Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple travel path options are analyzed using sensors (camera, radar, lidar), then the reliability of path selection is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensor types (camera, radar, lidar) into a unified travel path analysis system. The control system integrates data from all sensors to determine multiple travel path options and analyze their vertical dimensions, achieving reliable path selection through synergistic use of multiple sensing modalities rather than relying on a single sensor type.
Solution Approach 2:
The control system performs multiple functions using the same sensor data: it determines travel path options, analyzes vertical dimensions, identifies obstacles, and provides recommendations. This multi-functional approach improves reliability by utilizing comprehensive data from the sensor system for multiple analytical purposes without requiring separate dedicated systems for each function.
2Reliability
If travel paths are analyzed in detail considering vertical dimensions and obstacles, then the safety and reliability of vehicle operation is improved, but the processing time and computational complexity increase
Solution Approach 1:
The system performs preliminary analysis of vertical dimensions and obstacles along potential travel paths before the vehicle actually traverses them. By pre-calculating the vertical profiles and identifying clearance issues in advance, the system can provide timely recommendations to the driver without requiring real-time computational intensive analysis during vehicle operation.
Solution Approach 2:
The patent segments the travel path analysis into discrete components: determining multiple path options, analyzing vertical dimensions for each path, identifying obstacles, and generating recommendations. This segmentation allows the complex analysis to be broken down into manageable steps that can be processed efficiently and presented to the driver in a structured manner.
3Ease of operation
If a recommended travel path is provided based on vertical dimension analysis, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The control system provides feedback to the driver by analyzing the vertical dimensions of travel paths and presenting recommended paths with their associated characteristics. This feedback mechanism simplifies the driver's decision-making process by providing expert analysis and recommendations based on the analyzed vertical profiles and obstacle information, making the complex analysis transparent and actionable.
