Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle activity monitoring systems fail to effectively alert trailing vehicles to braking or turn signals of leading vehicles, especially under poor visual conditions, leading to delayed reaction times and increased risk of collisions, particularly in congested zones or peak driving times.
Innovation Solution
A vehicle-to-vehicle communication system that includes an emitter and receiver configured to detect and transmit signal use conditions, such as brake or turn signals, using electromagnetic radiation sources like lasers or LEDs, with adjustable beam width and strength to ensure reliable communication within a lane, and a traffic analysis module to optimize traffic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual signal transmission (brake lights, turn signals) is used for vehicle-to-vehicle communication, then the system is simple and uses existing infrastructure, but the signal reliability deteriorates under poor visual conditions such as fog, heavy rain, or when obscured by intervening vehicles
Solution Approach 1:
The patent introduces an intermediary communication system that uses electromagnetic radiation (radio waves, microwaves, or optical beams) as a mediator to transmit signal use conditions between vehicles. This intermediary transmission method bypasses the limitations of direct visual contact, allowing signals to penetrate fog, rain, and obstacles that block line-of-sight visual communication between vehicles.
2Reliability
If electromagnetic radiation sources (lasers, LEDs) with adjustable beam width and strength are used for vehicle-to-vehicle communication, then the communication reliability improves, but the device complexity increases
Solution Approach 1:
The patent employs parameter changes by making the beam width and strength of electromagnetic radiation sources adjustable. This allows the system to optimize communication reliability for different driving conditions - narrowing the beam for focused lane-to-lane communication or expanding it for broader coverage, and adjusting strength based on distance and environmental conditions - without requiring fundamentally different hardware architectures.
3Loss of time
If driver reaction time is improved through timely alerts, then collision risk is reduced, but the system complexity increases due to additional monitoring and communication components
Solution Approach 1:
The patent implements multi-functionality by designing a system where the same communication infrastructure serves multiple purposes: transmitting brake signal use conditions, turn signal use conditions, and other vehicle status information. This universal approach allows the system to provide comprehensive driver alerts and monitoring capabilities without requiring separate dedicated systems for each function, thereby reducing overall complexity while improving reaction time.
