This project has taught me a number of things, first and foremost how to format onto a website. I've also learned about DFMAs and the engineering mindset that goes into designing an item for the general public. This was achieved chiefly by the disassembly and analysis of the Black and Decker Li2000.

​

It opened my eyes to what engineers think about when they design something to maximize design simplicity while also maximizing profits and consumer satisfaction. It showed me the thin line between a good product and a bad one, and that engineers must consider as many details as possible to make the best product.

​

For me personally, CAD has always been something I find relaxing, so doing more CAD was never a real chore. If anything, I actually enjoyed modeling the gear system and watching it come together with gear pairing into a full working mechanism. 

​

The most interesting parts of this project, if not the CAD skills I've had to use along the way, would probably be disassembling the screwdriver and understanding each component, and understanding the engineering decisions made behind choosing individual parts (DFMA). These individual parts make the whole, and it's cool to think that every little detail and decision regarding parts was deliberate in order to make the best product possible.
