Given the real need for advances in studies such as the relationship of soil-machine dynamics, it is clear that there are almost no innovative systems developed to attend this demand. The design of agricultural machinery and equipment can be facilitated by having information and mechanisms that allow the prediction of the mechanized-set behavior in real work situation, especially regarding the traction effort demanded by the tractor, due to the energy demand of the equipment that interact directly with the soil. Obtaining this information usually requires high-cost imported laboratory equipment. Thus, the objective of this work was to obtain the design specifications for the development of a direct shear and soil pre-compaction analysis equipment with low manufacturing cost. The Phases Methodology was used to obtain the necessary parameters, in the informational phase of the desirable aspects for each design requirement. Through a step-by-step analysis, it was possible to obtain customers’ needs, together with the establishment of the desired criteria, and the design requirements for the new product development was generated. The use of the Phases Model allowed the transformation of customers’ requirements into the design requirements, enabling hierarchization by degree of importance and thus enabling the execution of future steps.
RESUMOO objetivo desse trabalho é desenvolver um aplicativo pedagógico como tecnologia de informação e comunicação móvel com acesso à Internet, a fim de auxiliar a disciplina de Desenho Técnico nas escolas da rede pública. O projeto foi executado pelas alunas da especialização em Ciências e Tecnologias na Educação do Instituto Federal Sul-rio-grandense, nos meses de junho e julho de 2016, como parte da disciplina de Informática para Educadores.Para desenvolver o aplicativo, utilizou-se um site gratuito, denominado Appy pie, o qual apresenta uma interface intuitiva para criar novos apps em plataformas como IOS, Android e Windows Mobile. O aplicativo gerado visou tornar-se uma ferramenta de complementariedade do ensino de Desenho Técnico, sendo um facilitador na pesquisa de diferentes tópicos, porém não são todos que se adaptam à nova tecnologia, devido à dicotomia das escolas, gerando um entrave educacional para a realização de testes do aplicativo. Contudo, o software teve boa aceitação pelo corpo docente da Instituição Federal Sul-rio-grandense, podendo ser, futuramente, inserido na grade da disciplina, como assessório de consulta, visto que estimula a pró-atividade do educando em tarefas extra classe.
