abstract: Part visualization is a fundamental skill in engineering. It comprises the reading, interpretation and creation of industrial technical drawings. However, engineering students show certain learning difficulties and a high failure rate in subjects such as Technical Drawing and Design. A problem solving model for visualization has first been designed and developed for all kind of industrial objectswithin a constructivist framework. The Problem Solving model is the key to all technical knowledge and is an application of the scientific method. To develop this methodology, technical drawing textbooks, research and papers from all around the world have been used. In relation with this methodology, some teaching strategies have been developed. They may be applied by drawing up a programme of specific tasks which takes into account the theoretical contents and procedures involved in part visualization as well as the students? main difficulties and deficiencies when faced with this kind of problem. The main aim of this paper is to show, reason out and discuss this new methodology for part visualization.

Flowchart-Assisted Function Analysis of Products to Support Teaching of the Exact Sciences

van der Vegte, Wilhelm Frederik; van Breemen, Ernest JJ • 2009

abstract: To reintroduce function analysis (FA) into the curriculum of Industrial Design Engineering, we developed a systematic approach for interaction-intensive products. By strengthening the link between high-level design considerations and exact-science-based engineering calculations, we intended to overcome the lack of commitment of our students to the exact sciences. We found that conventional FA approaches are difficult to apply to products interacting with users, while the user-oriented approaches that have come to replace FA in our curriculum hardly connect to engineering aspects. The new approach involves a procedure to extract functions from the process tree that is commonly used in design projects, and which allows mapping of transformations performed by the user to functions of the product. Putting functions on a gradual scale from "good" to "bad" gives directions for reconsideration. The approach is "open" and allows combining with related other methods. It was embedded into a new engineering-oriented course. Evaluation showed that the new course succeeds in more effectively communicating the relevance of exact sciences. Future plans include application in design projects.

Virtual Product Development Study Courses Evolution and Reflections

Zavbi, Roman; Kolsek, Tomaz; Duhovnik, Joze • 2009

abstract: The product development teams become organizationally, geographically and culturally dispersed over the globe. The strategic alliance of several European universities has formed an "E-GPR" (European Global Product Realization) study course as a response to the product development challenges. The effective means for long-distance communication enabled intensive collaboration between competitive student teams. The industrial partners provided the project tasks to be solved within a short one semester time and required functional prototypes. We describe the setup of the course, the results, and provide some reflections. The course evolved during its repetitions over 7 consecutive years. The project work has been thoroughly monitored and the results have been assessed and quantified. The students should gain valuable experience in communication, organization, public presentation of work and prototyping and thus should better be prepared to tackle challenges associated with working in contemporary companies operating in a fierce business environment.

University of Niš as a Supraregional Academic Education Center for Product Development in South East Europe

Albers, Albert; Norbert, Burkardt; Claudia, Becke • 2009

abstract: After the war in former Yugoslavia stability and academic education needed to be reconstructed. This is focused by the DAAD program "Academic Reconstruction South East Europe". It is financed within the Stability Pact for South East Europe. A cooperation between the University Karlsruhe (TH) and 8 universities in South East Europe was founded. To reconstruct and to improve the curricula a joint education module on Product Development based on the Karlsruhe Education Model for Product Development (KaLeP) was created. At University Nis in Serbia a supraregional center for product development was built: Machines Development and Construction Center (CERP). It fits the needs of a curriculum according KaLeP and it supports the integration of project work into academic education leading to a development of key competencies of future engineers. CERP has team workspaces for students to ensure a realistic working environment. KaLeP courses are held at CERP, students and professors from partner universities travel to Nis to attend the courses. CERP is giving students the possibility to improve their academic education. In this paper CERP will be presented and its curricula will be explained.

Exploring the Reflective and Utilitarian Benefits of Product Attachment

Maclachlan, Mary; Harrison, David; Wood, Bruce • 2009

abstract: With heightened environmental concern and the recent global economic crisis a new challenge has emerged for design; to take a more responsible role and tackle sustainability more innovatively. Not only do designers of the future need to be aware of common sustainable design thinking they should also be aware of more innovative approaches, such as, how to emotionally connect with the consumer and design products that consumers want to take care of, cherish, and repair instead of replace. This paper describes a workshop, which was developed to introduce undergraduate product design students to the area of emotional design and sustainability with particular emphasis on product attachment. The concept of product attachment was introduced by encouraging the students to become more aware of their emotions by discussing how they felt about three personal products: Favourite childhood product, favourite product that they currently own and the product they most desire to own. These products and the benefits that they offered were then discussed in order to identify how design can encourage product attachment.

Teaching Ethics in Design: A Review of Current Practice

Lofthouse, Vicky; Lilley, Debra • 2009

abstract: This paper reflects on the findings from a benchmarking study which investigated current approaches for teaching ethics to designers and engineers. The research has been carried out as part of a one year Academic Practice Award which is being delivered by staff in the Department of XXX at XXXX University (June 2008 - June 2009) and aims to develop new teaching material for teaching ethics via blended learning. Although the teaching of ethics is recognized as being important in design and engineering, the practice of doing so has only become established in the last five years and only by a limited number of institutions. This paper presents the types of issues that are currently being taught to students on a range of different types of design courses in the US and Europe. It also draws on the literature to reflect on additional methods which might be appropriate for teaching ethics in design. The lessons learned will be fed into the development of new material for integrating ethics into the teaching of design and technology students.

PIEp EDU: Education for Product Innovation

Grimheden, Martin • 2009

abstract: This paper presents results from the first two years of a large attempt at changing Swedish higher education - a system change toward synthesis, creativity, product innovation and entrepreneurship. The Product Innovation Engineering program is a ten-year governmentally funded research- and development program with an educational change program - PIEp Education. Activities are organized for three focus groups: students, doctoral students and teachers of higher education in Sweden. Activities for students include an annual thesis competition, summer schools, thesis projects and international mobility programs. A research school gathers around 25 PhD students and offers a national complement to existing university research education programs. A teachers' network gathers around 50 university teachers in Sweden to workshops in creativity, course development and exchange of experiences. Among the results presented in this paper are examples of new courses, programs and local activities showing how the Product Innovation Engineering-thinking have been embraced among the members of PIEp and are beginning to show results in terms of new products, companies and businesses.

Formation and Certification of Integrated Design Engineering Skills

Riel, Andreas Erik; Tichkiewitch, Serge; Grajewski, Damian; Weiss, Zenobia; Draghici, Anca; Draghici, George; Messnarz, Richard • 2009

abstract: Integrated Product Development is increasingly a challenge of understanding and predicting the complete product lifecycle, and of treating the product as a whole in all phases of development. This paper points out that this trend has significant implications on the competence profiles of engineers, which are nowadays insufficiently taken into account by education and training programs, as well as skill certification schemes. It proposes a skill set of Integrated Design Engineers based on the results of collaborative research and collaborations with industrialists. Key "integrated skills" include Product Lifecycle Engineering, Innovation-driven Design, Sustainable Design, Responsible Design, Networked Collaboration, Intercultural Skills, Requirements and Knowledge Engineering. We show how the established platform and certification rules of the ECQA can be used to leverage these assets to a worldwide unique qualification and certification platform for Integrated Design with a strong international and industrial orientation.

Case Study: Application of Team-Based Learning to a Mechanical Engineering Design Course Traditionally Taught in Lecture Format

van der Loos, Hendrik F. Machiel; Ostafichuk, Peter M. • 2009

abstract: The teaching of a third-year university course in design elements - e.g., gears, belts, bolts, bearings - has traditionally been taught in lecture format. In response to student feedback from the previous year, this course was redesigned using a team-based learning approach. Following the redesigned one-semester course in 2008, results include increased in-class discussion, peer-learning and attendance, as well as improved course effectiveness based on student evaluations. In addition, delivering design knowledge that is applicable to other core third-year courses and arranging for a better mesh with other curriculum components have improved design instruction in the department overall.

Analysis of CAX-Interdependencies for An EfficientBusiness-Oriented Training

Troll, Alexander; Zapf, Jochen; Rieg, Frank • 2009

abstract: Modern engineering in combination with an effective business can only be managed when there is an efficient way to handle modern tools supporting the product development process. With extended use of Computer Aided Engineering (CAE) there is a demand, not only to exchange mere engineering data but also for reasonable linking of the single tools needed. The vast amount of commercial and customized programs and their mostly uncharted interactions can delay the time to market. This necessitates special employee training as a key issue. With training on the job being too late to internalize the basic principles of CAx-education as well as project management issues, the academic teaching concepts have to be analyzed and revised to meet the requirements of today's design processes.
