Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional wireless charging systems transmit power waves, then energy can be transmitted wirelessly, but the transmission distance is limited and devices must be proximately located within a magnetic field
Solution Approach 1:
The patent transitions from conventional two-dimensional planar charging surfaces to three-dimensional volumetric power transmission. Multiple transmitters positioned at different spatial locations generate power waves that converge in three-dimensional space to form energy pockets at target locations, enabling remote wireless charging beyond traditional proximity constraints
Solution Approach 2:
The system combines power waves from multiple transmitter sources in three-dimensional space. These power waves merge and converge at predetermined locations to form concentrated energy pockets, achieving reliable power transmission over extended distances through constructive interference and energy accumulation
2Adaptability or versatility
If conventional systems use fixed charging positions, then power transmission is simple, but user mobility is not contemplated and devices must remain within a narrow window of operability
Solution Approach 1:
The system dynamically tracks receiver devices in three-dimensional space using sensors and communication signals. Transmitters continuously adjust power wave transmission parameters including direction, amplitude, and phase based on real-time receiver location data, enabling mobile charging throughout a volumetric space rather than fixed positions
Solution Approach 2:
The system implements feedback loops where receivers communicate their location and power reception status to transmitters. Transmitters use this feedback to continuously optimize power wave transmission parameters, adjusting beam direction and energy concentration to maintain effective charging as devices move through the three-dimensional charging volume
3Productivity
If power waves are transmitted at high intensity, then charging efficiency is improved, but electromagnetic field exposure may exceed regulatory limits for human safety
Solution Approach 1:
The system concentrates power wave energy into localized three-dimensional energy pockets only at the specific spatial coordinates where receivers are located. Power transmission intensity is high only in these localized regions rather than throughout the entire transmission volume, enabling efficient charging while limiting broad EMF exposure
Solution Approach 2:
The system uses sensor data and heat-map information as intermediaries to mediate between power transmission intensity and safety constraints. These intermediaries provide real-time environmental awareness, allowing the system to adjust power wave transmission to avoid exceeding EMF exposure limits in occupied zones while maintaining charging efficiency in target zones
4Ease of operation
If conventional systems transmit power in a single direction, then transmission control is simple, but the system cannot effectively manage power wave production for directionality purposes in three-dimensional space
Solution Approach 1:
The system segments the transmission space into multiple directional zones and uses separate transmitter units or antenna elements for each zone. Each segment can independently control power wave transmission in its specific direction, enabling sophisticated three-dimensional power distribution while maintaining relatively simple control for each individual segment

AI summary
Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (e.g., frequency, amplitude, phase, gain, direction), converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pockets of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy.
