Solution Approach 1:

The patent replaces traditional gradient-based optimization methods with a neural network-based system. The neural network is trained offline to learn the mapping from transmission parameters to power delivery performance, eliminating the need for real-time gradient calculations and objective function evaluations. This substitution of mechanical/computational optimization processes with an intelligent system achieves both high accuracy and computational efficiency.

Inventive Principle:

Solution Approach 2:

The patent performs preliminary training of the neural network offline using simulated or measured data before actual wireless power delivery operations. By pre-computing the optimization mappings and storing them in the neural network, the system avoids time-consuming real-time optimization calculations during actual power delivery, thus improving computational efficiency while maintaining optimization accuracy.
