High-level Design Goals
High-level Design Goals
· Adjustability - Account for drivers with different heights by designing the pedal tray to be adjustable
· Mounting - Design mounting holes for all required sensors and components
· Weight reduction - Optimize for weight while maintaining structural strength.
· Streamlined manufacturing - Implement design and manufacturing techniques to decrease production time and lower associated costs.
· Cost reduction - Utilize cost-effective materials that retain the required strength and stiffness without sacrificing performance (FOS, Deflection)
Single Wall Prototype
Single Wall Prototype
To evaluate the feasibility of a single-wall throttle pivot concept, a 3D printed prototype was created. This design offered potential benefits in both assembly simplification and weight reduction. However, stability concerns emerged during testing.

Manufacturing
Manufacturing
The pedal tray was constructed from a 6061 T6 aluminum billet. A waterjet cutting process precisely defined the two-dimensional geometry of the tray. Subsequently, the pivot and mounting holes were machined using a milling machine for optimal precision and alignment.
