Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power exchange between power system, vehicle energy storage apparatus, and power load is implemented, then energy management capability is improved, but ease of grasping power exchange status deteriorates
Solution Approach 1:
A display device is introduced as an intermediary between the complex power exchange system and the user. The display device receives information from the control device and presents it in an intuitive visual format, mediating the complexity of multi-directional power flows between the power system, vehicle energy storage apparatus, and power load, thereby improving ease of grasping power exchange status while maintaining full energy management capability
2Measurement precision
If detailed power information is monitored and processed, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system is segmented into distinct functional modules: a control device that performs detailed power information monitoring and processing, and a display device that presents the processed information. This segmentation allows the control device to maintain high measurement precision for power information while the display device handles the complexity of information presentation, thereby reducing overall device complexity through functional separation
Solution Approach 2:
The display device acts as an intermediary that receives detailed power information from the control device and transforms it into simplified visual representations. This intermediary layer maintains measurement precision by faithfully transmitting accurate power information while reducing perceived complexity by presenting it in an intuitive format with direction diagrams and status indicators
