There is a trend toward increasing exposure of students to hands-on experience in mechanical engineering design courses as these courses are usually limited to generating calculations and drawings of mechanical designs. Students in these courses may lack the ability to visualize and create the physical objects that correspond to their calculations. This limitation may negatively affect students, especially those with limited hands-on experience. To address this issue, the Department of Mechanical Engineering, University of Nevada, Las Vegas (UNLV) started requiring students to create their design using a rapid prototyping machine as a part of the Mechanical Engineering Design Course (ME 440). Students in this course work in teams to create projects starting from abstract statements. They are required to use their calculations as a means to create solid models of the components of their designs and print them on the rapid prototyping machine. Such an approach results in a better understanding of the functionalities of components as well as fit and tolerance issues. Student feedback is used as well as future venues for improving the course.

AbstractHardly any other area has as much disruptive potential as digital platforms in the course of digitalization. After serious changes have already taken place in the B2C sector with platforms such as Amazon and Airbnb, the B2B sector is on the threshold to the so-called platform economy. In mechanical engineering, pioneers like GE (PREDIX) and Claas (365FarmNet) are trying to get their hands on the act. This is hardly a promising option for small and medium-sized companies, as only a few large companies will survive. Small and medium-sized enterprises (SMEs) are already facing the threat of losing direct consumer contact and becoming exchangeable executers. In order to prevent this, it is important to anticipate at an early stage which strategic options exist for the future platform economy and which adjustments to the product program should already be initiated today. Basically, medium-sized companies in particular lack a strategy for an advantageous entry into the future platform economy.The paper presents different approaches to master the challenges of participating in the platform economy by using platform patterns. Platform patterns represent proven principles of already existing platforms. We show how we derived a catalogue with 37 identified platform patterns. The catalogue has a generic design and can be customized for a specific use case. The versatility of the catalogue is underlined by three possible applications: (1) platform ideation, (2) platform development, and (3) platform characterization.
