After Li Rujin returned to the research institute, he plunged into the research and development work, the research institute is still a little deserted, no longer the excitement of the day, due to the shortage of funds, many projects have to suspend research and development, but several more important projects are still retained.

Such as engines, communication systems, etc. The engine is still limited by material problems, and there is not much progress, but the research and development work has not stopped, and the new engine model is constantly being built and theoretical research is carried out.

Li Rujin believes that as long as the material problem is solved, the technology of the engine of the Dawen Empire will definitely have a qualitative leap.

The research and development of the communication system is even more surprising to Li Rujin, the research and development results far beyond Li Rujin's expectations, the battlefield communication equipment has begun to miniaturization, portable development, although there are still some difficulties, but obviously, the research and development personnel have mastered the pulse of the battlefield, you know, if the soldier is equipped with a single soldier communication system, what a huge improvement in combat effectiveness.

Li Rujin carefully understood the research and development progress of the individual soldier communication system, the finished product, the research and development team has already made, the volume is still a little large, the communication range is okay, has reached a distance of 25 kilometers, but the battlefield adaptability is obviously not enough.

After all, the environment on the battlefield is complex and changeable, and communication equipment must not only ensure the quality of communication, but also be dustproof, waterproof, and shockproof, which are the most basic three defenses. In addition, it is necessary to think about the confidentiality of communications, the prevention of interference, and the ease of maintenance on the battlefield.

Thinking of ease of maintenance, Li Rujin thought of plug-and-play general standard accessories, this is a big killer, the part is broken, just replace it, save maintenance time, and ensure smooth communication.

After Li Rujin said this idea, it was affirmed by the R&D team, Li Rujin and the R&D team had a short meeting, and then began the modular design of communication equipment.

In the previous life of the earth, when it comes to plug-and-play general standard parts, the most successful application is not the computer, whether it is the motherboard, CPU, memory module, or even the power supply, chassis, and interface, all of which are standardized universal accessories, which have too much experience to learn from.

Under the leadership of Li Rujin, the entire R&D team did not spend too much time to complete the standardized design of communication equipment, Li Rujin picked up the design drawings and looked at them carefully and made some changes, mainly to reserve some space and interfaces, and prepare for the future upgrading of communication equipment.

Then the design drawings will be formally finalized, and Li Rujin will not ask about the production of parts, and when the formal products are produced, they will be reviewed by Li Rujin, and if there is no problem, they can be mass-produced.

In another office of the communication research and development team, Li Rujin found several semi-finished products of electric fans, at first, Li Rujin was a staff member doing private work, and only after listening to the staff's explanation did he know that this was a mobile portable fan developed for the soldiers of the Dawen Empire on expeditions to Africa.

Although it is rare for the jungle area to have a high temperature of 38 degrees, 39 degrees or even more than 40 degrees, the perennial temperature is also above 30 degrees, and the body is sweaty every day, which is extremely uncomfortable.

In addition, the labor intensity of soldiers is high, and they either perform military tasks or train every day, and the consumption of physical strength can be imagined, and if they do not sleep well at night, the impact on soldiers will affect the combat effectiveness of soldiers.

Some time ago, when the soldiers of the expedition to Africa came to customize the communication facilities, they inadvertently talked about the hot climate in Africa to these staff, and these staff members were attentive and prepared to develop a portable mobile fan suitable for the African climate. It can also be regarded as a small effort for the soldiers of the Dawen Empire who are on an expedition to Africa.

Li Rujin expressed his admiration and sigh for the noble character of the scientists of the Dawen Empire, these selfless scientists can reflect the noble character through some small events, which Li Rujin is really ashamed of, you must know that Li Rujin once served as the supreme commander of the African Expeditionary Force.

Li Rujin picked up a semi-finished product and studied it, and then the staff next to him also came over to explain the design ideas of the fan to Li Rujin, there is no problem with the idea, the power supply relies on the advanced battery technology of the Dawen Empire, and the power supply is mainly based on the battery, which is convenient to move.

Portability can also be seen,In order to reduce weight,The fan blades are made very thin,The shell of the fuselage is also made of extremely thin iron sheet,Many functions have been canceled or reduced,For example, the shaking head function has been canceled,The gear is only designed with three gears,Cancel the on/off key,Directly use the gear to control the switch。

The workmanship is not even said, it can be described as exquisite.

After Li Rujin watched the fan, there are some aspects that are worthy of praise, and there are some aspects that Li Rujin doesn't want to complain, these scientists have never been to the battlefield, they have never been to Africa, they just want to do their best to make a beautiful fan, but it is not suitable for the battlefield.

Li Rujin first affirmed the idea of portable mobile fans, although this small idea is simple, but the market prospect is extremely broad, not only for the soldiers on the expedition to Africa, but also for the development of civilian versions, to the Dawen Empire market.

Then, in a tactful way, the shortcomings of this fan can be found out one by one, such as materials, which can be made of plastic, the bracket can be made into a liftable type, and the power supply and circuit interface inside can be made into standard universal connectors.

The whole fan can also be made into a splicing type, a part of the fan head, a part of the bracket, and a part of the base, which are spliced together when in use, and disassembled when not in use to reduce the volume, and then specially made a bag for holding.

These scientists admired Li Rujin's almost whimsical ideas, a small fan, which can contain so many technologies, has been played by Li Rujin.

But this is not the end, Li Rujin continued to open his mind, and developed a set of supporting equipment, such as solar panels, which can charge the battery when there is no fixed power supply, and a tripod can set up the fan head when the ground is uneven.

These supporting equipment may not be suitable for Africa, but they can be suitable for the market of the Dawen Empire and increase the added value of the product. With a small fan, he gave a vivid academic extension lesson to the scientists of the Dawen Empire.

These scientists are completely convinced, this person, whether you are smart or a genius, you can't compare with demons! Li Rujin's continuous expansion of his brain hole is also profound, although it is only a temporary idea, but the effect seems to be not bad.

The scientists of the Dawen Empire have no academic attainments in themselves, but they have obvious deficiencies in academic derivation.

Immersing oneself in research every day has, to a certain extent, imprisoned the expansiveness of these scientists' thinking.
