“…There are 900 type-1 d values in the sample bank. After performing calculations and obtaining statistics according to Equations (11) and (12), the distribution of these d values is shown in Figure 11a. According to the statistics, 90% of the data are less than 0.91.…”

“…From the prediction of Kumar et al [10], the similar feature descriptions extracted from historical models could be used to predict the vehicle design trend. Cluzel et al [11] encoded automobile silhouettes connected by several feature lines to obtain their quantitative modeling feature data. In line with this idea, Hyun et al [12] proposed a new algorithm to extract feature lines from the body profile of each car in their further research, and calculated the similarities and differences among several models based on this line data.…”

In this paper, a new parameterized surface, termed SQ-Coons surface, is proposed according to the build mode of Coons patch. The surface is always interpolated to the boundary curves, and its shape details could be controlled by the shape parameters in CE-Bézier basis functions, which makes it suitable for styling design in computer aided design (CAD). In order to exert its geometric advantages in car design, a simplified body CAD template based on characteristic lines is built according to common vehicle features. The template is built entirely from SQ-Coons surfaces, so that the overall style and detail shapes could all be modified by the control points and shape parameters of each surface. By analyzing the curvature of fifty commercial car types generated through the template and various parameters, a set of methods for constraining the range of shape parameters is proposed. On this basis, as an example, the four shape parameters of the hood surface in one model are used as variables to optimize the body shape to achieve the lowest possible aerodynamic drag coefficient in computational fluid dynamics (CFD). The results show that the design method, combining the new surface and the model template, could reflect the modeling characteristics of different cars, and improve the design and scheme adjustment efficiency in the conceptual design stage.

“…A car is a representative example of a mature product. Car profile, which is a concentrated expression of the car form and provides a rich form language of car design, is receiving increasing emphasis in consumer car choice; considerable research has been conducted on this topic [18][19][20][21]. Therefore, this study adopts a car profile case to demonstrate the proposed method.…”

“…When implementing KES studies, the products are usually decomposed into design variables [16,17]. The design variables can be discrete variables such as the type of design components [18,19] and can also be continuous variables such as the coordinates of the feature points on the contour [20,21]. The result of KES study can provide deep insight for design.…”

Affective responses concern customers’ affective needs and have received increasing attention in consumer-focused research. To design a product that appeals to consumers, designers should consider multiple affective responses (MARs). Designing products capable of satisfying MARs falls into the category of multiobjective optimization (MOO). However, when exploring optimal product form design, most relevant studies have transformed multiple objectives into a single objective, which limits their usefulness to designers and consumers. To optimize product form design for MARs, this paper proposes an integrated model based on MOO and multicriteria decision-making (MCDM). First, design analysis is applied to identify design variables and MARs; quantification theory type I is then employed to build the relationship models between them; on the basis of these models, an MOO model for optimization of product form design is constructed. Next, we use nondominated sorting genetic algorithm-II (NSGA-II) as a multiobjective evolutionary algorithm (MOEA) to solve the MOO model and thereby derive Pareto optimal solutions. Finally, we adopt the fuzzy analytic hierarchy process (FAHP) to obtain the optimal design from the Pareto solutions. A case study of car form design is conducted to demonstrate the proposed approach. The results suggest that this approach is feasible and effective in obtaining optimal designs and can provide great insight for product form design.

This paper proposes a support system for logotype design based on impression of a target logotype. The presented system has the impression estimate part, the logotype generation part and the logotype modification part. Especially, this paper describes the roles of the impression estimate part and the logotype generation part, and the procedure of generating an initial logotype design. Impression of a target logotype, which is expressed using an adjective, and a character string are inputted to the system. In the impression estimate part, the inputted adjective is analyzed by the concept of co-occurrence of adjectives and its impression value is obtained. The logotype generation part has an impression space that expresses a factor structure of impression of a logotype, which is obtained by factor analysis of data in the pre-experiment. This part generates logotype candidate that has the lowest degree of dissimilarity of the impression value among impression values of logotype samples in the impression space comparing with the impression value of an inputted adjective. The results of the subject experiment show that the initial logotype design generated by presented method reflects the inputted impression well.
