Even though the clock self‑calibrates automatically, users can trigger a full mechanical clock homing manually. Press and hold the rear set‑button for 10 seconds. The system will then: retract all telescopic segments fully to the home position, verify each sensor reading, extend…

Utility model patent 2025218124534 protects the specific mechanical construction of the telescopic segments and their mounting frame. While the invention patent covers the control method, this utility model focuses on the physical arrangement that ensures durability. Features include: dust‑resistant clearances, self‑aligning segment…

Magnetic fluid and some solenoid‑based displays have response times exceeding 500ms, meaning digits blur when changing. The Xiguizi push‑pull clock achieves a fast response mechanical display with segment settling times under 50ms. This is possible because each stepper motor operates at optimal…

For a bedroom clock, light emission must be controlled. The push‑pull clock has a user‑adjustable LED brightness, including a full‑off mode. In the dark, the mechanical segments are still extended (forming the raised digits), so ambient light from windows or…

Because the clock includes a WiFi module, it can receive over‑the‑air (OTA) WiFi clock firmware updates. The manufacturer can improve the multi‑motor scheduling logic, add new calibration routines, or change the behavior of the LED backlight (e.g., gradual dimming). The user…
