Porta Potty Final Designs

After doing a bit of voting, our group came up with these drawings consisting of what we believe makes a better porta potty.

This group consists of -

Colby Paul
Nick Hornbacker
Kelly Harper
Ron Romero
Willtham Thammavong
Blake Sleight
Daniel Cushing
Brendan Wanlass
Ben Turner

The initial drawings consisted of these:

These were given to Kelly to pretty up and give a finalized system.  They are included on his blog, but I will include the drawings here:

These ideas will be presented in class.

Porto-potty Design

Given the first task of coming up with a porto-potty design fit to better itself, our group spend a bit of time figuring out the key complaints the standard design had.  After discussing what was wrong, we narrowed it to four main subjects.

-Safety
-Disposal
-Smell
-Transport

Everyone picked one of these features to focus on for design aspects.  I myself picked disposal, or how the "waste" can be taken out of the potties.  I went and asked those who have tried a porto potty on easier methods of retrieving and disposing the waste, given the current method is to suck it straight through a large hose.

After asking, I came up with these sketches:

 

These first designs show off two main methods.  A retrieval tray that can be switched out with a clean one once it is full, and a reservoir where more than one potty can be connected to.  Included are suggestions as to how the reservoir could potentially be underground.

This goes further into the reservoir idea by having it connect to the back, and gives it another tray like feel with the first design.  It also shows methods as to how the waste could be pushed into the tank.  Could we have a conveyer belt do it, a vacuum, or a mechanism actually push it in?
