Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle intrusion detection systems are inadequate due to outdated technology, leading to ineffective alarm notifications and sensitivity issues, as well as inability to adapt security levels based on dynamic environments, resulting in inappropriate security monitoring and response.
Innovation Solution
A security system comprising sensors, transceivers, and a computing device that determines the vehicle's location and adjusts settings based on predefined categories, transitioning into an armed mode to detect intrusions and alert the owner or emergency services, while also managing power consumption and communication with remote devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional audio-only alarm systems are used, then the alarm can be heard by those nearby, but the alarm is frequently ineffective for alerting the vehicle owner and causes confusion due to false alarms from environmental factors
Solution Approach 1:
The patent introduces a remote device as an intermediary between the alarm system and the vehicle owner. The remote device receives alarm signals wirelessly and delivers them to the owner's mobile device, bypassing the limitation of audio-only local alarms. This mediator ensures reliable notification of the vehicle owner regardless of their proximity to the vehicle.
Solution Approach 2:
The patent replaces the traditional mechanical/audio-based alarm system with an electronic communication system. Instead of relying solely on acoustic signals that are subject to environmental interference, the system uses wireless electronic communication (Bluetooth, Wi-Fi, cellular) to transmit alarm notifications, eliminating false alarms caused by environmental factors like loud noises or strong winds.
2Adaptability or versatility
If fixed security levels are maintained, then the system is simple to operate, but the system cannot adapt to dynamic security needs in different locations
Solution Approach 1:
The patent implements dynamic security levels that automatically adjust based on the vehicle's location. The system uses GPS positioning to determine if the vehicle is in a high-risk area (such as near gas stations or in unfamiliar locations) and automatically increases security monitoring and alarm sensitivity accordingly. This dynamic adaptation allows the system to respond to changing security needs without requiring manual user intervention.
Solution Approach 2:
The system continuously monitors the vehicle's location and security conditions, receiving feedback from GPS and environmental sensors. Based on this feedback, the system automatically adjusts security parameters such as alarm sensitivity, monitoring frequency, and notification methods. This closed-loop feedback mechanism enables adaptive security while maintaining automated operation that masks the underlying complexity from the user.
3Reliability
If continuous monitoring is performed, then intrusion detection capability is maximized, but power consumption increases
Solution Approach 1:
The patent implements periodic monitoring cycles where sensors are activated at regular intervals rather than continuously. The system monitors for intrusion attempts by periodically checking sensor states and only activates full monitoring modes when potential threats are detected. This periodic action maintains intrusion detection capability while significantly reducing average power consumption during normal operation.
Solution Approach 2:
The system dynamically changes operational parameters based on detected conditions. During normal operation, monitoring intensity is reduced to conserve power. When intrusion indicators are detected (such as unauthorized proximity or sensor triggers), the system increases monitoring frequency and sensitivity. This parameter adjustment allows the system to maintain high detection capability when needed while minimizing power consumption during safe periods.

AI summary
A sensing device can include an accelerometer, a transceiver, and a computing device in communication with the accelerometer and transceiver. The computing device can transmit a first set of signals at a first power level to a remote device. The computing device can determine, via the accelerometer, a movement of the sensing device. The computing device can increase a power level for transmission from the first power level to a second power level in response to the movement. The computing device can transmit future signals at the second power level to the remote device.
