Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the processing unit transmits actual road conditions directly to the instrument for display, then the display shows real-time road conditions, but the display accuracy and user experience deteriorate due to inaccurate vehicle positions and disproportionated sizes
Solution Approach 1:
The patent introduces an intermediary processing layer between the sensor unit and instrument that calculates relative positions and determines display parameters. This intermediary processing ensures display accuracy while maintaining real-time capability by efficiently computing position relationships before transmission to the display.
Solution Approach 2:
The system transforms raw sensor data into optimized display parameters by calculating relative positions, determining vehicle models based on distance, and adjusting display attributes. This parameter transformation resolves the contradiction by presenting accurate, appropriately-scaled vehicle representations in real-time.
2Loss of information
If the instrument displays all preceding vehicles with accurate positions, then the completeness of information is improved, but the device complexity increases due to computational requirements
Solution Approach 1:
The patent applies different display qualities to different vehicles based on their relative positions and relevance. Nearby vehicles receive more detailed processing and larger display models, while distant vehicles use simplified representations. This local differentiation maintains information completeness while reducing overall computational complexity.
Solution Approach 2:
The display system segments vehicles into different categories (nearby, distant, same lane, adjacent lanes) and processes each segment with appropriate computational resources. This segmentation allows the system to maintain complete information while optimizing computational efficiency by applying different processing levels to different vehicle groups.
3Illumination intensity
If the instrument displays larger vehicle models for distant vehicles, then the visibility is improved, but the accuracy of distance representation deteriorates
Solution Approach 1:
The system dynamically adjusts vehicle model sizes based on calculated distance relationships. Vehicles closer to the ego vehicle are displayed with smaller models to maintain accurate spatial representation, while distant vehicles receive larger models for improved visibility. This dynamic adjustment resolves the contradiction by adapting display parameters to each vehicle's specific distance.
