Car Jack Design - for Tire Emblem rotation only
Ever wonder how they get all four hub caps facing the right direction at car shows?
A: They jack up each corner of the car individually, upright the logo, and gently set the vehicle back down.
If it takes 30-60 seconds per side of the vehicle, that means they’re spending roughly 2400 minutes uprighting the logos on hub caps. That’s 40 hours to do all the cars at one show, or an entire workweek!
Hence, our solution that lowers this time by 90%.
The Solution
The idea is to use a four bar linkage system to prop one tire up at a time. The jack enables the wheels to be rotated easily with one hand. Quickly and safely.
The design consists of two posts that slide in on either side of the tires’ rubber, they are connected with a linkage and a handle. That reduces the weight of that car by a factor of 10.
Each post has independently-rotating sections, one contacting the tire and the other contacting the ground/floor. This allows the jack to slide under the tire while maintaining freedom of rotation.
