Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control methods are used for analog devices, then the device complexity remains low, but the ease of operation deteriorates due to the need for memory and manual re-adjustment
Solution Approach 1:
A digital control module is introduced as an intermediary between the user and the analog device. This module receives digital control signals, stores parameter settings in non-volatile memory, and automatically adjusts analog control elements, eliminating the need for manual memory and re-adjustment while maintaining analog signal processing
Solution Approach 2:
Manual mechanical adjustment of analog control elements is replaced with digital control signals. The digital control module communicates with the analog device through electrical/digital interfaces, substituting the mechanical turning of knobs and switches with electronic control while preserving the analog processing path
2Productivity
If manual parameter changes are made over time, then the adaptability is maintained, but the loss of time increases due to dedicated personnel requirements
Solution Approach 1:
The analog device is equipped with automatic parameter adjustment capability through digital control. The system can automatically recall stored settings and adjust parameters without requiring dedicated personnel, enabling self-service operation and significantly reducing time loss
Solution Approach 2:
Parameter settings are pre-stored in non-volatile memory for different time points or scenarios. When needed, the system automatically retrieves and applies these pre-stored settings, eliminating the need for manual re-adjustment and dedicated personnel intervention
3Ease of operation
If digital control is implemented in analog devices, then the ease of operation improves through automated control, but the device complexity increases due to additional control modules
Solution Approach 1:
The control system is segmented into separate functional modules: a digital control module for receiving and processing control signals, a non-volatile memory module for storing parameters, and the existing analog processing module. This modular approach manages complexity by separating functions while maintaining ease of operation
4Loss of information
If manual memory is relied upon for parameter settings, then the device complexity remains low, but the loss of information increases due to inability to store and recall settings
Solution Approach 1:
Parameter settings are digitally copied and stored in non-volatile memory within the analog device. This digital copy preserves the exact parameter values without degradation, allowing perfect recall and elimination of information loss associated with manual memory, while adding only minimal storage complexity
