Electronic Device Power State Management via Image Data Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When two devices are connected for cooperative work, the lack of awareness of the actual operating state of one device by the other can lead to abnormal power failures, resulting in issues like a blue screen when the device is turned on next time.
Innovation Solution
A control method and device that allow a first electronic device to output image data from a second electronic device, using a control instruction to switch from a high-power state to a lower power state, thereby avoiding abnormal power failures and improving operational stability.

Engineering Contradiction Analysis
1Use of energy by stationary object
If the first electronic device powers off the second electronic device without knowing its actual operating state, then the power consumption is reduced, but abnormal power failures and blue screens occur
Solution Approach 1:
The first electronic device queries the second electronic device to obtain its actual operating state before powering it off. This feedback mechanism ensures the first device knows whether the second device is in a sleep state or completely powered off, preventing abnormal power failures while still enabling energy-saving operations.
Solution Approach 2:
The first electronic device performs a state query before executing the power-off operation. This preliminary action of obtaining the operating state information allows the system to make informed decisions about whether to actually power off the second device, avoiding premature or inappropriate power-off actions that could cause blue screens.
2Reliability
If the first electronic device continuously monitors the second device's state, then operational stability is improved, but power consumption increases
Solution Approach 1:
Instead of continuous monitoring, the first electronic device periodically queries the second device's operating state at specific moments before power-off operations. This periodic action maintains sufficient awareness of the second device's state to prevent abnormal power failures while significantly reducing overall power consumption compared to continuous monitoring.

AI summary
A control method includes: outputting first image data of a first electronic device, obtaining a first control instruction, and switching to outputting second image data of a second electronic device. The first control instruction is used to control the first electronic device to switch from a first state to a second state. The power consumption of the first electronic device in the first state being greater than the power consumption in the second state. The second electronic device is communicatively connected with the first electronic device.
