Ergonomic Function In Furniture Optimisation

Chairs are items of furniture that are in direct contact with the human body – sometimes even for many hours a day. This is why the ergonomic aspect is one of the most important factors in the design process of this piece of furniture. Moreover, it is to a greater or lesser degree connected with other features of the final product, such as: aesthetics, strength and rigidity, stability as well as the cost of materials and production. By reaching a good enough compromise between these features a numerical optimisation of a chair can be arrived at. In this paper mathematical descriptions of the above features are proposed with the aim of preparing an optimisation model of a chair. The decision variable box was formed by a set of selected furniture dimensions and the limiting conditions were to be realised indirectly by minimisation or maximisation of a goal function. The analysis of selected features as well as the expected result of the calculation leads to the conclusion that in order to achieve the best chair project from an ergonomic point of view, a polyoptimisation is required in which many features are considered simultaneously.
