Happy New Year Everyone!
The PHS InvenTeam has been hard at work prototyping our wallet for the visually impaired. Between this, several exciting opportunities offered by local organizations, public presentations of our progress, and our Mid-Grant Technical Review coming up next month, our hands are full!
New developments in the wallet include the completion of our third prototype of the bill sorting mechanism. In our original concept designs, we had envisioned a funnel attached to a rack and pinion placing each bill into its corresponding slot. However, this method used a lot of space and energy moving the funnel in other unnecessary slots, which also decreased accuracy. Our second prototype involved a piston lifting the bill into the correct slot. While this took up less space than the rack and pinion, the piston itself was rather pricey and used far too much electricity to lift the funneling mechanism into place. The third prototype was a hybrid of both previous designs and introduced the idea of compressing the bills already inside the slot in order to add the new one. Although this design seems to work, we are beginning work on the fourth prototype, which uses a rotary motor to distribute bills while a compression mechanism holds the sorted bills in place. We are optimistic that this will be our final design.
