Solution Overview

Problem

Conventional vehicle cooling systems are complex to integrate due to the varied positions of cooling system components, requiring separate installation spaces and making assembly challenging.

Innovation Solution

A modular cooling module with a housing containing interface units for a coolant container, pump unit, filter unit, and heat exchange unit, allowing for universal and flexible installation by accommodating all necessary components within a compact design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cooling system components are arranged in varied positions within the vehicle, then each component can be optimally positioned for its function, but the integration becomes complex and requires separate installation spaces

Engineering Contradiction:
Improvefunctional positioningVSAvoidintegration complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple cooling system components (coolant container, pump unit, filter unit, heat exchange unit) into a single integrated cooling module housing. This merging approach maintains the functional positioning benefits of separate components while eliminating the integration complexity by pre-assembling them in a standardized configuration that can be installed as one unit.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cooling module housing is designed with multiple interface units that can accommodate different component configurations, making the housing universal for various cooling system arrangements. This allows the same housing design to serve multiple functions and adapt to different vehicle types without requiring custom integration for each configuration.

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

2Ease of manufacture

If cooling system components are integrated into a modular housing, then assembly becomes easier and space is saved, but the housing design must accommodate multiple component interfaces

Engineering Contradiction:
Improveassembly easeVSAvoidhousing design complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The housing is segmented into multiple interface units, each designed to receive a specific cooling component. This segmentation allows for standardized, modular assembly where components can be independently manufactured and then integrated into the housing through predefined interfaces, simplifying the overall assembly process despite the multi-functional requirements.

Inventive Principle:
Principle #1Segmentation

3Volume of moving object

If a compact cooling module design is used, then space is saved and universal installation is enabled, but component accessibility for maintenance may be reduced

Engineering Contradiction:
Improvespace efficiencyVSAvoidcomponent accessibility
Core Design Contradiction:
Volume of moving objectVSEase of repair

Solution Approach 1:

The cooling components are nested within the housing in a compact arrangement, with each component positioned within the volume of the housing. This nesting achieves space efficiency while maintaining accessibility through strategically placed interface units that allow service personnel to reach and service components without completely disassembling the housing.

Inventive Principle:
Principle #7Nested doll (Nesting)
