URI-Based Mobile Device Pairing for In-Vehicle Infotainment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for pairing wireless devices with other electronic devices or vehicles are cumbersome and time-consuming, often requiring user accounts and manual entry of vehicle identification numbers.
Innovation Solution
A URI-based system that uses a cloud service to authorize pairing between a mobile device and a host device, such as an in-vehicle infotainment system, allowing for local wireless pairing without an Internet connection, utilizing QR codes or NFC tags to simplify and secure the setup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pairing methods are used (entering vehicle identification numbers, setting up user accounts), then pairing can be established, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The system pre-generates unique identifiers and pairing codes for each vehicle before the pairing process begins. These pre-prepared credentials are stored in the vehicle's system, allowing for rapid authentication when a mobile device attempts to pair, eliminating the need for manual entry of vehicle identification numbers or account setup during the pairing moment.
Solution Approach 2:
The patent introduces an online portal and unique identifier system as an intermediary between the vehicle and mobile device. Instead of direct manual pairing, the system uses these intermediate elements to facilitate automated authentication and pairing, streamlining the process while maintaining security.
2Reliability
If cloud service authorization is implemented for pairing, then security and automation are improved, but system complexity increases
Solution Approach 1:
The vehicle system automatically generates and manages its own unique identifiers and pairing credentials without requiring complex external configuration. The system serves itself by maintaining local authentication data and autonomously initiating pairing protocols, reducing the need for complex centralized management infrastructure.
Solution Approach 2:
The patent designs a universal pairing system that can authenticate multiple mobile devices against a single vehicle using the same infrastructure. The online portal and unique identifier mechanism serve multiple functions: device authentication, vehicle identification, and pairing coordination, thereby managing complexity through multi-functionality rather than separate specialized systems.
3Adaptability or versatility
If Internet connection is required for pairing, then cloud-based authorization and device detection are enabled, but deployment costs and connectivity requirements increase
Solution Approach 1:
The system performs device detection and authorization actions in advance through the online portal before the actual pairing occurs. Mobile device types are identified and appropriate applications are directed to be installed beforehand, so that when local pairing occurs, all detection and authorization work is already complete, enabling offline functionality.
Solution Approach 2:
The patent divides the pairing process into two distinct segments: an online phase for device detection, authorization, and application distribution, and an offline phase for actual local wireless pairing. This segmentation allows the system to leverage Internet connectivity only when necessary for initial setup, while the core pairing function operates independently without continuous connectivity requirements.

AI summary
Systems and methods directed to URI-based host to mobile device setup and pairing are described herein. A uniform resource identifier (URI) may be received from a host device. A request for an application associated with the host device and the wireless device may be transmitted based at least in part on the URI. The requested application may be received. An association with the host device may be established based at least in part on the application.
