Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DC power supply devices are installed for single-use applications, then the device configuration is simple and reliable, but the adaptability to different applications is poor and requires complex revisions when reused
Solution Approach 1:
The patent implements a universal DC power supply device that can serve multiple applications through configurable connection interfaces. The system includes standardized connection terminals and control interfaces that allow the same device to be adapted to different power supply scenarios without requiring complete reconfiguration, thereby improving versatility while controlling complexity through modular design
Solution Approach 2:
The patent employs dynamic connection configuration where the power supply device can change its operational parameters and connection states based on the specific application requirements. The control apparatus enables real-time adjustment of connection settings, allowing the system to adapt dynamically between different use cases without physical reconfiguration
2Power
If multiple DC power supply devices are connected in parallel to ensure high output power, then the power output is sufficient and reliable, but the complexity of reconfiguration increases when changing applications
Solution Approach 1:
The patent divides the power supply system into modular segments where each DC power supply device operates as an independent unit with standardized interfaces. This segmentation allows devices to be connected in parallel through uniform connection protocols, reducing reconfiguration complexity when changing applications while maintaining the ability to scale power output by adding or removing modules
Solution Approach 2:
The patent implements parameter-based configuration where the operational characteristics of parallel-connected devices are adjusted through configurable parameters rather than physical reconfiguration. The control apparatus manages parallel connections by modifying electrical parameters such as voltage distribution and current allocation, enabling easy adaptation when changing applications while maintaining high power output
3Reliability
If power generation facilities remain stopped when necessary power falls below total power generation amount, then the system operates reliably within capacity limits, but the productivity and effective utilization of power generation facilities is reduced
Solution Approach 1:
The patent implements dynamic power generation management where the operational status of power generation facilities is continuously adjusted based on real-time power demand. The control apparatus monitors necessary power levels and dynamically activates or deactivates generation facilities, enabling the system to maintain reliability within capacity limits while maximizing productivity by utilizing available facilities when demand fluctuates
Solution Approach 2:
The patent employs feedback control mechanisms where the control apparatus continuously monitors power demand and generation capacity, using this information to optimize the operational status of power generation facilities. The system receives feedback on power levels and adjusts facility activation accordingly, ensuring reliable operation within capacity while improving effective utilization by activating facilities when demand warrants their use
