Throughout history, inventions have been developed that have profoundly impacted the course of mankind. Movable type, invented by Johann Gutenberg, and the discovery of penicillin are two notable examples.
But don't think your invention ideas have to be earth shattering to be worthwhile. Think about the little things…everyday objects that have made our lives easier? Take the package saver. What would life be like without that small circular piece that keeps the pizza from hitting the top of the box? Patented in 1985 by Carmela Vitale, the package saver will never bring about a new renaissance, but boy are we grateful.
And then there is post-its. 3M could not find a use for its repositionable adhesive until years later, a new 3M product development researcher named Art Fry, frustrated by the way his paper bookmarks would always fall out of his books, gave the product its current form.
