Core Part

This paper firstly discussed the definition of knowledge integration in the field of product development and proposed the multidimensional knowledge integration model which could be the guidance during the implementation of knowledge integration. Subsequently the framework of knowledge integration is presented, three layer (the enterprise distributes resources layer, enterprise managed knowledge layer and product development process layer) in the framework are explanted respectively. The ontology is introduced to provide the semantic fundament for the framework. The structure of integrative ontology is studied and constructed with OWL(Ontology Web Language). The ontology plays an important role in knowledge organization and knowledge service and it’s the core part of the whole framework. At last a prototype system based on the previous techniques is developed and basically fulfills knowledge integration in product development process.

Abstract The importance of conceptual modelling more and more becomes recognized in the industrial practice, since it is commonly known that it is during that phase of the product development process where fundamental choices are made that have a strong influence on the result of the development — the process! The process of product development can only be efficient if it is basically put into practice methodically. The time additionally invested in the first steps of the methodical process of product development as it is described in the German guideline VDI 2221 prevents from forgetting important specifications or even overseeing possible ways of solution. This way the phase of conceptual modelling can result in a saving of time needed for product development due to fewer iteration loops for the correction of mistakes in later phases of the process and an increase of the product quality, too. The prerequisite of the efficiency of conceptual modelling is a definition of the product specifications which is as precise as necessary and as abstract as possible in order not to restrict the amount of solutions in an unnecessary way. Looking at the functions a product to be developed has to fulfill, the requirements list serves as a basis for the definition of function structures in which all functions and the relationships amongst each other are defined. This function structure can be utilized not only for the description of the product in an abstract way, but also for structuring the development process as well. With the definition of interfaces between parts of the product, implicitly interface specifications for the work on different parts of the product are defined. The function structure, therefore, can be used as a tool for management in the product development process. Because of this, the information summarised in these documents must be available throughout the entire development process the information technological support of these tools should be standard. Nevertheless, common CAD-Software does not support any step of conceptual modelling. In this paper an information technological support for conceptual modelling is also presented. Furthermore, it is shown what kind of changes in and extensions of common CAX-Systems would be necessary for the realisation of this theory.

Abstract Breaking into the consumer market, Virtual Reality (VR) has now penetrated wide areas of the industrial market. Rapidly developing technologies are opening up new application possibilities with low cost and high quality solutions. Although VR has been used exclusively as a marketing tool in companies up to now, it is still being extended to support all areas of the complete product development process. However, this is also accompanied by the difficulty to manage the amount of functionalities and design options associated with VR. Developers of such VR systems must nevertheless maintain an overview of the multitude of technological and content-related possibilities and bring them in line with the requirements of VR customers or VR users. At the same time, VR customers must also have an idea of the technological possibilities and formulate their vision of a VR system as precisely, completely and goal-oriented as possible. In the end, both sides must find a common level of communication in order to record the characteristics of the VR system in the form of a requirement specification or an offer. Factors such as different terminologies and different views about the product development process along with the diverse knowledge about VR functionalities on both sides complicate this process. This article is intended to show the concept for a toolbox that supports the definition of a customer-specific VR solution. This shall exploit the full potential of VR for the customer’s specific product development process in VR. The generic product development process will be studied and the VR application areas will be located. In this regard, a classification of the main components of VR systems is performed. The goal of such a classification is to establish a relationship between the product model (along with product specific properties and relationships) and the VR system components. As the field of VR does not yet have an established set of standardized terms, a definition of all terms in this context can help to improve communication between customer and developer. This article shows how a toolbox for agencies and development departments must be structured so that the VR developer can design, evaluate, calculate and develop a complex VR system in a customer-oriented way. Furthermore, the vision of the toolbox presented in this paper also has the goal that the VR customer can specifically formulate his/her requirements in a customer-specific way that leads to an easier understanding for VR developer and eventually to a VR solution. Finally, the possibility of extension of the presented toolbox structure is discussed to automatically generate specification proposals and suitable technology recommendation based on the problem at hand.

This case describes the redesign of a mobile eReader application. The purpose of the redesign was to convert an existing eReader from a means of only reading books into a tool for informal learning. The case reports how the design team’s definition of informal learning evolved throughout the product development process, and how design deci-sions were influenced by this changing definition. Over the period of time covered in the case, the eReader evolved from a tool used for reading eBooks, into one meant for personal study, and then into a product that supported serendipitous discovery of inspiring material (built under a philosophy that informal learning meant that people were able to discover interesting and uplifting material without exerting effort to find it). The end point of the eReader’s evolution was as a subscription service for the company’s eBooks and digital audiobooks, to allow customers to continually use them for educational purposes. This case is structured around the four iterations of the eReader design process. Each iteration reports how design decisions were made and what kind of results were achieved.

Abstract Starting with the motivation to provide manufacturing feedback to designers and to reduce bottlenecks in the design-manufacturing transition, algorithms for constructing molds and dies are presented. The concept of “virtual manufacturing” serves as the umbrella for this work. Computational prototypes, rather than hardware prototypes, can greatly speed product development, process design, and process tooling development. The work presented here contributes directly to all three areas, since automated tool construction enables accurate, detailed Design-for-Manufacturing feedback to aid product development, enables process design through simulation, and provides an initial tool design that can be enhanced by a tool fabricator. A series of algorithms are presented for the automated construction of tools from a purely geometric reasoning viewpoint. Starting with a solid model of a component, undercuts are found and classified, then moving tool sections are constructed. For external undercuts, accessibility directions are found and are used to construct tooling side actions. Automated undercut accessibility determination has not been previously previously reported in the literature. For internal undercuts, form pins are constructed that access the undercut through the core of the tool. Undercut classification is important since their cost implications can be reported back to the component designer during design. Two examples illustrate the application of the algorithms.

An accurate understanding of users' needs is essential for the development of innovative products. This article presents an exploratory method of user centered research in the context of the design process of technological products, conceived from the demands of a large information technology company. The method is oriented - but not restricted - to the initial stages of the product development process, and uses low-resolution prototypes and simulations of interactions, allowing users to imagine themselves in a future context through fictitious environments and scenarios in the ambit of ideation. The method is effective in identifying the requirements of the experience related to the product’s usage and allows rapid iteration on existing assumptions and greater exploration of design concepts that emerge throughout the investigation.
