Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a vehicle checks detailed information on charging stations to determine service availability, then the accuracy of state information is improved, but the time and efforts required for checking increase
Solution Approach 1:
The system performs preliminary actions by proactively searching for and verifying charging station status information before the vehicle reaches the destination. The navigation device automatically queries charging station availability, compatibility, and operational status, and pre-arranges charging stops without requiring manual user verification during travel.
Solution Approach 2:
The navigation device performs self-service by automatically gathering, analyzing, and evaluating charging station information without user intervention. The system autonomously determines charging compatibility, checks service availability, calculates optimal charging stops, and manages the entire charging planning process independently of manual user input.
2Productivity
If a vehicle encounters charging stations during driving without advance planning, then the immediate charging opportunity is utilized, but the vehicle may waste time searching for functional stations when battery power is insufficient
Solution Approach 1:
The system performs preliminary routing that proactively identifies and incorporates functional charging stations into the navigation path before battery depletion occurs. By verifying charging station status in advance and pre-planning charging stops, the system ensures continuous charging availability without requiring reactive searching when the vehicle runs low on power.
3Measurement precision
If the navigation device manually adds charging stations to the route, then the charging station location is accurately set, but the user operation complexity increases
Solution Approach 1:
The navigation device performs self-service by automatically identifying, verifying, and incorporating charging stations into the route without user intervention. The system autonomously queries charging station data, evaluates compatibility and availability, determines optimal charging stop locations, and seamlessly integrates these into the navigation path, eliminating manual user operations entirely.
4Reliability
If the system provides comprehensive charging station information, then the charging success probability increases, but the information processing complexity increases
Solution Approach 1:
The system extracts and prioritizes only the essential charging station parameters needed for successful charging, such as operational status, compatibility, and availability. By filtering out redundant information and focusing on critical data points, the system maintains high charging success probability while minimizing information processing complexity and computational burden.
