300600 Mechatronic System Design

Question 1 DFMA:

In this question you are required to conduct a DFMA practice on a simple product – a ‘complex’ stationery (such as pen, hole punch, stapler, etc.) of at least 10 components which you have. The tasks include:

a) Disassemble the stationery, name its parts via taking photos to show them and create a Bill of Materials (BOM) for your pen;

b) Estimate its production/manufacturing costs cost; and

c) Through a disassembling and reassembly processing to identify the assembly process (the order of assembling and disassembling), calculate the assembling and disassembling time and assembly efficiency and indicate the difficulties on handling and insertion.

Question 2 DFE:

In this question you are required to conduct a DFE practice on pen investigated in Question 1. The tasks include:

a) List at least 10 types of environmental impacts over the life cycle of your covering Materials, Production, Distribution, Use and Recovery;

b) Suggest at least five ways to reduce its environmental impacts with the implementation of DFE design guidelines; and

c) Conduct a Qualitative Life Cycle Assessment (LCA) on the pen analysed using the template table from 3M.

Question 3 FMEA:

In this question you are required to perform a FMEA analysis based on the pen investigation in both

Questions 1 and 2 and the tasks include:

a) Identify EVERY Way in Which Part Can FAIL; i.e., determine the Failure MODES; and

b) Analyse the CONSEQUENCES of Every Failure; i.e., determine the EFFECTS.

The MS EXCEL Spreadsheet available in the vUWS site only shows you a template to generate an FEMA report. You may create the FEMA Report using a spreadsheet based on this one.
