Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electric drive systems use separate modules with external interconnections, then system flexibility is improved, but device complexity and installation time increase
Solution Approach 1:
The patent combines the dual converter and diode bridge into a single integrated module, eliminating external interconnections between separate components. This merging reduces device complexity while maintaining configuration flexibility through the integrated design that can be switched between different drive configurations.
2Adaptability or versatility
If traditional electric drive systems use separate modules with external interconnections, then configuration adaptability is improved, but installation time increases
Solution Approach 1:
By integrating the dual converter and diode bridge into one module, the patent eliminates the need for external interconnections that would require time-consuming installation. The integrated design allows configuration changes to be made through internal switching rather than physical reconnection of external components.
3Adaptability or versatility
If traditional electric drive systems use separate modules with external interconnections, then modularity is improved, but reliability decreases
Solution Approach 1:
The integration of dual converter and diode bridge into a single module eliminates external interconnections, which are potential failure points. By removing these external connection points, the patent improves reliability while maintaining modularity through the integrated module design that can be configured for different drive systems.
