Help me think of a gizmo? What do I want to invent?

Funnel-shaped key, put the outside of the funnel.

1. I want to invent a smart paper that can reflect what you think on paper without writing, so that people who can't speak can easily write letters and mail them to distant friends!

2. I want to invent paper that can make sounds, no matter what I draw on the paper, it can make the sound of the objects I draw, such as drawing a puppy will make a "woo" sound; Drawing a train makes a "whine" sound......In addition, if you do not sit well when writing on this kind of paper, the paper will send a warning, which is helpful for children to maintain their eyesight.

3. I want to invent an environmentally friendly paper made from waste and discarded garbage. Because today's paper is made from trees, a 20-year-old tree can only make 3,000 sheets of A4 paper. Twenty years of cultivation in exchange for 3,000 pieces of paper is too expensive, too costly, and a waste of resources.

We call on everyone to save paper and contribute to environmental protection.

Hello classmates, if the problem has been solved, remember that yours is an affirmation of me

Dear, the new year begins, I wish good things one after another 3, the mood is like spring in 4 seasons, life is 5 colors and 6 colors, 7 is colorful, occasionally 8 points of small wealth, and troubles are thrown out of the 9 clouds!

The things I want to invent are: smart trash cans, smart fitness equipment, smart home systems, smart translation pens, smart medical devices.

1. Intelligent garbage bin.

With the improvement of people's living standards, the amount of garbage generated is also increasing. The smart trash can detect the amount of garbage in the trash can through sensors and automatically sort the garbage. It can also connect to the internet via Wi-Fi and tell you which garbage needs to be disposed of and which needs to be disposed of.

2. Smart fitness equipment.

A lot of people love to exercise, but it's hard to stick to it. Smart fitness devices can detect your exercise status through sensors and develop a personalized fitness plan based on your physical condition and fitness goals. It can also record your exercise data to help you analyze and improve your exercise results.

3. Smart home system.

Smart home systems can connect to the internet via Wi-Fi, allowing you to remotely control lights, appliances, security monitoring, and other devices in your home from your phone or tablet. It can also automatically adjust indoor temperature, humidity and other environmental parameters according to your living habits and schedule, making your life more comfortable and convenient.

4. Intelligent translation pen.

Smart translation pens can translate one language into another through speech recognition and machine translation technology. It can help you quickly solve the language barrier in situations such as travel, business, and study, so that you can communicate more smoothly and freely.

5. Intelligent medical equipment.

Smart medical devices can detect your physical condition through sensors and automatically record and analyze your health data. It can remind you to take your medications on time, have regular check-ups, and exercise to help you stay healthy and prevent disease.

Here's an example of how I write a gizmo.

I've invented an extraordinary pair of shoes that are much more advanced than ordinary sneakers, and you're guaranteed to be amazed and want to do so.

These shoes look no different from ordinary sneakers. But if you look closely, there are three colored buttons on the side of the shoe: red, yellow, and blue, and they have different functions, so let me tell you them one by one.

The red button is used to adjust the temperature. It can be adjusted to 30 degrees Celsius, so that people who wear shoes do not need to add socks to reduce leakage and vertical socks can adapt to every season. When it's cold, it automatically heats up so that your feet are no longer cold. When the weather is hot, it automatically cools so that you don't feel stuffy.

The yellow button is used to adjust the size of the shoe. Every mother is most worried about the growth of her child's feet. The shoes that have just been bought, and in less than a month, the child's feet have grown and the shoes cannot be worn.

A good pair of shoes is about to be thrown away, what a waste! Wearing this kind of shoes, you can press the yellow button to adjust the size of Qingshi shoes, just enough to wear, so that every mother no longer has to worry about the problem that children can't wear small shoes.

The blue button is to pick the color. Everyone likes to wear shoes of all colors, but it's impossible to buy them in every color! With these shoes, you can wear whatever color you want!

And these shoes can also match the color of the shoes according to your clothing! Do you like these shoes? If you like it, don't worry, I'll invent it for you to wear!

Today, I'm idle at home, bored, so I use my brain, make a small invention, and I really invent a little thing.

This little object I invented can measure which of the two objects is heavier. That's why I call it "Little Scale".

Want to know how to make a "small scale"?

In fact, making a "small balance" is very simple, first of all, to prepare the materials, you need to use a ruler, adhesive tape, something that can be fixed in a cylinder (for example: a glasses case), an eraser that can be rolled (cylinder). Then, use tape to gently fix the ruler to the box (not so fast), and finally, place the two objects to be measured on both ends of the ruler, and put the eraser in the middle, which side of the eraser rolls and which side is heavy.

How about it, it's easy! I will invent better things later.

Very simple little inventions, I can learn as soon as I learn.
