User-centered product design (UCPD) and especially its methods and tools offer a lot of benefits to product development. By using specific data of the user group or by including them into the design process, systems with better functionality and usability arise. However, including the users in an optimum manner means to include them over the whole product development process, which is costly and often too time-consuming regarding the ever shorter product life cycles. An extensive application of UCPD methods is therefore usually not practical for industry. In order to (1) support the user-centered development process in general and (2) support the selection of appropriate UCPD methods, a multi-channel human-system interaction framework is proposed. It is derived from existing human-computer and human-machine interaction models and further includes additional factors influencing the human-system interaction. However, the framework itself needs further and more detailed elaboration and discussion and currently lacks an allocation of UCPD methods.

Abstract In socialistic countries, customer satisfaction and the market conditions were not of high priority: Some selected parts of the market products were of satisfactory costs and quality to customers. Quality and costs of a product decide on its success in the world-wide market. The wishes and expectations of the customer for a high-quality and low-priced product continue to grow, however, with the desire for faster availability of this product. The customer determines also the delivery time and other competitive factors as the durability of the product. At present the trend goes towards shorter product life cycles, which in turn requires reduced time spent on the product development. With these complex market requirements and growing diversity of the products the engineer faces new challenges in his development tasks. It can be paraphrased as follows: In reduced lifecycles a quality-assured and advantageous product has to be developed despite increasing complexity of the design and demands for reduction of material used, manpower and monetary spending. For the solution of this complex problem the following suggestions are tested and implemented: • Structured design process for the development process, • Simultaneous work where ever possible during the development stages, • Employment of modern resources for the product development, • Use of information technology and • Implementation of rapid prototyping for models and in secondary manufacturing processes. An important research field at the Department of Mechanical Engineering Design at the Otto-von-Guericke-University Magdeburg is research and further development of productive procedures and tools for the realization of a computer integrated product development process. This process includes the effective application of technologies to produce the prototypes for presentation, producibility analysis and production. Of particular interest is the closed process chain (loop) from Solid Modeling via Rapid Prototyping and 3D-Digitizing where the entry point of this process chain depends on the needs of the application or particular interest of the innovating company. Information for faster and more competitive preparation, verification and Re-Engineering of existing and established products, which have to be adjusted to the world-market needs, will be made available. The results of this applied research offer opportunities to display new developed products for the lagging industries in the former East Germany, and furthermore arranging for necessary venture capital to produce the product, to gain information about possible suppliers and manufacturing opportunities in order to minimize the investors’ risks of an enterprise.

Abstract Idea visualization is a critical tool in a product development process. From early idea sketches to 3D prototyping, designers often visualize ideas for themselves and others in the process of feedback and refinement. The viewers of these ideas (clients, investors, collaborators, and consumers) rely on these visual presentations to evaluate the potential of a designer’s idea. Although sketching ideas is common practice in the product design industry, little is known about the extent to which presentation quality influences viewers’ evaluations of ideas. This paper examines the power of product sketch quality on perceived idea evaluation. In the present study, a total of 400 participants were asked to evaluate a set of product ideas presented with and without a sketch. The results show that when product sketches were presented, the participants were heavily influenced by the sketch quality when evaluating the value of the idea, and the concept ratings were somewhat different when sketches were not present. The results imply that viewers’ perceptions of idea worthiness are possibly dependent on how an idea is visually presented.

Abstract This paper describes a decision support tool that can help a product development team reduce manufacturing cycle time during product design. This design for production (DFP) tool determines how manufacturing a new product design affects the performance of the manufacturing system by analyzing the capacity requirements and estimating the manufacturing cycle times. Performing these tasks early in the product development process can reduce product development time. The paper presents a comprehensive DFP approach and describes the components of the DFP tool, which gives feedback that can be used to eliminate manufacturing cycle time problems. We present an example that illustrates the tool’s functionality.

Prior to the acceptance of computer aided engineering (CAE) software in the product development process (PDP), product development was characterized by a design-test-redesign-test cycle. This activity was time consuming and resource intensive. As CAE software tools have been integrated into the PDP, the PDP has been characterized by a design-simulate-redesign-test cycle. The addition of CAE tools to the PDP has reduced the time to market and resource consumption. Although the benefits of the integration of CAE software in the PDP process have been realized, there still exists an arbitrary relationship between the results from the CAE tools to engineering decisions regarding product design.

Abstract Conventional product development process employs a design-build-break philosophy. The sequentially executed product development process often results in a prolonged lead-time and an elevated product cost. The proposed concurrent design and manufacturing (CDM) process employs physics-based computational methods together with computer graphics technique for product design. This proposed approach employs Virtual Prototyping (VP) technology to support a cross-functional team analyzing product performance, reliability, and manufacturing cost early in the product development stage; and conducting quantitative trade-off for design decision making. Physical prototypes of the product design are then produced using Rapid Prototyping (RP) technique primarily for design verification purposes. The proposed CDM approach holds potential for shortening the overall product development cycle, improving product quality, and reducing product cost. A software tool environment that supports CDM for mechanical systems is being built at the Concurrent Design and Manufacturing Research Laboratory (http://cdm.ou.edu) at the University of Oklahoma. A snap shot of the environment is illustrated using a two-stroke engine example. This paper presents three unique concepts and methods for product development: (i) bringing product performance, quality, and manufacturing cost together in early design stage for design considerations, (ii) supporting design decision-making through a quantitative approach, and (iii) incorporating rapid prototyping for design verification through physical prototypes.

A major challenge in industry today is to reduce the cost and cycle time in product development while maintaining enough flexibility to adapt to changing markets. Businesses are requiring more and more flexibility in order to produce custom goods at low cost. A new strategy called the Product Design Generator is presented to provide flexible product platforms through an automated design process where product variation is built into the product development process and is achieved through scalable and in some instances modular parametric models for a given product platform embodiment. A case study of web-based Product Design Generator is presented. The axial turbine disk Product Design Generator demonstrated cycle time reduction from 500 man hours to 15 minutes. This new product development strategy has demonstrated the potential to provide engineers the ability to study more potential design solutions, reduce the number of opportunities to introduce error in the product development process, and allows companies to apply a consistent design process across the organization.

Current trends in product development process highlight the increasing adoption of digital data and virtual processes. Nowadays, a huge amount of product data are collected without a clear management strategy and, oftentimes, they dont even cover the whole product development process. A global and integrated planning about information needed to sustain product design process is not a trivial task and, usually, companies underrates this issue. From the perspective of virtualization of processes, and then their automation, the lack of structured knowledge is certainly awful. This paper aims at making a critical analysis how product data evolve throughout the product design or configuration process and how they impact the product development activities. Efficient digital product twin allows companies to virtualize processes and leverage their automation, but it is important to understand how the knowledge management should be carried out. Three case studies, directly experienced by the authors, have been investigated analyzing digital data and virtual tools that allow companies to automate the design process, each one bringing a peculiar perspective of the problem.

Product development process modeling (PDPM) is one of the key techniques for product development (PD). The main aim of PDPM is to provide a product design chain (PDC) for PD. To increase the efficiency of PDPM, a project-driven e-design system is proposed in this paper. There are two modules in the system: task decomposition and product design chain construction. Additionally, key techniques for enabling the system are discussed. Finally, an example of steering oil pump design project is studied to demonstrate the system.
