Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication protocol is used for communication between the electrical unit and battery unit, then the device complexity is reduced, but the reliability deteriorates due to interference from operating conditions or charging environments
Solution Approach 1:
The system changes communication parameters by switching between different communication protocols based on detected interference levels. When interference is detected in the first communication protocol, the system transitions to a second communication protocol with different parameters (such as different frequency, modulation scheme, or data rate) that is more suitable for the current electromagnetic environment, thereby maintaining communication reliability.
Solution Approach 2:
The communication system transitions from a static single-protocol approach to a dynamic multi-protocol system that can adaptively switch between protocols based on real-time interference detection. This dynamic adjustment allows the system to optimize communication reliability according to changing operating conditions during charging or discharging operations.
2Reliability
If communication protocol switching is implemented to improve anti-interference capability, then the reliability is improved, but the device complexity increases due to multiple protocols and switching control
Solution Approach 1:
The system implements a feedback mechanism where the communication control unit continuously monitors the quality of communication in the first protocol and automatically triggers a switch to the second protocol when interference is detected. This feedback-based automatic switching reduces the need for complex manual control mechanisms while maintaining high reliability.
Solution Approach 2:
The communication control unit acts as an intermediary that manages the switching between different communication protocols. It detects interference conditions and coordinates the protocol switching between the electrical unit and battery unit, simplifying the overall control architecture by centralizing the switching logic in a dedicated control component.
3Productivity
If manual restart is performed when communication is interrupted, then the ease of operation is maintained, but the productivity deteriorates due to operation interruptions and potential persistent interference
Solution Approach 1:
The communication system performs self-service by automatically detecting communication interference and switching protocols without requiring manual intervention. The communication control unit monitors communication quality and autonomously transitions between protocols to maintain uninterrupted charging or discharging operations, eliminating the need for manual restarts and improving overall productivity.
Solution Approach 2:
The system ensures continuous communication and uninterrupted charging/discharging operations by proactively switching protocols before communication failure occurs. When interference is detected in the first protocol, the system transitions to the second protocol, maintaining the continuity of useful action (charging/discharging) without interruption or manual intervention.
