Especially in mass production, every gram of weight is decisive. Through targeted optimization of the component and the use of high-quality materials, both the costs can be reduced and the service life of the components increased. An optimization always aims at least to one parameter (e.g. weight,) and tries not to influence any other objectives (e.g. stiffness). In the example the weight of the primal geometry was optimized. It could be reduced to 80% whereby the stiffness and stresses in the part have remained almost identical.
