This course introduces core concepts in mechanical engineering design, equipping students with the foundational knowledge and practical skills needed for interdisciplinary and international design projects. Key themes include the engineering design process, technical drawing and visualization, mechanical decision-making, and material selection with sustainability in focus. Through a mix of lectures, hands-on drawing sessions, case analysis, and preparatory design work, students develop the competencies to contribute meaningfully to the TED School mechanical design project. The course also prepares students for further CAD-based modeling and prototyping tasks.
