Projeto conceitual em CAD de um carrinho para transporte de cilindros de oxigênio

Abstract

The construction of an engineering project, from ideas, conception, solution, purchase of materials, and even the manufacturing processes of the final product provide a large number of possibilities that determine costs and their viability. Therefore, an analysis of products on the existing market for the transport of oxygen cylinders with manual traction was essential for identifying a product that came close to the functions wanted and in identifying a reference model for comparison and reengineering. The use of tools, such as MESCRAI, enabled alternative solutions and the generation of new ideas prior to the conception of the new conceptual proposals, which were modeled three-dimensionally in CAD (Computer-aided design). Another decision-making tool, the Pugh method, made it possible to identify item by item in a comparative way and helped evaluate it as better, worse or equal, enabling a final comparative score. In addition to the theoretical design process, with the help of CAD, it is possible to visualize and materialize ideas in the creative and collaborative process with its functions. Furthermore, it is possible to suggest changes in a possible physical construction process aimed at manufacturing. In this work, the final product met the modeling and modification objectives proposed within reengineering and also the processes followed.
