Solution Overview
Problem
Current wireless power transmission methods are inefficient and cumbersome, requiring extra chargers or plugs, and are not suitable for portable devices due to the need for direct alignment and the inefficiency of electromagnetic signal transmission, which wastes energy and can interfere with other devices.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electromagnetic signals are used for wireless power transmission, then power can be transmitted wirelessly to devices, but energy is wasted and interference with other devices occurs
Solution Approach 1:
The patent applies local quality by creating a focused energy pocket at a specific location in space rather than broadcasting energy omnidirectionally. The transmitter uses phase and amplitude modulation of RF signals to concentrate energy precisely where the receiver is located, thereby reducing energy waste in surrounding areas while enabling wireless power transmission.
2Ease of operation
If electromagnetic signals are used for wireless power transmission, then power can be transmitted wirelessly to devices, but interference with other electronic devices occurs
Solution Approach 1:
By concentrating the RF energy into a localized pocket at the receiver's position through precise phase and amplitude control, the patent minimizes the spread of electromagnetic interference to other electronic devices. The energy is delivered where needed without creating broad-spectrum interference.
3Loss of energy
If directional power transmission is used to reduce energy waste, then energy efficiency improves, but direct alignment between transmitter and receiver is required
Solution Approach 1:
The patent implements dynamics by continuously adjusting the phase and amplitude of RF signals transmitted from multiple antenna elements based on real-time feedback from the receiver. This dynamic adaptation allows the system to maintain a focused energy pocket even when the receiver moves or changes orientation, eliminating the need for manual alignment while preserving energy efficiency.
Solution Approach 2:
The system uses feedback from the receiver to the transmitter to continuously optimize the formation and positioning of the energy pocket. The receiver sends signals back to the transmitter, which then adjusts its antenna array configuration to maintain precise energy focus, thereby achieving both energy efficiency and ease of operation.
4Power
If high transmission power is used to overcome signal attenuation over distance, then received power increases, but energy waste and interference increase
Solution Approach 1:
The patent achieves high received power without proportionally increasing total transmission power by concentrating the transmitted energy into a focused pocket at the receiver's location. This spatial concentration ensures that most of the transmitted energy reaches the intended receiver rather than being dissipated over a wide area, thereby improving power delivery efficiency.

AI summary
The embodiments described herein include a transmitter that transmits a power transmission signal (e.g., radio frequency (RF) signal waves) to create a three-dimensional pocket of energy. At least one receiver can be connected to or integrated into electronic devices and receive power from the pocket of energy. The transmitter can locate the at least one receiver in a three-dimensional space using a communication medium (e.g., Bluetooth technology). The transmitter generates a waveform to create a pocket of energy around each of the at least one receiver. The transmitter uses an algorithm to direct, focus, and control the waveform in three dimensions. The receiver can convert the transmission signals (e.g., RF signals) into electricity for powering an electronic device. Accordingly, the embodiments for wireless power transmission can allow powering and charging a plurality of electrical devices without wires.
