Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic resonance is used to wirelessly transmit energy, then power can be transmitted without wired connection, but the electronic device must be proximately located within a narrow magnetic field window
Solution Approach 1:
The patent transitions from conventional two-dimensional planar charging surfaces to three-dimensional volumetric power transmission. Multiple transmitters positioned at different heights and locations create overlapping electromagnetic fields that form a chargeable volume in 3D space, allowing receivers to be charged at various positions and orientations within this volume, thereby significantly improving user mobility and adaptability.
Solution Approach 2:
The system employs multiple transmitters that can independently or cooperatively serve different receivers simultaneously. Each transmitter can adapt its power waves to target specific receivers, and the system can dynamically reconfigure to serve multiple devices in different locations, making the charging system universally applicable to various user scenarios and device positions.
2Productivity
If conventional wireless charging systems transmit power waves, then energy can be delivered to devices, but the systems cannot identify and track device locations in three-dimensional space
Solution Approach 1:
The system incorporates sensors that continuously detect receiver positions and transmit this location data back to the transmitter system. This feedback loop enables the transmitters to dynamically adjust their power wave characteristics and targeting to maintain optimal charging efficiency as devices move within the 3D charging volume.
Solution Approach 2:
The system pre-configures sensor data collection and processing capabilities to identify and map device locations before power transmission begins. Heat-map data structures are prepared in advance to store and represent the three-dimensional spatial distribution of devices, enabling efficient real-time tracking and adaptive power delivery.
3Power
If power waves are transmitted to charge devices, then energy delivery is achieved, but EMF exposure limits may be exceeded
Solution Approach 1:
The system concentrates power transmission in localized regions where receivers are detected, creating focused pockets of energy rather than broadcasting power waves uniformly throughout the entire space. This localized approach delivers sufficient power to devices while minimizing unnecessary EMF exposure in surrounding areas where no devices are present.
Solution Approach 2:
The transmitters dynamically adjust their power output and beam direction based on real-time sensor data about receiver positions and environmental conditions. This dynamic adaptation allows the system to maintain effective charging power while automatically reducing EMF exposure levels in areas where devices are absent or where exposure limits are approaching.

AI summary
An example method disclosed herein includes: determining, by a transmitter, whether to transmit one or more power waves to a receiver location along a transmission path by comparing a receiver location and a path of the one or more power waves with a stored location of an entity to be excluded from receipt of power waves. The method also includes: measuring, by one or more sensors of the transmitter, power levels in a transmission field of the transmitter, the transmission field including the receiver location and the entity; and upon determining that (i) the entity to be excluded is not at the receiver location and not in the path and (ii) a measured power level at the receiver location does not exceed one or more permissible power levels for safe wireless power transmission, transmitting, by the transmitter, the power waves along the path to converge at the receiver location.
