Finally, a zipper that zips itself

The cutting edge of zipper technology involves zippers that work remotely. Japanese zipper maker YKK says it has developed a prototype for a self-propelled zipper that zips up with just the push of a button.

These self-propelled zippers aren’t meant for your jeans or jackets, but rather for industrial uses, like tall tents that can’t be zipped up without using a ladder. That’s the mostly likely place you’ve seen YKK’s logo (it has 40% global market share). The company says the tech will save time and be safer than putting workers high up in the air to zip and unzip in hard-to-reach use cases.

YKK conducted experiments with the zippers in February. It says that in one trial, the self-propelled zipper was able to zip up a 16-foot membrane in 40 seconds; in another, it zipped two arched shelter tents together in 50 seconds.

The secret to the tech is a motorized screw that hooks the teeth of the zipper behind it as it moves forward. Video of the prototype shows the zipper and the button pushed to turn it on both connected to a cable, and the zipper itself is encased in a clear, transparent shell.

YKK isn’t releasing the self-propelled zipper yet, but says it will continue to develop the prototype for practical use. If the company can get the tech off the ground, its wide adoption could push tents, temporary shelters, and partition dividers higher than they already go without any human-ladder limitations in the way.
