As I joined this paper late I unfortunately have only done one of the experiments. This was experiment 4.

This movement reminded me of a breathing lung of sorts and inspired me to make something related to breathing.

After watching Star Wars The Phantom Menace I decided I wanted to pursue an underwater breathing device.

I decided to look more into different Sci-Fi devices similar to this to get more inspiriation to see other devices I could base mine off

Although Dune did not use a water breathing device I still found the concept of having it attach into your nose interesting and saw potential in this.

The method used in Harry Potter is very unique, I found it very interesting how they made a new organ for him that allowed him to breath under water and transformed him to be similar to a fish with gills. I can imagine a lot of different ways I could use this idea of growing gills somewhere along the body to allow the user to breath underwater.

The device used in James Bond is very similar to what was used in Star Wars as something placed into the users mouth that allows them to breath. This is a common concept but I see an issue with the cost of printing. I also think it would be uncomfortable to have to hold it in your mouth.

I decided from these that I would rather have something that fits onto your skin like the Harry Potter method rather than one that gets held in place inside you like in Dune or James Bond.

I then decided to look at more devices that weren't just from movies and instead actual and conceptual medical products as well as other Sci-Fi designs.

I found these concepts very inspiring. I really liked the idea of a product that attaches to your body or a wearable device like a watch or ring that is easy and convenient to use. This is a lot more convenient to use than something that you would have to carry with you and then put into your mouth like what is in most movies.

My next challenge is to decide where on the body I would like to have mine positioned. The way my device works is it filters oxygen from the surrounding water and inserts it directly into an artery to be pumped to the heart and around the blood stream.

To find a good position I used Complete Anatomy to look at where the arteries are on the body.

Based on how close the arteries were to the skin and how practical the positioning was I found 5 different areas I could potentially have my product be located.

Using some blue tack I made simple "mock ups" of the product on my body to see what it would be like to have it on you and to see if the position worked or not.

Although I really liked the idea of having it attached onto your body I have decided to pursue the ring concept. I chose the ring as it would be the most convenient as it works if you just place it on and is easy to remove rather than something attached to you. It will also be easiest to hide the tube connecting to it to blow the air in and out if I do the ring whereas it would be difficult to hide it in any other position.

I now had to think about how I wanted my object to move. I drew a lot of inspiration from the way the frogs vocal sac moves. This movement also reminds me a lot of experiment 4 so I decided I would like to adapt it into my design.

As I am going to use experiment 4 in my design I decided to test how it would work. Since I have the Experiment still I simply stuck it onto a ring to see what it was like. 

This worked rather well yet I noticed that occasionally my middle and pinkie finger would bump into it. Since it was stuck on loosely with blue tack it would fall off however if its made of solid plastic I won't have this issue. I still decided that when I design it I will shrink it down a little bit so that its not as annoying.

I then used blue tack to make a Mock ring so that I could test it with portions closer to what I wanted rather than being stuck with the one from experiment 4.

This was much better sizing and allowed me to get a good idea of how I should portion it.

I measured my ring that I bought to get the measurements for the design which came to 19 mm. With this I knew how big I had to make the ring and what size to make the part on top. 

One thing I considered was how to get the oxygen into your body. The easy solution I came up with was small needles that insert inside of you. I tested out different styles but decided not to overcomplicate it and just used one.

With my final idea of how it will look I drew two versions of my design. One that is what I will actually print with no needle and a hole for the air and the other one was what the product is meant to be with the needle.

I then drew down a whole bunch of different designs in my book to get an idea of where to go with the design.

With these in mind I grabbed my favorite aspects of each design and developed a ring on Fusion 360
