My little invention excellent composition 1 If I were an inventor, I would invent a crutch that can help the elderly. I named it "universal crutch". The old man is inconvenient to move. If he falls down carelessly, his bones may be broken. Therefore, I want to invent the "universal stick", hoping to benefit the elderly.
The universal walking stick looks like an ordinary walking stick. There is a small hole at the top of the cane. As soon as the chip in the hole is received at the command, the cane will obey the command. Out of concern for the elderly who can't talk, there are two kinds of universal sticks, one is "smart stick"; One is the "hidden energy rod". The hidden energy rod has many advantages. If gangsters kidnap an old man, the old man can make the hidden energy bar invisible, give orders in his head, and the hidden energy bar can call the police. The intelligent staff does not have the function of "giving orders without talking", but the invisible can see the intelligent staff, which is more convenient for the visually impaired. The wand also has a special help-seeking function. If a fire breaks out suddenly, it can be turned into a wet towel immediately, so that people will not suffocate.
The universal wand has many functions. I hope the elderly can feel its convenience. In fact, I want to invent the universal wand because of my elderly grandmother, because I don't want to go to the remedial class after school and take care of me. Grandma is old, unable to move, and her eyesight is declining. For her sake, I resolutely decided to invent the "universal wand", hoping that grandma would be safer and have a good old age.
Today, one year later, I stand on the podium and accept the award from the Association for the Aged. The invention of the universal wand swept the world. ...
My little invention excellent composition 2 Recently, the environment in the city is getting worse and worse, and garbage can be seen everywhere. In order to protect the environment, I used more than 1000 materials and racked my brains to finally invent an environmental protection robot.
My robot is called a sweeper. Its functions are all about environmental protection. Although it is only 130 cm high, it has numerous functions. If it sees someone throwing rubbish, it will go forward to educate the litterer. If it sees garbage, it will quickly judge whether the garbage can be recycled. If it is recyclable, it will turn the garbage into new ones and send them back to the store. If it is not recyclable, just dispose of the garbage. The most amazing thing is that if it meets someone who throws garbage to destroy the environment and doesn't listen to advice, it will hit someone, beat him to the ground, and finally make him recite 1000 times "environmental protection instructions". Maybe you will say: Why does your robot only know how to educate others and have no other skills? That's true. If it sees someone bending over to pick up garbage, it will take the initiative to award an environmental protection award to this person who cares for the environment and send him an "Environmental Protection Handbook" to keep him in a good habit of caring for the environment.
I think, the world is so big, how can only one sweeper be enough? So, I cloned many small cleaners. I also applied for an invention patent, and environmental protection companies and 10 primary and secondary schools all over the world snapped up my products. Soon, my little invention was robbed.
I will certainly invent more things to benefit the country and the people in the future.
My invention excellent composition 3 This morning, I did my homework at home and made some mistakes. I picked up the eraser and wiped it, leaving a lot of dirty things on my exercise book at once. What should I do with these crumbs? So I thought of inventing a little invention to deal with rubber crumbs.
But what kind of things should be made to deal with these debris? I thought and thought at my desk, but I still couldn't remember. I paced back and forth in the room, thinking about this problem. At this moment, I saw a broom and dustpan in the corner. They can clean things on the ground, and I can make a "clean eraser" like them.
How? I've been thinking about it, and suddenly, I had a brainwave and came up with a good idea. My idea is to add a broken brush to one end of the eraser, so that there will be no rubber crumbs after wiping with the brush.
Production has begun. I first dug a hole at one end of the rubber, neither deep nor shallow. Next, put the brush in the hole and stick it with glue. If you are still afraid of cracks in the eraser, glue it with transparent glue for several times, so that you can make a small, convenient and practical clean eraser. Dry it and you can "put it into use"
A clean eraser can erase type without leaving rubber foam. This is killing two birds with one stone.
How's it going? Is the clean eraser I invented not good? It seems that as long as we are willing to use our brains and be brave in practice, each of us will create something.
Once, my family went to Mount Putuo for a trip. When we arrived in Ningbo, I found several small windmills spinning on the top of telephone poles beside the expressway. I asked my mother curiously: Why is there a small windmill turning on the telephone pole? My mother told me that the worker's uncle used wind power to generate electricity. At that time, I had a little knowledge, and later I learned about air and wind in extracurricular books: wind can make sailboats sail on the sea; Turn the windmill and divert water to irrigate farmland. I also know that many advanced countries in the world use wind power to generate electricity, save resources and protect the environment. So, I think if I can invent a car with sails, then this car can go forward by the wind, and this car will never need to refuel and will never pollute the air with carbon dioxide.
With the help of my father, I first found cardboard to make a big windmill, then fixed the windmill on one section of the stick with iron wire, and finally fixed the other end of the stick on the toy car. I came to the open space of the community with my works. Just when a gust of wind blew, the windmill turned very fast and the car drove slowly forward. Haha, my little invention, the environmental protection windmill, is finished. Dad told me that we should try our best to store the wind for use when there is no wind.
I believe that in the near future, there will be a car with sails on the street. Children, you must remember that it was invented by a child named Pan.
This afternoon, I found that my nails were very long, so I decided to cut them. This is the first time I cut my nails myself. Holding a nail clipper in my hand, I carefully began to cut my nails. But the cut nails fell everywhere, on the ground, on the table and on the chair. I find it not difficult to cut my nails, but it is very troublesome to tidy them up after cutting.
Is there a nail clipper that can collect nails while cutting them? Just like the pencil sharpener we use to roll pencils, we can collect pencil scraps in containers while rolling pencils.
Considering that nails will fall off under the action of gravity, I thought about the materials that can be used at home and decided to tie a small plastic bag under the nail clippers to collect nails in time. The first nail clipper I invented was successfully made, and my father decided to try it first. But my father's nails are harder than mine. When I cut them with nail clippers, my nails jumped in all directions, up, down, left and right, but they didn't fall into the bag immediately.
It seems that nail clippers that can collect nails need not only a container that can collect nails in time, but also a protective cover that can stop nails from jumping, and it should be transparent and not hinder people's sight of cutting nails. The materials available at home are too limited, and I'm still thinking.
After class, the blackboard was covered with a bunch of formulas. It seems that the blackboard cleaner will have to work hard again.
Every time you clean the blackboard, either a short person can't clean the top of the blackboard, or someone who can clean the chalk dust on the top is covered with chalk dust on his shoulders. What should I do? At this time, I set my eyes on the broom. Have an idea! I unscrewed the pole on the broom, and then asked someone to borrow a universal glue to stick the broom pole and the blackboard eraser together, thus becoming an extended version of the blackboard eraser.
My little invention has been praised by most people, and now short people can wipe chalk; And tall people can stand in the distance and wipe; With the extended version of the blackboard eraser, cleaning the blackboard is more interesting!
Unfortunately, the good times did not last long. Some people reported that it was easy and effortless to lengthen the top of the blackboard. Wipe your ass with a heavy stick when you can. After listening to this, I will immediately invent a faster blackboard eraser.
Finally, I invented a folding blackboard eraser. Lift the pole when it is high, and put it in when it is low. In fact, the folding rod is just a telescopic pointer, and then stick it on.
Because a small blackboard eraser and a small invention have brought us convenience.
My little invention excellent composition 7 Students, have you ever had such an experience: as soon as you come home from school, you will be busy with your homework until eleven or twelve o'clock in the evening. Especially in exams, time is tighter and people are more tired. But with this machine, everything will change.
My machine can change its size at will, from a house to a speck of dust. You can wear it on your hand. It is shaped like a watch and can tell the time. People who don't know think it is a real watch. But there are two buttons on the left and right sides of the screen to see the time. One is red and the other is green. The red one is the tray for homework. As long as you put your homework in, the time screen will stop working. At this time, you just need to look at the screen and think about the answers to your homework in your head, and this machine will write what you think into your homework. Quite time-saving. Some people will ask, what should you do if you think the wrong answer? Don't worry. When you enter what you think, your answers will be printed in pencil.
This machine will remind you whether it needs to be replaced. If so, you have to choose the multiple-choice question number and then change the answer. The green button will help you check after you change your answer. Check the mistakes and remind you to correct them.
After talking for a long time, maybe you will ask, what is the name of this machine? I'll tell you it's called-"children eat lollipops"!
