Solution Overview

Problem

Existing valve regulating devices for fluid flow in air intake systems face issues with poor seal in the closed state and complex control mechanisms, as well as difficulties in installation and maintenance, especially when multiple devices are used simultaneously.

Innovation Solution

A valve regulating device with a support body featuring a dual-segment seal, where one segment is compressively stressed and the other is flexurally stressed, providing optimal tightness and simplicity in design, and a control pin system that allows for rotational locking and guided mounting, reducing flow disruption and enhancing seal effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single seal is used in the support body, then the device structure is simple, but the seal effectiveness is poor

Engineering Contradiction:
Improveseal effectivenessVSAvoidseal structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The seal is divided into two distinct functional segments: a first functional segment and a second functional segment. Each segment is positioned at different locations on the support body and engages with different portions of the valve body, creating multiple sealing points that work together to improve overall seal effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each functional segment of the seal is designed with specific local properties tailored to its position and function. The first functional segment has different characteristics than the second functional segment, allowing each to optimize its sealing performance at its specific location on the support body.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If the valve body is displaced in the closure position, then play in the control means can be taken up, but tightness is compromised

Engineering Contradiction:
Improveplay absorptionVSAvoidtightness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control pin is designed to preliminarily absorb play and positioning variations in the control means before the valve body reaches its final closure position. This preliminary action ensures that when the valve body engages with the seal, all play has already been taken up, guaranteeing tightness without compromising ease of operation.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a cartridge valve device is used, then effective seal is provided, but installation becomes awkward and precise mounting is required

Engineering Contradiction:
Improveseal effectivenessVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The valve device is segmented into modular components: the support body with integrated seal segments, the valve body, and the control pin. This segmentation allows each component to be manufactured separately and assembled in a simplified sequence, reducing installation complexity while maintaining seal effectiveness.

Inventive Principle:
Principle #1Segmentation

4Reliability

If the seal is attached to the outer circumference of the valve body, then the valve can be sealed, but the seal is constantly exposed to the flow

Engineering Contradiction:
Improveseal functionVSAvoidflow exposure
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Instead of attaching the seal to the outer circumference of the valve body where it would be exposed to flow, the seal is inverted and attached to the support body structure. The functional segments are positioned to engage with the valve body from the support body side, reversing the traditional seal arrangement and protecting the seal from direct flow exposure while maintaining its sealing function.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

A valve regulating device intended to regulate the circulation of a fluid in the region of an opening, said device consisting of a pivoting valve body, of an annular support body integrating two opposing bearings mounting said valve body in a rotational manner, and of a control pin, wherein said valve body may be displaced in rotation between a totally open position and a closed position, in which it rests against the annular seat provided by the support body; the support body is provided with a seal with a first extending functional segment and a second extending functional segment having protruding lateral extensions, for example in the form of ribs, on the face of the support body that bears against the edge of the opening, said extensions also being interconnected by intermediate joining portions, which also extend in a protruding manner over the bodies of the two opposing bearings so as to provide a continuous peripheral seal around the opening when the regulating device is mounted on said opening.
