< < stationery / > the seat obtained by Dai Guizhu is patent, but it is difficult to find the next home Reporter Guo Yao's reporter Huang Li
April 22nd, Ji'nan Engineer Dai Guizhu took part in the third China (Shanghai) international technology import and Export Fair ("the rendezvous"). This time, Dai Guizhu has attracted the attention of the award-winning "basin type" seat. Behind the honor, Dai Guizhu has been studying for 28 years, compared to the award, Dai Guizhu is more important, when the seat can be really applied to cars, trains and aircraft?
the venue dynamic: "everyone is competing for the chair I invented, that is, comfortable"
22, Dai Guizhu from the departure of Ji'nan to arrive. The sea. 23, 24, "on the fair" exhibition site, Dai Guizhu's chair attracted much attention. "Everyone is fighting to sit on the chair I invented and sit up to be comfortable!" he said his work on the 24 day, with a pride in his tone. "There are more than 100 people in a day!"
Dai Guizhu, born in the 50s of the last century, had been in the countryside, and he was also a worker in the Ji'nan iron and steel factory, and after he returned to the college entrance examination, he took the exam. He majored in mechanical engineering of Shandong radio and TV University and worked as a senior engineer after entering the Shandong prosthetic and orthopaedic rehabilitation center. The painful experience of a train in 1987 created Dai Guizhu's idea of "sitting still" seat. The biggest drawback of "
" general train seat is that the seat and backrest are fixed and the angle is not suitable for sitting. " He said his original design was designed to slide forward, so that the spine could be adjusted to a more comfortable angle. In 1988, Dai Guizhu formally applied for the national patent to the relevant departments. In January 1994, the invention patent of "sitting on two chairs" was officially authorized by him.
but his pace is more than that. In addition to his daily work, what he thinks is how to make the seat more comfortable. "Once I saw the rocking chair for the elderly, I suddenly got inspiration." One day after 8 years, Dai Guizhu suddenly thought that the chair base would be designed to sink, and it would be more comfortable to sit on. "The general seat is adjusted by the back of the backrest. I designed it downward, with both angles and space." Compared with similar products in the world, Dai Guizhu's invention has obvious advantages.
before and after 2010, Dai Guizhu improved the seat on the basis of this, combined the move and sink, and invented the "basin type" seat. "This design combines the advantages of the first two, and it is more comfortable to sit up." He said that he also made an analysis from mechanics. The reason why people sit there is not tired is the result of the two forces counterbalanced by specific angles.
innovation bewilderment: "Why are billions of designs benefiting no one?"
after 3 designs, Dai Guizhu's confidence in his invention has multiplied. The seat he designed has won many awards, but in Dai Guizhu's mind, the most desirable thing is that the product can really be used for practice.
he said, he had been to Ji'nan, Qingdao, Liaocheng, Zhengzhou and other places, and some trains, bus manufacturers have been in contact, many enterprises have seen the products repercussions, but to the application, there is no following. Some enterprises have said that the new seat design can not be found in the existing national standards, and can not be put into use, while others say there is risk.
"billions of passenger traffic per year, many people take the old seat, too hard! If you can change this new seat, even if you sit in hard seat and economy class, you can also enjoy the treatment of the berth and the first class." He said that the design of billions of people, why did no one dare to use? The country vigorously advocated scientific and technological innovation, the invention of the East and the West have also won the national patent, and did not think that the landing is so difficult. "I am 60 years old, waiting for 28 years, from black hair to white hair. I don't know when to wait."
City Intellectual Property Office: once found an enterprise to negotiate but failed, will continue to help promote
reporter contact the Ji'nan Intellectual Property Office, staff introduction, a invention innovation from theory to practice needs a process, there is a contradiction, that is, the State encourages inventions innovation, What is invented is also faced with the difficult problem of application. Take this seat as an example, such as the train, bus and other supporting seats, its implementation needs a certain standard, to put new inventions into use, can consider the new seat related parameters up to a new standard, this is very difficult, and so on for more than ten years or even decades is possible. However, the staff said they could help promote the new invention through web sites or physical display.
informed sources of the Bureau said that they had previously coordinated some of the seats for the seat, but failed. At that time, it was not easy for enterprises to provide specific parameters and experimental data.
reporter contacted a passenger car production and development enterprise in Ji'nan. The staff thought that the seat designed by Mr. Dai is active, and there may be some unsafe factors in the process of vehicle brakes.
