The Smart Mug That Keeps Your Coffee Hot Without a Microwave

Imagine a coffee mug with built-in heating elements powered wirelessly—no plug needed. Sensors inside monitor your drink's temperature and automatically heat it to whatever warmth you set on your phone, keeping your coffee perfect for hours.

The plain-English version

What it protects

The claim covers a mug or travel mug with an integrated heating system that includes heating elements, wireless power receivers, rechargeable energy storage, temperature sensors, and control circuitry that automatically maintains a user-selected temperature. What's protected is the combination of these heated-mug components working together—the wireless charging capability, the sensor feedback loop, and the automatic temperature regulation system that keeps liquid at a constant warmth without manual intervention.

Why it matters

This patent protects a solution to an everyday problem: beverages cooling down while you're distracted. By combining wireless charging with smart temperature sensors and automated heating, it creates a category of self-heating drinkware that could appeal to commuters, office workers, and anyone frustrated with lukewarm coffee. The wireless power element is particularly valuable because it eliminates the need for built-in batteries or plug-in cords, making the mug practical and portable.

Real-world use

A commuter places their mug on a special charging mat at their desk, sets the temperature to 150°F via their phone, and their coffee stays perfectly warm through a two-hour meeting without reheating.

Original USPTO abstract

An actively heated mug or travel mug is provided. The mug or travel mug can include a body that receives a liquid therein and a heating system at least partially disposed in the body. The heating system can include one or more heating elements that heat a surface of the receiving portion of the body and one or more energy storage devices. The mug or travel mug can include a wireless power receiver that wirelessly receives power from a power source and control circuitry configured to charge one or more power storage elements and to control the delivery of electricity from the one or more power storage elements to the one or more heating elements. The mug or travel mug also can have one or more sensors that sense a parameter of the liquid or sense a parameter of the heating system and communicates the sensed information to the control circuitry. The control circuitry can turn on, turn off, and/or operate the heating element to actively heat at least a portion of the body to maintain the liquid in a heated state generally at a user selected temperature setting based at least in part on the sensed parameter information. The mug or travel mug can also be paired with a remote device or mobile electronic device to send or receive communications or commands.
