Análise de viabilidade técnica para o desenvolvimento de um equipamento higienizador de lâminas de barbear por separação eletrostática

Abstract

There are difficulties faced by razor users when it comes to removing hair from the blades after use. One of these problems is the accumulation of hair on the razor blades, which can result in a frustrating, less efficient, and even painful shaving experience, affecting the longevity of the blades and the quality of the shave. Therefore, many users seek solutions and techniques to deal with this issue and keep their razor blades in good condition for a longer time. The author presents an innovative hypothesis in which it is possible to remove hair from a razor by electrostatic separation. Thus, the main objective is to verify the possibility of developing the first prototype of a razor blade sanitizing device through electrostatic separation. The methodology used is based on bibliographic research related to the subject and the Six Sigma DMADV (Define, Measure, Analyze, Design, Validate) method, containing the five phases: definition, measurement, analysis, design, and validation. In the definition phase, the project scope, schedule definition, risk analysis, and the study of materials needed for the construction of the device were carried out. In the measurement phase, data collection was performed for theoretical improvement, as well as to define the critical design parameters and preparations to validate the product’s functionality. Then, in the analysis phase, an experiment using the Van de Graaff Generator demonstrated the ineffectiveness of the developed equipment, according to all proposed operating modes. Subsequently, there were comments on its details along with the visualization of the equipment in 3D software. Finally, there was a verification of the experiment, highlighting the invalidation of the hypothesis under the conditions presented in the experiment. In light of this, final considerations invalidated the theory that it is possible to separate hair from a razor blade by electrostatic separation. Therefore, it is expected that this project can serve as an example for future creations and innovations in the field when overcoming current technological limitations, providing increasing comfort and satisfaction for razor users
