Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the drive module is disposed in the electric control chamber without adequate heat dissipation, then the integration and space utilization are improved, but the operation stability of the drive module deteriorates due to heat accumulation
Solution Approach 1:
A radiator is introduced as an intermediary component between the drive module and the electric control chamber environment. The radiator provides a dedicated heat dissipation pathway, allowing the drive module to be integrated in the electric control chamber while maintaining operational stability through effective thermal management.
2Device complexity
If the drive module and main control module are integrated at one circuit board, then the device complexity is reduced, but the heat dissipation efficiency of the drive module deteriorates
Solution Approach 1:
The electric control chamber is divided into distinct functional regions: one area for the integrated drive module and main control module on the circuit board, and another area with radiator fins dedicated to heat dissipation. This segmentation allows the circuit board integration to be maintained while providing separate, optimized heat dissipation pathways.
3Object-affected harmful factors
If the electric control chamber is sealed to protect components, then the protection against external factors is improved, but the heat dissipation capability deteriorates
Solution Approach 1:
The electric control chamber uses a sealed enclosure structure with integrated radiator fins that extend through or beyond the chamber walls. This flexible design maintains the protective sealing of the chamber while providing dedicated thermal pathways through the radiator structure, allowing heat dissipation without compromising component protection.
