The Part Count Tool (PaCT) for Design Concept Selection  [PDF]
Tarang Parashar, Kerry Poppa, Katie Grantham Lough, Robert B. Stone
Modern Mechanical Engineering (MME) , 2011, DOI: 10.4236/mme.2011.12003
Abstract: This paper presents a part count tool that predicts the part count for a particular product concept during the conceptual design phase. The part count tool will also aid in ranking the design concepts by the criterion of number of components for a product. This tool utilizes existing automated concept generation algorithms to generate the design concepts. It extracts the available data from the Design Engineering Lab Design Repository to determine an average number of parts per component type in the repository and then calculates an average part count for new concepts. The part count tool also uses an algorithm to determine how to connect two non-compatible components through the addition of mutually compatible components. While emphasis is placed on the average parts per product in evaluating designs, the overall functional requirement of the product is also considered.
A Combined Probabilistic and Optimization Approach for Improved Chemical Mixing Systems Design  [PDF]
Matthew J. Opgenorth, William E. McDermott, Peter Laz, Corinne S. Lengsfeld
Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.36077
Abstract: A design analysis of a mixing nozzle was performed using a combination of probabilistic and optimization techniques. A novel approach was utilized where probabilistic analysis was used to reduce the number of geometric constraints based on sensitivity factors. An optimization algorithm used only the most significant parameters to maximize mixing. A second probabilistic analysis was performed after optimization was com-plete in order to quantitatively predict the effects of manufacturing tolerances on mixing performance. This process for automated design is attractive over full parameter optimization techniques due to the computa-tional efficiency resulting from an intelligent reduction in evaluated variables.
Probabilistic Simulation Approach to Evaluate the Tooth-Root Strength of Spur Gears with FEM-Based Verification  [PDF]
EL-Sayed S. Aziz, Constantin Chassapis
Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.312142
Abstract: Dependency on deterministic design techniques without attention to inherent process variations and uncertainties in gear design and manufacturing processes can lead to unreliable results and affect the performance of a gearing system. A better understanding of the impact of uncertainty associated with the system input on the system output can be achieved by including reliability techniques to accomplish a reliable design methodology. This emerged the need to consider the probabilistic behavior of the stress distribution on the gear tooth during the design phase. The present effort reports on the application of the SSI theory within the context of a “Design for Reliability” approach in support a detailed gear design methodology for the evaluation the tooth-root strength with FEM-based verification. The SSI theory is formulated to predict the effect of the root fillet generated by a rack or hob tool with and without protuberance on the gear system reliability. The results obtained from the probabilistic analysis strongly agreed with the FEM’ results across a range of different gear tooth fillet profiles. A quantitative assessment of the investigated gear sets showed the highest tooth-root stress was associated with the lowest tip radius of the generating tool. This approach helps with making the decision by quantifying the impact of stress and strength variations during the gear design stage.
A Study on the Conceptual Design of Fashion Product  [PDF]
Yue Hu, Ying Liu
Art and Design Review (ADR) , 2017, DOI: 10.4236/adr.2017.54020
Abstract: In today’s increasingly fashionable design society, the design of fashion products requires designers to have advanced consciousness and innovative spirit. Concept design is undoubtedly the most consistent with the development trend of the field of design theory. However, related studies are still scarce. This paper explains the definition of conceptual design and the conceptual design features of fashion products. Furthermore, some principles and methods of carrying out conceptual design of fashion products are analyzed preliminarily, with a view to further theoretical framework of fashion product conceptual design and its methods, to provide guidance for the development of design activities.

Yen Hsu
American Journal of Industrial and Business Management (AJIBM) , 2013, DOI: 10.4236/ajibm.2013.31002

Managers at NPD departments of Taiwan consumer electronic industry were interviewed to explore the effects innovation strategy (IS) has on design strategy (DS) and finally on product design characteristics (DC). The fitness of theoretical models and the observed data was examined. A questionnaire survey was conducted. 1300 enterprises in Taiwanconsumer electronic industry were randomly selected as the survey pool. At last, 370 effective questionnaires were collected. Their responses on the questionnaires were analyzed to test the fitness of the model with structural equation modeling analysis (SEM). A proper fitness was found for the correlation theoretical model of IS, DS, DC, and the observed data. In enterprises, IS will influence product DC, and at the same time, IS will influence product DC through DS. Among these three variables, DS serves as an independent variable and intervene variable to DC.

Explaining Design Dimensions of Ecological Greenways  [PDF]
Mohammadreza Pourjafar, Amir Moradi
Open Journal of Ecology (OJE) , 2015, DOI: 10.4236/oje.2015.53007
Abstract: Design of greenways is one of the most important planning tools in the promotion of quality of life of the city residents. Greenways are necessary due to their major role in increase of air quality and positive changes in the climate of the urban environments for keeping the environmental quality of the cities and considerably increasing aesthetic values of these environments. Protection of natural ecological systems, provision of extensive recreational opportunities for people in urban regions and rural districts, provision of economic benefits and protection of cultural values and historical heritage are the advantages of designing and creating greenways inside cities. The present paper which was conducted with descriptive-analytical method tried to explain design dimensions of ecological greenways in three urban physical, environmental and social-economic systems by studying suitable experimental concepts and samples in the world. In this regard, this paper studied five main goals of designing greenways: promotion of local and urban accesses with greenways, aesthetic aspects of urban landscapes, improvement of performance and distribution of activities by creating greenways, increase of efficiency and environmental aspects in the city and revival of social values considering economic sustainability and in this regard design strategies and policies were presented for each one of them based on these goals.

Categorization and Features of Simplification Methods in Visual Design  [PDF]
Chun-Cheng Hsu, Wei-Yao Wang
Art and Design Review (ADR) , 2018, DOI: 10.4236/adr.2018.61002
Abstract: Simplification is a very important graphic design method used by designers to make graphics more memorable and immediately recognizable, and is utilized in logos, symbols, posters, computer icons, and other design applications. The purpose of this study is to investigate the categories and features of simplification in graphic design. A review of relevant literature and a focus group technique are the main methods used in this research. The conclusion revealed that graphic simplification modes may be divided into extraction of the complete form and extraction of partial features. The former can be further divided into 1) rendering external outlines, 2) preserving structural relationships, 3) flattening, and 4) simplifying geometry. The latter can be divided into 1) emphasizing visual features, 2) emphasizing functional features, and 3) preserving surface patterns. This study also discusses and compares the features of these methods as used in design teaching and practical design.
“I’m Just Guiding You”: An Exploration of Software Design Mentorship within a Software Engineering Firm  [PDF]
Leshell Hatley, Maha Al-Freih, Brenda Bannan
Journal of Software Engineering and Applications (JSEA) , 2018, DOI: 10.4236/jsea.2018.116019
Abstract: The case study presented here uses an interpretivist (qualitative, humanistic) approach to illustrate and describe a range of interactions and behaviors that occur during design meetings where mentoring and design simultaneously occur within a software engineering firm, during a portion of the design phase for a software project. It attempts to examine the interaction between two design team members (one novice and one expert) and describes how these observations intersect with the theoretical and applied literature and actual design processes. Taking cues from two theoretical descriptions of the design process, the study presented here suggests that modes and models of mentorship should be added, when applicable, as a descriptive portion of the design process.
