But in fact, almost everyone can invent. It’s just that they do not recognize that their idea could be the start of an invention. The inventor of the dishwasher, Josephine Cochrane, loved to give dinner parties. But she found it took too long to wash her dishes by hand and too many of them broke. She decided that a machine could do the job faster and with fewer mistakes. So, in 1886, she set out to make one for herself. Like Cochrane’s, most inventions are created to solve a problem. So, the first and most important step is to find the problem. You can start by looking at what is wrong with things you use now. You can ask grandparents or neighbours if they remember ever saying: “I wish someone would invent something for…” Or you can look at people in different areas, such as on the street, or at school. Then you might notice situations or things in need of improvement. The next step is to think about possible solutions. An invention is a new way of solving a problem. So think of many, varied, and unusual ways. You can often e up with a solution for a problem by looking at it from a different angle (角度) or thinking about it in a new way. For example, instead of thinking of shoes as protecting your feet from the ground, think of using something to protect the ground from your feet. And if one solution doesn’t work, can it be put to other uses? That was how yellow postit notes(N次貼) came about a “failed” adhesive (粘合劑) experiment proved a weak adhesive had good uses too!After all, most inventions are not brand new (全新). They do not e out of nowhere, but e out of things or ideas that already exist. And the hardest part of inventing, even for a lot of inventors, is ing up with a problem and finding a solution. Once you have an idea, you can always get help building your invention. 44. The main idea of this story is _______.
