New Delhi; As per Ministry of Science and Technology, many S& T bases innovative solutions have been identified through the Challenge COVID-19 Competition (C3), by the National Innovative Foundation – India (NIF), an autonomous body of the Department of Science and Technology (DST).

The Challenge COVID-19 Competition (C3) was running from 31st March to 10th May 2020 for engaging innovative citizens to come up with ideas and innovations to tackle the pandemic.

NIF is providing incubation and mentoring support for further dissemination to the generator of the ideas. A foot-operated device for hand sanitization and washing and an innovative sprayer for sanitization are the two recently supported innovations under the campaign.



Shri Mupparapu Raju from Warrangal, Telangana, has designed thefoot-operated device (not operated by hands)for hand sanitization and washing, which is a timely solution in response to need for contactless devices in the prevailing COVID-19 environment. Both soap and water are stored in different containers.

Shri Raju has implemented the device at various locations (Warrangal, Mahabubabad, and others) in the State of Telangana. NIF has extended support to the innovator for value addition and in meeting the production commitments.

The other supported innovation is an innovative sprayer capable of sanitizing or washing large areas like roads, societies, doors, compounds, walls, etc. The sprayer consists of two radial fans of aluminum moving opposite to each other. In terms of mechanism, each fan sucks air from two opposite directions, which is released through nozzles at high pressure with minute droplets sizes.

As the panel rotates 180 degrees, it can cover from the ground upto 15 feet tall walls. Any tractor of power more than 15 horsepower(hp) can be used to operate this through Power Take-Off (PTO). By deploying this sprayer, one can sanitize the societies, roads, and so on at a maximum distance of 30 feet from the center of machine and upto 15 feet height. Which means the machine will sanitise 30 feet horizontally and 15 feet vertically.

As a result, compounds, doors can easily be sanitized with this sprayer. Nozzles in the sprayer are such that during operation of the device, the required area can be sanitized at ease, be it a spacious location or a congested location.

"Unleashing the partnership, ownership and creativity potential of our citizens in COVID-19 solutions and actions is a huge opportunity which is made visible by the NIF challenge. This is empowering our grass-roots innovators and entrepreneurs by recognition, prototyping help and thus translation of their relevant ideas into products.", said Prof Ashutosh Sharma, Secretary, DST.
