Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual DIP switch configuration is used for hardware addresses, then each output circuit can be uniquely identified, but the configuration process becomes cumbersome and error-prone
Solution Approach 1:
The system automatically detects which output circuit is connected to which output path and configures the hardware address without manual intervention. The control circuit enables each output circuit in turn, detects which output path receives the signal, and automatically assigns the corresponding hardware address, making the system self-configuring.
Solution Approach 2:
The patent replaces the mechanical DIP switch system with an automatic detection and configuration system. Instead of manually setting physical switches, the control circuit uses signal detection and software logic to determine connections and assign addresses automatically.
2Adaptability or versatility
If manual hardware address configuration is implemented, then output circuits can be controlled individually, but maintenance skill requirements increase and errors occur
Solution Approach 1:
The system performs self-identification and self-addressing. When an output circuit is enabled, the system detects which output path receives the signal and automatically assigns the appropriate hardware address, eliminating the need for maintenance personnel to manually configure addresses or have specialized knowledge.
3Reliability
If DIP switches are used for hardware address configuration, then hardware addresses can be set, but device complexity and production costs increase
Solution Approach 1:
The patent extracts and eliminates the DIP switches from the output circuit. The hardware address configuration function is moved from a physical component (DIP switches) to a software-based automatic detection and assignment system in the control circuit.
Solution Approach 2:
The mechanical DIP switch system is replaced with an electronic detection and software configuration system. The control circuit uses signal detection and programming to assign hardware addresses, eliminating the need for physical configuration components.
