Children's Works - Birth Record of Healthy and Effortless Schoolbags

      书包，是每个学生的必需品。行走在放学的路上，随处可见同学们前倾着身子背着沉重的书包的画面。据专家称，书包过重会影响正在生长发育的青少年的健康成长，尤其对脊椎和身高产生的影响颇为严重。

A backpack is a necessity for every student. Walking on the way after school, there are scenes of classmates leaning forward carrying heavy backpacks everywhere. According to experts, overweight backpacks can affect the healthy growth of teenagers who are growing and developing, especially with serious impacts on their spine and height.
Several students from Lu'an Road Primary School in Hefei have come up with the idea of improving their backpacks and are willing to do whatever they want. Draw sketches, consult experts, contact manufacturers to customize backpack models, and apply for two national patents. Now, after further research and development by the manufacturer's technical personnel, the "healthy and labor-saving backpack" has been launched into the market and entered thousands of households……

The Birth Process of Schoolbags

From creative generation to design conception, from on-site investigation and research to hands-on production, we continuously improve the shortcomings of the product in practice, showcasing the students' dedication in every step. In the process of invention and production, we proactively seek advice from experts, experienced teachers, and parents when encountering problems and difficulties that we cannot solve ourselves.

Experience in Technological Innovation and Invention

Zhen Xiaodong

2015年9月22日When I was in the second grade of elementary school, I became obsessed with conducting scientific experiments - homemade FI racing cars, homemade soda, homemade small street lights, and so on. After three years of exploration and experimentation, as my hands-on ability improved, I discovered many "points" in life that could be improved and optimized. For example, my mother often forgot to close the refrigerator door, which caused the refrigerator to freeze and food to spoil. Therefore, I created the "LED light with refrigerator door closing reminder device", And participated in the 29th Hefei Youth Science and Technology Innovation Competition in 2014, winning the second prize! This made me a little excited! Encourage me to continue to discover the pain points and difficulties in life and improve them!
On our way to school, my classmates and I were carrying heavy backpacks one by one. We couldn't help but think: when we were just in elementary school, carrying such heavy backpacks would be even heavier if we were in middle school? Our body is in the stage of growth and development. Will carrying such a heavy backpack affect the development of the spine? My friends and I began to search for information, consult orthopedic experts at the hospital, and consult experts on sports health at Science Island. We learned that a person's backpack should have a "weight bearing" limit of 10% of their own weight, so we developed the idea of a "healthy weight testing and labor-saving backpack". In the process of invention, my friends and I went through a series of tasks such as novelty searching, sketching, and making models. Although there were sometimes discussions and disputes, we were happy to improve our backpack by constantly communicating our ideas and demonstrating step by step. In the end, our backpack had 4 innovation points and 2 national patents!
In the innovation of backpacks, school leaders, tutors, and parents have provided us with timely encouragement and assistance, providing us with revision suggestions for our sketches. Each generation of backpack models has personally memorized them, "picking faults", inspiring us to continuously improve!
There is reward for what we put in. We won the first prize in the city competition and successfully entered the provincial competition. During the preparation process for the provincial competition, a manufacturer of backpacks contacted us to help us make backpacks. This is really a timely help, we are worried about how to make our backpacks more beautiful! After more than half a month of preparation, our backpack model has finally been made, which is much more beautiful than the first generation. At the provincial competition, my friends and I remained calm and answered every question. We unexpectedly won the first prize and successfully entered the national competition.
After returning, we will continue to work together to create ideas, improve the shortcomings of our backpacks, and make them more intelligent. Through continuous competition, I deeply realize that the path of technological innovation has no end, attracting me to constantly discover and improve
I hope more friends can take this innovative path and join us in loving science and embracing a smart life!

My Experience in Participating in Science and Technology Activities

Ma Haoxin

In early March 2015, our project participated in the 30th Hefei Science and Technology Innovation and Invention Competition, won first prize, and obtained two national invention patents.

In late March 2015, our project participated in the Anhui Provincial Science and Technology Innovation Competition and won the first prize, entering the national competition
In June 2015, our project participated in the 30th National Youth Science and Technology Innovation Competition and won the second prize
Achieving such achievements and honors is the result of the efforts of all members of our scientific and technological innovation team, and it is also inseparable from my own unremitting efforts in technological innovation from childhood to adulthood.
I have been fond of assembling and disassembling things by hand since I was young. I enjoy watching technology TV programs and am very interested in natural sciences, celestial sciences, physics, chemistry, geography, and human war history. When other children are playing outside, I am learning about this knowledge from books and television networks. Therefore, my understanding of science is much better than that of ordinary classmates.
Since joining the technology innovation group, I have learned a lot of useful basic physics and chemistry knowledge. Therefore, when we formed the participating group to determine the backpack project, the knowledge I learned has played a certain role. At first, the students gathered their ideas and went from the previous "labor-saving backpack" to the "healthy and labor-saving backpack". The backpack also evolved from being able to be easily weighed and judged by parents whether it was overweight, to a cross shaped shoulder strap. At the same time, the shoulder strap was widened to improve the backrest, making it a relatively formed backpack. During this period, we still made a lot of new creative improvements and continuously made new backpack models, and continued to improve on top of it, Finally, the functions of the backpack are determined, with the following characteristics: 1. It can be weighed to remind students whether the backpack weight exceeds their burden. 2. Cross straps make the backpack snug and effortless to carry. 3. Widen the shoulder strap, increase the stress area, and reduce the pressure on the shoulders. 4. The shape of the back is more suitable for the curvature of the human body, while increasing breathability. 5. The bottom of the backpack has creatively added a hard base plate, which can support the backpack to prevent deformation, achieving labor-saving from a mechanical perspective. 6. Some other auxiliary functions have also been added, such as GPS positioning, safety signs, MP3 function (listening to English and Chinese), navigation (the bus route and which bus students need to take, prompt where to get off, and provide convenience for students).
We worked hard and gained hard, and the efforts of our members were not in vain. With the help and encouragement of our guidance teachers and parents, our work participated in the competition in Hefei City and the science and technology innovation competition in Anhui Province. In the end, we passed the exam and entered the national competition, ultimately achieving good results.
This technological innovation activity has led me through the entire process from project initiation to completion and application, from searching for projects, collecting creativity, hands-on production, and expert problem-solving. It took me over a year to understand that any technological innovation not only requires a lot of wisdom and sweat, but also a spirit of perseverance to support.
After achieving certain results and under the guidance of the teacher, our group members will continue to make more improvements to the backpack. We believe that in the near future, the backpack we invented will have more practical functions in people's expectations, reduce the burden on students, and facilitate their learning and life.
