A Zipper Patent Sat in a Garage for 40 Years. Now It's Real

Bill Freeman, an electrical engineer at Polaroid, patented a three-sided zipper in 1985 that could transform floppy structures into rigid beams. After decades of neglect, researchers at MIT CSAIL finally realized his vision. They developed the Y-Zipper, a 3D-printed fastener that snaps flexible objects into load-bearing structures with a single pull, proving that brilliant ideas often just need time for technology to catch up.
