The present article is focused on the multiple practical application of the Poka - Yoke method on a selected workstation in an industrial enterprise, which operates in the mechanical industry and which is among the world's leading manufacturers of seat skeletons for the automotive industry. In the article, a step by step progressive rationalization of the semi - automatic workplace is captured which is used for easy application of a rubber seal on a mechanism for regulation of car seat movement in the forward and backward plane. Despite the relative simplicity of the whole operation, a significant number of failures occurred at the beginning of production caused by human factor. For this reason, the authors of the article suggested several proposals based on observing and analyzing the causes of failures, in accordance with the Poka - Yoke method. The proposals are as follows: Laser sensor, which confirms presence of the rubber seal in the groove, a pressure sensor, which controls the correct position of holders, slots to check the correct length of the manufactured product, a pneumatic actuator, for blocking the removal of the product from a nest in case of failure, an intelligent printer, that only prints the barcode after the completion of the entire operation, next the so called double button for protection of operator health and finally the warning label for visual control of finished product by operator. The reasons for rationalizations, their benefits and costs together with detailed photographic documentation form the content of the article.
