Joining and Assembly of the Tuan Shan: How Ribs, Handle, and Face Come Together

The tuan shan's strength and smoothness come from how its ribs, handle, and face are joined. Mortise-and-tenon handle joints, evenly bound rib clusters, and correctly tensioned face mounting come together in an assembly that opens smoothly and holds up over years of use.

The Scenario: Three challenges in assembly

Tuan shan assembly faces three challenges:

Pain Points

• The handle-rib joint must stay tight through opening and closing without loosening;
• Rib clusters must spread evenly so the face mounts flat and the arc is true;
• Face mounting must hold tension without tearing or pulling loose.

The Solution: Three assembly techniques

Assembly uses three techniques:

1. Secure handle-rib joinery Mortise-and-tenon or pinned joints keep the handle-rib connection tight.

2. Even rib fanning Bind and fan ribs evenly so the arc spreads true and the face mounts flat.

3. Tension-correct face mounting Mount the face at the right tension so it stays taut without tearing.

The Result: A fan that opens true and lasts

With these techniques, the fan opens smoothly and stays intact for years. Sound assembly is what separates a fan that lasts from one that loosens.
