Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a plastic fluid hub is used to mount components, then packaging space is reduced, but mechanical strength and reliability deteriorate due to material failure

Engineering Contradiction:
Improvepackaging spaceVSAvoidmechanical strength
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The patent merges the fluid hub structure with the heat exchanger by integrating the plastic fluid hub directly onto the heat exchanger body, eliminating the need for separate mounting brackets and reducing overall packaging space. This combination allows compact arrangement while distributing mechanical loads across both components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heat exchanger serves dual functions: thermal exchange and structural support for mounting the fluid hub and other components. This multi-functionality reduces the need for additional structural components, saving space while maintaining mechanical strength through proper design of the heat exchanger's mounting surfaces.

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

2Ease of manufacture

If plastic welding is used to join fluid hub components, then manufacturing is simplified, but reliability deteriorates due to welding failure

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidjoint reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces intermediary elements such as reinforcement ribs, mounting flanges, and separate mounting brackets that are either injection-molded as single pieces with the fluid hub or attached through more reliable methods. These intermediaries distribute stresses away from the plastic welding joints, preventing failure while maintaining ease of manufacture.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple connectors are used in fluid flow circuits, then component mounting is flexible, but pressure drop increases

Engineering Contradiction:
Improvemounting flexibilityVSAvoidpressure drop
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent merges multiple fluid flow passages and connectors into an integrated plastic fluid hub with built-in channels and ports. This consolidation reduces the number of separate connectors and joints in the fluid circuit, minimizing pressure drops while maintaining flexible component mounting capabilities through the hub's multiple connection points.

Inventive Principle:
Principle #5Merging (Combining)
