SummaryEngineering design is often regarded as the central creative activity of engineering, requiring the skills of analysis and synthesis to develop solutions to open-ended problems. This module consolidates and builds on students' existing design experiences.

Introduction; The Design Process; The Process model.
Unit 2 - Design Requirements
Identification of Design need; Product Life Cycle; Legislative constraints.
Unit 3 - Design Definition
Exploring the design requirement through the use of "Requirement Trees"; Product Design Specification.
Unit 4 - Creativity
Creative style; Divergent/Convergent Thinking; Brainstorming; Morphological Analysis; Creative Habits.
Unit 5 - Problem Solving
Engineering approximations and assumptions.
Unit 6 - Embodiment and Detail design
Preferred Number Series; Standard sizes; Guidelines for good embodiment design.
Unit 7 - Design of Experiments
Factorial Experiments; Limitations of Factorial DOE.

Learning Outcomes
On completion of the course, the students should be able to:
1. Describe, within the context of commercial product design, the main stages of the design process: from the recognition of 'need' through to production. Including the interaction between company functions such as marketing, production and maintenance etc.
2. Use requirement trees to explore and define the constraints and requirements of a system given a simple design specification.
3. Explain differences in creative 'styles' and some of the thought processes involved in design, including the notion of convergent-divergent thinking, and how these styles can be exploited through the use of creativity tools such as brainstorming and morphological analysis.
4. Select a suitably sized experimental matrix for use in the design of experiments and designate columns for main and combined effects using linear graphs.
5. Carry out simple statistical analysis on the results of full and partial factorial experimental designs and use this data to derive simple predictive models of multi-parameter systems.
6. Demonstrate an awareness of some of the material properties associated with component failure.
7. Calculate the fatigue life of simple component geometries subject to varying loads.
8. Use simple probability theory to predict the reliability of design systems where components may be deployed in series or parallel and the effects of redundant systems.
9. Interrogate designs for likely causes of failure using both top-down fault tree analysis and bottom-up failure modes and effects analysis.
