I started this week by attempting to open up a faulty hairdryer in my home. After trying the first few days to get it open, I was only able to get a few screws off and pry off part of the handle. I couldn’t even get past the handle the first day, and in order to get part of it off the second day, it required me to hammer a flathead screw driver through a line running down the middle of it. I tried prying off the rest with a prying tool, but the closer I got to the top of the hairdryer, the harder it was to move it because of how stuck it was. I tried continuously, even attempting to use another blowdryer to heat up the one I tried taking apart in case there were any adhesives keeping it together, but it didn’t work. Finally I figured if I broke open the hairdryer, it wouldn’t matter because it’s faulty anyway, so I decided to get the hammer again and started hammering at the top. To my surprise (and frustration for having spent so much time trying to get it off before) the top popped right off.

I inspected it and was able to see where the buttons were, what they were connected to, how some wires were soldered on to a piece of metal to make them work, etc. I noticed a lot of copper wires as well, which I assumed was to make it easier for heat conduction.

After taking it apart further, I noticed there were several springs encircling a piece of metal around the front of the hairdryer. I assumed that also had to do with heat conduction.

I then attempted to design the bottom fan-like component of the blowdryer on the CAD website I have been using. I will attempt to do it for all parts of the blowdryer, but this one took me pretty long because I didn’t know how to make a cone and have pieces protruding from it. But this is the best I got so far.
