Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rechargeable battery chargers are used, then batteries can be recharged, but access to an AC power outlet is required which may not always be available or conveniently located
Solution Approach 1:
The patent replaces the mechanical connection system (physical AC power outlet connection) with an electromagnetic field-based wireless power transmission system. The mechanical plug-and-socket interface is substituted by electromagnetic radiation that can be received wirelessly by the portable device, enabling power transfer without physical contact or proximity to AC outlets.
Solution Approach 2:
The patent introduces electromagnetic radiation as an intermediary medium to transfer power from the transmitter to the receiver. Instead of direct electrical connection, power is transmitted through electromagnetic fields that can penetrate space and obstacles, serving as a mediator that bridges the gap between power source and device without requiring direct contact or line-of-sight AC outlet access.
2Adaptability or versatility
If wireless power transmission is implemented, then power delivery without AC connection is enabled, but system complexity increases with multiple boards and components
Solution Approach 1:
The Central Controller Board is designed as a universal platform that integrates multiple functions: power management, communication processing, antenna control, and system coordination. This multi-functional design consolidates what could be separate specialized components into a single integrated board, reducing overall system complexity while maintaining wireless power delivery capability.
Solution Approach 2:
The patent merges multiple control functions and components onto a single Central Controller Board, including power management circuits, communication interfaces, and antenna control logic. This consolidation approach combines what could be distributed across multiple separate boards into one integrated unit, simplifying the system architecture while enabling wireless power transmission.
3Loss of energy
If adaptive phased antennas and retrodirective technology are used, then power transfer efficiency is improved, but controller board functionality and complexity increase
Solution Approach 1:
The patent implements dynamic antenna beamforming capabilities where the Central Controller Board continuously adjusts the phase and amplitude of signals across multiple antenna elements based on real-time channel conditions. This dynamic adaptation allows the system to optimize power transfer efficiency by directing energy precisely toward the receiver while compensating for environmental changes, device movement, and multipath effects.
Solution Approach 2:
The system incorporates feedback mechanisms where the Central Controller Board receives information about power transfer conditions, device position, and channel characteristics, then uses this feedback to adjust antenna beamforming parameters in real-time. This closed-loop control enables the system to maintain optimal power transfer efficiency despite changing conditions, with the controller adapting its functionality based on actual system performance data.

AI summary
Various embodiments of the present technology generally relate to wireless power transmitter and antenna configurations for transmitting wireless power to one or more clients. In some embodiments, the wireless power transmitter includes boards having multiple antennas (i.e., an Antenna Matrix Board(s) (AMB)). The antennas can be on one side of each AMB board, while the control and power circuitry are on the reverse side. The antennas emit electromagnetic (EM) radiant energy that the client(s) receive, store, and/or use for communication with the charger or for the client device battery charging process. The antenna boards can be arranged in a configuration to increase (e.g., optimize) the amount of power transmitted to client(s). In various embodiments, the boards are arranged in polygonal shape as individual flat panels physically coupled to a support structure and attached to the CCB by plug in multiple pin connectors unique in mechanical design.
