I designed a self contained system to allow astronauts to be in a pressurized space suit (or even an unpressurized suit) and be able to eliminate waste to temporary storage bladders contained within their modified boots. The system handles moving waste from the body and transporting it without requiring gravity or any external vacuum supply that would compromise the air seal within the suit. As an extra feature, I also included a way to purge the stored waste from the storage bladders and still maintain pressure within the space suit. The advantages of this system is that it can operate with the MACES, the EMU (for space walks), and in pressurized rooms too.
The limitless possibilities in space exploration inspired my innovation of the astronaut "Duty Boots" to remove waste; waste disposal is important because of health and has made a long term impact.
I looked at the current solutions used by NASA and figured I could at least think up something better than what they use now.
I started very late in the challenge since it started in early October, but I did not know about it until late November. I entered on December 3 and had, what I think could very well be a winning solution, turned in by the December 20 close. In addition to figuring out my idea, I also had to learn enough about a 3D modeling tool called Blender to convey my idea in an understandable format. My solution went beyond solving the MACES suit waste handling, it is easily adapted to the EMU and to just normal astronaut everyday waste handling. Possibly preferred over the current Zero-G John.
Thanks to HeroX for providing such a valuable service of letting people who want to contribute solutions a place to have them seen.
