Fig. 8
Analysis of the point of application (PoA) and its effect on anchoring stiffness and pressure distribution. (a) Section view illustrating the parameters that define the PoA. (b) Conceptual diagram showing how the moment induced in the anchoring structure changes with the PoA when actuator forces are applied. A PoA that is too small leads to concentrated pressure on specific areas, causing discomfort, while an excessively large PoA reduces contact pressure and frictional force, resulting in the anchoring system being pulled upward. Note that this figure is intended as a conceptual illustration of the expected parameter relationships, not as an exact plot derived from the analytical model.
