Wireless Data Transfer System with Dynamic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer methods via wireless communication require complex user operations and do not allow users to selectively transfer image data files, leading to poor usability.
Innovation Solution
A data communication system that uses short-range wireless transfer techniques to enable users to select and transfer image data files by controlling the connection and disconnection of wireless communication between devices, allowing for simple operation and selection of next or previous image files based on connection status and timer settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic transfer of multiple image data files is performed upon establishment of wireless communication, then usability for the user is improved by reducing operations, but the user cannot select image data files to be transferred
Solution Approach 1:
The patent implements dynamic switching between two transfer modes: automatic transfer mode (for simplicity) and selective transfer mode (for user control). The system dynamically adapts its behavior based on user input received after wireless communication establishment, allowing the transfer mechanism to transition from fully automatic to user-selective operation.
Solution Approach 2:
The patent performs preliminary establishment of wireless communication and preliminary display of thumbnail images before the actual data transfer begins. This preliminary action allows users to preview available image files and make informed selection decisions before the transfer process starts, combining automation with user control.
2Device complexity
If all image data files are transferred automatically upon wireless communication establishment, then the transfer process is simplified, but the user loses control over which files are transferred
Solution Approach 1:
The patent implements a feedback mechanism where thumbnail images of stored image data files are displayed to the user after wireless communication is established. This feedback allows users to see what files are available for transfer and make informed decisions about which files to select, creating a loop between system action and user response.
Solution Approach 2:
Instead of transferring all image files automatically (excessive action) or requiring full manual selection (complete complexity), the patent implements partial action by allowing users to select specific files from a displayed list. This partial selection approach reduces complexity while maintaining user control for those who need it.
3Speed
If short-range wireless transfer techniques are used for data transfer, then communication range is limited, but transfer speed and simplicity are improved
Solution Approach 1:
The patent implements automatic connection establishment and automatic thumbnail display functionality that operates without user intervention. Once devices are brought into proximity, the system automatically establishes wireless communication, retrieves available image files, and displays thumbnails for user selection, making the system self-serve the user throughout the process.
Data Source
AI summary
A data supplying apparatus detects a change in the status of the wireless connection established with an external apparatus. When the status of the wireless connection is restored after a change has been detected in the status of the wireless connection, the data supplying apparatus transmits, to the external apparatus, a different data file from the previous data file transmitted by the wireless connection before restoration of the connection.
