Requisites

Pre-requisite: MEC2301 or Students must be enrolled in one of the following Programs: GCEN or METC or GCNS or GDNS or MEPR or MENS

Overview

Most engineering products form part of a system which can be broken down into sub systems, assemblies, and components. A considerable amount of design synthesis and analysis must be done on the system as a whole before a product or process design specification can be drawn up. It is therefore important that the engineer can recognise what forms a system, a subsystem, and a component, and how the performance of the whole system is affected by the performance of its constituent parts.

In this course, the student engages in assignments and workshops to develop the student's ability to discern the relevant factors and design accordingly, to interact within a design team, and to communicate ideas and concepts through oral and written presentation. An essential skill for the design engineer is to be able to work across disciplines and therefore they often must "learn" new specialisations. In this course the student is introduced to several specialist topics not covered elsewhere in their course of study. This is a senior course, and it is assumed that the student has the maturity, knowledge, and skills base commensurate with having completed the first two years of their undergraduate course.

Course learning outcomes

The course objectives define the student learning outcomes for a course. On successful completion of this course, students should be able to:

  1. identify, review and evaluate design projects that require the system design approach;
  2. develop a design brief and plan and manage a system design;
  3. apply design principles, criteria and methods for a mechanical and mechatronic engineering design;
  4. optimise and rationalise a system design within an engineering framework, considering the statutes, ecology, common law, ergonomics, social acceptability, marketing etc that apply to engineering design processes;
  5. transfer and apply the use of appropriate computer techniques/packages;
  6. apply specialist knowledge and evaluative skills in a number of new areas within the discipline of mechanical engineering and mechatronic engineering;
  7. cooperate in a teamwork environment.

Student workload expectations

To do well in this subject, students are expected to commit approximately 10 hours per week including class contact hours, independent study, and all assessment tasks. If you are undertaking additional activities, which may include placements and residential schools, the weekly workload hours may vary.
