Vehicle Horn Directional Sound Wave Modulation for Targeted Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems between vehicles lack directionality, making it difficult to achieve targeted communication, especially in complex transportation networks where conventional methods require visual identification of vehicles and struggle with movement and shielding issues.
Innovation Solution
A system and method for directional vehicle communication using a smart apparatus that acquires target information and transmission direction information, modulating this information onto a sound wave signal and sending it to a specific vehicle, allowing for directional transmission and reception, enabling vehicles to establish communication based on relative position and identifier information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional communication networks are used for vehicle communication, then communication infrastructure is available, but directionality and targeted communication are lost
Solution Approach 1:
The patent introduces sound wave signals as an intermediary carrier to transmit vehicle information. The sound wave acts as a mediator between the transmitting vehicle and receiving vehicle, enabling directional communication by directing sound waves toward specific targets while maintaining communication reliability through the structured transmission and reception process
2Ease of operation
If visual identification methods are used to target vehicles, then communication can be established, but movement and shielding cause communication failures
Solution Approach 1:
The patent replaces visual identification methods with sound wave-based directional transmission. Instead of relying on mechanical line-of-sight visual contact that is vulnerable to shielding and movement, the system uses sound wave propagation characteristics to maintain reliable directional communication even when vehicles are in motion or partially obscured
3Ease of operation
If sound wave signals are used for directional transmission, then targeted communication is achieved, but signal modulation and direction control complexity increases
Solution Approach 1:
The patent makes the horn serve multiple functions: it acts as both a vehicle warning device and a communication transmitter. By modulating vehicle information onto sound wave signals generated by the existing horn system, the invention avoids adding dedicated transmission hardware, thereby reducing overall system complexity while achieving targeted communication
