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.

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.

이 연구는 부정감정인 좌절에 주목하고, 좌절감정을 유발시키는 원인을 탐색하였으며, 좌절한 소비자가 좌절 을 극복하는 과정을 식별하고, 또 제품을 선택하는 경우에 디자인의 심미성 선호도의 제품선택에 대한 영향을 살펴보았다. 연구의 결과는 다음과 같다. 첫째, 좌절은, 실패의 원인이 소비자가 통제할 수 있을 때 느껴지는 분노와 다르게, 목적달성의 실패가 확실하 고 실패의 원인이 소비자가 통제할 수 없는 환경요인에 있을 때 느끼는 것으로 탐색되었다. 둘째, 좌절을 느낀 소비자는, 재도전을 통해 실패상황을 적극적으로 극복하기 보다는, 자신의 실패상황에 대한 감정적 지지와 위로를 가까운 지인으로부터 받아서 실패상황을 감정적으로 극복하려 한다. 셋째, 좌절을 느낀 소비자는 제품의 선택 에서 제품의 디자인이 강조심미성 보다는 조화 심미성을 느끼게 할 때에 더 선호한다. 따라서 마케팅관리자가 좌절을 느낀 소비자에게 자신의 제품을 소구할 때에 제품 디자인에서 강조원리보다 조화의 원리에 의한 접근이 필요하다.

Platform-based product family design is recognized as an effective method to satisfy the mass customization which is a current market trend. In order to design platform-based product family successfully, it is the key work to define a good product platform, which is to identify the common modules that will be shared among the product family. In this paper the clustering analysis using dendrogram is proposed to capture the common modules of the platform. The clustering variables regarding both marketing and engineering sides are derived from the view point of top-down product development. A case study of a cordless drill/drive product family is presented to illustrate the feasibility and validity of the overall procedure developed in this research.
