Lwazi Grant, a third year Industrial Design student’s invention, the “Dula-Coola”, has won him a cash prize of R50 000 in the Tshwane University of Technology’s annual innovation competition. 

The twenty three year old Grant had the judges captivated by his powers of invention and saw him taking the overall prize at this year’s Innovation Competition Awards ceremony.

Dula-Coola is a proudly South African designed version of a cooler box. Dula, meaning to sit in Sesotho, is what makes the name of the cooler box so unique.

“Many people can relate to this. Whenever I would go to festivals and outdoor picnics, I took a cooler box and a camp chair. At times other people would end up sitting on the cooler box, as a result, it would break or deform in shape. That’s when I got the idea of simplifying the use of a cooler box and camp chair into one new product,” explains Grant.

The second prize of R40 000 went to Sizwe Nxumalo and Sibusiso Mahlangu for their Electrostatic Duct Dust Precipitator invention. Thabiso Matenchi came third for his Smart Water Meter invention and took home R30 000 in cash.
