Unit 6 Mechatronics - Higher National Certificate/Diploma in Mechanical Engineering
Learning Outcome 1: Examine the design and operational characteristics of a mechatronic system
Assignment Brief
LO1 Scenario pt1:
You have recently been interned by an appliance manufacturer Squeaky Clean as a mechatronic engineer.
Currently the manufacturer only produces timer-based washing machines. They to use modernize their product line by adding a fully automatic washing machines to remain competitive in the changing market.
You must prove to the chief engineer that you have the required knowledge to carry their company forward, by producing a report into how the system works and how the required components are to be integrated into the current product.
Q1 :
Produce an investigative report (with the aid of diagrams) of the Automatic washing Machine control system which includes:
1. Describing the key components on all the components (mechanical, electrical, electronic, and microcontrollers / microprocessors) required to operate the new automatic washing machine.
2. Identify the electrical/electronic sensors, transducers & actuator types used in the automatic
washing machine's system.
3. Explore how all the components in the automatic washing machine system operate as part of an integrated system. You are to include how the washing machines micro-processor uses the information from the various components to perform its action. Show how this system integration look like with the aid of a system flow diagram.
Scenario pt2:
Your initiative has paid off, and you are now working alongside the design team. You are now to show how the automatic washing machine system works at a mechatronic level.
Q2 :
Investigate the methods of control architecture used in an automatic washing machine. Describe what each method achieves in such a system via a written report.
Scenario pt3:
With the addition of Automatic washing machines to their product range, you have been mandated by the administration that the new system must be backward compatible with the old system, for ease and cost effective manufacturing.
Q3: D1
With the company seeking to move to fully automatic washing machines, make recommendations based on the current specifications on what changes may be required.
See the following table for the current timer based washing machine system specifications. Determine the components that are required, the systems specifications and propose an alternative solution in order to make the move towards automatic machines from timer based.
Based on the current timer washing machine spec, propose an alternative solution where necessary to make forward compatible with the new automatic washing system.
The System speciation are as follows:
