Mechanical Pixel Display for Flat Moon Phase Timepieces

The patent transitions from a three-dimensional spherical representation to a two-dimensional flat representation by using pins that move vertically within a flat perforated plate. The pins' upper surfaces, when visible through the holes, create the optical illusion of lunar phases without requiring the height of a actual sphere, thus resolving the contradiction between realistic representation and height constraint.

Instead of using an actual three-dimensional moon sphere, the patent creates a two-dimensional copy or representation of the moon phases using pins with different surface treatments (silvered, blackened, or transparent). These pins replicate the visual appearance of lunar phases in a flat configuration, achieving realistic representation without the height requirement of the original three-dimensional object.

The patent divides the moon phase display into multiple independent segments - individual pins representing different portions of the moon. Each pin can be controlled independently by separate cam mechanisms, allowing simplified control of complex moon phase representations. This segmentation reduces the complexity of moving entire lunar globes while maintaining accurate phase representation.

The patent replaces the complex mechanical system of a moving lunar globe with a simpler pin-based system controlled by cam mechanisms. The cams convert rotational motion into the precise vertical movements of pins, providing accurate moon phase representation through a less complex and more reliable mechanical system that eliminates the fragility of spherical mechanisms.
