Thalassa

Thalassa is a snorkeling set for amateur snorkelers, redesigned with simplified components and biomimicry-driven features for a safer underwater experience.

This project was originally developed as a team project called AquaRevive in a sustainability course. The concept direction, redesign, and all visual work shown here reflect my independent design decisions during the middle and later stages of the course and beyond.

Disassembly

Smaller Diameter, Less Dead Air Space

The problem with larger barrels in snorkels is two-fold: air resistance and rebreathing carbon dioxide. I ideated the snorkel to have a smaller diameter, with two tubes wrapping around the user’s head for a streamlined experience.

Smaller Surface Area, More Power?

Inspired by the superior fluid dynamics of tubercles on humpback whale fins, I used flow simulation to test the performance of tubercles applied on shorter.

Testing Concept Validity

To test the validity of the whale tubercle fins, I used flow simulation in SolidWorks to check their performance compared to a regular fin and propeller with tubercles.

The tubercle fin diverted the flow of water into narrower streams, resulting in higher velocities. This improves swimming efficiency and reduces fatigue while snorkeling.

Goggles

The glass lens is molded directly to the silicone skirt instead of the standard plastic frame. This frameless design makes use of less parts to provide more comfort and a better fit.

Snorkel

The dual-tube snorkel wraps around the head for a streamlined fit, reducing movement and improving airflow and water purges.

With the bracket, the loop snorkel remains neatly constrained around the neck when not in use. The silicone mouthpiece includes a dental bridge to reduce jaw fatigue and eliminate the need to bite down too tightly.

Fins

The slightly uplifted blade of the fin makes it easier to walk on land, while the tubercle bumps on the edge of the fin blade increases swimming efficiency with less material.
