Solution Overview

Problem

Conventional thermal management modules face issues with complex and time-consuming assembly of gaskets, misplacement of loose components, and frequent leakage due to inefficient sealing between the actuator housing, pump housing, and fluid machines, leading to pressure drops and reliability concerns.

Innovation Solution

The integration of gaskets with the fluid hub housing and other components, such as the actuator and pump housings, through over-molding or 'cured in place' methods, ensures a reliable and efficient sealing connection, reducing the number of loose components and minimizing leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If gaskets are used as separate components between actuator housing, pump housing, and fluid hub housing, then sealing connection can be formed, but assembly becomes complex and time-consuming

Engineering Contradiction:
Improvesealing connection reliabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The gasket is integrally formed with the actuator housing as a unified component, eliminating the need for separate gasket installation. The actuator housing now includes the gasket as an integrated sealing element that forms the sealing connection between the actuator housing and fluid hub housing during assembly, significantly simplifying the assembly process while maintaining reliable sealing.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If gaskets are used as loose components, then sealing can be achieved, but misplacement and displacement occur frequently

Engineering Contradiction:
Improvesealing connection reliabilityVSAvoidassembly ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The gasket is merged into the actuator housing as an integrated component, eliminating the issues of misplacement and displacement. The sealing connection is now formed by the integrated gasket structure that is permanently attached to the actuator housing, ensuring proper positioning and eliminating the need for manual gasket handling during assembly.

Inventive Principle:
Principle #5Merging (Combining)
