Solution Overview

Problem

Existing valve units for beverage containers are structurally complex, laborious to assemble and disassemble, costly, and prone to malfunctions due to numerous components, including metal parts that can contaminate the beverage and require complex maintenance.

Innovation Solution

A simplified valve unit with integrated elastic means that allows the shutter to elastically deform between closed and open configurations, eliminating the need for a helicoidal spring and using a single mobile element, made from plastic materials to reduce complexity and contamination risks, and allowing for easy assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional valve units with helicoidal springs and multiple components are used, then reliable shutter control is achieved, but device complexity and manufacturing cost increase significantly

Engineering Contradiction:
Improveshutter control reliabilityVSAvoidvalve unit structural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the shutter and spring into a single integrated body made of elastomeric material. The shutter forms part of the body structure, and the elastic means are incorporated as integral features (such as embedded springs or elastomeric deformation zones) within the same component, eliminating the need for separate shutter and spring parts while maintaining reliable control functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The valve body is designed to perform multiple functions simultaneously: it serves as the structural housing, the shutter mechanism, and the spring assembly. The single body component integrates functions that traditionally required separate components, reducing overall device complexity while maintaining all necessary valve operations.

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

2Ease of operation

If multiple mobile components are used in the valve unit, then adjustable control is achieved, but ease of manufacture and assembly deteriorate

Engineering Contradiction:
Improvevalve control adjustabilityVSAvoidvalve unit assembly simplicity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The shutter and spring are combined into a single monolithic body that can be manufactured in one piece using injection molding or similar processes. This eliminates the need for separate assembly steps to combine multiple mobile components, greatly simplifying manufacturing while the integrated design still allows for controlled movement and adjustment.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If metal components are used in the valve unit, then mechanical strength is improved, but contamination risk and cleaning difficulty increase

Engineering Contradiction:
Improvevalve component strengthVSAvoidbeverage contamination risk
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The entire valve unit is constructed from a single material type - elastomeric polymer - eliminating metal components entirely. This homogeneous material composition ensures no metal contamination can occur while the elastomeric material provides sufficient mechanical strength through its inherent elasticity and durability.

Inventive Principle:
Principle #33Homogeneity

Solution Approach 2:

The patent uses advanced elastomeric materials that combine the properties of rubber (elasticity, flexibility) with the advantages of plastics (durability, contamination resistance). This composite approach replaces metal components while maintaining or improving mechanical performance and eliminating contamination risks.

Inventive Principle:
Principle #40Composite materials

4Adaptability or versatility

If numerous separate components are used, then functional versatility is achieved, but cleaning and sanitizing become laborious

Engineering Contradiction:
Improvevalve functionalityVSAvoidcleaning and sanitizing ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By consolidating multiple components (shutter, spring, housing) into a single integrated body, the patent creates a valve unit with smooth surfaces and no internal crevices where dirt can accumulate. The unified structure maintains all necessary valve functionalities while being completely cleanable and sanitizable as one piece, eliminating the laborious disassembly and cleaning of multiple separate parts.

Inventive Principle:
Principle #5Merging (Combining)
