(SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01) Alejandro Betancur, J.; Osorio-Gomez, Gilberto; Externo - Escuela - Ingeniería; Alejandro Betancur, J.; Osorio-Gomez, Gilberto; Externo - Escuela - Ingeniería; Universidad EAFIT. Departamento de Ingeniería Mecánica; Mecánica Aplicada
Currently, in the automotive industry the interaction between drivers and Augmented Reality (AR) systems is a subject of analysis, especially the identification of advantages and risks that this kind of interaction represents. Consequently, this paper attempts to put in evidence the potential applications of Head-Up (Display (HUD) and Head-Down Display (HDD) systems in automotive vehicles, showing applications and trends under study. In general, automotive advances related to AR devices suggest the partial integration of the HUD and HDD in automobiles; however, the right way to do it is still a moot point. © 2014 SPIE.

AIR-MODELLING: A tool for gesture-based solid modelling in context during early design stages in AR environments
(ELSEVIER SCIENCE BV, 2015-01-01) Arroyave-Tobon, Santiago; Osorio-Gomez, Gilberto; Cardona-McCormick, Juan F.; Arroyave-Tobon, Santiago; Osorio-Gomez, Gilberto; Cardona-McCormick, Juan F.; Universidad EAFIT. Departamento de Ciencias; Lógica y Computación
Augmented reality (AR) technologies are just being used as interface in CAD tools allowing the user to perceive 3D models over a real environment. The influence of the use of AR in the conceptualization of products whose configuration, shape and dimensions depend mainly on the context remains unexplored. We aimed to prove that modelling in AR environments allows to use the context in real-time as an information input for making the iterative design process more efficient. In order to prove that, we developed a tool called AIR-MODELLING in which the designer is able to create virtual conceptual products by hand gestures meanwhile he/she is interacting directly with the real scenario. We conducted a test for comparing designers' performance using AIR-MODELLING and a traditional CAD system. We obtained an average reduction of 44% on the modeling time in 76% of the cases. We found that modelling in AR environments using the hands as interface allows the designer to quickly and efficiently conceptualize potential solutions using the spatial restrictions of the context as an information input in real-time. Additionally, modelling in a natural scale, directly over the real scene, prevents the designer from drawing his/her attention on dimensional details and allows him/her to focus on the product itself and its relation with the environment. © 2014 Elsevier B.V.

Augmented reality application for product concepts evaluation
(ELSEVIER SCIENCE BV, 2013-01-01) Arbelaez-Estrada, Juan C.; Osorio-Gomez, Gilberto
The decision-making activities through all the design process are crucial for the final product success but currently there are limited computational tools available to provide better support to the designer especially at the earlier stages of the process. In addition the cost of fixing errors or making changes to a design escalates dramatically as the design advances in the product lifecycle. Besides, these activities, in a global design scenario, occur in different time and places, leading to a flexible and light solution that needs to be available for different users. Here is proposed an Augmented Reality (AR) application for Android mobile devices for getting feedback, via internet of a target user, in order to enhance the evaluation of aesthetical response in the conceptual design of discrete products. © 2013 The Authors.

Nowadays, it is very important to explore the qualitative characteristics of autonomous mobility systems in automobiles, especially disruptive technology like Vehicle to Vehicle (V2V) and Infrastructure to Vehicle (I2V), in order to comprehend how the next generation of automobiles will be developed. In this sense, this research covers a general review about active safety in automobiles where V2V and I2V systems have been implemented; identifying the more realistic possibilities related to V2V and I2V technology and analyzing the current applications, some systems in development process and some future conceptual proposals. Mainly, it is notorious the potential development of mixing V2V and I2V systems pointing to increase the driver's attention; therefore, a configuration between these two technologies and some augmented reality system for automobiles (Head-Up Display and Head-Down Display) is proposed. There is a huge potential of implementation for this kind of configuration once the normative and the roadmap for its development can be widely established. © 2014 SPIE.

Design of structural parts for a racing solar car
(SPRINGER-VERLAG BERLIN, 2017-01-01) Betancur, Esteban; Mejia-Gutierrez, Ricardo; Osorio-Gomez, Gilberto; Arbelaez, Alejandro; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)
The racing solar cars are characterized by the constant pursuit of energy efficiency. The tight balance between energy inputs and consumption is the main reason to seek optimization in different areas. The vehicle weight is directly related to the energy consumption via rolling resistance of the tires. The relation between weight and energy consumption is quantified. The structural optimization techniques are studied and a series of rules is obtained to iteratively improve the shape of structural parts reducing its weight. The implementation is done in a practical case and satisfactory results are achieved. © Springer International Publishing AG 2017.
Designing a concentrating photovoltaic (CPV) system in adjunct with a silicon photovoltaic panel for a solar competition car
(SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01) Arias-Rosales, Andres; Barrera-Velásquez, J.; Osorio-Gomez, Gilberto; Mejia-Gutierrez, Ricardo
Solar competition cars are a very interesting research laboratory for the development of new technologies heading to their further implementation in either commercial passenger vehicles or related applications. Besides, worldwide competitions allow the spreading of such ideas where the best and experienced teams bet on innovation and leading edge technologies, in order to develop more efficient vehicles. In these vehicles, some aspects generally make the difference such as aerodynamics, shape, weight, wheels and the main solar panels. Therefore, seeking to innovate in a competitive advantage, the first Colombian solar vehicle "Primavera", competitor at the World Solar Challenge (WSC)-2013, has implemented the usage of a Concentrating Photovoltaic (CPV) system as a complementary solar energy module to the common silicon photovoltaic panel. By harvesting sunlight with concentrating optical devices, CPVs are capable of maximizing the allowable photovoltaic area. However, the entire CPV system weight must be less harmful than the benefit of the extra electric energy generated, which in adjunct with added manufacture and design complexity, has intervened in the fact that CPVs had never been implemented in a solar car in such a scale as the one described in this work. Design considerations, the system development process and implementation are presented in this document considering both the restrictions of the context and the interaction of the CPV system with the solar car setup. The measured data evidences the advantage of using this complementary system during the competition and the potential this technology has for further developments. © 2014 SPIE.

(SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01) Alejandro Betancur, J.; Osorio-Gomez, Gilberto; Externo - Escuela - Ingeniería
In automotive industry, the dashboard has been ergonomically developed in order to keep the driver focused on the horizon while driving, but the possibility to access external electronic devices constraints the driver to turn away his face, generating dangerous situations in spite of the short periods of time. Therefore, this work explores the integration of Head-Up Displays and Head-Down Displays in automobiles, proposing configurations that give to drivers the facility to driving focused. In this way, some of the main ergonomic comments about those configurations are proposed; and also, some technical comments regarding the implemented arrangements are given. © 2014 SPIE.

INTEGRATION OF DFMA THROUGHOUT AN ACADEMIC PRODUCT DESIGN AND DEVELOPMENT PROCESS SUPPORTED BY A PLM STRATEGY
(DESIGN SOC, 2011-01-01) Osorio-Gomez, Gilberto; Ruiz-Arenas, Santiago
Quantitative Design for Manufacture and Assembly (DFMA) approaches are often applied during the last stages of the Product Design and Development Process (PDDP) as a unique activity, but it would be integrated more efficiently working from the first stages throughout the whole process according to the Concurrent Engineering philosophy. It is proposed a holistic PDDP where the activities and tools of DFMA Methodologies are integrated through its different stages in a single and distributed way, in order to obtain an integral implementation of DFMA in a ``Product Lifecycle Management -PLM'' strategy further along. This attempt is oriented to the implementation of a holistic PLM strategy in a standardized academic PDDP in the B.Eng. in Product Design Engineering at EAFIT University-Colombia. Besides, it is an initial proposal to integrate DFX methodologies in PLM, seeing that previous experiences have demonstrated that, at academic level, in projects where the application of all taught courses should be evident in the final designed products, students forget to apply considerations related to manufacturing and assembly issues.
Procedure to determine module distribution within a solar array to increase the net energy collection in a solar competition vehicle
(SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01) Suarez-Castaneda, Nicolas; Gil-Herrera, Ana; Barrera-Velásquez, J.; Osorio-Gomez, Gilberto; Mejia-Gutierrez, Ricardo
In solar vehicle competition, the available space for installation of the solar panel in the car is limited. In order to optimize space, it is difficult not to install solar modules in areas impacted by shadows, even if they cause reduction of efficiency in the overall photoelectric generation. Shadow patterns arise from the relative position of the sun to the earth, and the relative position of the vehicle towards both of them. Since vehicle, earth and sun are moving in semi-predictable patterns, computer simulations can cross and match data from such sources to forecast generation behavior. The outputs of such simulations are shadow patterns on the surface of the vehicle, indicating locations that are suitable or unsuitable to install solar cells. This paper will show the design procedure of the solar panel for a Challenger Class solar vehicle that participated in the World Solar Challenge 2013, intended to increase the net energy collection. The results obtained, illustrate how the employment of a computational tool can help in the acquisition of both qualitative and quantitative information, related to shadows position and their impact on energy collection. With data inputs such as vehicle geometry and its relative position towards the route, the tool was used to evaluate different possible configurations of solar panel module distribution and select the ones that are more convenient to the given scenario. Therefore, this analysis allows improving the solar panel design by considering important variables that were often overlooked. © 2014 SPIE.

(SPIE-INT SOC OPTICAL ENGINEERING, 2014-01-01) Betancur, J. Alejandro; Osorio-Gomez, Gilberto; Mejia, Alejandro; Rodriguez, Carlos A.
Nowadays, technologies like improved reality systems, sensing systems and communication systems, are moving forward with a high rate. This situation is very convenient for military groups that are trying to access modern technologies. According to that, it is very feasible to propose the development of electronic devices that increase the possibilities for soldiers to be alive during an armed conflict, providing them with information that can bring strategic benefits on the combat field, which is the main goal of this research. Therefore, it is proposed in this paper the early design stages of a smart army helmet, focusing in their low cost production; however, all the electronics stages specified here are proposed as prototypes. © 2014 SPIE.
Ubiquitous conceptual design of a ubiquitous application: A textile SME case study for real time manufacturing monitoring
(ELSEVIER SCI LTD, 2015-02-01) Mejia-Gutierrez, Ricardo; Osorio-Gomez, Gilberto; Rios-Zapata, David; Zuluaga-Holguin, Daniel; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)
Advances in Information and Communication Technologies (ICT), computing, networking, mechanics and electronics are changing the people's way of life. Several research efforts are leading the design and development of Artifact and Service Combination (ASC) with the implementation of Ubiquitous Technologies (UTs) in multidisciplinary sectors. However, the design process of such systems often ends in the implementation of conventional approaches and tools. A Ubiquitous Design Support Environment (UDSE) comprising an application intended to guide the different activities, tools and resources applied at the conceptual design stage is presented. After needs analysis, multidisciplinary collaborations are also required in order to generate innovative conceptual solutions, focusing this approach in the conceptual design stage of traditional design methods. Some activities from the conceptual design stage are enhanced through the use of the UDSE as well as through the use of a novel ubiquity assessment tool for concept selection and validation of Ubiquitous Products and Services. Finally, a case study on a Small and Medium Enterprise (SME) from textile sector, in a developing country, is presented to analyze and validate the presented concepts. (C) 2014 Elsevier Ltd.
