Have you ever thought about where new designs come from? How was the first computer designed? What about the first car?
If you've sat in design and technology lessons trying to come up with design ideas, you'll know how hard it is to be completely original. Very few people, if anyone, suddenly think of something completely new. All of the designs that surround you at the moment, from furniture and products to clothes and fabrics, have been inspired by something else.
Designers usually look at existing products and consider how they could be improved or used in a different way. They might take apart a product, or look at detailed plans and diagrams to see how they could be changed.
This case study tells the story of George Omondi, an innovator in Kenya who modified and improved an existing design for a peanut butter mill.
