Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing a wireless connection between a mobile device and a vehicle's information system is complex and often requires active pairing, which can be a barrier for users, especially in scenarios where multiple vehicles are used within short periods, such as rental cars or car sharing, leading to increased costs and difficulty in utilizing infotainment functions.
Innovation Solution
An apparatus with a first communication module for vehicle-specific data transmission and a second module for mobile device communication, utilizing communication parameters like MAC addresses to simplify the connection setup, allowing for automated pairing and broadband Internet access without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless connection is established between mobile device and vehicle information system, then infotainment functions and Internet access are enabled, but active pairing is required which increases user effort and complexity
Solution Approach 1:
The system performs preliminary actions by storing communication parameters (MAC addresses, pairing information) in a database before the actual connection is needed. When a mobile device approaches the vehicle, the system automatically retrieves pre-stored parameters and initiates connection without requiring user pairing actions, thus resolving the contradiction between enabling infotainment functions and reducing connection setup effort
Solution Approach 2:
The connection establishment process is made self-service by implementing automated pairing mechanisms. The system uses stored communication parameters to automatically authenticate and connect mobile devices without user intervention, eliminating the need for manual pairing while maintaining secure access to infotainment functions and Internet connectivity
2Ease of operation
If automated pairing is implemented using stored communication parameters, then user effort is reduced, but system complexity increases due to database and parameter management requirements
Solution Approach 1:
A database acts as an intermediary component that manages communication parameters between the vehicle's information system and mobile devices. This intermediary handles the complexity of parameter storage, retrieval, and management internally, while presenting a simplified automated pairing interface to users, thus resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The database system serves multiple functions: storing MAC addresses, managing pairing information, enabling automated connection, and supporting multiple mobile devices. By consolidating these functions into a single multi-functional module, the system manages complexity internally while providing simplified automated pairing to users

AI summary
Apparatuses, methods and computer programs for establishing a communication link between an information system and a mobile device. The apparatus for an information system includes a first communication module for communication with a computer infrastructure, a second communication module for communication with the mobile device, and a control module for controlling the first communication module and the second communication module. The control module obtains information about communication parameters for a communication link between the information system and the mobile device from the mobile device using the computer infrastructure and the first communication module and establishes the communication link between the information system and the mobile device using the second communication module based on the information about the communication parameters.
