According to the constraints of the DPs, CAD drawing was implemented as shown in Figure 16 and Table 10. To meet the design guide, the position of the boundary between PP and TPV and the shape of the lip were adjusted to decrease the lip angle and increase the overlap distance to 5.6 mm. Because the surface of flocking and the TPV material were changed, CAE analysis for the contact load and vibration of VDA 230-206 was performed to change the thickness of the lip and notch shape where the lip and carrier were connected. As a result of CAE, it was predicted that the maximum acceleration was reduced from 0.38 to 0.1g as shown in Figure 17
