Solution Overview

Problem

Current valve arrangements for exhaust gas turbocharger cooling systems face challenges with mechanical stress, increased space requirements, and material costs due to external clamps and oversized valves, which also lead to potential backflow and flow around issues.

Innovation Solution

A valve arrangement where the valve body is supported on a connection that is harder than the coolant hose, allowing for a blocking or throttling function, with the valve body being positioned in the blocking direction to prevent movement and eliminate the need for external clamps, featuring conical or corrugated designs to secure the hose and prevent backflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an external clamp is used to fix the valve body, then the valve body is secured against movement, but the space required and material costs increase

Engineering Contradiction:

Improvevalve body positioning stabilityVSAvoidspace requirement

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The connection is designed to integrate both the hose connection function and the valve body support function into a single component. The connection serves as both the interface for the coolant hose and the support structure for the valve body, eliminating the need for separate clamps or mounting brackets.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connection is designed as a multi-functional component that simultaneously performs hose attachment, valve body support, and positioning functions. This universal design reduces the total number of parts needed in the valve arrangement.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If an external clamp is used to fix the valve body, then the valve body is secured against movement, but material costs increase

Engineering Contradiction:

Improvevalve body positioning stabilityVSAvoidmaterial cost

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

Solution Approach 2:

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If an external clamp is used to fix the valve body, then the valve body is secured against movement, but mechanical stress on components increases

Engineering Contradiction:

Improvevalve body positioning stabilityVSAvoidmechanical stress on components

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connection features a conical geometry that distributes mechanical loads more evenly. The tapered shape allows for gradual stress distribution rather than concentrated stress points, reducing peak stresses on the valve body and hose assembly.

Inventive Principle:

Principle #14Spheroidality (Curvature)

4Reliability

If a larger diameter valve is used to prevent movement, then the valve body is secured against movement, but the flow around the valve increases at higher pressures

Engineering Contradiction:

Improvevalve body positioning stabilityVSAvoidflow around valve

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The arrangement has a connector (1) for a cooling medium hose, and a valve comprising a valve body (2), where cooling medium flows through the valve body. The valve body is supported at the connector and connected with the connector in a force-fit and/or form-fit manner. The connector has a cylindrical casing surface (13) on which the hose is arranged, such that an inner circumference of the hose stays in contact with an outer circumference of the connector and/or the valve body. The valve body is connected with a cooling medium circuit of a motor vehicle engine over the connector.
