Engineering Contradiction Analysis
1Reliability
If separate sensor module voltage supply and cabling are used, then reliable power supply is achieved, but system weight and costs increase
Solution Approach 1:
The patent integrates the voltage supply unit directly into the control device, merging previously separate components (voltage supply unit and cabling) with the control device. This consolidation eliminates the need for separate sensor module voltage supply and cabling, thereby reducing system weight while maintaining power supply reliability through the integrated design.
2Power
If separate sensor module voltage supply and cabling are used, then power delivery is ensured, but system costs increase
Solution Approach 1:
The voltage supply unit is integrated into the control device, reducing the number of separate components and assembly steps. This merging of functions decreases manufacturing complexity and system cost while ensuring adequate power delivery capability to sensor modules through the integrated power supply design.
3Speed
If high-bandwidth communication links are used for sensor data transmission, then data transmission speed is improved, but susceptibility to electromagnetic interference increases
Solution Approach 1:
The patent extracts the voltage supply function from separate cabling and integrates it directly into the control device. This eliminates long transmission lines that are susceptible to electromagnetic interference, thereby reducing harmful electromagnetic effects while maintaining high-bandwidth data transmission capabilities through optimized internal connections.
