    Heuristics-based design process
    (Springer-Verlag France, 2016-11-01) Calle-Escobar, M.; Mejía-Gutiérrez, R.; Nadeau, J.-P.; Pailhes, J.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)
    This article explores the applicability of heuristic rules into the decision-making processes involved in design practices, with the aim of generating a strategic approach for the fixation, tangibilization and re-utilization of knowledge within organizations. For this purpose, the research focuses on the creation of a methodological approach and a support tool that seeks to facilitate the introduction of heuristics into particular stages of the design process, such as concept development and architecture definition. This is achieved by providing an initial analysis of the design problem, and the definition of specific problem solving actions based on heuristics. This means that, with the aid of tools specifically developed for the method, the process will help design engineers explore several solution principles with applications previously implemented in diverse domains, thus triggering creativity in problem solving activities. This will enable a more Diverse concept generation and a more detailed product development process. In addition, it will allow organizations to work with tools and procedures for them to ensure that emerging knowledge can be integrated to the proposed approach and reused in the future.

    Impact analysis of compressed hygroscopic particulate material
    (International Journals of Engineering and Sciences Publisher, 2016-01-01) Aramburo-Londoño, M.; Pérez-Cardona, S.; Calle-Escobar, M.; Velásquez-López, A.; Mejía-Gutiérrez, R.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)
    This article presents a dynamic analysis of the behaviour of a sample of hygroscopic particulate compressed material in the context of diverse scenarios of the product's lifecycle. The analysis is executed using two complementary methods: (a) an experimental study that recreates a particular impact situation in a controlled physical environment, and (b) a static virtual analysis developed under the Finite Element Method (FEM) for the evaluation of vibration effects on the product. The objective of the analysis is to determine, on one hand, the precise compressing pressure that enables the powder to maintain cohesion throughout the handling and transporting stages, and yet be easily disaggregated manually for it to be used as intended in the final stage of its lifecycle. On the other hand, it is expected of both simulations to estimate an incidence in the behaviour of the compressed powder sample derived from its geometric characteristics and its particular handling and transportation situation, with the goal of defining ideal conditions for the product packaging. © February 2016 IJENS.
