[Comprehensive] Harbin Business University, more than 2,000 students "creativity big bang" invention sedative anti-mist mask double chain rolling parking spaces

At 12 o'clock on December 8th, the sixth “May 4th” science and technology cultural festival held by Harbin University of Commerce was held. In the “Challenge Cup” competition and the demonstration of student scientific and technological innovation, more than 2,000 students in school carried more than 300 new products independently developed. The group debuted, among them, Yuet-Shen-Sheng masks and double-chain rolling parking spaces attracted the attention of the audience.

During the event, students of the Harbin Institute of Pharmacy presented a number of practical and innovative products related to Chinese herbal medicine. A mask that combines the functions of anti-mite, sterilization, odor, and nerve-stimulating has attracted a lot of attention. According to the research and development team leader and Pu Kaijuan, a pharmaceutical engineering sophomore at the Pharmaceutical Institute, this mask added sterilizing, deodorizing, sedative, and refreshing effects to the flood prevention.

“This device is called a 'dual-chain rolling parking space'. It looks and acts like a Ferris wheel. It uses double chains to drive parking spaces in a space-rotating manner. It uses space height to achieve three-dimensional parking. In early May we did an experiment. In the original location where only three vehicles could be parked, we could use our device to stop 10 vehicles.” Li Bowen, a student at Harbin Institute of Light Industry and Technology, told the reporter of the Life News: “We designed two-way access for vehicles, saving space. At the same time, it can also eliminate the problem of vehicle scratching during reversing and parking."
