Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual selection operations are performed for parameter calculation, then data point selection can be made, but the operation process becomes tedious and calculation complexity increases
Solution Approach 1:
The system enables self-service by automatically selecting data points based on user-defined rules. The selection rule editor allows users to configure criteria once, and the system autonomously performs data point selection without requiring manual intervention for each calculation, thus improving ease of operation while maintaining accuracy
Solution Approach 2:
The invention applies preliminary action by pre-configuring selection rules before parameter calculation. Users define selection criteria in advance through the rule editor, and the system prepares data point selections based on these predefined rules, eliminating the need for repeated manual selections and reducing operational complexity
2Extent of automation
If complex interface settings are used for automatic selection, then data range selection can be automated, but the interface complexity increases
Solution Approach 1:
The invention extracts the essential selection logic from complex interface operations. By separating the core selection criteria from the overall system interface, the patent creates a focused rule editor that handles automation independently, reducing the burden on the main interface while maintaining high automation capability
Solution Approach 2:
The selection system is segmented into modular components: the selection rule editor, the rule execution engine, and the parameter calculation module. This segmentation allows automation to be implemented in a structured way, where each component has a specific function, reducing overall interface complexity while preserving automation benefits
3Manufacturing precision
If manual calculation of threshold voltage for each data point is performed, then precise data selection can be achieved, but calculation time and operational effort increase significantly
Solution Approach 1:
The invention replaces manual mechanical calculation operations with automated computational processes. The selection rule editor and execution engine automatically calculate threshold voltages and select data points based on predefined criteria, substituting manual arithmetic operations with algorithmic processing that maintains precision while dramatically improving efficiency
Solution Approach 2:
The system changes the parameter representation by using configurable selection rules that define data point criteria in terms of voltage offsets, thresholds, and ranges. This parameter-based approach allows precise data selection through automated rule evaluation rather than manual calculation, maintaining accuracy while reducing operational effort
