Engineering Contradiction Analysis
1Productivity
If traditional manual reading and writing methods of calibration signals are used, then operators can access calibration databases and modify signal values, but the process requires complex drag-and-drop operations, manual value filling, and multiple confirmation steps, significantly reducing operational efficiency
Solution Approach 1:
The patent introduces mapping system variables as an intermediary layer between calibration signals and the calibration database. These mapping variables serve as a bridge that simplifies access to calibration signals, allowing operators to read and write values through simple variable assignments rather than complex database operations. The mapping variables translate high-level operational requests into precise database operations automatically.
Solution Approach 2:
The patent creates mapping system variables that are copies or representations of the actual calibration signals. Instead of directly manipulating calibration signals through complex procedures, operators work with these simplified mapping variables that mirror the signal values. This copying mechanism allows efficient reading and writing operations while maintaining synchronization with the original calibration database through automatic updates.
2Adaptability or versatility
If calibration signals are directly accessed through the calibration database, then signal values can be modified, but mathematical operations and custom variable manipulations cannot be performed efficiently without complex API calls and protocol matching
Solution Approach 1:
The mapping system variables are designed to be self-service entities that automatically handle the complexity of database interactions. When operators perform mathematical operations or manipulations on mapping variables, the system automatically translates these operations into appropriate database operations without requiring operators to understand or implement complex API calls or protocol matching. The mapping variables serve themselves by maintaining automatic synchronization with the calibration database.
Solution Approach 2:
The mapping system variables serve multiple functions: they represent calibration signal values, enable mathematical operations, facilitate custom variable manipulations, and automatically synchronize with the calibration database. This multi-functionality allows operators to perform diverse operations on calibration signals through a unified, simplified interface rather than requiring different complex procedures for different operations.
