Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Asset tracking systems face limitations due to power and communication constraints, leading to channel collisions and unreliable tracking when numerous device nodes are concentrated, which hampers the effective management and location of assets in environments like warehouses.
Innovation Solution
A device node role management system that dynamically manages roles and power levels of device nodes in aggregated node groups, enabling them to perform specific functions by determining their roles based on information obtained and adjusting their power states to optimize communication and reduce channel collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If numerous device nodes are concentrated in aggregated node groups for asset tracking, then the system can track more assets simultaneously, but channel collisions increase and communication reliability deteriorates
Solution Approach 1:
The system segments device nodes into different roles (routing nodes, endpoint nodes, power transfer nodes) within aggregated node groups. This segmentation allows nodes to specialize in specific functions, reducing communication conflicts and improving reliability while maintaining high asset tracking capacity.
Solution Approach 2:
The system dynamically assigns and changes node roles based on current system conditions, power availability, and communication needs. Nodes can transition between different power states and roles adaptively, allowing the system to optimize communication reliability while maintaining high productivity in dense environments.
2Use of energy by moving object
If device nodes operate with limited power constraints, then energy consumption is reduced, but the ability to perform communication and tracking functions deteriorates
Solution Approach 1:
Device nodes dynamically adjust their power states and functional capabilities based on available energy and system needs. Nodes can transition between low-power sleep modes and high-power active modes, enabling them to perform tracking and communication functions when energy is available while conserving power when resources are limited.
Solution Approach 2:
The system changes operational parameters such as transmission power, sampling frequency, and processing intensity based on energy availability. This allows device nodes to maintain essential tracking functions with limited power while being able to enhance capabilities when energy resources increase.
3Productivity
If device nodes are assigned specific roles in aggregated groups, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The system divides device nodes into specific roles (routing, endpoint, power transfer) with defined responsibilities. This segmentation improves communication efficiency by reducing unnecessary transmissions and optimizing data flow, while the modular role structure actually simplifies management compared to unstructured peer-to-peer interactions.

AI summary
A method for managing roles of device nodes in an aggregated system. Information regarding a device node of an aggregated node group is determined. Each device node of the aggregated node group has multiple power level states. One of a plurality of roles of the device node is determined based upon the information. Each role has an associated power level state. The power level state associated with the role or function of the device node is enabled. The device node is instructed to actuate the determined role.
