Dynamic Power Control for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices consume excessive power due to poor control intelligence, particularly when running application programs, leading to elevated power consumption.
Innovation Solution
A control method that acquires operation data and response information from target components in electronic devices to adjust power control parameters, optimizing power consumption by determining matching operation modes and adjusting power limits accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the processor runs at high operating power with turbo acceleration to ensure smooth application program execution, then the application program does not freeze and runs smoothly, but the power consumption of the electronic device is elevated and exceeds actual needs
Solution Approach 1:
The patent implements dynamic power adjustment by continuously monitoring operation data and response information, then adaptively changing power control parameters. The processor transitions between different power states (high performance mode during turbo acceleration, low power mode during idle periods) based on real-time system state, resolving the contradiction between maintaining smooth execution and reducing power consumption.
Solution Approach 2:
The patent establishes a feedback control loop that monitors operation data (CPU usage, memory access, storage operations) and response information (application responsiveness, user interactions) to dynamically adjust power control parameters. This feedback mechanism ensures the processor maintains adequate performance when needed while reducing power consumption when the system is responsive and idle, directly addressing the technical contradiction.
2Productivity
If the processor performs turbo acceleration when the application program is just started, then the application program starts quickly and runs smoothly, but the power consumption increases beyond what the application actually needs
Solution Approach 1:
The system dynamically adjusts power control parameters based on real-time monitoring of operation data and response information. During application startup, the processor temporarily operates at high power for turbo acceleration to ensure quick launching, then automatically transitions to lower power states once the application is fully loaded and the system returns to responsive operation, thus achieving fast startup without sustained high power consumption.
Solution Approach 2:
The patent implements periodic monitoring of operation data and response information, with power control parameters being adjusted in periodic cycles. This allows the system to provide intensive processing power only during necessary periods (application startup, heavy processing tasks) and switch to energy-efficient modes during idle periods, resolving the contradiction between productivity and power consumption.
