Mobile Terminal File Management System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in efficiently managing and storing various forms of data generated by their complex functions, requiring large memory capacity and often necessitating additional automation devices or data cables for effective data management.
Innovation Solution
A mobile terminal with a data management unit that allows for easy management of files and folders using a simple storage structure, enabling users to access and store data without predefining application software, and configuring storage regions both internally and externally for maximum memory efficiency, including a method for performing search functions and data storage based on user settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile terminals are equipped with various functions (digital camera, video playback, wireless Internet), then data generation and storage requirements increase, but memory capacity and management complexity increase
Solution Approach 1:
The patent divides the storage system into multiple memory devices (internal memory and external memory cards) and organizes data into folders and files. This segmentation allows the terminal to manage large amounts of data generated by various functions without requiring a single large memory block, thus reducing management complexity while maintaining high storage capacity.
Solution Approach 2:
The patent introduces a hierarchical directory structure (folders within folders) and implements a file management system with multiple access dimensions. This allows data to be organized and accessed through multiple pathways (by type, by date, by location), effectively increasing storage capacity without adding physical memory.
2Quantity of substance
If a large number of files and folders are stored in memory, then data storage capacity increases, but working memory usage and processing complexity increase
Solution Approach 1:
The patent extracts only the necessary file information (names and paths) into the working memory when displaying or accessing files, rather than loading entire file contents or complete directory structures. This extraction approach minimizes working memory usage while maintaining full access to stored data through the file management system.
Solution Approach 2:
The patent pre-organizes data into folders and establishes a hierarchical directory structure before data access occurs. This preliminary organization allows the file management unit to quickly locate and access files without complex real-time processing, reducing working memory requirements during data retrieval operations.
3Quantity of substance
If traditional file management systems are used, then data can be stored, but additional devices (PCs, data cables) are required for effective data management
Solution Approach 1:
The patent implements a self-contained file management system within the mobile terminal that includes a file management unit capable of creating, deleting, moving, and copying files and folders. This self-service capability allows users to manage their data directly on the terminal without requiring external devices like PCs or data cables, significantly improving data management convenience.
4Loss of energy
If minimal working memory is used to display file names, then memory efficiency increases, but the ability to manage and access data efficiently decreases
Solution Approach 1:
The patent introduces a file management unit that acts as an intermediary between the stored files and the display unit. This intermediary maintains a simplified index in working memory containing only file names and paths, while providing full file management capabilities through systematic organization. The intermediary structure allows efficient data access with minimal working memory by translating user requests into precise file location queries.
Data Source
AI summary
A mobile terminal having a function of managing files and folders is disclosed. In one embodiment, the mobile terminal displays folder items representing one or more memory elements installed in or joined to the mobile terminal on a display unit when a request to perform a search function is inputted, and displays selection items corresponding to at least one of files included in the folder item and subfolders on the display unit when a select command for a folder item is inputted. At least one embodiment of the invention allows easy management of data (e.g., files, folders, etc.) stored in one or more memory devices installed in or joined to the mobile terminal.
