Mobile Data Sharing via Remote Server Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless connection technologies between mobile devices, such as Bluetooth and Wi-Fi Direct, are unstable and inefficient for transferring large amounts of data, especially when devices have different operating systems or limited peer-to-peer communication capabilities.
Innovation Solution
A method and system that enable mobile devices to establish wireless connections directly with each other using technologies like Wi-Fi Direct and Bluetooth Low Energy (BLE), allowing data sharing without user input, and utilizing a remote server to retrieve additional information about entities identified through exchanged data, even if the devices have different operating systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth or Wi-Fi Direct is used for direct wireless connection between mobile devices, then data sharing is enabled without requiring user input, but the connection stability deteriorates and data transfer reliability decreases
Solution Approach 1:
The patent introduces a remote server as an intermediary to mediate data transfer between mobile devices. Instead of relying solely on unstable direct peer-to-peer connections, the server acts as a reliable intermediate node that receives data from one device and forwards it to the target device, thereby ensuring data transfer reliability while maintaining automatic operation.
Solution Approach 2:
The patent segments the data transfer process into multiple stages: initial device discovery and connection establishment using Bluetooth/Wi-Fi Direct, followed by data retrieval from remote servers using stable Internet connections, and final data delivery. This segmentation allows each stage to use the most appropriate communication method for its specific requirements.
2Productivity
If direct wireless connection is established between mobile devices for data transfer, then data sharing speed is improved, but connection loss frequency increases
Solution Approach 1:
The remote server serves as a stable intermediary that maintains persistent connections with devices. Rather than requiring continuous direct connections between devices (which are prone to loss), the server maintains stable connections and manages data routing, thereby reducing connection loss frequency while enabling efficient data transfer.
Solution Approach 2:
The system performs preliminary actions by establishing connections and retrieving data from remote servers before actual peer-to-peer data transfer is needed. This preliminary data preparation reduces the burden on direct device connections and minimizes their exposure to connection loss risks.
3Use of energy by moving object
If Bluetooth Low Energy is used for initial connection establishment, then power consumption is reduced, but data transfer capacity is limited
Solution Approach 1:
The patent segments data transfer into two phases: Phase 1 uses Bluetooth Low Energy for low-power device discovery, connection establishment, and transmitting only essential small amounts of data (device identifiers, basic information). Phase 2 uses high-capacity Internet connections for retrieving and transferring large data volumes from remote servers. This segmentation enables the system to benefit from both low power consumption and high data transfer capacity.
Solution Approach 2:
The remote server acts as an intermediary that handles the bulk data storage and transfer. Mobile devices use low-power Bluetooth only for initial contact, then delegate large data transfers to the server via high-capacity Internet connections, thereby avoiding the need for sustained high-power direct device-to-device connections.

AI summary
Techniques are provided for sharing data among computing devices. In one technique, a first device broadcasts wireless data and establishes a wireless connection with a second device. The first device receives authorization data and first entity data from the second device. The first device authorizes the second device based on the authorization data. The first device then sends second entity data through the wireless connection to the second computing device. The first device sends the first entity data over a network to a remote server system. The first device receives, from the remote server system, entity data that pertains to an entity that is identified by the first entity data. The first device may then display at least a portion of the entity data on a screen of the first device.
