The project addresses this challenge by taking out the psychological and health concerns about pathogens on the external surface of packages. It provides biosafety and security when receiving said package by a thorough ozone cleaning process. Therefore, it's a way of popularizing an only-lab device, allowing it to be used in a daily routine which can assist regular people at homes, offices, industries and companies.
During this pandemic, receiving a package always required us to clean it first, or even leaving some aside for the lifespan of SARS-CoV-2 in different surfaces. Facing this constant mission of avoiding a possible infection has caused a big toll in the psychological health of many human beings. Our project main objective is to guarantee the biosafety of packages when they arrive in the destination, easing the receiver concern about any microorganism in the package.
The space agency data used were articles and documents describing compromised missions due to contamination and techniques used to keep most of the material received in facilities as clean as possible. This project has used Fusion 360, Tekla Structures for development. We had some problems during the development, mainly in the search for a viable and original solution to the contamination problems faced through the years. The primary focus was to develop a truck with a container acting like an ozone chamber, but we scrapped this idea and changed it to an ozone chamber to attend the reality in any desired facility.
