⚙️ 1. Electromagnetic vibration
An electromagnetic coil rapidly pulses (typically 50–120 Hz), causing the bowl to oscillate.
This vibration isn’t random — it’s tuned for amplitude and frequency based on:
	•	Part mass
	•	Friction coefficient
	•	Geometry
	•	Desired feed rate

The bowl doesn’t just move up and down. It moves in a spiral micro-throw motion — tiny upward and forward movements that “walk” parts along a helical track.

⸻

🧲 2. Directional motion from angled springs
The bowl is mounted on angled leaf springs.
When vibration occurs, those springs convert vertical oscillation into a combined vertical + horizontal vector.

That angled motion = forward travel.

No conveyor belt.
Just physics.

⸻

🧩 3. Passive mechanical orientation
As parts climb the spiral track, they encounter:
	•	Cutouts
	•	Rails
	•	Air jets
	•	Dead zones
	•	Step drops

Incorrectly oriented parts fall back into the bowl.
Correct ones continue upward.

This is called mechanical orientation sorting — using geometry instead of sensors.
