Vehicle Mobile Data Sharing Control via Residual Data Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles without a Wi-Fi access point, existing methods for sharing mobile data between smartphones require manual checking and setting, which can distract drivers and increase the risk of accidents, especially when multiple users need to share data.
Innovation Solution
A control method that automatically determines the priority of terminals based on residual data to assign a host and client terminal, providing access information for seamless data sharing without manual intervention, using a communicator to request and receive terminal information, and a controller to manage the connection and display access details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual checking and setting of data sharing is performed, then data sharing can be configured, but driver distraction and accident risk increase
Solution Approach 1:
The system automatically performs data sharing configuration without requiring manual user intervention. The controller autonomously selects host and client terminals based on residual data amounts, establishes connections, and manages data sharing processes, thereby eliminating driver distraction while maintaining ease of operation
Solution Approach 2:
The system pre-configures data sharing settings before the driver needs to use the vehicle. Terminal information is collected and processed in advance, and connection settings are prepared automatically, so that when data sharing is needed, the system is already configured and ready to operate
2Object-affected harmful factors
If automatic priority determination is implemented, then driver distraction is reduced, but system complexity increases
Solution Approach 1:
The controller acts as an intermediary between multiple terminals, collecting terminal information, determining priorities based on residual data, and managing connections automatically. This intermediary approach centralizes complexity in a dedicated component while presenting a simple automatic interface to users
Solution Approach 2:
The system continuously monitors residual data amounts of terminals and uses this feedback to dynamically determine priorities and select host/client roles. This feedback mechanism enables automatic adaptation without requiring complex manual configuration, balancing system intelligence with operational simplicity
3Adaptability or versatility
If manual setting changes are required, then data sharing can be controlled, but time consumption increases
Solution Approach 1:
The system automatically determines which terminal becomes host and which becomes client based on real-time residual data amounts. This self-service approach eliminates the need for users to manually select roles or configure settings, reducing configuration time while maintaining adaptable control over data sharing
Solution Approach 2:
The system uses residual data amounts as a dynamic parameter to automatically determine terminal roles. By changing the selection criterion from manual input to automated parameter-based decision-making, the system achieves both speed and adaptability in data sharing configuration

AI summary
A method of controlling mobile data sharing, performed by a computing device, may include transmitting a signal to request terminal information for sharing data to a plurality of terminals and receiving the terminal information from the plurality of terminals, determining an order of priority to assign a status of a host terminal and a status of a client terminal using the terminal information, and providing access information for connecting the client terminal to the host terminal on the basis of the determined order of priority.
