The purpose of this study is to examine how similarities between product designs manifest themselves in various aspects and how these influences purchasing and usage behavior. Product design similarity evokes positive images, such as a sense of security and familiarity, as well as negative images, such as mimicry and copying. For example, if you have just transferred to another school and your uniform does not match everyone else's, you might feel alienated. On the other hand, in parks and on street corners, wearing the same clothes and belongings can lead to an awkward moment. In the realm of psychology, the former is called the bandwagon effect and the latter is the snob effect. In contrast to the snob effect, which emphasizes scarcity, the bandwagon effect can create fads and hits. People experience both of these emotions, and it is said that using them appropriately and combining them leads to an effective marketing strategy.

In this study, We designated the injection molded plug housing for charging electric vehicles as a research subject. And we analyzed the effect of Rib design on the quality of injection molded products. First, we used the Taguchi method to derive optimal conditions for rib design. The factors were set as the Thickness of the rib, the Height of the rib, and the Radius of the rib. Each factor consisted of 5 levels and generated conditions for a total of 125. We performed an injection molding analysis and confirmed significant factors affecting the deformation of injection molded products through ANOVA. Based on this, the 25th design detail was selected as the optimal condition. In addition, We compared the results of the molding analysis with the molded products that did not design ribs. We confirmed that the molded product designed with ribs under optimal design detail improved the deformation amount by 22.22% and the residual stress by 8.35%, compared to the molded product not designed with ribs.

A manufacturing company should produce its products and make a profit to continue its management. With the adoption of a multi-category small-volume production system, manufacturers that produce concrete pump-cine products are carrying out improvement activities to increase their market share amid the business-to-customer business environment. However, the slump in the construction investment environment has led to a decline in sales of concrete pump trucks. The purpose of holding inventory is to prevent loss of sales opportunities with the rate of change in the sales plan, and reducing the rate of change in the product can reduce unnecessary inventory and, in order to realize this, the goal of reducing inventory can be achieved by reviewing the parts that can be designed for common use. Therefore, to reduce the inventory of concrete pump trucks, semi-finished publicization design is necessary. According to the analysis, the frame assembly process of the 32M model is common. Production capacity can be secured without loss of sales opportunity.

The purpose of this study is to provide the priority of the front-loading factors in the design stage of the automotive parts development process in order to efficiently and effectively respond to the demands of the car maker (customer). Front-loading is defined as a strategy in order to improve development performance by shifting the identification and solving of design problems to earlier phases of a product development process. Two approaches of the front-loading are project-to-project knowledge transfer and rapid problem solving. For the study, a survey was conducted on the R&D department in the automobile parts company and analyzed by AHP (Analytic Hierarchy Process) method. The result of the survey shows the cost savings is the highest weight in terms of front-loading effect and in terms of front-loading factors, it gives priorities as “the problems of past project” first, “Design Review” second, “CAE (Computer Aided Engineering)” third, “FMEA (Failure Mode and Effects Analysis)” fourth, “benchmarking” and SR (Sourcing of Requirements). The results of the study will be helpful to provide practical value for improving product design of component development.

Judging by the volume of marketplace failures, it seems that consumer innovators make biased assessments about the value of the innovativeness of new products (Gourville, 2006; Mugge & Dahl, 2013). Research suggests that consumer evaluate offerings based on form (i.e. visual appeal) and function (i.e. utilitarian appeal) (Gourville, 2006; Talke, Salomo, Weiringa & Lutz, 2009; Mugge & Dahl, 2013). In relation to innovative new products, the consumer decision-making path is unclear and the optimal mix of continuity and discontinuity across form and function is unknown. The lack of information regarding how marketers should appropriate resources to maximise returns thus, is an issue that requires resolution. To help resolve this gap, we seek to address two important practical marketing questions in the context of innovative new product introductions: (Q1) What is the impact that discontinuity and continuity across form and function have on new product adoption, and (Q2) What if any, are the underlying mediating mechanisms for different markets? To address these, we collected data from participants based in the United States of America through an online experiment. The participants were presented with four products, comprising variations of a digital camera based of continuity and discontinuity across form and function. The findings revealed that the same product could lead to differing perception of value based on the participant being an innovator or an adapter. The differing perceptions were explained by differences in assessments of potential costs and benefits from the product. Based on the findings of the study managerial recommendations on targeting the right segment for the right product were offered.

Introduction For a long time, firms have been improving product function, performance, price-performance ratio (hereinafter uniformly referred to as functional aspects of product design), and product appearance. Nevertheless, the current market situation is that many products in the same category are similar in quality, price and appearance. Product homogeneity leads to excess supply, and this situation is objectively long-standing. For consumers, positive emotions often play a key role in their purchase decisions. Yet, when most products seem to be similar, it is difficult to evoke more positive emotions of consumers to increase their willingness to pay. This paper shows that besides product appearance and functional aspects of product design, the connotations of product aesthetics should also be focused. In other words, aesthetic aspects of product design should include both product appearance and connotations. Connotations, as deep meaning inside product aesthetics, can evoke either consumers’ memories of the past or imagination of new creative ideas, or both (e.g., Starry night umbrella by MoMA Design Store, Sakura Masking Tape by Bande). Although the contents of memory recall or imagination might differ across consumers, positive emotions evoked in that process will increase willingness to pay. A new conceptual model is proposed in this paper, which shows that functional aspects, product appearance, and the connotations of product aesthetics could cause different psychological activities, and positive emotions evoked in those processes can enhance willingness to pay. When most products tend to be similar, the connotations of product aesthetics could be a promising area for firms today to make their products distinctive and increase their market share. Product Design and Consumer Emotions (1) Elements of Product Design Product design is considered as the set of properties of a product, including both functional and aesthetic aspects (e.g., Homburg, Schwemmle, & Kuehnl, 2015; Jindal, Sarangee, Echambadi, & Lee, 2016; Luchs & Swan, 2011). Functional aspects of product design consist of function, performance, and price-performance ratio. Aesthetic aspects mainly refer to product appearance, consisting of visual elements such as color, shape, and material. (2) Relationship between Product Design and Consumer Emotions Previous research shows that functional aspects of product design could evoke positive emotions like satisfaction, and aesthetic aspects could please our senses and make us feel delight (e.g., Bloch 1995; Chitturi, Raghunathan, & Mahajan, 2008). Furthermore, Norman (2004) points out that emotional factors can be the key to the success of product design. If a product could evoke consumers’ positive emotions, those emotions would arouse willingness to pay. If not, consumers might not have the desire to buy it. The Connotations of Product Aesthetics Evoking Positive Emotions of Consumers As Barnard (2005) suggests, as the deep level of meaning, connotations refer to one’s feelings or thoughts caused by a design. This paper proposes that the connotations in product aesthetics could either remind consumers of their past experiences or trigger their imagination to think about new creative ideas, or both. Emotional resonance could be achieved and finally facilitate purchase behaviors. In our daily lives, there are many products that have not only beautiful appearances but also the connotations of product aesthetics. For instance, Starry Night Umbrella by MoMA Design Store (Figure 1). MoMA Design Store released an umbrella patterned with stars, the moon and the sky that swirl, which reminds consumers of the masterpiece The Starry Night (1889) by Vincent Van Gogh. When encountering this umbrella, consumers who love the works of Van Gogh will have positive emotions and a strong desire to buy it. Cherry Blossom Masking Tape by Bande (Figure 2). Bande, a Japanese masking tape brand, launched a masking tape with sakura (cherry blossom in Japanese) petals design. Its real-like floral design can remind consumers of spring or their own stories with cherry blossom and trigger their imagination to come up with lots of creative ideas such as using it to decorate their diaries, laptops, furniture, and so on. Besides the original function of tapes, the connotations inside product aesthetics could encourage consumers to think creatively and feel happy. A Conceptual Model of Product Design, Positive Emotions, and Market Share This paper proposes a conceptual model (Figure 3), showing that different aspects of product design can evoke consumer emotions and those positive emotions have a positive effect on willingness to pay. First, functional aspects of product design are very important. Consumers compare function, performance, and price-performance ratio among many products, which is considered as a process of rational thinking. Products with high qualities and affordable prices can make consumers feel satisfied. Positive emotions (E1) evoked by functional aspects can enhance the willingness to pay and bring firms market share (S1). Then, on the bases of functional aspects, firms use different colors, shapes, and materials to make product appearance attractive. Sophisticated appearances of products can please the senses of consumers and evoke positive emotions (E2). That could increase their desires to buy and bring more market share (S2) for firms. Nevertheless, these two parts are what most firms can do today. To make products distinctive, firms should add connotations into aesthetic aspects of product design, which can trigger consumers’ memory recall of their past experiences or their imagination of new creative ideas, or both. Although the contents of recall and imagination are different across consumer, the arousal of positive emotions (E3) will enhance willingness to pay and finally bring new market share (S3). Thus, two equations derived are as follows: Positive Emotions = E1+E2+E3 Market share =S1+S2+S3 If firms take all these aspects of product design into consideration, their products will evoke consumers’ positive emotions adequately to increase willingness to pay, and help firms occupy more market share from fierce market competition. General Discussions On the market today, lots of products have beautiful appearances and seem to be similar in functional aspects of product design. To make products distinctive, this paper considers that firms should also attach importance to the connotations of product aesthetics. The connotations will remind consumers of their past experiences or let them imagine new creative ideas, or both. Positive emotions evoked during that process increase willingness to pay. That is a promising area for firms today to gain more consumers and new market share. Since the connotations of product aesthetics could be influenced by factors such as age and culture, it is important for marketers to investigate and analyze consumers’ understandings of aesthetics from different ages and cultures, then feed it back to designers to help them design successful products in the future.

While product design is intrinsically linked to brand building and to the definition of luxury, consumers’ sensitivity to luxury products and to design is usually addressed separately. Yet, for optimal marketing-oriented decisions, they need to be brought together. Furthermore, while design is intrinsically linked to luxury, little research focused on its influence on the symbolic and the economic value of brands. This research specifically delves into the mechanisms behind how brand-level attitudes can be influenced by product-level sensitivity to product design. Building on the value theory, it investigates to what extent the product design enhances luxury brands value. Based on a data set collected on 125 individuals, a partial least square analysis was used. It contributes and extends literature on branding, design and luxury in three distinct ways. Firstly, this research distinguishes two antecedents of the product design that are the social and the individual drivers. Secondly, it reveals the mediating role of the product design between social and individual drivers, on one hand, and luxury brands symbolic value (through brand love and brand equity), on the other hand. Thirdly, it confirms the creation of economic value through the positive influence on willingness to pay a premium price. In terms of managerial implications, this study reveals the importance for luxury brands to develop sensory branding through product design. It especially points out the added-value of design for luxury brands’ equity, its role in fostering brand love and in increasing luxury brands turnover.

The purpose of this study was to identify the consumers’ demands on functional design of sports climbing pants. Data were collected through a field survey. 82 male and 70 female amateur sports climbers in Seoul participated. The questionnaires measured aspects of functional design in sports climbing pants, specifically motion adaptability, comfort and aesthetic value of the climbing pants. The results of this study show that comfort during climbing postures was the most important value of the climbing pants. The subjects sought motion adaptability at the hip, crotch, thigh and knee. The preferred style and degree of fit of climbing pants were differed according to gender. Men preferred loose or semi tight fit style climbing pants but women preferred the leggings style of the sport pants. The soft touch seam line and body shaping function were also important for women. The type of pants preferred for sports climbing also differed by the climbing experience period. Men began to wear the outdoor mountaineering style pants when they had experienced sports climbing for 6 months and to wear the climbing expert style pants when they had experienced sports climbing for a year. Most women wore leggings style sports pants from the beginner stage. This study also analyzed Korean market trend in 2016~2017 F/W for sports climbing pants design. The men’s pants were more likely to be designed to improve mobility compared to the women’s pants, even though the aesthetic value of the sports climbing pants was important for women.

Recently, Product-Service System(PSS) is a rising paradigm that enables integration between products and services offering. Also, academic interests for product-service design using the house of quality (HOQ) have been emerged. the engineering characteristics of the HOQ are usually extracted by experts. However, as the new technologies were merged, it was difficult to find the optimum expert for extracting the engineering characteristics in the fusion technology. Therefore, this paper applies the topic modeling technique using patent data to extract the engineering characteristics which considers not only products features but also services characteristics. Also, a case study demonstrates the usefulness of our approach with augmented reality-head mounted display. It was conducted to make the HOQ with distinct four steps. First, the customer needs were collected through the latest device review from website and grouped into the representative customer needs. Second, the engineering characteristics of the augmented reality-head mounted display were extracted by using the US patent data of augmented reality head mounted display through the topic modeling technique. Third, the correlation degree of product - service characteristics was drawn by using the extracted topic’s cosine similarity. Finally, the relationship matrix of customer needs and engineering characteristics was filled with experts. After which we suggest product-service business concepts from HOQ. Main advantage is appeared from the result of this research paper is that it can provide the business concepts of the integrated product-services to reflect the customer requirements. This business concepts are utilized for the early phase in R&D planning.

This study proposes a methodology to analyse social networks among participating design engineers during product development projects. The proposed methodology enables product development managers or the participating design engineers to make a proper decision on product development considering the performance of participating design engineers. It considers a product development environment where an integrated product data management (PDM) system manages the product development data and associated product development processes consistently in its database, and all the design engineers share the product development data in the PDM database for their activities in the product development project. It provides a novel approach to build social networks among design engineers from an operational product development data in the PDM database without surveys or monitoring participating engineers. It automatically generates social networks among the design engineers from the product data and relationships specified by the participants during the design activities. It allows analysts to gather operational data for their analysis without additional efforts for understanding complex and unstructured product development processes. This study also provides a set of measures to evaluate the social networks. It will show the role and efficiency of each design engineers in the social network. To show the feasibility of the approach, it suggests an architecture of social network analysis (SNA) system and implemented it with a research-purpose PDM system and R, a statistical software system. A product configuration management process with synthetical example data is applied to the SNA system and it shows that the approach enables analysts to evaluate current position of design engineers in their social networks.

Trends of integrating products and services lead to the emergence of Product-Service System (PSS). To implement and embody a PSS solution in new product development, a comprehensive design framework is allowed designers to facilitate the design factors of the PSS in complex business environments. A physical product, containing functionalities for services, is the role of medium between customers and a manufactures. Customers can access those metaphysical interfaces to utilize the product fully or expand its performances. The PSS is aiming to prolong its lifecycle while maintaining its expected quality. Since the quality can be represented as a measure which belongs to user’s perspective, guaranteeing certain level of quality can be interpreted to sustaining customer satisfaction. The objective of this paper is to propose a PSS design framework to identify design factors for developing products and services by integrating object-oriented concepts and blueprinting in context of a business ecosystem. The proposed model is developed based on relationship products and services matching with their design factors. The products and the services are then brought together to form a PSS. Functions and processes can be categorized to identify the design factors in different levels using the object-oriented concepts. Objected-oriented concepts provide PSS analysis tools for describing a business process or a workflow process in the PSS. The blueprint is used to identify the relationships between the products functions and the service processes that are offered as part of a job. To demonstrate of the effectiveness of the proposed model, we use a case study involving a smart phone.

The purpose of this study is to develop a design as a high value-added exportable industrial product by developing a cultural product, that can be accepted as having universal beauty by people in the Western cultural area. This is done by, re-analyzing it from a modern perspective after applying the color representation, used in pop art, to Shin Saimdang’s Chochungdo (草蟲圖, insects on flowers) which clearly expresses Korea’s national emotion and aesthetic consciousness. The research method depends upon developing cultural products such as scarfs, neckties, handkerchiefs, and folding fans, which are communicated in the global market The expressive technique of pop art is utilized after reconstructing the color sensation of pop art in the aesthetic dimension of the natural, physical, and formative beauty of Chochungdo based on the whole understanding of our country’s genre of Chochungdo and Western pop art. With regard to the colors in the developed design, the basic colors were extracted and applied by selecting 10 pieces in the flower series, which were made with the silkscreen printmaking technique in the 1970s by Andy Warhol, a master in pop art. A work that integrates pop art, a global art trend, with Korean traditional culture is expected to highlight Korean traditional culture in the global cultural era.
