Inventions related to zippers

The zipper is still widely popular today, which has a lot to do with the discovery of new uses for it. In 1893, a Chicago engineer named Judson obtained the first patent for a "sliding locking device", which was the "zipper." He applied this "zipper" to high boots without success. The Swede Sandback improved the crude "zipper" in 1913, turning it into a reliable commodity. In 1926, American novelist Franck named this device the zipper. A clothing store owner used zippers on wallets and later on navy uniforms. During World War I, the U.S. Army first ordered large quantities of zippers to make clothing for soldiers. It was introduced to the people after the war. Peter's company also found success using zippers for sportswear.

The patent for ordinary locking devices expired in 1931. After this, people thought of more uses for zippers. For example, one company made tens of thousands of pairs of zippered boots for sheep with leg disease, an Austrian surgeon sewed a zipper into a man's stomach, zippers were used in fishing nets and zippers in On the seedling shed. The life cycle of a zipper continues as new uses are constantly discovered, with increasing benefits. In this diverse use, various new zippers are constantly produced, forming a zipper product series. Without the discovery of new uses, zipper products would not exist today.

It can be seen that the discovery of new uses can lead to inventions and new products, and imperfect inventions can be perfected and applied to achieve success. In a sense, the discovery of a use is itself an invention.
