Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power sensors and communication interfaces are added to enable active power value provision, then the capability to track carbon footprint is improved, but the device complexity increases
Solution Approach 1:
The processor performs multiple functions: collecting power sensing signals from power sensors, generating power values, and providing them to the host through communication interfaces. This multi-functionality reduces the need for separate dedicated circuits, thereby managing device complexity while enabling carbon footprint tracking capability.
Solution Approach 2:
The power sensing signals serve as an intermediary that bridges the functional circuits and the host system. By using standardized power sensing signals and communication protocols, the system enables carbon footprint tracking without requiring complex direct integration between all components.
2Measurement precision
If multiple power sensors are deployed to sense power of functional circuits, then the measurement precision of power consumption is improved, but the device complexity increases
Solution Approach 1:
The system divides the power measurement function into separate modular components: power sensors for sensing, processor for calculation, and communication interfaces for data transmission. This segmentation allows precise power measurement of individual functional circuits while maintaining manageable system complexity through modular architecture.
