the fermentation process into two independent stages: wort preparation in a small keg (0.5-2 liters) and fermentation in a separate fermenter. This segmentation allows each component to be miniaturized and simplified, reducing overall equipment investment while maintaining production capability. The wort can be prepared in advance and stored, then fermented separately when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention allows wort to be prepared and stored in advance in a keg before fermentation. This preliminary action separates the time-consuming wort preparation from the fermentation process, enabling batch production where multiple worts can be prepared ahead of time and then fermented in sequence, increasing productivity without requiring proportionally larger equipment.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If wort is transferred from keg to fermenter for fermentation, then fermentation can proceed, but contamination risk increases due to contact with outside environment

Engineering Contradiction:
Improvefermentation efficiencyVSAvoidcontamination risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The invention introduces a sealed transfer mechanism with a valve system that acts as an intermediary between the keg and fermenter. The wort is transferred through a closed管路 (pipeline) with valves that can be opened and closed to control flow, preventing exposure to the external environment during transfer. This intermediary system maintains sterility while enabling the necessary process steps.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention creates a sealed, controlled environment for both the keg and fermenter that isolates the wort and yeast from the external atmosphere. The fermentation occurs in a closed system where air and contaminants are excluded, effectively creating an inert environment that prevents contamination while allowing aerobic or anaerobic fermentation as required.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

3Reliability

If sterilization is performed on all contact surfaces, then contamination is prevented, but time and labor manpower increase

Engineering Contradiction:
Improvesterility maintenanceVSAvoidsterilization time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The invention implements preliminary sterilization of all contact surfaces (keg, fermenter, pipelines, valves) before the fermentation process begins. By completing sterilization in advance and maintaining closed systems throughout, the need for repeated sterilization during the process is eliminated, saving time and labor while maintaining sterility.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention maintains continuous sterility through sealed systems and closed操作流程 (operating procedures). Once sterilized, the system remains closed throughout wort preparation, storage, and fermentation, preventing recontamination without requiring additional sterilization steps. This continuous protective action maintains reliability without repeated time-consuming interventions.

Inventive Principle:
Principle #20Continuity of useful action

4Reliability

If professional personnel manage the whole manufacturing process, then beer quality is controlled, but manpower requirements and operational complexity increase

Engineering Contradiction:
Improvebeer quality controlVSAvoidoperational simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention divides the manufacturing process into distinct, standardized stages (wort preparation in keg, fermentation in separable fermenter) that can be executed independently. This segmentation creates clear procedural steps that are easier to follow and control, reducing the need for highly skilled personnel while maintaining quality through systematic process control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces a sealed transfer mechanism with valve control as an intermediary system that automates and simplifies the connection between keg and fermenter. This intermediary system with standardized interfaces and controlled operations reduces the skill level required for manual operations while maintaining process reliability and beer quality through consistent, repeatable procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)
