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.

Product Concepts

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.

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.

Summary A submersible is defined as a neutrally buoyant submarine which relies largely on the buoyancy of the hull rather than gas or liquid filled floats at ambient water pressure. 29 different kinds of submersible have been built in USA and 15 in other countries. One has been built in England. Half of these do not go below 2000 ft and one third do not go below 1000 ft. The minimum safe weight for a vehicle is 5 tons at 1000 ft and 10 tons at 20 000 ft. A useful research or light work vehicle must be twice the minimum weight, and a heavy work vehicle in the 30-100 ton range. High utilisation factor can only be obtained with special handling and support equipment, underwater navigation aids, high manoeuvrability, and a reserve of speed, life support, payload, and endurance. Principle applications of submersibles are in scientific research, geological mapping, prospecting, the oil industry, dredging, pipe-laying, and search and salvage.

Purpose – This paper aims to develop a methodological approach to place product analysis that aims to identify the distinctive ideas of places. Design/methodology/approach – The methodology included two stages: first, classifiers of place product uses and technologies were constructed on the basis of the product concept abstraction (Study 1) and then they were used as tools to systematize data about the attributes of city districts and the everyday activities of their residents to further identify product concepts (Study 2). Findings – Product concepts of five Moscow districts were formulated as sets of benefits or district uses (needs satisfied and activities encouraged) offered to residents. The concepts are expressed in terms of typical constructions but reflect the distinctive features and specificities of the districts. Research limitations/implications – Defining places as product concepts pushes the place product analysis, benefit and lifestyle segmentation forward. Additional place product dimensions and investigated places are advised to improve the reliability of the used classifiers as a tool for documentary research. Practical implications – The developed analytical procedure is a much-needed supplement to existing techniques used to shape the product strategies of places. Identifying contradictory uses helps make product decisions that are appropriate in concurrently supporting all these uses, including providing spatial differentiation of the place product. The study results are thus useful for the development of city master plans characterized by long planning horizons and a high degree of conceptualization. Originality/value – The paper proposes a new method for place product analysis that combines the advantages of both standardized and narrative approaches, introducing a convenient way to address the issue of clarity when transforming a variety of place attributes into core place values and eventual place brands.

Customer evaluation of concepts plays an important role in the design of handheld devices, such as bottles of douche gels and shampoos, where the phenomenon of grasping needs to be evaluated. In these applications important information on the aspects of ergonomics and user behaviors could be gathered from computer simulation. It is our ultimate goal to develop an environment in which users and designers can freely interact with product concepts. In our approach to grasping simulation there is no tactile feedback and we do not measure the exerted grasping forces. There is no wiring of the human hand, and the users are not limited in their movements. We measure the motion of the human hand, compute the grasping forces based on anthropometric data, and simulate the reaction of product concepts in a physically based virtual reality environment. Our contribution consists of: (i) a method, which takes into account the anatomy of the human hand in order to determine the maximum grasping forces, and (ii) an approach which enables to control the grasping forces based on (a) the penetration of the virtual human hand into the virtual model of product concept (b) the posture of the grasping, and (c) the angles of the joints. The paper reports on the framework of our approach and presents an application.

Two field experiments were conducted to explore the effects of varying levels of product warranty, manufacturer reputation, and price on consumers’ risk perceptions and affective responses to new product concepts. Data were collected from a consumer panel in a new product concept test format for a tire product and for a computerized exercise device. Results from structural equation analyses reveal the important role of warranties and other extrinsic cues in reducing consumers’ risk perceptions and enhancing their affective responses to innovative product concepts.

New product concept development is considered to be a critical step and the main determinant for the success or failure of new product development. This paper introduces a new methodology for the evaluation and selection of new product concepts using Data Envelopment Analysis (DEA) and Conjoint Analysis (CA). The proposed methodology integrates customer perceived value of the new product concepts through the use of CA and uses this perceived value as a measure for the new concepts performance. In addition, the methodology takes into account the development burden that a company has to perform to bring the new concept into a state of market readiness. This development burden is estimated by determining two main factors, namely the burden to produce and the burden to sell the new product concept. The customer perceived value and the development burden are both used in DEA to evaluate the new product concepts resulting in the selection of the best product concept. The applicability of the proposed methodology is illustrated through a case study. Keywords: Product development, concept selection, data envelopment analysis, conjoint analysis.
