Design flaws often become apparent at a time when the product is already in use and its development process, which in many cases includes extensive testing of parts, components and prototypes, is considered complete. Such flaws may reach from poor ergonomics to the total failure of the product. Often, especially when user safety is at risk, design flaws are so severe that companies are forced to announce a product callback. Petroski suggests that many (if not most) products, which we are familiar with today, have a long history of previously flawed designs [3]. This implies that designers did indeed learn from design flaws in both senses of the word “learn”: discovering the flaw and utilizing the knowledge gained about it to find a solution. As far as discovering a design flaw is concerned, it can be assumed that the feedback from those who interact with the physical products in practice – the individuals who maintain, repair, recycle but essentially use the products – plays an important role. In their previous work, the authors pointed out hat this feedback information could not only be vital for identifying potential product hazards but helps designers to review the effects of their design measures and therefore to improve their products from generation to generation [4]. In order to obtain a better understanding of how designers learn from design flaws, a mail survey was conducted that aimed at investigating company-, process- and product-related factors of this phenomenon and to answer (among others) the following research questions: • To what extent are design flaws of a company’s (or a competitor’s) product a driving force in the development of new products? • How do the designers of a company become aware of design flaws of their products? • How successful are companies in correcting design flaws? • How do successful and unsuccessful companies differ in terms of size, activity profile of their designers and characteristics of their products? • What are possible factors that influence the success in correcting a design fault?

In den letzen Jahrzehnten ist eine Vielzahl von Modellen zur methodischen Unterstützung des Produktentwicklungsprozesses (PEP) entstanden. Diese präskriptiven Modelle beinhalten oft den impliziten Anspruch, in jeder Branche und auf die Entwicklung jeder Art von Produkten anwendbar zu sein. Um dem gerecht zu werden, beschreiben die Modelle den PEP auf einem relativ abstrakten Niveau. Eine Anpassung an den Kontext der Produktentwicklung erfolgt in der Regel nicht. Existierende Ansätze ermöglichen eine Analyse des Kontexts aus verschiedenen Blickwinkeln, bieten jedoch keine konkreten Vorschläge, wie diese Analyse in den Prozess der Produktentwicklung einfließen kann. Welche Auswirkungen ausgewählte Kontextfaktoren auf tatsächliche PEP haben, geht aus einer schriftlichen Befragung von 1000 deutschen Unternehmen des produzierenden Gewerbes hervor. Es werden die Grundlagen einer Vorgehensweise beschrieben, welche basierend auf dem Kontext der Produktentwicklung die Gestaltung effektiver, effizienter, transparenter und methodisch unterstützter Produktentwicklungsprozesse ermöglichen soll.

Research was undertaken to understand how to provide the most appropriate support for novice designers in engineering design. However, how designers apply their experience and knowledge is not understood and further research in this area is required. This paper describes an observational study to understand how novice and experienced designers approach design tasks. [less ▲]

This chapter contains in its first part the core future issues I derived from the presentations and discussion sessions at the conference on "Human Behvaiour and Design : Individuals, Teams, Tools" as well as personal reflections. The second part presents my personal views on the most urgent issues in the area of human behaviour in design, and ways to proceed. [less ▲]

In this paper a comparison is made between the design processes of an individually working designer and of a group of designers based on protocol analysis. The analysis focused on the differences and similarities in the ingredients of the two processes. The basic ingredients used for the analysis were: Issues, Arguments, Alternatives, Criteria, Decisions, External information, and Others. Comparisons have been made between: the group as a whole and the individual designer; the individual group members; the individual group members and the individual designer. The results provide a first step towards a better understanding of the differences between group and individual work. The paper also discusses some of the limitations of this type of study. [less ▲]

An increasing interest in the application of artificial intelligence tools and techniques can be observed in several fields, including engineering design. Due to their natures, engineering design and artificial intelligence, more than "conventional" programming paradigms, seem to be made for each other or at least seem to promise an important leap forwards in the development of computer tools for complex tasks. However, the same natures demand more research to be done not only in the field of artificial intelligence, but also in the field of engineering design. For a genuine integration of Artificial Intelligence with Engineering Design both research areas should go hand in hand. After a short history of the relation between artificial intelligence and engineering design and some of the typical characteristics of engineering design, an overview is given of the different aspects of the design process supported already by artificial intelligence. Finally research areas are described that emerge if the areas supported are projected in the design space. The point of view taken is engineering design with an emphasis on mechanical engineering design. [less ▲]
