EUGENGASSMANN In the German language the word “design” has a fairly narrow meaning: The product must meet the demands of the target application, so the conscious design of the look of things. In exact knowledge of the application and the user environment is vital. English, on the other hand, “design” applies to both functional construction and external appearance.

  • 04 PR Awards Ceremony If Packaging Design Award 2014
    PRESS RELEASE [4] Hannover/Munich, 28 February 2014 The winners of the iF packaging design award 2014 are honoured for their intelligent and sustainable concepts Jury recognition for intelligent and sustainable concepts: 95 entries to the iF packaging design award 2014 have been awarded the coveted iF label. The expert jury was particularly impressed with 5 entries whose consistently implemented design and focus on good usability was acknowledged with an iF gold award. iF CEO Ralph Wiegmann presented the gold award winners with the coveted trophy at the iF design awards night on 28 February 2014 at BMW Welt in Munich. The iF packaging design award is one of the three competitions in the iF design awards where manufacturers and designers from all over the world face up to the competition. Altogether, 4,615 entries from the areas of product design, communication design and packaging design were entered into the iF design awards 2014, with 1,626 entries being recognized with the coveted iF label and with a total of 75 products receiving an iF gold award 2014. The jury of the iF packaging design award 2014 observed a consistently high level of quality in this year’s entries, proving that, today, high standards are being applied globally. South Korea put in a particularly strong performance with as many as three of the five iF gold awards going to South Korean products. The experts were impressed with the wealth of original, practical and innovative packaging designs, since packaging has long become much more than just a protective skin for a product: it is a design discipline in its own right, where communication and product design are combined in intelligent ways to achieve outstanding results.

  • Linking Design Management Skills and Design Function Organization: an Empirical Study of Spanish and Italian Ceramic Tile Producers
    CASTELLÓN (SPAIN) LINKING DESIGN MANAGEMENT SKILLS AND DESIGN FUNCTION ORGANIZATION: AN EMPIRICAL STUDY OF SPANISH AND ITALIAN CERAMIC TILE PRODUCERS Ricardo Chiva (1), Joaquín Alegre (2), David Gobert (3), Rafael Lapiedra (1) (1) Universitat Jaume I, (2) Universitat de València, (3) ITC, Universitat Jaume I, ABSTRACT Design management is an increasingly important concept, research into which is very scarce. This paper deals with the fit between design management skills and design function organization, ranging from solely in-house to solely outsourced and including a mixture of the two. We carried out a survey in the Spanish and Italian ceramic tile industry, to which 177 product development managers responded. Our results revealed that companies have different degrees of design management skills depending on the approach to design function organization. Solely in-house design approach companies are the most skilled firms and solely outsourced ones are the least skilled. Despite the fact that the design function has apparently evolved towards outsourcing, this research supports the idea that, under certain conditions, the in-house design department is the best option in order to attain higher degrees of design management skills. Implications of the findings for both academics and practitioners are examined. P.BA - 79 CASTELLÓN (SPAIN) 1. INTRODUCTION In today’s competitive environment, design is becoming increasingly important. Good design, though, does not emerge by accident but as the result of a managed process (Bruce and Bessant, 2002, p. 38). Apart from the development process leading up to the creation of an artifact or product, the concept of design has traditionally involved a series of organizational activities, practices or skills that are required for this development to be achieved (Gorb and Dumas, 1987).

  • Form Follows Function Model-Driven Engineering for Clinical Trials
    Form Follows Function Model-Driven Engineering for Clinical Trials Jim Davies1, Jeremy Gibbons1, Radu Calinescu2, Charles Crichton1, Steve Harris1, and Andrew Tsui1 1 Department of Computer Science, University of Oxford Wolfson Building, Parks Road, Oxford OX1 3QD, UK http://www.cs.ox.ac.uk/firstname.lastname/ 2 Computer Science Research Group, Aston University Aston Triangle, Birmingham B4 7ET, UK http://www-users.aston.ac.uk/~calinerc/ Abstract. We argue that, for certain constrained domains, elaborate model transformation technologies|implemented from scratch in general- purpose programming languages|are unnecessary for model-driven en- gineering; instead, lightweight configuration of commercial off-the-shelf productivity tools suffices. In particular, in the CancerGrid project, we have been developing model-driven techniques for the generation of soft- ware tools to support clinical trials. A domain metamodel captures the community's best practice in trial design. A scientist authors a trial pro- tocol, modelling their trial by instantiating the metamodel; customized software artifacts to support trial execution are generated automati- cally from the scientist's model. The metamodel is expressed as an XML Schema, in such a way that it can be instantiated by completing a form to generate a conformant XML document. The same process works at a second level for trial execution: among the artifacts generated from the protocol are models of the data to be collected, and the clinician conduct- ing the trial instantiates such models in reporting observations|again by completing a form to create a conformant XML document, represent- ing the data gathered during that observation. Simple standard form management tools are all that is needed.

  • Privacy When Form Doesn't Follow Function
    Privacy When Form Doesn’t Follow Function Roger Allan Ford University of New Hampshire [email protected] Privacy When Form Doesn’t Follow Function—discussion draft—3.6.19 Privacy When Form Doesn’t Follow Function Scholars and policy makers have long recognized the key role that design plays in protecting privacy, but efforts to explain why design is important and how it affects privacy have been muddled and inconsistent. Tis article argues that this confusion arises because “design” has many different meanings, with different privacy implications, in a way that hasn’t been fully appreciated by scholars. Design exists along at least three dimensions: process versus result, plan versus creation, and form versus function. While the literature on privacy and design has recognized and grappled (sometimes implicitly) with the frst two dimensions, the third has been unappreciated. Yet this is where the most critical privacy problems arise. Design can refer both to how something looks and is experienced by a user—its form—or how it works and what it does under the surface—its function. In the physical world, though, these two conceptions of design are connected, since an object’s form is inherently limited by its function. Tat’s why a padlock is hard and chunky and made of metal: without that form, it could not accomplish its function of keeping things secure. So people have come, over the centuries, to associate form and function and to infer function from form. Software, however, decouples these two conceptions of design, since a computer can show one thing to a user while doing something else entirely.

  • Strategic Approach to Product Design and Development Process, And
    İşletme Fakültesi Dergisi, Cilt 8, Sayı 1, 2007, 43-67 STRATEGIC APPROACH TO PRODUCT DESIGN AND DEVELOPMENT PROCESS, AND EFFECTIVENESS OF INDUSTRIAL DESIGN PRACTICES Aykut Berber *, İbrahim Aksel ** ABSTRACT Emerging economies face international competition and moreover, similar technology applies to organizations in the relevant industry. Therefore companies must strive to keep their market positions or create new business opportunities. Novel and innovative strategies are required in either case, which depends on differentiation in the market. Recognized as a value for sustainable competitive advantage and commercial success, industrial design (ID) has an essential role. This paper proposes that strategic approach to product design and development process is beneficial for the effectiveness of ID practices. Context of the research in the study is divided into two sections. The first section derived from a study previously conducted in Poland and aimed to observe whether Turkish companies recognized ID as a strategic tool for differentiation. A comparison of the results was made with the results obtained in Poland. The second section of the research context focuses on Turkish companies. To explore how strategic approach to product design and development process impacts on ID practices; factors and hypotheses were generated through principal components analysis prior to regression analysis to analyze the relationship. 198 companies from textile, furniture, and home appliances industries took part in the research. Major indications of the research show that strategic effect of teamwork has a central role in effective ID practices.

  • The Principles of Inclusive Design
    Proceedings of COBEM 2005 18th International Congress of Mechanical Engineering Copyright © 2005 by ABCM November 6-11, 2005, Ouro Preto, MG THE PRINCIPLES OF INCLUSIVE DESIGN Flavia Bonilha Alvarenga Universidade Estadual de Campinas – DPM/FEM/UNICAMP – C.P.- 6122 – Cep 13083-860 Campinas - SP [email protected] Franco Giuseppe Dedini Universidade Estadual de Campinas – DPM/FEM/UNICAMP – C.P.- 6122 – Cep 13083-860 Campinas - SP [email protected] Abstract. The world population is aging and the number of people with special needs is also increasing. Nowadays, new technology and products have been developed to improve quality of life. In general, the products are designed for a specific target, the able-bodied people, excluding the rest of the population. It is known that many products are not accessible to large sections of the population. Hence, there is an urgent need for developing an inclusive methodology based on better understanding of the principles of inclusive design, which will lead to minimizing the impact of impairments and thereby extend life quality. A discussion about what constitutes good inclusive design is presented. The aim of this paper is to introduce and discuss the principles of inclusive design for implementing an inclusive methodology. Keywords: Inclusive design, Design for all, Inclusive methodology, Inclusion, Accessibility. 1. Introduction The world population is aging and the number of people with special needs is increasing. There is a need to design inclusive products to accommodate this wide range of capabilities and develop a methodology to guide the designers. The design of a product, when initiated, follows a sequence of events, in a chronological order, forming a model, which usually is common to all the designs (Back, 1983).

  • The Pedagogy of Form Versus Function for Industrial Design
    The Pedagogy of Form versus Function for Industrial Design David Domermuth, Ph.D. Abstract – Industrial Design is a combination of science and art. Determining the balance of the two is a preeminent challenge for teachers. The function is dominated by science/engineering principles while the form is an artistic/aesthetic expression. The teacher has a limited number of courses to present the foundational material while leaving enough courses to practice designing. This paper presents an objective summary of foundational courses, programs of study from various institutions, program evaluations by industrial experts, and a discussion about predetermining student success. A summary of accreditation requirements and how they affect the programs of study is also included. Keywords: Industrial Design, program of study, form versus function, accreditation, right/left brain. INTRODUCTION The concept of art is well accepted as shapes or drawings that are created to please sight or touch. Many times art is described as a pleasing design but the work of scientists and engineers is also referred to as a plan or design, such as the design of an engine or piping system. Scientists and engineers use the word design as noun to name a device or an adjective to describe the effectiveness of a system. The term design is also used to describe a number of professional fields such as Industrial, Interior, and Architectural Design. In this sense the word design blends both meanings of art and function. “Design is often viewed as a more rigorous form of art, or art with a clearly defined purpose” [Wikipedia, 1] “In the late 1910s, the two principles of “form follows function” and “ornament is a crime” were effectively adopted by the designers of the Bauhaus and applied to the production of everyday objects like chairs, bed frames, toothbrushes, tunics, and teapots.” (Wikipedia 2008) This paper concentrates on the university training of Industrial Designers/Product Designers with respect to form and function.
