This report describes the degree project by Oscar Gustavsson and Sulaymon Valizoda during the spring term 2018 at School of Engineering in Jönköping. The thesis has been carried out for Husqvarna AB in cooperation with Semcon AB as a final part of the authors’ education to engineers in Mechanical Engineering, Product development and Design. Within the company Husqvarna AB development and renewal are of great interest. In their development of grass collectors, this mission was assigned where the goal was to create new concepts and solutions to a grass collector belonging to one of Husqvarna AB's existing walk behind lawn mowers. The aim was to reduce the amount of spilled grass that lands on the ground and making it easier for the user to empty the collector after the grass has been collected. The work has been carried out as a concept study where a selected product development process has been implemented. The different phases and methods of the process from pilot studyto prototype are described to clarify how their approaches have been used. During the project a requirement specification was defined which specifically described what would be fulfilled and which could be followed as a basis in the development of concepts. To give this thesis a theoretical background, theories about the product development process, computer-aided design, vacuum forming, steel and welding joints has been applied.The study resulted in a final concept that were further developed and prototyped. The concept was considered by Husqvarna AB to be the best concept to proceed with.Testing and evaluation were performed on the prototype where the work was limited to. Further more, Husqvarna AB is able to continue the development and use the information from the work, which hopefully can be a helpin the development of a better grass collector.
