Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless power transfer systems face conflicts between time protocols in data communication, leading to instability and safety issues during power control, particularly when different devices with varying power levels and communication protocols interact.
Innovation Solution
Implementing a method where the wireless power transmitter sends a second data packet within a first timeout, with the timeout value being greater than the time protocol for at least one CE packet, ensuring stable and safe data communication and power control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless power transmitter uses a timeout value greater than the time protocol for CE packets, then data communication stability is improved, but communication response time increases
Solution Approach 1:
The system dynamically adjusts the timeout value based on the specific communication scenario. By setting the timeout greater than the CE packet time protocol only when needed for stability, while allowing faster timeouts in other scenarios, the system achieves both stability and responsiveness without being constrained by a fixed timeout value.
Solution Approach 2:
The timeout parameter is changed from a fixed value to a variable that can be adjusted based on communication requirements. This allows the system to optimize between stability and response time by selecting appropriate timeout values for different operational contexts, resolving the contradiction between reliability and time loss.
2Adaptability or versatility
If different devices with varying power levels and communication protocols interact, then system versatility is improved, but protocol conflicts and control stability deteriorate
Solution Approach 1:
The wireless power transmitter is designed with universal communication capabilities that can handle multiple protocols and device types. By implementing a unified timeout management mechanism that works across different protocol scenarios, the system achieves versatile device compatibility while maintaining stable power control through consistent timeout handling.
Solution Approach 2:
The timeout mechanism serves as an intermediary layer between diverse communication protocols and the power control system. By standardizing timeout values that are greater than CE packet protocols, this intermediary ensures stable power control while allowing various devices with different protocols to interact, thus resolving protocol conflicts.
3Object-affected harmful factors
If the system prioritizes stable power control through extended timeout values, then power transmission safety is improved, but data communication efficiency decreases
Solution Approach 1:
The system applies extended timeout values selectively rather than universally. By using timeout values greater than CE packet protocols only in scenarios where power transmission safety is critical, while allowing more efficient timeouts in stable scenarios, the system achieves safety without excessive impact on overall communication efficiency.

Implementation Method 1
The magnetic induction method corresponds to a method transmitting power by using electric currents that are induced to the coil of the receiver by a magnetic field, which is generated from a coil battery cell of the transmitter, in accordance with an electromagnetic coupling between a transmitting coil and a receiving coil.
Implementation Method 2
The magnetic resonance method is similar to the magnetic induction method in that is uses a magnetic field. However, the magnetic resonance method is different from the magnetic induction method in that energy is transmitted due to a concentration of magnetic fields on both a transmitting end and a receiving end, which is caused by the generated resonance.
