Concept design is the most critical step in product development. To a large extent, its quality determines the fate of the product. Support for concept generation is mainly intuitive beside few recent attempts to develop concept generation support methods. In this paper, we review and exemplify the importance of quality product concepts and the available literature on concept generation. We present a framework that is simple yet comprehensive for generating optimal concepts in diverse disciplines. The framework rests on a method for optimal concept generation that has sound mathematical foundation. The method has been evolved and refined over years of practical experience and research. The present version has been used in numerous successful real projects. We illustrate the use of the framework in two case studies and explain the sources of its generality. The framework is flexible thus can accommodate diverse design concerns as well as model concept design in the context of new business practices such as outsourcing.

Product concept generation and concept design are major activities for obtaining an optimal concept in new product development (NPD). A customer requirements driving new product concept generation method is addressed in this paper. This study proposes a new method to generate product concept, through which NPD team acquire customers’ requirement and product attributes. The new method is based on integrating of Naïve Bayes cluster and rough set theory (RST). It takes marketing strategy, business strategy into consideration, which makes new product development more effective compared with the traditional method. We believe that the proposed method will have a positive significance on the future new product development

Product Concepts

The task of designing product forms is becoming increasingly challenging as consumers demand visually pleasing products that meet functional requirements. Researchers have been working on product concept generation systems that support designers in exploring design spaces to produce large numbers of product concepts from which possible solutions can be selected and developed. Such systems typically utilize the searching capabilities of metaheuristic techniques to explore solution spaces and generate variations of product forms. Recent research work in this domain has focused on hybrid approaches that combine metaheuristic techniques with other methods such as shape description and neural network approaches. This paper provides a review of the application, effectiveness and prospects for these approaches.

AbstractProduct concept generation and evaluation are critical for the success of new product developments (NPD) because managers need to select the most profitable product concepts. However, current approaches can be restricted to single products and do not cover product families' effects. Similarly, they do not necessarily capture all requirements and usually lack extensive cost analyses. Thus, this paper proposes a framework supporting product concept generation and evaluation by providing an accessible conceptualization to overcome the limitations. Using the so-called Extended Axiomatic Design (EAD) supports designers and managers to configure the requirements across product concepts' various domains while concurrently evaluating their economic consequences. The study applies the framework on a simplified case of a bottle manufacturer to conceptualize four product concepts. The case illustrates how the EAD can be used as a virtual testbed to generate and evaluate new product concepts. Finally, designers and managers can make more informed decisions about product concepts by considering their economic and engineering selection criteria to select the most profitable NPD project configuration.

Selection Of

Only a small proportion of examination candidates have practical experience of reversions and life interests, and the purpose of this paper is to indicate some of the practical points which arise in transacting this class of business; the selection of appropriate bases for mortality, interest, valuation of funds and Estate Duties do not fall within the scope of this paper. Reference to strictly legal aspects are no more than incidental.Since 1945 there has been, on the basis of new business figures, a marked revival in reversionary business defined as covering purchased reversions and life interests, and loans secured thereon. On balance-sheet values the reversionary business of British life offices in force at 31 December 1948 was rather more than £15m. There was approximately the same volume at 31 December 1943, but at 31 December 1938 there was about £2m. more in force. Over the 10-year period loans have decreased by about £3½m. to only little more than £5m., but purchases have increased by about £1½m. to more than £10m. These figures can give no more than an approximate picture of market value through the different methods of arriving at balance-sheet values, but they serve to show that reversions and life interests continue to form an important part of the assets of certain British life offices.

Effective Carrier

The mechanical product concept design method based on reverse engineering (RE) is a new approach in the concept design domain. The functional pattern is thought as an effective carrier and medium of mapping function to structure, which provides an efficient path for expressing the intrinsic evolution rule of the complex mechanical qualitative structure. And it is used as the information organization unit and the assembly product information model, which could give some help to express the design knowledge effectively. Therefore, we proposed a mechanical product concept design method based on RE. The examples indicated that this method is feasible and it provides a practical technical way for the knowledge reuse and continue innovation of the existence products.

Abstract Rapid shape creation and visualization of solid models remains a tedious task despite advances in the field of Computer Aided Design (CAD)/Solid Modeling. CAD systems require a significant level of detail, such as vertices, edges, and faces to be specified by the user, even before the simplest of shapes can be created and viewed. In addition, most CAD systems have an essentially 2D interface for designing artifacts. This makes artifact visualization, for example by interactive rotation, difficult since all manipulations have be achieved by 2D translation of the mouse or by typing in the required angles of rotation. The limited visualization capability and the requirement to create shapes through the specification of low level entities is especially cumbersome in the concept shape design stage. This paper describes the Conceptual Virtual Design System, COVIRDS, a tool for product concept design. COVIRDS provides an intuitive voice and hand input-based interface for modeling of products using a ‘construction’ approach. Product shape models are created by ‘attaching’ simpler parametrically defined ‘Shape Elements’ to other elements to create more complex models. Voice commands are used to instantiate shape elements and change their parameters, for example, the width, length and height of a block element. 3D hand input is used for positioning shape elements during element attachment. The voice and hand input-based interface together with a stereoscopic visual display facilitates rapid creation and visualization of concept shape models.

Double Digit

In the past three decades, Chinese economy has been arresting the worldwide attention for its double-digit growth rate. Playing a leading part in general economic development, Chinese manufacturing has been contributing a substantial portion in the total GDP growth. However, a national key project, the Research of China National Manufacturing Strategy, has found in the last several years that Chinese manufacturing has already lost its competitiveness due to the void of cheap labor force (New Labor Law in China), the rising costs of raw materials and energies, and the more rigid requirements for environmental protection. Chinese manufacturing has met its Waterloo and calls for an urgent business transformation if it wants to survive and sustain its development. Based on fundamental research, authors of this paper propose a new business conceptual model, SERVICE-MANUFACTURING, which focuses on the seamless marriage of service and manufacturing and how this new model can be implemented in real business practices.
