Solution Overview

Problem

Current wireless power transfer technologies are limited in their ability to enable bidirectional power sharing over long distances within wireless mesh networks, as they typically allow only unidirectional power transmission and have restricted range and efficiency.

Innovation Solution

A system and method for wireless power sharing among nodes in a wireless mesh network, where each node acts as an 'electrical power-sharing hub' equipped with transmitters, receivers, and controllers, enabling bidirectional power transfer by requesting and relaying power through multiple intermediate hubs, extending the transmission range beyond conventional limits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If wireless power transfer is used to transmit power over long distances, then the transmission range is extended, but the efficiency of power transfer deteriorates due to significant power loss

Engineering Contradiction:
Improvetransmission distanceVSAvoidpower transfer efficiency
Core Design Contradiction:
Length of stationary objectVSLoss of energy

Solution Approach 1:

The patent divides the long-distance power transmission path into multiple short-segment hops through intermediate relay nodes. Each node receives power from its neighbor and forwards it to the next node, creating a mesh network where power is transmitted in discrete segments rather than as a single long-distance transmission, thereby maintaining efficiency while extending range.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediate relay nodes that act as mediators in the power transmission chain. These nodes receive power wirelessly from one node and re-transmit it to the next node, enabling long-distance power transfer through a series of short-range transmissions rather than a single long-range transmission, thus preserving efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If unidirectional power transmission is used, then the system complexity is reduced, but the adaptability of the network deteriorates as bidirectional power sharing is not enabled

Engineering Contradiction:
Improvebidirectional power sharing capabilityVSAvoidnetwork control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs each network node with universal functionality to both transmit and receive power wirelessly. Each node is equipped with identical transmitter and receiver components, enabling any node to act as either a power source or a power recipient depending on real-time network conditions, thus achieving bidirectional power sharing without requiring specialized hardware for different roles.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements dynamic role assignment where nodes can switch between transmitting and receiving modes based on real-time power availability and network demands. The system continuously monitors power status and dynamically adjusts which nodes transmit and which receive, enabling flexible bidirectional power sharing that adapts to changing conditions without manual reconfiguration.

Inventive Principle:
Principle #15Dynamics

3Reliability

If a single power source is used, then the device complexity is reduced, but the reliability of the system deteriorates during outages or high demand

Engineering Contradiction:
Improvesystem operation continuityVSAvoidnumber of power sources
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple distributed power sources within the mesh network into a unified power sharing system. Each node contributes its available power to the collective network, and the system intelligently routes power from multiple sources to meet the demands of any individual node, effectively merging the capabilities of multiple sources while maintaining system simplicity through centralized control logic.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent enables dynamic parameter changes in power availability at each node based on real-time conditions such as local power generation, storage status, and network demands. This allows the system to adaptively utilize different power sources and transmission paths, maintaining reliability during outages or high demand by rerouting power through alternative nodes with available capacity.

Inventive Principle:
Principle #35Parameter changes

AI summary

Electrical power is shared wirelessly among electrical power-sharing hubs in a wireless mesh network. Each electrical power-sharing hub includes one or more transmitters and receivers for wireless communications with other hubs and wireless power transfer technology to transmit or receive electrical power with other hubs. If electrical power at a respective electrical power-sharing hub is insufficient to power an electrical load on the hub, the hub wirelessly requests that a specific amount of electrical power be transmitted to it wirelessly from one or more neighboring electrical power-sharing hubs. At least one of the neighboring hubs may send a portion or all of the requested power. If the neighboring hubs do not have electrical power to share, a request for power is wirelessly transmitted to non-neighboring hubs, at least one of which may relay available electrical power wirelessly to the requesting hub via the wireless mesh network.
