Title:
ELECTRONIC DEVICE FOR PREVENTING SPILLING OF LIQUID DURING MOVEMENT
Document Type and Number:
WIPO Patent Application WO/2020/235825
Kind Code:
A1
Abstract:
An electronic device is disclosed. The electronic device comprises: a container; a sensor; a drive unit; and a processor for inputting a drive signal into the drive unit so as to control the speed of the electronic device. The processor: measures at each time interval, on the basis of sensing data received through the sensor, external forces applied to the electronic device from the ground on which the electronic device is located, while the electronic device moves; identifies, on the basis of frequency characteristics of the external forces measured at each time interval and the natural frequency of a liquid contained in the container, an element having frequency characteristics corresponding to the natural frequency from among the external forces; and inputs into the drive unit, on the basis of the size of the identified element, a drive signal which enables the speed of the electronic device to change according to the natural period of the liquid.
