Aorogya setu App enhancement or alternate for slum areas (i.e. Dharavi, Mumbai)
While the app may help us fight Covid-19, it also has the very real potential to produce anti-democratic, exclusionary, discriminatory practices and structures at a larger scale.
At a time when the whole world is grappling with ways to contain the novel coronavirus, the Indian government is pushing its population to download the Aarogya Setu application to strengthen contact tracing and contain the epidemic. Contact tracing applications aim to track COVID-19 cases among citizens and surveillance is one of the key methods being utilized to track new cases and monitor the movement of people to record who they come in contact with.
Unlike other countries, the Aarogya Setu app also operates in a country where smartphone penetration is extremely low. According to a 2019 report by Pew Research Centre, smartphone penetration stands at a dismal 24% in India. 
So the challenge is to come with a solution for the development of alternate to Arogya setu or improvements on it. So the app can be usable in all devices instead of just smartphones.
Antiviral Drug development
Antiviral drugs are medicines that decrease the ability of flu viruses to reproduce. When used as directed, antiviral drugs may help reduce the duration of flu symptoms in otherwise healthy children and adults and may reduce the severity of common flu symptoms.
There are no Food and Drug Administration (FDA)-approved drugs for the treatment of COVID-19, although remdesivir, an investigational antiviral drug, is available through an FDA emergency use authorization. Definitive clinical trial data are needed to identify safe and effective treatments for COVID-19.
So the challenge is to come with a solution for development Antiviral Drug development which can help fight against the novel Corona Virus (COVID-19).
Build a solution to reduce the cost of ventilators
A ventilator is used when the breathing center of the brain is unable to control respiration. The machine resembles an octopus, with several pipes coming out of the main equipment. The additional pressure from the ventilator pumps oxygen into the bloodstream and takes out carbon dioxide from the lungs.
Hospitals are holding back from ordering more medical ventilators because of the high cost for what may be only a short-term spike in demand from the coronavirus epidemic, supply chain experts and health researchers say, intensifying an anticipated shortage of lifesaving equipment for patients who become critically ill.
On the other side, some patients need the ventilators in an emergency on their residences to save them from the sudden attacks and respiratory distress syndrome. But the cost and shortages, both are at the higher side so they cannot afford it.
So the challenge is to come with a solution for developing a solution to reduce the cost of ventilators and quick manufacturing processes.
Solar-powered automatic sanitizer and hand wash dispenser development.
The advancement of the automatic sanitizer dispenser further creates an even more sterile environment. When various individuals use the pump, they will leave behind a variety of bacterial colonies. These colonies will interbreed and lead to a more resistant strain of bacteria that can re-contaminate different hands and would not be eliminated by the anti-bacterial sanitizer. Wider spectra or higher levels of resistance, in the colonies that are present, are due to interaction and/or complementation between the resistance genes. Without having a wide variety of individuals touching the pump, the bacterial transmission will be eliminated.
Automated hand sanitizer dispensers had taken a huge market coverage to the communities. These machines work on basic programming concepts, some mechanical elements, sensors, and electricity. It can be installed at hospitals, vehicles, bus stations, police stations and public places
This constant supply-demand to the machine for its functionality is the question for its portability. Considering in open ground public areas like hospitals outdoors, big parking grounds, bus and railway stations, military bases, rural areas, forest areas and huge open lands.
So the challenge is to come with a solution for the development of Solar-powered automatic sanitizer and hand wash dispenser.
Herbal alternatives in front of allopathy and chemical integrated pharmaceuticals
​The current available chemical-based solutions are effectively working to fighting with novel Coronavirus but it may lead to some dangerous side effects that we can not ignore. Like the currently available Hand sanitizers and Hand washes lead to these risks:
Ingesting and inhaling sanitizer every day can increase your risk of alcohol poisoning

Abnormal Liver Function Tests
Backache
Chest Pain
Pain In The Arms Or Legs
Swelling Of The Abdomen
Vomiting
Behavioral Problems
Neuropsychiatric Disorder
But many types of research telling using herbs instead of chemicals can give only positive results without side-effects.
So the challenge is to come with a solution for developing Herbal alternatives in front of allopathy and chemical integrated pharmaceuticals to fight against COVID-19.
Social distances guiding gadgets
Because COVID-19 spreads from person to person, reducing the ways people come in close contact with each other is essential. Social distancing means staying home as much as possible and avoiding crowded, public places where close contact with others is likely.

After considering all these facts people still get intimation because of some careless reasons. The reason for that is people are not familiar with the new rules and these things are not in their Lifestyles. So, this may be harmful.
So the challenge is to come with a solution for the development of Social distances guiding gadgets that alerts people to keep some distance on every move.
Face touch prevention alert system
To help prevent infections, keep your hands away from your eyes, nose, and mouth. Why? Touching the mucous membranes on your face with your dirty hands allows germs that cause respiratory infections to enter the body.
Respiratory infections, like COVID-19, pneumonia or the flu, can spread through droplets in the air when a sick person coughs, sneezes, or talks near you. Respiratory infections can also spread by direct contact with bacteria, viruses, and other disease-causing germs. When we touch people who are sick or touch dirty surfaces, we contaminate our hands with germs. We can then infect ourselves with those germs by touching our faces.
It is estimated that people touch their faces about 23 times per hour! Respiratory infections can be caused by many different bacteria, viruses, and other disease-causing germs. When you touch your face with dirty, unwashed hands, germs can take up residence in your mucous membranes which can lead to an infection.
