MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202641074369 A) filed by J. J. College Of Engineering And Technology on June 16, 2026, for Adaptive Vibration Isolation Handle With Grip-Force Coupled Pneumatic Damping For Handheld Industrial Tools.
Inventors include Dr. M. Sreearravind; and Dr. P. Mathiyalagan.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: An adaptive vibration isolation handle for handheld industrial tools is disclosed. The handle is configured to be retrofitted onto existing tool handle shafts having varying diameters. The system includes a clamping module for tool mounting, an ergonomic grip module built in with sensors used to measure operator grip force, a pneumatic damping module placed between the clamp and the grip, and a control module for regulation of pressure within the pneumatic damping module. The damping module includes a pressure-controlled pneumatic chamber located between the central support column and the outer grip. The control module includes a microcontroller, a pressure sensor, a miniature air pump, and a control valve to regulate air pressure inside the pneumatic chamber. During the operation, grip force from the operator hand is consistently transmitted to the control module, in response to the grip force, control module adjusting the pneumatic chamber pressure to modify the vibration isolation characteristics of the handle. This active closed-loop system adapts damping characteristics during tool operation, and resulting in the reduction of transmission of vibration from the tool to the operator’s hands and helping to reduce the health hazard related to prolonged vibration exposure.
