Early Prototyping
Early Prototype
Our early prototype is much more different than our final prototype. Originally, we settled for an idea that included magnets to ensure a more flexible skin barrier. However, in the end, we created a prototype that would almost act as an 'extension' to the stoma. Images below are of the early prototype. The final prototype can be seen in the 'Final Deliverables' section
Clay model of how a regular stoma is to look.
Illustrates how a retracted stoma may look based on a clay model.
Clay model of the prototype. The orange clay is meant to show the super absorbent wax that is meant to act as an area for effluent to avoid touching the skin.
The felt fabric illustrates the flexible skin barrier as a part of our prototype.
Clay model of the wax including the flexible magnetic skin barrier (shown by the magnets and the felt fabric).
Complete prototype. The bag has magnets within it and is supposed to represents a magnetic flexible skin barrier in order to reduce likeliness of leakage and ensure a secure skin barrier.
Early vs Final Prototype
The reason why we had settled with the final prototype is that there were some flaws within the early prototype. The early design was just used to 'help' the situation but not completely solve it; essentially it was not full-proof. The final design tackled the problem of the retracted stoma while still allowing the patient (Kenny) to use his preferred skin barrier - which is the regular skin barrier. The final design acts as an extension to the retracted stoma and is made in such a way that it stays in place - it cannot get 'lost' within the stoma but it also cannot be pushed out by the intestine.
Final Design Inspiration
The main reason why we had changed our earlier design is due to how one of my team mates had saw an ad for the DivaCup (shown to the right). The reason why this acted as inspiration is because of our other ideas was to create an extension to the retracted stoma but our biggest concern was exactly how to do so without further complications. Thus, to help fill in our previously blank statements, we based our model upon the DivaCup, or menstrual cup, to finally create a design that acted an extenstion to the stoma.
