Abstract

The Thinking Tools after Nature are a bionic approach based on simple rules in order to develop lightweight design structures without need for topology optimisation software. The Lightweight Design Thinking Tools are a further development of that approach in order to respect space limitations and more dynamic problems. Nevertheless, both tools are limited to two dimensional problems. The major aim of this research is to make the ideas of the Thinking Tools after Nature applicable in the field of mechanical engineering and product development. In order to reach this aim, the application of the method on three dimensional problems will be analysed and an approach for developing three dimensional lightweight structures using the Lightweight Design Thinking Tools will be presented.

Furthermore, in the existing approaches only very simple force application cases and bearings are considered. Since there are often more complex surfaces in the field of mechanical engineering on which forces are applied these more complex surfaces will also be discussed in the contribution.
