7. A stationary part for a WPT system, the stationary part comprising:
a housing comprising:
a bottom side of the housing; and
a top side of the housing;
a primary coil; and
one or more load transfer elements,
wherein the one or more load transfer elements comprise a bottom side, a top side and a connection between the bottom side and the top side,
wherein the one or more load transfer elements are configured to transfer a mechanical load from the top side of the housing to the bottom side of the housing,
wherein each of the one or more load transfer elements is a pillar consisting of a single part,
wherein each of the one or more load transfer elements has a vertical position where a cross-section reaches a minimal value,
wherein, from the bottom side of each load transfer element to the vertical position of minimal cross-section, the cross-section continuously decreases and, from the vertical position of the minimal cross-section to the top side of each load transfer element, the cross-section continuously increases; and
wherein a bottom face of the top side of each load transfer element or a top face of the bottom side of each load transfer element comprises a cut-out configured to host at least partially one or more of a sensor and the primary coil.
