On completion of this course, the student will be able to:
- Describe: - The main stages of the design process within the context of commercial product design: from the recognition of 'need' through to production. Including the interaction between company functions such as marketing, production and maintenance etc. - 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.
- Demonstrate: - An awareness of some of the material properties associated with component failure. - How to select a suitably sized experimental matrix for use in the design of experiments and designate columns for main and combined effects using linear graphs.
- Use: - Requirement trees to explore and define the constraints and requirements of a system given a simple design specification. - 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. - Basic probability theory to predict the reliability of design systems where components may be deployed in series or parallel and the effects of redundant systems.
- Calculate: - The fatigue life of simple component geometries subject to varying loads.
- Interrogate: - Designs for likely causes of failure using both top-down fault tree analysis and bottom-up failure modes and effects analysis.
