Solution Overview

Problem

Existing check valves in hydraulic and thermo-hydraulic systems face issues with increased production costs and reduced operational reliability due to the need for multiple components and openings, which can lead to fluid leakage and complex assembly processes.

Innovation Solution

A check valve design featuring a valve body with internal projections for engaging a connection element and shutter, allowing for a minimal number of components and openings, and an efficient assembly process using a cap and sealing ring to prevent leakage, with the connection element being easily removable and deformable for engagement within the valve body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a pin is used to pivotally engage the shutter to the valve body from outside, then the shutter can be securely mounted, but the number of components increases and production costs increase

Engineering Contradiction:
Improveshutter mounting securityVSAvoidnumber of components
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The connection element integrates multiple functions into a single component: it serves as both the pivotally mounted connection to the valve body and the support for the shutter. The L-shaped configuration combines the connection arm (with projection for valve body engagement) and the support arm (for shutter engagement) into one piece, eliminating the need for separate pin and support components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connection element performs multiple functions simultaneously: it provides pivotal engagement with the valve body, supports the shutter, and enables both assembly and disassembly operations through its deformable base portion. This multi-functional design reduces the overall component count while maintaining structural integrity.

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

2Strength

If a pin with seals is used to pivotally engage the shutter, then the shutter can be securely mounted, but the number of sealing stages increases and operational reliability decreases

Engineering Contradiction:
Improveshutter mounting securityVSAvoidoperational reliability
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The harmful sealing components (seals and sealing stages) are completely removed from the pivotal engagement mechanism. The connection element achieves secure mounting through mechanical engagement of its projection with the valve body and its support arm with the shutter, eliminating the need for any sealing elements at the pivotal connection points.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If multiple components and openings are used in the valve design, then the shutter can be mounted, but the assembly process becomes complex and production costs increase

Engineering Contradiction:
Improveassembly simplicityVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The connection element merges multiple previously separate components (pin, support structure, mounting mechanism) into a single integrally formed piece with L-shaped configuration. This consolidation dramatically simplifies the assembly process while reducing the total number of components that need to be manufactured and assembled.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of manufacture

If a hook with multiple openings is used to support the shutter, then the shutter can be mounted, but the constructive complexity increases

Engineering Contradiction:
Improveshutter mounting capabilityVSAvoidconstructive complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The connection element combines the mounting function and shutter support function into a single L-shaped structure. The first arm provides the mounting connection to the valve body while the second arm supports the shutter, eliminating the need for separate hook and support components with multiple openings.

Inventive Principle:
Principle #5Merging (Combining)
