Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supplies with wake-up functions continue to consume unnecessary power even when the computing system is turned off, as the standby module remains active, leading to increased energy consumption and inconvenience for users who must manually disable it.
Innovation Solution
A control circuitry is introduced that determines whether a standby voltage is required for a computing system and enables or disables the standby module accordingly, using a determination circuit, transistor, and optical coupler to manage the power supply nodes, allowing the standby module to be turned off when not needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the standby module remains active to provide wake-up function, then the computing system can be wake-up when needed, but unnecessary power consumption increases
Solution Approach 1:
The standby module's operational state is made dynamic rather than static. The control circuitry automatically adjusts the standby module's state based on real-time detection of wake-up signal presence, transitioning between enabled and disabled states to optimize power consumption while maintaining wake-up capability when needed.
Solution Approach 2:
The system performs self-diagnosis and self-adjustment regarding power management. The control circuitry autonomously detects whether the motherboard supports wake-up functions and automatically configures the standby module accordingly, eliminating the need for manual user intervention and achieving optimal power savings automatically.
2Loss of energy
If the user manually disconnects the power supply to save power, then unnecessary power consumption is reduced, but user convenience decreases
Solution Approach 1:
The power management function is automated through the control circuitry that continuously monitors system requirements and autonomously adjusts the standby module's power state. This self-service mechanism eliminates the need for users to manually disconnect power plugs or switches, achieving both power savings and user convenience simultaneously.
Solution Approach 2:
The control circuitry implements a feedback mechanism by continuously monitoring the motherboard's wake-up signal capability and adjusting the standby module's operational state accordingly. This closed-loop control ensures power consumption is optimized based on actual system needs without requiring user awareness or action.
3Reliability
If the standby module is always on to support wake-up function, then the system can respond to wake-up signals, but power consumption increases even when not needed
Solution Approach 1:
The standby module transitions from a static always-on state to a dynamic state that adapts based on detected requirements. The control circuitry enables the standby module only when wake-up functionality is detected as needed, and disables it when not required, creating a dynamic power management system that balances reliability and energy efficiency.
Solution Approach 2:
The operational parameters of the standby module are changed based on detected system requirements. The control circuitry modifies the power supply state parameter of the standby module between enabled and disabled states according to the presence or absence of wake-up signal support, optimizing both reliability and energy consumption.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces unnecessary power consumption and provides user convenience by automatically disabling the standby module when not required, aligning with environmental protection goals without requiring users to physically disconnect the power supply.
Implementation Method 1
The optical coupler is electrically coupled to the transistor. When the transistor is turned on, the optical coupler shorts the two nodes of the standby module to enable the standby module, and when the transistor is turned off, the optical coupler disconnects the two nodes of the standby module to disable the standby module.
