Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional fuel prompt systems only display remaining fuel quantity, then the system complexity is low, but the information completeness deteriorates (cannot provide reachable range information)
Solution Approach 1:
The patent combines multiple information sources (fuel quantity sensor, GPS position information, pre-stored road section fuel consumption data) into a unified reachable range calculation system. The central processing unit integrates these diverse data types to compute both remaining fuel quantity and reachable range simultaneously, resolving the contradiction by merging measurement, location, and calculation functions into a cohesive system.
Solution Approach 2:
The fuel prompt system is transformed into a multi-functional device that not only displays remaining fuel quantity but also calculates reachable range, identifies road sections, and provides navigation guidance to gas stations. The central processing unit serves multiple purposes: storing road data, calculating fuel consumption, determining position, and generating prompts, thereby improving information completeness without proportionally increasing complexity.
2Measurement precision
If the system calculates reachable range using real-time fuel consumption data, then the measurement precision improves, but the loss of time increases (data collection and calculation time)
Solution Approach 1:
The patent pre-stores road section fuel consumption data and vehicle information in the central processing unit before actual navigation needs arise. By having this reference data readily available, the system eliminates the need for real-time complex calculations during navigation, thus improving measurement precision while minimizing time loss. The preliminary storage of calibration data allows for rapid comparison and calculation during actual use.
3Reliability
If the system provides comprehensive reachable range and gas station information, then the reliability of fuel management improves, but the device complexity increases (additional modules required)
Solution Approach 1:
The system automatically performs fuel consumption calculation, position determination, and reachable range computation without requiring user intervention. The central processing unit self-manages the integration of sensor data, GPS information, and stored road data to generate accurate reachable range information and gas station recommendations, thereby improving reliability while keeping the user interface simple and the operational complexity low.
