ECE110Honor Project
Introduction
Statement of Purpose
In ECE 120, professor Dong San Choi said a student could only choose two of the characteristics below: Social life, GPA and enough sleep. Most of us chose social life and GPA, discarding the sleep choice. That is where the problem generates: when students do not have enough sleep, they can barely get up on time in the morning. So we want to develop a waking-up system to help students jump off from their beds. Using our system, you can still meet with your friends and go to work hard on your courses without worrying about being late.
We implemented a series of contraptions. Using your existing cell phone as a trigger and with the help of sound and pressure sensor, we are able to force students to get off of their beds and never go back to sleep again.
Background Research
According to extensive interviews with college students, we found out that most students have a hard time getting up even they set a series of alarm beforehand. A lot of students, including me, set more than 6 alarms before the actual time that they wake up. By the time they wake up, the time remain is limited, so they are likely to skip breakfast for classes or skip classes for breakfast. The worse scenario is that they grab their phone, they off their alarms, and go back to sleep again.
Flow Chart
System overview
The user will set their alarm as usual, and they will put their phone on a specific charger dock. the doc will contain 3 parts: charging port, sound sensor, and a pressure sensor. The charging port is for charging the phone obviously; the sound sensor will be triggered when the alarm sound; the weight sensor will be triggered when the user removes the phone from the bed.
At the stage that the sound sensor was triggered, we will use the motor to winch up your quilt and activate a circulation fan to ensure that you will have fresh air and don’t have any intention to stay in the bed. The light will also be open at this stage. If it is technically possible, we will also winch up the window shades (the window shade in our test dorm is not working perfectly, so it might be hard).
Then, when the user removes the phone from the dock to close the alarm (which ensures that they are away from the bed), the pressure sensor will be triggered, and we will tilt the mattress towards the wall more than 20 degrees using screw pole motor (air piston will be too fast and too complicated for this) . So nothing on the bed will fall on the ground, and it is nearly impossible to sleep on the bed again (the screw motor is connected using some wood panels, if the user goes on the bed again, even if he or she can withstand the tilted mattress towards the wall, the wood panel will collapse)
At this time, the user is out of bed, and will not be able to return to the bed. And our job is done. Returning the machine to the original state involves too many conditions that we will better leave it as it is. (To be discussed with Ta)
Possible Challenges
- The project includes much mechanical stuff, which might be hard to manufacture
- We want to avoid trigger the sound sensor if the sound is not the alarm.
- The entire setup will be hard to return to the original state.
Parts
window shades

Reports
ECE110 regular section report will be available upon request.
Physical Construction
PS: I change the design during the process of doing the project, so the project finally used a sound sensor and a flex sensor. The active components now include a light, a curtain, and a mattress.
