Coordinated Power State Control for Hybrid System Architectures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Dynamic Power Management techniques are ineffective in reducing power consumption when both systems in a hybrid system architecture are operating cooperatively, as they are designed for standalone systems and do not account for coordinated power management between integrated systems.
Innovation Solution
A state control method where one system detects events and determines its own and another system's state, generating control commands to adjust their power states cooperatively, allowing for different power consumption modes based on user interactions and system needs, such as switching between active, dormant, and power-off states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If Dynamic Power Management technique is applied to standalone systems, then power consumption is reduced, but it cannot achieve power-saving when both systems in hybrid architecture are operating cooperatively
Solution Approach 1:
The power management function is segmented into two independent modules: one for managing the first system's power state and another for managing the second system's power state. Each module independently detects events, determines system states, and executes control commands appropriate to its system, allowing coordinated power management across both systems while maintaining operational independence.
Solution Approach 2:
The power management apparatus is designed with universal functionality to handle multiple scenarios: when the first system operates independently, when the second system operates independently, and when both systems operate cooperatively. The same apparatus adapts its control strategy based on the operational mode, making it versatile across different usage contexts.
2Adaptability or versatility
If systems operate cooperatively in hybrid architecture, then functional versatility is improved, but power consumption cannot be reduced
Solution Approach 1:
The power management system dynamically adjusts the operational states of both systems based on real-time event detection and current system states. When cooperative operation is detected, the system activates both systems; when independent operation is detected, the system powers down the first system while keeping the second system active, thereby dynamically optimizing power consumption according to functional requirements.
Solution Approach 2:
The system changes the operational parameters (power states) of the first and second systems based on detected events and current states. By transitioning systems between active and power-off states according to operational needs, the patent achieves parameter optimization that reduces power consumption while maintaining necessary functionality.
3Use of energy by moving object
If the first system is powered off to save energy, then power consumption is reduced, but the system cannot respond to user operations
Solution Approach 1:
The second system acts as an intermediary that remains active even when the first system is powered off. It can independently detect user operations and handle basic functions, providing a bridge that maintains system responsiveness without requiring the first system to remain powered on, thus balancing power savings with operational availability.

AI summary
The embodiments of the present application provide a method and a state control apparatus as well as a portable terminal. The method is applied in a first system connected to a second system and includes: detecting, by the first system, a first event; determining a first state of the first system and a second state of the second system when the first event is a first predetermined event; obtaining a predetermined policy including a first control command and a second control command based on the first state of the first system, the second state of the second system and the first predetermined event; and controlling, by the first system, its own state based on the first control command and transmitting the second control command to the second system such that the second system is switched from the second state to a fourth state. The second system has different power consumptions in the second state and the fourth state. With the embodiments of the present application, in a portable terminal of hybrid system architecture, the system states of the first and second systems can be controlled in a coordinated manner, such that the power consumption can be reduced when both systems are operating cooperatively.
