Apparatus for moving a pair of opposing surfaces in response to an electrical activation
First Claim
1. A method for optimizing hinge geometry comprising the steps of:
- conducting finite element stress analysis on a three dimensional model of hinge geometry for a support structure operably engagable with a piezoelectric actuator to predict performance;
analyzing separate curves for force versus displacement for the support and the piezoelectric actuator; and
identifying an intersection of the separate force versus displacement curves to optimize hinge geometry.

Abstract
An apparatus for moving a pair of opposing surfaces in response to an electrical activation having a support including a rigid non-flexing portion, at least one pivotable arm portion extending from the rigid non-flexing portion, a pair of opposing surfaces with one opposing surface on the at least one pivotable arm portion for movement relative to one another, and a force transfer member operably positioned for driving the at least one pivotable arm portion in rotational movement. An actuator is operably engaged between the rigid portion and the force transfer member to drive the force transfer member in movement relative to the rigid portion to pivot the at least one pivotable arm portion with a loss of motion of less than 40% in response to an electrical activation of the actuator.
