Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the driver operates the vehicle without power usage guidance, then the driving style is free and flexible, but the power usage efficiency deteriorates and range is reduced
Solution Approach 1:
The system provides real-time feedback to the driver by displaying required power usage and efficiency indications on the interface. The processing unit continuously monitors environmental parameters and vehicle operational data, compares actual power usage with required power usage, and provides guidance feedback to help the driver improve power usage efficiency without significantly increasing system complexity
Solution Approach 2:
The system enables the driver to self-adjust driving behavior based on the provided efficiency indications. Rather than automatically controlling the vehicle, the system serves the driver with information and guidance, allowing the driver to make informed decisions about power usage while maintaining driving freedom and flexibility
2Use of energy by moving object
If the vehicle operates without environmental parameter consideration, then the system operation is simple, but the power usage efficiency deteriorates under varying environmental conditions
Solution Approach 1:
The processing unit estimates the required power usage in advance by considering environmental parameters (temperature, humidity, road conditions) and vehicle operational data before the driver actually operates the vehicle. This preliminary estimation allows the system to provide accurate power usage guidance tailored to current environmental conditions, improving power efficiency without requiring complex real-time adjustments
Solution Approach 2:
The system dynamically adapts to varying environmental conditions by continuously updating the required power usage estimation based on real-time environmental parameter changes. The interface updates efficiency indications dynamically to reflect current conditions, allowing the vehicle operation to be optimized for each specific environmental context
3Loss of information
If the system provides detailed power usage information, then the driver awareness of power consumption improves, but the information processing complexity increases
Solution Approach 1:
The system extracts and displays only the most critical power usage information to the driver through the interface - specifically the required power usage and efficiency indications. Rather than presenting all available data, the system selectively extracts the essential information needed for driver awareness, reducing processing complexity while maintaining effective communication of power consumption status
