Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electromagnetic signals are transmitted over a distance to charge devices wirelessly, then charging convenience is improved, but energy loss increases proportionally to the square of the distance
Solution Approach 1:
The patent divides the wireless charging system into multiple transmitters that each create localized energy pockets rather than one transmitter covering a large area. This segmentation allows energy to be concentrated at specific locations, reducing overall energy loss while maintaining charging convenience across multiple devices.
Solution Approach 2:
The patent creates localized three-dimensional pockets of energy at specific spatial locations where receivers are positioned. By concentrating energy locally rather than distributing it broadly, the system achieves efficient energy transfer to individual devices while minimizing energy loss in the surrounding space.
2Power
If transmission power is boosted to maintain signal strength over distance, then received power is improved, but interference with other electronic devices increases
Solution Approach 1:
The patent confines high-power electromagnetic energy to localized three-dimensional pockets at specific receiver locations. This spatial confinement allows high transmission power to be used effectively at the target device without causing widespread interference to other electronic devices in the surrounding environment.
Solution Approach 2:
The patent uses algorithms and control systems as intermediaries to precisely direct and focus electromagnetic energy toward intended receivers. This intermediary control mechanism ensures that power is delivered accurately to the target device while minimizing stray energy that could interfere with other electronics.
3Device complexity
If a single transmitter serves multiple devices, then system complexity is reduced, but energy distribution efficiency decreases
Solution Approach 1:
The patent segments the transmitter array into multiple independent transmitting elements, each capable of creating its own localized energy pocket. This segmentation allows the system to serve multiple devices simultaneously with high energy distribution efficiency while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The patent creates a multi-functional transmitter system where each transmitting element can independently serve different receivers. This universal capability allows a single transmitter array to efficiently charge multiple devices simultaneously, combining the benefits of simplified system architecture with high energy distribution 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.
