Solution Overview
Problem
Induction type power supply systems face challenges in synchronously transmitting data and power due to interference from high-power electricity, which affects data stability and increases manufacturing costs, and existing methods for data modulation are limited by power loss and system failure at high power outputs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high-power electricity is transmitted through induction coils, then power transmission efficiency is improved, but data stability deteriorates due to interference
Solution Approach 1:
The patent segments the power transmission and data transmission functions into separate time intervals. Power is transmitted during designated power transmission periods, while data is transmitted during dedicated data transmission periods. This temporal segmentation prevents interference between high-power electricity and data signals, maintaining both power transmission efficiency and data stability.
Solution Approach 2:
The system employs periodic alternation between power transmission mode and data transmission mode. By using periodic action with clearly defined transmission periods and receiving periods, the patent ensures that high-power electricity and data signals never overlap in time, thus preserving data stability while maintaining efficient power delivery.
2Ease of manufacture
If data transmission is conducted through induction coils during power supply, then manufacturing cost is reduced, but data transmission stability deteriorates due to interference
Solution Approach 1:
The patent divides the communication process into distinct segments: power transmission segments and data transmission segments. By separating these functions temporally while using the same induction coil infrastructure, the system maintains manufacturing simplicity without compromising data transmission stability during dedicated data periods.
Solution Approach 2:
The system uses periodic switching between power transmission and data transmission modes. This periodic action allows the same induction coil to serve dual purposes at different times, reducing manufacturing costs while ensuring data transmission stability through dedicated interference-free time slots.
3Power
If power is increased to maximum level, then power delivery efficiency is improved, but system reliability deteriorates due to heating effects and interference
Solution Approach 1:
The patent implements periodic alternation between high-power transmission mode and data transmission mode. During power transmission periods, maximum power can be delivered efficiently; during data transmission periods, power is reduced to prevent heating and interference. This periodic switching maintains both power delivery efficiency and system reliability.
Solution Approach 2:
The system takes preliminary anti-action by reducing power before data transmission periods begin, preventing heating effects and electromagnetic interference that would occur if high power were maintained continuously. This proactive power management protects the system from thermal and electromagnetic damage while maintaining efficient power delivery during dedicated power periods.

AI summary
An operating clock synchronization adjusting method, for an induction type power supply system, includes receiving a plurality of data pulses, by a supplying-end module, according to a clock of a microprocessor of the supplying-end module, for generating a plurality of data frames. A period between first data pulses corresponding to starting bits of a first detecting data frame and a second detecting frame among the plurality of data frame is calculated, for acquiring a data frame period. A period between the first data pulse of the second data frame and a second data pulse of the second data frame is calculated, for acquiring a bit period. The bit period and a bit time threshold are compared for determining whether to adjust the clock of the microprocessor according to the data frame period and a frame time threshold.
