Vehicle Safety System With Delayed Alarms for Hijacking Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle hijacking poses a significant threat to owners, occupants, and law enforcement, as current security systems fail to adequately prevent or reduce the incidence of hijacking, leading to dangerous situations and challenges in identifying and apprehending perpetrators.
Innovation Solution
A safety system for vehicles that generates detectable signals and images after a time delay, making the vehicle a visible spectacle to deter hijackers and facilitate tracking, while allowing immediate electronic notification to law enforcement, thereby reducing the risk of violent reactions and enhancing recovery chances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If immediate alarm signals are generated upon detecting unauthorized possession, then the vehicle's visibility and trackability are improved, but the risk of violent reaction from the hijacker increases
Solution Approach 1:
The system performs preliminary actions by immediately transmitting electronic signals and generating images of the hijacker upon detecting unauthorized possession, while delaying the generation of loud audible alarm signals. This preliminary tracking action establishes vehicle location and perpetrator identification before potentially dangerous alarm signals are activated.
Solution Approach 2:
The alarm system is segmented into multiple independent signal generation modes: electronic signals for tracking, image capture for identification, and audible/visual alarm signals for deterrence. This segmentation allows selective activation of different signal types based on the situation, enabling the system to track and identify without immediately triggering violent confrontation.
2Object-affected harmful factors
If no immediate alarm is generated to avoid violent reaction, then the safety of occupants is improved, but the vehicle's visibility and trackability deteriorate
Solution Approach 1:
The system performs preliminary tracking and identification actions immediately upon detecting hijacking through electronic signals and image capture, establishing a record of the vehicle's location and the hijacker's appearance before any alarm signals are generated. This ensures recovery reliability is maintained even if alarm signals are delayed or suppressed.
Solution Approach 2:
The system provides continuous feedback through electronic signal transmission and image capture that confirms the hijacking event and tracks the vehicle's movement. This feedback mechanism maintains recovery reliability by providing law enforcement with real-time location and identification data without requiring immediate activation of loud alarm signals.
3Difficulty of detecting and measuring
If multiple signal types are generated simultaneously, then the vehicle's detectability is improved, but the complexity of the safety system increases
Solution Approach 1:
The safety system integrates multiple signal generation functions into a single unified system that can operate in different modes. The same control unit manages electronic signal transmission, image capture, and audible/visual alarm generation, allowing the system to perform multiple functions without proportionally increasing complexity. The system can activate different signal types based on the situation.
Solution Approach 2:
The system dynamically adjusts which signal types are activated based on the detected situation. Upon detecting unauthorized possession, the system can selectively activate electronic signals and image capture immediately, then subsequently activate audible and visual alarm signals. This dynamic activation pattern maintains high detection capability while managing system complexity through conditional signal generation.

AI summary
A method of, and safety system usable in, responding to an unauthorized possession of a vehicle configured to transport at least one person, including the steps of: obtaining the vehicle with the safety system associated therewith, the safety system configured to at least one of: a) generate at least one form of detectable signal; b) generate an electronic signal; and c) generate at least one image of a person in/on the vehicle; and generating an input to cause the system to generate at least one of: i) the at least one form of detectable signal that can be sensed by persons in the vicinity of the vehicle; ii) the electronic signal; and iii) the at least one image of a person in/on the vehicle. The system is configured so that at least one of the at least one form of detectable signal, the electronic signal, and the at least one image is generated after a time delay following the generation of the input to the safety system.
