Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage batteries with different rating voltage specifications adapt to different emergency power supplies, then the power supply can provide dedicated voltage output, but compatibility is reduced and resources are wasted
Solution Approach 1:
The emergency power supply is designed with multiple energy storage modules (first energy storage module and second energy storage module) that can be connected in different configurations. The switching circuit enables the same power supply device to output multiple voltage specifications (12V and 24V) by selectively connecting energy storage modules in series or parallel, making a single device compatible with both 12V gasoline engines and 24V diesel engines.
Solution Approach 2:
The power supply system is divided into separate energy storage modules that can be independently connected or disconnected. The first energy storage module and second energy storage module are segmented units that can be selectively activated based on the required voltage output, allowing flexible configuration without requiring a completely different power supply for each voltage specification.
2Power
If multiple energy storage modules are connected in series to provide higher voltage, then voltage output is increased, but the system complexity increases
Solution Approach 1:
The system employs a dynamic switching mechanism controlled by a controller that automatically detects the required voltage output and configures the energy storage module connections accordingly. The switching circuit dynamically reconfigures the series/parallel connections of energy storage modules based on real-time voltage requirements, eliminating the need for manual configuration and reducing operational complexity despite the multiple module design.
Solution Approach 2:
A switching circuit acts as an intermediary between the multiple energy storage modules and the output terminal. This intermediary component manages the complex connection logic by providing standardized connection interfaces and automated switching control, simplifying the overall system operation while enabling flexible voltage output configurations.
3Device complexity
If the power supply device provides fixed voltage output, then the circuit design is simplified, but adaptability to different voltage requirements is reduced
Solution Approach 1:
The power supply device incorporates dynamic voltage selection capability through automated detection circuits and switching mechanisms. The controller detects the target voltage requirement and automatically configures the energy storage module connections to provide the appropriate voltage output, enabling the system to adapt between 12V and 24V specifications without requiring separate dedicated circuits for each voltage level.
