Aplicação do projeto conceitual para o desenvolvimento de um sistema de aquecimento solar

Abstract

Innovation can be considered as a substantial change or creation in a product in order to bring benefits to society. Solar energy is abundantly found in Brazilian territory. The market for solar heating systems in Brazil is constantly growing, with great market potential. The most common heating systems of the market present collector and reservoir as main components, being manufactured with diverse materials. The development of a new product can be defined as the union of three phases: pre-development, development and post-development. These three steps comprise the design of a flat plate solar heating system with reservoir, with the proposal to maintain the functionality of one using lower cost materials than conventional ones. This work presents the application of a reference model in product development projects for a domestic solar heating system using the Rozenfeld Reference Model. In order to carry out this work, we specifically chose the conceptual design stage, present in the model development phase and used tools such as Function Structure Representation, Systematic Analogy, Modular Indicator Matrix and Morphological Matrix. The results of the application of the techniques indicated for this stage of the Model were achieved, as they allowed the analysis and the better decision making regarding its aspects of functionality. When performing some functional tests on the specified raw material, failures occurred that required the change of strategies for the next step of the model (detailed design). The application of the model was efficient, since it allowed the early identification of the limitations when specifying the raw material, avoiding possible damages caused by the continuation of the product development process.
