Portable Terminal Controlling External Devices Without Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smartphone technologies do not allow for effective control of external devices such as TVs or displays, limiting users to mere data output without the ability to control or update these devices easily.
Innovation Solution
A portable terminal apparatus and method that recognizes and controls external devices by extracting setting data from its memory, allowing it to function as both a controller and memory for connected external devices, enabling users to access extended functions and services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a portable terminal is used to output data to external devices, then data transmission capability is improved, but control capability over external devices deteriorates
Solution Approach 1:
The portable terminal is designed to perform multiple functions: it serves as both a data output device and a control device for external devices. The terminal includes a controller that can detect external device types and extract corresponding setting data, enabling it to control various external devices (TVs, displays, audio devices) without requiring separate control mechanisms for each device type.
2Adaptability or versatility
If external devices are equipped with their own controllers and memory, then device functionality is improved, but system complexity and cost increase
Solution Approach 1:
The patent merges the controller and memory functions into the portable terminal rather than having separate controllers and memory in each external device. The terminal's controller detects external device types and extracts appropriate setting data from the terminal's memory, consolidating control functionality into a single device and reducing overall system complexity.
Solution Approach 2:
The portable terminal acts as an intermediary between the user and external devices. Instead of users directly controlling external devices or each device having its own control system, the terminal mediates by detecting device types, extracting appropriate setting data, and controlling external devices based on that data.
3Adaptability or versatility
If multiple external devices are supported, then system versatility is improved, but difficulty in detecting and measuring device types increases
Solution Approach 1:
The patent stores setting data for multiple external device types in advance in the portable terminal's memory. When an external device is connected, the controller detects the device type and retrieves the pre-stored setting data corresponding to that device type, eliminating the need for complex real-time analysis or measurement of device characteristics.

AI summary
Provided is a terminal for controlling an external device, not equipped with its own memory or controller, connected to the terminal. The portable terminal, when being connected to at least one external device, changes its setting with an extracted setting data matching the connected external device. Accordingly, the connected external device in a connection state to the portable terminal performs corresponding operations under control of the portable terminal.
