This is a household meat grinder product designed for office workers. In view of the trouble of how office workers cook their own food in the fast-paced city life, we have designed this "meat mince assistant". Meat grinder is still a niche product at present. After investigation, we found that the main users of meat grinder on the market are housewives, because they have the demand for children to make minced meat. However, we think that urban office workers are also potential users of meat grinder-many of them have their own cooking habits, and they hope to complete the production of minced meat and diced meat faster and more conveniently; we also found that the structure of some competing products on the market has been relatively perfect, but there are also shortcomings such as not fashionable appearance and unfriendly operation experience. The highlight of our design is that our meat grinder can be used for charging without dragging a long wire at a time. In addition, we have also simplified the design of the cutting tool of the meat grinder. We hope that through our design, we can provide office workers with a simpler, more efficient and pleasant cooking experience.
