Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vehicle uses conventional parking assistance systems, then it can perform autonomous parking in perpendicular and parallel spaces, but it cannot determine or park in diagonal parking spaces
Solution Approach 1:
The parking assistance system is enhanced to perform multiple functions by adding diagonal parking space detection capability to the existing perpendicular and parallel parking detection functions. The object detection apparatus and processor are configured to identify different parking space types and generate appropriate parking paths for each type, making the system universal across various parking configurations without requiring separate dedicated systems
2Adaptability or versatility
If the parking assistance system adds diagonal parking detection capability, then it can identify and park in diagonal spaces, but the system complexity increases
Solution Approach 1:
The parking space detection process is segmented into distinct analytical steps: generating a reference line from detected parking spaces, calculating angles between side parking lines and the reference line, and classifying the parking space type based on angle thresholds. This segmentation breaks down the complex diagonal parking detection into manageable modules that can be processed sequentially by the existing processor architecture
Solution Approach 2:
The system introduces a new dimension of analysis by adding angle measurement to the existing parking space detection. Instead of only detecting the presence and position of parking spaces, the system now measures the angle between side parking lines and a reference line, adding angular information as an additional dimension that enables diagonal parking identification while utilizing the same sensor and processor infrastructure
3Manufacturing precision
If the system generates parking paths for diagonal spaces, then accurate diagonal parking is achieved, but the path generation process becomes more complex
Solution Approach 1:
The path generation algorithm adapts to different parking space types by changing key parameters such as the reference line orientation and angle thresholds. For diagonal parking spaces, the system modifies the angular parameters and path geometry parameters based on the detected angle between side parking lines and the reference line, allowing accurate path generation for diagonal spaces while reusing the same path generation framework used for perpendicular and parallel parking
