Remote Screen Control via Intermediary Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when frequently turning the screen on/off on mobile devices, such as selfie sticks, while using them for photography, as they need to manually press the power button, especially in situations like traveling.
Innovation Solution
A method and apparatus that allow a first terminal to control a second terminal to turn its screen on/off directly, using a preset condition, such as a button press duration, to determine the current screen state and adjust it accordingly, enabling the second terminal to unlock or lock the screen based on the operation instruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually press the power button to turn the screen on/off, then the screen can be controlled, but the operation becomes troublesome and inconvenient
Solution Approach 1:
The patent introduces a remote control device as an intermediary between the user and the terminal screen. The remote control receives instructions from the user and transmits them to the terminal to control screen on/off states, eliminating the need for direct manual operation of the power button and providing more convenient control especially when the terminal is held in one hand for photography
2Ease of operation
If the screen remains on during frequent use, then operation is convenient, but energy consumption increases
Solution Approach 1:
The patent implements dynamic screen state management where the screen automatically adjusts its on/off state based on real-time operational context. The system monitors whether the terminal is currently being used for photography or other tasks, and dynamically switches the screen state accordingly - keeping it on during active use and turning it off during idle periods to optimize energy consumption
3Loss of energy
If the screen is turned off to save energy, then power consumption decreases, but user data security is compromised
Solution Approach 1:
The patent employs feedback mechanisms where the system continuously monitors operational status and automatically adjusts screen state in response. When the terminal detects that it has been idle for a predetermined period or that photography operations have completed, it automatically turns off the screen to save energy. Conversely, when new operations are detected, the screen is automatically turned back on, thus balancing energy savings with security requirements without user intervention

AI summary
A terminal screen-on/off control method includes receiving an operation instruction that is sent by a user by using a first terminal; if the operation instruction meets a preset condition, determining a current state of a screen of a second terminal, and if the current state of the screen is on, controlling the second terminal to turn off the screen; or if the current state of the screen is off, controlling the second terminal to turn on the screen. The preset condition is used to determine whether the second terminal is to turn the screen on/off. The first terminal can be directly used to control the second terminal to turn the screen on/off. This operation is very simple.
