The students have obtained the national patent for inventing new schoolbags. What are the highlights of the new schoolbag?

Recently, Pan, a fourth-grade student in Wuxi City, Jiangsu Province, designed a new type of schoolbag with special functions, which won a national patent and will be sold in batches in the future. The schoolbags designed by Pan are very innovative, with many styles, including the usual back-hanging type and the diagonal slung type, which can meet the needs of students. So what kind of schoolbag did he get the national patent? It is not difficult to see from the design of the schoolbag that Pan is usually a well-planned child. He divided his schoolbag into many interlayers and classified all the school supplies that he could use at ordinary times. There are bags in the schoolbag to distinguish all kinds of books, and there are label columns in the inner bag. There are bags for exercise books, stationery bags, water cups and other items. This separate design can clearly distinguish school supplies, and the side cover and label bar are also designed. After the schoolbag is put into the desk, it can also be opened from the side, and the location of the textbook can be clearly known through the label. This kind of schoolbag can avoid the problem that school supplies are mixed together and it is difficult to distinguish. It can also improve children's inductive sorting ability and reduce the inconvenience of carrying things in the desk. A fourth-grade student can invent such a great product, which shows that today's children are still very innovative, which is also inseparable from the usual training of parents and teachers. After receiving this patent, Pan expressed great pleasure and took a group photo with the patent certificate. In recent years, the state has also attached great importance to the cultivation of primary school students' ability to develop and innovate, and issued the National Pilot Demonstration Work Plan for Intellectual Property Education in Primary and Secondary Schools (for Trial Implementation), hoping to make young people form the consciousness of loving innovation, respecting knowledge and protecting intellectual property rights, and promote the improvement of primary and secondary school students' innovative ability. The goal is to build 100 schools nationwide in 2020? Demonstration school of intellectual property education? . And exceeded the target on 20 18. I believe these children will continue to use their imaginations to surprise us.
