Electronic Power Control Unit Segmentation for Conflict-Free Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power consumption parameter adjustment processes in electronic devices, such as laptops and tablets, are inefficient and prone to conflicts due to concurrent adjustments by built-in dynamic tuning technology (DTT) and resource control systems, leading to interdependent power level settings.
Innovation Solution
A control method and system that separates power consumption parameter adjustments into two control units, with a processing unit determining target parameters for each unit based on device state and application data, allowing independent adjustments by a first control unit for hardware-level parameters and a second control unit for software-level parameters, thereby reducing conflicts and optimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power consumption parameters are adjusted concurrently by both DTT and resource control system, then power management coverage is comprehensive, but parameter conflicts occur and adjustment efficiency deteriorates
Solution Approach 1:
The patent segments the power management system into two independent control units: DTT (Dynamic Thermal Management) and resource control system. Each unit manages specific power consumption parameters independently, avoiding conflicts while maintaining comprehensive coverage. The processing unit coordinates both units, allowing them to operate in parallel without interfering with each other's parameter adjustments.
2Adaptability or versatility
If multiple power consumption parameters are adjusted concurrently, then power management comprehensiveness is improved, but parameter interdependence increases and accuracy decreases
Solution Approach 1:
The patent divides power consumption parameters into distinct groups managed by different control units. DTT manages thermal-related parameters while the resource control system manages performance-related parameters. This segmentation eliminates parameter interdependence and ensures each parameter is adjusted independently with high accuracy based on its specific requirements.
3Manufacturing precision
If power consumption parameter adjustment process is lengthened to ensure accuracy, then parameter setting precision is improved, but adjustment efficiency deteriorates
Solution Approach 1:
The patent implements parallel adjustment processes where DTT and resource control system adjust their respective parameters simultaneously rather than sequentially. This parallel execution maintains high precision for each parameter while significantly reducing total adjustment time, as both control units operate independently and concurrently.
Solution Approach 2:
The processing unit pre-configures the adjustment parameters for both DTT and resource control system based on current device state and application requirements. This preliminary preparation allows both control units to execute their adjustments simultaneously without waiting for sequential processing, thereby maintaining precision while reducing overall adjustment time.

AI summary
A control method includes: receiving, via a processing unit in an electronic device, state parameters of the electronic device and/or running applications; determining, via the processing unit, a first target parameter and a second target parameter based on the state parameters and/or running applications, the first target parameter being used to determine a first power consumption parameter controlled by a first control unit, and the second target parameter being used to determine a second power consumption parameter controlled by a second control unit; in response to the processing unit sending the first target parameter to the first control unit, adjusting, via the first control unit, the first power consumption parameter based on the first target parameter; in response to the processing unit sending the second target parameter to the second control unit, adjusting, via the second control unit, the second power consumption parameter based on the second target parameter.
