Abstract
Avanzando cada vez más rápido en un mundo industrializado y tecnológico, la ciencia y la ingeniería evolucionan para adaptarse cada vez más a las necesidades de las personas, materializándose en productos y servicios que escalan a nivel global en la interconectada sociedad moderna.Buscando la constante innovación, las soluciones ya no tienen un carácter netamente funcional, si no también estético y de identidad con su usuario, los cuales se ven reflejados en sus pertenencias dando a conocer su personalidad y pensamientos, siendo esto determinado por las características físicas de los productos.En la presente memoria se desarrolla una herramienta de soporte CAD generadora de partes frontales de automóviles, en el contexto del diseño automotriz exterior, ya que son percibidas como expresiones humanas y animales, vale decir: “las caras de los autos”. Comprendiéndose como parte frontal el estudio de: ambos focos y las entradas de aire adicionales.Esta herramienta tiene base en el diseño paramétrico, a través de la transición de conceptos opuestos, buscando la identificación final del usuario con su vehículo.Como herramientas de trabajo se utilizaron el software Rhinoceros 3D y su plugin Grasshopper, generando modelos para luego ser implementados a modo de prueba en el automóvil eléctrico Twizy, que forma parte de la investigación sobre robótica y vehículos autónomos, realizada por el centro de investigación: AC3E.La memoria está enmarcada en el proyecto Fondecyt N° 1130674, el cual busca generar el conocimiento necesario para desarrollar nuevas herramientas CAD para asistir a diseñadores e ingenieros en el desarrollo de productos, específicamente en la etapa de desarrollo formal.En el desarrollo de formas entra el concepto de diseño generativo, en el cual el diseñador/ingeniero pasa de diseñar el producto directamente a diseñar el “proceso de diseño”, trabajando conjuntamente con el computador, incorporando e ingresando objetivos de diseño en el software generativo, junto con parámetros como materiales, métodos de fabricación y limitaciones de costos, lo cual es utilizado por los algoritmos del programa que entregan todas las permutaciones posibles de la solución, dando lugar rápidamente a alternativas de diseño, siendo el profesional quien elige cual se adapta mas a sus necesidades. En el caso del proyecto Fondecyt N° 1130674, en la herramienta se ingresan parámetros y variables geométricas que trabajan en conjunto con el desarrollo verbal de conceptos.
Moving faster and faster in an industrialized and technological world, the science and the engineering evolve to adapt increasingly to people’s needs, materializing in products and services that scale in a global way in the interconnected modern society.Looking for constant innovation, solutions no longer have a purely functional character, but also, aesthetic and identity with their users, which are reflected in their belongings revealing their personality and thoughts, this being determined by the physical characteristics of the products.In the current thesis, a CAD support tool is developed which generates car's fronts, in the context of external automotive design, since they are perceived as human and animal expressions: “The car’s faces”.Understanding the front parts studied as: the headlights and the additional air intake slots.This tool is based in parametric design, through the transition between opposite concepts, seeking the user identification with the vehicle.The working tools were: Rhinoceros 3D software and Grasshopper plug-in, generating models to be implemented, in the Renault’s electric car: Twizy as a test, which is part of the research on robotics and autonomous vehicles, carried out by the research center: AC3E.The report is framed in the Fondecyt project No. 1130674, which seeks to create the necessary knowledge to develop a new CAD tool to assist designers and engineers in product development, specifically in the formal development stage.In formal development, enters the concept of generative design, where the designer/engineer moves from designing directly the product to designing the "design process", working in conjunction with the computer incorporating and entering design goals into generative software along with parameters such as materials, manufacturing methods and cost constraints, which is used by the program’s algorithms that give all possible permutations of the solution, quickly giving rise to design alternatives, being the professional who chooses which adapts more to their needs. In the case of the Project Fondecyt N° 1130674, the tool is entered parameters and geometric variables that works together with the conceptual word development.
