A common source of concern for designers at the beginning of their careers is the factors that need to be determined on the basis of experience and a sense of balance as designers. Such factors are no obstacle to experienced designers. However, no matter how much young designers think about those factors, they cannot arrive at the solution. As a result, they can pose only very simple questions about such factors. To create new machines, knowledge of kinematics becomes necessary. Furthermore, to create better machines, a crucial aspect is the development of design sensibility. Design sensibility in this context refers to the ability to incorporate balanced motion and force without unnecessary complexities on the basis of a combination of extensive knowledge and experience with mechanisms. In this paper, we reaffirmed mechanism design as one of the fundamentals of mechanical design principles. We examined the content that young designers can effectively apply, for example, basic approaches that enable the rapid ideation of various mechanisms, when engaged in mechanism design, especially in advancing new product designs. In addition, we developed training materials that present practical examples for learning.
