Mobile Terminal Remote Control via Key Code Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack the ability to be remotely controlled when connected to external devices, requiring users to physically interact with the terminal for operations like volume adjustment and channel conversion, which is inconvenient, especially when viewing multimedia data at a remote location.
Innovation Solution
A mobile terminal and method that enable remote control using a preset key code transmitted from a remote control device, converting the key code into operation codes to control data output operations, allowing users to control multimedia data reproduction through external devices from a distance via local area wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the mobile terminal is connected to an external device to output multimedia data, then the display quality and audio output are improved, but the user cannot control the terminal operations from a remote location
Solution Approach 1:
The patent introduces a remote control device as an intermediary between the user and the mobile terminal. The remote control device transmits control signals to the mobile terminal, enabling the user to control terminal operations from a remote location without needing to physically interact with the terminal device.
Solution Approach 2:
The control function is segmented from the mobile terminal and transferred to a separate remote control device. This allows the control operations to be performed remotely while the mobile terminal continues to handle multimedia output through the external device connection.
2Use of energy by moving object
If the display unit is turned off to save power when connected to an external device, then energy consumption is reduced, but the user cannot perform key manipulation for controlling operations
Solution Approach 1:
The remote control device serves as a mediator that enables control operations without requiring the display unit to be active. Users can send control commands through the remote control device even when the terminal's display is turned off to save power.
Solution Approach 2:
The system allows control operations to be performed through the remote control device without requiring the terminal's display or local interface to be active, enabling power-saving mode while maintaining operational capability.
3Volume of moving object
If the mobile terminal uses a limited-size display unit and speaker for multimedia output, then portability and manufacturing cost are improved, but the multimedia output quality is limited
Solution Approach 1:
The patent extracts the high-quality display and audio output functions from the mobile terminal and relocates them to external devices. The mobile terminal retains only the essential portable form factor while leveraging external devices for enhanced multimedia output quality.
Solution Approach 2:
The mobile terminal is designed to work with various external devices (TVs, monitors, speakers) to provide enhanced multimedia output. This multi-functionality approach allows the terminal to maintain portability while achieving high-quality output through different external configurations.
4Device complexity
If the mobile terminal requires physical interaction for control operations when connected to external devices, then device complexity is reduced, but user convenience for remote viewing is worsened
Solution Approach 1:
The remote control device acts as an intermediary that bridges the gap between the user and the mobile terminal. It transmits control signals wirelessly or through infrared communication, enabling convenient remote control without adding complexity to the terminal's physical interface.
