Affordance is a kind of mental physiology, used by psychologist Donald A. Norman as a design idea, defined as "the property that something can directly and essentially provide something to a person or animal". This idea of returning to the essence and providing properties intuitively has a new guiding effect on product design. The purpose of this thesis is to take the theory of affordance as the basis of design concept, and redesign the shape of desktop lamps in small home appliances, so as to optimize the product shape. A product styling design method based on the concept of affordance is established through four major classifications of affordance, and a styling design scheme is completed using a tabletop luminaire in small home appliances as an example, and then a product styling design evaluation system is used to evaluate the new tabletop luminaire styling design scheme and the existing styling, and the evaluation results are analyzed. Finally, it is concluded that a new product styling design method based on affordance is constructed, and the feasibility and effectiveness of this method are verified, which provides ideas and theoretical basis for product styling design.

Given the huge number of data produced by its users, SNS is a great source of customer insights. Since viral trends in SNS reflect customers' direct feedback, companies can draw out highly meaningful business insights when such data is effectively analyzed and managed. However, while the importance of understanding SNS big data keeps growing, the methods for analyzing atypical data such as SNS postings for business insights over product has not been well studied. This study aims to demonstrate the way to exploit topic modeling method to support marketing strategy generation and therefore leverage business process. First, we conducted topic modeling analysis for twitter data of Apple and Samsung smartphones. Then we comparatively examined the analysis results to draw meaningful market insights about each smartphone product. Finally, we draw out a strategic marketing recommendation for each smartphone brand based on the findings.

This paper presents spatial relationshaps and engineering features for the feature based modeling of Sheet Metal Weld Assemblies (SMWA) that are made of sheet metal components through are welding processes. Spatial relationships in ProMod-S, a sheet metal product modeler,are further extended for the SMWA modeling. Some spatial relationships for special weld joint types are newly introduced. The geometrical and topological relations between spatial reationship, mating features, and assembly features are defined. Finally, assembly data stucturess for the product modeling of SMWA are proposed. They are an engineering relation to represent the constraints between component features, and a mating bond to integrate component design information.

This development has tried to scheme out the convenience for users to use the 3D modeling solution which is developed from the existing programs. The extended 3D modeling solution, to be developed through the use of the API which is provided and Microsoft Access, database is able to reuse the parts, subassemblies of parts, and assemblies. A methodology exhibits the possibility to use a Spinfire Professional Spinfire Reader program. The web evaluation system, which is used to connected with the Internet explorer and to construct a web service, will repeat the evaluations of the company staffs and customers about the new products which the company have designed. The furniture manufacturing company will adopt the 3D modelling solution in modelling the new products and go through the web evaluation system to collect dissatisfied facts of the customers or the company staffs against the new product. Finally, it will contribute to the enormous benefit creation of the enterprise.

Nowadays, there are many efforts to integrate CAD/CAM and other systems. The key of integration is engineering database implementation through the product data definition. In this paper, we suggest the product data definition and their properties for electronic consumer product throughout the requirement analysis for engineering database. Electronic consumer products include electric/electronic parts. as well as mechanical part which mainly compose of machinery. The paper is composed of three parts: the first is analysis about engineering data base. the second is understanding of product data structure and properties. and the last is modeling of product data including static and dynamic characteristics.

One of the most important steps to determine the blank shape and dimensions in deep drawing process is to calculate the surface area of the product. In general, the surface area of axisymmetric products is calculated by mathematical or graphical methods. However, in the case of non-axisymmetric products, it is difficult to calculate the exact surface area due to errors as separated components. Fortunately, it is possible for elliptical products to recognize the geometry of the product in the long side and short side by drafting in another two layers on AutoCAD software. So, in this study, a surface area calculating system is constructed for a design of blank shape of deep drawing products. This system consists of input geometry recognition module and three dimensional modeling module, respectively. The suitability of this system is verified by applying to a real deep drawing product. The system constructed in this study would be very useful to reduce lead time and cost for determining the blank shape and dimensions.

Recently, due to emerging technologies such as radio frequency identification(RFID), global positioning system(GPS), and wireless mobile communication technologies, it is possible to build up the infrastructure for tracking and tracing product logistics data at any place and at any time. However, for implementing the infrastructure, it is necessary to develop a suitable management method for product logistics data. To this end, this study deals with a resource description framework(RDF) based modeling and application method for product logistics data in the ubiquitous environment. It will give us the capability to control product logistics data, which leads to streamline logistics operations.

As a product structure or BOM(bill of material) of products is hierarchically structured, the design based on the concept of relational data base modeling causes low performances in data search or processing. For this reason, an object-oriented approach to designing a product structure is proposed in this paper. Using Rumbaugh's OMT (Object Modeling Technique) method, classes of parts, BOM structure, options, and models are defined and their class-relationship diagrams are proposed. For the representation of the BOM structure suitable for the object-oriented paradigm, a new data architecture called the BOM item class is suggested. It is expected that the proposed data structure ensures better reusability and expandability due to the modularity.

CAD를 이용한 제품의 설계는 전체적인 제품개발공정의 효율성에 있어 핵심적인 역할을 하고 있다. 따라서 설계자가 어떻게 제품을 모델링 하느냐에 따라 모델의 품질이 달라질 수 있으며 이는 이후에 진행되는 하위 공정의 효율성에 지대한 영향을 끼치게 된다. 이에 본 논문에서는 모델의 품질을 향상할 수 있는 모델링 교육 시 강조하여야 할 3가지 개념을 제시하였다. 이러한 개념을 대학에서의 CAD교육에 적용함으로써, 작게는 모델의 변환과정에 소요되는 시간 및 노력을 현저히 감소시키고, 나아가 제품개발공정의 효율성향상과 동시에 궁극적으로, CAD와 CAM같은 서로 다른 도메인간의 통합에 긍정적인 영향을 줄 것으로 기대한다.

Most recently, offshore Engineering & Construction field is concerned about integration management technology such as CIM(Computer Integrated Manufacturing), PDM(Product Data Management) and Enterprise Information Engineering in order to cope with the rapid change of engineering and manufacturer specification as per owner's requirement during construction stage of the project. System integration and integrated data modeling with relational database in integration management technology improve the quality of product and reduce the period of the construction project by reason of owing design information jointly. This paper represents the design methodology of system integration using Business Process Reengineering by the case study. The case study is about the offshore plant material information process from front end engineering design to detail engineering for the construction and the basis of monitoring system by integrating and sharing the design information between the 2D intelligent P&ID and 3D plant modeling using relational database. As a result of the integrated data modeling and system integration, it is possible to maintain the consistency of design process in point of view of the material balancing and reduce the design assumption/duration. Near future, this system will be expanded and connected with the MRP(Material Requirement Planing) and the POR (Purchase Order Requisition) system.
