MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202621006470 A) filed by St. Vincent Pallotti College Of Engineering And Technology, Nagpur, Maharashtra, on Jan. 22, for 'an active dynamic vibration absorber system for vibrating household appliances.'
Inventor(s) include Amit Ramesh Bhende.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an active dynamic vibration absorber system for reducing vibration in washing machines and similar household appliances. The system comprises a washing machine drum (101) acting as a primary vibrating structure, at least one vibration sensor mounted on the drum (101) or cabinet to detect vibration levels, and a microcontroller (102) configured to receive and process vibration signals. A control algorithm module (103) executed by the microcontroller (102) computes a compensatory control signal in real time based on sensed vibration. An actuator driver (104) amplifies the control signal and drives an active absorber (105) comprising an electromechanical actuator coupled with a movable mass. The active absorber (105) applies a counteracting force that is substantially out of phase with vibration of the drum (101), thereby reducing vibration transmitted to the cabinet and floor. A power supply (106) provides regulated electrical power to all system components. The system operates in a closed-loop configuration, enabling adaptive vibration suppression across varying operating speeds and load conditions, offering improved performance over conventional passive vibration control system."
