Abstract
Oniion, also known as spring onion, is a common vegetable on people's table. It is rich in protein, sugar, crude fiber, vitamins, calcium, phosphorus, iron and other minerals. It has the effect of lowering pressure and lipid, helping digestion, sterilization, preventing cancer, and delaying aging. Because of its rich nutrition and fragrant taste, Onions are deeply loved by the masses, whether it is luxury banquets or home snacks, often see Onions appear on the table. However, because the onion has a special odor, the volatile odor tears to the operator.
Therefore, it is very necessary to design a tool to avoid volatile gas and tears when cutting Onions, which has certain practicality and social life value! This paper presents a design of a household multifunctional cutting onion cutter. The design takes into account the shape and texture of the onion, as well as the needs and habits of the user, using a combination of mechanical design, materials science and ergonomics designed to provide an efficient, convenient and comfortable tool for cutting onions. The tool has a variety of functions, which can meet the needs of users in different situations, such as chopping, slicing, cutting strips, etc. In addition, the design also focuses on the ease of use and safety of the tool, equipped with an easy to hold handle and sharp blade, while ergonomic principles, so that users can operate more easily.
