Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a system is designed for specific components and devices, then the system configuration is simplified and optimized, but the system cannot test alternative components or devices
Solution Approach 1:
The system is divided into modular components: a mother board and multiple interchangeable daughter boards. Each daughter board is designed with standardized connection interfaces that allow them to be easily swapped on the mother board. This segmentation enables the system to test different active devices by simply changing the daughter board, without redesigning the entire system.
Solution Approach 2:
The mother board is designed with universal connection interfaces and control circuitry that can work with multiple types of daughter boards. The measurement circuitry on the mother board is configured to automatically adapt to different active devices through standardized protocols, allowing one system to serve multiple testing purposes without requiring separate dedicated systems for each device type.
2Adaptability or versatility
If multiple dedicated evaluation systems are designed for different components, then each system is optimized for its specific component, but the overall system count and cost increase
Solution Approach 1:
A single mother board platform is designed to support multiple daughter boards for different active devices (power devices, gate driver circuits, etc.). The mother board includes universal measurement circuitry and control logic that can automatically configure itself based on which daughter board is connected, enabling one system to replace multiple dedicated systems and improving manufacturing efficiency through standardization.
Solution Approach 2:
The system uses configurable parameters and software settings that can be adjusted based on the installed daughter board type. The measurement circuitry parameters, sampling rates, and test protocols can be dynamically changed to match the specific active device being tested, allowing the same hardware platform to efficiently evaluate multiple different components without physical redesign.
