Unable to leave his apartment, he set to work in his spare room, creating prototypes for a product now known as “Sparshless” (sparsh means touch in Sanskrit).

The system consists of a panel that is fitted alongside existing elevator buttons. It allows users to select a floor by pointing their finger at each button from a distance of 10 to 15 millimeters (0.4 to 0.6 inches), triggering an infrared signal which tells the elevators where they want to go.

Sparshless units are also mounted at elevator entrances on each floor, says Ahir. Users place their hands under the arrows on the unit to indicate whether they want to travel up or down.

It’s a completely contactless system designed for a world where people have become cautious about everything they touch.

Dirtier than a toilet seat

In India, Ahir sought more sophisticated technology.

Making the product

Ahir usually works from his company’s office in the city of Surat, where he employs 12 permanent staff. The 31-year-old entrepreneur started his business, TechMax Solution, in 2009, straight after graduating from college. The company’s key products are security devices, but during India’s four-month lockdown, work dried up. During that time “we didn’t raise even one rupee,” he says.

Ahir responded to the crisis by developing the Sparshless system, testing the first prototypes on his neighbors. Early models were adjusted when he discovered that daylight triggered false readings. The system also needed to be installed in such a way that it didn’t affect the elevators’ normal workings — or warranty.

With those problems solved, the next step was finding customers. That hasn’t been easy during a nationwide lockdown, says Ahir, but so far, the units have been fitted in 15 buildings in India.

Sumit and Sushila Katariya live in one of those buildings. Sumit is an elevator consultant, and Sushila is a doctor at Medanta Hospital, southwest of Delhi, who has treated hundreds of coronavirus patients since March.

Sumit Katariya had the touchless buttons installed in the personal elevator at his two-story housing complex to reduce the risk of this wife infecting the family and their visitors, if she caught the virus. He says the panel has been working “perfectly fine” since they had it installed about one month ago.

Ahir says he has received inquiries from Kuwait, the United Arab Emirates and Brazil about the panels. He hopes to sell up to 1,500 units by the end of the year, an ambitious target for a small company with one manufacturing facility in the country with the world’s third highest number of coronavirus cases.

It’s a “tough situation” he says, but “I always think positive.”
