| 151-0062-10L | Engineering Tool: Computer-Aided Design Methods  All Engineering Tools courses are for MAVT Bachelor’s degree students only. Number of participants limited to 25. | 0.4 credits | 1K | T. Stankovic, K. Shea | |||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | Participants will learn about the Computer-Aided Design fundamentals and methods that are necessary to model complex technical products. The focus will be placed on feature-based and parametric modelling that is common to all modern CAD tools used in mechanical engineering design. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Objective | CAD knowledge and skills will be further developed to enable students to recognize both the advantages and the limitations of current Computer-Aided Design tools. Examples of how to build feature-based and parametric models including design automation will be given along with common pitfalls. After taking the course students should be able to independently create effective feature-based and parametric models of mechanical parts. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Content | 1. CAD Methods and Feature-Based Design (2 afternoons): * CAD in the context of the design process * Feature types and their relation to mechanical design * Strategies for building feature-based assemblies * Integration of digital part libraries * Common issues and difficulties with feature interaction 2. CAD and Parametric Modeling (1 afternoon): * Designing and building parametric models * Design automation to create design variants * Common issues and difficulties with parametric modelling | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 151-0321-00L | Engineering Design and Material Selection | 4 credits | 4G | K. Shea | |||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | This course provides an introduction to engineering design. Through hands-on, practice-oriented exercises, students experience the fundamentals of design concept generation and selecting materials. They create 3D models in CAD for their own customized design and fabricate them using 3D printing. Three case studies in healthcare, mobility and sustainable materials will be explored. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Objective | The lecture and exercises teach the fundamentals of engineering design, drawing and CAD as well as additive manufacturing and material selection. After taking the course, students will be able to tackle simple design tasks, generate and evaluate concepts, accurately create technical drawings of parts and assemblies as well as read them. Students will also be able to create models of parts and assemblies in a 3D, feature-based CAD system. They will understand the links between engineering design and material selection, with a particular focus on sustainable materials, as well as additive manufacturing. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Content | Introduction to Engineering Design • design requirements • concept generation and selection • prototyping Design Representations • Sketching in Engineering Design • Technical Drawing: o projections, views and cuts o dimensioning o assemblies • CAD: o CAD modeling operations o parametric design and feature-based modeling o assemblies o creating 2D drawings from 3D part models Fabrication and Additive manufacturing Material Selection • materials and their properties, with special emphasis on sustainable materials • basic mechanics • material selection processes • testing material properties Three case studies in healthcare, mobility and sustainable materials | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 151-3209-00L | Engineering Design Optimization Number of participants limited to 60. | 4 credits | 4G | K. Shea, T. Stankovic | |||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | The course covers fundamentals of computational optimization methods in the context of engineering design. It develops skills to formally state and model engineering design tasks as optimization problems and select appropriate methods to solve them. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Objective | The lecture and exercises teach the fundamentals of optimization methods in the context of engineering design. After taking the course students will be able to express engineering design problems as formal optimization problems. Students will also be able to select and apply a suitable optimization method given the nature of the optimization model. They will understand the links between optimization and engineering design in order to design more efficient and performance optimized technical products. The exercises are MATLAB based. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Content | 1. Optimization modeling and theory 2. Unconstrained optimization methods 2. Constrained optimization methods - linear and non-linear 4. Direct search methods 5. Stochastic and evolutionary search methods 6. Multi-objective optimization | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 151-3213-00L | Integrative Ski Building Workshop Number of participants limited to 12. To apply, please send the following information to jchapuis@ethz.ch by 31.08.2022: Letter of Motivation (one page) , CV, Transcript of Records. | 4 credits | 9P | K. Shea | |||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | This course introduces students to engineering design and fabrication by building their own skis or snowboard. Theoretical and applied engineering design skills like CAD, analysis and engineering of mechanical properties, 3D printing, laser cutting and practical handcrafting skills are acquired in the course. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Objective | The objectives of the course are to use the practical ski/board design and building exercise to gain hands-on experience in design, mechanics and materials. A selection of sustainable materials are also used to introduce students to sustainable design. The built skis/board will be mechanically tested in the lab as well as together out in the field on a ski day and evaluated from various perspectives. Students can keep their personal built skis/boards after the course. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Content | This practical ski/board design and building workshop consists of planning, designing, engineering and building your own alpine ski or snowboard. Students learn and execute all the needed steps in the process, such as engineering design, CAD, material selection, analysis of the mechanical properties of a composite layup, fabrication, routing wood cores, 3D printing of plastic protectors, milling side walls from wood or ABS plastic, laying up the fibers from carbon, glas, basalt or flax, laminating with resins, sanding and finishing, as well as laser engraving and veneer wood inlays. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lecture notes | available on Moodle | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prerequisites / Notice | Willingness to engage in the practical building of your ski/board also beyond the course hours in the evening. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
