Personal Area Fabric Power Management via State Configuration Engine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing networked devices lack the ability to cooperate at a network level to optimize and manage power consumption effectively, with existing solutions only addressing power management for individual nodes or pairs, not for a mesh of multiple nodes.
Innovation Solution
A personal area fabric with networked nodes, each equipped with a state configuration engine that aggregates power profiles and derives a fabric-level power configuration to optimize power consumption across all nodes in response to user-defined triggers or criteria, allowing for granular control over power states and communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If each node manages power independently, then device complexity is reduced, but network-level power optimization is lost
Solution Approach 1:
The patent combines individual node power management with network-level coordination by having nodes exchange power state information and receive coordinated power management commands. The state configuration engine aggregates power profiles from multiple nodes and derives fabric-level power configurations, merging decentralized node autonomy with centralized optimization to achieve network-wide power efficiency without excessive complexity
Solution Approach 2:
The state configuration engine acts as an intermediary between individual nodes and the network as a whole. It collects power state information from nodes, processes this information to determine optimal power configurations, and distributes coordinated power management commands back to nodes, enabling network-level optimization while maintaining relatively simple node implementations
2Reliability
If nodes synchronize power states, then power management coordination improves, but communication overhead increases
Solution Approach 1:
The system implements periodic power state synchronization where nodes exchange power state information at scheduled intervals rather than continuously. The state configuration engine periodically aggregates power profiles and derives updated fabric-level power configurations, reducing communication overhead while maintaining effective power coordination across the network
Solution Approach 2:
Nodes pre-exchange power state information and the state configuration engine pre-computes fabric-level power configurations based on aggregated power profiles. This preliminary action allows nodes to be instructed to transition to coordinated power states without requiring real-time communication during state changes, reducing immediate communication energy requirements
3Use of energy by moving object
If fabric-level power configuration is implemented, then network power optimization improves, but device complexity increases
Solution Approach 1:
The patent segments power management functionality into distinct components: individual node power state monitoring, power profile aggregation at the state configuration engine, fabric-level configuration derivation, and distributed command execution. This segmentation allows each component to remain relatively simple while achieving complex network-level power optimization through coordinated operation of the segments

AI summary
A power management system for a personal area fabric having a plurality of nodes is presented. The system implements power management functions at the fabric-level via fabric-level power profiles reflecting the aggregated power profiles from some or all of the nodes in the fabric. The fabric-level power profiles are used to trigger the implementation of fabric power configurations that cause the individual nodes to modify their operations in the interest of a fabric-level power management plan.
