Wireless Power Sharing in Mesh Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless power transmission networks, terminals distant from the power supply apparatus receive insufficient power, leading to reduced usage time, while those closer receive sufficient power, causing uneven power distribution among network terminals.
Innovation Solution
A wireless communication apparatus and system that acquires and manages power situations across the network, allowing for wireless power supply requests and distribution based on remaining power amounts and connection to a power source, enabling terminals to share power and maintain network stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless power transmission is performed from a fixed power supply apparatus, then terminals adjacent to the power supply receive sufficient power, but terminals distant from the power supply receive insufficient power
Solution Approach 1:
The system segments the power supply function by allowing any terminal with sufficient power to act as a power supply node. Instead of a single centralized power supply apparatus, multiple distributed terminals can provide power to others, creating a mesh-like power distribution network that extends coverage throughout the wireless network.
Solution Approach 2:
The patent merges the roles of power consumer and power provider within the same network. Terminals that receive sufficient power from the main power supply apparatus can simultaneously provide power to distant terminals, combining the functions of power reception and power transmission in a multi-terminal system to achieve broader network coverage.
2Reliability
If terminals with sufficient power supply power to terminals with insufficient power, then power distribution becomes more balanced, but the complexity of power management increases
Solution Approach 1:
The system implements feedback mechanisms where terminals continuously report their power status (sufficient or insufficient) to the network. Based on this feedback, the system automatically determines which terminals should provide power and which should receive power, enabling dynamic power management that adapts to changing network conditions without manual intervention.
Solution Approach 2:
Terminals autonomously determine their own power needs and capabilities, and self-organize into power provider and power receiver roles based on their current power status. The system enables terminals to independently participate in power sharing without requiring complex centralized control, reducing overall management complexity while maintaining network stability.
