It all started with just one person — me.
Back then, I was living in a small rented room, struggling through unbearable summer heat. Whether I was outdoors, biking, or doing chores, I kept wishing for a truly hands-free, lightweight, and quiet fan that I could wear anywhere.
But every fan I found was either bulky, noisy, or ugly — none of them felt right.

So, I decided to build one myself.
I began from scratch, designing the structure and 3D-printing prototypes, taking apart old computer fans for parts. By day, I taught myself design software; by night, I soldered wires, adjusted motors, and tested airflow.
It was just me — designing, sourcing, assembling, and learning through countless failures.

Soon I realized that functionality alone wasn’t enough.
If I wanted to create something people would truly love, it had to look as good as it felt. So I started studying how to apply for an industrial design patent, refining my CAD drawings over and over again. Every curve, every button position was redrawn until it felt perfect.
Finally, after the final submission, I received my official design patent certificate.

That moment meant more than just approval — it was the realization of a dream built with my own two hands.
Today, this portable waist fan is helping more and more people stay cool and comfortable through the hottest days.
And I still remember that version of myself, soldering wires in a tiny room.
Because everything began from one simple idea:
to bring comfort and freedom to people, even in the heat.
