AbstractThis course is offered by the Design and Technology Lab Zurich, a platform where students from the disciplines industrial design (ZHdK) and mechanical engineering (ETH) can learn, meet and perform projects together. In interdisciplinary teams the students develop a product by applying methods used in the different disciplines within the early stages of product development.
ObjectiveThis interdisciplinary course has the following learning objectives:
- to learn and apply methods of the early stages of product development from both fields: mechanical engineering and industrial design
- to use iterative and prototyping-based development (different types of prototypes and test scenarios)
- to run through a development process from product definition to final prototype and understand the mechanisms behind it
- to experience collaboration with the other discipline and learn how to approach and deal with any appearing challenge
- to understand and experience consequences which may result of decision taken within the development process
ContentAt the end of the course each team should present an innovative product concept which convinces from both, the technical as well as the design perspective. The product concept should be presented as functioning prototype.

The learning objectives will be reached with the following repeating cycle:
1) input lectures
The relevant theoretical basics will be taught in short lectures by different lecturers from both disciplines, mechanical engineering an industrial design. The focus is laid on methods, processes and principles of product development.
2) team development
The students work on their projects individually and apply the taught methods. At the same time, they will be coached and supported by mentors to pass through the product development process successfully.
3) presentation
Important milestones are presented and discussed during the course, thus allowing teams to learn from each other.
4) reflection
The students deepen their understanding of the new knowledge and learn from failures. This is especially important if different disciplines work together and use methods from both fields.

151-0516-00LNon-smooth DynamicsW5 credits5GC. Glocker
AbstractInequality problems in dynamics, in particular friction and impact problems with discontinuities in velocity and acceleration. Mechanical models of unilateral contacts, friction, sprag clutches, pre-stressed springs. Formulation by set-valued maps as normal cone inclusions and proximal point problems. Numerical time integration and Gauss-Seidel methods for inequalities.
ObjectiveThe lecture provides the students an introduction to modern methods for inequality problems in dynamics. The contents of the lecture are fitted to frictional contact problems in mechanics, but can be transferred to a large class of inequality problems in technical sciences. The purpose of the lecture is to acquaint the students with a consistent generalization of classical mechanics towards systems with discontinuities, and to make them familiar with inequalities treated as set-valued constitutive laws.

151-3206-00LSystemic Design for SustainabilityW4 credits3GT. Luthe
AbstractThis course introduces students to systemic design for sustainability to enable designers and engineers to take more effective action toward improving the complex sustainability challenges of today. Fundamental topics in systemic design cover the main theory, methods, and frameworks. Students will design and engineer their own outdoor sports product (e.g. a Surf-/Kite-/Skateboard).
ObjectiveThe growing necessity to consider eco-social aspects makes engineering design more complex. Systemic design combines systems thinking skills with design thinking to address such complexity. The objectives of the course are to introduce students to the most important topics in systemic design methods, models, theory and methodology that form the basis for engineering design practice and research for sustainability. A main goal is to develop whole systems thinking, life cycle and cradle to cradle thinking, to build knowledge on environmental impacts of materials and processes, and to stimulate overall reflective eco-social thinking in engineering design. Theory is applied by designing and engineering an individual outdoor sports product pushing the limits of systemic design for sustainability.
ContentThe course is organized in four units with a theoretical and a practical part : Unit 1) Create a self-reflective, in-depth understanding of sustainability in general and in specific relation with engineering design, Unit 2) Develop whole systems thinking and learn systemic design tools such as life cycle design, cradle to cradle design, upcycling, biomimicry, Unit 3) Understand the human behavioral factors within systemic design and sustainability impact assessment. Unit 4) Apply theory to practice and build your own Surf-/Kite-/Longboard according to the systemic design skills acquired during this course. Students will finish a sustainability impact study for ecological, social, technical and economic peformance indicators of the products they design and build.
