The essay is a thesis of 15 credits in the product design program at Malmö University. The project manages diapers design with a resulting suggestion on how this product can be improved, with a specialization in sustainable development. The result was a diaper with inserts, for the more unconscious buyer, which reduces the number of changes and consequently the amount of eco-wracking materials needed to be manufactured and disposed In the focus area Olof Kolte, prominent industrial designer working with sustainable development, was interviewed and a literature search was conducted in the area. The preliminary investigation regarding diapers were based primarily on qualitative interviews, and the conceptualization was based primarily on a number of brainstorms and a method called the backward method, developed by Edward de Bono, author and consultant in lateral thinking.
