20 15 ten most boring inventions

1. Combined plough gun, patent number: 35600, published in 1862. The American inventor claimed that the utility of this invention was beyond doubt, especially in the border areas where fierce conflicts or guerrilla warfare occurred. When a conflict occurs, it is not delayed to plow the land with bullets as big as glass balls or grape beads. The plowshare is used to anchor the machine to prevent recoil, and the manual operating lever is used to adjust the direction. Some people are puzzled that quarrelsome archers are not equipped with such things. 2. Weight wake-up device, patent number: 256265, published in 1882. People who sleep like pigs often can't wake the alarm clock. Why not put a box of heavy objects on the snorer's head? With the help of the mechanical principle of clocks and watches, this wake-up device makes heavy objects "hit" on the sleeper's head until it wakes up. The inventor promised that a light blow when a heavy object falls is enough to wake a sleeping person, but it won't make him feel pain. However, for the sleepy, as long as a thick cushion is placed on the top of the head, all the problems will be solved. 3. Eagle Power Ball, patent number: 863087, published in 1887. Catch an eagle or vulture first. Then tie the eagle to the arc of the balloon. The eagle's beak is facing the predetermined direction. Then sit still, relax, eat and watch movies while flying. The person who came up with this idea is a little talented, but the disadvantage is also obvious-it will attract protests from animal lovers. In fact, the key problem is that it is difficult for eagles to catch prey and carrion to cooperate with us. This is also well known, so it cannot provide controllable or clear driving force. What should they do if they peck a hole in the balloon? Fourthly, the glass coffin, patent number: 748284, published in 1903. It is difficult to find a suitable memorial for the deceased lover. How about storing the body in a glass device for a long time? Heilkay J Kakowski, an American from new york, is stronger than the average family member of the deceased. Otherwise, he wouldn't have concocted such an orderly way to dispose of the remains. Fifthly, beard protection paper, patent number: UK/KOOC-0/9/KOOC-0/27/KOOC-0//KOOC-0/9,/KOOC-0/9/KOOC-0/2 years. Damn hair is always in the way, either hot or wet, and there is always the risk of infection. In order to prevent the last problem from happening, Fritz Bodis applied for a British patent that he would never get his beard wet when drinking. This thing he made is very simple, that is, a protective sterilized cardboard that can be stacked on the mouth of any kind of wine glass. Of course, the cardboard will get wet, leaving the drinker's face covered with confetti. Sixth, the water-filled bra, patent number: US 4734078, 1988 is published. The most famous inventions of the 20th century-World War I and World War II, people put a lot of effort into them. Many people seem to have created killing machines directly with their crazy imagination, but they have been at their wits' end for decades. It was not until the 1980s that it returned to normal, but a useless thing was invented-a magic bra that absolutely met the requirements of the water world. James Morrow, an American inventor, explained that a bra that holds the breasts with water will provide better buoyancy, so that the two breasts can be held separately. Anyone who is fashionable can also use transparent styles. But few users, even Madonna, passed it on to others. Seventh, hood muffler, patent number: 48342 12, 1989 released. You really want to shout after reading this invention, but who will listen to you? Maura and Frank Figovan from Beaumont, California, invented this kind of cover tube, which allows buyers to scream without disturbing others in order to vent their grievances. In this very basic device, there is a layer of sound-absorbing foam inside the flat-bottomed muffler. The cleverness of this thing lies in the built-in microphone, and the display interface will flash when there is sound. Users will get visual feedback immediately and know the intensity of sound. Do you know if it's something else?
