Solution Overview
Problem
Existing wireless power transfer systems are limited in their ability to efficiently charge mobile platforms in motion, requiring strict alignment and limited coverage areas, making them unsuitable for dynamic and large-area power transfer.
Innovation Solution
A near-field spatial conductors system with continuous signal and ground conductors, connected to a single alternating power source, maintains constant and continuous electromagnetic coupling with receiving conductors, allowing for uninterrupted power transfer to mobile platforms without alignment constraints, enabling efficient wireless charging over large areas and volumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional wireless charging systems use magnetic induction or magnetic resonance with stationary platforms, then power transfer efficiency is maintained within limited areas, but the system cannot effectively power mobile platforms in motion over large areas
Solution Approach 1:
The system divides the charging infrastructure into multiple spatial conductors arranged in sequences along the mobile platform's path. Each conductor segment independently contributes to the overall electromagnetic field, enabling continuous coverage over large areas while maintaining efficient coupling with the moving receiver
Solution Approach 2:
The patent transitions from traditional planar charging pads to three-dimensional spatial conductors that extend in multiple dimensions. This dimensional expansion allows the system to cover larger volumes and areas, accommodating mobile platforms moving through space rather than requiring strict alignment on a two-dimensional surface
2Area of stationary object
If multiple charging pads are used to cover larger areas, then area coverage increases, but the system requires complex detection apparatus and strict alignment
Solution Approach 1:
Multiple spatial conductor segments are merged into a unified system that operates cooperatively. The conductors are arranged and controlled to create a continuous electromagnetic field along the mobile platform's trajectory, eliminating the need for complex detection and switching mechanisms that would be required if separate charging pads operated independently
Solution Approach 2:
The spatial conductor system serves multiple functions simultaneously: it provides continuous power transfer, defines the charging volume, and guides the mobile platform without requiring separate detection apparatus. The same conductors that generate the electromagnetic field also serve as the reference for maintaining proper coupling
3Loss of energy
If traditional systems require strict alignment between transmitter and receiver, then power transfer efficiency is maintained, but the system cannot accommodate mobile platforms in motion
Solution Approach 1:
The system is designed to dynamically adapt to the mobile platform's position and motion. The spatial conductors are arranged and controlled to maintain optimal electromagnetic coupling as the receiver moves through the charging volume, automatically adjusting the field distribution to track the moving target without requiring mechanical alignment adjustments
Solution Approach 2:
The continuous arrangement of spatial conductors along the mobile platform's path ensures uninterrupted power transfer. As the platform moves from one conductor segment to the next, the electromagnetic field continuously follows, maintaining efficient coupling throughout the entire trajectory without gaps or interruptions that would occur with discrete, statically-aligned charging pads

AI summary
Near field spatial conductors' system and method configured to cover relatively large area and volume while maintain high electromagnetic (EM) coupling and high-power transfer efficiency between the transmitter/s and the receiver/s as part of a mobile platform (essentially for transport and locomotion) wireless powering and charging system. A constant and continuous EM coupling between a continuous signal conductor, a continuous ground conductor (both connected to same alternation power source) and a receiving conductor allow a mobile platform to receive a substantially constant stream of power without intervals of resonance and coupling along the path of an arrangement of said conductors.
