For example, invention is not far away from us.

Invention is not far away. Modern science and technology change with each passing day, and new inventions and innovations are born every day. For example, smart phones, drones and bicycles are all inventions of today's era. We can see from [4] that there are many innovative products and design schemes in life, which greatly improve our quality of life.

In addition, there are many meaningful inventions not only in the field of science and technology, but also in other fields. For example, for academic research, abbreviations such as "for example" or "namely" are often used in academic papers to express examples and further explanations. [2] As far as the legal field is concerned, patent law is closely related to invention and creation. According to [3], although the books and materials provided by universities are not the conditions for students to make inventions, inventions related to their majors still belong to the category of service inventions.

Therefore, the invention is not far away, and there are many cases worthy of our attention and study in our life around us.
