Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If calibration signals are read and written through manual database operations (dragging signals to windows), then the system maintains simple structure, but the operational efficiency and functionality are limited
Solution Approach 1:
The patent introduces mapping system variables as an intermediary layer between the calibration database and the user interface. These variables automatically map to calibration signals, enabling efficient reading and writing operations without manual database manipulation. The mapping variables serve as mediators that translate user actions into database operations, significantly improving productivity while maintaining manageable system complexity through automated variable management.
2Adaptability or versatility
If calibration signals are used as variables for mathematical operations, then the functionality and adaptability are improved, but the system complexity increases
Solution Approach 1:
The patent makes calibration signals universally usable as variables across multiple functions. By creating mapping system variables that represent calibration signals, the system enables these signals to be used in mathematical operations, curve drawing, and modifications just like any other system variable. This multi-functionality approach allows calibration signals to participate in diverse operations without requiring separate handling mechanisms for each operation type.
Solution Approach 2:
The patent creates copies of calibration signals in the form of mapping system variables. These variable copies can be freely used in mathematical operations and modifications without affecting the original calibration signal definitions in the database. The copying mechanism allows complex operations on signal representations while the actual calibration data remains intact and manageable in the database structure.
3Ease of operation
If automatic mapping variables are created for calibration signals, then the ease of operation is improved, but the initial setup complexity increases
Solution Approach 1:
The system implements self-service through automatic mapping variable creation. When calibration signals are imported or defined, the system automatically generates corresponding mapping system variables without requiring manual intervention. These variables self-configure to represent the calibration signals, enabling users to immediately perform reading and writing operations. The automated variable management system handles the complexity of variable creation and maintenance, freeing users from manual setup tasks.
