The sketch model for Lock In shows the concept of how the final product will feel. The mini basketball hoop aesthetics and basic concept for key entry and retreival was demonstrated here.

The critical function proved that our door mechanism and key detection methods would work. A lego 4-bar mechanism moves the door and releases the keys as intended and the pressure sensors detect the keys reliably. Additionally, a flap in the middle of the model shows how keys can be diverted for multiple users.

Lock In combines basketball and key storage in a way that has never been done before. It motivates users to store their keys in the same place every single day and is easy to use. A countdown sequence is triggered by a reed switch, which displays the time left. 

Upon a made shot, iconic buzzer beater announcer clips are played over a loudspeaker, and LEDs indicate that a compartment is occupied. If a shot is not made in time, the system draws from a number of NBA blooper clips that roast you for not getting the keys in the bucket in time. 

An automated diverter uses the pressure sensor data to detect if a compartment is occupied, and routes your keys into their own space, so up to two users can leverage this product. 

Retreiving your keys is as simple as the press of a button, which activates a linkage to open the door containing your keys.

Our team is proud of the final design of our alpha prototype. The hard work and dedication that went into creating the final product was the result of hundreds of combined hours over the course of the semester. The visual design evokes feelings of playing backyard basketball, and the shot clock and audio feedback make Lock In fun to use.
