Shimla, April 1

In a rare feat, a local lad from Fagu in the suburbs of Shimla, Piyush Chauhan, who is pursuing masters in computer designing, manufacturing and robotics from the Chandigarh University, has developed innovative devices in 3D printing, biomedical and automobile sectors and filed eight patents.

He has filed patents in all three categories — product, process and material — and his innovations include non-rotating card holder apparatus, liquid dispensing device for 3D printers, filament feeding device, vehicle occupant supporting apparatus, cloth drying apparatus, patient immobilisation apparatus, automobile defogging apparatus and fins straightening device.

“The patient immobilisation apparatus is useful for immunisation of small children under which vacuum is created in the buckles which restricts the movement of kids and helps in keeping the patient stable for injecting the injection,” he said.

The advantage of the modified design of liquid dispensing device for 3D printers is to help the issues of uneven and non-uniform spraying of material on a specimen, as material is sprayed using a pump and controlled by commands. The spraying is uniform while filament feeding device prevents the feedstock filament from stains and imperfect coating.

“My guide Dr Raman Kakkar at the Chandigarh University inspired me to file patents and the IPR Cell in the university taught us the method to proceed. The expenses of filing patents, which ranges between Rs 20,000 to Rs 50,000, were borne by the university,” he said.

Piyush (25) did his schooling from the SVM, Samoli, in Rohru and B.Tech in mechanical from Rajiv Gandhi Government Engineering College in Kangra.

A student of M.Tech final semester, Piyush, whose six articles have been published in international journals, wishes to pursue PhD in research after his post-graduation.
