With the rapid development of information technology, data information has become very important for both enterprises and individuals. If important data information leaks out, a new technology, invention or decision will soon become worthless; the protection of information data has become more and more important for the success of enterprises, units and individuals factor. The shredder can realize the fast processing of confidential documents, and plays an important role in protecting data file information [2]. With the development of e-commerce, the improvement of people's living standards and the enhancement of the awareness of confidentiality, shredders have been recognized by more and more government agencies, enterprises and institutions and individuals. According to the statistics of the National Bureau of Statistics, shredders have developed rapidly in the domestic market at an annual rate of 20% to 25%, and are showing an accelerating trend [3]. Therefore, the development of shredders in the domestic market is promising, but for a long time, the domestic shredder market has been monopolized by a few well-known enterprises, the price is too expensive, and it is mainly aimed at enterprises and corporate users. 

However, in countries such as Europe, America and Japan, home users account for a large proportion. With the increasing awareness of the Chinese people's secrecy, China's shredder market will also be tilted towards household users. The current shredders on the market are mainly divided into two categories: one is high-end shredders, with complete functions, easy operation and safe use, but the price is too expensive to be suitable for home users; the other is low-grade shredders The paper machine is cheap, requires manual operation or is not smart enough, and has limited shredding capabilities, which is slightly awkward for home users. Based on the current status and development trend of the shredder in the domestic market, this paper proposes a design scheme for civilian smart shredders suitable for households and individuals, in order to achieve this shredder with complete functions, easy operation, safe use, and good quality. Cheap and other advantages.
