V2X Safety Triangle Reflectors for Multi-Channel Failure Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety warning triangle reflectors have limited ability to warn incoming vehicles due to weak reflection lights and low visibility, leading to high risks of vehicle failures and traffic congestion.
Innovation Solution
A Vehicle-to-Everything (V2X) enabled safety triangle warning reflector that receives and stores vehicle information locally, generates failure messages without a wireless connection, and broadcasts them on multiple channels, including cloud, infrastructure, and personal communication service channels, to alert surrounding vehicles and traffic systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional safety warning triangle reflectors are used, then the device structure remains simple, but the warning effectiveness is insufficient due to weak reflection lights and low visibility
Solution Approach 1:
The patent combines multiple functions into a single device: the warning triangle integrates V2X communication transceiver, GPS location module, reflective surfaces, and warning lights. This merging of communication technology, location tracking, and traditional warning functions resolves the contradiction by achieving reliable warning effectiveness through multi-functional integration while maintaining a unified portable device structure.
Solution Approach 2:
The warning triangle becomes a universal device that performs multiple functions: traditional passive reflection, active light emission, V2X communication with surrounding vehicles, GPS location tracking, and emergency service notification. This multi-functionality directly improves warning effectiveness while the device remains a single portable unit, resolving the technical contradiction.
2Area of stationary object
If the warning reflector operates only within wireless connection range, then the device complexity remains low, but the warning coverage is limited to the operating field of the wireless connection
Solution Approach 1:
The patent extends warning coverage from the limited two-dimensional wireless connection range to a broader spatial dimension by integrating GPS location tracking and V2X communication networks. The device can broadcast warning information beyond direct wireless range through infrastructure-based communication, achieving wide-area coverage while maintaining a relatively simple portable device structure.
3Loss of information
If multiple communication channels are used for broadcasting, then the information reach is improved, but the device complexity increases
Solution Approach 1:
The patent uses infrastructure elements (roadside units, traffic signals, navigation systems) as intermediaries to relay and amplify warning information. The warning triangle broadcasts initial signals through multiple channels, and these infrastructure intermediaries receive, process, and redistribute the information, achieving reliable information delivery across multiple channels while keeping the portable device itself relatively simple.
Data Source
AI summary
In various embodiments, methods, systems, and vehicle apparatuses are provided. The method includes receiving, via an interface of the V2X enabled safety triangle warning reflector, vehicle information before deployment for storing the vehicle information in a memory disposed locally at the V2X enabled safety triangle warning reflector for subsequent use at the deployment; generating, by a processor chip in communication with the memory, a failure message associated with the vehicle failure based at least on the vehicle information contained locally in memory; and broadcasting, the failure message generated by the processor chip via a transmitter disposed of in the V2X enable safety triangle warning reflector during a vehicle failure, wherein the failure message is broadcasted in a surrounding area of the failure vehicle on a set of multiple different channels including cloud, infrastructure and personal communication service (PCS) channels to entities that provide traffic and vehicle control.
