Solution Overview

Problem

Existing beverage containers with pressure control systems for carbonated beverages often require external adjustment of pressure, which can lead to contamination and inefficiencies in dispensing, especially for foaming beverages like beer.

Innovation Solution

A container with an integrated pressure control unit and an aerosol valve that maintains desired dispensing pressure internally, using a coupling element to open and keep the valve open, ensuring a consistent dispensing pattern and preventing contamination by only allowing beverage flow, with a pressure control unit containing CO2 and adsorbing materials to maintain optimal pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external pressure adjustment is used for beverage containers, then pressure control is achieved, but contamination risk and operational complexity increase

Engineering Contradiction:
Improvedispensing pressure controlVSAvoidcontamination risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The pressure control device is merged with the beverage container by placing it inside the inner space of the container. The pressure control device includes a pressure gas holder that directly communicates with the beverage, eliminating the need for external pressure adjustment mechanisms and reducing contamination risk from external operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

A coupling element acts as an intermediary between the valve and the external environment. The coupling element includes a stem that pushes the valve open and remains coupled to the valve, providing a sealed connection that prevents contamination while maintaining pressure control.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If external pressure adjustment mechanisms are used, then pressure control is achieved, but device complexity and operational inefficiency increase

Engineering Contradiction:
Improvedispensing pressure controlVSAvoidexternal adjustment mechanisms
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The pressure control device is integrated inside the beverage container, combining multiple functions (pressure regulation, gas storage, and dispensing control) into a single internal system. This eliminates the need for separate external pressure adjustment mechanisms and tapping devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The pressure control device automatically maintains desired dispensing pressure through an automatically operating pressure controller that responds to pressure changes within the container. The system self-regulates without requiring external intervention or complex external adjustment mechanisms.

Inventive Principle:
Principle #25Self-service

3Productivity

If traditional aerosol valves are used for dispensing, then dispensing function is achieved, but repeated opening against spring pressure requires complex operating mechanisms

Engineering Contradiction:
Improvedispensing operationVSAvoidoperating mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The coupling element with its stem acts as a mediator that remains permanently coupled to the valve. The stem pushes the valve open and stays in place, eliminating the need for repeated complex operating mechanisms while maintaining the ability to control dispensing through the coupling element's design.

Inventive Principle:
Principle #24Intermediary (Mediator)
