Vehicle Hazard Consensus Alerts for Nearby Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle alert systems do not effectively communicate dangerous situations to devices or pedestrians outside the vehicle, leading to potential safety risks due to limited inter-device communication and lack of consensus validation.
Innovation Solution
A method and system for vehicles to receive data from proximate devices, determine dangerous situations through consensus validation with other vehicles and devices, and notify devices of potential hazards, utilizing a server for data analysis and notification distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle alert systems use traditional annunciations (audible/visual alerts within the vehicle), then the system complexity remains low, but the safety effectiveness deteriorates because devices outside the vehicle cannot be notified
Solution Approach 1:
The patent introduces a server as an intermediary component that receives data from multiple vehicles, determines dangerous situations through consensus, and distributes notifications to devices. This mediator architecture enables external device notification without requiring direct peer-to-peer communication between vehicles and external devices, thus improving safety effectiveness while managing system complexity through centralized coordination
Solution Approach 2:
The system enables vehicles to perform multiple functions: not only internal alerting but also external device notification and consensus-based dangerous situation validation. The server provides multi-functional capabilities including data aggregation, analysis, consensus determination, and notification distribution, allowing a single system to address multiple safety requirements simultaneously
2Reliability
If the system notifies devices outside the vehicle about dangerous situations, then the safety coverage improves, but the difficulty of detecting and validating dangerous situations increases due to the need for consensus
Solution Approach 1:
The patent merges data from multiple vehicles and devices into a unified analysis process at the server. By combining inputs from multiple sources to determine dangerous situations through consensus, the system achieves broader safety coverage while distributing the validation burden across multiple participants rather than requiring a single complex detection system
Solution Approach 2:
The consensus mechanism provides feedback loops where multiple vehicles and devices validate dangerous situation determinations before notification. This feedback process ensures higher reliability by confirming dangerous situations through multiple independent observations, while the automated server-based implementation manages the complexity of coordination
3Measurement precision
If the system uses consensus validation from multiple devices and transports, then the accuracy of dangerous situation detection improves, but the response time deteriorates due to additional validation steps
Solution Approach 1:
The server continuously collects and pre-processes data from multiple vehicles and devices before dangerous situations occur. This preliminary data aggregation and analysis prepare the system for rapid consensus determination when actual dangerous situations arise, improving detection accuracy while minimizing response time delays
Solution Approach 2:
The system implements a threshold-based consensus mechanism where notification occurs when a sufficient number of participants confirm a dangerous situation, rather than requiring complete agreement from all possible sources. This partial consensus approach achieves high detection accuracy while avoiding the time delays of exhaustive validation
Data Source
AI summary
An example operation includes one or more of receiving data, by a transport, from a device in proximity to the transport, the data comprises one or more of a speed, a direction, and a distance of the device from the transport, determining, by the transport, a dangerous situation based on the data, obtaining consensus, by the transport, to validate the dangerous situation from one or more of: one or more other devices proximate to the transport, and one or more other transports proximate to the transport, and notifying the device, by the transport, based on the consensus, the notification comprises the dangerous situation.
