Course Objectives

In this course, students will gain hands-on, practical experience applying engineering principles, theories, thought processes, and problem-solving approaches to the design and prototyping of a physical product. Students will develop skills for working in teams, working with open-ended problems, and making appropriate engineering assumptions. Students are expected to research the topic area, identify opportunities and design criteria, generate creative concepts, synthesize detailed design of the concept, analyze the design on a number of criteria to make improvements, and prototype and communicate the final solution.

While most courses in the mechanical engineering curriculum focus on structured transfer of theoretical knowledge in analysis of mechanical phenomena, this course aims to provide students with a chance to build complimentary experiential knowledge in application and synthesis. Topics covered include design process, project planning, product dissection, design for manufacturing and assembly, engineering ethics, failure mode and effects analysis, life cycle assessment, design for environment, market research, concept generation and concept selection techniques, quality function deployment, intellectual property, detailed design, engineering drawings, prototyping, professional communication, design optimization, machine component design, and engineering economics.

Learning to design is a bit like learning to write. It is not the case that you will enter the course without knowing how to design and exit the course knowing the formula for design. Like writing, there is typically no unique “right” answer in design – but some answers are better than others, and some are more well-justified than others. You will learn through experience, feedback, interaction, failure, and iteration about how to conduct a more robust, thoughtful, systematic, and objective-focused process for making decisions and justifying those decisions through analysis in the design and development of an engineered product.
