The world’s biggest zipper maker made a huge self-propelled zipper

Japan’s YKK, the world’s largest zipper manufacturer (go ahead, grab the nearest zipper, it probably says YKK on the pull), has announced a prototype self-propelled zipper with a built-in motor and gear mechanism it can use to zip itself up at the push of a button on a wired remote.

The days of being embarrassed when you forget to zip up could soon be behind us, if it’s ever miniaturized from its current form, which is several inches long and a lot chunkier than the zipper pulls currently used on clothing.

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.

The prototype uses a spinning worm gear that winds its way through the teeth on either side and pulls the zipper along behind it. In the videos, a power cable is seen attached to the prototype as it self-zips. 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.
