  • Scalable product platform design based-on design structure matrix and axiomatic design   Order a copy of this article
    by Xianfu Cheng, Guangying Lan, Qihang Zhu 
    Abstract: Product platform design has been recognized as an effective means to establish and preserve competitive status in the market and to maintain the economies of scale and scope, while keeping production costs to a minimum. To this end, a new design method for scalable product platform is presented based on design structure matrix and axiomatic design. Initially in this process, the customer needs are analyzed, and then the common and individual needs are identified. Second, the key functional requirement parameters are extracted and mapped. Next, a design matrix is established. The functional structure decomposition figure and the design matrix are combined for constructing a design structure matrix. Then, an extension clustering algorithm is utilized to cluster the elements, and then common variants and adjustable variants of product platform are recognized reasonable. Afterwards, a product platform design scheme based on a design structure matrix and axiomatic design is determined. Finally, a product platform on electro-hydraulic drum brakes is developed. The results demonstrate the effectiveness and practical value of the new design method.

  • An approach to integrate numerical simulation within KBE applications   Order a copy of this article
    by Giorgio Colombo, Caterina Rizzi, Daniele Regazzoni, Roberto Morotti 
    Abstract: This paper presents an approach to automate and integrate numerical simulations within Knowledge-Based Engineering applications to improve the use of simulation tools, especially in SMEs. Main discussed issues concern: i) the importance of the CAD model as an input of the process; ii) data migration from CAD to CAE tools; iii) model characterization; iv) effects of parameters variations; v) simulation steps; and, vi) results evaluation. In addition, formalization and representation of rules and procedures to automate the design process, in particular the simulation tasks, are presented. Two case studies are described to explain and verify the approach. The first case concerns the design process of centrifugal industrial fans, during which simulation tools are used to verify the correct sizing of impeller blades. The second one is related to a non-industrial process; actually, it regards a medical device, and more precisely lower limb prosthesis. Finally, main results are discussed.

    Abstract: An ontology is definedas a structured, hierarchical way for describing domain knowledge. Research work regarding ontological engineering has yielded fruitful results, but these methods share a common drawbackthey require significant manual work to generate an ontology,which limits the usefulness of these approachesin practice. In this paper, we propose a computational model that combines data-mining, natural language processing (NLP), WordNet, and a novel class-based n-gram model for automatic ontology discovery and recognition from existing patent documents. A pre-built ontology library was constructed by gathering knowledge from engineering textbooks and dictionaries.Then a dataset of engineering patent claims was split into training (80%) and validation (20%)subsets. The pre-built library and WordNet were used to generate class labels for constructing class-based n-gram models in a training process.The holdout validation dataset validated the accuracy of the proposed method. The results showed that the average accuracy was 87.26% for all validation samples. The best performance was 89.26% for hybrid vehicle patents, and the worst performance was 85.15% for patents related tocomposite image projectors.

  • Supporting Decisional Processes in Design: a case study in the Space Industry   Order a copy of this article
    by Francesca Montagna 
    Abstract: The approach proposed in the paper considers a decision perspective on New Product Development (NPD) together with the integration of different domains and tools to support design activities. In particular, it highlights the need for methods and tools that investigate and support the design decision context, improve communication and reduce uncertainty in engineering design situations. The proposed approach has been implemented in a French-Italian space industry company.

  • IT-enabled Product Innovation: Customer Motivation for Participating in Virtual Idea Communities   Order a copy of this article
    by Ulrich Bretschneider, Jan Marco Leimeister, Lars Mathiassen 
    Abstract: Virtual idea communities (VICs) such as Dells Ideastorm are very popular in practice. In VICs, customers of firms can submit ideas and collaborate to support product innovation. This customer-based ideation is not new per se. Small groups of customers have been brought together in lead user workshops or focus groups since the 80s to support product innovation. However, bringing customers together in VICs represents a new form of IT-mediated ideation with customers. While extant research has provided insights into customers motives for participating in traditional ideation, we know little about the motivations that drive customer participation in this new form of IT-enabled ideation. Based on a survey of customer motivations for participation, we found evidence for motives that arise directly due to the VICs IT-ability to support visualization of customer ideas, to give feedback on ideas, and to support customers social interactions. As a result, VICs are perceived as a way to demonstrate personal capabilities, for getting recognition, and for facilitating social interaction. We discuss these findings in relation to extant research on customer-based ideation.

  • Investigating a totally digital approach to concept generation during industrial design practice   Order a copy of this article
    by Mark Evans, David Cheshire, Eujin Pei, Ian Graham 
    Abstract: During the professional practice of industrial design, digital methods are used extensively to support the generation, development and specification of creative three dimensional (3D) form. Despite the increasing capabilities of digital methods, the distinctive nuances of current practice continue to require the use of non-digital methods, particularly during the highly creative concept generation activities. This paper reports on a research project that combined emerging and established digital design technologies to define an approach for total Digital Industrial Design (DID) that employed only digital methods (e.g. no pens/paper) with no post-process finishing (e.g. smoothing/painting of rapid prototype parts). To evaluate this theoretical approach, action research was employed in which all phases of DID were used to design two stylistic variations of a consumer product with data collection using a diary through the design process and coded analysis of outcomes. The paper concludes that DID has the greatest potential for change and benefit during the concept generation phase, where haptic feedback modelling and monochrome 3D printing have the capacity to replicate some of the qualities of tactile form-giving that is associated with workshop-based sketch modelling by hand. When integrated with photorealistic visualisation, low fidelity appearance models have the potential to reduce design timescales. To maximise impact, the case study was translated into in a web-based resource ( to facilitate understanding of the process and designed outcomes from DID.

  • Resonance Testing: An Industry Approach for Experiential Concept Evaluation   Order a copy of this article
    by Lassi A Liikkanen 
    Abstract: This paper describes a professional practice in user-centered product concept design that is embedded in a method called resonance testing. It is a nimble method used and developed in industry to ensure that desired properties of design are communicated to the user through the design. It tests product concepts for emotional and functional design attributes such as personal identification and meaningfulness. In resonance testing, the users of a specified segment experience design artifacts of variable abstraction levels to see how they perceive the qualities of a concept and how it matches their preferences. We find that literature lacks both effective user feedback solutions for early product decisions and discussion of the known challenges for doing that. The paper describes how resonance testing generates qualitative insights, builds confidence in new concepts, and helps designers to develop the right concept for further development. We present two cases studies of utilizing this method.

    Abstract: The notion of context seems to be a growing subject in the engineering sciences. Several studies have pointed out the necessity to address the contextual limitations in collaborative design projects. It has been identified as one of the major factors that contribute to inadequate knowledge reuse in design projects. Nevertheless, the definition of the context depends on the subject and the field of application. In this paper, we point out different definitions of the context in artificial intelligence, engineering and cognitive sciences. In this research study we present a proposition for context modelling representing only one part of collaborative decision-making support. The research study presented in this paper is a result of collaboration with one of the French car manufacturers. Within the conceptual model of collaborative decision-making, we propose to integrate the information concerning three different contexts: decision, project and enterprise context. The aim of this model is to help and support the project team in project management.

  • Success Factors of Product Concepts for Convergence Products in the Telecommunications, Internet, Media, and Entertainment Industries   Order a copy of this article
    by Daniel Holle, Stefan Huesig, Michael Dowling, Nikolaus Mohr 
    Abstract: The convergence of the Telecom, Internet, Media and Entertainment (T.I.M.E.) markets has been taking place for decades, but many convergence products designed and marketed by experienced corporations have failed. We propose that the problems associated with newly developed convergence products are often the result of poorly defined product concepts. Specific research on product development and product concepts that is focused on convergence in these industries has so far been largely lacking. In this empirical study, we derived 18 hypotheses on the success factors of convergence products based on information attained from a literature review and interviews with industry experts. We tested these hypotheses using a large scale survey conducted in Germany, Austria, and Switzerland. We identified 13 success factors as being relevant for product market success, seven of them being of particular importance. The findings expand on the existing findings on success factors for product development as well as convergence research and practice.

  • Utilising Computerised Tools and IT in New Product Development to Constitute Firms Financial Performance and the Impact of R&D Intensity   Order a copy of this article
    by Sadami Suzuki, Takao Enkawa, Tanyanuparb Anantana 
    Abstract: By using New Product Development Scorecard (NPDSC) as a data collecting tool, field surveys were conducted for 396 participating firms in 14 Japanese manufacturing industries. According to the analyses results, two elements of Development strategy and organisation and Development production technology are identified as enabling f actors for the complement of utilising tools and IT in NPD. It is also suggested that in order to make a positive impact on financial performance, tools and IT should have to be incorporated with these enabling factors. In addition, it is found that level of utilisation capability of tools and IT is significantly higher in high R&D intensity group compared to the low one. And level of R&D intensity affects the implementation methods of tools and IT for NPD and the contribution to financial performance, as well. Consequently, useful managerial implications are provided in this work.

  • Predicting the competitive advantage of design projects to dynamically support decisions in product development   Order a copy of this article
    by Yuri Borgianni, Federico Rotini 
    Abstract: Many product development initiatives are planned on the basis of the supposed capability to generate customer satisfaction. However, market and technology conditions can undergo several transformation during the execution of product innovation projects and jeopardize the basic assumptions taken at the beginning of the design cycle. Among the changing factors, the observed alternation of radical and incremental transformations of product architectures is viable to influence the success chances of new products. Such an aspect is taken into account in the decision support tool described in the paper, which can be employed to select the most beneficial alternatives in a set of different product ideas.
