Portable Terminal Chatting Screen External Apparatus Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional messenger programs do not allow users to share services or control external apparatuses, such as televisions, between portable terminals.
Innovation Solution
A method and system for a portable terminal to display icons of external apparatuses on a chatting screen, allowing users to select and control these apparatuses by transmitting information and control commands between terminals via a server, enabling shared experiences with other users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional messenger programs are used for chatting, then users can share text information and files, but users cannot control external apparatuses or share services between portable terminals
Solution Approach 1:
The messenger program is enhanced to perform multiple functions beyond basic text and file sharing. It now includes external apparatus control capabilities, service sharing, and coordination between multiple portable terminals, allowing a single application to handle diverse communication and control tasks
Solution Approach 2:
A server acts as an intermediary between portable terminals to enable external apparatus control. The server receives control requests from one terminal, transmits them to the target terminal or apparatus, and facilitates coordinated control of external devices like televisions, allowing users to share and control apparatuses remotely
2Adaptability or versatility
If external apparatus control is added to messenger programs, then service sharing is enabled, but system complexity increases
Solution Approach 1:
The server serves as an intermediary that handles the complexity of external apparatus control protocols, device discovery, and coordination logic. This externalizes the complex processing from the portable terminal applications, keeping the client-side software relatively simple while enabling sophisticated control capabilities through server-mediated interactions
3Adaptability or versatility
If multiple portable terminals need to control the same external apparatus, then service sharing is improved, but control coordination becomes more difficult
Solution Approach 1:
The server implements feedback mechanisms to track which terminal is currently controlling an external apparatus and what state the apparatus is in. This feedback information is transmitted to all participating terminals, allowing users to see real-time control status and avoid conflicts, making multi-terminal control coordination transparent and manageable
Solution Approach 2:
The server mediates control requests between multiple terminals and the external apparatus. It receives control commands from any terminal, manages the control state, and ensures proper routing and coordination, eliminating the need for complex peer-to-peer negotiation between terminals and simplifying multi-user control operations
