The problems of invention are all around people. As long as you are a dedicated person, you will definitely succeed.
There is a young man named Yu Ruqiang in Qingxian County, Hebei Province. He found the problem he discovered from the problems around him. In 1987, Yu Ruqiang failed the college entrance examination. As a child of a farm family, I have been studying for many years but have not been able to achieve my goal. Due to family conditions, I am unable to continue going to school. At that time, he could not help but feel sad and confused.
Yu Ruqiang was unwilling to spend his life doing nothing. After working, he insisted on reading and self-study, always thinking about making something famous. One cold winter night, he looked at the red-hot coal stove at home and suddenly thought: Why can't he store part of the heat in the stove and release it when needed? If such a stove could be invented, it would not only save energy but also bring convenience to the folks.
The flash of inspiration lasts only a moment, and it is not easy to turn inspiration into results. In order to make up for his lack of knowledge, he studied college physics courses on his own without sleep and food, and also read extensively the relevant books he could find. During that time, he devoted himself wholeheartedly to it, day and night, sketching one after another according to the appearance of the energy-saving stove he imagined, and calculating the calculations over and over again. Some people said that he was "crazy."
Now that we have the drawings, we can actually start testing without materials and funds. The family was in trouble and could not afford money, so Yu Ruqiang used the knowledge he learned to modify agricultural machinery for others, earning part of the income, and then used this part of the income to invest in experiments with energy-saving furnaces. After many twists and turns, he first successfully developed a coal-saving food oven by collecting waste heat from coal-fired stoves. However, this kind of stove can only meet the needs of some industrial and commercial households, and cannot yet enter the homes of ordinary people.
After several years of study and practice, although he did not achieve his ideal design effect, Yu Ruqiang strengthened his confidence. Once, he was inspired by observing a steam boiler, and then designed a conversion device on the original oven stove to convert the collected and stored heat into high-temperature and high-pressure steam, which was used to boil water for cooking. Immediately afterwards, he reorganized it to form an energy-saving coal-fired stove that was small in size, fully functional, and suitable for home operation.
At the end of 1997, several experts from Beijing and Shijiazhuang went to Qingxian County to evaluate Yu Ruqiang’s achievements. He lit the stove for the experts on the spot, boiled 4 kilograms of cold water in less than 3 minutes, and steamed a pot of steamed buns in 20 minutes. At the same time, he also performed multi-functional performances such as steaming, boiling, roasting, and stir-frying. The appraisal results show that the energy-saving stove can satisfy a family of six people by using only 2 kilograms of coal per day. With an additional 6 kilograms of coal, it can also run two sets of radiators and a shower. Today, the energy-saving coal-fired stove he developed has applied for two national patents, of which the design patent has been authorized.
Zhang Yi is a middle school student in Yunnan Province, my country. He participated in the science and technology group organized by the school and actively carried out small invention activities. His invention "New English Dictionary Usage and Compilation" won the gold medal at the 11th National Invention Exhibition and the "Wang Danping Youth Invention and Creation Award".
Zhang Yi’s secret to invention is to grasp the problems around him and start from researching and solving problems encountered in study and life to find inspiration for inventions.
It was Zhang Yi’s first invention to improve the cooling oil box when he was in the second grade of junior high school. His family lives next to a bamboo forest, and every summer there are many mosquitoes. As long as the doors and windows are not closed at night, mosquitoes will come quietly. Under the repeated bites of mosquitoes, he had to seek help from cooling oil. But the cooling oil box was at odds with him at this moment, and no matter how hard he tried, he couldn't open it. The buzzing sound of mosquitoes after their meal lingered in his ears, and the large mosquito bites on his body were itchy. In desperation, he dropped the cooling oil on the ground. But this didn't work. The cooling oil box rolled on the ground several times, still clenching his teeth.
In his anxiety, inspiration suddenly emerged from Zhang Yi’s mind: “Is it possible to improve the cooling oil box to make it easier to open?” So, based on this idea, He improved the cooling oil box structurally, making the base of the cooling oil box concave and turning it into a crescent shape, while the shape of the lid remained unchanged, but the inner wall was separated from the base, which increased the friction area and made it easier to Open and have a good seal.
After a lot of hard work, the "new cooling oil box model" was finally made. Zhang Yi won the second prize at the state level for this invention. Although it was not a grand prize, you should know that this was his first invention.
Having the experience of invention for the first time, Zhang Yi’s creative thinking was opened up. In the first semester of the third year of junior high school, he invented "dual-purpose slippers", won the provincial third prize, and was admitted as a member of the Dehong Prefecture Invention Association. In the same year, he wrote a paper on "Youth Creativity Development and Mass Creative Activities", which was printed and distributed throughout the state by the State Invention Association. It was during this period that he came up with the idea of ??improving the English dictionary.
After a long period of analysis of English words and computer programming, Zhang Yi accidentally had this inspiration: "Can the characteristics of vowels in words be used to indicate the position of words in the dictionary?" . So he initially wrote "New English Dictionary Usage" based on inspiration.
Zhang Yi’s invention breaks the past habit of using 26 English letters in order to find and organize English dictionaries, and uses the characteristics of vowels in words to indicate the position of words in the dictionary. Therefore, Able to see words, know page numbers, and flip through dictionaries at an incredible speed. (Note: English dictionaries checked in this way need to be re-edited).
"New English Dictionary Usage" has wide practicality. It can not only be used in dictionaries and dictionaries such as English-English, English-Chinese, Han-Cha-English, and Han-Cha-Han, but it can also be used in characters of other nations and other countries that have this characteristic, and can even be used in today's society. on the widest range of computers, which may lead to a major change in the arrangement and search of dictionaries.
The invention experience of two friends Zhang Yi and Yu Ruqiang tells us: the problem of invention is all around us, and as long as we are determined, we will definitely succeed.
