For my final project in Engineering Design I, my project team and I chose to help a user with paralysis who has had difficulty giving his service dog treats to keep him motivated. The previous design restricted armrest mobility and had the potential to spill all the treats out of the dispenser. We aimed to design an effective method for storing, carrying, and dispensing dog treats that he can use on a daily basis.

We created a design that could be easily attached to a wheelchair and cleaned. Overall, this project provided a great introduction to designing a product for users and ensuring that user-centered design is at the forefront of engineering design.

For my final project in Materials & Manufacturing I, my project team and I was tasked with enhancing my understanding of material properties by generating and utilizing stress-strain curves. These curves were obtained through testing specimens and imported into SolidWorks for simulation analysis. By evaluating and comparing the performance of different material models—linear and elasto-plastic— we aimed to understand their impact on simulation results.

To achieve this, we conducted material tests using the Instron machine with dog bone test specimens, extracting key mechanical properties. Using a cantilever beam as a case study, we analyzed the performance of each material model across simulations, highlighting the differences in behavior and accuracy. This approach allowed us to explore the practical applications and limitations of these models in engineering design.
