Ítem An academic design methodology for electrical mobility products - from necessity to functional prototype(2011-09-09) Osorio Gómez, Gilberto; Mejía Gutiérrez, Ricardo; Sierra Zuluaga, Luis Fernando; Universidad EAFIT. Departamento de Ingeniería de Diseño; Luis Fernando Sierra (lsierraz@eafit.edu.co); Ricardo Mejia (rmejiag@eafit.edu.co); Gilberto Osorio (gosoriog@eafit.edu.co); Ingeniería de Diseño - GRIDThe undergraduate program in Product Design Engineering at EAFIT University-Colombia, includes an applied project course during eight semesters with different topics -- Students attend their last project course in seventh and eighth semester integrated into one year topic -- In this project, they have to design a new high-tech consumer product in electrical mobility for different types of transportation need and to construct a completely functional prototype -- The objectives of these courses are to focus on the triad of “Product-User-Context” as well as to foster design, engineering, manufacturing, management and entrepreneurship skills -- In order to offer a systematic way of working, and to obtain better results, a systematic design methodology has been adopted, adapted and applied during the whole product development process in order to facilitate representation, analysis, calculation, management and control of the information related to the product -- The methodology is broadly explained through activities, tools, information and results related to four main stages: 1) Need research & problem statement, 2) Conceptual design, 3) Detailed design and 4) Prototype construction & testing -- A successful case study is presented following all the stages of the presented methodology for the development of an Electric Power-Assisted BicycleÍtem International multidisciplinary collaborative project for design of conceptual products(2011-07-06) Mejía Gutiérrez, Ricardo; Osorio Gómez, Gilberto; Sierra Zuluaga, Luis Fernando; Atkinson, Peter; Universidad EAFIT. Departamento de Ingeniería de Diseño; Peter Atkinson (arx050@coventry.ac.uk); Ricardo Mejia (rmejiag@eafit.edu.co); Gilberto Osorio (gosoriog@eafit.edu.co); Luis Fernando Sierra (lsierraz@eafit.edu.co); Ingeniería de Diseño - GRIDNowadays, due to globalization, the design and development process of complex systems demands distributed multidisciplinary work in order to improve product quality -- Within the university contextstudents are generally trained to work in groups, however, they often develop their academic projects with classmates of the same curricular program and the real industrial work situation is new for them -- To make this experience more realistic, EAFIT University in Colombia and Coventry University in the United Kingdom have joined to set-up and develop an international collaborative project course -- Two different disciplines have been paired, the engineering approach from Colombia and the industrial design competencies from the UK -- In a recent project, a real industrial need was used to reinforce the real life constraints in order to expose students to a realistic engineering and design approach -- The collaborative experience was strengthened with the co-location of all students after the UK participants travelled to Colombia for the final part of the project -- Results are analyzed in this article showing a good international cooperation scenario that enhanced the competitive level of students involved, as well as offering practical and creative solutions to local industryÍtem Propuesta de un modelo para evaluar el desarrollo de habilidades y destrezas en dibujo creativo para Ingeniería de diseño(Universidad EAFIT, 2019) Sierra Zuluaga, Luis Fernando; Ramos Betancur,Juan DiegoÍtem Prototyping industrial clay development : wax and bentonite blends characterization(Universidad EAFIT, 2020) Agredo Orozco, Andrés Felipe; Acosta Maya, Diego Andrés; Rodríguez Arroyave, Carlos Arturo; Sierra Zuluaga, Luis Fernando; Acosta Maya, Diego Andrés; Sierra Zuluaga, Luis Fernando; Rodríguez Arroyave, Carlos ArturoIn this study, rheological properties and behaviors of bentonite and paraffin wax blends used in the elaboration of a prototyping clay were investigated. For this purpose, various bentonite and paraffin formulations were prepared. 3 different material proportions were used to ensure a homogeneous phase. The rheological properties of the resulting formulations were characterized by a rotational rheometer. This paper presents the rheological characterization of paraffin wax and bentonite blends in order to obtain some insights to upscale the extrusion process of the prototyping industrial clay developed in EAFIT university.
