In many ways, the sciences of design defy disciplinary characterization. They demand multiple epistemologies, theoretical orientations (e.g. construction, analysis or intervention) and value considerations. -

The main conclusion of the work is the practical 3D parametric design obtained for a laparoscopic surgical graspers handle that is scalable to fit each particular surgeon's hand size. In addition, it has been possible to determine that the anthropometric measure of the surgeon's hand defined as Palm Length Measured (PLM) allows the design of the 3D parametric model of the surgical handle to be conveniently scaled. The results show that both additive manufacturing and the application of ergonomics criterion provide an efficient method for the custom design and manufacture of this type of specialised tool, with potential application in other sectors. -

An Application of the Design Science Research Theoretical Framework

The research is about the need for a suitable for application design. These methods and tools were method and tools for designing virtual world applications, mostly developed for managing application design which is evidenced by many of the problems that virtual worlds continue to suffer due to poor design. The proposed activities for the classic types of applications in SE. approach uses the generative design grammar framework Therefore, their use is unsuitable for designing VW and the generative design agent model as tools for designing applications.

Furthermore, robust approach for designing these types of applications. poor design can also adversely affect the adoption and use of VWs [3], [4]. -
8 Typographic Design
8 Typographic Design Lesson overview In this lesson, you’ll learn how to do the following: • Use guides to position text in a composition. • Make a clipping mask from type. • Merge type with other layers. • Use layer styles with text. • Preview typefaces interactively to choose them for a composition. • Control type and positioning using advanced type palette features. • Warp a layer around a 3D object. This lesson will take about an hour to complete. If needed, download the Lesson08.zip file and extract it. As you work on this lesson, you’ll preserve the start files. About type Type in Photoshop consists of mathematically defined shapes that describe the letters, numbers, and symbols of a typeface. Many typefaces are available in more than one format, the most common formats being Type 1 or PostScript fonts, TrueType, and OpenType (see page 266). When you add type to an image in Photoshop, the characters are composed of pixels and have the same resolution as the image file— zooming in on characters shows jagged edges. However, Photoshop preserves the vector-based type outlines and uses them when you scale or resize type, save a PDF or EPS file, or print the image to a PostScript printer. As a result, you can produce type with crisp, resolution- independent edges, apply effects and styles to type, and transform its shape and size. 248 LESSON 8 Typographic Design Getting started In this lesson, you’ll work on the layout for the label of a bottle of olive oil. You will start from an illustration of a bottle, created in Adobe Illustrator, and then add and stylize type in Photoshop, including wrapping the text to conform to the 3D shape. -
Metrics for Measuring Sustainable Product Design Concepts
energies Article Metrics for Measuring Sustainable Product Design Concepts Ji Han 1,*, Pingfei Jiang 2 and Peter R. N. Childs 3 1 School of Engineering, University of Liverpool, Liverpool L69 3BX, UK 2 Department of Mechanical Engineering, Kingston University, London SW15 3DW, UK; [email protected] 3 Dyson School of Design Engineering, Imperial College London, London SW7 2DB, UK; [email protected] * Correspondence: [email protected] Abstract: Although products can contribute to ecosystems positively, they can cause negative envi- ronmental impacts throughout their life cycles, from obtaining raw material, production, and use, to end of life. It is reported that most negative environmental impacts are decided at early design phases, which suggests that the determination of product sustainability should be considered as early as possible, such as during the conceptual design stage, when it is still possible to modify the design concept. However, most of the existing concept evaluation methods or tools are focused on assessing the feasibility or creativity of the concepts generated, lacking the measurements of sustainability of concepts. The paper explores key factors related to sustainable design with regard to environmental impacts, and describes a set of objective measures of sustainable product design concept evaluation, namely, material, production, use, and end of life. The rationales of the four metrics are discussed, with corresponding measurements. A case study is conducted to demonstrate the use and effectiveness of the metrics for evaluating product design concepts. The paper is the first study to explore the measurement of product design sustainability focusing on the conceptual design stage. -

Eco-Designing the Use Phase of Products in Sustainable Manufacturing: the Importance of Maintenance and Communication-To-User Strategies
Eco-designing the use phase of products in sustainable manufacturing: the importance of maintenance and communication-to-user strategies Esther Sanyé-Mengual, Paula Pérez-López, Sara González-García, Raul Garcia Lozano, Gumersindo Feijoo, Maria Teresa Moreira, Xavier Gabarrell, Joan Rieradevall Address Correspondence to: Esther Sanyé Mengual, [email protected] Sostenipra (ICTA-IRTA-Inèdit) – Institute of Environmental Science and Technology (ICTA), Universitat Autònoma de Barcelona (UAB), Campus de la UAB s/n, 08193, Bellaterra (Barcelona), Spain Abstract Recently, principles in sustainable manufacturing have included the Design for the Environment (DfE) methodology with the objective of improving the environmental performance of products over their entire lifecycles. Current EU Directives on eco- design focus on the use phase of Energy-related-Products (ErPs). However, the maintenance of various household non-ERPs is performed with ErPs; therefore, the environmental impacts of product maintenance have an important role in the lifecycle of non-ErPs. This article presents two eco-design studies where the implementation of improvement strategies for the use and maintenance phase of products had relevant results. Moreover, environmental communication-to-user strategies were important to ensure the commitment of users towards eco-efficient behaviors. First, a knife was eco- 1 designed according to strategies focused on materials, processing, maintenance and communication-to-user. By applying eco-design in a cradle-to-consumer scope, improvements in environmental impact of the eco-designed product accounts for 30%. However, when accounting for eco-design of the product’s entire lifecycle, environmental impacts could be reduced by up to 40% and even up to ≈93% (depending on the cleaning procedure), due to large improvements in maintenance strategies. -
