Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a converter arrangement is designed with extensive input and display options as well as specific data interfaces to meet various application requirements, then the functionality and adaptability are improved, but the production cost and device complexity increase
Solution Approach 1:
The converter arrangement is divided into two separate modules: a base module containing power electronics and control electronics, and a signal electronics module containing input means, display means, and data interfaces. This segmentation allows the base module to remain simple and cost-effective while the signal electronics module provides the necessary adaptability and functionality for different applications.
Solution Approach 2:
The base module is designed as a universal platform that can be combined with different signal electronics modules to meet various application requirements. The standardized interface between modules enables one base module to work with multiple types of signal electronics, providing multi-functionality without increasing the complexity of the base module itself.
2Adaptability or versatility
If a converter arrangement is designed with extensive input and display options as well as specific data interfaces to meet various application requirements, then the functionality and adaptability are improved, but the production cost increases
Solution Approach 1:
By separating the converter into a base module and a signal electronics module, the production cost is reduced because the base module can be manufactured in large quantities as a standardized component. The signal electronics module is only produced when needed for specific applications, avoiding the cost of incorporating all possible functionalities into every unit.
Solution Approach 2:
Different signal electronics modules with specific input, display, and interface capabilities are attached only to base modules where those specific functionalities are required. This ensures that each converter arrangement has the exact functionality needed for its application without paying for unnecessary features, optimizing production cost effectiveness.
3Measurement precision
If signal electronics with higher-level regulation capabilities are added to the converter arrangement, then the control precision and application-specific functionality are improved, but the control load and processing requirements increase
Solution Approach 1:
The control functions are segmented between the base module and the signal electronics module. The signal electronics module handles higher-level regulation and determination of manipulated variables, while the base module executes the actual control of power semiconductor switches. This segmentation allows precise control without overloading the base module's processor.
Solution Approach 2:
The signal electronics module acts as an intermediary between the application-specific requirements and the base module's control electronics. It processes application-specific signals and determines manipulated variables, then transmits them to the base module for execution, distributing the processing load appropriately.
