Wireless Charging System with a Switchable Magnetic Core - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240296989 titled 'Wireless Charging System with a Switchable Magnetic Core
Simplified Explanation: The patent application describes an electronic device in a wireless power system that can be used with a removable accessory, such as a case. The device is capable of transmitting, receiving, or transferring wireless power through the case while it is attached to it. The device includes coplanar power transmitting and power receiving coils. The removable accessory features a switchable ferrimagnetic core and a coil that overlaps the core. The switchable ferrimagnetic core can operate in two states, with different magnetic properties, depending on the presence of a magnetic field from a permanent magnet in a wireless power transmitting device.
- The electronic device in the wireless power system can work with a removable accessory like a case.
- The device can transfer wireless power through the case when connected to it.
- It has coplanar power transmitting and power receiving coils for efficient power transfer.
- The removable accessory includes a switchable ferrimagnetic core and a coil that interacts with the core.
- The switchable ferrimagnetic core can change its magnetic properties based on the magnetic field from a permanent magnet in a wireless power transmitting device.
Potential Applications: 1. Mobile devices that can charge wirelessly through a case. 2. Wearable technology that can receive power wirelessly through accessories. 3. Smart home devices that can be powered without direct contact with charging pads.
Problems Solved: 1. Eliminates the need for wired charging connections. 2. Provides a convenient and efficient way to charge electronic devices. 3. Enables seamless integration of wireless power technology into everyday accessories.
Benefits: 1. Enhanced convenience for charging electronic devices. 2. Reduction in wear and tear on charging ports. 3. Improved user experience with wireless power technology.
Commercial Applications: Wireless charging technology integrated into accessories like cases can revolutionize the way electronic devices are powered, offering a convenient and efficient charging solution for various industries such as consumer electronics, wearables, and smart home devices.
Questions about Wireless Power System with Removable Accessory: 1. How does the switchable ferrimagnetic core in the removable accessory impact the efficiency of wireless power transfer? 2. What are the potential limitations of using a case with embedded wireless power technology for charging electronic devices?
Original Abstract Submitted
an electronic device in a wireless power system may be operable with a removable accessory such as a case. the device may convey wireless power to, from, or through the case while the device is coupled to the case. the device may have coplanar power transmitting and power receiving coils. the removable accessory may have an embedded switchable ferrimagnetic core and a coil that overlaps the switchable ferrimagnetic core. the switchable ferrimagnetic core may be operable in a first state where the switchable ferrimagnetic core is unsaturated. the switchable ferrimagnetic core may be operable in a second state where the switchable ferrimagnetic core is saturated by a magnetic field from a permanent magnet in a wireless power transmitting device. in the second state, the switchable ferrimagnetic core may have a lower magnetic permeability and higher magnetic reluctance than in the first state.
