"Modularity means that we don't think about the complexities first. In the past, when we produced this pulley crossbow, we used one person to produce it from start to finish, and every part was produced by almost the same person. And our modularization, in fact, means that we do not consider the gradual production of individual parts, but make an overall plan before production. We've just worked out the means of weights and measures, and I think with your technology, it won't take you a few days to get used to it. And what we need to do next is to disassemble this complex bow and crossbow. ”

Chen Fei is teaching craftsmen, and now Chen Fei is also preparing to explain the concept of so-called modular manufacturing to these craftsmen. Chen Fei's modularization, in fact, is to imitate a concept of later generations, by gradually decomposing a complex thing, and finally not considering the step-by-step production, but the whole first. And after having a general framework, the connection parts of the different parts were examined. To use the analogy of later generations, there are different subsidiaries, and these subsidiaries do not interact with each other, but there is a group company above them as a channel for them to communicate. As long as this continuous channel is not interrupted, they will work perfectly. Therefore, before designing and manufacturing, the first thing to consider is the connection between their different modules, and how to make them use it perfectly.

And this is the skeleton that has been designed, and finally more people can fill the flesh and blood inside. Since then, this design pattern can make a complex tool gradually simpler. In this way, at most, it is to find a senior craftsman designer, plan an overall skeleton, and finally it can be completed by those designers with poor skills, so that it is a modular design.

Chen Fei first had to break down the drawings of this pulley bow and crossbow step by step, and then told the craftsmen the key points they could produce. Chen Fei requires that the connection parts between different modules have the highest precision requirements. Because if the accuracy of this place is not high enough, the final result is that it cannot be connected.

Chen Fei designed this pulley crossbow in the hope that their parts could be used interchangeably. These pulley crossbows are all designed to the same standard. Then later the soldier can use it on the battlefield. Even if one part is broken, you can remove the next part from another broken pulley crossbow and replace it with a new one.

This reduces a lot of production costs and improves utilization. In the past, after a crossbow fired dozens of arrows, it was often discarded by the soldiers, or damaged for some reason, or simply forced to discard because the soldiers were injured and killed. And in this case, the weapons are almost completely lost, because they cannot be used. But now Chen Fei has adopted a modular design. In this way, even if a bow and crossbow are broken, they can be replaced with a part of another bow and crossbow, so that they can be used universally. For the recovery function of weapons and equipment, there are great benefits. If two bows and crossbows are broken together, the loss is only two, and now it is possible to reassemble the intact parts of the two bows and crossbows into one crossbow, which is equivalent to the loss of one bow and crossbow. If the number increases to tens of thousands, the larger the final scale, the less the relative loss. It is of great help to the country to reduce the losses caused by the wear and tear of equipment.

And even if one part is broken, it is completely possible to produce only one part in the rear, without having to produce the entire crossbow machine. Whether it is transportation or production, it is a great savings.

"Have you figured it out? Who is responsible for manufacturing which part? You can consider according to your skill level. Divide into several groups. Then the task is implemented step by step, and finally it is divided into details for each person. Finally, according to the uniform standard, the parts are manufactured and then assembled by a responsible assembly team. This speed can be much faster, and it would have been a crossbow machine. Now it is able to produce more than a dozen units. Isn't it a lot faster? Chen Fei asked.

And that Yang San immediately said: "Chen Langzhong is really a genius, no, a ghost talent!" Follow this method. It means that the number of people has not increased, but the speed of manufacturing has increased by more than ten times. And in this way, we can supply countless troops of our Datang Dynasty with a small number of manpower. ”

Yang San was really convinced by Chen Fei, Chen Fei had only been here for a few days, and he was able to formulate this set of methods, and this assembly line production method had a lot of benefits. Not only is the production speed much faster, but it can also save costs. First of all, the labor cost is also a huge advantage, after all, there were few craftsmen in the Tang Dynasty, and the price if you want to hire craftsmen is not low. Spending the salary of one craftsman now is equivalent to being able to recruit a dozen craftsmen in the past, which is of course satisfying.

Originally, Yang San thought that Chen Fei was a layman, after all, Chen Fei was admitted to the Ming Jing exam. The people who obtained the official position in the Ming Jing examination were actually not too valued in this era. In the early Tang Dynasty, the most important thing was Xiucai, but Xiucai was the most difficult to examine, and it was even later abolished because it was too difficult. The second is the Jinshi Branch, and finally the Ming Jing Branch. But Chen Fei, who went up to the Ming Jing exam, was actually very proficient in all aspects. From that time, the development of people's livelihood in Shuo County was enough to increase the population like a snowball. Later, when he came to Bozhou, Chen Fei withdrew from several new policies in Bozhou, which made the Datang Center follow suit.

Now that I'm here as a Kurabe Langzhong, I've only been thinking of a good way to improve my work efficiency in just a few days. This is simply a ghost, and genius is not enough to describe Chen Fei. Yang San was also completely convinced of his boss. Chen Fei is not a layman in anything, and he has a great future!

"Chen Langzhong, now the manufacturing efficiency is enough to increase more than ten times, then we may be able to complete the task before the imperial court regulations!" Yang San said.

But Chen Fei immediately said: "This is not enough, we are only able to produce crossbow machines, but there are still many raw materials for processing, and there is no way to solve it!" For example, wood, wooden shafts of various arrows, and arrowhead grinding are all very complicated, so the next thing we need to do is to find a way to increase this speed. If we can't produce enough crossbows, we won't be able to produce bows and crossbows! (To be continued......)
