Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power feed switching control circuit is reset by stopping the system, then the circuit can be properly restarted and reset, but the system operation is interrupted and communication may be disrupted
Solution Approach 1:
The patent segments the reset function from the main system operation by introducing a dedicated automatic reset circuit that operates independently. This reset circuit is triggered by a reset signal that is separated from the normal power feed switching control, allowing the control circuit to be reset without stopping the entire system. The segmentation enables independent reset operation while maintaining system continuity.
Solution Approach 2:
The patent introduces an intermediary reset signal mechanism that mediates between the system operation and the control circuit reset. The reset signal acts as an intermediary that can trigger the automatic reset circuit without requiring system shutdown. This intermediary mechanism allows the control circuit to be reset while the system continues to operate, resolving the contradiction between reliable reset and system continuity.
2Ease of repair
If a fault occurs in the power feed switching control circuit, then the circuit needs to be reset, but traditional reset methods require system shutdown which causes communication breakdowns
Solution Approach 1:
The patent implements a self-service reset mechanism where the automatic reset circuit autonomously resets the power feed switching control circuit when a fault is detected, without requiring external intervention or system shutdown. The reset circuit monitors the control circuit state and automatically triggers the reset operation, enabling the system to self-correct faults while maintaining continuous operation and avoiding communication disruptions.
Solution Approach 2:
The patent prepares the automatic reset circuit in advance so that when a fault occurs in the power feed switching control circuit, the reset function is already in place and can be immediately activated. This preliminary preparation ensures that the reset can be performed quickly and efficiently without requiring system shutdown, thereby preventing communication disruptions while maintaining ease of repair.
