Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional configuration interfaces and programming methods are used for industrial safety relays, then the relay can perform safety monitoring functions, but the configuration process becomes complex and difficult to interpret and troubleshoot as the number of terminals grows
Solution Approach 1:
The configuration interface is segmented into functional blocks representing different safety relay terminals and their functions. Each function block can be independently configured, visualized, and troubleshooted, breaking down the complex overall configuration into manageable segments that are easier to interpret and manage as the number of terminals increases.
Solution Approach 2:
A graphical user interface acts as an intermediary between the user and the complex relay configuration. This interface provides visual representation and simplified interaction methods, mediating the complexity of terminal configurations and making the system easier to understand and manage without reducing the underlying safety monitoring functionality.
2Adaptability or versatility
If more safety relay terminals are added to handle complex safety monitoring requirements, then the monitoring capability improves, but the difficulty to interpret and troubleshoot the configuration increases
Solution Approach 1:
The graphical interface uses color coding to represent different states, functions, and alert conditions of safety relay terminals. This visual differentiation makes it easier to quickly identify and troubleshoot issues in complex configurations with many terminals, as users can visually distinguish between normal operation, warnings, and error states without interpreting complex text-based configurations.
Solution Approach 2:
The configuration is represented in a graphical dimension rather than text-based or tabular formats. This spatial visualization allows users to perceive relationships and states of multiple terminals simultaneously, making troubleshooting easier even as the number of terminals grows, by providing an intuitive visual map of the safety monitoring system.
3Adaptability or versatility
If comprehensive configuration options are provided for each safety relay terminal, then the system can handle diverse safety requirements, but the user training time and operational complexity increase
Solution Approach 1:
The system provides pre-configured function blocks with common safety relay terminal settings and configurations. Users can start with these pre-prepared templates and modify them as needed, rather than building configurations from scratch. This preliminary preparation reduces the operational complexity and training required while maintaining the ability to handle diverse safety requirements through customization.
Solution Approach 2:
The graphical function block interface serves multiple functions: configuration, visualization, monitoring, and troubleshooting all in one unified system. This multi-functionality consolidates what would otherwise require multiple separate tools or interfaces, making the system easier to operate and reducing training requirements while maintaining comprehensive configuration flexibility for diverse safety applications.
