Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If various cooling system components are individually arranged and connected in an eco-friendly vehicle, then each component can be independently controlled and maintained, but the layout space requirement increases, assembly time increases, and hose routing becomes complex

Engineering Contradiction:
ImproveIndependent control and maintenance capabilityVSAvoidLayout complexity and assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple cooling system components (coolant pump, control valve, radiator, battery thermal management components) into a single integrated coolant control module. This merging reduces the number of separate parts that need to be arranged and connected, simplifying the overall system layout while maintaining the functional capabilities of each individual component through modular design elements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated coolant control module is designed to perform multiple functions simultaneously - cooling the engine, cooling the battery, and managing thermal conditions for various power electronics. The module uses a single coolant circulation system with strategically placed outlets and passages to serve multiple thermal management needs, reducing the requirement for separate cooling circuits.

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

2Adaptability or versatility

If multiple separate components are used for cooling system, then functional flexibility is improved, but the number of parts increases and assembly time increases

Engineering Contradiction:
ImproveFunctional flexibilityVSAvoidAssembly time and installation efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

Multiple cooling system components are merged into a single integrated module that can be installed as one unit in the vehicle. The module includes internally connected coolant passages, mounted pumps, and integrated control valves, eliminating the need for separate installation and connection of multiple individual components while maintaining functional flexibility through internal routing options.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cooling system components are pre-assembled and pre-configured into a complete module before vehicle assembly. Coolant passages are pre-routed, connections are pre-established, and the entire assembly is tested as a unit, significantly reducing on-vehicle assembly time and installation complexity.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If complex hose routing is used to connect cooling components, then all components can be connected, but flow resistance increases and pump load increases

Engineering Contradiction:
ImproveComponent connectivityVSAvoidPump load and flow resistance
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

By integrating multiple components into a single module with internally connected passages, the patent eliminates long external hose routes. The coolant flows through short, direct passages between components within the module, significantly reducing flow resistance and the energy required by the pump to maintain circulation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the coolant circulation function from complex external hose routing and relocates it to internal passages within the integrated module. This extraction of the flow path from the external environment to the internal structure of the module simplifies the routing and reduces flow resistance.

Inventive Principle:
Principle #2Taking out (Extraction)
