Rib Spacing and Opening Mechanics of the Tuan Shan: How the Fan Opens Smooth and Moves Air

The way a tuan shan opens and moves air is set by its rib spacing. Evenly spaced ribs of the right count let the fan open smoothly, hold a round shape, and fan with a steady breeze. Understanding rib spacing helps makers build a fan that works as well as it looks.

The Scenario: Three challenges in rib layout

Rib spacing faces three challenges:

Pain Points

• Uneven spacing makes the fan open stiff or wobble instead of rotating smoothly;
• Too few ribs leave the face unsupported and floppy, too many add weight and friction;
• Rib width and spacing together set how much air the fan moves with each wave.

The Solution: Three rib-layout solutions

Careful rib layout offers three solutions:

1. Even rib spacing Spacing ribs evenly keeps the fan opening smooth and the round shape true.

2. Right rib count Choose rib count to balance support against weight and friction.

3. Balanced width and airflow Match rib width and spacing so the fan moves a steady, comfortable breeze.

The Result: Smooth opening, steady breeze

With these solutions, the fan opens smoothly and fans with a steady breeze. Good rib spacing is what separates a working fan from a mere decoration.
