Developing Product Design Requirements Using Kano Model

The selection of a design for the given product is a critical problem in product design development. Focuses of the designers and customers on the design are not identical. In order to bridge the gap and provide a more relaxing way to select the design, a new method based on quality function deployment (QFD) is proposed. In such a method, customers are required to give their linguistic preferences on the design with respect to the customer requirements (CRs). In the rating of the weight of CRs, they are allowed to provide incomplete linguistic weight information and the objective optimization model is proposed to derive the exact linguistic weight information. Designers are required to rate the correlation between design requirements (DRs) and the relationship between the CRs and DRs to construct the house of quality. Opinions given by the customers are translated into the opinions with respect to the DRs based on the QFD. Afterwards, the priorities of the designs and design requirements are determined. The assessment results not only show the contribution of each design requirement to the customer satisfaction but also show the advantages and disadvantages of each design from the designers’ perspective clearly and directly. An example is provided to validate the applicability of the proposed method.

Industry Needs

With the threat of global warming nowadays in the 21st century, the European Union has set the standard “Eco-Design Requirements for Energy-using Product(EuP)” for controlling the development of consumptive electronic machinery and products. Therefore, the trend of green design sees the instruction of EuP as the main direction for energy-saving. Considering the factors, undergoing the comprehensive evaluation and development process, the industry needs to draw up the corresponding design strategy in response to the new situation. Therefore, to optimize the green design strategy, the designers can replace hardware with the intelligent system to develop more optimal energy-saving products. Following the ecological instructions of energy-saving of EuP as direction, this study combined the advantage of the intelligent system and green design in order to optimize strategy of green design on intelligent energy-saving product under eco-design requirements for energy-using product (EuP). The evaluation factors were included in the strategies of intelligent energy-saving product design by analyzing the product users’ cognition, needs, habit and etc. Furthermore, through the Fuzzy Analytic Hierarchy Process (FAHP), the priority and the important factors of green design were analyzed. By examining the green design strategy on energy-using product, industry needs to think the energy-saving conditions and the key factors on deciding process. Eventually, the efficiency of product design for environment can be fulfilled successfully.

Design is a challenging task that is crucial to all product development. Advances in design computing may allow machines to move from a supporting role to generators of design content. Generative Design systems produce designs by algorithms and offer the potential for the exploration of vast design spaces, the fostering of creativity, the combination of objective and subjective requirements, and the revolutionary integration of conceptual and detailed design phases. The application of generative methods to the design of discrete, physical, engineered products has not yet been reviewed. This paper reviews the Generative Product Design systems developed since 1998 in order to identify significant approaches and trends. Systems are analyzed according to their primary goal, generative method, the design phase they focus on, whether the generation is automatic or interactive, the number of design options they generate, and the types of design requirements involved in the generation process. Progress using this approach is recognized, and a number of challenges that must be addressed in order to achieve widespread acceptance are identified. Possible solutions are offered, including innovative approaches in Human–Computer Interaction.

Abstract Professionals perceive product design as an essential factor in product competitiveness, especially in international markets. To achieve that, customers and buyers must accept the quality of the offered product design. Especially by mass-produced products are producers facing a lot of customers with limited knowledge about design requirements. Appropriate communication is necessary to persuade potential customers about design quality characteristics. Paper utilizes previously formed customer classification based on quality perception. It discusses the possibility of applying such classification for product design perception too. Different methods and tools to prove the relevance of the presented model are analyzed to form an optimal model for future research. The result of such research would be the optimization of the use of product design in communication strategy.
