Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power management techniques for electronic devices, especially in heterogeneous networks, lack effective collaboration and synchronization across nodes, leading to inefficient energy conservation and heat dissipation, particularly in mobile devices where battery power is a concern.
Innovation Solution
Implementing a collaborative power management system using power management packet data units (PMPDU) within a network link power management (NLPM) protocol to communicate and synchronize power states between nodes, enabling power gating and clock gating of hardware elements to conserve energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power management techniques are implemented individually at each node, then local energy conservation is achieved, but collaborative energy efficiency and system-wide heat dissipation improvement are lost
Solution Approach 1:
The patent combines individual node power management with collaborative power management by integrating PMPDU communication mechanisms into existing power management frameworks. This merging allows nodes to share power state information and coordinate their power states, achieving system-wide energy efficiency while maintaining local energy conservation capabilities.
Solution Approach 2:
The patent implements feedback mechanisms where nodes exchange power state information through PMPDUs, allowing the system to monitor and adjust power states collaboratively. This feedback loop enables dynamic optimization of energy consumption across the entire system based on real-time power state information from all nodes.
2Device complexity
If nodes operate independently without power state synchronization, then device complexity is reduced, but heat dissipation efficiency and overall system performance deteriorate
Solution Approach 1:
The patent introduces PMPDUs as intermediary structures that facilitate power state communication and synchronization between nodes. These standardized data units act as mediators that carry power state information without requiring complex custom communication protocols, thus maintaining low implementation complexity while achieving effective heat dissipation coordination.
3Loss of energy
If power states are not synchronized across nodes, then communication overhead is reduced, but energy conservation effectiveness and battery life extension are limited
Solution Approach 1:
The patent changes the parameter of power state representation by using standardized PMPDU structures with specific fields for power state information. This parameter standardization enables efficient encoding and transmission of power state data, achieving effective energy conservation synchronization with minimal communication overhead.
