A long time ago, engineers were trying to design the perfect ceiling fan. First they tried four blades, but the fan started shaking. Then they tested five blades, but the motor overheated and used too much electricity.
Finally, they tried three blades… and it worked perfectly. It gave the best balance of speed, stability, and efficiency.
That’s why many ceiling fans today are designed with three blades.
Sometimes the best inventions happen not by adding more… but by removing what isn’t needed.
