Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer power saving methods often incorrectly determine user absence, leading to inefficient power consumption and inconvenient waking from power-saving mode, as they rely on inactivity of input interfaces rather than user presence.
Innovation Solution
A computer power saving and waking method utilizing a Bluetooth signal receiving port to determine user presence by monitoring the intensity of communication signals from registered mobile devices, switching between working and power-saving modes based on signal strength, ensuring precise detection of user absence for efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the computer switches to power-saving mode based on input interface inactivity, then power consumption is reduced, but user presence detection accuracy deteriorates
Solution Approach 1:
The patent introduces Bluetooth technology as an intermediary detection mechanism. Instead of relying solely on input interface activity, the system uses Bluetooth signal presence from registered mobile devices as a mediator to accurately detect user presence. This allows the computer to maintain power-saving mode when no Bluetooth signals are detected while avoiding false transitions when the user is merely not using input devices but still present.
2Device complexity
If the computer requires manual operation to wake from power-saving mode, then power management control is simplified, but user convenience deteriorates
Solution Approach 1:
The patent implements self-service wake-up functionality where the computer automatically transitions from power-saving mode to working mode when it detects Bluetooth signals from registered mobile devices. The system serves itself by using the presence detection mechanism to trigger automatic mode switching, eliminating the need for manual user intervention while maintaining simple power management logic.
3Device complexity
If the computer uses traditional inactivity-based power saving, then implementation simplicity is maintained, but power saving efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the power mode transition conditional and adaptive rather than static. The system dynamically adjusts between working mode and power-saving mode based on real-time Bluetooth signal detection. This dynamic approach improves power saving efficiency by accurately responding to actual user presence conditions while maintaining relatively simple implementation through standardized Bluetooth protocol usage.
