Winning industrial design came into play when South Korea’s Yakult yogurt company wanted a better pushcart for its 13,000 delivery ladies, who range in age from 20 to 60.

The carts go door-to-door daily because many in South Korea prefer their probiotic yogurt drinks delivered to their homes, in the same way milk was delivered to American homes during much of the last century.

The old Yakult push carts did little to ease the physical challenges of the door-to-door delivery job. So Yakult had Continuum redesign them into rugged, ergonomic carts that resemble walkers with wider wheels and a bar to lean on.

Yakult says its new cart enables workers to feel proud of their association with the Yakult brand and their important role in Korean daily life. The Yakult cart has been recognized by the Industrial Designers Society of America.
