Ítem Formulation and Simulation of a Hybrid Solar PV-Wind Generation System with Photovoltaic Concentration for Non-Interconnected Areas to the Energy Grid(EDP Sciences, 2020-07-24) Torres, José luis; Tamayo, Jortge Mario; Bernal, Santiago; Sierra, Julián; Nieto, Cesar; Mejá-Gutiérrez, R.; Gómez, G.O.Different isolated systems with conventional generation sources are installed in Non-Interconnected Areas (ZNI) in Colombia while off-grid renewable systems are a trending answer for the energy supply in these regions.Ítem TEACHING TECHNICAL DESIGN SPECIFICATIONS IN PRODUCT REDESIGN PROCESSES USING THE FBS MODEL(American Society of Mechanical Engineers (ASME), 2020-01-01) Montoya, Ivan D.; Rendon-Velez, Elizabeth; Gallego-Sanchez, Juan A.Establishment of technical design specifications for the redesign of technical systems, which are not derived from customers needs, relies heavily on designers intuition and experience. The very few methods proposed in the literature for the establishment of such technical design specifications hinders the learning process in conceptual design subjects. The objective of this article is to propose a structured method for identification of technical design specifications based on the function-behaviorstate (FBS) model applied on redesign tasks. The method is being taught to students on the course of methodical' design in order to develop their abilities on the identification of technical specifications without relying on previous knowledge on the system and relying more on detailed observation. This method is based on the observation and identification of the different states taken by the attributes of the entities conforming the system (i.e., flows-function carriers-environment). A small scale preliminary study was conducted in order to validate the initial performance of the proposed method. Eight groups made up of undergraduate mechanical engineering students with basic knowledge in conceptual design were instructed to identify technical design specifications. The redesign task was to create an automated solution for replacing the manual production process at small food manufacturing companies. Four groups of students had to establish the specifications using their experience while the other four groups had to use the proposed method. Initial results showed for the proposed method a 36% increase in the number of identified specifications.Ítem Dice preconceptions exploration card: A tool to avoid preconceptions among students in multidisciplinary entrepreneurship courses(Academic Conferences and Publishing International Limited, 2019-01-01) Molina V.; Maya J.Many difficulties could be saved if a team starts a project using a tool to promote a clear understanding of the terms they are going to use and the abilities of each member. Design, creativity, innovation, and entrepreneurship, have been studied from many different disciplines, sometimes giving diverse definitions and setting false expectations on what everyone does. The problem becomes larger when we take into consideration that interdisciplinary collaboration and integration on these fields is always promoted. So, when working with multidisciplinary groups, some participants use the terms indistinctively when discussing their new projects, particularly in the entrepreneurship class, bringing those incompatible, sometimes mistaken, views to the teamwork, making it necessary to discuss about their preconceptions. The aim of this paper is to propose a preconceptions exploration card as a pedagogical tool for entrepreneurship education in multidisciplinary groups that allows students to have that first discussion in which they can understand each other's discipline and strengths. To propose the card, we did a content analysis of expert literature to extract the most common words used to define each field and that way incorporate it to the tool. The tool consists of one first card, the preconceptions explorations card, to randomly be filled by one student on the definition, objectives, core concepts, the actors, and the context of one of the disciplines; the second, reference card, allows to compare the answers of the first card against what is defined in the literature on those disciplines. The paper contributes to relevant debates in education around the placing of value in multidisciplinary teaching, finding solutions for ill-defined societal challenges requires the integration of different knowledge fields. This century's main problems, such as water, poverty, environmental crises, violence, terrorism and destruction of social fabric can't be adequately tackled from the sphere of specific individualist disciplines. This poses a problem, since education systems are mostly monodisciplinary, resulting in experts in rather narrow fields. Although it is frequently attempted, the situation cannot be solved by creating teams of specialists in different areas around a given problem. This team approach only leads to an accumulation of visions emerging from the participating disciplines. © Proceedings of the 14th European Conference on Innovation and Entrepreneurship, ECIE 2019.

Motivating the students to learn a systematic design process, designing exercises for them to develop basic competences as Product Design Engineers (PDE) besides that, to include the teaching of values and integrity constitute big challenges in a first year study. This paper exemplifies the union of these two thoughts: how to teach design motivating the student to learn and how to reflect about the human values of the classroom. A pedagogic strategy is formulated and developed in a basic course. Design a standing luminaire inspired by the work of universal character like the Little Prince by Antoine de Saint Exuspery. This ongoing project shows how the students are guided to understand their discipline in a design process integrating thought, feeling and doing with an ethics reflection designing with light and meaning. © 2019 Institution of Engineering Designers, The Design Society.

The design is proposed according to the context of remote areas, which are off-grid or where utility grid’s quality is low, and considering the possibility of having standalone charging stations installed in such places. The proposed system integrates several hardware components and communication protocols by making use of Internet of Things (IoT) and Cloud Platform technology. The presented solution is a low-cost infrastructure and enables real-time monitoring and data storing for future analysis. © 2019, Springer Nature Switzerland AG.Ítem Design and implementation of an academic project for fostering open innovation between companies from different industrial sectors: A case study(Institution of Engineering Designers, The Design Society, 2019-01-01) Gutierrez-Aristizabal J.; Ruiz-Arenas S.Collaborative projects integrating companies and universities have been traditionally conducted between entities from interrelated industrial sectors. Nevertheless, theory about innovation states that the involvement of people from different disciplines, expertise, and type of business foster new perspectives and enables a robust body of knowledge that will derive innovative results. This article aims to share the experience obtained through the planning, and execution of the so-called project “First View Design Lab 2018” (FV). FV is an annual collaborative and academic project organised by Universidad EAFIT that integrates the industry and the academy, in order to find new opportunities of products and services. This project implements design methodologies, co-creation and open innovation to enable knowledge transfer, and to get innovative concepts of new products/services. In 2018, FV was focused on exploring how heterogeneous teams composed by companies from different industrial sectors and the academy contribute to get new concepts that explore other business cores, different from the ones of the companies involved. The process followed enabled overcoming important challenges, such as the reluctance of Colombian companies for working in collaborative projects with other companies and the academy. © 2019 Institution of Engineering Designers, The Design Society.

In educational practice, mood boards help and improve an engineer's visual thinking. Currently there appears to be a very limited understanding by students on how to incorporate in their design, product features from visual theme boards; and students complain of the lack of precise instructions by teachers, making it difficult to conduct the design process. Being inspired by a perfume bottle for example helps create a systematic approach to mood boards by defining a visual framework to determine the styling outcomes. The findings suggested that the use of an inspiring element facilitates visual and aesthetic connections, resulting in a significantly more motivating process for students, as well as an encouraging guiding process for teachers that seek to achieve design accuracy. © 2019 IEEE.Ítem The Aware User Experience Model, Its Method of Construction and Derived Heuristics(SPRINGER, 2020-01-01) Maya J.; Ariza N.Psychological experience possesses many different determinants of affective, cognitive, and behavioral order in complex interaction and mostly hidden to our consciousness. User experience models face this complexity by presenting a reduced set of variables and interactions. Most of these models have been created on a deductive but also largely intuitive basis. This poses three problems: First, the UX models’ authors don’t propose a systematic response to the question of “how to know what variables use into the UX model?” Second, most UX models overlook the components that arise to the user’s consciousness. Third, even with this multitude of UX models, UX designers continue to rely heavily on intuition. Based on previous work, we propose the Aware UX Model, built systematically, and gathering empirical users’ data. It focuses on the components, mostly thoughts, and feelings, that arise in the user’s consciousness. The model provides their characterization and a rational account of its emergence in the UX. In addition, we propose a construction method for UX models based on our own process. We expose a case study to substantiate the Aware UX model and to contribute to its validation. Finally, we propose heuristics coupled to the Aware UX model components. © 2020, Springer Nature Switzerland AG.Ítem Novel smart dental composite with rechargeable antimicrobial capability(Society for Biomaterials, 2019-01-01) Londoño J.J.; Kosater W.; Correa S.; Orrego S.Statement of Purpose: The most common cause of failure for dental restorations is secondary caries [1]. It results from bacterial colonization (e.g. Streptococcus mutans) at the interface between the implanted biomaterial and hard tissue. The bonding strength is degraded by bacterial acid production and cyclic stresses from mastication. Resin composites are currently the most widely used material for restorations due to their great aesthetics, strength, and ease of processing. However, resins present the highest failure rate [2] due to the increased accumulation of biofilms (increased acid production) compared to other restorative materials [3]. Recent studies have developed resin composites with antibacterial properties to mitigate acid production. However, the antimicrobial effects are vanished over time since the antibiofilm agents leach-out and no longer are capable to repel bacteria. In this work, we present a novel smart biomaterial with long-lasting antibiofilm capabilities with a single filler. The novel resin filler produces electrical charges that disrupt oral bacteria, (antimicrobial effect) and are activated by mastication. © 2019 Omnipress - All rights reserved.Ítem Analysis of relevant variables to monitor a photovoltaic charging station through the Function to Data Matrix (FDM) method(Institution of Engineering and Technology, 2018-01-01) Cárdenas-Gómez I.; Fernández-Montoya M.; Mejía-Gutiérrez R.The growth of the electric vehicle industry has brought the development of charging stations and the need for good performance of such systems. The large amount of information that can be monitored in these systems can represent a problem for a good operation in terms of control, computational cost and time. For this reason, it is necessary to make a selection of variables that allows to decrease the data-set’s size without compromising the quality of information, needed for a proper information management system. There are several methods for prioritizing variables, such as the Function to Data Matrix (FDM). This method takes into account the functional analysis of the system, as well as the operative states and their relationship with the basic functions and variables. This enables to obtain a Variable Relevance Indicator (VRI) to define which variables have a higher importance under a particular perspective based on the main function of a system. This article presents the process of analyzing a photovoltaic charging station through the FDM method in order to define the most relevant information to be deployed in a future remote monitoring system. © 2018 Institution of Engineering and Technology.

Mechatronics has been a reference for synergetic integration of technology. However, synergy is obtained not only from technical issues, but through professional skills. Nevertheless, traditional education and industry standards focus only on the technical side. The study case is performed within the program Integrated Design of Technical Systems by implementing strategies such as integrated scheduling, integrated assessment and project proposal with application fields such as agriculture, robotics, health and mobility. This approach does not require additional credits for a project course, since the project lies underneath the courses. It has led to an increase of enrollment of students, which is significant during times when less engineers opt for further technical education. © 2018 IEEE.Ítem Towards measuring aesthetics in the classroom: A cross-cultural translation and adaptation of an aesthetic pleasure scale in design(Institution of Engineering Designers, The Design Society, 2018-01-01) Garrido-Possauner L.M.; Maya J.Measuring complex constructs has always been a big challenge for researchers and educators; aesthetic pleasure is not the exception. Many scales have been proposed but with limited validity and reliability; however, the aesthetic pleasure scale from the Unified Model of Aesthetics (UMA) lacks these shortcomings. Given that our research is in a Spanish speaking country, we needed the scale to be in the local language so that it could be understood when implemented with local respondents. Most translation methods rely on the translator’s expertise but, based on social cognitive methods, our approach aims to be not only constructed for but also from the target respondents’ language. The aim of this paper is to illustrate the process that is being taken in order to gain understanding of the respondent’s vocabulary. © 2018 Institution of Engineering Designers The Design Society.

However, the country is not ready to adopt this technology on a large scale. In this way, this document proposes the development of the Quality Function Deployment (QFD) methodology in order to define and categorize Engineering Characteristics (EC) of an electric hybridization kit for motorcycles in the Colombian context. The proposed kit is oriented to the Street\sport segment, with an engine displacement between 111 c.c and 135 c.c. Besides, a technical and competitive analysis of the kit, with direct competitors in the Colombian context, based on the requirements provided by a multidisciplinary group of engineers and potential users is presented. Finally, the results obtained from the methodology implementation are classified according to the PDS categories proposed by Pugh for a further stage of product design. © 2018 Institution of Engineering and Technology.

Several scales have been used but with restricted validity and reliability; notwithstanding, the APID (Aesthetic Pleasure In Design) scale developed in English, as part of the UMA (Unified Model of Aesthetics) project, lacks these limitations. Our research, being in a Spanish speaking country, required the scale to be in Spanish to be comprised and applied to domestic respondents. The adaptation of psychometric instruments with conceptual and linguistic challenging constructs, often is difficult, as the items used to assess the construct do not always have a direct translation. Also, it is possible for the adapted version to require different items that were not considered in the original instrument in order to preserve the content’s equivalence according to the target culture. A qualitative-quantitative mixed approach is proposed in order to overcome these issues. The resulting instrument has been statistically tested, proving to be both valid and reliable for the measurement of aesthetic pleasure in design. The final scale consists of five items: bonito, hermoso, agradable, llamativo and me gusta. This paper aims to improve the understanding of how aesthetic pleasure is perceived and therefore expressed by the local respondents gaining insight into how this construct is mentally represented and categorized by the respondents. It also aims to illustrate how psychometric scales based on respondents’ vocabulary have a great potential as usability assessment instruments. © 2019, Springer Nature Switzerland AG.Ítem How should an entrepreneurship ecosystem be? Entrepreneurship ecosystems as an artifact of design(Academic Conferences and Publishing International Limited, 2017-01-01) Molina V.; Maya J.entrepreneurship ecosystems are the new trending topic in entrepreneurship research: We are trying to characterize them, measure them and even replicate them. However not many things are certain about them. Are these ecosystems just a collection of parts? If every entrepreneurship domain is present in a region, do we have an ecosystem? Until now entrepreneurship ecosystems, have been widely studied from a managerial and economic standpoint. There are some methods for measuring growth, startup creation and other economic results, but entrepreneurship ecosystems are more than numbers; cultural, social and human aspects in general have been underestimated. With this proposition of entrepreneurship ecosystems as design artifacts what the researchers are trying to portray is that fostering entrepreneurship ecosystems requires a human intervention, and a design approach may help to understand why some ecosystems flourish and some other perish. The main invitation of this paper is to leave preconceptions and usual managerial approaches to embrace the view from systemic design and understand entrepreneurship ecosystems as a complex system that is designed to promote the interactions of agents, the fascinating part of it, is that all of those new interactions, change the ecosystem and redesign it every time. Presenting the entrepreneurship ecosystems with a view from design can help us fill the gap between theory and practice when we try to foster an entrepreneurial ecosystem in a region. Adding the design approach could help policy makers and stakeholders of entrepreneurial ecosystems around the world to formulate better methods and practices to describe, model, propose and reconfigure the ecosystem. © 2018 Academic Conferences and Publishing International Limited.

Due to variations in environmental and load conditions, battery cells and their instrumentation devices can experience deviations from their standard operation values, leading to an imprecise measurement of State Of Charge (SOC) indicator variables. Then, SOC estimation models are required. These estimations developed through analytical models consider intrinsic battery chemistry variables and operation cycle conditions are taken from charge and discharge testing; where hysteresis phenomena, measurement, and theoretical adjustment errors can be identified over Open Circuit Voltage (OCV)-SOC curves. This study compares the model adjustment errors of several estimation methods, taken from literature to approximate the OCV-SOC curves of a rechargeable battery pack. © 2019, Springer Nature Switzerland AG.
