The lever of breast milk pump had to be improved and the weakness in the middle removed.

After a trough analysis of the problem was it decided to change the material and strengthen the structure on the most vulnerable place.

The kink in the middle of the lever turned out to be a vulnearability.

Niederberger-Engineering AG created FEM-analyses, to optimizes the pump lever.
