Electronic Device Standby Mode Wake-Up Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modular display systems, it is inconvenient to manually switch both the electronic device and the display device from a standby mode to a normal mode, as control signals cannot be automatically transmitted between them when they are in standby mode, leading to synchronization issues during power-on operations.
Innovation Solution
An electronic device with a communication interface and processor is configured to transmit pulse signals and control signals to corresponding display modules, allowing automatic switching from standby to normal mode upon receiving a remote control signal, ensuring both devices can synchronize their power states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the electronic device and display device are in standby mode to save energy, then power consumption is reduced, but control signals cannot be transmitted between devices leading to manual switching requirements
Solution Approach 1:
The electronic device performs preliminary actions by transmitting a wake-up signal to activate the display device's communication module before transmitting the control signal. This preliminary activation enables automatic control signal transmission without requiring manual user intervention, resolving the contradiction between energy saving in standby mode and ease of operation during mode switching.
2Reliability
If control signals are transmitted to each device individually from standby mode, then both devices can be switched to normal mode, but the process becomes complex and time-consuming
Solution Approach 1:
The patent merges the control signal transmission process by enabling the electronic device to automatically transmit control signals to the display device after receiving a mode switching command. This combining of functions allows both devices to be switched to normal mode through a single user input, reducing switching time while ensuring complete device activation.
3Loss of energy
If the communication module remains off in standby mode to save power, then energy consumption is reduced, but automatic control signal transmission cannot occur
Solution Approach 1:
The system performs preliminary action by sending a wake-up signal that temporarily activates the display device's communication module just long enough to receive the control signal. This approach maintains the communication module in an off state during normal standby operation (saving energy) while enabling automatic control signal transmission when needed (maintaining automation).
Solution Approach 2:
The communication module operates in a periodic manner, switching between off state during standby (energy saving) and on state when wake-up signals are received (automation enabled). This periodic activation pattern resolves the contradiction by allowing the module to be off most of the time while still providing automatic functionality when required.
