Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional navigation information is provided through conventional displays, then the device complexity is low, but the measurement precision of lane information and reliability of collision prevention are insufficient
Solution Approach 1:
The patent introduces an intermediary system that receives lane information from multiple sources (sensors, maps, other vehicles) and processes it into augmented reality visualizations. This intermediary layer enhances measurement precision by integrating and validating data from various inputs while managing system complexity through modular architecture.
Solution Approach 2:
The patent transitions from two-dimensional conventional displays to three-dimensional augmented reality overlays that project lane information directly onto the driver's field of view. This dimensional change provides more intuitive and precise lane guidance while maintaining manageable complexity through software-based rendering.
2Reliability
If real-time data from multiple vehicles is received and processed, then the reliability of collision prevention improves, but the loss of time for data processing increases
Solution Approach 1:
The system performs preliminary processing of vehicle data by pre-establishing communication channels and pre-processing incoming data streams. Lane information from other vehicles is pre-formatted and validated before reception, reducing the time required for real-time processing while maintaining high reliability in collision prevention.
Solution Approach 2:
The patent implements prioritized processing that skips non-critical data validation steps when collision risk is detected. Critical lane information is processed and displayed immediately without waiting for complete data verification, reducing processing time while maintaining sufficient reliability through post-processing validation.
3Ease of operation
If augmented reality carpet images are displayed to show lane information, then the ease of operation for lane change guidance improves, but the illumination intensity requirements increase
Solution Approach 1:
The patent uses color-coded carpet images with high-contrast patterns that provide intuitive lane guidance through color differentiation rather than relying solely on brightness. Different colors indicate different lane states and guidance priorities, improving ease of operation while reducing the overall illumination intensity required for effective display.
