Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication modes are established in the power supply apparatus, then the versatility and adaptability of the system is improved, but the complexity of mode selection and control increases
Solution Approach 1:
The communication mode is made dynamic and adjustable based on the operational mode of the power supply apparatus. The selection unit automatically switches between first communication mode (for power supply mode) and second communication mode (for authentication mode) depending on the current operational state, eliminating the need for manual configuration and simplifying the user interface while maintaining multiple communication capabilities
Solution Approach 2:
The system pre-configures multiple communication modes in advance, with each mode prepared and ready for selection based on the operational state. The selection unit is designed to automatically choose the appropriate pre-prepared mode based on simple criteria (power supply mode vs. authentication mode), reducing the complexity of real-time decision-making while ensuring proper communication protocol selection
2Ease of operation
If automatic mode selection is implemented, then the ease of operation is improved, but the reliability of power supply control may be compromised
Solution Approach 1:
The selection unit operates based on feedback from the operational mode detection mechanism. The control unit continuously monitors the operational state (power supply mode or authentication mode) and uses this feedback to automatically select the appropriate communication mode, ensuring that the selection is both automatic and reliable based on actual system state
Solution Approach 2:
The selection unit acts as an intermediary between the operational mode detection and the communication unit. It translates the operational state into the appropriate communication mode selection, ensuring that the automatic selection process maintains reliability by using clear, defined rules based on the current operational context
