Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional automatic parking systems use complex calculations to derive moving paths, then parking accuracy is improved, but system complexity increases
Solution Approach 1:
The moving path is divided into multiple straight line segments (first extended straight line, second extended straight line, intermediate extended straight line) instead of using complex curved path calculations. Each segment connects key points (vehicle position, parking area boundaries) to create a simplified yet accurate parking trajectory that avoids obstacles while maintaining precision.
Solution Approach 2:
An intermediate extended straight line is introduced as a mediator to connect the first and second extended straight lines. This intermediate line serves as a transition path that allows the vehicle to smoothly change direction while avoiding direct complex angular calculations, thereby simplifying the overall path derivation process.
2Area of stationary object
If the parking area length is short, then parking space utilization is improved, but path derivation complexity increases
Solution Approach 1:
The system dynamically adjusts the angle of the second extended straight line relative to the longitudinal direction of the parking area based on the actual length of the parking area. When the parking area is short, the angle is optimized to accommodate the limited space, creating an adaptive path that simplifies calculations while maximizing space utilization.
3Device complexity
If manual parking operation is used, then system simplicity is maintained, but parking difficulty for inexperienced drivers persists
Solution Approach 1:
The automatic parking system enables the vehicle to perform parking maneuvers autonomously by automatically controlling steering, acceleration, and braking based on the calculated extended straight line paths. The system detects parking areas and obstacles independently, then executes the parking sequence without requiring driver intervention, making parking accessible to inexperienced drivers while keeping the overall system concept simple.
4Ease of operation
If remote parking control via smart key is added, then parking convenience is improved, but device complexity increases
Solution Approach 1:
The smart key is given multi-functionality by integrating both traditional vehicle access/start functions and remote parking control capabilities. The same smart key device communicates with the vehicle's automatic parking system to initiate and control the parking sequence remotely, eliminating the need for separate control devices and minimizing additional complexity while maximizing convenience.

AI summary
An automatic parking system includes a smart key recognizing sensor recognizing a smart key positioned in a first area, a sensor device detecting parking areas depending on a size of a subject vehicle if the smart key is recognized and a controller controlling the subject vehicle to be parked in an optimal parking area among the parking areas, in which the sensor device may detect the parking area in consideration of a length and a width of the subject vehicle and the controller may calculate a moving path between a current position of the subject vehicle and the optimal parking area.
