The Wireless Heating Pad That Charges Without a Cord
Imagine a heating pad that charges wirelessly, like your phone on a charging mat. Instead of plugging into a wall socket, it sits on a wireless charging device that beams power to it through the air. It stores that power in a rechargeable battery and uses it to generate heat whenever you need it.
The plain-English version
What it protects
The claim covers a heating pad design that includes three key parts working together: a receiver circuit with a built-in rechargeable battery, a heating element connected to that battery, and a pad body that holds everything. What's protected here is the specific way these components are assembled and how the pad physically attaches to furniture or clothing through a removable mounting system, allowing it to be charged wirelessly by an external charging device.
Why it matters
This patent addresses a real consumer frustration: heating pads come tangled with cords and are often bulky or unsafe to use in bed. By combining wireless charging technology with thermal comfort, the design opens up new possibilities for heated furniture, clothing inserts, and medical devices. The removable attachment means one pad could theoretically work with multiple articles, making the technology more versatile and appealing to manufacturers looking to add heating capability to existing products without major redesign.
Real-world use
You'd encounter this in a heated car seat that charges overnight on a wireless dock, or a heated throw blanket that slots onto your couch's charging frame without any visible cords.
Original USPTO abstract
The present invention provides a wirelessly-chargeable heating pad, which is coupled to an article in a removable manner and is used in combination with a charging device to perform wireless electrical charging. The wirelessly-chargeable heating pad includes a receiver circuit, a heating element, and a pad body. The receiver circuit includes a rechargeable battery. The heating element is electrically connected to the rechargeable battery. The heating element and the receiver circuit are both mounted to the pad body. The article includes a removable mounting structure, so that the wirelessly-chargeable heating pad is removably coupled to the article through the removable mounting structure. The charging device, after receiving electrical power, converts the electrical power into an alternate current signal that is transmitted to the receiver circuit. The receiver circuit receives and converts the alternate current signal into electrical power that is then stored in the rechargeable battery. The rechargeable battery subsequently supplies the electrical power to the heating element to give off heat.
