Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If magnetic resonance is used to transmit power wirelessly, then power transmission capability is improved, but transmission distance is limited and devices must be proximately located within a magnetic field
Solution Approach 1:
The patent transitions from two-dimensional planar charging surfaces to three-dimensional volumetric power transmission. Multiple transmitters positioned at different spatial coordinates create overlapping electromagnetic fields that form chargeable volumes throughout the space, enabling devices to be charged from any orientation or position within the defined volume, thereby effectively increasing transmission distance and spatial coverage.
Solution Approach 2:
The patent combines multiple independent transmitter units into a coordinated multi-transmitter system. These transmitters work together to create a unified three-dimensional power field, merging their individual electromagnetic fields to form interconnected chargeable volumes that extend the overall transmission range and provide continuous power coverage throughout the service area.
2Device complexity
If conventional wireless charging systems are used, then simplicity is maintained, but the ability to track devices in three-dimensional spaces and manage power wave production is insufficient
Solution Approach 1:
The patent implements feedback mechanisms where receivers continuously report their position, orientation, and power reception status to the transmitter system. The transmitters use this feedback to dynamically adjust their beamforming parameters, power levels, and phase relationships, enabling precise tracking of devices in three-dimensional space and adaptive optimization of power delivery while maintaining manageable system complexity through automated control loops.
3Productivity
If power waves are transmitted to converge at predetermined locations, then energy delivery efficiency is improved, but exposure to EMF energy by humans or living beings within the transmission field may exceed regulatory limits
Solution Approach 1:
The patent applies local quality by creating highly focused pockets of energy at specific three-dimensional coordinates where receivers are located, rather than broadcasting power uniformly throughout the entire transmission volume. This concentrates electromagnetic energy only where needed for charging, minimizing unnecessary EMF exposure in surrounding areas and improving energy delivery efficiency by reducing wasted radiation.
Solution Approach 2:
The patent implements dynamic control of power wave transmission parameters including real-time adjustment of beam direction, power level, frequency, and phase based on receiver position, movement, and power needs. This dynamic adaptation allows the system to maintain efficient energy delivery to moving devices while continuously adjusting to prevent excessive EMF exposure, and to create null zones in areas where living beings are detected.
4Adaptability or versatility
If multiple transmitters are used to create three-dimensional power fields, then adaptability to device movement is improved, but system complexity and coordination requirements increase
Solution Approach 1:
The patent designs transmitters with multi-functionality, enabling each transmitter unit to perform multiple roles: generating electromagnetic fields for power transmission, serving as sensors for detecting receiver presence and position, acting as communication nodes for coordinating with other transmitters, and functioning as adjustable beamforming elements. This universality reduces overall system complexity by eliminating the need for separate dedicated components for each function.
