Motorized Hot Pot Chopsticks with Rotating, Detachable Magnetic Tips

The problem

Hot pot and shabu-shabu are cooked at the table: each diner holds thin slices of meat or vegetables in boiling broth for a few seconds. According to the patent, the part of the food clamped between the chopstick tips is shielded from the broth, so food can be unevenly cooked unless the diner keeps turning it - a food-safety concern for meat and seafood.

The solution

1. The chopstick is an upper half (1) and a lower half (2) joined end to end into one slim rod - about 250 mm long in the patent’s example, similar to an ordinary chopstick.
2. The upper half is a hollow shell with a drive cavity. Inside is a reciprocating drive assembly (4): a battery tube (41) with a micro drive motor (42) at one end, a battery (43), a switch assembly (44) set into the outside face, and a protective cap (45) at the top holding a control board (46).
3. The motor turns a connector (3) at the lower end of the upper half. The lower half clips onto the connector and turns with it.
4. The switch assembly is two conductive rods (441) held by insulating rods (442), with several micro switches (443) side by side - so the motor starts wherever the diner’s fingers press.
5. The lower half is held by magnets in its end face and in the connector, and a key and groove align them.
6. Two charging pins (451) on the top cap, protected by a cover, charge the battery.

Who it is for

• Kitchen gadget brands looking for a hot pot or fondue accessory with a visible “it moves” demo.
• Asian tableware and hot pot supply companies selling to restaurants and home hot pot fans in North America.
• Hot pot restaurant chains wanting a signature table item or retail merchandise.
• Gift and novelty sellers for Lunar New Year, holiday and foodie gift seasons.

How it works

The main parts

Using it

1. Charge the chopsticks through the pins on the top cap.
2. Snap on the lower halves - the key lines them up and the magnets hold them.
3. Pick up a slice and hold it in the broth; squeezing the grip presses the switches.
4. The tips turn back and forth, moving the food so both faces meet the broth.
5. Pull off the lower halves after the meal and wash them; wipe the handles.

Where it is less suitable

• Everyday eating - for normal meals a plain chopstick is lighter and simpler.
• Dishwashers - only the detachable lower halves can be machine-washed; the handle holds electronics.
• Very low-cost restaurant use - a motorized utensil costs far more than disposable chopsticks.
