Solution Overview
Problem
Current wireless power transmission methods are inefficient and cumbersome, requiring direct placement of devices within a specific range of the transmitter, are wasteful in energy transmission, and often interfere with other electronic devices, especially due to the attenuation of electromagnetic signals with distance and obstacles, making it difficult to charge portable electronic devices effectively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electromagnetic signal transmission power is boosted to increase received power over distance, then received signal power is improved, but energy wastage increases and interference with other electronic devices occurs
Solution Approach 1:
The patent applies local quality by creating concentrated energy pockets at specific locations rather than broadcasting energy uniformly in all directions. The system forms localized regions of high energy density where receivers are positioned, while areas without receivers receive minimal or no energy transmission. This resolves the contradiction by delivering sufficient power to receivers without wasteful omnidirectional transmission that causes energy loss and interference.
Solution Approach 2:
The patent transitions from traditional two-dimensional planar energy distribution to three-dimensional energy pocket formation. By utilizing volumetric space to create focused energy regions, the system achieves precise spatial control over energy delivery. This dimensional expansion enables the transmitter to concentrate power where needed while leaving surrounding spaces energy-free, thereby improving received signal power without proportional increases in energy wastage or interference.
2Power
If electromagnetic signal transmission power is boosted to increase received power over distance, then received signal power is improved, but interference with other electronic devices increases
Solution Approach 1:
The system implements local quality by creating spatially selective energy pockets that deliver high power only to specific locations where receivers are present. Areas without receivers experience minimal or no energy transmission, eliminating the interference problem that would result from omnidirectional high-power transmission. This resolves the contradiction by achieving high received signal power at target devices without causing harmful interference to other electronic devices in the vicinity.
Solution Approach 2:
The patent introduces communication protocols and control mechanisms as intermediaries between the transmitter and receivers. These intermediaries enable the system to identify receiver locations, establish energy pockets only where needed, and coordinate transmission timing. This mediation allows high-power transmission to occur selectively, improving received signal power while preventing interference with other electronic devices through intelligent spatial and temporal control.
3Loss of energy
If devices are placed within specific range of transmitter for charging, then power transmission efficiency is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies dynamics by making the energy pocket formation adaptive and responsive to receiver movement. Rather than requiring devices to remain stationary within a fixed range, the system dynamically adjusts the location and parameters of energy pockets to track moving receivers. This resolves the contradiction by maintaining high power transmission efficiency even when devices are moved, as the energy pockets automatically reposition to follow the receivers, thereby improving ease of operation without sacrificing efficiency.
Solution Approach 2:
The system implements feedback mechanisms where receivers communicate their position and status to the transmitter, which then adjusts energy pocket formation accordingly. This feedback loop enables the transmitter to maintain optimal power transmission efficiency regardless of device location or movement. By continuously adapting to receiver positions through feedback, the system eliminates the need for users to precisely position devices within specific ranges, thereby improving ease of operation while maintaining high transmission efficiency.
