Display Control Unit for Offline Content Update Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems fail to notify users of update information when they are unable to acquire data from a server, leading to incomplete user awareness of available content updates.
Innovation Solution
An information processing apparatus with an acquisition unit to manage update periods, a storage control unit to store management information, and a display control unit to indicate content updates within specified periods, ensuring users are notified of updates even without a network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the application continuously monitors the server for update information, then the user can be notified of updates in real-time, but the system consumes excessive energy and network resources
Solution Approach 1:
The application performs update checking at predetermined intervals rather than continuously monitoring. The server sends update information at specific timing, and the application checks for updates periodically, reducing energy consumption while maintaining reliable update notification
Solution Approach 2:
The server prepares update information in advance and sends it to the terminal at predetermined timing before the user needs it. This preliminary action allows the terminal to have update information ready without continuous monitoring, reducing energy consumption
2Reliability
If the application checks for updates frequently, then the user is notified of updates quickly, but the network bandwidth is consumed excessively
Solution Approach 1:
Both the server and terminal perform update checking at predetermined intervals. The server sends update information at specific timing, and the terminal checks at corresponding intervals, reducing network bandwidth consumption while maintaining timely update notification
Solution Approach 2:
The update checking mechanism operates continuously at predetermined intervals, ensuring that update information is always available when needed while optimizing network bandwidth usage through scheduled communications
3Loss of information
If the application displays update marks continuously, then the user is always aware of available updates, but the display becomes cluttered and user experience deteriorates
Solution Approach 1:
The update mark is displayed selectively based on local conditions - it appears only when update information is actually available and is hidden when no updates are present. This localized display approach maintains information visibility while preserving interface clarity
Solution Approach 2:
The update mark changes its display state based on update availability - it is displayed when updates are available and hidden or changed when no updates exist. This dynamic display behavior maintains user awareness without creating permanent visual clutter

AI summary
An information processing apparatus includes an acquisition unit, a storage control unit, and a display control unit. The acquisition unit acquires management information for managing a period during which a content update is displayed. The storage control unit controls a memory to store the acquired management information. The display control unit controls a display unit to display an object for selecting a content. When displaying the object, the display unit performs a display indicating an update of the content within a period managed by the management information, and does not perform the display indicating an update of the content out of the period managed by the management information, based on the stored management information. When displaying the content, the display control unit controls the display unit to display information indicating an update of the content within the period managed by the management information, even when the object is selected.
