A while ago I referred to the problem of fat kids and see-saws. Calling out problems you see in the world is easy, but coming up with solutions is difficult. I have designed a new see-saw that makes them accessible to all children, despite their weight.
In a simple sense, a see-saw is simply a lever with a pivot in the middle. The balance of the see-saw is determined not only by the weight of the objects resting on it, but also by their relative positions from the pivot. Therefore, my new design offers additional flexibility by having multiple seats in varying positions along the see-saw, countering any difference in weight that might occur.
But, why stop there? For even more flexibly, I could create a see-saw with an adjustable seat. The seat could be slid into the correct position, then locked into place for a finely tuned balance.
One of the most important parts of designing a revolutionary new product is finding flaws before they become an issue. Who wants to spend time adjusting a seat to play on a see-saw for only a few minutes? That is why the final design would include an automatic weight adjustment system, eliminating the need for differing seat placements. When the see-saw is turned on, the system would calculate the weights on both sides, then pump water appropriately into the two sides in order to create a balance automatically. Plus, it would be environmentally friendly since the motion of the kids playing on the see-saw could be harvested and stored to power the pump.
In the future, playgrounds will have automatically adjusting see-saws for the maximum see-saw experience. You heard it here first. But wait, kids don’t play on playgrounds anymore.
