It’s 8 pm In Johannesburg on March 29, the first Sunday of the lockdown in South Africa, and a team from the University of the Witwatersrand (Wits) is hard at work, not in the comfort of their homes, but at an innovation lab, designing the first two prototypes of a face shield.
Letlotlo Phohole and Moses Mogotlane, the two members of the team, are working on paper and transparent face shield models, with a Perspex headband, and they are doing all of this at a Transnet-sponsored innovation space hosted at Wits; together in thought, but apart in (social) distance.
Their work would use 3D-printers and a laser-cut solution, in coming up with the very first version of a face shield developed by Wits.
Reeling from the disastrous effects of the Covid-19 pandemic, just like any other part of the world, Africa is turning to home-grown solutions such as this to tackle a global problem.
“Design can save the world,” says Dr Randall Paton, one of the engineers in charge of coordinating this project. And for any innovation at this time, speed is paramount.
“I think that innovation, especially of the sort that leaves us with a legacy of new products or ideas, is essential in tackling an issue like the coronavirus crisis,” he adds.
The face shields were initially designed for health workers at Netcare Hospitals, made from a flat pack consisting of two pieces that can rapidly be assembled.
Now, they are producing the face shields in only 90 seconds using die-cutting (cutting chosen shapes from low-strength materials), as opposed to 3D-printing them which takes up to 90 minutes.
