Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LiFi technologies do not effectively provide location-based content delivery to vehicles, especially in dynamic traffic situations, where real-time traffic information and alternative route recommendations are not efficiently communicated using visible light communication systems.
Innovation Solution
A LiFi transceiver system that includes a vehicle transceiver coupled to a vehicle and column transceivers along roads, using digital signal processors, LEDs, and photodiodes to encode and decode vehicle identifiers and location-based content, enabling real-time traffic pattern analysis and alternative route recommendations through an internet protocol network, with hand-over algorithms for seamless content streaming as the vehicle moves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If LiFi transceivers use visible light communication to transmit data to vehicles, then radio wave interference is eliminated, but location-based content delivery in dynamic traffic situations is not effectively provided
Solution Approach 1:
The system implements dynamic hand-over algorithms that enable seamless switching between multiple LiFi transceivers as vehicles move through different locations. The source LiFi transceiver changes dynamically based on vehicle position, allowing continuous content delivery while adapting to dynamic traffic situations and eliminating radio wave interference through visible light communication
Solution Approach 2:
The LiFi transceiver system serves multiple functions: it transmits location-based content to vehicles, tracks traffic patterns by determining vehicle locations, provides alternative route recommendations, and eliminates radio wave interference. This multi-functional approach resolves the contradiction by making the system both interference-free and highly adaptable to various traffic scenarios
2Adaptability or versatility
If multiple LiFi transceiver units are deployed along roads to enable location-based content delivery, then content streaming capability is improved, but system complexity increases
Solution Approach 1:
The system divides the road network into multiple segments, each served by individual LiFi transceiver units positioned at strategic locations such as traffic lights and intersections. This segmentation allows content delivery coverage to be improved through distributed transceivers while managing system complexity by creating modular, independently operable units that work together through standardized hand-over protocols
