Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the charging station provides only basic charging service, then the device complexity is low, but the information completeness for travel planning is insufficient
Solution Approach 1:
The patent combines multiple functions into the charging station: basic charging service, travel route search, charging time calculation, and information provision. The processing circuitry integrates route search based on charge level recovery and provides comprehensive travel planning information, merging what would traditionally be separate systems into one unified device.
Solution Approach 2:
The charging station is designed with multi-functionality, serving not only as a charging device but also as a travel planning assistant. It can search for routes, calculate charging times, provide charge level recovery information, and display travel-related information, making it a universal device for both charging and navigation purposes.
2Measurement precision
If the system calculates detailed charge information for multiple charging stations, then the accuracy of travel planning information is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary calculations by determining charge level recovery and charging times in advance for multiple charging stations along the route. The processing circuitry calculates this information before the user makes a decision, allowing for accurate travel planning without real-time delays when the user needs the information.
Solution Approach 2:
The system calculates charge information for multiple charging stations (excessive action) rather than just one, providing the user with comprehensive options. This allows the user to see various charging scenarios and make informed decisions, with the understanding that not all calculated options will be used, but the comprehensive calculation enables better planning.
3Ease of operation
If the charging station provides comprehensive travel information, then the ease of operation for travel planning is improved, but the quantity of information processed increases
Solution Approach 1:
The information provided by the charging station is segmented into distinct, organized components: charge level recovery information, charging time calculations, route details, and station locations. The display device presents this segmented information in a structured manner, making the large quantity of information easier to process and understand for the user.
Solution Approach 2:
The processing circuitry acts as an intermediary that organizes and structures the comprehensive travel information before presenting it to the user. It calculates and arranges charge level recovery, charging times, and route information in a coherent format, mediating between the complex data processing and the user's need for clear, actionable information.
