For example, in life, especially on holidays, we get together, chat and eat food such as melon seeds and dried fruits. Eating melon seeds is a common daily behavior here. However, this simple, habitual and common life behavior will also produce new ideas. Someone invented the melon seed biting device. This small object seems to have a very simple structure, but its principle is outstanding and easy to use, which eliminates many negative effects brought by people eating melon seeds (introduced by the Central Science and Education Channel).

Therefore, careful observation and analysis of things around you will sprout many novel ideas. It takes brains and observation.

For example, traveling with friends in the wild and getting lost. Using the needle and thread in the sewing kit you carry with you, making a simple compass on the spot can help you get out of trouble. Isn't that a good idea?
