Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Vehicle-to-Everything (V2X) communication technologies, such as IEEE 802.11p and Cellular V2X (C-V2X, are not interoperable, leading to dual existence of both technologies in small-scale deployments, which hinders interoperability between vehicles using different technologies, increasing implementation costs and reducing safety and efficiency.
Innovation Solution
A vehicle communication system that dynamically configures its antennas based on location and network data to operate in multiple V2X technologies, enabling intelligent switching between 802.11p and C-V2X, improving overall operability and safety through machine learning and adaptive antenna management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple V2X technologies (802.11p and C-V2X) are deployed simultaneously, then communication coverage and technology compatibility are improved, but system complexity and implementation costs increase
Solution Approach 1:
The patent implements dynamic antenna configuration where the antenna system can switch between different configurations based on the operating V2X technology. The antenna impedance and radiation patterns are dynamically adjusted using programmable impedance matching networks and antenna array phase shifters, allowing the same physical antenna structure to adapt to both 802.11p and C-V2X requirements without requiring separate fixed antenna systems for each technology
Solution Approach 2:
The patent designs a universal antenna system that can serve multiple V2X technologies through software-defined radio architecture. A single antenna array with reconfigurable beamforming capabilities replaces multiple dedicated antenna systems, enabling the vehicle to communicate with infrastructure using either 802.11p or C-V2X protocols while sharing the same hardware platform
2Reliability
If separate antenna systems are used for each V2X technology, then technology-specific performance is optimized, but interoperability and implementation cost increase
Solution Approach 1:
The patent merges multiple V2X antenna systems into a single integrated antenna array with combined beamforming capabilities. The system uses a shared signal processing platform that can generate technology-specific beam patterns for both 802.11p and C-V2X, eliminating the need for separate antenna assemblies while maintaining optimized performance for each protocol through software-controlled phase and amplitude modulation
3Device complexity
If fixed antenna configuration is used, then system simplicity is maintained, but adaptability to different communication environments and technologies is reduced
Solution Approach 1:
The patent employs parameter-changed antenna design where physical antenna characteristics such as impedance, resonant frequency, and radiation direction are made variable through electronic control. Programmable impedance matching networks allow real-time adjustment of antenna input impedance to match different V2X transceiver requirements, while phase shifters and amplitude controllers modify the effective radiation pattern to optimize performance for various communication scenarios and technology protocols
