Solution Overview
Problem
Conventional wireless power supply systems face challenges in managing communication between multiple remote devices, leading to data collisions and potential power inefficiencies due to the lack of effective timing coordination, especially when using separate communication channels like RF systems.
Innovation Solution
A communication timing system is implemented within the wireless power supply to assign specific time slots to each remote device, preventing data collisions by ensuring that information is transmitted only during designated times, thereby maintaining stable communication and power control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate communication channels like RF systems are used for multiple remote devices, then communication capability is improved, but data collisions and communication reliability deteriorate
Solution Approach 1:
The communication channel is segmented into distinct time slots, with each remote device assigned to a specific time slot for transmission. This temporal segmentation prevents data collisions by ensuring that only one device transmits at a time, thereby maintaining communication reliability while supporting multiple devices.
Solution Approach 2:
The system implements periodic time-slot-based communication cycles where each remote device transmits during its assigned slot in a repeating sequence. This periodic structure organizes multi-device communication systematically, preventing collisions while maintaining versatility.
2Reliability
If time slot assignment is implemented to prevent data collisions, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The wireless power supply autonomously manages time slot assignment and communication coordination without requiring external control systems. The system automatically detects remote devices, assigns time slots, and enforces transmission timing, which simplifies the overall system architecture while maintaining high communication reliability.
3Reliability
If communication timing control is implemented, then data collision prevention is improved, but power transfer efficiency may deteriorate due to coordination overhead
Solution Approach 1:
The communication and power transfer operations are merged into a unified system where communication occurs during designated time slots within the power transfer cycle. This integration allows the system to maintain reliable collision-free communication while minimizing overhead, as the communication infrastructure shares resources with the power transfer function.

Implementation Method 1
A typical inductive power transfer system includes an inductive power supply that uses a primary coil (or a transmitter) to wirelessly transfer energy in the form of a varying electromagnetic field
Implementation Method 2
a remote device that uses a secondary coil (or a receiver) to convert the energy in the electromagnetic field into electrical power
Implementation Method 3
Backscatter modulation relies on the principle that the impedance of the remote device is conveyed back to the power supply through reflected impedance. With backscatter modulation, the impedance of the remote device may be selectively varied to create a data stream
