Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If transmission power is boosted to increase received signal power over distance, then received signal power is improved, but energy wastage increases and harmful effects occur
Solution Approach 1:
The patent applies local quality by creating spatially localized energy pockets through constructive interference at specific locations. The antenna array generates high-energy regions precisely where receivers are located, while maintaining low energy levels elsewhere. This resolves the contradiction by delivering high power locally to receivers without requiring high transmission power throughout the entire space, thereby reducing energy wastage and harmful effects.
Solution Approach 2:
The patent transitions from conventional omnidirectional or directional transmission to three-dimensional pocket-forming in spatial frequency domain. By manipulating phase and amplitude across multiple antenna elements, the system creates focused energy pockets in 3D space, enabling efficient power transfer without the need for high overall transmission power, thus resolving the energy wastage problem.
2Loss of energy
If directional power transmission is used to enhance power transmission efficiency, then power transmission efficiency is improved, but computational complexity increases
Solution Approach 1:
The patent applies preliminary action by having receivers continuously transmit identification signals that allow the transmitter to pre-determine receiver locations and pre-form energy pockets before actual power transfer is needed. The microcontroller processes these signals to calculate optimal antenna configurations in advance, reducing real-time computational complexity while maintaining high transmission efficiency.
Solution Approach 2:
The patent segments the computational task by dividing the antenna array into multiple independent elements that can be controlled separately. Each antenna element's phase and amplitude are independently adjusted based on receiver location, allowing the system to achieve directional power transmission through simple per-element control rather than complex global optimization, thereby reducing computational complexity.
3Ease of operation
If conventional wireless transmission is used, then ease of operation is maintained, but power transmission efficiency deteriorates
Solution Approach 1:
The patent applies self-service by enabling receivers to automatically transmit their location information and by the transmitter to automatically form energy pockets directed at the receivers. The system self-adjusts to receiver positions without requiring manual configuration or complex user interaction, maintaining ease of operation while achieving high power transmission efficiency through automated pocket-forming.

AI summary
The present disclosure describes a methodology for wireless power transmission based on pocket-forming. The method includes a transmitter device capable of forming pockets of energy used by a receiver device to charge an electronic device such as a computers, cell phones, tablet and/or devices of the like. The method may include using an array of antennas at the transmitter to locate the position of a receiver device. The transmitter may identify the position of the device by capturing a signal from a receiving device using two subsets from the array of antennas. The subset of antennas may then be adjusted to form pockets of energy at the appropriate location of the receiving device. Previously stored data pertaining to each antenna in the array may serve to determine the proper adjustments for the entire array of antennas based on the results from the subsets used to capture the receivers signal.
