Design Engineering Lab
Machine-translated · View original
An engineering education lab that uses 3D printers to turn the machines students design into physical objects.
AboutAbout the lab
Turning design results into something you can see.
In this lab, Lecturer Keiichiro Takato studied how to develop teaching materials that turn what students design in mechanical design courses into something visible.
The aim was to make the whole process a PBL topic: for a problem that differs from student to student, conceiving, designing, and building based on numerical evidence, and then evaluating the performance of the finished product.
Using a 3D printer, the lab turned the gear transmission assigned in mechanical design and drafting into a working model, including a synchronizer mechanism that allows gear changes.
In the department's faculty list, his fields of specialty are given as design engineering, engineering education, and flow visualization.
Key terms
- PBL
- A form of class in which students learn while working on a task. Here, the whole process from conception through design and building to performance evaluation is carried out as one continuous flow.
- Synchronizer mechanism
- A mechanism that allows gears to be changed even while rotational force (torque) is being transmitted
ResearchResearch themes
The lab studied how to create engineering education materials that let students actually build what they design in class and check its performance. It reworked assignments in mechanical design and drafting, and studied a method of building them with a 3D printer and evaluating them.
*Illustrative imageDesign assignment for rotating machinery
The lab studied reworking the centrifugal pump assignment in design drafting so that students can go from creating a model in 3D CAD to building the actual object. It also considered alternative topics: an air-driven blower, a bamboo-copter, and a Stirling engine for observing heat exchange.
*Illustrative imageBuilding a model of a gear transmission
The lab studied making the gear transmission assignment in design drafting into a working model with a 3D printer. It also modeled a synchronizer mechanism that can change gears while transmitting torque, and worked on verifying whether it produces an educational effect. Based on the results of shape measurement and strength tests, it also proposed a method of evaluating part quality with machine learning.
