Abstract

In the face of an ever-changing global market, companies able to launch new products meeting consumer needs faster than their competitors may not only gain a larger market share, but also shorten the development cycle to reduce costs. However, there are currently no universal design strategies and tools for evaluating the design of consumer products. Therefore, the purpose of this study is mainly to formulate a systematic and innovative product design strategy and evaluation tool, so that designers can use them to select the key factors when designing consumer products and design products that meet customer needs in the shortest development cycle. First of all, this study was designed to sort out general design methods and influencing factors in consumer product design based on theoretical analysis and expert interviews. Next, a questionnaire survey of 15 design-related experts and scholars was conducted, and the most important design methods and design factors were selected using the Fuzzy Delphi Method (FDM). After that, the analytical network process (ANP) method was used to obtain the priority weight of each design factor, and select the optimal product design strategy, QTPCP, and the deciding elements that affect consumer demand for products, including 2 dimensions, 11 design elements, and 38 design factors, making theoretical contributions to product design management. The design strategies and evaluation tools developed according to the conclusions are helpful in comprehensive planning and design selection for products of different natures, and make practical contributions, enabling product developers or designers to efficiently select the optimal product design when faced with different new product designs.

Highlights

Consumer products refer to products provided for end consumers to use
To meet the requirement of product design activities, we have developed a set of innovative product design strategies “QTPCP” based on the theoretical background, as shown in Table 1, forming a complete thinking behind the design stages of
In the previous stage, the Fuzzy Delphi Method (FDM) was used to screen out the design elements and design factors considered important by the experts in evaluating consumer needs, and confirm their interdependence

Summary

Introduction

Consumer products refer to products provided for end consumers to use. In recent years, they have been widely used in daily life, from household cleaning and sanitary products, personal products and other general consumer products related to people’s livelihood, to quality goods, clothing, and consumer electronics, with a very wide range, and the output value is even more difficult to estimate [1].Facing the ever-changing global market, companies able to shorten the development cycle and launch new consumer products faster than their competitors gain a larger market share.

Facing the ever-changing global market, companies able to shorten the development cycle and launch new consumer products faster than their competitors gain a larger market share. Fan Miao et al (2005) [2] believed that the implementation of the rapid R&D strategy can give the company an advantage in operation, and make the company a competitor with the ability to respond quickly. In order to avoid the influence of the limit value produced by the traditional Delphi method, the Fuzzy Delphi Method (FDM)
