In this project I desiged a fire extinguisher for public use in an aquatic life shop. This project is only intended to put out a small starter fire. I looked at the project from a functional, ergonomic perspective, having to consider how someone might approach the product, particularly in a critical emergency situation.
For my final design I came up with a conch like shape because I wanted it to fit into the environment of a fish store. Because of this shape I was able to use the lip of the shell as a safety mechanism and then put the trigger inside so the user has to slide their hand into the shell.
Around the rim of the fire extinguisher there would be a system to gauge how much liquid is left inside of the container. When the color turns red the vessel is close to full and as it loses liquid the band will become clear.
