For my Senior Design Project, I worked alongside two other engineers to design a fiber shredder for the Women’s Relief Initiative. The shredder will be used to turn raw corn husks into a pulp that the WRI wil use to produce sanitary pads for women in rural West Africa. The goal in designing the shredder was to maintain the production capabilities of common pulp making machines such as a hollander beater while decreasing its cost and water consumption, and eliminating the need for an electrical power source.
Assembly and Exploded View of Design
I was responsible for researching and designing the hand crank mechanism (shown to the right) that allowed for us to eliminate an electrical power source as well as the container that helped to reduce overall water consumption by 57%.
Additionally, I created CAD models of each component and used FEA to perform static load and fatigue analysis on the components to ensure that they could achieve the 5 year lifespan our sponsor desired.

Upon design completion, our team developed a technical report including our research, the rationale for our design decisions, a bill of materials including estimated material and labor costs, and detailed manufacturing instructions for the WRI to use to build the working device.
