The Mechanical Engineering Department at the California State University at Northridge has adopted the Conceive-Design-Implement-Operate (CDIO) framework as the overall guiding philosophy in reforming its undergraduate education. An important standard to achieve in this adoption is to have several design-build project experiences in the curriculum. To spearhead this effort, one of two sessions of a sophomore design course that teaches mechanical design for manufacturing was chosen as an experimental session and was redesigned to teach a project involving designing and building yoyos, along with CDIO, personal, and interpersonal skills. Student teams go through the complete product development cycle (i.e., four phases of CDIO): conceiving innovative ideas and concepts; designing and reiterating concepts of yoyos to meet  requirements; implementing the concepts and manufacturing yoyos; and operating the yoyos in the context of safety and a yoyo-trick contest at the end of the semester. Engaging in the project helps students become proficient in using Computer Aided design/Manufacturing tools and machines (e.g., SolidWorks, Esprit, Rapid Prototyping, Injection Molding, and Computer Numeric Control machines); internalize the role of key manufacturing metrics in modern manufacturing systems; and learn personal, interpersonal, and professional skills. Results obtained through self-reporting surveys and performances on a design problem given to students in both sessions show that teaching the design-build project significantly improves students’ ability to conceive and design a product and to work in a team-based environment. The improvement in the students’ learning has resulted in adopting a design build project in all future sessions of this course. A plan for integrating this course with other core design courses, and into the Department overall plan for adopting CDIO is also discussed.
