Avaliação da viabilidade da redução do número de parafusos de fixação no suporte do tanque em lavadoras de roupas

Abstract

In a business context where it is always desirable to maximize profits, the reduction of products’ manufacture cost appears as a strategic alternative, whether through optimization of oversized parts or the removal of fastening components, such as screws. The main challenge to achieve this, however, is maintaining the quality and functionality of what is being produced and sold. This scenario is currently evident for those who work in the home appliance industry in Brazil, with consumers demanding better and more affordable home appliances. In this context, this document proposes to analyze the technical feasibility of reducing the number of screws that fix the tub on the tub support of washing machines, considering the need to guarantee their quality and safety in use. This study was carried out through the development of practical experiments, product-level tests to evaluate the performance of the proposed model, and comparative tests to visualize, through statistical analysis of the results and research of pre-existing knowledge, if there has been a loss of quality. The studies have shown that the reduction is promising, contributing to cost reduction without impacting the functionality of the washing set.
