Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual methods are used for reading and writing calibration signals (opening database, selecting signals, dragging to windows, manual modification), then the system maintains simplicity in implementation, but the operation efficiency is low and the process is time-consuming
Solution Approach 1:
The system enables self-service automation where calibration signals are automatically read, mapped to system variables, and processed without manual intervention. The mapping relationship between calibration signals and system variables is established automatically, allowing the system to serve itself in terms of data acquisition and variable assignment, thereby improving productivity while maintaining implementation simplicity
Solution Approach 2:
The mapping system variable mechanism provides universal functionality that handles both reading and writing operations for multiple calibration signals through a unified interface. This multi-functional approach allows the same system variable structure to serve multiple purposes (observation, calibration, mathematical operations), improving efficiency without significantly increasing system complexity
2Loss of time
If manual dragging and dropping of signals to monitoring windows is used, then the interface operation is straightforward, but the time required for signal observation and modification is excessive
Solution Approach 1:
The system performs preliminary actions by pre-establishing mapping relationships between calibration signals and system variables before actual observation or modification is needed. This advance preparation includes automatically creating variable mappings and assigning initial values, so that when signals need to be observed or modified, the system is already ready, significantly reducing the time required for these operations
Solution Approach 2:
The mapping system variable acts as an intermediary between the calibration database and the monitoring/modification interface. Instead of directly manipulating calibration signals through complex database operations, users interact with simplified system variables that automatically handle the intermediate processing, reducing both time and operational complexity
3Adaptability or versatility
If calibration signals are to be used for mathematical operations or custom variable modifications, then the system gains enhanced functionality, but the programming complexity increases significantly
Solution Approach 1:
The system creates copies of calibration signal data in the form of mapping system variables that can be freely used for mathematical operations and custom variable modifications. These variable copies contain the same data as the original calibration signals but can be manipulated without affecting the source data, enabling enhanced functionality while keeping programming simple through familiar variable operations
Solution Approach 2:
The system segments the calibration signal handling into distinct functional components: the original calibration database, the mapping relationship layer, and the system variable layer for operations. This segmentation allows mathematical operations and custom modifications to be performed on the variable layer without complicating the underlying calibration system, maintaining programming simplicity while enhancing adaptability
