Innovation Solution
A vehicle security device equipped with a sensor that detects obstacles and moves them to prevent interference with peripheral monitoring, ensuring accurate detection of suspicious objects by using a notification unit, obstacle detection unit, and obstacle movement unit, integrated with a cloud communication system and actuator-controlled equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor is arranged in the vehicle compartment to monitor the periphery, then the detection capability is improved, but obstacles such as seats and monitors create blind spots that reduce detection accuracy
Solution Approach 1:
The system performs preliminary detection of obstacles (seats, monitors) in the vehicle compartment before initiating periphery monitoring. By identifying and accounting for these obstacles in advance, the system can adjust its monitoring strategy to avoid blind spots created by these objects, thereby maintaining high detection accuracy.
Solution Approach 2:
The monitoring system dynamically adjusts its operation based on the presence of obstacles. When obstacles are detected in the vehicle compartment, the system modifies its monitoring pattern to account for the created blind spots, transitioning from a static monitoring approach to a dynamic one that adapts to the environmental conditions.
2Reliability
If the sensor continuously monitors the periphery, then the security coverage is improved, but power consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system employs periodic monitoring cycles. The sensor alternates between active monitoring phases and standby phases, reducing overall power consumption while maintaining adequate security coverage. This periodic operation is particularly effective when combined with obstacle detection, where monitoring intensity can be adjusted based on the presence of obstacles.
Solution Approach 2:
The system uses the obstacle detection function to intelligently control the monitoring operation. When no obstacles are present, the system can operate with higher monitoring intensity. When obstacles create blind spots, the system automatically adjusts its monitoring strategy, allowing it to serve itself by making autonomous decisions about resource allocation based on environmental conditions.
3Measurement precision
If obstacles are moved to eliminate blind spots, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
Instead of using complex mechanical systems to physically move obstacles, the patent employs electromagnetic fields generated by the sensor to detect and account for obstacle positions. The system substitutes mechanical obstacle relocation with electromagnetic field-based detection and computational adjustment of monitoring patterns, significantly reducing device complexity while maintaining detection accuracy.
4Measurement precision
If obstacle detection is performed before periphery monitoring, then monitoring accuracy is improved, but the process time increases
Solution Approach 1:
The system merges the obstacle detection function with the periphery monitoring function into a unified sensor system. By using the same sensor for both obstacle detection and periphery monitoring, the patent eliminates the need for separate detection phases, allowing obstacle identification and periphery monitoring to occur in an integrated manner that minimizes additional process time while maintaining high monitoring accuracy.

AI summary
A sensor detects a target by transmitting and receiving an electromagnetic wave, and is arranged in a vehicle compartment. A user's mobile terminal is notified via a cloud system when a vehicle is parked, and a suspicious object around the vehicle is detected by monitoring a periphery of the vehicle using the sensor. An obstacle interfering with a periphery monitoring and disposed in the vehicle compartment is detected using the sensor prior to the periphery monitoring. A detected obstacle is moved so as not to interfere with the periphery monitoring.
