Final Sled Design

Our final design was tested in field on February 2nd 2015 on IIT campus. This happened to be the day after the 2015 Chicago Blizzard which dropped 21" of snow on chicago. Our design met most of our functional requirements and passed 6 out of 7 rounds of sled dodgeball.

The functional requirements not met:

1)  Our personal cost was not under $75.

Our design was the lightest and one of the fastest. It gave 60% protection to the rider. The rope attachment did not fail and we were able to grab dodgeballs from the front.

 

The design failed at 7 rounds due to the wall breaking from the bottom. The tubes holding the wall also gave up, because they were glued on. Glue has been known not to hold up in extreme stressful conditions. The bottom piece of the sled contained slots for the wall to sit in which is where it eventually failed. Our team was proud of our design regardless of some of the stress failures.

Given less restrictions we could of added plastic brackets on the bottom of the walls that screwed in or just used different material that was stronger to prevent failure.
