Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If contactors and shunts are added to power supply for secondary loads, then load control capability is improved, but system volume and costs increase
Solution Approach 1:
The patent extracts the contactor and shunt components from the traditional power distribution architecture. Instead of using physical contactors to switch loads, the system uses a monitoring module to detect load states and a power supply module to control power delivery, thereby eliminating the need for bulky contactor components while maintaining load control capability.
Solution Approach 2:
The patent replaces the mechanical contactor-based power switching system with an electronic control system. The monitoring module detects load states and communicates with the power supply module, which then controls power delivery electronically, substituting mechanical contactor operations with electronic signal processing and controlled power supply.

3Adaptability or versatility
If more contactors and shunts are configured for increasing secondary loads, then power distribution flexibility is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal power supply control architecture where the power supply module can serve multiple secondary loads through a single unified control interface. The monitoring module detects states of all connected loads, and the power supply module responds to control signals to manage power distribution to any combination of loads, providing multi-functional power control without requiring separate contactors for each load.
Solution Approach 2:
The patent extracts the contactor and shunt components from the traditional power distribution architecture. Instead of using physical contactors to switch loads, the system uses a monitoring module to detect load states and a power supply module to control power delivery, thereby eliminating the need for bulky contactor components while maintaining load control capability.

AI summary
A communication power supply system (10) includes an alternating current power distribution module (105), a rectifier module (104), a monitoring module (103), a direct current power distribution module (101), and a signal-driven collection board (102). The monitoring module (103) sends a control signal to the direct current power distribution module (101) by using the signal-driven collection board (102), where the control signal is used to control closing or opening of a circuit in the direct current power distribution module (101). The communication power supply system (10) uses the monitoring module (103) to control the direct current power distribution module (101), to control whether to power on loads connected to the direct current power distribution module (101). In this way, configuration of a contactor and a shunt in the communication power supply system (10) is omitted, thereby effectively reducing a volume of the communication power supply system (10) and reducing costs of the communication power supply system (10).
