Simple, yet effective Top-Down Design approach


Every product on the market always starts with one thing in common---a problem in need of a solution. Yesterday I had a problem that I was in dire need of a solution. A little bit of background on myself lately; I have been going to the gym trying to lose a few lbs (down 18 lbs in two months), as being a drafter seems to make you fat from sitting all day. It was suggested that I start taking creatine supplement to boost my muscle gain, so I went to the store to pick some up. To my dismay, I went to mix the powdery substance per the directions of "1 rounded teaspoon" and there was no "scooper" to measure that out. I was at the gym and had no idea of knowing if I had just poured out a rounded teaspoon or not!

So I done what any normal person would do, I went and bought a teasp........I mean I designed one in Solid Edge and 3D printed it on a $26,000 Stratasys printer.


To do this easy project, I used a Top-Down design technique in Solid Edge ST8. The first thing I done was to model a representation of the interior volume of the scooper. I needed to be exactly 1 teaspoon. I knew I wanted the I.D of the cutout to be around 0.75". Mathematically I could figure out what the height needed to be to equal 1 teaspoon, but I wanted to use a feature I LOVE in Solid Edge called Goal Seek. I modeled a cylinder that was Ø0.75 by 1" tall and saved it; the 1" just being a placeholder. Then I gave the model some random material because in order for Goal Seek to work, a material HAS to be assigned.
