Integrated Pressure Vessel Valves for Compact Lateral Outflow

Solution Overview

Problem

Existing pressure vessels with protruding valves for lateral outflow require additional material and assembly complexity, leading to increased height and cost, while integrated valves often compromise structural integrity and material efficiency.

Innovation Solution

A pressure vessel design with integrated non-return valves having a single passage opening and two lateral outflow openings, utilizing a fastening structure and connection geometry to ensure media-tight coupling, reducing material thickness and assembly complexity, and allowing for uniform medium distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a valve protrudes from the container body to enable lateral outflow, then lateral outflow is achieved, but the overall height increases and material cost increases

Engineering Contradiction:

Improvelateral outflow capabilityVSAvoidoverall height

Core Design Contradiction:

Ease of operationVSLength of stationary object

Solution Approach 1:

The valve is integrated into the end region of the container body, merging the valve structure with the container wall. The valve body is arranged substantially in the end region with only a collar-shaped upper section protruding, eliminating the need for a separate protruding valve assembly and reducing overall height while maintaining lateral outflow capability through the two outflow openings in the container wall.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The outflow openings are arranged laterally in the container wall rather than axially at the end, changing the dimension of outflow from end-oriented to wall-oriented. This allows lateral outflow without requiring the valve to protrude axially, thus reducing overall height while achieving the desired outflow direction.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a valve protrudes from the container body, then lateral outflow is enabled, but material cost and assembly complexity increase

Engineering Contradiction:

Improvelateral outflow capabilityVSAvoidassembly complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The valve is integrated into the end region of the container body, merging the valve structure with the container wall. The valve body is arranged substantially in the end region with only a collar-shaped upper section protruding, eliminating the need for a separate protruding valve assembly and reducing overall height while maintaining lateral outflow capability through the two outflow openings in the container wall.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The end region serves multiple functions: it provides the closure for the container opening, houses the integrated valve structure, and contains the connection geometry for media-tight coupling. This multi-functionality reduces the need for separate components and simplifies assembly while enabling lateral outflow through the wall-mounted outflow openings.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Length of stationary object

If the valve is integrated into the end region, then height and material cost are reduced, but media tightness must be maintained

Engineering Contradiction:

Improveoverall heightVSAvoidmedia tightness

Core Design Contradiction:

Length of stationary objectVSReliability

Solution Approach 1:

The valve is integrated into the end region of the container body, merging the valve structure with the container wall. The valve body is arranged substantially in the end region with only a collar-shaped upper section protruding, eliminating the need for a separate protruding valve assembly and reducing overall height while maintaining lateral outflow capability through the two outflow openings in the container wall.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

A connection geometry is provided on the outside of the wall surrounding the opening of the end piece, forming a media-tight connection with a corresponding further connection. This intermediary connection structure ensures media tightness between the integrated valve system and the external application, compensating for the integrated design while maintaining reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)
