External Vehicle Audio Messaging With Custom Speech Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems lack the ability to customize and deliver audible messages to pedestrians and motorists in proximity to the vehicle, failing to effectively convey important information.
Innovation Solution
A customizable external vehicle communication system comprising an electronics module, sound transducer, and playback activation control, which converts digital messages from text to speech and delivers them externally via a sound transducer, utilizing a speech-to-text converter, text-to-speech converter, and memory modules to store and control the operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a customizable external vehicle communication system is implemented, then the ability to deliver audible messages to pedestrians and motorists is improved, but the device complexity increases due to multiple conversion modules and memory components
Solution Approach 1:
The system is divided into distinct functional modules: speech-to-text converter, text-to-speech converter, memory module, and sound transducer. Each module performs a specific function, making the complex system manageable and maintainable while achieving customizable message delivery
Solution Approach 2:
The electronics module serves multiple functions by integrating speech-to-text conversion, text-to-speech conversion, and message storage capabilities within a single system, allowing the vehicle to both record custom messages and play them back audibly
2Adaptability or versatility
If speech-to-text and text-to-speech conversion capabilities are added, then the customization of audible messages is improved, but the manufacturing complexity increases
Solution Approach 1:
The conversion capabilities are implemented as separate converter modules that can be independently manufactured and tested before assembly into the final system, simplifying the manufacturing process while maintaining customization functionality
Solution Approach 2:
The electronics module acts as an intermediary that handles the complex conversion processes, shielding the manufacturing process from the complexity of speech-to-text and text-to-speech conversions while still enabling message customization
3Adaptability or versatility
If multiple memory modules are used to store digital messages, then the versatility of stored messages is improved, but the device complexity increases
Solution Approach 1:
Multiple memory modules are combined into a unified storage system managed by the electronics module, providing increased storage capacity while presenting a simple interface to the rest of the system, thus avoiding proportional increases in overall complexity

Data Source
AI summary
The customizable external vehicle communication system includes an electronics module, a sound transducer, and a playback activation control. Responsive to depressing the playback activation control located within a vehicle, the customizable external vehicle communication system may communicate an audible message to pedestrians and/or motorists who may be in proximity to the vehicle. The audible message may be delivered external to the vehicle via the sound transducer. The audible message may be customized and may result from the conversion of a digital message from text to speech. The digital message may be one of several messages stored in one or more memory modules within the electronics module. The digital messages may be created by typing the digital message into the customizable external vehicle communication system or by converting a user's speech from speech to text.
