When Lin Zhenhua returned to Xunyang from Shanghai, he began to arrange the follow-up design and production of the waterfall washing machine.

The development of a new product does not happen overnight, and there are many steps to go through from an idea to the final product.

The first step in the development of new products is the design of the principle, and Lin Zhenhua entrusted Liu Xianghai's unit to do such a thing. Through theoretical analysis and practical simulation, Chang Qingbo et al. confirmed that the waterfall spray method has a good washing effect, and gave the data of the location of the water nozzle, the water flow intensity, and the intermittent water spray, which solved the problem of principle.

The next step is to translate the principle into a drawing. For example, how a water spraying device should be realized mechanically requires precision to how each pipe is bent, how each valve is controlled, and all the parts must be finally implemented on the drawing.

In addition to the shape on the drawing, the designer needs to determine the various aspects of each part, such as how much pressure the pipe needs to bear, and how many times a valve needs to be opened and closed repeatedly without damage.

Lin Zhenhua basically handed over the work of mechanical design to the teachers and students of the Department of Mechanical Engineering of Huaqing University. Whether it's a work-study program or a professional internship, in short, Lin Zhenhua unceremoniously tied them to his chariot. Teachers and students are also very interested in this work, after all, it is much more interesting to design a product that can bring economic benefits, which is much more interesting than talking on paper in school.

Lin Zhenhua also borrowed several technicians from Hanhua Machinery Factory to assist in the work, and the main products of Hanhua Machinery Factory include vacuum pumps, centrifugal pumps, etc., and the core component of the waterfall washing machine is the water pump used to generate water flow. The principle between the pump and the pump is the same, so the rich experience of the technicians in the Hanhua factory is very useful in this matter.

With the design drawings, there is still some distance from putting into production, and the process engineer has to implement the production process of each part, including what kind of steel to use, what kind of machining method to use, what kind of heat treatment, and so on. After these problems are solved, the engineer can hand over the drawings and process documents to the workshop director, so that they can organize the workers to carry out production.

In terms of process design, Lang Dong took on all the technical teams of Xunzi. The production of bicycles also involves a series of processes such as machining, heat treatment, and painting, so Xunzi's technical team is no stranger to technology, and Lang Dong is also eager to let the power of Xunzi play a role in the development of Hanhua Company.

Lin Zhenhua's own profession is also mechanical, and he has a certain understanding of all stages from design to production, and he personally serves as the person in charge of the entire design and development work, accompanying the technicians to catch up with the progress day and night.

Of course, it is unrealistic to expect Lin Zhenhua to draw drawings in person, he generally just participates in discussions, and then gives everyone some words of encouragement, and then bears the material conditions such as bonuses and housing. He unceremoniously stole the quotations of the chief designer and pasted the words "science and technology are the primary productive forces" on the wall of the laboratory, which moved the intellectuals who had been stinky for several years to tears, and almost wanted to repay Lin Zhenhua's kindness with death.

The design of the waterfall washing machine lasted more than three months, during which several key technologies were developed. Lin Zhenhua did not hesitate to hand over all these technologies to Qian Yuanping and asked him to apply for patents in various countries. With these patents, the production of waterfall washing machines is all controlled by Lin Zhenhua, who wants to imitate this idea to produce similar washing machines, will encounter many patent barriers. The keys through these barriers are all controlled by Lin Zhenhua.

"Okay, now you can send a notice to the home appliance manufacturers in various provinces, telling them that the waterfall washing machine has been successfully developed, and if you want to make this money, you should pay the patent fee first." Lin Zhenhua said with a smile to the people in his team.

Patents are not granted so quickly, but as long as the patent application is accepted by the patent offices of each country, the technology is considered protected. Lin Zhenhua can't wait for the time when the patent is approved, which will take a year or two. Time is money, and Lin Zhenhua can't watch the silver flow away from his eyes.

Lin Zhenhua has a $500,000 patent fund specially approved by Gao Zuxing. Before he left Guangzhou, he had already told Schumann to set up a patent agency in Guangzhou, hired Qian Yuanping as the director, and also brought in several patent agents from Hong Kong to be responsible for the application of various patents. Qian Yuanping saw a huge undertaking in Lin Zhenhua's description, and if Lin Zhenhua's patent fund idea could be successful, the patent firm would have to undertake tens of thousands of patent applications in the future, which was enough to surpass any similar law firm in Hong Kong.

"Xiaohua, how much is the appropriate royalty we charge?" Peng Shaozhe asked.

Lin Zhenhua counted with his fingers and said, "At least, a washing machine is calculated at 20 dollars." We can sell a washing machine for about $200, and we charge them one-tenth as a royalty, which is really not a lot. ”

"Okay, I'll just contact them like that."

"Don't worry, there is another point, all manufacturers who want to produce waterfall washing machines must first make a deposit of 500,000 yuan, and then we can give authorization. These deposits are non-refundable and can be used to offset royalties in the future. Lin Zhenhua came up with another trick. He is in a hurry to use the money now, so he can collect some margin and come back first, which can also relieve the financial pressure.

"Manager Lin, I can see with my own eyes how you robbed the money." Lang Dong sighed, "If this kind of washing machine can sell 1 million units to the European and American markets, you will have 20 million in patent fees alone." How much does it cost you? ”

Lin Zhenhua said: "This is called a trick of freshness, eat all over the world." They didn't expect to use their external brains to engage in development, and I thought that of course they could make a lot of money. ”

The external brain that Lin Zhenhua said naturally refers to Liu Xianghai's propeller institute and the mechanical department of Huaqing University, which are China's top research institutions. If the transaction is carried out according to the true value of technology, Lin Zhenhuaguang will have to pay tens of millions of yuan to invite these people to engage in design. But now, he only gave Liu Xianghai 500,000 yuan, and the money he gave to Huaqing University was even more pitiful, and the teachers and students couldn't get the most 1,000 yuan, followed by some transportation expenses, meal expenses, and so on.

Even with such a pitiful reward, the teachers and students of Huaqing University already felt very uneasy. After all, the teachers' annual salary is only six or seven hundred yuan, and now they get thousands of yuan after working for a month or two, will the school interfere? Does the system allow it? Everyone stuffed the money into their pockets with trepidation, but they all had happy smiles on their faces.

"Our Hanhua company's products should form an echelon. The fan is an obsolete product that will be thinner and thinner, but it should still be able to generate cash flow for the company for a few years. The waterfall washing machine is an emerging product, and I plan to launch it at this year's autumn fair, with a sales target of 300,000 units, and I will earn back $60 million first. In the next two years, the waterfall laundry machine will be our main product. Lin Zhenhua planned.

"What about our bikes?" Lang Dong is most concerned about this issue.

Lin Zhenhua said: "The bicycle can be our next generation product, this product does not have too many skills in terms of design, the key is to solve the process problem. My plan is that the launch of the sport bike is set for the spring of 1985, which is still nearly two years away. ”

Lang Dong said: "Manager Lin, don't worry, I am willing to make a military order." ”

Just when Lin Zhenhua was intensively arranging the production of washing machines, the leaders of Hanhua Machinery Factory were also racking their brains to enter the home appliance industry. After collective discussion, everyone decided to take the refrigerator as the main product of Hanhua Machinery Factory in the future.

Medium-sized machinery enterprises like Hanhua Machinery Factory faced great embarrassment back then. The predecessor of Hanhua Machinery Factory was only a chemical equipment parts enterprise with a small scale. In the era when the whole country was vigorously engaged in "preparing for war and preparing for famine," all localities were vying to pursue an industrial pattern of "large and comprehensive" and "small and comprehensive," and every county was building small chemical fertilizer factories, small agricultural machinery factories, small textile factories, and other small enterprises, and they were eager to extract oil from under their feet.

It is said that this self-supporting industrial layout is designed to enable each county to become a self-sufficient base area for the war of resistance behind enemy lines in the event of a full-scale imperialist invasion. I don't know if the leaders at all levels at that time had read too many time-traveling novels, and would have fantasized about building a county-based industrial system with complete reading power under modern conditions.

Small fertilizer factories, small phosphate fertilizer factories and small pesticide factories have blossomed everywhere, creating a series of medium-sized machinery enterprises such as Hanhua Machinery Factory. In those days, the business of the Hanhua factory was not worried, and just providing equipment for the fertilizer factories in 100 counties of the province was enough for the Hanhua factory to be busy.

After the reform and opening up, the state has carried out large-scale industrial restructuring and gradually eliminated backward production capacity. Taking the fertilizer industry as an example, the state began to restrict the development of small fertilizer plants, and introduced several sets of large fertilizer equipment from abroad to replace traditional fertilizer production. The production capacity of chemical fertilizers has increased significantly, while the demand for fertilizer equipment has decreased sharply.

In this case, the survival of a series of enterprises such as Hanhua Machinery Factory is highlighted. Hanhua Machinery Factory won a set of large fertilizer equipment from Guixi Fertilizer Factory last year and made a lot of money. But since the beginning of this year, there have been no new orders, and the workshop has been in a state of semi-shutdown.

The leaders of the factory found their counterparts from all over the country and inquired around, and found that the Hanhua factory was not the only company in distress, so they realized that the situation was not good, and if they did not quickly change production, they would only become more and more sad. Nowadays, the most profitable is light industrial products, so Hanhua Machinery Factory decided to start a refrigerator.

Zhu Tiejun made a phone call to Lin Zhenhua and asked him to rush to Fenghua immediately to discuss how to persuade the Light Chemical Department to approve the introduction of a refrigerator production line at Hanhua Machinery Factory.
