Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual checking methods are used to verify power supply allocation, then allocation accuracy can be ensured, but installation complexity and time consumption increase significantly
Solution Approach 1:
The system enables automatic self-identification of power supply allocations through signal feedback loops. Each power supply unit automatically transmits identification signals through the power conductors, and the controller automatically receives and processes these signals to determine the correct allocation, eliminating the need for manual verification procedures
Solution Approach 2:
The system implements feedback loops where identification signals are transmitted from power supply units through power conductors to remote devices, and return signals are transmitted back to the controller. This feedback mechanism enables automatic verification and confirmation of correct power supply allocation without manual intervention
2Reliability
If manual checking procedures are implemented to verify power supply-device correspondence, then installation errors can be detected, but installation time increases especially for distant devices
Solution Approach 1:
The system performs automatic self-testing and self-identification during the installation process. The controller automatically initiates signal transmission sequences and processes the responses to determine correct allocations, eliminating the time-consuming manual checking procedures that are particularly problematic for distant devices
Solution Approach 2:
The feedback loop mechanism enables rapid automatic verification of power supply allocations. The controller transmits test signals, receives return signals from remote devices, and automatically determines correctness of allocations, significantly reducing the time required compared to manual checking while maintaining high reliability
3Adaptability or versatility
If multiple power supply units are used to meet different device requirements, then system adaptability improves, but the risk of installation errors and improper allocation increases
Solution Approach 1:
The system uses feedback loops to automatically identify and confirm the correct allocation of each power supply unit to its corresponding remote device. The controller transmits identification signals through each power supply unit and analyzes the return signals to ensure proper matching, thereby maintaining high reliability even when multiple power supply units with different characteristics are used
Solution Approach 2:
Each power supply unit automatically participates in the identification process by transmitting and receiving signals. The system performs self-verification to ensure that power supplies with different characteristics are correctly allocated to devices requiring those specific characteristics, maintaining reliability while supporting system adaptability
