This report documents the final product of Jonathon’s new lightweight stroller. The Mechanical Engineering team from Cal Poly, High Strollers, began the project to create a lightweight stroller for the project sponsor, Nina Aguayo, and her son, Jonathon Aguayo, in Fall of 2018. Jonathon is diagnosed with Delayed Brain Development and Hypotonia with some characteristics of Cerebral Palsy. He has a 50lb high intensity stroller to go to and from school. Mrs. Aguayo needed a stroller that is easier to transport while still meeting all of Jonathon’s needs. The re-designed stroller will make leisurely outings for Mrs. Aguayo and Jonathon manageable. The following document steps through the design process and modifications made to a jogger stroller to meet Mrs. Aguayo’s and Jonathon’s needs. Included is background research conducted on customer needs, current product research, and technical research. The problem statement constructed has been specified in detail along with a boundary diagram and Quality Function Deployment diagram. Design decisions and concept prototypes were created following this research. The final design chosen is explained in detail along with the manufacturing process. Testing to verify the design is explained in detail. Lastly, the management process is laid out along with conclusions on the project and recommendations to the user.
