Server-Mediated Data Editing System for Network File Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information management systems require direct physical connections between terminal devices for data editing and sharing, limiting usability and convenience, especially when editing and sharing document files like PDFs.
Innovation Solution
An information management system comprising a first terminal device with a communication unit to acquire data from a server, an operation unit for editing, and a controller to transmit edit data back to the server, and a server device with a communication unit to store and manage edited data, allowing seamless editing and sharing of files across connected devices via a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is downloaded to a terminal device for editing, then editing capability is improved, but connection requirements (short-range wireless or wired cable) reduce usability
Solution Approach 1:
The patent introduces a server as an intermediary between terminal devices, enabling data sharing and editing without direct physical connections. The server stores original data and edited versions, mediating the interaction between multiple terminal devices through network connections, thus eliminating the need for short-range wireless or wired cables between devices.
Solution Approach 2:
The patent replaces mechanical connection systems (wired cables and short-range wireless connections) with a network-based system. Instead of requiring physical or proximity connections between terminal devices, the system uses network communication to transmit data and editing operations, substituting mechanical interaction with electronic data exchange.
2Adaptability or versatility
If multiple terminal devices are connected for data sharing, then data accessibility is improved, but connection complexity increases
Solution Approach 1:
The patent makes the server a universal access point for all terminal devices. Instead of requiring pairwise connections between devices, any terminal device can connect to the server to access and edit data. The server provides multi-functional services including data storage, editing operation reception, and result distribution, enabling versatile data accessibility without increasing connection complexity.
3Ease of manufacture
If edited data is stored locally on terminal devices, then editing functionality is improved, but data synchronization and sharing become difficult
Solution Approach 1:
The patent implements a feedback mechanism where editing operations performed on terminal devices are transmitted to the server, which stores the edited data. The server then provides feedback by making the edited data available to other terminal devices. This feedback loop ensures that all devices access the same updated version of the data, maintaining synchronization without requiring local storage of edited versions on each device.
Data Source
AI summary
An information management system includes a first terminal device, and a server device, wherein the first terminal device includes a wireless communication I/F that acquires first data from the server device, a touch panel that receives an operation, and a first controller that transmits, when the touch panel receives an editing operation on the acquired first data, edit data corresponding to the editing operation to the server device, and wherein the server device includes a server communication I/F that acquires the edit data from the first terminal device, a server storage unit that stores the first data and the edit data in association with each other, and a server controller that provides a user with second data obtained by editing the first data stored in the server storage unit in accordance with the edit data.
