Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If two separate cooling systems are used for motor and driver, then heat dissipation function is provided, but manufacturing cost increases and space occupation increases
Solution Approach 1:
The patent merges the motor cooling system and driver cooling system into a single integrated cooling system. The water-cooled flow channel is designed to pass through both the motor housing and driver housing, allowing one cooling circuit to dissipate heat from both components simultaneously, thereby reducing system complexity and manufacturing cost while maintaining effective heat dissipation
2Temperature
If two separate cooling systems are used for motor and driver, then heat dissipation function is provided, but volume increases
Solution Approach 1:
The patent combines the motor and driver into a single integrated apparatus with a shared water-cooled flow channel. This merging of cooling functions into one system reduces the total volume required compared to having two separate cooling systems, while still providing adequate heat dissipation for both the motor and driver components
3Device complexity
If integrated cooling system is used, then manufacturing cost decreases and volume decreases, but heat-dissipation efficiency must be maintained
Solution Approach 1:
The patent applies local quality by providing dedicated cooling sections within the integrated flow channel for both the motor and driver. The water-cooled flow channel includes a motor-cooling section and a driver-cooling section, ensuring that each component receives targeted cooling attention, thereby maintaining high heat-dissipation efficiency despite the simplified integrated structure
