Tennis ball lighter, flexibility is very good, but picking is a tedious job. Therefore, in order to reduce the trouble, the researchers invented a tennis ball machine. However, the traditional ball machine can act as a table tennis player in athletics "assistant" and not for other purposes. And Yao Chen and other students invention "multiplayer fitness and entertainment machine", to achieve the traditional "ball machine" in Makeovers become a restricted free from venues and crowd innovative sports equipment. This is a new type of instrument is how these students become attached to it?
2012, studied at the School of Mechanical and Electrical Engineering, Jiangxi University of Technology in Mechanical Engineering and Automation of Yao Chen, Chen Yuntao and other five students to prepare for college students across the province that year Mechanical Design and Innovation Competition. Turning to the original intention of the invention, Yao Chen told reporters after the game theme set down, he and his teammates are in the direction of the idea of ??work every day. Happen one day, he went to see the museum's table tennis ball machine automatically, sudden an idea in mind: Can you design a pinball machine that it can not only adapt to the crowd of different ages, but also in different places to use it? So he created a new kind of ball machine design ideas. When we listened to him this idea, hit it off.

After six months the efforts by the national patent
From the beginning of 2012, Yao Chen, who every day except on extra free time were spent in the laboratory.
Chen Yuntao told reporters, after more than two months of verification, the transmitter is not completely taken the final gear-driven design, to achieve a continuous rotation of the motor does not stop, do not reverse the situation intermittent tee.
May 2012, after nearly six months of team effort, a new "multiplayer fitness entertainment machine" was finally successful design. They participate in the province's first mechanical innovative design competition on the college won the second prize. September 28, 2012, they were formally submitted to the State Intellectual Property Office "multiplayer fitness and entertainment machine" patent application. March 13 this year, their inventions formally authorized the State Intellectual Property Office of the announcement and utility model patents.
Yao Chen said that "more than fitness and entertainment machine" total cost of about 2,000 yuan.
Determined to invent more innovative works
According to reports, " people fitness and entertainment machine" user base can be fixed after the single play mode, use the up and down adjustment mechanism to adjust the height of the ball by a transmitter port is issued, players can hit multiple angles training . In addition, " people fitness and entertainment machine" people can play with the adjustment mechanism so that rotation of the entertainment machine , depending on the rotational speed set different populations , randomly distributed in four balls emitting port , the player may exercise ball race .
This work has been with the school robotics professor Xu Guang -hong, director of mechanical innovation design center is highly recognized , she believes that this is a very good innovative sports equipment , hoping "multiplayer fitness and entertainment machine" into the market as early as possible and get big scale promotion .
" Design is still a long road , we hope to design more innovative work ." After obtaining the national utility model patents , coming towards society Yao Chen et al shy to say their dream, they want to set up a working team room , determined by the easiest and most economical way to design more innovative works .
