Abstract [en]

Two students from the school of engineering in Jönköping has during the spring semester of 2018 performed a bachelor thesis. The thesis was performed in cooperation with Greenworks Tools in Jönköping.

The purpose of this thesis is to establish an understanding of the technical aspects of a hedge trimmer and the product development process. During this thesis, the students will generate and evaluate different concepts for a new gearing system. The study investigates if it is possible to rotate the motor in one of Greenworks hedge trimmers 90±15°along the cutting direction, without deteriorating the hedge trimmer´s performance or ergonomical propperties.

The main limitation for the thesis is that exclusively the motor gear and the connection to the gearbox can be changed.

To answere the thesis problem different kinds of methods and tools were used. A few of the implemented methods used during the thesis are product development process, QFD and Pugh’s matrix, to verify the concepts Cad simulations and calculations were established.

The result of the study shows that it is possible to rotate the motor without detoriating the hedge trimmers preformance with respect to the given information. The thesis study generates a basis for further development and for future products.
