Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated parking systems rely on driver behavior and can be compromised by hacking or inadequate sensor detection, leading to safety concerns during parking maneuvers.
Innovation Solution
A method and system that utilize proximity sensors and an authorized user as an additional sensor to verify the safety of the maneuver zone, ensuring only authorized individuals initiate and monitor parking maneuvers, using a combination of ultrasound, IR, or laser sensors for 360° detection and RF communication for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver uses a handheld device to send keep-alive signals and press buttons on remote control, then the vehicle can perform parking maneuvers with intentional driver action, but the system remains vulnerable to hacking and the driver may not actually monitor the vehicle
Solution Approach 1:
The patent introduces an intermediary authentication mechanism where the system verifies that the authorized user is physically present in the maneuver zone before allowing the parking maneuver to proceed. This intermediary check (detecting the user's presence and monitoring their movement) bridges the gap between simple remote control and complex continuous monitoring, providing enhanced safety without requiring the driver to constantly interact with the device.
Solution Approach 2:
The system implements feedback by continuously monitoring the maneuver zone for objects and verifying that the authorized user moves out of the zone before execution. This feedback loop provides real-time information about the safety of the maneuver, allowing the system to proceed only when conditions are verified to be safe, thereby enhancing reliability without requiring complex continuous driver intervention.
2Reliability
If proximity sensors are used to detect objects in the vicinity, then the vehicle can identify potential obstacles, but sensors may fail to detect all objects under all circumstances
Solution Approach 1:
The patent combines multiple detection approaches: proximity sensors for detecting objects in the maneuver zone, and authentication mechanisms to identify the authorized user. By merging these detection systems and cross-verifying their outputs, the system achieves more reliable detection than either system could provide alone, without requiring an excessively complex sensor array.
Solution Approach 2:
The system uses the authorized user themselves as part of the detection mechanism. By requiring the user to be present in the maneuver zone and then verifying they move out, the system effectively uses the user's presence and movement as an additional detection layer, compensating for limitations in automated sensor detection without adding complex external monitoring systems.
3Reliability
If the system requires continuous driver interaction, then hacking risks are reduced, but the driver may adopt convenient behaviors that compromise safety
Solution Approach 1:
The patent performs preliminary authentication and safety verification actions before the parking maneuver is executed. The system detects the authorized user in the maneuver zone, verifies their presence, and confirms they will move out before allowing the maneuver to proceed. This preliminary action sequence provides security against hacking while maintaining ease of operation, as the driver only needs to initiate the sequence rather than continuously interact.
Solution Approach 2:
The system enables the authorized user to serve multiple functions: initiating the maneuver, being detected as present in the zone (providing authentication), and moving out to clear the zone (providing safety verification). This self-service approach enhances security without requiring continuous external interaction, as the user's own actions provide the verification needed for safe execution.
