In-Car Wireless Connectivity Unit for Multi-Device Audio Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle infotainment systems lack flexibility and customizability, limiting simultaneous data sharing and personalized audio experiences for multiple occupants, with Bluetooth typically allowing only one device to connect at a time.
Innovation Solution
Implementing a wireless connectivity unit with multiple Bluetooth controllers and an ultra-wideband (UWB) transceiver to enable simultaneous connections and data sharing among multiple devices, allowing personalized audio experiences for each occupant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single Bluetooth controller is used in the IVI system, then the device complexity is reduced, but the system can only connect to one mobile device at a time, limiting simultaneous data sharing among multiple occupants
Solution Approach 1:
The patent divides the wireless communication functionality into multiple independent Bluetooth controllers (at least two) within the IVI system. Each Bluetooth controller can independently connect to and communicate with a different mobile device simultaneously, enabling multiple occupants to share data and audio streams without interference. This segmentation resolves the contradiction by trading increased device complexity for enhanced adaptability and simultaneous connection capability.
2Productivity
If Bluetooth is used for wireless communication, then short-range data transmission is enabled, but simultaneous data transfer between multiple devices and the IVI is not possible
Solution Approach 1:
The patent implements multiple Bluetooth controllers that operate independently to handle simultaneous data transfers with multiple mobile devices. Each controller manages its own connection and data stream, enabling parallel communication operations. This segmentation allows the system to maintain high data transfer efficiency while simultaneously supporting multiple device connections, resolving the contradiction between productivity and adaptability.
3Adaptability or versatility
If one mobile device is connected to the IVI via Bluetooth, then audio data can be transmitted to that device, but other occupants cannot access or stream data through their own devices simultaneously
Solution Approach 1:
The patent segments the audio streaming functionality by providing each occupant with a dedicated Bluetooth controller connection to their personal mobile device. Each device can independently receive and process audio data streams from the IVI system simultaneously. This segmentation enables personalized audio streaming for multiple occupants while managing the increased connectivity complexity through independent communication channels.
Solution Approach 2:
The IVI system is designed with universal multi-functionality by supporting multiple Bluetooth controllers that can each handle different types of data transfers (audio, video, files) with different mobile devices simultaneously. This multi-functional architecture allows the system to adapt to various usage scenarios and occupant preferences without requiring separate specialized systems, resolving the contradiction between adaptability and complexity.
