    Uso de ferramentas computacionais e de qualidade na melhoria de design de monitores de LCD
    (Instituto de Tecnologia e Educação Galileo da Amazônia, 2024-02-01) SILVA, Ronildo Souza da; LEITE, Jandecy Cabral
    This dissertation addresses the improvement of LCD monitor design using computational and quality tools. The research is justified by the continuous need for innovation and enhancement of these devices to meet the growing demands for quality and functionality in the global market. The study focused on solving specific design issues, such as adhesive infiltration in the joystick button mechanism, which compromised monitor operation. By applying tools such as PDCA, Ishikawa Diagram, Kaizen, and Fuzzy Logic, the research successfully identified and implemented significant improvements, resulting in a drastic reduction in defect rates and production costs.

    Companies all over the world aim to launch a considerable amount of new products every year. During this process, project failures and design problems are often detected. In this context, this study aims to scientifically explore the events that occurred during the implementation of a new LCD (Liquid Crystal Display) monitor product, where its functionality, appearance, quality, and cost are considered satisfactory; however, its design had a negative impact on the mass production process and presented a great need for improvement. The research then sought to understand the causes of the problem and apply some solutions, especially for the biggest defect found in the project: infiltration of adhesive inside the joystick button actuation mechanism. The applied methodology was developed through action research, which meant an active role in the analysis of the problem and development of solutions within the research environment and used quality tools (PDCA, Ishikawa and Kaizen) and parameters of the fuzzy logic tools (linguistic variables, fuzzyfication, Inference rules and defuzzification). As the result, the organization obtained several benefits, such as reducing the defect rate from 20% to less than 3%, reducing costs with spare parts and repair service, and increasing quality and productivity indicators. There was also an impact on product costs, with probable savings with the implementation of the improvement estimated to be around R$ 16 million in a six-month period. Considering these factors, this work produced the desired effects on its object of study in a satisfactory way.
