World’s Biggest Zipper Maker Is Developing a Self-Propelled Zipper

YKK, the world’s largest zipper maker, has unveiled a prototype self-propelled zipper that uses a motorized worm gear to zip itself closed at the push of a button. It currently relies on a wired remote and external power, and can zip spans up to 16 feet in under a minute. Although some recent zipper innovations, such as Under Armour’s one-handed MagZip upgrade, are designed to improve accessibility and make zippers easier to use for those with limited mobility, YKK envisions more industrial use cases for its prototype. As demonstrated in a video recently shared on the company’s YouTube channel, the self-propelled zipper is seen connecting a pair of 16-foot-tall membranes in about 40 seconds. Zipping them together manually would require the use of a ladder or other machinery.

In another video, the prototype is used to quickly connect a pair of 13-foot-wide temporary shelters standing over eight feet tall, taking about 50 seconds to progress from one side to the other. […] In addition to miniaturizing the tech and adding a battery, YKK would also need to develop some safety mechanisms before its self-propelled zipper could ever reach consumers’ clothing, ensuring there’s nothing that might get stuck.
