Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate non-isolated power converters are used for each component on the MCB, then each component receives dedicated power regulation, but the MCB occupies more space and has reduced power density
Solution Approach 1:
Multiple power converter functions are merged into a single integrated power converter that can serve multiple components. The power converter includes multiple output channels that can be independently controlled to provide different voltage levels to different components, eliminating the need for separate converters for each component while maintaining dedicated power regulation.
Solution Approach 2:
The power converter is designed with multi-functionality to serve multiple purposes. It can provide different voltage levels to different components simultaneously, and the output channels can be independently enabled or disabled based on which components are present on the MCB. This universal design allows one power converter to replace multiple dedicated converters.
2Adaptability or versatility
If isolated power converters are used to provide flexible power capacity, then power requirements can be adjusted, but the MCB power density is significantly reduced
Solution Approach 1:
The power converter incorporates dynamic control capabilities where output channels can be independently enabled or disabled based on the presence and power requirements of components. The controller can dynamically adjust which output channels are active, allowing flexible power capacity adaptation without requiring multiple physical converters or isolated power stages.
Solution Approach 2:
The power converter allows parameter changes in output voltage levels and output channel activation states. By changing which output channels are enabled and at what voltage levels they operate, the system can adapt to different power requirements without physical reconfiguration or additional hardware, maintaining high power density while providing versatility.
3Reliability
If multiple power converters are added to meet varied power requirements, then each component receives appropriate power, but the system cost increases
Solution Approach 1:
Multiple power converter functions are merged into a single integrated unit that provides multiple output channels. This consolidation reduces the total number of separate power converter components needed, lowering system cost while maintaining the ability to provide appropriate power delivery to each component through independent output channel control.
