|How much engineering goes into a design like this?|
This image is a representation of the hair clip I was referencing in the video. I used this as an example because of a funny story I experienced in the presence of my wife. Engineers, be honest, raise your hands if you ever found yourself in a similar situation. Comment if you are man enough to share.
My young daughter had left her hair ties on the kitchen counter. Not overly familiar with female beauty accessories, I picked up one of the hair ties and actuated it, stopping short of actually trying it out myself. (You can see in the video that I have fairly short hair. The hair ties wouldn't work anyway. No reason to test my theory to get objective evidence as proof. Guys, take note. Putting hair ties in your hair when playing dress up with your daughter is OK. Putting hair ties in your hair to prove an engineering theory is not.) Immediately, my mind went to
- strength of the materials,
- Goodman diagrams,
and it blew up from there:
- yield strength,
- material compatibility with hair products like shampoo, conditioner, spray, gel, etc. -- you wouldn't want your hair turning green;
- raw sheet stock,
- progressive die design,
- heat treat,
- finish treatments, and on and on.
She looked at me like I was some alien entity. "It's just a hair clip," she said. To a "normal" person that may be true, but to an engineer, this is a marvel. There are so many small nuances that had to be considered in the design, yet to still be able to make them so inexpensively. This is the world we live in.
To an engineer, the world is not something that is just interacted with and expected to work. It is something designed, thought of, created, and developed. Someone had to think of this before it even existed. There is an existential connection to everything we contact. Non-engineers can't see it and look at us like we're crazy. Engineers look at them and wonder how they can't be fascinated by it.
Why should you become an engineer?
Because the world is a beautiful place. Learn how to shape it, not just use it.
