Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connection devices are used for power supply conductor and phase conductors, then electrical connection reliability is improved, but assembly complexity and manufacturing cost increase
Solution Approach 1:
The patent combines separate connection devices for power supply conductors and phase conductors into a single integrated connection device. This merging reduces the number of components and simplifies assembly operations while maintaining reliable electrical connections between the voltage converter and electrical machine
2Reliability
If multiple separate connectors are used, then connection reliability is improved, but manufacturing cost increases
Solution Approach 1:
The patent integrates multiple separate connectors into a single connection device that handles both power supply conductors and phase conductors. This consolidation reduces manufacturing costs by eliminating the need to produce and assemble multiple separate connector components while maintaining reliable electrical connections
3Manufacturing precision
If multiple assembly steps are used for electrical connections, then connection precision is improved, but productivity decreases
Solution Approach 1:
The patent pre-integrates power supply conductors and phase conductors into a single connection device with all necessary connection elements already in place. This preliminary integration allows the entire electrical connection assembly to be installed in one step, improving productivity while maintaining connection precision through the pre-configured design
