Base Geometry<\/strong><\/h1>\n\n\n\n

The anti-slip design features four fins added to the existing axillary crutch base geometry, which serve to increase the surface area and points of contact made with the ground during ambulation. Each fin includes four ridges for additional traction during the swinging phase of ambulation. Current axillary crutch bases have a circular face at the bottom of the base, so the surface area of contact between the base and the ground is limited to the leading edge of the circular face during the swinging phase of ambulation. However, this design adds an additional 1.67 in2<\/sup> of surface area on each fin to allow for a greater surface area of contact during the swinging phase of ambulation and reduce slipping potential.<\/p>\n\n\n\n

Irrigation System<\/strong><\/h1>\n\n\n\n

The anti-slip design also features four circular cuts on the underside of the base component for added traction, with four straight-line cuts beginning at each corner and ending at the center of the base. These cuts serve as irrigation channels for any fluid trapped underneath the base, allowing the fluid to to drain and further reduce the slip potential.<\/p>\n\n\n\n

Decision Matrix 1. The team selected the four fins with a circular traction design.

Decision Matrix 2. The team selected Smooth On KX Flex 60 for the base material. While Smooth On Task 14 scored equally well, Smooth On KX Flex 60 was selected due to its similar hardness to current axillary crutch bases.
