Smart Biowaste Machine

Riihimäki Mechanical Engineering and Production Technology Design of Mechanics Author Yijie Li Year 2015 Subject of Bachelor’s thesis Smart biowaste machine ABSTRACT The background for this thesis is mechanical design related to biowaste machine design and product development process. This machine should be able to pack food waste nicely for biogas generation. The topic was reuse of biowaste and the commissioner of this thesis was Nature resources education and research centre from HAMK University of Applied Sciences. The objective of this thesis work was: creating different ideas, an idea matrix, house of quality form making and the screening of idea method applying. The target of this thesis was to come up with a realistic and concrete solution of smart biowaste machine from customer needs. The project contained particular explanations of idea sketches or models, a particular introduction of an idea matrix, how the idea matrix was made, why the idea matrix and how to use the idea matrix. A House of quality form was also introduced in this project, with explanations on why it is useful, and the calculations behind this form. There are two idea screening methods introduced in this thesis. Mainly the idea screening method focused on how to calculate the results and select ideas according to the results. This thesis work is a product development process study and a process of mechanical idea generation, which are inseparable from customer needs. The final customer goal was to create a working prototype. Because of time issues, the thesis could not include a prototype, however, all the materials of this thesis work were handed out to the FUSA summer school student team as background support materials. Students from the team can use the existing ideas or upgrade the ideas and come up with better solutions. The final working prototype will be made by the summer student team.
