Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless transmitter device is constructed to only transfer energy to a particular receiver device, then the energy transfer reliability is improved, but the device versatility deteriorates
Solution Approach 1:
The transmitter device is divided into multiple discrete transmitter coils arranged in an array, where each coil can be independently controlled. This segmentation allows the system to selectively activate only the coil or coils needed for a particular receiver device, ensuring reliable energy transfer while maintaining the ability to adapt to different device positions and types.
Solution Approach 2:
The system dynamically selects and activates specific transmitter coils based on the position and requirements of the receiver device. This dynamic adaptation allows the transmitter to optimize energy transfer for each device while maintaining versatility across multiple device types and positions.
2Adaptability or versatility
If multiple discrete transmitter coils are used to support multiple receiver devices, then the device versatility is improved, but the device complexity increases
Solution Approach 1:
Multiple discrete transmitter coils are merged into a single integrated array structure with shared control circuitry. This combining approach allows the system to support multiple receiver devices simultaneously while managing complexity through unified control and coordination of the individual coils.
Solution Approach 2:
The transmitter device is designed with universal functionality to support multiple types of receiver devices through a single multi-coil array. The system can adapt to different device positions, orientations, and power requirements by selectively activating appropriate coils, eliminating the need for multiple specialized charging devices.
3Productivity
If selective coil energization is implemented based on receiver position, then the energy transfer efficiency is improved, but the control complexity increases
Solution Approach 1:
The system performs preliminary detection of receiver device position and characteristics before activating the transmitter coils. This preliminary action allows the control system to pre-determine which coils should be activated, optimizing energy transfer efficiency while managing control complexity through advance preparation and coordination.

AI summary
A wireless transmitter device is configurable and operable to transfer energy to multiple receiver devices at the same time. The transmitter device includes at least one layer of discrete transmitter coils. The wireless transmitter device is configured to enable one or more sections of a charging surface to transfer energy by selectively choosing one or more discrete transmitter coils in the wireless transmitter device based on the position of the receiver device on the charging surface. The size and shape of each section of the charging surface that is used to transfer energy to a receiver device can change dynamically based on each receiver device. Additionally, the process of transferring energy to each receiver device may be adjusted during energy transfer based on conditions specific to each receiver device.
