Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image capturing devices and display systems are added to improve peripheral vision, then driver situational awareness is improved, but device complexity increases
Solution Approach 1:
The system divides the vehicle's exterior monitoring into multiple image capturing devices positioned at different locations (front, rear, sides) to capture specific zones. Each device focuses on a particular area, and the processor segments and reassembles these views to create comprehensive pillarless display images, thereby improving situational awareness without requiring a single overly complex device
Solution Approach 2:
The processor acts as an intermediary that receives images from multiple capturing devices, processes them to remove pillar obstructions, and generates composite views. The display system then presents these processed images to the driver. This intermediary processing layer enables complex functionality while keeping individual components relatively simple
2Measurement precision
If multiple sensors and processing units are deployed to predict future locations and routes of objects, then collision prediction accuracy is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary tracking and prediction of object trajectories using sensor data before collisions actually occur. By continuously analyzing location, speed, and direction data to forecast future positions and routes of pedestrians, vehicles, and other objects, the system prepares collision warnings in advance, improving prediction accuracy while distributing processing demands over time
Solution Approach 2:
The system uses feedback from multiple sensors (cameras, LIDAR, radar) to continuously update object tracking and prediction models. The processor compares predicted trajectories with actual object positions, refines predictions based on deviations, and adjusts collision risk assessments accordingly. This feedback loop improves measurement precision through iterative refinement
3Loss of time
If real-time processing of images and sensor data is implemented, then reaction time is improved, but use of energy increases
Solution Approach 1:
The system implements periodic processing cycles where images and sensor data are captured, processed, and displayed at regular intervals optimized for the specific application. Rather than continuous processing, the system updates pillarless views and collision predictions at frame rates sufficient for safety (e.g., 30-60 Hz), reducing energy consumption while maintaining adequate reaction time for driver response
Solution Approach 2:
The system performs preliminary processing of sensor data to identify and track objects of interest before full image processing is required. By pre-detecting pedestrians, vehicles, and obstacles using simpler sensor data analysis, the system can prioritize and accelerate processing only for relevant areas, reducing overall energy consumption while maintaining fast reaction times
4Reliability
If pillarless images are displayed to eliminate A-pillar obstructions, then peripheral vision is improved, but ease of operation decreases due to information overload
Solution Approach 1:
The display system applies local quality enhancement by selectively processing and displaying different regions of the pillarless images with appropriate emphasis. Critical areas such as detected pedestrians, vehicles, or obstacles are highlighted or enhanced in the composite views, while less critical areas are displayed with standard quality. This allows the driver to quickly identify important information without being overwhelmed by uniform high-detail displays of all areas
Solution Approach 2:
The system uses color changes and visual differentiation in the displayed pillarless images to convey important information. Detected objects are highlighted with specific colors or color overlays (e.g., red for high-risk obstacles, yellow for moderate risks), and trajectory predictions may be displayed with color-coded confidence levels. This visual coding helps drivers quickly interpret complex multi-source information without cognitive overload
