Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless power transmission is extended to larger distances and areas, then power coverage is improved, but EMF exposure risk increases
Solution Approach 1:
The patent segments the transmission field into multiple zones and transmits power waves sequentially to different segments rather than simultaneously across the entire area. This allows the system to expand coverage area while controlling EMF exposure by limiting the active transmission zone at any given time, thus resolving the contradiction between larger coverage and reduced EMF risk.
2Reliability
If sensors continuously monitor the transmission field to identify sensitive objects, then safety is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by having sensors continuously scan and identify sensitive objects in the transmission field before power wave transmission begins. The system maps the transmission field in advance, identifies regions to avoid, and stores this information for later reference. This preliminary monitoring establishes safety compliance while managing complexity through structured field mapping and region identification protocols.
3Adaptability or versatility
If power waves are dynamically adjusted to track moving devices, then adaptability is improved, but control complexity increases
Solution Approach 1:
The patent implements dynamics by enabling the system to adapt power wave transmission in real-time based on detected device positions and movements. The transmitter adjusts transmission parameters dynamically to track moving receivers, forming energy pockets at the current receiver location. This adaptability is achieved through continuous position monitoring and real-time parameter adjustment, resolving the contradiction between tracking capability and control complexity.
4Productivity
If energy pockets are formed at precise locations to power devices, then power transmission efficiency is improved, but measurement precision requirements increase
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors receiver position and power transfer efficiency, then adjusts transmission parameters accordingly. The feedback loop enables the system to maintain high power transmission efficiency by forming energy pockets at the precise receiver location while managing measurement precision requirements through iterative adjustment and validation of position and power parameters.

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.
