我是小小发明家作文
篇一：：我是小小发明家
每天上学的路上，我都看见在马路上来往的车辆都有烟雾从汽车后面排出。
我想“这种烟雾人闻了都会咳嗽，肯定会破坏环境，这样的话，花草树木都会死的。
”所以，我想发明一种汽车，这种汽车的外表和普通汽车的外表一样，但是，它不会排出这种有害烟雾，因为这种汽车的能量是一种特殊的电池，这种电池装在汽车里可以维持汽车跑一个星期不用加汽油，因
为它有电池，电池就是能源。
同学们，你们觉得我的这个发明
好吗？
篇二：我是小小发明家
去年五一，爸爸妈妈带我去太公湖，我看见路边有一座垃圾山：白色的塑料袋被风刮得满天飞，袋子里充满了空气，白胖胖的，空气中飘散着臭烘烘的味道，恶心极了，我赶紧捂起鼻子，对爸爸妈妈说：”快走吧，这里太臭了?”
我曾经在教室的垃圾桶，生活区里的垃圾箱附近无数次地看到这样的情景.我觉得生活中垃圾实在太多了，它的危害很大，可以污染环境，焚烧后它们变成了毒气，危害大自然和人类.。

我是小小发明家小学优秀英语作文全文共6篇示例，供读者参考篇1I am a Little InventorHi there! My name is Tommy and I am a little inventor. I love creating new things and finding solutions to problems. Ever since I was very young, I've been curious about how things work and I'm always trying to take them apart and put them back together again. Sometimes it drives my parents a little crazy, but they've learned that it's just who I am - a mini engineer and mad scientist!My very first invention happened when I was just five years old. My baby sister kept dropping her pacifier on the floor, which would make her really upset. The pacifier would get all dirty and my mom would have to go find a new clean one. I decided there had to be a better way, so I grabbed some string and duct tape and made a little leash to attach the pacifier to her shirt. That way, if she dropped it, it would just dangle there instead of hitting the floor. My sister loved it and it saved my mom a lot of hassle!From then on, I was hooked on inventing. One of my favorite creations is my bedtime storybook robot. Basically, it's a little robot that can read books out loud by scanning the pages with a camera. It has a cute robot voice and sound effects too. Now instead of my parents having to read me stories every night, I can just hit a button and let the robot do it for me! My friends all think it's so cool.Another invention I'm really proud of is my super soaker water balloon launcher. It's like a huge slingshot that can fling water balloons an incredibly long distance. I used a bunch of rubber bands, a plastic bucket, and some PVC pipe to make it. With this baby, I can absolutely soak my neighbors' kids from my backyard! They get so mad, but they have to admit it's an impressive piece of engineering.Sometimes my inventions don't work out quite as planned though. Like the time I tried to make jet-powered rollerskates. The basic idea was to strap these little engines onto a pair of skates to make them go really fast. It kind of worked...a little too well actually. I fired them up and immediately lost control, crashing right through the garage door! My dad had to ride his bike to chase me down the street before I seriously hurt myself. Those skates definitely need some more work.My parents have learned that if they ever can't find me, I'm probably down in the basement working on my latest contraption. We turned our basement into a little inventor's workshop for me, which is awesome. It's got workbenches, tools, spare parts, you name it. I'm continuously taking old electronics and toys apart to see how they function and re-purposing the pieces into new creations.My friends used to think I was kind of weird with all my tinkering and making weird machines, but now they've come to really appreciate it. Anytime they need something fixed or modded, they just bring it to me. Like when my friend's remote control car stopped working - I was able to take it apart, repair the circuit board, and soup it up with a more powerful motor. Everybody wants the "Tommy treatment" on their toys now!I've gotten so into building robots and machines that I've started learning computer programming too. I taught myself some basic coding so I can make robots that are programmable and can follow different routines based on inputs from sensors. I just finished a little robot that can sense where sound is coming from and automatically orient itself to face the noise. I'm going to enter it into our school's science fair this year.My biggest goal is to one day have my own TV show about making cool inventions and doing science experiments. Can you imagine how fun that would be? Each week I could come up with a new project or challenge and take viewers through the process of building it. Maybe I could have other kid inventors as guests too. I could get so many ideas out there and inspire other kids to be makers and creators instead of just consumers.I know being an inventor probably isn't the most normal career choice, but I really think it's my calling. The world is full of problems and challenges that need fresh ways of thinking to solve them. By constantly tinkering, experimenting, and thinking outside the box, who knows what awesome inventions I could come up with? Maybe I'll invent a new source of clean energy, or some mind-blowing medical technology, or the next big breakthrough in transportation or computing. The possibilities are endless when you combine science, math, creativity and a driven desire to always keep learning and pushing boundaries.For now though, I'm going to keep having fun making my silly little contraptions and trying to one-up myself each time. I might still be a little inventor, but you never know - maybe my cool robot or high-powered water balloon launcher could be the start of something big! All I know is that I was born to create,build and invent. The path of a mad scientist definitely isn't the easy road, but it's the perfect journey for me. Thanks for reading and wish me luck!篇2I Am a Little InventorHi there! My name is Tommy and I'm 10 years old. I love science and inventing things. You could say I'm a little inventor! I get tons of ideas for new inventions every day. Sometimes the ideas are big and sometimes they're small, but I always try to make them a reality.One of my first inventions was the Soggy Cereal Saver. I really hate when my cereal gets all soggy before I can finish eating it. It's just so gross and sloppy! So I invented a special bowl with a lid that goes on top. The lid has a little straw hole so you can still eat the cereal, but it keeps the milk from getting to the cereal and making it all soggy. My mom was my first customer and now my whole family uses the Soggy Cereal Saver bowls!Another problem I solved was stinky baseball caps. My brother's baseball caps always smelled terrible after he wore them. He would leave them in his room and they got super stinky.So I made him the Odor-Be-Gone Cap Refresher! It's a little plastic container that you put baseball caps into. It has a built-in fan and air filters to suck out all the smelly odors and make the caps fresh again. Now my brother's caps don't stink up his room anymore. He thinks I'm a genius!One of my favorite inventions is my Pet Snack Launcher. I have a dog named Buddy who's really energetic and loves chasing after treats. The Pet Snack Launcher can fling little treats across the room for Buddy to chase. It's like a t-shirt launcher but for pet treats instead! Buddy gets tons of exercise running around catching his flying snacks. And it's funny to watch too! I should start selling these for other pet owners.I get my inspiration from looking at the world around me and thinking "how could I make this better?" Anything that's inefficient, annoying, or just not as good as it could be gives me an idea. I'll spend hours sketching designs and prototypes in my special inventor's notebook. Then I'll gather up supplies from around the house or garage and build my new creation. My parents are really supportive and let me tinker as long as I clean up after myself.Building and inventing is just so much fun. I love working with my hands and tools to put ideas into physical form. Andwhen one of my inventions actually works, it's the best feeling ever! Sometimes friends or family members will look at my inventions and say "wow, you should try to get that patented and sell it." And you know what? Maybe I will someday! For now though, I'm happy just being a little kid inventor having fun and working on my next big idea.Who knows what amazing inventions I'll come up with as I get older? Maybe I'll invent a cool new kind of car, or a machine that can teleport you places, or some awesome new toy that every kid will want. I have a million ideas swirling in my brain at all times. The possibilities are endless for a creative inventor like me!I hope this essay inspires other kids to start inventing too. All you need is imagination, curiosity, and a desire to make things better. Oh, and maybe some basic tools, art supplies, and a understanding parents who don't mind a little mess here and there! Start looking at problems in a new way and think about how you could design a solution. That's what being an inventor is all about. Just ask questions, explore ideas, and have fun creating. Who knows, you might just invent the next big thing!篇3I am a Little InventorHi everyone! My name is Timmy and I'm 9 years old. I love inventing things and making new creations. You could call me a little inventor! I've always had a really curious mind and I'm always trying to figure out how things work. Instead of just taking things apart though, I also like putting things together in new and different ways.It all started when I was 5 years old. For my birthday, my parents gave me a big bucket of LEGO bricks. At first, I just built the things that were on the instruction books that came with the sets. But after a while, I started making my own custom creations.I made trucks, spaceships, robots, and all kinds of crazy contraptions that I thought up in my imagination. My parents were so impressed with my LEGO skills!When I was 6, I got really interested in science and engineering. I watched a lot of shows and videos about how things are made and how they work. I was fascinated by machines, electronics, chemistry, you name it! For my next birthday, I asked for a kids science kit. It came with all these little tools and components to make basic circuits, motors, and little robots. I spent hours tinkering away, following the instructions but also experimenting on my own.Pretty soon, I had moved beyond the basic kits. I started taking apart old toys, electronics, and appliances that my parents didn't need anymore. I would salvage the parts - the wires, motors, batteries, lights, you name it. Then I would try to rebuild things using the recycled components in new ways. Sometimes they worked, sometimes they didn't! But I never got discouraged. Every failure was just another learning experience.One of my first big "inventions" was a little robot dog I made from an old remote control car and some popsicle sticks. I used the motors and wheels from the car for the body and legs. Then I made a head and tail from the popsicle sticks. When you turned it on, the little robot dog could scoot around and wag its tail! My parents thought it was so clever.Another fun invention was my "night walker" shoes. You've heard of night lights right? Well, my night walker shoes basically had little LED lights built into the soles. Whenever I was walking around in the dark, the motion would activate the lights so I could see where I was going! No more stumbling around or turning on bright lights to find my way. My night walker shoes gave just enough of a glow.Probably my most ambitious creation so far has been my solar-powered rotating garden. Basically, it's a bunch of planterboxes mounted on a big lazy susan type of platform. There's a small solar panel that powers a little motor to slowly rotate the plants throughout the day. That way, all the plants get equal access to sunlight instead of just the ones on one side of the garden. It's been great for growing veggies, herbs, and flowers! I'm really proud of that one.Whenever I get stumped on a project or run into problems, I don't give up. Instead, I start doing research to better understand the science and mechanics behind whatever is giving me trouble. I read books and scour the internet. I watch videos and try to learn from others' successes and failures. Slowly but surely, I figure out where I went wrong and take another crack at it.Not only is it super fun to dream up and build my little inventions, but I feel like I'm learning invaluable skills for the future. Skills like critical thinking, problem solving, perseverance, and good old-fashioned tinkering. I'm exercising my creativity and curiosity. Who knows, maybe I'll grow up to be a famous inventor one day! Or an engineer, scientist, maker, you name it. The possibilities are endless when you're a kid inventor.My parents have been endlessly supportive and encouraging of my inventive hobbies. Sure, there's been a few messes to cleanup here and there. And yeah, sometimes I drive them a little crazy with my nonstop tinkering and leaving components all over. But they've been amazing篇4My Inventions and How I Came Up With ThemHi there! My name is Timmy, and I'm a 9-year-old inventor. I know what you're thinking - "A 9-year-old inventor? That's crazy!" Well, let me tell you all about my awesome inventions and how I came up with them.It all started when I was 6 years old. I was playing with my toys, and I kept getting frustrated because my action figures kept falling over. That's when I had a brilliant idea - what if I could make a toy that could stand up on its own? I started experimenting with different materials, and after a lot of trial and error, I created my first invention: the Self-Standing Action Figure!The Self-Standing Action Figure has a special weighted base that keeps it upright, no matter what crazy poses you put it in. It was a huge hit with my friends, and I even sold a few to my neighbors. That's when I realized that I had a real talent for inventing things.After that, the ideas just kept coming. One day, I was trying to eat a popsicle, but it kept dripping all over my hands. That's when I invented the Drip-Free Popsicle Holder. It's a little plastic tray that catches all the drips, so you can enjoy your popsicle without making a mess.Another one of my inventions came about when I was trying to do my homework one night. I kept losing my pencils under my desk, and it was driving me crazy. That's when I invented the Pencil Finder 2000 - a special pencil case with a built-in flashlight and magnifying glass, so you can easily find any lost pencils.But my favorite invention has to be the Automatic Dog Walker. My dog, Buddy, is always begging to go for walks, but sometimes I'm just too busy with homework or playing with my friends. So, I invented a little robot that can take Buddy for a walk all by itself. It has a built-in leash and treats, and it follows apre-programmed route around the neighborhood. Buddy loves it, and now he never has to wait for me to take him for a walk.But that's all part of the fun of being an inventor. You have to be willing to take risks and learn from your mistakes. And you never know when you'll have your next big idea.Speaking of which, I've got a great new invention in the works. It's a special backpack that can carry all your schoolsupplies, plus it has a built-in snack compartment and amini-fridge for keeping your drinks cold. I haven't quite worked out all the kinks yet, but I'm sure it's going to be a huge hit with kids everywhere.So, there you have it - the story of my life as a young inventor. It's been a wild ride, but I wouldn't have it any other way. Who knows what other amazing inventions I'll come up with as I get older? The possibilities are endless!篇5I Am a Little InventorHi there! My name is Alex, and I'm a little inventor. I'm only 10 years old, but I've always loved taking things apart and putting them back together in new ways. My parents were a bit worried at first when I started dismantling the TV remote and the kitchen blender, but once they saw how careful I was, they became really supportive of my tinkering.It all started when I was 6 years old and got a set of building toys for my birthday. I loved snapping those little plastic pieces together and following the instructions to create different models like cars, spaceships, and robots. But after I had built everything in the set, I started experimenting by combining thepieces in my own crazy ways. That's when I made my first real "invention" - a wacky looking doghouse made from the leftover pieces.My parents thought it was so funny and creative that they started giving me old electronics and other discarded household items to take apart. I'll never forget the day my dad brought home an old busted printer from work. I spent hours carefully disassembling it, studying how all the gears, motors and circuits worked together. Once I had it all laid out, I started recombining the components in new configurations - that's how I made my second big invention, the "Page-Turning-matic 3000"!It was a little robotic arm that could flip the pages of a book using some printer parts and a motor from an old CD player. It didn't always work perfectly, but my parents were so impressed that they let me keep taking more things apart. From then on, my mom always checked with me before throwing anything away in case I could use it for my next project.In second grade, I got really interested in renewable energy after we learned about it in science class. I spent a whole summer collecting bottles, cans, cardboard tubes - anything I could find - to build a solar powered ovenmobile! I covered a little red wagon in aluminum foil and rigged up some old laptop batteries and asolar panel I made from pop can lids. It created a miniature greenhouse effect that got warm enough to bake cookies! My dad loved helping me with that one.When I was 8, I built a brilliant "germinator" for our garden out of an old microwave and some UV lights. It used the microwave's rotating plate to slowly turn seedling trays while the UV lights helped them grow big and strong before transplanting them into the ground. Simple, but effective! Our vegetable garden was amazing that year.Last year, I constructed my most advanced invention yet - a powerful little electromagnetic catapult! I used an old computer's hard drive motors and magnets to build it. On the catapult arm, I attached a metal rod that would get flung forward when I disrupted the magnetic field using some precisely timed electric currents. My dad had to stop me from trying to launch the cat.... but it could toss a tennis ball pretty far! I'm already working on making it portable for the school science fair next month.My parents have been really supportive, helping me gather materials and giving me tools and workspace. As long as I'm careful and don't make too big of a mess, they just leave me to my tinkering. My little sister thinks I'm kind of weird, but shedoes enjoy being one of the first to try out my new creations. Sometimes they even inspire her artistic side - like when she decorated my water-powered PVC pipe xylophone with all sorts of crazy colors and patterns.My friends think my inventions are pretty cool. Sometimes I'll bring one of my simpler projects to school for show-and-tell, which is always a big hit. A few of them have started saving their old toys and random household items to pass along to me for future inventions. Thanks to them, I now have an endless supply of potential building materials!I love using my problem-solving skills and creativity to envision new possibilities for everyday objects. To me, a broken hairdryer isn't just trash - it's a treasure trove of motors, wires, vents and housings just waiting to be recombined into something totally new and amazing. Maybe my little catapult could become the inspiration for a high-tech pitching machine for the school baseball team? Or those old PC cooling fans could be used to make an energy-efficient AC unit? The possibilities are endless when you start thinking outside the box.Who knows, maybe I'll grow up to be a famous inventor someday? I'd love to help create incredible new technologies to solve the world's biggest problems in environmental protection,poverty, health care and more. Just by reusing discarded items in innovative new ways, we could really make the world a better place. For now though, I'm thrilled just to spend my free time in my little inventor's workshop, following my curiosity to see what amazingly fun or useful thing I can build next. Keep an eye out, world - this little inventor has got some huge ideas in the works!篇6I am a Little InventorHi there! My name is Tommy and I'm 9 years old. I love science and inventing things. I'm always coming up with new ideas for cool inventions that can make life easier or more fun. My parents and teachers call me a "little inventor" because I'm always tinkering and building new contraptions. I'll tell you all about some of my greatest inventions!My Very First InventionMy very first invention was the "Buddy Feeder 3000". I made it when I was 6 years old. Our dog Buddy would always beg for food when we were eating dinner. Instead of having to sneak him food from the table, I invented an automatic dog feeder that would give Buddy a treat whenever he pushed his nose against a big red button. It was made out of a plastic storage bin, sometubing, and a battery-powered candy dispenser I took apart. Buddy loved it and my parents thought it was pretty clever!The Haunted House-O-MaticOne of my most popular inventions is the "Haunted House-O-Matic" that I built for Halloween a couple years ago. It's a little machine that makes any house look scary and haunted. It has strobe lights, a fog machine, and recordings of spooky sounds like howls, creepy laughs, and chains rattling. You just place it outside your house and turn it on. It was a huge hit on our street - all the neighborhood kids thought our house was the coolest haunted house ever! I even won a prize from the community center for it.The Water Balloon UltrablasterMy favorite invention of all time is probably the "Water Balloon Ultrablaster". This one took me months to get right. It's a powerful water balloon launcher that can fling balloons over 100 feet! The key was using a big air compressor and a specially designed launch tube. I used a lot of recycled materials like plastic bottles, rubber tubing, and an old bike pump. It was perfect for epic water balloon battles with my friends last summer. We had an absolute blast...until I accidentally hit Mr. Wilson's brand new car! Oops!The UnbreakarapptorMy latest creation is an invention I call the "Unbreakarapptor". It's a special protective case I designed for my mom's smartphone, because she is always cracking her screen. The Unbreakarapptor is made from a rubbery plastic that absorbs shocks if you drop your phone. It also has a built-in screen protector and seal to keep out water, dirt and crumbs. I 3D printed the case at the library and gave it to my mom as a gift. So far her phone has survived a few tumbles onto the concrete and being dropped in the bathtub! Mom says the Unbreakarapptor is her new best friend.My Inventing SecretsYou might be wondering how I come up with so many clever inventions at such a young age. Well, I'll let you in on a few of my secrets:I read a ton of books and watch videos about science, engineering and how things work. That gives me ideas and knowledge to build off of.I never throw anything away - I save every bolt, battery, hose, bottle cap, you name it. You never know when a random household item could be a key part of an invention!I just use my imagination and think about problems that need solutions. Then I brainstorm as many wacky ideas as possible to try to solve it.I'm not afraid of failures or mistakes. Sometimes an invention doesn't work at first, but I learn from it and keep tweaking until I get it right.My Inventing DreamsInventing is just so much fun for me. I get such a kick out of building new gadgets and watching them actually work. It makes me feel proud and accomplished.I dream of becoming an famous inventor when I grow up and starting my own company to manufacture and sell my inventions to the world. Maybe I'll invent a car that runs on soap bubbles instead of gas. Or a special umbrella that stops rain from ever falling on you. Or jet packs for everyone! The possibilities are endless if you use your creativity.One of my biggest heroes is Thomas Edison, who invented the light bulb, phonograph, and so many other revolutionary things. He supposedly failed 10,000 times before finally getting the light bulb to work. But he refused to give up and keptpursuing his vision. That's the kind of determined inventor I hope to be too.So there you have it - that's my life so far as a "little inventor". Who knows what amazing contraption I'll dream up next? You'll just have to wait and see. The future is looking very inventive!。
精选作文我是小小发明家【10篇】
作文我是小小发明家【精选10篇】记得前段时间，妈妈贫血严重，医生帮妈妈开一瓶三七粉，由于三七粉有点苦，妈妈为吃它而苦恼。
看着妈妈苦恼的样子，我很心疼，就灵机一动，如果也能把三七粉用胶囊装起来那就太好了。
于是我就到药店买回空胶囊，关到书房帮妈妈加工，可是把三七粉装到胶囊里也不是一件容易的事，由于胶囊口太小粉末又细，倒了满手都是，于是就停止工作，在书房转悠，看到书柜里有一包吸管，发现吸管的口比胶囊小一点，这下我就像发现新大陆一样，光想不做是不对的，说干就干，就把吸管插到三七粉里，一捏、一取、一碰粉末就像滑滑梯一样全滑进去。
妈妈下班回来，我把装在胶囊里的三七粉交给她，妈妈表扬我是“小小发明家”，我高兴得一蹦三尺高。
昨天晚上，我和爸爸在公园里活动活动，又去大润发买几瓶饮料，就回家打乒乓球了。
可是打着打着，因我光打飞球，害的爸爸在售楼处里上蹿下跳，筋疲力尽，看着爸爸满头大汗的样子，我突发奇想，要是能造一个能打乒乓球的机器就好了。
我觉得造这个机器人，必须要让它听到乒乓球的声波，辨别地方，然后打，它的功能：1、有发球：在它手上放一个盆子，把它要发球的姿势传给它，然后它就拿球便发。
球没了，它就有一个自动感应器，就自动关闭，我们给它放上球，按开关，它就又开始。
2、练正手：它还是和发球一样，只不过它的打球姿势要再换，然后只需一个球，因为只用一个球，所以一定要在脚上安个轮子，这个轮子就相当于我们的手，只要机器人头部的传输功能发个号令，让它向左或向右走几米，轮子便会照应指令去做。
3、练反手：练反手就和前面差不多，只不过光改一下发球姿势便可。
也可以再造一个捡球机器人，辨别声波的位置，然后判断出前方的路线捡球，然后就一些配置让捡球机器人知道发球机器人的位置，然后放入盆中，要是打到楼梯上，它的腿会变成弯曲形式，为了保持平衡，可以利用不倒翁的原理让机器人不至于倒下，并且会让机器人明白前方楼梯的长度然后迈步，下楼梯的时候不用上楼梯一样慢，它的腿部会重一些，保持平衡，然后脚上会出来个滑轮，然后就飞速滑下楼梯。
我是小小发明家_三年级作文
我是小小发明家【时光穿梭机】徐逸凡最近，我看了动画片《多啦A梦》，特别羡慕大熊家有个抽屉式的时光穿梭机，它可以在过去与未来之间穿梭。
于是我也打算发明一个时光穿梭机。
首先，我找来了宇宙中磁场最强的能量石，再添加各种化学元素，使能量石磁性变强，磁场范围增大。
再把这块超强磁石放入一个文具盒大小的磁能量控制盒中，把盖子封紧。
又在盒子上安装了两个按钮，一个是红色的，按下去可以回到过去；另一个是蓝色的，按下去可以穿越到未来。
时光穿梭机研制成功了，我可要赶紧试一试。
我首先选好了目的地，按下红色按钮，只见盒子上的灯猛地一闪，我的眼前一片白光，一秒钟之后，我的视线渐渐清晰。
我望了望四周，发现自己确实来到了目的地——2014年6月20日。
那一天，我和同学发生了一点小争执，扇了后排同学两个耳光，同学的脸像烤熟的面包一样肿了起来。
老师气的给妈妈打电话告状。
一回到家，我就被罚站，这一站就足足站了五个小时，直到深夜，妈妈才放我去睡觉。
可是现在不同了，在我马上就要扇同学耳光时，我忍住了，一场“灾难”就此避免。
当然后面老是请家长的事也就根本没有发生。
接下来，我又穿越到前几年的期中期末考试现场，把原来做错的题，全都一一改过，填上老师讲过的正确答案。
有了这台时光进，全班第一不再是梦！我又按动了蓝色按钮——去看看我的未来。
只见白光一闪，我来到了2034年12月17日，那天是我三十岁生日。
那时的我已经是一家公司的财务总监啦，月薪三万三千元，我真为自己自豪啊！我又穿越到了五十岁。
发现天边有一个小行星正以光速飞来，马上就要撞上地球了，难道6500万年前的历史要重演吗？那么人类将会灭绝，太可怕了，我急忙返回到现实。
回到现实，刚好已经上课，数学老师正在读作业未交同学名单。
“啊！我竟然没交！”我连忙掏出作业递给老师，老师把我的学号“23”划掉了，对我说：“你是8个没交作业的同学里最后一个交的。
好了，回去吧！”我赶紧回到了座位。
那天晚上，我又穿越到了50年后，发现小星星接近地球时，被一个横扫而来的彗星撞开了，地球幸免于难。

今天我要向大家介绍我的发明，那就是“防丢眼镜”。
说起我的发明，它的由来是因为我老是把眼镜搁在桌上，走远了才发现眼镜不见了。
要是我有一个能够防止眼镜丢失的装置就好了。
于是我就想到了“防丢眼镜”。
它的运作原理是这样的，我在眼镜上面装了一个小小的立体印花，印花上还设有几个小钩子，可以把耳杆勾住。
这样我只要不把眼镜放在桌子上或是随意乱扔，就不会出现掉落、丢失的情况了。
我的这个发明不仅仅是解决了我的眼镜丢失问题，也能够为那些经常丢失眼镜的人们带来便利和实惠，解决他们的后顾之忧。
我相信这个小小的创意定会给人们的生活带来更多的便捷和创新。
作文要点分析：1、本文讲述的是作者发明的“防丢眼镜”，除了广告语气比较浓之外，整篇文章几乎没有什么花哨的辞藻，而是以平实、快捷、简洁的语言展现了这个实用性强的发明。
2、文章通过引入防丢眼镜的缘由进行开篇，从而引出了自己的发明，着重表达了小小创新的重要性和价值。
3、用词方面也较为简单，容易被年龄较小的学生所理解。
【作文二】我是小小发明家-我的垃圾分类机器人我是一个小小发明家，我的大脑里总是充满了那些有趣的点子和出奇的想象。
今天我想要向大家介绍我的最新发明——垃圾分类机器人。
随着人类生活水平的不断提高，我们所面临的垃圾问题也日益突出。
大量的垃圾无法及时得到分类处理，对环境和人类健康造成了极大的影响。
因此，我发明了一种简单易用的垃圾分类机器人。
我的机器人运作非常简单：只需要把待处理垃圾投入物料通道中，它就能根据自身的传感器来自动识别、收集和分离各种垃圾种类。
在分类垃圾的过程中，利用人工智能，机器人中的程序会发挥作用，利用已知的算法，对垃圾进行自动识别和分类。
我之所以想象出这样一个机器人，是因为我看到了垃圾问题的危害性，而且大量的垃圾对于环境的破坏和污染也是不可忽视的。
