Vehicle Occupant Communication Using Wireless Audio Without Door Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for communicating with vehicle occupants require opening windows or doors, exposing individuals to weather, safety risks, and potential disease transmission, especially during interactions with law enforcement or at drive-through establishments.
Innovation Solution
A two-way communication system using short-range radio transmission via Bluetooth or Wi-Fi between vehicles, enabling voice and data exchange without requiring physical access, utilizing transceivers and cellphones for secure and encrypted communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the occupant opens the window or door to communicate, then communication is established, but the occupant is exposed to weather, safety risks, and potential disease transmission
Solution Approach 1:
The patent introduces an intermediary communication system consisting of a microphone, amplifier, and speaker mounted on the vehicle exterior. This intermediary system allows the occupant to communicate with outsiders without opening the window or door, thereby maintaining protection against weather and safety risks while establishing effective communication
Solution Approach 2:
The patent replaces the mechanical system of opening windows or doors with an electronic/acoustic system comprising microphones, amplifiers, and speakers. This substitution eliminates the need for physical window/door opening while maintaining communication capability
2Device complexity
If the speaker quality is inadequate or microphone position is poor, then communication equipment is simple, but clear understanding of the occupant's message is difficult
Solution Approach 1:
The patent applies preliminary action by pre-positioning the microphone at the optimal location on the vehicle exterior and pre-adjusting the amplifier gain settings to ensure clear capture and transmission of the occupant's voice before communication begins, thereby preventing information loss
Solution Approach 2:
The patent creates an accurate acoustic copy of the occupant's voice through the microphone-amplifier-speaker system, transmitting the voice signal externally while maintaining fidelity and clarity of the original message
3Ease of operation
If the officer exits the vehicle to retrieve driver information and access computer systems, then communication and data access are achieved, but the officer is exposed to infectious diseases and increased safety risks
Solution Approach 1:
The patent introduces an intermediary wireless communication system that allows the officer to access driver information and communicate with the occupant without exiting the vehicle. The system uses wireless data transmission to bridge the gap between the officer's computer system and the vehicle's communication system, eliminating the need for physical exposure
4Productivity
If the initial confrontation with the driver is required, then law enforcement procedures are completed, but the officer faces life-threatening situations
Solution Approach 1:
The patent introduces an intermediary communication system that allows the officer to conduct initial confrontation and information gathering procedures without direct physical contact with the driver. The system maintains law enforcement productivity by enabling verbal communication and information exchange while significantly improving officer safety by eliminating the need for close proximity confrontation
Data Source
AI summary
A method of communicating between a person within a target vehicle and a law-enforcement person includes establishing a connection between a law-enforcement transceiver and a target vehicle transceiver using a protocol and encoding an audio signal into an encoded audio signal by the law-enforcement transceiver using the protocol, The encoded audio signal is transmitted from the law-enforcement transceiver and received by the target vehicle transceiver where the encoded audio signal is accepted by the target vehicle transceiver through a feature in the protocol, the feature in the protocol allowing limited access to an audio transducer of the target vehicle, the encoded audio signal is decoded back into the audio signal by the target vehicle transducer and the audio signal is reproduced on the audio transducer within the target vehicle.
