Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wiring methods are used in charging devices, then power transmission can be achieved, but the internal wiring becomes complex and safety decreases
Solution Approach 1:
The charging device is divided into modular components (charging apparatus and charging device) with standardized interfaces. The charging apparatus contains integrated AC-DC conversion, DC-DC conversion, and power allocation functions in separate modules that connect through simplified interfaces, reducing overall wiring complexity while maintaining safety through modular isolation
Solution Approach 2:
A power allocation board serves as an intermediary component between DC-DC modules and output terminals. This board集中 manages power distribution through switches, simplifying the wiring architecture by providing a centralized control point rather than direct connections from each DC-DC module to multiple outputs
2Ease of manufacture
If traditional charging device design is used, then charging function is provided, but costs are high
Solution Approach 1:
The charging apparatus is designed with universal modules that can perform multiple functions. The DC-DC modules can serve different output requirements, and the power allocation board can dynamically distribute power to multiple terminals, reducing the need for dedicated components for each function and lowering overall costs
Solution Approach 2:
The system uses controllable switches on the power allocation board to dynamically change power distribution parameters. By adjusting switch states, the same hardware configuration can adapt to different charging requirements, reducing the need for multiple fixed configurations and lowering manufacturing costs
3Adaptability or versatility
If multiple DC-DC modules are used to meet diverse charging requirements, then power utilization improves, but wiring complexity increases
Solution Approach 1:
Multiple DC-DC modules are merged into a unified system through the power allocation board. The board combines the output of multiple modules and distributes them to various terminals, allowing diverse charging requirements to be met while maintaining simplified wiring through centralized power management

AI summary
This application provides a charging apparatus and a charging device. The charging apparatus includes a plurality of alternating current to direct current conversion AC-DC modules, a plurality of direct current to direct current conversion DC-DC modules, and a power allocation board. The AC-DC module is configured to convert an alternating current into a direct current. The DC-DC module is configured to perform voltage conversion on the direct current output by the AC-DC module. The DC-DC module includes first output ports. The power allocation board includes input terminals, a plurality of switches, and a plurality of second output ports. The plurality of switches are configured to allocate an output power of at least one DC-DC module to at least one of the second output ports. The first output port of the DC-DC module is configured to be in a plug-in connection to the input terminal of the power allocation board. The first output ports are in the plug-in connection to the input terminals, so that an output power of the DC-DC module can be transmitted to the power allocation board. This can avoid wiring between the power allocation board and a conversion unit, and safety is high.
