Electro-Mechanical Blocking Actuator Slit Design

The patent introduces a dynamic blocking mechanism where a blocking element can move between a first position (blocking the slider) and a second position (allowing slider movement). This dynamic structure allows the actuator to switch between locked and unlocked states, preventing manipulation while maintaining energy storage capability. The blocking element responds to motor activation to change positions, providing active protection against unauthorized manipulation.

The patent changes the state parameter of the blocking element between two distinct positions. In the first position, the blocking element physically obstructs the slider's movement path, preventing any displacement regardless of spring force. When the motor is activated, the blocking element transitions to the second position, allowing the stored spring energy to move the slider. This parameter change (position state) resolves the contradiction by controlling when the stored energy can act on the slider.

The patent applies preliminary anti-action by positioning the blocking element in the first position before any external force is applied. This blocking element pre-empts potential harmful effects by physically preventing the slider from moving, even if the spring is compressed by external forces. The blocking element acts as a preliminary barrier that must be removed (by motor activation) before the slider can respond to any forces, including harmful external forces.

The blocking element serves as an intermediary between the spring and the slider. Instead of allowing the spring to directly act on the slider (which would permit manipulation), the blocking element mediates this interaction. When in the first position, it decouples the spring's potential energy from the slider, preventing unauthorized movement. The intermediary blocking element thus protects the system while allowing controlled operation when the blocking element is in the second position.

The patent segments the constraint function into two independent components: the pin provides radial constraint (first function), while the blocking element provides axial constraint (second function). This segmentation allows each component to specialize in one direction of constraint without interfering with the other. The pin maintains sleeve stability in the radial direction, while the blocking element independently prevents axial displacement, together providing comprehensive positional security.

The patent applies asymmetry by using different constraint mechanisms for different directions. The pin (cylindrical element) naturally constrains radial movement through its geometry, while the blocking element (separate component) constrains axial movement. This asymmetric approach uses the most appropriate mechanism for each directional constraint, optimizing both radial stability and axial security without over-constraining the system in a symmetric manner.
