Implementation of Design Improvement in a LCD Monitor Product Through the Application of Fuzzy Logic and Quality

Abstract

Companies worldwide aim to launch new products annually. During this process, design failures are identified. This study analyzes the implementation of a new LCD monitor, where its design negatively impacted mass production due to adhesive infiltration in the joystick actuation mechanism. The applied methodology included quality tools (PDCA, Ishikawa, Kaizen) and Fuzzy logic. As a result, the defect rate decreased from 20% to 3%, costs with spare parts and repairs were reduced, and quality and productivity indicators improved.
