# Undergraduate Course: Mechanical Design Principles 3 (MECE09018)

 School School of Engineering College College of Science and Engineering Credit level (Normal year taken) SCQF Level 9 (Year 3 Undergraduate) Availability Available to all students SCQF Credits 10 ECTS Credits 5 Summary Engineering 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. Course description Course Syllabus: Unit 1 - Course Overview 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. Unit 8 - Taguchi Methods Fractional Factorial Experiments; Linear Graphs; Confounding. Unit 9 - Orthogonal Arrays Parameter selection; Interpretation of Results. Unit 10 - Material Properties and Failure Static Strength; Stiffness; Brittleness; Resilience; Toughness; Creep. Unit 11 - Stress Concentration Design for Static Strength. Unit 12 - Fatigue Failure Terminology; Measurement; Characteristic Curves; Miner's Rule; S-N Curves. Unit 13 - Reliability Reliability in the design specification; Cost of reliability. Unit 14 - Component Failure Reliability of an assembly. Unit 15 - Tools for Exploring Failure of a Design Fault tress; Failure Modes and Effects Analysis

 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.
