Multipurpose Event Detection Sensor for Automotive Alarm Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern automotive alarm systems are limited in their ability to detect and notify remote devices of events, providing only basic information without detail on the nature, location, or severity of the event, and lack wireless communication capabilities to transmit alerts.
Innovation Solution
A multipurpose event detection sensor system comprising sensors, a processor, and communication means that detect events, analyze data, generate detailed alert messages, and transmit them to a remote processing system via wireless communication, using components like accelerometers, microphones, and hall effect sensors to provide granular information on event type, severity, and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional automotive alarm systems are used, then basic event detection is provided, but detailed information about event type, location, and severity cannot be provided
Solution Approach 1:
The system divides event detection into multiple specialized sensor components: impact sensors for collision detection, glass break sensors for window intrusion, tilt sensors for vehicle movement, and remote sensors for external monitoring. Each sensor type captures specific event characteristics, and their combined data provides comprehensive event information without requiring a single complex sensor system.
Solution Approach 2:
The alarm system integrates multiple sensor types and communication capabilities into a single platform that can detect various event types (impact, glass break, tilt, remote presence) and transmit alerts through multiple channels (wireless communication, cellular networks). This multi-functional approach allows one system to provide detailed event information across different scenarios without requiring separate specialized systems.
2Adaptability or versatility
If traditional alarm systems are used, then local alerts are provided, but remote notification capability is lacking
Solution Approach 1:
The system introduces wireless communication modules and cellular network interfaces as intermediaries between the local sensor system and remote users. These communication components translate sensor data into transmittable alert formats and relay them through available networks, enabling remote notification without requiring direct integration between sensors and end-user devices.
Solution Approach 2:
The alarm system incorporates multiple communication methods (wireless transmitters, cellular modems, network interfaces) that can operate independently or in combination. This multi-channel communication capability ensures remote notification functionality across different environments and network conditions while maintaining system versatility.
3Loss of information
If simple alarm systems are used, then basic alerting is provided, but granular event information cannot be transmitted
Solution Approach 1:
The system segments event measurement into distinct parameters handled by specialized sensors: impact force and direction from impact sensors, glass break frequency and intensity from acoustic sensors, tilt angle and orientation from tilt sensors. This segmentation allows precise measurement of each event characteristic while maintaining overall system manageability through modular sensor integration.
