Painpoints of Current Ramp

In this project, we partnered with the Northwestern Baja team to create a ramp for testing the suspension of their off-road vehicle. Through discussions with the team's testing director, we identified several issues with the existing ramp: it was unstable, too small for the car, and difficult to transport for testing purposes. Our purpose was to design a ramp that would satisfy these pain points in the current design.

Mockups to Adress the Painpoints

In addressing the initial challenges presented by the ramp design, we prioritized improvements in portability, stability, and safety. Our approach involved creating mock-ups for foldable ramps, ensuring ease of transportation. I personally drafted designs incorporating hinges, which rendered both the buffer and the inclines of the ramp foldable.

Redesign After Feeback

After feedback from Francisco Madera, testing director of the Baja Team, we discovered that the hinges in our design might compromise the ramp's stability. We opted to remove the hinges from the buffer, integrating a triangular support and a metal handle instead, to enhance portability.

We also re-engineered the inclines, replacing the hinges with metal wedges to connect to the buffer through the slits, ensuring a secure and stable assembly.

Final Design

Our completed design, the ‘Buff Twins’, integrated a plywood buffer, completed with slits for incline attachment, a triangular support, and a central metal handle to facilitate easy transportation.

This assembly incorporated two identical inclines, each securely connected to the buffer via steel wedge attachments, ensuring stability and support.

The triangular support, designed to rotate freely around a steel rod, maintained the base's level position during lifting, thanks to a balanced weight distribution within the structure.


Overall, this design not only simplified the ramp's disassembly and transportation process but also enhanced its stability through the strategic integration of metal wedges.
