|Mailbox with delivery detection and notification
Problem: Sometimes people may forget to check their mailbox for some important messages about their cars or other stuff and it is very normal that people are waiting for something in the mailbox and it is really annoying to check the mailbox several times a day for some important mails.
Solution: We want to design a smart mailbox that can remind people when the mailbox receives a new mail. This mailbox can detect if there is a new mail received in the mailbox
and send a notification to peripherals. Besides, this mailbox is using solar power.
[Subsystem #1:] Sensing System
There are two layers in the mailbox, one is the receiving layer and the other one is for the homeowner to put the mail waiting for picked up.There are weight sensors in both layers. For receiving layer, there is a weight sensor to sense the weight change and a counter to count the number of times does the sensor sense the weight change to track the number of new mail. On the other hand, we also consider a light sensor to detect brightness changes since mails are turned in mostly in day times.
[Subsystem #2:] Motor System
A motor can be used to control the door of the mailbox. After receiving the signal from the user’s phone, a motor will start to open the mailbox door. So we don't have to always bring the key for opening the mailbox. It needs verification and mobile implementation that can communicate with the mailbox.
[Subsystem #3:] Notification System
The part of system allows us to give the notification to users once the Sensing System gives a positive feedback. It will push the notifications This part is connected to peripherals indicating if there is a new mail waiting for picking up. The peripherals include moblies phones or a dock that can put inside home and shows the status of mailbox.
Criterion for Success and Challenges:
Criterion for success means that a good interaction can be established between users and the mailbox; users can rely on the smart mailbox’s notifications as the credible information for their incoming mails. This project will make the experience of picking up new mails a better one than before.
The challenge of this project will be how do we detect multiple mails are being put in the mailbox at the same time and design the way that mailbox should communicate with peripherals. We also need to design a perpherials that can show the status of mailbox other than pushing notifications to phones.
