Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only short-range sensors are used for parking detection, then the system is simple and cost-effective, but the detection range is limited and long-distance parking spaces cannot be detected
Solution Approach 1:
The sensor system is segmented into two distinct components: a short-range sensor (first sensor) for detecting nearby obstacles and parking lines, and a long-range sensor (second sensor) for detecting distant parking spaces. This segmentation allows each sensor to be optimized for its specific detection range, resolving the contradiction between detection range and system complexity by dividing the detection task into manageable segments rather than using a single complex sensor system
Solution Approach 2:
The patent merges the functionality of short-range and long-range sensors into a unified parking assistance system. The processor integrates detection results from both sensors to comprehensively identify parking spaces at various distances. This merging allows the system to achieve extended detection range while maintaining manageable complexity through coordinated operation of complementary sensor components
2Adaptability or versatility
If traditional parking assistance systems are used, then the system structure is simple, but the ability to detect three-dimensional obstacles and recognize environmental features is insufficient
Solution Approach 1:
The sensor system is designed with multi-functionality to perform diverse detection tasks: the short-range sensor detects both obstacles and parking lines, while the long-range sensor detects parking spaces and environmental features. The processor universally processes various types of detection data to identify different environmental elements. This universality enables comprehensive environmental recognition without requiring separate specialized systems for each function, resolving the contradiction between versatility and complexity
Solution Approach 2:
The system transitions from two-dimensional image-based detection to three-dimensional spatial understanding by integrating depth information from both sensors. The long-range sensor provides distance measurements that add a third dimension to the environmental model, enabling the system to recognize three-dimensional obstacles and understand spatial relationships. This dimensional enhancement improves environmental feature recognition while maintaining system manageability through coordinated sensor operation
3Productivity
If manual parking operation is used, then the system is simple and does not require complex automation, but the parking process requires driver intervention and is less efficient
Solution Approach 1:
The system performs preliminary detection and analysis of the parking environment before the actual parking maneuver. The sensors continuously scan and identify suitable parking spaces, obstacles, and environmental features in advance. The processor pre-calculates parking trajectories and plans based on detected information. This preliminary action enables more efficient automatic parking execution by preparing all necessary information and plans before the vehicle begins moving into the parking space, resolving the contradiction between productivity and automation extent
