Communication Terminal Background Image Sharing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication terminals cannot obtain or share a background image from a server during a handwriting chat with another terminal.
Innovation Solution
A communication terminal with a display, input device, and control unit that receives a background image from a server and transmits it to another terminal for overlapped display, allowing users to draw and share handwriting images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication terminal performs handwriting chat with another terminal using conventional methods, then the handwriting chat function is available, but a background image cannot be obtained from or shared with another terminal
Solution Approach 1:
The patent separates the background image management into distinct components: acquisition from server, local storage, and transmission to another terminal. This segmentation allows each function to be independently implemented and optimized, enabling background image sharing without disrupting existing handwriting chat functionality.
Solution Approach 2:
The communication terminal acts as an intermediary between the server and another terminal for background image transfer. The terminal acquires the background image from the server, stores it locally, and then transmits it to the other terminal, enabling background image sharing without requiring direct server-terminal connection for this specific function.
2Adaptability or versatility
If a communication terminal transmits multiple types of data (handwriting image data and background image data), then the communication functionality is enhanced, but the data management complexity increases
Solution Approach 1:
The patent implements dynamic data type identification and routing within the communication terminal. The system automatically determines whether incoming data is handwriting image data or background image data based on data type indicators, and dynamically routes it to the appropriate processing and storage location, managing complexity through adaptive control rather than fixed rigid structures.
Solution Approach 2:
The patent applies different processing and storage methods to different data types based on their specific requirements. Handwriting image data is processed for immediate display and transmission, while background image data is stored for later use in chat sessions. Each data type receives specialized handling optimized for its particular characteristics and usage pattern.

AI summary
A communication terminal includes: a display, an input device for accepting a first operation instruction; a communication device for connection with a server and another terminal; and a control unit for receiving first contents from the server via the communication device according to the first operation instruction, determining whether connection with another terminal is established or not, transmitting the first contents to another terminal via the communication device when a determination is made that connection with another terminal is established, and causing the display to show the first contents.
