I write invention patent documents myself, and I want to teach for free, but no one responds. For example, during the power grid freeze disaster last year, I solicited students online to provide free guidance in writing power grid anti-freeze invention patents. In fact, I came up with the idea, and the other party entered it into an electronic document, and he applied for it himself. Since he is a student, he can just pay 560 yuan to the National Patent Office. I instruct him to pay it to the National Patent Office on his own, but the money is not in my hands; We also visited many local schools and sent out many flyers, asking students who stayed in school during the holidays to participate, especially asking the school’s work-study department to contact us. We also posted on local forums and on volunteer websites, but no one responded! What the Chinese want is cash! You need to make money immediately and do big projects. The following requirements are put forward for the construction of domestic science popularization exhibition halls. The same requirements are put forward for teaching experiments, graduation theses, teachers' papers, and vocational training in colleges and universities, and they should be strictly promoted and implemented as a national policy:

The key is that the exhibition items must be innovative, and the technical information of the exhibition items must be fully disclosed

Existing exhibition items have clear flaws in design and manufacturing, high damage rates, and demonstrations and interactions cannot reveal them in a profound way. The nature of engineering and science; each exhibition item does not have an electronic document system that can be downloaded for free or at a low price by visitors, and a detailed explanation. In particular, the procurement location and purchase price of materials and components must be fully disclosed. Non-standard The machining process, debugging process, design and manufacturing constraints of components, I hope visitors will go back and give specific suggestions for simplification, improvement and development in the future, so that visitors can make commercial products for sale; existing exhibit manufacturers are They come here to make money and keep the design information confidential, which makes the maintenance cost high and the maintenance cycle long (some have to be shipped back for repair), which obviously affects the exhibition effect; we plan to provide more than 100 innovative exhibition items free of charge, which will be provided by students from nearby universities. Made by students, only need to provide public transportation expenses. This is the national strategy and the foundation of the country; in particular, it should be pointed out that the current undergraduate and graduate experimental courses, graduation thesis, and innovative research lack the support of engineering technology, turning the country's precious resources into garbage, so it is difficult to find employment, and products are not available in the market. The quality cannot go up in the international market, and it has no high-end deterrent effect on developed countries.

With this, the ticket price is not a problem and can be increased. Not only students who are studying will come, but also unemployed people and technical backbones of enterprises will come. That is, through free innovative education and basic skills, we can quickly Education to improve the quality of citizens. I have already used various prototypes as a visitor to introduce many innovative technologies that have not yet appeared in the international market to European, American and Japanese people in English at the Shenzhen Hi-Tech Fair, a famous exhibition hall. The Science Center can also generate income by selling a full set of innovative exhibition items to domestic and foreign peers through authorization.

With the current operation method, the operating costs will of course remain high.

I already have the complete information and prototype of an exhibition item delivered to ***. Anyone in the world is welcome to imitate and improve it for free. The power supply method of this robot is an engineering structure proposed from the results of mathematical analysis. It is complete in terms of engineering application; the shortcoming is that currently only probabilistic solutions can be achieved. The audience is invited to provide pure mathematical analytical solutions in the future. At present, ordinary mathematics institutes and ordinary mathematics Ph.D.s cannot yet answer them; there are two items The exhibition items will be submitted to relevant departments for review to see if they are within confidentiality restrictions because they have innovative military uses.

Nowadays, after a college student takes an experimental class, if you block him at the door of the laboratory, borrow experimental textbooks from him, and ask him questions about the content of this tutorial, as long as the questions are accurate and detailed, they will definitely answer. When he came up, he was confused just now, and he was dumbfounded when he asked the teacher. If he was asked to make experimental equipment, he would have nothing to do with it. Today's school teaching instruments are all purchased from the public. The original manuscripts of experimental handouts are provided by teaching instrument suppliers, and the rest can be imagined. When it comes to graduate school, it is the system integration of imported software systems, hardware platforms, modules purchased on the market, and special integrated circuits and components under the guidance of original foreign scientific and technological literature and databases, scientific fast food, and a modern technology platter.

The prototype now available for free is a robot that uses its feet or wheels to obtain power from a flat surface, curved surface, or steps. It does not have to carry a power battery on its back like the Japanese Honda robot; a robotics major graduated from Tsinghua University The robot built by the doctor after working at Beijing Jiaotong University and exhibited at the Shenzhen High-Tech Fair also towed power supply cables. It was environmentally friendly and innovative. It also proposed a new method for four-wheel drive competition; the prototype provided to *** was changed to Light structure, ***** is an exhibition item of patriotism, national defense and military, and scientific popularization education; as for the basic information of equipment that surpasses foreign flight simulation training cabins and can produce controllable real acceleration, it has been notified that it is nearby It can be manufactured by any company. Based on my ignorance, I have never seen similar devices. You can also guide current students to write invention patent application documents (university intellectual property courses and patent attorneys will not teach you this!). All of these are the last word to increase ticket prices and attract audiences.

Nowadays, science and engineering students’ metalworking internships and electronic component assembly internships are all processing the same basic parts and circuit boards. After the completion, they are asked to be graded by teachers and then thrown away as waste; graduation thesis, innovative projects Etc. are all ugly and unsightly, allowing students to download materials from the Internet and imitate them; ***, we should provide practical topics for the next generation of the motherland, make full use of students' experimental and teaching funds, and I am willing to voluntarily guide them to create various A variety of innovative exhibition items guide them across the threshold of connecting book content with the market and participating in social competition.

Industrial devices and instruments made in China are basically imitated from existing products in developed countries. Simplification of the original design has problems such as redesign defects, insufficient materials, etc.; therefore, The complete solution to the faults of your exhibits often requires redesigning more complete components and remanufacturing parts. The original manufacturing department has many secrets, so it cannot be equated with repairing imported equipment. For example, the aircraft maintenance company at the airport has Boeing. The company's complete maintenance manual has very detailed written regulations for the analysis and treatment of various faults. I saw their maintenance manuals with a thickness of 5 cm prepared in rows on the way.

I have been busy working to improve my working environment for a long time, and it will come to an end in about 1 to 2 years. Before that, if you had not agreed with me to create exhibits that I designed independently, I won't be working at your place for the time being. As for any difficult questions you have, I can come and go as soon as you call. There is no guarantee that the problem can be solved. I will arrive as soon as possible. If the problem is solved, I will leave a complete electronic document explaining the procurement of materials and parts. Regarding the location and future countermeasures, we also ask that you reimburse the transportation expenses to and from the hotel.

Prepare to provide innovative exhibition items. Some basic materials are available on the CD (already sent), and the scope and fields involved will be very broad.

I recognize the method of completely free disclosure of knowledge and know-how during the Cultural Revolution, and believe that it is the most effective way to promote China's industrial base and scientific and technological level, it is the highest utilization rate of social resources, and it is an urgent need for China's national conditions of.

Some developed countries use national scientific research funds for research projects, and some relevant information is made public. For example, basic information obtained from space exploration is made public, providing an entry point for anyone around the world to conduct analysis and research. Academicians of the Chinese Academy of Sciences also signed a collective statement stating that scientific research materials should be disclosed as much as possible.

The exhibits I provide will fully disclose all design and manufacturing information, all drawings, parts procurement locations and prices, processing methods, debugging and modification processes, and computer programs. You can provide CDs to the audience and allow the audience to download these materials. Whether there is a fee, whether it is allowed to be made public on the Internet, whether you allow others to copy the exhibits and then sell or display them, whether you apply for invention patents, and whether you license domestic and foreign science popularization exhibition departments to produce and display them for a fee. Exhibition decisions are all up to you. Visitors are welcome to make suggestions for modifications. If there are any improvements after testing, you can improve the original exhibits on your own.

For the control part, try to use analog computers and discrete components as much as possible, followed by electronic circuits composed of general-purpose integrated circuits.

For the mechanical part, the cost must be budgeted in advance. If the CNC machining center is used to produce the product, the appearance and performance are good, and the price will inevitably be high. If you use electric tools to process it manually, you will have to pay for the processing cost, and the working hours are long and unnecessary. Regularity is suitable for the requirement of limiting the purchase price. It also points out that at home and abroad, the market value of devices mainly manufactured by manual processing is higher than that of devices mainly processed by machine tools and mass-produced.

I am generous enough to allow any party to use the basic design data independently proposed by me to create exhibits without any prerequisite financial requirements. Moreover, for exhibits with a manufacturing cost higher than 5,000 yuan, I will not do it if I do not have the funds accumulated from selling the exhibits. You are free to choose the manufacturing unit and individual.

We clearly know that the analog circuit design ability of students in various schools today is low, that is, some students can only write general computer programs. From analog circuits to high-frequency circuits, they can be imitated without giving the circuit; take medical electronic instruments as an example. Imported instruments mainly use discrete components for the signal processing front-end part. Domestic imitations follow the original circuits, and the performance It cannot reach the level of the original, which is a reflection of the lack of deep understanding of basic electronic circuits.

As long as undergraduates cannot debug it, the same goes for graduate students. The solution is to use special integrated circuits, imported complete machines, and system integration.

In terms of technical support, the drawings at that time were completely exchanged domestically for free, and the design drawings were copied for free among industries. At that time, unified design, large-scale cooperation, collective research, large-scale collaboration, and a nationwide game of chess were popular.

Nowadays, under the national scientific research system, there is mutual blockade, beggar-thy-neighbour behavior, and everyone in the same work unit is hostile to each other. As far as China's industrial base is concerned, under market competition, spare parts from daily necessities to industrial equipment are not universal and interchangeable; design drawings are strictly confidential, which brings great difficulties to maintenance; as a result, all enterprises have Functional products have a large number of production molds that are repeated, and parts warehouses in the production, logistics, sales and maintenance industries have large storage volumes; the result is that daily necessities and equipment are scrapped quickly, and social resources are wasted hugely.

The state invests huge amounts of education and scientific research funds in scientific research institutes and colleges and universities. However, low-level repetitive research is common, and the innovative designs of school students are basically not put to practical use. Students know how to download online, scientific and technological books cannot directly guide basic design, and teachers themselves are at a loss; some companies with strong production and design capabilities aim at market share, do not disclose technical know-how, and do not understand foreign advanced products. pose a technological threat.

Therefore, it is very necessary to make the key themes and technologies that combine basic education and production practice free to the public. This is necessary as long as it does not involve the forefront of the field or is not directly related to military technology. In order to improve the scientific quality of the whole people, this is a strategic vision and decision-making.

The ancients said: The best way to get the best is the middle way. Leading the world's scientific and technological trends is too difficult for domestic engineering and technical personnel. They are still confused and confused. They are really at a loss if they want to catch up with the world's advanced level. Leaders ask them to upgrade their products and change their product structure, but they are still tracking, imitating, and reverse engineering foreign products. Therefore, it is necessary to provide exhibits with practical value and reach the level of luxury goods; in this way, it will be forward-looking to visitors, and companies can make high-end products that enter the world market by simplifying the design.

In order to save money, electromechanical and electronic technology is the theme.
