2. Problem Statement & Design Goal
Problem Statement: People driving while intoxicated is a serious issue for public and driver safety. A large number of driving fatalities happen as a direct cause of alcohol. o

3. Problem Statement & Design Goal
Design Goal: Design and develop a product meant to bring safety into the hands of drivers by disabling them turning on their car on if the device detects that the driver is too intoxicated to drive safely. r

4. Features/Criteria

6. Background Research & Investigation
Questions to Consider
How do we detect the alcohol level of a person?
How will our device be able to communicate with the car?
How much will the product weigh?
What materials will the product be made out of?
What are some existing solutions? o

7. Background Research & Investigation
Existing Solutions:
SCRAM anklet
Fuel cell technology
Court appointed
Measures BAC Periodically o

8. Background Research & Investigation
Car Breathalyzer
Uses random checks
Requires blowing into the device
Reportedly, very faulty r

9. Background Research & Investigation
BAC Detection
Detection pads that register alcohol consumption in the form of electrical current would be implemented into a key
Car Communication
A chip would be installed in the car that communicates using NFCs to either allow or disable the engine to be turned on to another NFC set inside the key device
Product Weight
Product must be light and easy to carry
A set of car keys is approximately 3.5 ounces, or 0.2 pounds
Product Materials
The key would be made of brass aluminum alloy
The head of the key could be made out of polymer, ensuring a cheap production cost r

10. Background Research & Investigation
Lessons Learned
It is entirely possible to implement our own features from existing solutions into our own
A key is expected to be pocket- sized and lightweight
Grooves should be on the sides of the key for an easier grip r

11. Possible Solutions Solution 1: BAC Key
Transmitter chip inside of the key
Uses detection pads to analyze the BAC of a person
Key transmits a signal to a chip in the car’s engine via NFC (Near Field Communication
Signal locks the car door if the user’s BAC is too high o

12. o

13. Possible Solutions Solution 2: Watch Detector
Smart watch that detects BAC automatically at a
Constant rate
Alerts the user if their BAC is about the legal
Limit to drive
Screen on the watch displays all information that
Needs to be shown to the user o

14. o

15. Possible Solutions Solution 3: Door Monitor
Monitor that is placed on the entrances to bars
People that leave the bar are required to scan
Their thumb on the smaller screen
The monitor determines the user’s BAC and
Displays the level on the larger screen
Plays an alarm to alert the owners of the
bar if the user’s BAC level is over the legal
limit r

17. Choosing the Best Solution
Solution A, the BAC Key, gained the most points in the decision matrix
Criteria weighted by importance r

18. Project Timeline
Timeline used to keep track of deadlines, milestones, and tasks
Essential for better organization o

19. Development Work Major Design Decisions Roadblocks & Setback
The device could be simplified in terms of technology
Rather than having three lights, the product only Needs one light to show all three of
The indicator colors, depending on the situation
Roadblocks & Setback
Encountered the issue of aesthetics
Figuring out how to detect BAC without breathing o

20. Development Work Final Product
the end result of our product turned out more effective and appealing than the initial ideas for the product

24. Evaluation The BAC key gained the most points total criteria.
But, the product also does not have the most advanced components, and the shape of the key is not the most appealing.
The criteria that would require field testing are ease of use, comfort, and portability. Price and safety would be analyzed through lab testing. o

25. Recommendations & Future Work
The next step in producing the product is to improve its features and make it even easier to use.
To get our product manufactured, we would need to get hired be a car company so we could implement our security system in that company’s mass produced cars.
Changes to our approach include spending more time into researching the different ways that BAC could be detected, and understand the mechanics of cars in greater depth. r
