The goal of this project was to develop a device to improve the safety of playground seesaws. Seesaws can cause injury or discomfort due to the jarring impact experienced by the user when the seesaw hits the ground because of the other user dismounting the seesaw. To address this issue, we designed, built, and tested a modular shock-absorption system that applies a braking force to seesaw motion, thus limiting seesaw acceleration, and consequently, preventing large impact forces. The device attaches to a variety of seesaw geometries. Testing shows that the device successfully reduces the likelihood of user injury without impeding normal seesaw operation.
