ARC is a shower water flosser designed to fit into the daily shower routine. ARC attaches to the shower hose and uses the existing water pressure, so no electricity or batteries are needed. The handle holds a replaceable four-way water stream head that cleans between the teeth and along the gum line. Three adjustable settings allow a gentle or a stronger water flow, and a multi-function button switches between the water streams. A compact, moisture-resistant storage station with a magnetic attachment holds ARC when it is not in use.

Production Technology
The ARC water flosser is built with durable, moisture-resistant materials, including ABS plastic for the housing and a silicone water seal to prevent water damage. The 4-way water stream head is made of BPA-free plastic and soft rubber for a comfortable and effective flossing experience. It's assembled using injection molding. The device functions using minimal energy, relying on the water pressure from your shower.
Design Challenge
The biggest challenge was designing the mouthpiece to be both comfortable and effective with the water stream technology. I used myself as a test subject, experimenting with different shapes and looking at mouthguard designs for inspiration. I also prototyped various designs using 3D printing to test the fit and comfort. The goal was to create a mouthpiece that allowed the water to reach all areas of the mouth without discomfort or splashing, ensuring a smooth and effective flossing experience.
Project Duration
The project started in January 2024 and finished in May 2024.
Operation Flow
To set up ARC, simply attach it to your shower hose. The water pressure from your shower powers the flosser, and the adjustable settings allow you to customize the water flow for a personalized experience. Press the multi-function button to switch between different water streams, and glide the floss head along your teeth for a thorough clean. The device can be easily stored in the compact, moisture-resistant storage station when not in use.

Inspiration
ARC was inspired by the desire to simplify daily routines and promote healthier habits. Combining the act of flossing with showering makes it easier to incorporate oral hygiene into a busy lifestyle. The goal was to create a seamless, time-saving solution that fits naturally into daily habits, making flossing more accessible and efficient without adding extra steps or hassle.
