Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex calculations are used to determine optimal parking paths, then parking precision is improved, but device complexity increases
Solution Approach 1:
The parking path calculation is segmented into three separate extended straight lines (first, second, and intermediate) instead of calculating one complex curved path. Each line represents a specific segment of the parking maneuver, simplifying the overall calculation while maintaining precision
Solution Approach 2:
The patent transforms the two-dimensional curved parking path problem into a series of one-dimensional straight line calculations by using extended straight lines. This dimensional simplification reduces computational complexity while achieving the same parking precision
2Ease of operation
If manual intervention is required for parking operations, then ease of operation is reduced, but reliability improves
Solution Approach 1:
The system performs preliminary detection of parking areas and pre-calculates the three extended straight lines before the actual parking maneuver. This preliminary action allows the vehicle to execute the parking automatically without manual intervention during the critical parking phase
Solution Approach 2:
The sensor device continuously provides feedback during the parking maneuver to verify the vehicle is following the calculated path correctly, allowing the system to maintain reliability while operating in automatic mode without manual intervention
3Ease of operation
If remote parking control is added, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The existing sensor device and controller are made multi-functional by adding remote detection capability. The same sensor device detects both local parking areas and remote smart key position, while the controller handles both automatic parking control and remote activation, eliminating the need for separate dedicated components

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.
