My little invention composition

In daily study, work or life, when it comes to writing, everyone is certainly familiar with it. Writing is an important means to cultivate people's observation, association, imagination, thinking and memory. I believe many friends are very upset about writing. The following is the invention composition I collected for you, for reference only. Let's have a look.

My invention composition 1 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, the car can move forward by the wind, and the car will never need to refuel, and it 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 "environmental windmill" has been completed. 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.

My invention composition 2 At noon on Saturday, my father was taking a nap and my mother went to work. I had nothing to do after finishing my homework, and suddenly I became interested in the bottles and cans of cosmetics on my mother's dresser. I see my mother washing her face every day, first taking water, then applying this cream, and then applying that cream. Layer after layer is troublesome and a waste of time. I think it would be great if I invented a cosmetic and touched it at once.

Let's get started. I'll find an empty bottle, pour some rose oil and white water, then pour some emulsion, smell and spray some perfume, find a toothpick and stir it, and the new product as white as milk will be ready. I can't wait to try my new product.

At this moment, I saw my father sleeping soundly. I walked softly to him and drew on his face without hesitation. Dad's awake. I patted my father's fat belly and said, "Be good, don't move. I will give you beauty. Go to sleep. " Say that finish, dad fell asleep again. I learned from my mother to massage my father's face, and suddenly my father's face was shiny. It is really white and red. Just as I was immersed in the joy of success, I was extremely happy inside. At this time, my mother came back, and I excitedly showed off my new product to my mother. My mother looked at the dresser where the comb stood, looked at me, and then looked at my father's face. I totally understood, and I started to get angry. This is her baby! Thanks to my father's protection, I didn't get beaten.

On the third day, my father's face was covered with red acne. Although the invention failed, I will never lose heart. Didn't Edison do thousands of experiments when he invented the electric light? I think this wish will come true in the near future.

My invention composition 3 Hi, everyone. Presumably, everyone already knows my previous invention-"explosive flying shoes"! I'm all red … but something unusual happened during the winter vacation. Let's listen to me!

Today, the weather is fine and the sky is clear in Wan Li. The teacher of the handicraft class said to us after class: "Ladies and gentlemen, today's homework is: go home and make a small invention and hand it in tomorrow." I listened to it and thought: Oh, what a small invention! It's annoying to come when you know I'm not good at it! ! Suddenly I had a brainwave and thought of a good idea: I can hand in the "explosive flying shoes" and "upgrade"! Do it! When I got home, I immediately ran to my room to find the "explosive flying shoes" and began to "upgrade": first, I added several super-large springs to the "explosive flying shoes"; Then, find a few pieces of stainless steel and stick them with 502 glue; Finally, stick a few gorgeous stickers and you're done! I went down to try running. I wanted to "go with the wind", but I failed! I thought to myself: Why did I fail? After my repeated thinking and careful study, it turned out that the wind was too strong, the wind direction could not be controlled, and it failed! Unwilling, I had a brainwave and thought of a good way: I can add a "wing" to it! After adding wings, I went down and tried to run again, and it worked! I jumped for joy.

The next day, I took my "gizmo" to the handicraft class and gave it to the teacher. The teacher looked at it and said, "Well, Cheng Bolin did the best!" " I listened and thought: Haha, the light of victory shines on my face!

I love my little invention.

People's lives have many inconveniences.

For example, it's very hot in summer, and when I get home, I'm exhausted and sweaty. If I blow it with an ordinary electric fan, it's still the same hot air. It's very cold in winter, there is no air conditioning in the family, and it's very cold at home. ...

Now I have invented an advanced multifunctional electric fan, which is much stronger than ordinary electric fans. Let me tell you what it is used for.

In summer, when I got home and felt very hot, I said to the multifunctional electric fan, "Air conditioning will appear soon!" " "It will spit out five times the air conditioning, not to mention how cool it is.

The temperature is low and the weather is cold in winter. Just say to it, "Give me a warm and gentle wind." It uses a heater to blow the home warm and soft, which is really comfortable!

If there is a strange smell in the house, it will send out a red alarm to remind the owner to open the window and let the smell out.

The multifunctional electric fan consists of magnets, blades and shafts, and is controlled by sound. It has no plug and can be moved at will. Only a small high-energy battery is needed, which can be used for about a week once charged.

Multifunctional electric fans cannot be made in a day or two. It takes a lot of energy, but I will finish it. This is the first invention I have created, and it will definitely bring people laughter.

One day, after I finished my homework, I saw that the stationery in the pencil case was not creative enough, so I wanted to create more creative stationery, so I took out the paper and drew while thinking.

I drew a pen first. I drew two pens, one for summer: there is a small fan on the pen holder, which will rotate as long as the temperature is higher than the specified temperature, and there is an automatic cooling device in the pen holder. The other pen is designed for people with incorrect writing posture: if your posture is incorrect, it will give a voice reminder, and after more than five times, the pen will stop coming out of the water, and if you hold the pen incorrectly, the nib will shrink.

Then I draw an eraser. The four corners of the eraser have different functions. The first corner is pointed, which is specially used to wipe small places. The second corner is curved, which is specially used to wipe a bigger place. White non-toxic and harmless liquid will flow out from the third corner, which can erase the words written by fountain pen. The fourth corner can stick out the dander scraped by the first and second corners, and then absorb and reuse it to achieve the effect of environmental protection. Moreover, the rubber is mainly white and will not appear fancy.

Finally, I drew a ruler, which can draw infinite straight lines and wavy lines. The principle of drawing an infinite straight line is that there is a rectangular hole between the ruler and the slider. First draw a line with the ruler, then press and hold the ruler, move the slider, then press and hold the slider, move the ruler, and draw another line ... This can draw an infinite straight line, and the ruler is easy to clean.

This is my creative stationery!

When I went to the toilet at noon, I suddenly thought of using a rope to control the faucet of my bicycle, which should be very labor-saving. When I came out immediately, I found a rope around the faucet of the bicycle, leaving two leaders holding hands. I tried it. When the left hand rope pulls the faucet, it turns left, and when the right hand pulls the faucet, it turns right. I'm so happy. I'm looking forward to trying my hand on the highway.

When my mother came back from work in the afternoon, I took my mother to ride a bike on the highway-a bike with a control rope. As soon as I got on the bus, I rode forward with my hand on the rope. At this moment, I thought: it's great to ride without bending over! I just thought of it here. Suddenly, the faucet made a 360-degree turn and I almost fell to the ground. I straightened the faucet and continued to ride with the control rope. After not riding far, the car fell down again. I quickly put my hand on the ground. I still haven't given up. I rode a bike for the third time. Just after passing Haitang Avenue, my car fell down again. This time, I'm not as lucky as the previous two times. The car fell down, so did I. I scraped my elbow and shed a little blood. My mother ran over and said, "Wow, you hurt your hand." At this time, I felt a special pain in my hand. I have to push my bike home.

This is the first time I fell off this bike. When I walked home, I thought if I used a hard rope to control it, the faucet wouldn't turn. In the future, I will try to invent.

There are many inventions, tangible and intangible; Visible, invisible; Tangible, intangible. Students, what is your invention? Come and write with me.

My gizmo is tangible and tangible. Its name is "Rabbit Handbag".

The materials needed to make this small bag are cardboard, wool and colored pens. After finding all the materials, I began to do it. First, draw rabbits (not just rabbits, of course) on the selected colored paper board. Such rabbits need to draw two. Then draw two long ears on another piece of card paper, and paint them with beautiful colors, both sides should be painted. Then make two cuboids out of cardboard, stick the two rabbits on the cuboids separately, which is the space for loading things, and then stick the bottom with double-sided tape to avoid leaving small holes to prevent the loaded things from falling. After these are done, draw the rabbit's eyes and mouth with colored strokes, and finally tie the rabbit's head with wool. This beautiful "rabbit handbag" is finished.

With this handbag, waste products and pencils will be put here and hung on the wall to make the home look neat and beautiful.

Anyway, my invention is good! What kind of inventions do you have? Come and talk as soon as possible.

My little invention composition 8 classmates! If you want to ask me what the future pen is like, I will tell you without thinking: "I invented the future pen." It is not only beautiful and generous, but also very practical. If you don't believe me, let's take a look! "

The future pen case I invented is colorful and will change colors according to the seasons. Spring turns green, summer turns red, autumn turns gold, winter turns silvery white, and it is colorful and beautiful under the sunshine! The pen body is slender and delicate, with clear patterns, and there are many small animals and fairy tale characters. Its pencil case is dark green, like a military cap worn by soldiers, very imposing! At night, it will shine brightly. If a rainbow appears in the sky, it will take care of colorful light, which is very beautiful.

This pen is versatile and has three small and exquisite buttons. Press the first button, it will be a pen, press the second button, it will become a pencil, press the third button, it will become an eraser, which is very easy to use. In the past, pens were very inconvenient. Every time I write, the pen always breaks the lead and blackens the book. The pen is still very weak. If it falls, it will break into pieces. Pen ink always drips on the book, making the book full of ink. Appear for a while, don't appear for a while, and the words written are always intermittent and extremely annoying. But the pen I invented can solve these troubles.

There are many wonderful things about this pen. For example, if you make a mistake, it will sound an alarm to remind you. It can also play music. As long as you say the music you want to listen to, it will release beautiful music to eliminate your fatigue. Moreover, the lead in it never needs to be changed or used up, which is particularly time-saving and convenient.

With the rapid development of society, there are more and more high-tech pens, but after listening to my introduction, everyone's interest in the pens I invented must have doubled!

During the summer vacation, I finished my homework and called my friend Lei Jiayin to chat. However, this call lasted for two or three hours and wasted a lot of phone bills. Mom was furious when she knew: "You are not allowed to call Lei Jiayin in the future, and you are not allowed to chat online." . I muttered discontentedly, "If you don't talk, you won't talk. When I learn English at Harvard and get the first place, the computer will be mine. " "That won't do either!" Cried the mother. "Then I'll make my own mobile phone!" "If you have the ability, you can build it!" Mom said contemptuously.

Go ahead. It's hard to say. Well, I went into the refrigerator, huh? Where are the paper cups in the refrigerator? I turned left and right, but I couldn't find it. Did it fly into the sky with wings? Or are you stuck in the swamp and going to hell? Even if it runs away with long legs, there is no paper cup anyway, so it can't beat me. I have 10 yuan's "private money". I used this 10 yuan to buy a pack of paper cups, which can be used not only to make phone calls, but also to hold water for guests at home. It's killing two birds with one stone. I prepared two paper cups, dug out a ball of wool from my mother's closet, punched two holes in them, and connected them with wool, one at Lei Jiayin's house and the other at my house. If Lei Jiayin wants to talk, pluck his hair and cover his mouth with a paper cup. When I aim my ear at the paper cup, I can hear it, which not only saves electricity, but also can hear the other person talking. This is killing two birds with one stone.

I am very happy to think that I am so smart and will become a scientist after a long time. Then mom came up and said, "You are great!" So I said modestly, "just so-so, the third in the world!" " At this time, Lei Jiayin also came from there: "I also came to share your phone with you." .

My invention composition 10 Last night, my father took me out for a haircut. The handsome barber gave me a 1 inch crew cut. I like it very much, but the nasty broken hair can't be washed clean. It sticks to my scalp, neck and collar. Today, I still feel itchy in my neck. I think I have to invent a multifunctional comb to solve this problem.

The shape of the comb I invented is similar to that of an ordinary comb. There are several buttons on the handle. The red button has the function of blowing. With a light press, hot air can be continuously blown out of the comb, and the hair can dry quickly when combing. There are many small holes in the teeth of the comb. Press the yellow button to generate suction from the small hole, and suck away the broken hair attached to the skin while combing your hair. You can also adjust the suction intensity at any time, so you don't have to worry about broken hair running into your neck anymore. Finally, when you press the blue button, the storage box of the comb can pop open and the collected broken hair can be dumped into the trash can.

I'm going to put some walking beads on this comb to make it have massage function. Massage the head, relax nerves, increase scalp blood circulation, and play a health care role. I comb my mother's hair every night, which can reduce her gray hair and keep her young and beautiful. Besides, I want to put an ink bag with hair dye in it. I can spray it evenly with one button and dye it while combing. It's really good and convenient. Grandma doesn't have to go to the barber shop to dye her hair.

This is my "little invention", a multifunctional comb that everyone can use.

My invention composition 1 1 I especially like to wear new clothes since I was a child. As long as it is my favorite new clothes, no matter what season it is at that time, I want to wear it. At that time, I always dreamed that if this dress could be worn all year round. If you ask me what I want to invent? Then I will definitely say, I want to invent a multifunctional dress.

My multifunctional dress is no different from ordinary clothes in appearance, but it looks thicker, the fabric is special and the color is white. There is a smiling little girl on the skirt, which is really cute.

I want to design many functions for it. Let me introduce my multifunctional clothes to you!

It has the functions of cooling and heating. There are two small switches on this cloth. The red switch is heating and the blue switch is cooling. If it is cold and snowy in winter, the red heating switch will automatically turn on to keep your body warm. If it is very hot in summer, the blue refrigeration switch will automatically turn on, making your body cool and comfortable. He just needs a few minutes' rest and a little energy to continue his work, which is particularly appropriate.

Another function of it is to keep it clean without cleaning. Unlike the clothes we usually wear. If dirty water spills on us, ordinary clothes will get dirty. And this magical dress was splashed on us with dirty water, and all the water droplets fell to the ground, leaving no dirty stains on our clothes. Do you know why? Let me tell you something, because clothes are coated with nano-paint, clothes will never get dirty.

Do you think this multifunctional dress I invented is good? Isn't it amazing? I hope it can be realized in the future.

My little invention composition 12 today I invented a pen container that shakes the table. Putting this pen container on the table is both beautiful and practical. This pen container is not made of wood or iron. Do you want to know what this material is? It's disposable paper cups and chopsticks.

At first, I wanted to make an umbrella. However, I had just finished the main part of the umbrella when the problem came. I want to stick the "forearm" of the umbrella on the disposable chopsticks, but I can't. So, I humbly asked the teacher for advice. The teacher helped me hold the "forearm" of the umbrella together. I bit off a large piece of tape and stuck it on countless "forearm". I thought it was done, but I pulled the umbrella pole hard. Wow! The umbrella pole actually fell off and I had to start all over again. My "umbrella" was finally made, in order to avoid the "tragedy" from happening again. I fixed the umbrella on three paper cups with plasticine. Oh! Great, my little invention has finally been made! However, I can't be happy too soon. I only heard a bang. My masterpiece fell down, so I had to ask the teacher for advice again. The teacher asked me to put the bottom of the paper cup in the invention. I carefully cut off the bottom of the cup, but the bottom of the cup always hangs on plasticine. I used my quick wits to put a layer of adhesive tape on the plasticine.

My masterpiece finally came out! This made me understand a truth: inventors are really not easy!

My invention composition 13 Today, my mother made a small production called slippers. It is made of green, red, pink and purple crepe paper, cardboard, pencil, rubber, double-sided tape and scissors. Let me introduce how it is done.

The first step in making slippers is to cut the green crepe paper into six pieces and make three pieces into a braid, thus completing two green braids. These two braids are really nice! Just like it's real. Then cut the red crepe paper into three pieces, then turn these three pieces into pig tails, then cut into two pieces of pink crepe paper, then cut into one piece of purple crepe paper, and then turn two pieces of pink crepe paper and one piece of purple crepe paper into pig tails. Finally, I stepped on the cardboard and drew two footprints. Enclose the edges of the cardboard with double-sided tape, and then cut purple crepe paper to enclose the edges. At this time, I showed an impatient expression. I dropped the cardboard and found it troublesome to make a pair of slippers. Then my mother said, "Let me give you a hand!" " "I carefully picked up the cardboard, glued the insole with double-sided tape, and then covered the place where there was no green braid. In addition, use a braid as a shoelace, then tie a bow with purple and pink and stick it on the shoelace, and finally you're done.

I looked at these beautiful slippers and let me know that I can't back down when I encounter difficulties. Persistence is the truth of victory.

My invention composition 14 Today, after lunch, I watched my grandmother wash oranges.

Suddenly, I heard a bang. So I craned my neck to see what happened. Grandma said to me, "An orange fell into the air-conditioning shelf below." Go and ask grandpa to bring it up, or it will be wasted. "Oh, well, I suddenly realized. I thought it was very interesting, so I climbed onto the bucket to see the fallen oranges. I saw it rolling from east to west under the action of the wind, like a naughty ball. Grandma urged me to call grandpa at once. I just "hee hee" smiled a few times and called grandpa.

Grandpa came over and asked, "What for?" "The orange fell!" "What? Did you drop the washbasin? " Grandpa's ears have never been very good. No, he heard wrong again. "No, no, no, orange!" I specially emphasized the word "orange". Grandpa finally listened clearly and walked there with his precious personal belongings-poker. He kept reaching down and carefully clamped it with a poker. However, the orange seems to be deliberately against him and refuses to come up.

Just when everyone was at a loss, I had an idea. I found a badminton racket and a clean plastic bag, tied the two handles of the plastic bag to the hole of the badminton racket, grabbed the handle of the badminton racket, put the badminton racket out and put the plastic bag down, so that it could be hard covered. Finally, the oranges came up.

"success!" I cheered. "The oranges are open!" My grandparents praised me for being smart.

My invention composition 15 One night, I had a dream:

I came to a big city. I saw a hotel where my mother and I stayed. We saw that there were no stairs and elevators, but the rooms were all upstairs. We asked the boss, "It's so strange here. Is this a hotel? " The boss smiled and replied, "Of course, but I won't give you the elevator until you book a room." "Oh, I see. We want to book a room. " I suddenly realized. We took the room card and elevator, and I couldn't wait to ask my boss, "How to use this?" The boss came to us, and I gave the elevator bar to the boss. I saw the boss throw one end of the elevator to the second floor, and one end of the elevator pole slid in the air. Soon, it was tightly attracted to the platform on the second floor like a magnet. The boss took a shelf from the table, put it under the elevator bar, fixed the other end of the elevator to the ground, and said to us, "You can go up. Put the elevator bar away when you go upstairs. I tried to walk up, but I seemed to feel a little shaky.

As soon as I got back to my room, I asked my mother, "Mom, why does this hotel use elevator bars?" Isn't that troublesome? Mom thought for a while and told me, "well ... it's probably because it's safer!" " "

The next morning, Ling's voice woke us up. We dressed in a hurry. When we opened the door, we saw a robot. He said to my mother and me in a friendly way, "Hello, my name is' Chef'. What do you want for breakfast today? " So my mother and I both reported our favorite food. The robot took us downstairs to a big restaurant. He finished our order quickly. We ate with relish, it was really delicious!
