Bluetooth Signal Splitter for Vehicle Lighting Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for controlling vehicle interior ambient lighting to match music rhythm face issues such as high noise interference, poor synchronization between light and music, and incompatibility with third-party music apps, leading to a poor user experience.
Innovation Solution
A control module that converts a single Bluetooth signal into multiple signals, comprising a receiving chip and a transmitting chip, which communicate with audio input and output devices respectively, allowing for precise synchronization of light and music effects without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If microphones pick up external sounds to control lighting rhythm, then the lighting can respond to music, but noise interference increases and synchronization accuracy deteriorates
Solution Approach 1:
The patent introduces Bluetooth technology as an intermediary to transmit music signal data directly from the audio source to the lighting control system. This mediator eliminates the need for microphones to pick up sound, thereby avoiding noise interference while maintaining accurate rhythm synchronization. The Bluetooth transmission serves as a clean channel that delivers precise timing information without environmental noise contamination.
2Measurement precision
If BLE technology is used to transmit music data locally, then lighting can synchronize with music, but compatibility with third-party music apps deteriorates
Solution Approach 1:
The patent implements a universal Bluetooth interface that can communicate with multiple types of music applications and audio devices simultaneously. The control module is designed to work with any Bluetooth-enabled audio source, whether it's a third-party music app, online streaming service, or local audio file player. This multi-functionality approach allows the system to maintain accurate synchronization while being compatible with diverse music sources without requiring separate solutions for each app.
3Device complexity
If a single Bluetooth signal is used for both audio transmission and lighting control, then device complexity is reduced, but signal interference increases
Solution Approach 1:
The patent segments the single Bluetooth signal into separate functional channels within the control module. The received Bluetooth signal is divided into distinct data streams: one for audio playback and another for lighting control parameters including rhythm and timing information. This internal segmentation allows simultaneous processing of audio and lighting control functions through the same Bluetooth interface without mutual interference, as each function operates on its dedicated data channel.
