Proposta de ferramenta para a criação de poka yokes de produto durante o processo de desenvolvimento

Abstract

Poka Yokes are mechanisms that prevent errors in the handling of the product by the user and prevent component assembly errors during its manufacturing process. However, there is a system for allocation of these mechanisms, and the existing literature rarely addresses this issue. The proposed tool in the article offers a method for allocating poka yokes during the PDP (in the conceptual design stage) in order to improve decision making when allocating poka yoke product. The tool offers potential gain of time for developing, for the allocation mechanism is held at the design stage of ideas. Often the poka yoke device is allocated when the product is in life series or validation testing. Descriptive implementation of the proposed tool occurs from the reverse analysis of two existing products. Preliminary results indicate that the proposed method is valid. In both cases proposed for validation (stylus and outlet), the expected result was achieved and validated. When applying the stylus, a new position was created, aiming to increase security while using the product. In making it was implemented an insulating material, preventing electrical shock to the user.
