Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple discrete components are used for thermal management, then thermal management functionality is achieved, but space occupancy and cost increase

Engineering Contradiction:
Improvethermal management functionalityVSAvoidfront compartment space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent integrates multiple discrete thermal management components (pumps, valves, heat exchangers, radiators) into a single integrated thermal management unit. This merging of components reduces the total space occupancy in the front compartment while maintaining all necessary thermal management functionalities for the battery, motor, and passenger compartment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated thermal management unit performs multiple functions simultaneously - it manages battery thermal, motor thermal, passenger compartment heating and cooling, and defrosting/defogging. This multi-functionality is achieved through a unified structure with shared components and multiple flow paths, eliminating the need for separate discrete systems.

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

2Adaptability or versatility

If multiple discrete components are used for thermal management, then thermal management functionality is achieved, but the number of pipelines and brackets increases

Engineering Contradiction:
Improvethermal management functionalityVSAvoidnumber of pipelines and brackets
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple discrete components into one integrated unit with internal flow channels. This eliminates the need for numerous external pipelines connecting separate components and reduces the number of mounting brackets required, thereby simplifying the overall system structure.

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If components are integrated on a flow channel plate, then space and pipelines are reduced, but manufacturing complexity may increase

Engineering Contradiction:
