A study on monozukuri education in karakuri doll production

Abstract

We are practicing Monozukuri education focusing on practical fields based on the subjects of mechanical engineering, in the Department of Products Design, at the College of Industrial Technology. Students can learn not only theoretical learning but also subjects related to practical training such as processing, product design, and design. Karakuri doll production, which is one of the themes of exercise, is reproduction of Karakuri doll depicted in the illustrated “Karakuri Zui” (1796), the guide to mechanical devices from the Edo Period. “Karakuri Zui” is an enlightenment book of the machine technology and can read in National Diet Library, and Karakuri doll and Karakuri clock are listed. In graduation research, students deepen the knowledge necessary for Karakuri doll production from Karakuri Zui and other literature, determine Karakuri doll that production to. Karakuri doll is a tea carrying doll that students decided to produce. It approaches guests carrying a cup of tea and clears away the empty teacup. Students plan Karakuri doll using 2-Dimension and 3-Dimension CAD software. In 2-Dimension CAD software, data for laser cutter is created, and in 3-Dimension CAD software, assemblies are checked for errors by 3D assembly. Figure 1 shows plan Karakuri doll by 2-Dimension and 3-Dimension CAD software. Students produced Karakuri doll using various tools such as laser cutters and lathes. Through Karakuri doll production, students were able to acquire various knowledge about Monozukuri. In this paper, we report on Monozukuri education in Karakuri doll production using these methods.
