Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face challenges in cost-effective wake-up mechanisms, with complex control systems that increase costs and reduce efficiency when transitioning from standby, suspended, or sleep modes to active states.
Innovation Solution
A method and apparatus that utilize a wake-up packet to control internal circuits of electronic devices, where a processing circuit detects user input and sends a wake-up packet to another device's wake-up service circuit, allowing it to resume from suspension, using a simplified mechanism that reduces complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional control mechanisms are used to wake up electronic devices from standby or sleep modes, then the devices can be activated, but the control mechanism complexity increases and costs increase
Solution Approach 1:
The patent extracts the wake-up control function into a separate, dedicated wake-up service circuit that operates independently from the main processor. This wake-up circuit monitors for wake-up events and packets separately, allowing the main processor to remain in low-power mode while still enabling reliable wake-up control through the dedicated circuit.
Solution Approach 2:
The patent introduces a wake-up packet as an intermediary signal that mediates between the external environment and the electronic device's internal state. The packet contains specific wake-up information that the wake-up service circuit detects to trigger device activation, simplifying the control mechanism by using a standardized intermediate signal format.
2Reliability
If conventional control mechanisms are used to wake up electronic devices, then devices can be activated, but associated costs increase
Solution Approach 1:
By extracting the wake-up control function into a dedicated circuit with specific wake-up information detection capabilities, the patent enables cost-effective implementation using simpler, more specialized components rather than requiring complex general-purpose control mechanisms.
Solution Approach 2:
The wake-up packet serves as a simple, lightweight signaling mechanism that can be implemented with minimal hardware resources. The use of standardized packet formats and dedicated wake-up circuits reduces manufacturing costs compared to complex proprietary wake-up systems.
3Use of energy by moving object
If processors and associated circuits are controlled to be inactive to save battery power, then energy consumption decreases, but the wake-up mechanism becomes complex
Solution Approach 1:
The patent segments the device's operational states and control mechanisms into distinct functional blocks: a low-power main processor, an independent wake-up service circuit, and a standardized wake-up packet system. This segmentation allows the processor to remain fully inactive during standby modes while the simplified wake-up circuit handles activation, reducing overall system complexity.
Solution Approach 2:
The wake-up packet acts as an intermediary that enables communication between the external environment and the inactive processor without requiring the processor to remain active. The dedicated wake-up service circuit interprets these packets and triggers processor activation only when necessary, maintaining energy efficiency while simplifying the wake-up mechanism.

AI summary
A method and apparatus for performing wake-up control are provided, where the method is applied to an electronic device, and the method may include the steps of: detecting whether a predetermined wake-up action is input into the electronic device, wherein the predetermined wake-up action is a user action for wake-up control; and when it is detected that the predetermined wake-up action is input into the electronic device, sending a wake-up packet carrying predetermined wake-up information to allow an internal circuit of another electronic device to be woken up in response to detection of the predetermined wake-up information.
