Ítem Design of an electrical power assist kit for manual wheelchair under the conditions of developing countries(Institute of Electrical and Electronics Engineers Inc., 2013-01-01) Mejia-Gutierrez, R.; Zuluaga-Holguin, D.Electric mobility has become an important issue worldwide; proof of this is that all the transportation areas are tending towards a green approach for their business by using renewable energies. In parallel form, mobility for disabled people is a global concern right now, specifically how to improve the independency and raise the standard of living of people in this situation. Electric mobility solutions have provided an important advance in the independency of patients. However, as occurs with emerging technologies the price is quite high, especially for developing countries such as Colombia. This work presents the design of an electric power kit for manual wheelchair, with the aim of making it adaptable for different wheelchair brands available in the Colombian market. © 2013 IEEE.Ítem Engineering education through an intercontinental PLM collaborative project: The Global Factory case study(Institute of Electrical and Electronics Engineers Inc., 2015-01-01) Mejia-Gutierrez, R.; Carvajal-Arango, R.; Zins, J.This article will present the experience in the development of an intercontinental collaborative project named 'Global Factory', being the first massive academic exploration of this new way of engineering work. The main goal of the project, was to collaboratively design a virtual factory to produce vehicle combustion engines, by using the Product Lifecycle Management (PLM) software CATIA V6. It was developed collaboratively by students from different universities around the world with distributed work and a centralized database. Therefore, interdisciplinary work was encouraged, leading students to collaborate with colleagues from different disciplines and countries. Students were subject to real conditions of international work and the implied working conditions (e.g. cultural aspects, time-frames, communication limitations, use of Information and Communication Technologies (ICT), etc.). Furthermore, they had to deal with the natural complexity of the technical work as well as the global interaction aspects, being a complicated task to be developed in a novel tool. Finally, the paper will describe the analysis of the project and the educational aspects that students had to face. This project sets the basis for preparing engineers of the future, who will work in a global environment. © 2014 IEEE.Ítem VIRTUAL PROTOTYPE SIMULATION CASE STUDY IN MECHATRONIC PRODUCT DEVELOPMENT BASED ON SYSTEMS ENGINEERING APPROACH(IATED-INT ASSOC TECHNOLOGY EDUCATION A& DEVELOPMENT, 2013-01-01) Mejia-Gutierrez, R.; Carvajal-Arango, R.Nowadays consumers are demanding products richer in technologies and associated services. That is why the link between disciplines, such as Engineering Design and Mechatronics, gets stronger each day, especially, due to the different functionalities and features that should be integrated in products in a more articulated manner. In order to prepare the future generation of engineers, they should be aware and must know the supporting tools recently available in the market to support and automate these interactions among disciplines. Regular engineering design approaches, start from requirements understanding and end with a physical prototype, passing by conceptual and detailed design. Nevertheless, the product design process should allow engineering students to forecast product behaviour and its validation through simulation in early design phases, before physical prototyping. In some cases, complexity increases as products require the integration of technical systems involving mechanics, electronics and control, among others. Therefore, design concepts cannot be easily tested using a traditional CAD package that needs a physical prototype for validation purposes. This article presents a case study using a Systems Engineering approach in academia (with RFLP Requirements/Functions/Logical/Physical) to develop a virtual prototype of a mechatronic product, its simulation and validation against data obtained from the real product. The RFLP method allows engineers to test designs at early design phases by using virtual prototype and virtual simulation, including behaviour and electronics. Therefore, design concepts can be validated without having the need to build physical prototypes which implies higher costs and manufacturing time. From the academic point of view, students can be aware that their design concepts will work properly in the real world by performing enriched simulation processes.
