Solution Overview

Problem

Mass flow control or valve units in coolant systems for hybrid or electric vehicles are complex, large, and lack variability options, requiring significant space and not allowing for flexible configuration of connection devices.

Innovation Solution

A compact mass flow control or valve unit design with a rotating valve body and fixed panel, where connecting devices are attached via an interface on one side of the housing, enabling modular configuration and alignment for optimized space use and flow efficiency, with radial seals for easy assembly and tolerance compensation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If connection devices are arranged on all sides of the housing, then flow distribution is optimized, but the device occupies excessive space and lacks compactness

Engineering Contradiction:
Improvedevice volumeVSAvoidconnection device configuration flexibility
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The connection devices are segmented and concentrated on one side of the housing rather than distributed all around it. This segmentation allows the device to maintain its functional versatility while achieving a compact, space-saving configuration by grouping connections in a localized area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection devices are arranged in a radial pattern around the valve body, utilizing the circular cross-sectional dimension of the housing. This dimensional arrangement allows multiple connections to be made on one side without increasing the device's axial length, achieving compactness while maintaining flow distribution capabilities.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If connection devices are integrally formed with the housing, then manufacturing is simplified, but adaptability to different applications is reduced

Engineering Contradiction:
Improveapplication-specific configurationVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection devices are separated from the housing as distinct, interchangeable components rather than being integrally formed. This segmentation enables different connection device configurations to be selected and attached to the same housing, providing application-specific adaptability without requiring multiple housing designs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The housing is designed with a universal interface that can accommodate various types of connection devices. This universal mounting structure allows a single housing design to serve multiple applications by simply changing the attached connection devices, achieving versatility without increasing structural complexity.

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

3Adaptability or versatility

If multiple sensors and valves are distributed throughout the coolant system, then temperature control of individual components is achieved, but the overall system complexity increases

Engineering Contradiction:
Improvecomponent-specific temperature controlVSAvoidnumber of sensors and valves
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mass flow control unit is designed as a universal device that can serve multiple components through its multiple connection devices. By consolidating what would otherwise require multiple separate valves and sensors into a single multi-functional unit, the system achieves component-specific temperature control while reducing overall system complexity.

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

Solution Approach 2:

The single mass flow control unit is segmented into multiple connection devices, each capable of connecting to different coolant system components. This segmentation within a unified structure allows the device to replace multiple distributed valves and sensors, reducing system complexity while maintaining the ability to control temperature for individual components.

Inventive Principle:
Principle #1Segmentation
