Previous Helemet Iterations
Helmet Idea 2: Hard-shell Design
This is inspired by the sponsor's helmet design. The helmet is scaled up for a snugger fit, and holes for the vents and fans are re-created to suit our needs.
The final version would be made using SLS to provide optimal light weight and comfort.

Helmet Idea 1: Skeletal Design
This design has four arms that a vent and a fan attach onto. Then a light-blocking fabric is placed ontop to complete the shape of a helmet. This design is currently looking promising and undergoing testing.
There was two versions made of this design with the only difference being a reduced weight and an improved arms length for better vent positioning on the head.
See the image collection below for testing of the skeletal helmet V1 & 2 on top of the fNIR headset, as well as with an imitation fabric sewed to it and around the fans.

Sponsor's Helmet Design Idea: The images below show the sponsor's helmet design. The vents are simple circular caps mounted on the outside of the helmet, which provided no light blockage and very bad airflow. As shown in the far-right image, small fans were mounted on the inside, which caused loud noise and very little airflow.
-Note also the 4 mounts with magnets. Those are used to attach onto the fNIR/EEG headset.

Vent Idea 5:
The UFO design was iterated on a few times until version 5. This optimized version has much lighter weight and smaller volume than previous similar iterations.
Has the best airflow speed while 99% blocking light from going in.
Team has decided to use this design path for now for all vents on the helmet after comparisons with the previous vent ideas and iterations.

Vent Idea 4:
UFO design, which implements the same geometric features on the inside to allow airflow while blocking light. It was intended as a hot air exhaust vent.
This 1st version was good, but slightly big and not so great with airflow speed.

Vent Idea 3:
One-Directional Vent. It was intended as an inlet vent that can provide good light blockage and airflow.
It proved to be too big, thus abandoned.

Vent Idea 2:
Circular Vent. It utilizes the patented geometry found but in a revolved manner.
Excellent light-blocking. Weak Air-flow.
Too big, difficult to 3D print cleanly, difficult to mount inside the helmet.

Vent Idea 1:
Our team discovered a vent design that utilizes a geometric angle ideal for blocking light.
The below picture is a 3D printed sample of that geometry that showed better results than the sponsor's vent, but was by no means light-blocking.
Sponsor's Initial Vent Design:
This design was made by the Sponsor to try and block light from going into the helmet. It was intended to be used by combining two copies of this vent with a 180 degree tilt.
This design failed as it let in too much light.
