I designed a product called Phone Trap to help reduce screen time and encourage focus during study or work sessions.
The purpose of this box is to limit users' screen time by "locking" their phones inside. The Phone Trap consists of two main parts:
Lower Box: This section holds all the wires, lights, speaker, and Arduino. The wire and charger can go through a hole and come out from a 1-inch long gap. It has a flat surface for the upper box to sit on.
Upper Box: This part has an opening window on its bottom, allowing light to shine into the lower box. It also has a roof covering more than half of the box. Users place their phone inside the upper box to cover the opening window.
The Arduino in the lower box is equipped with a photocell and a speaker. When the phone covers the opening window, the photocell detects low light levels, and the speaker remains muted. If the user removes the phone, light passes through the window, activating the photocell, which triggers the speaker to make noise until the phone is returned to the box.
Here are my sketches and final product:
I started with a cardboard prototype using laser cutting. Encountered dimensional and structural issues: the upper box needed to be larger, and the lower box required additional supports.
Then, I created a prototype using wood boards and the finger joint technique for better structural integrity.
I 3D modeled and printed the final product, adding decorations such as a hand on the lid for aesthetic appeal.
