This thesis presents the process of designing a handheld olive harvesting machine. It consists of firstly recognizing user needs and market conditions. Secondly, creating technical specifications of the device using the quality function deployment method. Then, generating concepts using functional decomposition and morphological matrix. After choosing the best concept, it was further elaborated by choosing the components that will be bought and designing those which will not. The resulting product is powered by a 113 W electric motor and is capable of harvesting 40 kg of olive fruit in one hour. 3D CAD model and technical documentation were created in Solidworks 2020 software.
