Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If power modules are connected together to form complex electrical systems, then the system capability and power handling are improved, but the complexity of connecting cooling units and circulating heat transfer fluid increases
Solution Approach 1:
The cooling system is divided into modular cooling units, each with integrated cooling housing and fastening systems. Each power module can be independently cooled and then connected to form larger systems, reducing the overall complexity of cooling connections.
Solution Approach 2:
The cooling housing incorporates multiple fastening systems (first and second fastening systems) that can connect to different types of fittings and cooling units. This universal interface design allows the same cooling housing to connect to various cooling configurations, simplifying system integration.
2Reliability
If multiple cooling boxes are connected in parallel, then the cooling coverage and heat dissipation capacity are improved, but the number of connection parts and assembly complexity increase
Solution Approach 1:
Multiple fastening systems are integrated into a single cooling housing structure. The first and second fastening systems are combined with the cooling housing to form one unified component, reducing the total number of separate parts while enabling connections to multiple cooling units.
Solution Approach 2:
Fittings serve as intermediary components that simplify connections between cooling housings and cooling units. The fittings interface with the fastening systems, providing a standardized connection mechanism that reduces assembly complexity when connecting multiple cooling boxes in parallel.
3Adaptability or versatility
If modular cooling devices with interchangeable connectors are used, then the flexibility and scalability of the system are improved, but the manufacturing complexity and part variety increase
Solution Approach 1:
The first and second fastening systems are positioned asymmetrically on the cooling housing, with each serving specific connection purposes. This asymmetric arrangement provides flexible connection options while maintaining a standardized housing design that simplifies manufacturing.
Solution Approach 2:
The fastening systems are pre-integrated into the cooling housing during manufacturing, rather than being assembled separately. This preliminary integration reduces assembly complexity during system installation while maintaining manufacturing modularity and flexibility.
