Technology developed: Floor stone polishing device (TP19763280793)
Category: Nil
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Susmita Nath, Sougata Karmakar and Rajiv Tiwari Indian Institute of Technology Guwahati DESIGN Research scholar, Associate Professor and Professor
Technical Application Area: Civil Engineering
If 'Other', please specify:

Please give more details of new technical application area:
The devloped device is suitable for polishing the surface of the stone or floor made up of stonne or mosaic in the construction sector
Indian Institute of Technology (IIT) Guwahati
Affiliated Ministry: Ministry of Education
Type of technology development: Indigenous
Does the technology help in replacing any import items currently
procured from outside India?
Does the technology have export potential? Yes
Category of Technology developed: Immediate Deployment
Stage of Development: Prototype Level
Please describe in detail including the TRL Level:
The prototype of the redesgned floor stone polishing machine has been developed and field tested for demonstrating its better efficiency and usability Users are highly satisfied with the redesigned device as evident from Filing patent and design registration are under process


Applications: Workers engaged in stone floor polishing activities suffer from work-related musculoskeletal disorders WMSDs due to exposure to high level of hand arm vibration adopting awkward postures and performing strenuous repetitive activities for prolong duration Polishing tools available in the local market and used by the construction workers are mainly the modified drill machines It has various limitations which include generation of huge vibrational energy due to torque and jerk by a compound gear mechanism improper handle design in terms of grip diameter coating material form etc the requirement of high muscle force for polishing and sustained load holding To resolve the aforesaid lacunae an ergonomic redesign of the polishing machine has been carried out Field trial of the developed prototype II was highly appreciated by the user
Advantages: less vibration generation and transmission due to planetary gear mechanism and use of vibration dampening coating material on handle supportive legs to avoid sustained load holding along with provision of two hand manoeuvrability less muscle force for polishing operation AND anthropometric compatible handle and aesthetic look

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
