  • A case study bas been conducted to explore design activities of four expert designers through protocol analysis, We examined relations among design information, process patterns and solution qualities with two complementary coding schemes based on design contents and design process, Relation between personal creativity modes and design activities has been examined as well. Regarding design process, an adequate distribution of activities in process may be necessary to bring out a good solution. It seemed that the more design contents about context, external knowledge, and general feature are used, the more unique design concepts are made. Regarding personal creativity modes, not much of differences in that design activity were observed while only a few relations between designer's personality and design activity were observed. The fact that the designers participated are all experienced designers could explain this. Investigation on the differences between novice designers and expert designer reflected in protocol data based on design information and design process coding scheme is to be done. Also, how personal process patterns observed through this protocol analysis can be utilized in composing design team.

  • The objective of design process modeling is a systematic support of rapid redesign process fur a modified input data. The design process modeling is realized by storing key parameters or geometric entities used in the intermediate design steps and reusing them for change of the designed parts or assemblies according to the modified input. In this paper, we adopted and implemented the design process modeling approach to our injection mold design system developed based on the Unigraphics system. It was proved that the productivity of mold redesign process is raised highly by introducing the design process modeling technique mold design system.

  • The design of multi-stage gear drives is a time-consuming process that includes additional design problems, which are not considered in the design of single-stage gear drives. In the previous research works, the authors have proposed a new algorithm to design multi-stage gear drives at the preliminary design phase. The proposed design algorithm automates the design process by integrating the dimensional design and the configuration design process. In the configuration design process, the positions of gears and shafts are determined by minimizing the geometrical volume (size) of a gearbox. However, various types of spatial constraints should be satisfied in practical design situation. To locate input and output shaft in specified positions is the typical example of such problems. In this paper, the authors show the formulations of spatial constraints applied to the design of four-stage gear drives. The design solution shows considerably good results, and the design system is confirmed to be readily applicable to practical design situation.

  • Preconstruction process in a lean project delivery system was studied in one large healthcare project working for a general contractor. Researchers joined a new lean delivery project for approximately six weeks and participated in preconstruction process including design coordination, management coordination, and target costing while concurrently interviewing other project participants and employees, recording activity in meetings, and otherwise observing the process. The preconstruction process in lean project delivery system, called integrated project design, showed many benefits such as brining expertise of downstream players (i.e., mechanical and electrical contractors) into the design phase. However, lack of leadership and lack of design-integrator blocked the successful application of a new concept of design process.

  • A simple design process is proposed for supplemental viscous dampers based on structural safety redundancy. In this process, the safety redundancy of the primary structure without a damper is assessed by the capacity and response spectra. The required damping ratio that should be provided by the supplemental dampers is estimated by taking the structural safety redundancy as a design target. The arrangement of dampers is determined according to the drift distribution obtained by performing pushover analysis. A benchmark model is used to illustrate and verify the validity of this design process. The results show that the structural safety redundancy of the structure provided by the viscous dampers increases to approximately twice that of the structure without a damper and is close to the design target. Compared with the existing design methods, the proposed process can estimate the elastic-plastic response of a structure more easily by using static calculation, and determine the required damping ratio more directly without iterative calculation or graphical process. It can be concluded that the proposed process is simple and effective.

  • The design process of a relational database system consists of requirement analysis, conceptual design using ER diagram, logical design, and physical design. In logical design process, the conceptual schema is transformed to relational schema, and relational schema is normalized. This traditional design process is hard to applied in real database design process, since there is an ambiguity in conceptual design process. In this paper, we suggest a new design process, which provides more structural design steps by removing the conceptual design process. In new approach, we produce the data flow diagram by the structural methodology. From the attributes in the data store of data flow diagram, we construct relational table schema, and we normalize relational schema. Finally we produced table relationship diagram in order to figure out relationships between tables.

  • The user participatory design process collects users' opinions efficiently through a feedback process such as various user workshops and conferences. When users who actually participated in a design process use the facility in which they were a participant, their satisfaction with the design quality of the facility they use may be enhanced; therefore, user participatory design methods in school construction are deemed to enlarge consistently the interest in a school of students, parents, teachers, and local residents. This paper selected the most appropriate user participatory design methods through an analysis of actually applied cases, and applied them to the empirical exploration process. Also, problems incurred through the empirical exploration process were solved by various user participatory design methods based on actually experienced cases and the results of workshops performed. As such, this paper deduced problems by applying user participatory design methods in practice, and solved problems by executing the empirical exploration process again. Through this, the paper proposed a variety of user participatory design methods for improving school design and raising user satisfaction.

  • The knitwear industry requires ways to satisfy a changing environment. This study suggests a knitwear design process using a knit CAD program. Such a process needs to implement a CAD system that develops a sufficient knit design system to advance the knitwear industry in both planning and manufacturing. In order to contextualize this research, this study reviewed the current state and problems of the knitwear industry and the market, and investigated the actual condition in which the CAD system is used in knit design by CAD system service providers. The findings of the study are as follows: First, All brands had individual ways to reduce the amount of lead-time. The knit designers pointed out that any given sample product is made in the form of a swatch; after the knitting step and prior to the manufacturing process. In women's wear brands, basting was inserted into the production process in order to reduce the amount of sample losses. Second, a CAD program enables the uses of swatches to see the adequacy of yams, textures, and style that simulate the completed style. Third, this study examined the efficiency of knit design process conducted by the knit design CAD system based on expert assessments, showing that the use of a knit CAD program in commercial knit design proved to be more efficient than in previous models.
