2023 Formula-e Objective

Run as far as possible 

Each team will run their vehicle (one at a time) in an attempt for their vehicle to travel the greatest distance along a course defined by the contest operators.​

Our Concept

Horizontal vehicle with less gear sets

We challenged the conventional way, making horizontal cars because we can use fewer gear transmissions to reduce energy loss. The rubber band will drive the wheel only through one gear set. Throughout the entire process 3D printing method was highly involved for fast iteration.

Achievement

Break record, best-looking & design award

  • We did 4.7 laps in the final, almost double the history record created by the program chair(2.9 laps).

  • We won the best-looking car design award 2023.

My responsibility

Conceptualization, design engineering, making and testing

• Conceptualization: I proposed new concept that uses less gear sets to reduce energy loss, setting the correct direction for our project.
• Design and Engineering Synthesis: I iterated design by analyzing structure and mechanics to improve strength and weight of wheels and bearing structures.
structures.
• 3D Printing and Testing: I specialized in 3D modeling, printing, and hands-on model making, ensuring all parts can be produced and assembled properly.

Stage1

Rough mock-up, LEGO parts

We make the mock-up with lego parts, this the fast and cheap way to test if our assumption of the concept is going to work or not at the very beginning.

Stage2

Stronger material, MDF

The lego part cannot hold too much power from the band, so we laser cut the mdf board to make the stronger version. So, we could study how the band is gonna to perform under higher load.
