YKK, the world’s leading zipper manufacturer (check your nearest zipper; it likely has YKK stamped on it), has introduced a prototype for a self-propelled zipper equipped with a motor and gearing system that allows it to zip itself closed at the touch of a button via a wired remote.
If miniaturized from its current bulky form, which measures several inches long, these zippers could eliminate the embarrassment of forgetting to zip up completely.
While some recent zipper innovations, such as Under Armour’s one-handed MagZip, focus on improving accessibility for individuals with limited mobility, YKK envisions this prototype being applied in more industrial contexts.
A video shared on YKK’s YouTube channel showcases the self-propelled zipper in action, connecting two 16-foot-tall membranes in approximately 40 seconds—a task that would typically require a ladder or heavy equipment if done manually.
Another demonstration features the zipper quickly linking a pair of temporary shelters that are 13 feet wide and over eight feet tall, completing the task in about 50 seconds.
The prototype operates using a rotating worm gear that engages the teeth on both sides of the zipper, pulling it along behind it. In the footage, a power cable is visible, powering the zipper as it functions autonomously. For this technology to be adapted for consumer clothing, YKK would need to address miniaturization, battery integration, and establish safety features to prevent any potential snags.
