Solution Overview
Problem
Existing telematics systems for unpowered vehicles lack effective methods to monitor and respond to adverse conditions, tampering, or maintenance issues, particularly in trailers and other unpowered vehicles, which are often remote and difficult to track.
Innovation Solution
Implementing wireless communication devices with sensors, such as hall-effect sensors and pressure sensors, to detect changes in magnetic fields or pressure within sealed volumes, triggering alerts via long-range networks when tampering or maintenance criteria are violated, and using Bluetooth Low Energy beacons for short-range communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication devices with sensors are implemented in unpowered vehicles, then monitoring capability and security awareness are improved, but device complexity and power management requirements increase
Solution Approach 1:
The patent combines multiple sensors (hall-effect sensors, pressure sensors), wireless communication capabilities, and telematics functions into a single integrated wireless communication device that can be installed in unpowered vehicles. This merging approach improves monitoring capability while managing complexity through consolidation of components into one unified device rather than separate systems.
Solution Approach 2:
The wireless communication device is designed to perform multiple functions including detecting magnetic field changes via hall-effect sensors, detecting pressure changes via pressure sensors, transmitting data via wireless communication, and providing various alerts. This multi-functional design allows a single device to provide comprehensive monitoring capabilities across different vehicle types and conditions.
2Reliability
If real-time monitoring and alerting systems are implemented, then security and maintenance awareness are enhanced, but energy consumption increases
Solution Approach 1:
The system implements periodic monitoring and alerting rather than continuous operation. The wireless communication device can be activated periodically or event-driven, transmitting data and alerts only when needed. This periodic action approach maintains security awareness while significantly reducing energy consumption compared to continuous monitoring systems.
Solution Approach 2:
The system uses event-triggered alerts where the device automatically activates monitoring and transmission functions when specific conditions are detected (such as tampering or adverse conditions). This self-service approach ensures security awareness is maintained when needed while minimizing energy consumption during normal operation.
3Measurement precision
If multiple sensors are integrated into the wireless communication device, then detection precision and monitoring accuracy are improved, but manufacturing complexity increases
Solution Approach 1:
The patent integrates multiple sensor types (hall-effect sensors for magnetic field detection, pressure sensors for pressure changes) along with wireless communication components into a single manufactured device. This merging approach improves detection precision across multiple parameters while managing manufacturing complexity through consolidated production processes rather than assembling separate components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables real-time monitoring and alerting of adverse conditions or tampering in unpowered vehicles, enhancing security and maintenance awareness through integrated telematics systems.
Implementation Method 1
The at least one sensor may be a hall effect sensor located with respect to a magnet search that movement of the at least one wireless communication device with respect to the vehicle causes a disturbance of magnetic field measured by the hall effect sensor
Implementation Method 2
The light device may comprise the at least one sensor inside the inner volume, wherein the at least one sensor comprises at least one barometric pressure sensor, and wherein the at least one analyzed sensor signal being determined to satisfy the at least one sensor signal criterion corresponds to the internal pressure changing by an amount equal to, or greater than, a configured pressure change value
Data Source
AI summary
A taillight assembly comprising long-range radio module/circuitry, GNSS location determination circuitry, and secondary short-range radio module/circuitry may be configured to receive messages from various sensors, equipment, and cargo to verify proper operating conditions, determine or notify of potential theft, and facilitate cargo carriage. The short-range and long-range modules may comprise authentication checking to authenticate messages and the priority of messages. Sensors of the taillight assembly may be used to determine removal of, or damage to, the taillight assembly. Remote sensors may be used to transmit, to the short-range module, information indicative of removal or theft of the trailer from a towing vehicle or other condition, and the long-range circuitry may transmit an indication of the theft, removal, or condition, to a third party. Circuitry of the taillight assembly may be powered by a battery within the taillight assembly that is charged during operation of the taillight.
