Mobile Terminal Content Extraction via Log-Based Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in simultaneously viewing contents generated from multiple applications on a mobile terminal for a preset period of time.
Innovation Solution
A mobile terminal with a memory to store contents and log information, a user input unit for receiving condition information, and a controller to extract and display contents based on this information, including application type, format, date, location, and counterparty information, allowing for organized display and arrangement of contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contents from multiple applications are stored and displayed together, then user convenience and content organization are improved, but device complexity and data management complexity increase
Solution Approach 1:
The patent segments content management by application type, storing contents from different applications (messaging, browsing, media playback) in separate categories within the memory. The controller retrieves and displays contents based on selected application types, dividing the complex multi-application data into manageable segments that can be independently organized and accessed.
Solution Approach 2:
The controller acts as an intermediary between the stored contents and the display unit. It manages the complex data retrieval process by receiving user input specifying conditions (application type, time period, content format), extracting relevant contents from memory based on these conditions, and presenting them in an organized manner on the display, thereby simplifying the interaction between user and complex data storage system.
2Productivity
If contents are extracted and displayed based on multiple condition information, then content organization and accessibility are improved, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary organization of contents by application type and metadata characteristics when contents are initially stored in memory. This pre-categorization allows the controller to quickly retrieve relevant contents by simply selecting the corresponding application type and time period, avoiding the need to process and filter all contents from scratch each time a display request is made.
Solution Approach 2:
The patent applies different retrieval strategies based on the specific conditions requested. When a user selects a particular application type and time period, the controller optimizes the retrieval process by focusing only on the relevant segment of stored data with matching characteristics, rather than processing the entire data set uniformly.
3Measurement precision
If multiple condition information parameters are stored with each content, then content retrieval accuracy and organization are improved, but memory usage and data storage complexity increase
Solution Approach 1:
The patent extracts and stores only the essential metadata parameters needed for content retrieval and organization, such as application type, content format, and time period information. By selecting and storing only these critical identifying characteristics rather than all possible content attributes, the system achieves accurate content retrieval while minimizing the additional memory consumption associated with metadata storage.
