Adjustable Resonant Capacitor for Wireless Charging Efficiency

The patent applies the dynamics principle by transforming the fixed capacitance value into a dynamically adjustable one. The resonant capacitor is designed with multiple selectable capacitance values (e.g., 400nF, 500nF, and other values) that can be switched based on the actual working frequency of the transmitter. This allows the receiver to adapt its resonant frequency to match the transmitter's frequency, thereby optimizing wireless charging efficiency while maintaining reasonable structural complexity through discrete switching rather than continuous adjustment.

The patent implements parameter changes by modifying the capacitance value parameter of the resonant capacitor. Instead of using a single fixed capacitance value, the system provides multiple capacitance options (400nF, 500nF, and additional values) that can be selected according to the transmitter's operating frequency. This parameter variation enables the receiver to maintain optimal resonance conditions across different frequency scenarios, directly addressing the efficiency loss problem while keeping the implementation practical through discrete parameter selection.

The patent implements universality by designing the resonant capacitor to serve multiple functions: it acts as both a fixed capacitor for basic resonance and a variable capacitor for frequency adaptation. The same capacitor component can operate at different capacitance values (400nF, 500nF, or other values) depending on the transmitter's operating conditions, eliminating the need for separate capacitors for each frequency scenario and reducing overall device complexity while maintaining efficiency.

The patent applies segmentation by dividing the resonant capacitor into multiple discrete capacitor branches or selectable capacitance values (400nF, 500nF, and other specific values). Each segment represents a predetermined capacitance value that can be independently selected based on the transmitter's operating frequency. This segmentation approach simplifies manufacturing precision requirements compared to continuous variable capacitors, as each discrete value can be precisely manufactured and calibrated once, then reused across multiple devices.

The patent implements preliminary action by pre-calibrating and presetting multiple capacitance values (400nF, 500nF, and other values) during the manufacturing process. These predetermined values are optimized for specific frequency ranges, so the receiver can directly select the appropriate pre-calibrated capacitance value based on the transmitter's operating frequency without requiring complex real-time calibration. This preliminary preparation reduces manufacturing precision challenges by shifting the calibration burden to the factory setting phase rather than field operation.
