CCTV-10 "I Love Inventions" 20141016 made of steel claws, inventor: Xi Yuejiu.
If you encounter a knife-wielding gangster unexpectedly in your life, how should you protect yourself and escape unscathed? Xi Yuejiu, an inventor from Changchun, Jilin, hopes that his anti-riot arrester can help respond to crises, subdue gangsters, and reduce casualties. The mechanical gripper in cold weapons can capture an enemy from two meters away without hurting him. In 2014, Chinese Channel found this humble farmer inventor and talked with him about his journey in the invention business.
Chinese Channel: When did you become interested in inventions?
Xi Yuejiu: I have had a strong interest in inventions since I was about 8 years old. I still remember that when the adults in the countryside were working in the fields or building houses, I would often make a little noise on the sidelines. I had an idea, how to do this job more effortlessly, and I was often praised by adults. Haha, at that time, I still nicknamed myself "Little Zhuge".
Chinese Channel: What was your first invention?
Xi Yuejiu: It was so early that I really can’t remember. The "Game Fragrance Health Seasoning" that won the national patent certificate was the first one. It applied for authorization in 2008 and in 2012.
Chinese Channel: What do your family members think of your invention? Do you support it?
Xi Yuejiu: At first, my family was very supportive. Later, when I saw that these inventions had not been converted into RMB, everyone changed their attitude and thought that I was not doing my job properly. Later it was not supported.
Chinese Channel: Can you tell us about your original intention and process of inventing the police anti-riot arrester?
Xi Yuejiu: The original intention of the invention probably came when I saw a young policeman on TV news who was stabbed several times while fighting with a knife-wielding gangster and finally died. At that time, I saw his family grieving and crying on TV. The picture in my heart can be described as "heart-breaking" pain, so I vowed at that time: I must invent a "sharp weapon" for catching violent knife-wielding elements! We will no longer let our police officers bleed and die any more, and we will no longer let their families endure the pain of losing their loved ones. That night I stayed up all night to draw up several R&D project plans. As for the process... It can be said that during the time when I was doing research and development, I was a weirdo and a "fool"... When people talked to me, I often asked questions that I didn't answer; when I went home, I often went to the wrong building; my mind was filled with all kinds of things. Inventing, too focused on everything else, a little absent-minded.
Chinese Channel: Among your many inventions, which one is the most satisfying? Why?
Xi Yuejiu: My most satisfying invention project is the patent for a series of police anti-riot arresters. Because police anti-riot arresters should be said to be "stability-maintaining weapons" that play a role in punishing evil and promoting good, and will produce huge social benefits after being widely promoted. Then, the emergence of police anti-riot arresters is like the "airbag" of a car, which may be the last guarantee of people's lives in an emergency. Also, at the beginning of the research and development of the police anti-riot arrester, there were no reference materials in the world. The project establishment, design drawings, sample production, patent application, submission, defense, etc. were all completed by myself without any agency. The product test was successful. At that moment, I was very excited and it felt so difficult.
Chinese Channel: What problems did you encounter during the invention process? What impressed you most?
Xi Yuejiu: I didn’t encounter any big problems with the design drawings during the invention process, because my personality is: I don’t ignore every detail in the initial drawing stage of developing a project. My design philosophy is “products within ten years.” There is no room for improvement”! The problem all lies in the sample manufacturing process. Due to limited conditions, almost every part is made by hand. Slight injuries are a common occurrence for me.
What impressed me most was that when I was making the power system of the police anti-riot arrester, I went to many places that sold springs but they didn’t have what I needed, so I spent a lot of money to customize several of them. I couldn't achieve the effect of my design, and I almost didn't sleep for five days and five nights. In the early morning of the sixth day, I couldn't stand it any longer and fell asleep on a stool. I woke up an hour later and suddenly had a new inspiration, so I started I made the spring myself. Because I was impatient and didn't get enough rest, the wire bounced back and almost blinded my right eye during the making process. I feel a little scared when I think about it now.
Channel Chinese: Did you encounter any theoretical or principle problems during the invention process? How did you solve it?
Xi Yuejiu: It can be said that in the process of invention, we encounter multiple problems every day and solve them every day. You want to ask me how I solve problems. In fact, I have a rather unusual habit: I never leave the product or drawings without solving the problem. I never leave my hand with the products I developed while eating, sleeping or even going to the toilet. Until now, I do it every day. I picked up the sample and looked at it for a long time, researching whether there was any room for improvement and striving for more perfection.
Chinese Channel: What are your future plans?
Xi Yuejiu: My future plan is to realize the transformation of scientific and technological achievements of successfully developed projects while continuing to invent other projects. Since the 18th National Congress of the Communist Party of China, there has been a new year and new atmosphere, and national policies are getting better and better. 2014 is the first year of deepening the reform of the national economic system. Haha, it should also be the first year of my personal life. In the era of the Chinese Dream, I will definitely achieve it. The dream in my heart! Making safe and efficient arresters for the police
After developing some small inventions, Xi Yuejiu turned his attention to police equipment. "That was in 2011. A police friend of mine encountered a gangster while on duty and was stabbed by the gangster during the struggle. At the same time, I often see in the news that police officers are stopping or arresting drunken people. When armed rioters or knife-wielding violent persons make direct physical contact with the opponent, many police officers will be injured and even lose their lives," Xi Yuejiu said. These things made Xi Yuejiu full of emotions, so he came up with the idea of ??making a safe and efficient police catcher.
Putting on work clothes, a mask, and taking out a variety of tools, Xi Yuejiu looked very capable and serious when he entered work. In order to develop the ideal catcher in his mind, he would often work continuously. Work in the room for more than ten hours.
“Although the police steel forks in the past could restrain the enemy, they needed to be used together and close to the wall to be effective. This time, I used nearly a year to use the two-way ratchet principle to make my own I designed, developed and produced a arrester that looks like handcuffs and has a trigger mechanism. I named it a 'police riot arrester'. It is equipped with a telescopic long pole. The surface of the product is made of stainless steel and is coated with titanium. At the same time, technical processing has been done, and it has now been put into mass production," Xi Yuejiu told reporters while picking up a catcher.
The reporter locked the "knife-wielding gangster" two meters away
To verify whether the "police anti-riot arrester" is effective, the reporter and Xi Yuejiu conducted an on-site simulation experiment. The reporter picked up the arrester and "struggled" with Xi Yuejiu, who was disguised as a "knife-wielding gangster." As soon as the reporter put the arrester on the opponent's knife-holding arm, the mechanism was triggered. The cuffs like two crescents locked the opponent's knife-holding hand very quickly, and it only took one day. trick. "Once locked, the more you struggle, the tighter the lock becomes. Moreover, it can also lock the opponent's legs. After locking the legs, you only need to gently pull them apart, and the opponent will fall to the ground and lose the ability to resist. This The catcher is 2.1 meters long and weighs 2.6 kilograms, which can completely defeat the enemy with one move from two meters away. It also has a strong safety function, making it difficult for the opponent to break away," Xi Yuejiu said.
We must continue to develop police equipment
Then Xi Yuejiu showed reporters the appraisal certificate he had just received from the Ministry of Public Security. It turned out that on April 7, his "police anti-riot arrester" The "catcher" passed the inspection of the Special Police Equipment Quality Supervision and Inspection Center of the Ministry of Public Security.
“The device I invented not only prevents police officers from having direct physical contact with each other during riot control and arrests, and greatly reduces police officers’ injuries, but it can also be used to arrest dogs or other animals that hurt people. At the rescue site, I believe it will be vigorously promoted in the future," Xi Yuejiu said. Xi Yuejiu, who now holds nearly ten national patents, is still pursuing his ideal, which is to continue to develop various police equipment. "I hope to develop better and more practical inventions to benefit citizens and maintain public order," Xi Yuejiu said. The "artifact" for anti-riot arrest can defeat the enemy with one move from two meters away - This mechanical gripper was invented by Xi Yuejiu, who was born as a farmer. It can capture the enemy two meters away without hurting him
Being a farmer Xi Yuejiu invented a police riot arresting artifact that can respond to crises, subdue gangsters, and reduce casualties. The mechanical gripper in this cold weapon can capture an enemy two meters away without hurting him.
45-year-old Xi Yuejiu was born in a peasant family in Nong'an County. In order to fulfill his dream of invention, he rented alone in an old residential building near Tiebei 4th Road, Changchun City. When you open the door, you feel like you have entered a small repair department. Parts of various sizes and shapes are piled up in an orderly manner in the living room. There is a row of instruments that look like police forks standing on the wall of the bedroom. These are police forks. Riot arrester.
How is the effect? ??Is it really an artifact? Xi Yuejiu took a catching device and said confidently: "What it pursues is to defeat the enemy with one move from two meters away!"
On April 7, this patent has been recognized by the relevant national departments. After passing the inspection, in addition to being used in public security departments, it can also be widely used in schools, hospitals, banks and other public places with standardized security measures.
“At the beginning of the research and development of the police anti-riot arrester, there were no reference materials in the world. The project establishment, design drawings, sample production, patent application, submission, defense, etc. were all completed by myself without any reference. Agency..." The moment the product test was successful, Xi Yuejiu was particularly excited.
Being a farmer, he had engaged in breeding and driving a car dealership. His personal assets exceeded one million as early as 20 years ago. However, due to an accident in 2010, he only had 500 yuan in his pocket to start a business. Beijing is working hard again. Now, he has more than 20 invention patents, from "remote control door opener", "automatic shoe rack" to the current catcher. It seems that no one is next to anyone else. These have laid a solid foundation for his inventions. Base.
However, the arrester is his most satisfying work. Talking about the original intention of research and development, he said that a few years ago, he saw a young policeman on TV being killed several times while fighting with a knife-wielding gangster. , the TV picture of the family’s grief was really heartbreaking. “I swore at that time that I would invent a sharp weapon to catch knife-wielding violent elements, so that no more police officers would bleed and die...”
Xi Yuejiu said that he is still pursuing his dream, which is to continue to develop various police equipment, hoping to be widely promoted and play a role in punishing evil and promoting good.
