Application of the Equid Methodology and the Principles of Macro Ergonomics in Seat Design

Abstract

It is known that the main concept of Ergonomics consists in the understanding of the adaptation of the jobs and the needs of its users. When it comes to seating we should also consider several topics, this adaptation is of fundamental importance for the perception of comfort of users in relation to their jobs. A Brazilian company located in the south of the country developed a study whose main theme contemplated the application of tools linked to ergonomics through concepts that aimed to design a seat that would meet the functional needs of its users, as well as to understand market action and commercial viability, and also of their interaction in corporate environments. Therefore, this paper aims to demonstrate the application of macro ergonomics concepts and the Equid/2008 tool in the design and production of seat and, as specific objectives, the demonstration of commercial needs and the respective users with the multidisciplinary team involved as well as evidencing the final result of the product and its respective relevance in the national and international market. Methodologically semi-qualitative questionnaires based on the precepts of the tool and macro ergonomics concepts were applied in all stages of the process, involving development team, process and manufacturing, commercialization and users. It was concluded that the Equid tool and Macro Ergonomics concepts have proven effective in the design and definition of the ergonomic and functional characteristics of the product. Besides that, they are fundamental to list the functional needs of the product and the team of workers involved in its manufacture.
