An education method for mechanical design is discussed. In conventional design education, the prototype designs together with design process are given for students, which can be referred to as parameterized design. This is a good introduction for students to start the design class. However, the big picture of the design process could not be learned. For students to experience total design paradigm, a design seminar has been opened every summer in past decade. We discuss the pros and cons of the current seminar and present the perspective of next turn.
