Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional SVM systems are used for autonomous parking, then basic monitoring is provided, but the user experience is fragmented and lacks interaction
Solution Approach 1:
The patent combines SVM camera feed with ultrasonic sensor data into a unified augmented reality display. The graphic overlays integrate parking slot detection, motion path planning, and real-time sensor feedback into a single cohesive interface, eliminating the fragmented experience of separate monitoring systems while providing seamless autonomous parking guidance.
2Measurement precision
If basic SVM monitoring is used, then system simplicity is maintained, but detection accuracy of parking slots is unreliable
Solution Approach 1:
The patent uses graphic overlays as an intermediary layer that translates ultrasonic sensor data into visual representations on the SVM feed. This intermediary layer processes sensor signals to identify parking slots, mark boundaries, and display motion paths, thereby enhancing detection accuracy while maintaining a user-friendly interface that doesn't reveal the underlying system complexity.
3Adaptability or versatility
If static SVM display is used, then system simplicity is maintained, but user immersion and perspective flexibility are limited
Solution Approach 1:
The patent implements dynamic graphic overlays that adapt to user-selected perspectives and camera angles. The motion path graphics and parking slot markers automatically adjust their orientation and position based on the vehicle's movement and the user's chosen view, providing versatile perspective flexibility while the system handles the computational complexity of real-time display processing.
4Productivity
If manual parking control is used, then user control is maintained, but parking maneuver precision and efficiency are reduced
Solution Approach 1:
The patent implements real-time feedback through graphic overlays that show the vehicle's motion path, parking slot boundaries, and environmental obstacles. This visual feedback system guides the autonomous parking maneuver by continuously comparing actual vehicle position with the planned trajectory, enabling precise and efficient parking while the system manages the operational complexity of coordinating sensors, actuators, and real-time calculations.

AI summary
A method comprises: receiving a surround view monitoring (SVM) video feed from SVM cameras of a vehicle; identifying, using the SVM video feed and a signal from one or more ultrasonic sensors of the vehicle, a first parking slot that is available for parking the vehicle, the first parking slot associated with coordinates; overlaying, using the coordinates of the first parking slot, a first graphic on the SVM video feed to generate an augmented SVM video feed, the first graphic representing the first parking slot; and presenting the augmented SVM video feed including the graphic on a display device of the vehicle, wherein the first graphic is selectable by a user to trigger an autonomous parking maneuver of the vehicle into the first parking slot, and wherein the augmented SVM video feed facilitates freeform perspective change by the user.
