Application of product line commonality index (PCI) in a family of products
(TRANS TECH PUBLICATIONS LTD, 2014-01-01) Oliver Rubio, M.; Julian Mora, O.; Alvaro Guarin, G.; Pablo Carrizosa, I.; Universidad EAFIT. Departamento de Administración; Estudios en Mantenimiento (GEMI)
Currently many companies base their marketing strategy around a family of products. Thus, they regularly add new variations to products in order to meet changing market needs, or to attract new customers. Although the basic functionality remains unchanged across products, new features, aesthetic appearance and technologies are incorporated in each new product. This if it is not checked, can generate the "complexity of the product," which leads to a loss of productivity or quality. Thus, the effective management of product variations in design and manufacturing is challenging. The key is minimizing the non-value added variations through models within a range of options without limiting customers. This article discusses the factors that contribute to the "complexity of the product" and this is done through the product line commonality index (PCI) [1], which measures the level of common parts in a product family. A case study of bicycle frame displays its implementation and functionality. The index shows the possibility that the products in a family share parts effectively (modularity) and reduces the total number of parts (multifunctionality). © (2014) Trans Tech Publications, Switzerland.

Assembly planning with automated retrieval of assembly sequences from CAD model information
(EMERALD GROUP PUBLISHING LIMITED, 2012-01-01) Vigano, Roberto; Osorio Gomez, Gilberto; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)
Purpose - The purpose of this paper is to define an approach to extract the liaison graph from a 3D CAD model and analyze a method to find at least a feasible assembly sequence for the product. The method could be useful to search the optimal sequence of assembling for a product, by comparing different sequences extracted in automatic mode from a 3D CAD model. Design/methodology/ approach - The method proposed analyzes the liaison graph extracted, in order to obtain the possible assembly sequences for the product under study. The extraction of the sequences is based on some attributes and parameters of the graph. Findings - By means of the method proposed it is possible to obtain in automatic mode the liaison graph of an assembly 3D CAD model. Moreover, the study of the graph obtained allows the definition of all the assembly sequences for the product. Finally, it is possible to analyse the sequences found to select the optimal sequence. Research limitations/implications - The major limitation of the approach is, actually, the great number of impossible sequences that are extracted. For this, a little intervention by the user is required. Practical implications - The application of the method allows the manufacturer to analyze and study the optimal assembly sequence without the direct use of a CAD system. The approach could be used at the early stage of the design process and by means of the database of the PDM/PLM systems. Originality/value - The approach proposed in the paper is an original method to extract a liaison graph from a 3D CAD model. The approach to extract the assembly sequences was compared with other methods and good results have been obtained. © Emerald Group Publishing Limited.
Assembly sequences definition through hierarchical subassembly approach
(DELFT UNIV TECHNOLOGY, FAC INDUST DESIGN ENG, 2010-01-01) Gómez, G.O.; Viganò, R.
Design processes are leading to the reduction of product development time and costs. This trend applies to the evaluation of function, architecture and high level information as far as possible at early stages of product design in order to allow the designer to compare radically different solutions rather than proceeding with fine tuning of a single option. Specifically, design of assembly processes requires information regarding neighborhood, interfaces and interactions between product components from product architecture definition stage, difficult to reach at early stages of design. Besides, assembly process concerns human interaction which is considered in a subjective way when it is analyzed as a design parameter, enterprise-specific conditions, and many suppositions derived from queries of skilled staff. So, an automated tool working with general abstract information available at early stages of design could be able to present more realistic behavior against methodologies with specific hypotheses and rules. In this work an automated method to find feasible assembly sequences without human intervention, in contrast with several solutions presented by different authors, is proposed. The developed method starts with the acquisition and evaluation of topological information of interaction between components of a discrete mechanical product at the early stages of concept and embodiment design [16], followed by the identification and hierarchical classification of independent minimum level subassemblies until the completion of the assembly procedure of the system obtaining at least one feasible assembly sequence. In this way an automated tool which yields a finite discrete number of feasible assembly sequences from all possible assembly solutions, is presented. © Organizing Committee of TMCE 2010 Symposium.
Automatic assembly sequence exploration without precedence definition
(Springer-Verlag France, 2013-01-01) Viganò, R.; Osorio Gómez, G.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)
Today the assembly sequence for the products is often carried out manually and its definition, typically, is very expensive, not guaranteeing optimal solutions. Coming up with an efficient assembly sequence is the essential step to improve process productivity and reduces the time and costs related to assembly machines and equipment. The issue related to the assembly sequence of a product depends on the total number of the its components. In particular, the number of the possible sequences can be obtained through the calculus of the factorial of the number of the product components. This work presents an automatic approach intended to define assembly sequences, based on the information regard the contacts and the interferences existing among the components, which is obtained by the assembly CAD model of the product. The level of the information required by this approach allows its implementation at early stages of design, as soon as the layout of the conceptual solution of the product is defined, independently by the method used to model the CAD assembly. The procedure proposed is focused to obtain a reduced number of assembly sequences, guaranteeing that there is at least one feasible assembly sequence among them. The procedure is oriented to iteratively identify independent and important subassemblies into the CAD assembly, then merge them to specific assembling nodes and generate sequences until the whole product is analyzed. After a brief review of current methodologies developed for assembly planning, in this paper, the automated procedure for assembly sequence generation is explained and applied on an example, obtaining feasible solutions. © 2012 Springer-Verlag.
Collaborative tools for global design project management: Case study of an academic experience
(AMER SOC ENGINEERING EDUCATION, 2010-01-01) Esparragoza I.; Mejia R.; Rodriguez C.
The management of information and the capture of design ideas are very critical during the product development and product lifecycle management. They could be very challenging tasks when time, efficiency and quality are important and the concurrent design team is physically distributed in different locations. However, the existing technology for communication, the increase of tools over the Internet and the cloud computing model have made possible and accelerated the means of sharing information synchronous and asynchronously in a very effective way. This has facilitated the work of teams that in many cases are geographically dispersed around the world. Therefore, there is a need to start preparing the future engineers in the use of collaborative tools for global design project management not only to schedule and coordinate all the required tasks for the project but also to capture all the information, ideas and concepts generated during the design process which contains valuable data that supports design decisions. This paper presents the use of several tools for communication and project management used in academic collaborative global design projects. In these projects, students are required to work with international partners from different universities in coordinating activities and documenting the conceptual design for a given problem. The paper reports the experience using the tools and discusses opportunities and pitfalls in the use of them as they were identified by the authors. © American Society for Engineering Education, 2010.
Conditions for the promotion and development of creative industries within higher education institutions
(The Design Society, 2015-01-01) Hernandez, M.C.; Podesta, M.P.; Bedoya, B.E.
Higher Education Institutions (HEIs) play an important role on the promotion and development of creative industries (e.g. product design companies). These roles, however, are not clearly defined. Previous studies by the authors, conducted in Colombia, encountered several critical internal factors as well as environmental relationships proper of the ecosystem of business that affect performance in creative industries. HEIs can promote specific activities to become agents that enhance the development of these creative industries, thus contributing to overcome environmental and critical internal factors. This paper presents a model that can serve as a starting point within HEIs to establish policies towards this goal. For such purpose, the present research extended the aforementioned studies to Argentina and the United States, countries recognized worldwide for the development of "creative industries" or "creative economy". Fieldwork was performed in nine cities: two in Colombia, two in Argentina and five in the United States. Data was collected via interviews and focus group studies conducted at universities and creative industries, as well as with experts, government representatives and support organisations. A PESTEL analysis was used to identify weaknesses that could become opportunities for action within HEIs. The results allow for the establishment of nine key roles of the HEIs (i.e. education, moderator of the ecosystem, research, foster discussion, investment, on-going support, dynamism, joker, and simulation/real environment) that can be related to these institutions' substantive functions (i.e. teaching, research, extension, and support and integration), which contribute to enhance the development of creative industries, their growth and long-term sustainability. © 2015, The Design Society.

Crowdsourcing Augmented Reality Environment (CARE) for aesthetic evaluation of products in conceptual stage
(ELSEVIER SCIENCE BV, 2018-08-01) Arbeláez J.C.; Osorio-Gómez G.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)
Decision-making activities affect to a larger extent the quality, cost, time and success of a product. However, there are fewer alternatives when it comes to supporting in aesthetic evaluation during the product design stages. Therefore, is proposed a Crowdsourcing Augmented Reality Environment (CARE) that use the user's mobile devices for getting the feedback from the evaluation of products using a Semantic Differential (SD) that consider the user's context-light interaction in real time. Finally, two products were evaluated using CARE vs. the real products under different lighting and surrounding conditions. Obtaining a similar measure of products aesthetic perception between CARE and the real product, with slight variations. Additionally, an evaluation pattern among users was recognizable in the same context with slight variations using different lighting setup, that was similarly recreated with CARE. © 2018 Elsevier B.V.

(Institution of Engineering and Technology, 2018-01-01) Polanía S.; Betancur E.; Osorio-Gómez G.
In Colombia, air pollution problem is mainly caused by land transport, with a considerable number of internal combustion engine vehicles, and a motorcycles segment preference, electric vehicles emerge as an innovative solution to this problem. 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.

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.

At the end both products were tested by health-care staff members, and patent applications were issued for.
Design of pedagogic tools for teaching materials in product design engineering
(The Design Society, 2015-01-01) Patiño Santa, L.F.
The education in materials constitutes a vital part of the education of an engineer, since its comprehension determines the design and construction of products with appropriate materials that satisfy the current and future needs of the 21st century society [1]. In the Product Design Engineering degree, teaching and learning the attributes and applications of materials shouldn't be limited to lectures. This paper shows how through the design of pedagogic tools it is possible to go from a knowledge-transfer method to a student-centred method where motivation, teaching and learning strategies and problem-based learning, support meaningful learning [2] through the implementation of these tools in the classroom. © 2015, The Design Society.

Designing home decor products for umbra, within the international collaboration format as an academic experience for undergraduate students
(Institution of Engineering Designers, The Design Society, 2014-01-01) Posada, A.M.V.; Santa, L.F.P.
Product Design Engineering at Universidad EAFIT offers a special undergraduate course that allows students to have their curriculum in a flexible way. The main goal is to design home decor products for a world leading company: Umbra. This paper presents a case description of a university-industry collaboration (taking into account previews experiences with other local industries) in which outlines the course's methodology based on Umbra's design contest: to explore fresh and original designs, within the international format collaborations.umbra.com. It describes the company's briefing, the design process and the feedback from the company. One of the biggest motivations is that students have the opportunity to design for an international company and have the possibility that their products could be chosen to be produce by Umbra. Among the skills students develop are the ability to read the company's language to understand its brand identity, as well as to increase the application of design tools such as mood boards [1], emotional design [2], the use of semantic adjectives [3] and the use of the formal referent as an inspiring element. The new product must fulfil three requirements: original, practical and keep brand identity, in order to fit Umbra's brief. The most relevant aspect of the course is the professional training students receive in refining the product's form and aesthetics- to adjust the design to the consumer preferences- and how the methodology course enhances student skills, such as creativity and sensibility, in order to get prepare for their out coming mandatory industrial semester.
Designing with light and meaning: A design project for luminaries inspired by “The Little Prince by Antoine de Saint Exuspery”
(Institution of Engineering Designers, The Design Society, 2019-01-01) Patiño Santa L.F.
Teaching to design is a challenge in this era. 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.

Development of a model for evaluating the NPD process in SMEs: A Latin American experience
(Elsevier, 2014-01-01) Hernandez, M.C.; Montoya, M.V.; Martínez, J.F.
This article presents the findings resulting from a research project carried out in Medellin, Colombia, that was aimed at developing a model of diagnosis for the NPD process in manufacturing SMEs, adapted to the Latin American context. Four aspects were considered to develop the model: (i) Rational logic for problem solving based on the paradigm that a problem can be solved through systematic application of general principles and standardized knowledge, (ii) The Grounded Theory research approach, (iii) Integration of learning processes based on reflective and, (iv) Kolb's learning cycle as basic premises for the generation of a prescriptive model considering that the diagnosis process involves a learning process. Results obtained from the four companies selected for the study helped to validate an initial version. The model has proven to have great potential to improve the NPD process, as well as an opportunity to develop future comparative studies. Findings in the discussion and further reflection generated by the application of the four tools that encompasses the model within the companies, proved to be appropriated as a reflective practice and also a continuing learning process for SMEs. © 2014 Published by Elsevier B.V.

Development of a technology-based design environment focused on improving user experience
(Elsevier, 2014-01-01) Ríos-Zapata, D.; Osorio-Gómez, G.; Mejá-Gutiérrez, R.
Computer tools usage has became one of the major trends in humanity and product design processes are not stranger to this situation. That is the reason why different computer tools (hardware and software) have been developed in order to support design tasks, enabling design processes to achieve more innovative solutions by offering more time to creativity. Nevertheless, the quantity and variety of available tools bring a high level of complexity and their articulation becomes an important need to be tackled, aiming to integrate hardware and software applications onto a single platform. This article describes the development of a collaborative design environment supported by the usage of computer tools for product design processes. The proposed model is based on the integration of different commercial hardware into a single platform. It is meant to support product design meetings of collocated design teams in a work station where all team members can interact with design concepts in a synchronous way. After the construction of a first functional solution, a redesign process was conducted to develop a platform where key aspects such as functionality, aesthetics and ergonomics were considered. Finally, the proposed solution is not only intended to perform as a stand-alone platform, but also as a networked workstation that will allow distributed design processes. © 2014 Published by Elsevier B.V.
