After contacting Ragnar Tengstrand, the supervisor, I was determined to develop a baby carriage that will have a fan that gives cold during the summer period and a heat sink that will provide heat during the winter period. Only the frame of the stroller appeared within the delimitation of this project, but consideration was given to the location of the fan, powerbank, and the heat sink.

The work began with information searching for prams, competitors, medical visits and consumer interviews. Then a number of sketches were developed and were shown to the supervisor. From these terms, the one who was called "Product development of cooling/heating system for baby carriage" was chosen. This was further developed as well as CAD files, sketches and drawings were made for.
