Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vendor-specific power limit management interfaces are used, then hardware compatibility is achieved, but device complexity and project difficulty increase due to the need for diverse interfaces
Solution Approach 1:
The patent implements a universal power limit management interface that can communicate with multiple hardware components from different vendors (CPU, GPU, storage, display, etc.). This single standardized interface replaces the need for multiple vendor-specific interfaces, reducing device complexity while maintaining broad hardware compatibility and adaptability
2Reliability
If individual component-level power control is implemented, then component-specific optimization is achieved, but overall system power allocation becomes sub-optimal
Solution Approach 1:
The patent merges individual component power control capabilities into a centralized power limit management system. The controller receives power-related data and operational state data from all components, calculates optimized power allocation across the entire system, and coordinates control signals to actuators for each component. This unified approach ensures overall system power allocation efficiency while maintaining component-specific optimization through targeted control signals
3Productivity
If centralized power management is implemented, then overall power allocation optimization is achieved, but system complexity increases due to data collection and processing requirements
Solution Approach 1:
The patent introduces a centralized controller as an intermediary component that manages power allocation. The controller receives standardized power-related data and operational state data from various hardware components through a unified interface, processes this information to calculate optimized power allocation, and sends control signals to actuators. This intermediary architecture simplifies the overall system by providing a single point of coordination rather than requiring direct complex interactions between all components
Data Source
AI summary
Systems and methods are provided for implementing centralized platform-agnostic power limit management functionalities. A power limit management system includes an input interface, an output interface, and a controller that is part of an operating system of a computing device and that is configured to: receive, via the input interface, (a) power-related data associated with power supplied from a power source device for the computing device; and (b) operational state-related data associated with computing device components. The controller is further configured to: calculate power allocation for a computing device component(s), based on the power-related data and the operational state-related data; and generate a control signal for controlling power consumption for each computing device component, based on the power allocation. For each computing device component, the controller is further configured to send, via the output interface, the control signal to a corresponding actuator to control power consumption by the computing device component.
