Different solutions for various zipper problems

Different solutions for various zipper problems Clothes zippers, after prolonged use, become difficult to zip or unzip due to wear and tear. Smart solutions for fixing zippers: I. Inability to zip up The main reason a zipper cannot be zipped up is that the gap between the upper and lower zipper teeth has widened, or the width of the zipper slider has increased. Gently squeeze the zipper teeth together using pliers, either vertically or horizontally. Be careful not to apply excessive force to avoid damaging the zipper slider! After repair, apply a little wax to the zipper to make it smoother in the future. If the zipper breaks after several attempts at fixing it with pliers, it's time to consider replacing the zipper slider.

The zipper in life

This article explores the patent landscape surrounding zippers, a common household item. You might assume zippers were initially designed for their current applications, but that wasn't the case. As the saying goes, where there's demand, there's a market; and innovation wins the market. Take zippers, for example. Before their invention, connecting two edges typically involved: (1) Buttons: Chinese button knots are still practical, and some clothing still uses them. (2) Laces: Iconic laces and bows. (3) Hook and Loop Fasteners: Unfortunately, I couldn't find an image; imagine a hook and loop working together. So, what would these methods look like on boots, especially the tall boots popular when zippers were in their infancy? Imagine replacing the zippers in the image above with buttons. Considering the less refined and durable buttons of that era, a pair of tall boots might have 20 or more buttons. Putting them on or taking them off might take 30 minutes each (for those with slow hands or less dexterity)... This is the environment in which zippers developed. Research reveals multiple claims regarding the origin (inventor) of the zipper. However, the earliest zipper-related patent I could find is: Those with mechanical knowledge might recognize the structural features of the diagram. However, the key point is the patent application date: August 27, 1914 – quite early! The second question is: how many zipper-related patents exist today? Using Baitian's patent search engine with the keyword "zipper", I found: Disregarding whether all patents relate to zipper structures (some might cover manufacturing processes), the image shows 5159 authorized and valid patents related to zippers. What does this mean? If you want to start a zipper manufacturing, business, or sales company, you must ensure your product's structure is either existing technology or entirely innovative, exceeding existing technology and patents. Otherwise, you risk receiving a notice of patent infringement (though the likelihood is low, the risk exists). I lack the resources to examine all 5000+ valid patents; those interested can explore further. This search is limited to domestic patents and uses the simple keyword "zipper." Zippers are also called "zipper locks," but "zipper" is more common. Internationally, even the Japanese term, when translated, isn't "zipper" but "clamp," which is quite puzzling. A complete search would require considering broader concepts like "sliding fasteners" and "tightening devices." This might yield a more comprehensive result. Please point out any omissions. This and future content aim to promote and popularize patents. Feel free to discuss further if you're interested. Any similarities are purely coincidental.
