Automobile Theft Prevention System with Integrated Restraint Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-theft devices for motor vehicles are not sufficiently effective when used alone, as they do not comprehensively capture evidence of theft, restrict vehicle mobility, and restrain perpetrators, leading to high theft rates and property losses.
Innovation Solution
A security monitoring, theft prevention, and recovery system for automobiles that includes a control system with a microprocessor, transceiver, and intrusion sensor, featuring exterior and interior cameras, an automatic release air valve, and an automatic seatbelt immobilizing lock, which activate upon detection of invasive activity to capture video footage, restrict vehicle mobility, and restrain the perpetrator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single anti-theft device is used, then device complexity is reduced, but theft prevention effectiveness is insufficient
Solution Approach 1:
The patent combines multiple anti-theft functions (video surveillance, audio recording, GPS tracking, alarm, and physical restraint mechanisms) into a single integrated control system that responds to intrusion detection, thereby achieving comprehensive theft prevention while managing system complexity through unified control
2Loss of information
If video cameras are activated to capture footage, then evidence collection capability is improved, but energy consumption increases
Solution Approach 1:
The video and audio recording functions are activated periodically only when intrusion is detected, rather than operating continuously, thereby capturing necessary evidence while significantly reducing overall energy consumption of the system
Solution Approach 2:
The system pre-positions cameras and sensors to be ready for immediate activation upon detecting intrusion, allowing evidence capture to begin instantly without continuous operation, thus balancing evidence collection readiness with energy conservation
3Object-affected harmful factors
If air valve is activated to release pressure, then vehicle mobility restriction is improved, but control precision requirements increase
Solution Approach 1:
The air valve system is designed to automatically release tire pressure upon intrusion detection without requiring precise manual control, using the vehicle's existing air valve infrastructure to achieve mobility restriction through a simple binary state (pressurized or released) rather than nuanced control
4Object-affected harmful factors
If seatbelt latch is engaged to immobilize, then perpetrator restraint effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent uses the existing seatbelt latch mechanism as an intermediary component to achieve perpetrator restraint, leveraging the vehicle's built-in safety system rather than introducing a completely new restraint device, thereby achieving effective immobilization while minimizing additional system complexity

AI summary
A security monitoring, theft (and vandalism) prevention, and recovery system for automobiles includes an exterior light housing camera, an interior passenger cabin camera bar with an interior passenger cabin camera located within, an automatic release air valve located in a valve stem of an automobile wheel and tire assembly, and an automatic seatbelt immobilizing lock located in a seatbelt latch of an automobile. Upon detection of an invasive activity, an intrusion sensor provides an activation signal to a microprocessor. The exterior light housing camera and the interior passenger cabin camera are activated by the microprocessor to provide a video signal to the microprocessor via an activation signal. The quick release air valve and the seatbelt immobilizing lock are activated by the microprocessor to release air pressure from the wheel and tire and immobilize the seatbelt latch, respectively.
