Mobile File Transfer via Automatic Cloud Download Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional file exchange systems require additional operations when transferring files stored on an online storage to another mobile device, as users must first download the file to their device before transmitting it, increasing the number of steps compared to direct mobile device-to-mobile device transfers.
Innovation Solution
A mobile device system that acquires file information from a network server, determines if the file is stored internally, and either transmits it directly if present or downloads it from the server if not, allowing unified file exchange operations regardless of storage location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the file exchange system downloads files from online storage to mobile device before transmission, then files can be transmitted from network storage, but the number of operations increases and operational complexity increases
Solution Approach 1:
The patent merges the file download function and file transmission function into a single integrated operation. When a user selects a file from the online storage list, the system automatically downloads the file to the mobile device and then transmits it to the target device in one continuous process, eliminating the need for separate download and transmit steps.
Solution Approach 2:
The mobile device acts as an intermediary between the online storage server and the target mobile device. It temporarily receives the file from the server, processes it locally, and then forwards it to the destination, enabling seamless file exchange without requiring the user to manually manage the file's location or perform multiple distinct operations.
2Loss of information
If the system requires separate operations for local and network files, then file storage location can be tracked, but operational complexity increases
Solution Approach 1:
The file exchange interface is designed to handle both locally stored files and files from online storage through a unified operation mode. The system automatically detects the file's storage location and adapts the transmission process accordingly, presenting the same user interface and interaction method regardless of whether the source is local or network-based.
Solution Approach 2:
The system automatically determines the file's storage location and selects the appropriate transmission method without requiring user input. When a file is selected from the online storage list, the system self-manages the download and transmission process, eliminating the need for users to distinguish between local and network files or choose different operation modes.
Data Source
AI summary
A mobile device includes a file information acquiring unit, a file information display unit that displays the file information acquired on a display unit, a file presence identifying unit that determines whether or not a file specified by file information designated by a user from among the file information displayed on the display unit is stored in a storage unit, a first file transmitting unit that transmits the stored file to another mobile device when the file presence identifying unit determines that the file is stored in the internal storage unit, a file acquiring unit that downloads the file specified by the designated file information from the server when the file presence identifying unit determines that the file is not stored in the internal storage unit, and a second file transmitting unit that transmits the file acquired by the file acquiring unit to the other mobile device.
