3. The invention led to a quantum leap in human history. From then on, better and safer airplanes have been invented and long flights have become increasingly convenient and comfortable. Round the world trips have become a reality. Without the Wright brothers, we might still have to spend days, weeks or even months travelling to distant places today.

The Wright brothers have also inspired generations of people to make great achievements in their own chosen fields. China, for example, had to depend on the West for its large passenger aircraft.

How to Invent a Product

1.

It's unnecessary to think of something that no one has ever thought of before. Just ask yourself what exactly you are trying to improve or solve? If you want to build a better dust mop (拖把),how will it be better? What interesting or important part does it have? What could you do differently?

2.

Try coming up with 15 solutions in a minute, no matter how crazy. Or choose one of the solutions and ask how is that like my idea? "How and why does it work?" "When, where and how is it used?" "How is it described?" Let your questions and imagination come up with new ideas or find a different way of looking at a problem

3.

Visit stores that offer products similar to what yours will do and even go as far as to ask store workers for products they might sell with a similar purpose. If you have a name for your product created, search this to find out whether it is already being used.

4.

This is often the longest part of inventing! Thomas Edison's lab tested more than 6,000 different materials for light bulbs before they came up with one that worked. Make the model until it works the way you want. Sometimes you might discover an entirely different idea.

5.

When you think you've got everything ready, it's time to make a working model of your invention --- a prototype. This is what you'll use to show people what it will look like and how it will work. You can use this prototype to show and introduce to the people who might have interest.

A.Research your invention.

B.Brainstorm

C.Ask for advice.

D.Find a problem worth solving.

E.Make your invention to a reality.

F.Build, test, rebuild, repeat.
