151-3201-00LStudies on Engineering DesignW+3 credits6AK. Shea, P. Ermanni, M. Meboldt
AbstractThis course introduces students to the exciting world of Engineering Design research, which crosses disciplines and requires a variety of skills. Each student identifies a topic in Engineering Design for further investigation, either based on those proposed or a new, agreed topic.
ObjectiveStudents gain their first knowledge of Engineering Design research and carry out their first, independent scientific study. Students learn how to read scientific literature and critically analyze and discuss them, gain hands-on experience in the area and learn how to document their work concisely through a report and short presentation.
ContentStudents identify 5-10 journal articles, or scientifically equivalent, in consultation with the supervisor and can define a small, related project in the area to gain hands-on experience. In the beginning of the semester, students develop with the supervisor a 2-page proposal outlining the objective of the study, tasks to be carried out and a brief time plan for the work. Once agreed, the project starts resulting in a report combining the state-of-art literature review and project results, if carried out.

The students work independently on a study of selected topics in the field of Engineering Design. They start with a selection of the topic, identify scientific papers for the literature research and can define a small, related project. The results (e.g. state-of-the-art literature review and small project results where defined) are evaluated with respect to predefined criteria.
Prerequisites / NoticeStudents take this course in parallel to the Lecture "Grand Challenges in Engineering Design". A general meeting will be held in the beginning of the semester to propose topics for the studies. Studies are carried out individually and can be the pre-study for a Bachelor thesis.

AbstractThis course introduces students to the practical application of integrative or systemic design by building their own skis or snowboards. Theroretical and applied Engineering Design skills like CAD, calculation and engineering of mechanical properties, 3D printing, laser cutting and practical handcrafting skills are trained and acquired in this course.
ObjectiveThe growing necessity to consider eco-social aspects makes engineering design more complex. Integrative or systemic design combines systems thinking skills with design thinking and practice to address such complexity. The objectives of the course are to use the practical ski/board building exercise to inhabit engineering design thinking and practice with a focus on the interplay between technical, social, ecological and economic aspects. The built skis/boards will be tested together out in the field on a ski day and evaluated from various perspectives. Students can keep their built skis/boards for themselves.
ContentThis practical ski/board building workshop will consist of planning, designing, engineering and building your own alpine or nordic ski, or a snowboard. Students will learn and execute all the needed steps in the building process, such as functional design, creating the CAD file, additive manufacturing techniques, fabrication, routing wood cores, 3D printing of plastic protectors, milling side walls from wood or ABS plastic, selecting fibres from carbon, glas, basalt or flax, laminating with resins, sanding and finishing, as well as laser engraving and veneer wood inlays. Experienced lecturers will be on site to teach and help with these tasks. Students are asked to eco-optimize their products, actively evaluate their learning and decision making process, and participate in a final ski test day on the snow.

AbstractThis course attempts to prepare the student for a job as a materials engineer in industry. The gap between fundamental materials science and the materials engineering of products should be bridged. The focus lies on the practical application of fundamental knowledge allowing the students to experience application related materials concepts with a strong emphasis on case-study mediated learning.
ObjectiveTeaching goals:

to learn how materials are selected for a specific application

to understand how materials around us are produced and manufactured

to understand the value chain from raw material to application

to be exposed to state of the art technologies for processing, joining and shaping

to be exposed to industry related materials issues and the corresponding language (terminology) and skills

to create an impression of how a job in industry "works", to improve the perception of the demands of a job in industry
ContentThis course is designed as a two semester class and the topics reflect the contents covered in both semesters.

Lectures and case studies encompass the following topics:

Strategic Materials (where do raw materials come from, who owns them, who owns the IP and can they be substituted)
Materials Selection (what is the optimal material (class) for a specific application)
Materials systems (subdivisions include all classical materials classes)
Joining (assembly)
Materials and process scaling (from nm to m and vice versa, from mg to tons)
Sustainable materials manufacturing (cradle to cradle) Recycling (Energy recovery)

After a general part of materials selection, critical materials and materials and design four parts consisting of polymers, metals, ceramics and coatings will be addressed.

In the fall semester the focus is on the general part, polymers and alloy case studies in metals. The course is accompanied by hands-on analysis projects on everyday materials.
