Design Modeling
First, we explored alternative designs. We started with four main ideas, other than our original design. We knew we wanted to have a corset pattern and sticky skin-safe adhesive. Our first idea included adhesive buttons that would be stuck in two straight lines.Hooks would be included on each button in order to lace up the string in a corset design. This design causes least irritation to the skin, but is not as secure as the others. The ziptie box slide is our most secure design, which features an adhesive box, with an open space for the wound. The stitches are looped on both the left and right in a corset design. Then, the top and bottom zipties are tightened to aid wound closure. While this is heavy duty, it is less flexible for areas on the body that bend, like the elbow. The third design is raised buttons. This design includes two adhesive strips with raised hooked buttons. When the thread is laced up, it is raised in order to avoid any painful contact on the skin, This is not as secure as other designs, and could potentially have trouble keeping the wound tightly closed. Finally we have the ziptie pieces, which breaks up the concepts of the ziptie box in order to provide more flexability.
After a series of tests, we decided that this design would be the most effective and functional. This design features silicone strips with metal hooks attached, in which suture thread is laced through. After the silicone is adhered to the skin, the thread is pulled and the device pulls the skin together. We used fusion 360 to create 2D and 3D models of the stitches.
Finally, we created a marketing design. Here, we see what the product packaging would look like via Fusion 360.
