- Web-based activities are becoming more and more common. Telephoning free of charge over the Internet (IP - Internet Protocol) has become much used within a short period of time. In a similar way videoconferences can be held in an inexpensive way over the Internet. Equally, radio and TV broadcasting over Internet will become more and more common. It should be possible to use inexpensive web-based support both during the creation of a new product concept and during the following product development. However, two types of dilemma exist: the mental problem and technological problems. In tests in late 2004 and early 2005 we have found that mentally related problems seem to be the most difficult ones to overcome as most people found it of outmost importance to meet in person to be creative. We have also experienced that the technology still is not good enough for combined IP-based meetings. However, the latter is a technology problem that seems easier to be solved. We have experienced that using web-based support can be beneficial in many ways. We believe that in the future the web will be used even in the creative process to bring forward product concepts. As it offers global cooperation without expensive and time consuming travelling, it is of great interest to innovative enterprises.

- In a fiercely competitive business climate, which is increasingly characterized by global alliances, partnerships and outsourcing agreements, companies struggle to decrease the negative impact of geographic distance on development efforts. The role of workspaces for collaborative design is gaining considerable attention, and there is currently an increasing interest in moving from individual tools or technologies to a more inclusive view of collaborative workspaces. This paper reports on the underlying motivation and justification for a new collaborative design studio at Luleå University of Technology, Sweden. The studio provides a rapid-response environment, in which the significance of issues raised through ethnographic observations of engineering work can be evaluated and solutions offered.

A situated question-driven and model-based approach to design reasoning

Konferensbidrag (refereegranskat)abstract
- A complex system is a system with many components and interconnections, interactions, or interdependencies that are difficult to describe, understand, predict, manage, design, or change. Complex technical systems are characterized by the level of complexity and uncertainty. Uncertainty appears mainly in system behaviors and the ways different aspects of a system change with time. The uncertainty, which can be seen as a direct consequence of the complexity and it increases with the scale and the scope of the system, will normally decrease as we gain insight and knowledge about the system. Engineering design of complex technical systems depends much more heavily on computer simulation than design of smaller and less complex products. The main objectives for simulations is to assist design reasoning by helping to identify unintended and accidental interactions between components and to assess and verify the system in early design stages. The special character of product development and engineering design require that this reasoning process is situated and that the model definitions are based on "systems thinking". This paper elaborates on a formal basis for model-based design reasoning and presents a formal knowledge framework for model-based design reasoning.

The concept of functional surfaces as carriers of interactive properties

Konferensbidrag (refereegranskat)abstract
- The perceived use and attractiveness of a product relies on its subjective understanding by one or several human being(s) to a great extent. The attractiveness of a product depends strongly on its aesthetic appearance and how we perceive the whole product and its external aesthetic and ergonomic features with all our senses in relation to the performance we, for some reason, expect from the product. Fulfillment of the technical functional requirements and the cost constraints is often seen as an obvious prerequisite for an attractive product but it is not seen as the differentiator among competing product. It is increasingly important that the product also have distinctive interactive properties of a semiotic, ergonomic and/or aesthetic nature that distinguish the product from other products on the market. Consequently, development of many types of products benefits from an integrated and holistic treatment of both the technical and the interactive product aspects. The fact that products are designed by someone to be perceived by someone else makes treatment of ergonomic and aesthetic requirements and implementations quite complicated and even fuzzy. A significant challenge to design research is to find ways to represent the "hard" technical requirements and the more "soft" interactive requirements, the implementations of the technical and the interactive properties, and the relations between these types of requirements and properties. This paper presents a model-based approach that addresses this challenge. Interactive and technical functional surfaces and how they fit into a general modeling principle of technical systems are elaborated on. The general modeling principle includes both technical and interactive interface models. This paper, furthermore, presents an integrated matrix-based representation of the technical and interactive properties of a technical product and relates these properties to the stated customer requirements. The presented approach is exemplified with a recent design project.
