Mobile Phone Power Mode Detector for Vehicle Alarm Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle alarm systems often trigger false alarms due to misinterpretation of stimuli, leading to user desensitization and reduced effectiveness in deterring theft, as they cannot differentiate between legitimate and false alerts, causing annoyance and loss of trust in the security system.
Innovation Solution
A mobile phone-based alert notification system that detects changes in power mode, such as when a car alarm activates, and sends notifications to the owner via SMS or other means, distinguishing between legitimate and false alarms by monitoring power source changes, thereby reducing false alerts and enhancing alert reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional alarm systems use audible sirens to alert owners, then the alarm can be heard by persons standing several hundred yards away, but the alarm becomes so ubiquitous that people become desensitized and ignore it, reducing its effectiveness
Solution Approach 1:
The patent extracts the notification function from the local audible alarm and transfers it to a remote cellular phone notification system. The alarm siren remains for local deterrence, but the owner notification is separately handled through cellular messages, allowing the notification function to be isolated from the alarm sound itself.
Solution Approach 2:
The patent introduces a cellular phone as an intermediary between the alarm system and the owner. Instead of directly notifying the owner through audible alarm, the system uses cellular messaging as a mediator to deliver alerts, thereby avoiding the desensitization problem of direct audible notification.
2Adaptability or versatility
If alarm sensors detect various stimuli to trigger alerts, then the system can respond to multiple security threats, but the system cannot differentiate between legitimate and false alerts, causing frequent false alarms
Solution Approach 1:
The patent applies local quality by making different parts of the alarm system have different functions. The sensor section remains versatile for detecting multiple threats, while the notification section selectively activates based on the specific type and legitimacy of the detected stimulus, allowing each part to optimize its performance.
Solution Approach 2:
The patent changes the notification parameter from a uniform audible alarm to differentiated cellular messages based on the detected stimulus. By analyzing the characteristics of the detected event and changing the notification response accordingly, the system can distinguish between legitimate and false alerts while maintaining versatile detection capabilities.
3Reliability
If alarm systems frequently activate to deter theft, then the security deterrent effect is maintained, but users become annoyed and disable their security units, reducing security coverage
Solution Approach 1:
The patent replaces the mechanical audible alarm notification system with an electronic cellular communication system. This substitution allows for more controlled and selective notification, reducing unnecessary user exposure to alarm sounds while maintaining security effectiveness through targeted digital notifications.
Solution Approach 2:
The cellular phone notification serves as an intermediary that filters and selectively delivers alarm information to users. This intermediary layer prevents direct exposure to frequent alarm activations that cause user annoyance, while still maintaining security effectiveness by notifying users of legitimate threats.
