Wang Tian tossed for most of the morning, and got a picture of the upper of his shoe size, as well as a shoe that was made and disassembled by himself.

He placed all the materials of the disassembled shoe on the ground one by one, and he needed to make a general list of materials, that is, a list of disassembled parts of a finished product.

In standardized operations, this is called BOM, a regular standard BOM, as small as a screw will be recorded, used to count the dosage, calculate the cost.

In primitive times, there was naturally no need for such finesse, but Wang Tian also had to get a general material table, about how long the rope would be needed, how much fur would be used in the upper material, and the size of the sole.

Such a general list of materials can be understood by Wang Tian, and when he thought of this problem, he felt that it was useless to make it, so he gave up this plan.

For primitive people, the number of more than 10 fingers can no longer be distinguished, and such a general table is equivalent to a book from heaven.

Although the Tianlong tribe has used Arabic numerals because of Wang Tian's arrival, it is still difficult to understand such a table, and Wang Tian intends to use the most intuitive way to preserve the information.

This method is the prototype, and in the industrial production of later generations, only those things that cannot be described will use the prototype.

For example, in order to ensure that the color of the mass-produced product is consistent with the color of the standard part at that time, a large-scale model will be retained, and the color of each batch of products in the future will be used as a reference when the mass production is made.

This sample can be a complete workpiece or a color swatch of a regular material.

Wang Tian felt that it was too complicated and unnecessary to keep a complete shoe as a model, so in order to be able to make a handshake shopkeeper earlier, he only needed to make a prototype of two workpieces.

To Wang Tian's current production of this pair of shoes to illustrate, Wang Tian is now 22 centimeters long on the sole of his feet, which is roughly equivalent to 34 yards in later generations, considering the thickness of the fluff of the animal leather shoes, plus the outer diameter of a shoe, increase by two centimeters, and make the sole according to the foot length of 24 centimeters.

When making the sole template, according to the length and width of the foot, according to the length and width of the foot, on a piece of clay with a thickness of one centimeter, cut out the template.

Then indicate 2023 on the template, indicating that this template is 20-23 cm long, and after air drying, let the sunspots be fired into a ceramic plate, so as to obtain a foot length sole sample.

Next is the expansion of the upper material, Wang Tian picked up the complete upper fur that had been cut, covered it on a large enough white paper, and first outlined the outline of the material with graphite charcoal pen on the paper.

Then use scissors to cut out the outline of the vamp, so that this paper becomes a template, but the paper is soft and fluffy, and it is not convenient to draw the line at all.

Wang Tian put this paper template on the clay again. Then cut it out with a bamboo knife and engrave 20-23 left on it.

Represents 20-23 feet long upper, the lettering is the left foot upper, after firing into a pottery plate, the engraving is pressed together with the leather bottom of the shoe, and the cut out is 20-23 feet long, and the upper of the left foot is unfolded in size.

The other side of the pottery plate without lettering is naturally the right upper, when making the upper, the side without lettering and the bottom surface of the leather are pressed together, and the cut upper is the upper of the right foot to unfold the size (the upper mold needs to dig out the hollow sole outline, which is convenient for positioning when threading after marking).

In this way, the template of the sole and the template of the upper unfolded size are obtained, and they are handed over to the sunspot to be fired into a pottery plate, and only these two templates need to be kept in the future, and the next time you make this size of shoes, you can use it directly.

The next time I make it again, I don't need to find another person to compare the prints, just pick up this sole template, and use a graphite charcoal pen to trace the size on the wood chip material used as the sole.

According to Wang Tian's design, the whole production process is as follows:

1. Carpentry group: select suitable materials to make a thickness of one centimeter of the sole plank, and hand it over to the line drawing group.

2. Draw the line group: After getting the sole plank and nitrated animal skin, use the sole template and upper to unfold the template, draw lines on the board and animal skin respectively, and the upper material distinguishes the left and right feet, and then hand over the plank to the carpentry group and the animal skin to the cutting group. (Children who work in the line drawing group can also be competent)

3. Carpentry group: Carpenter 1 cuts off the sole from the whole board with a carpentry tool stone chisel according to the marking mark on the board, and then hands it over to carpenter 2 to drill. Carpenter 2 drills out the upper leather mounting holes, as well as the tenon joints of the upper and lower soles and heels, and then hands the upper sole to the stringing group, and the lower sole and heel to the gluing group.

Meanwhile.

Cutting group: After getting the drawn line, cut it out and give it to the stringing group.

4. Stringing group: At the same time, get the sole sent by the carpentry group, as well as the animal skin sent by the cutting group, first thread the straw rope with crochet around the upper sole, and then sew the cut animal skin out of the three-dimensional shape of the upper, and then connect and lock it with a crochet needle with the upper sole according to the positioning outline above, and then hand it over to the glue group.

5. Gluing group: glue the upper sole of the upper and the lower sole of the heel installed, glue it, bind it into the bamboo tenon, and finally press the finished shoes with the glue with a stone and wait for drying.

In this way, after these 5 steps of streamlined production, a pair of shoes is completed, and each process is relatively simple, which can also be convenient for everyone to accept and learn.

If all the work is done by one person, then this person must be a generalist, who can carpenter, cut, and use crochet......

Now it is disassembled into 5 steps, and the personnel of each step are only responsible for a relatively small part of the work, so that Wang Tian only needs a simple guidance, and everyone can be competent, and some jobs can also be filled by children, which can be regarded as making full use of productivity.

In this way, the speed and efficiency will increase, and the difficulty of the work will decrease, which will create conditions for Wang Tian to be the shopkeeper.

After Wang Tian found that he had crossed over to the primitive society, he had to work hard and labor, and his quality of life was not as easy as working in the later life.

Other traversers are all kinds of awesome people who enjoy cock bombing, and they only eat salt and a seasoning food, and now they are wearing animal skin skirts, not to mention silk and satin, fragrant car beauties or something.

Under such difficult conditions, but still thinking about how to improve the level of social civilization, this is really eating chaff vegetables, and you have to the heart of the earth, one word is tired, and two words are very tired.

And Wang Tian, he is still very happy, this is not scientific, very unscientific.

According to the process envisioned by Wang Tian to make shoes, although all processes are simplified, but it still needs a general person in charge to make Wang Tian really shake the pot.

The most suitable for this job is, of course, Xiaoling, but she also has a lot of work on her hands, Wang Tian is already embarrassed to arrange another task for her, and after thinking about it for a while, he decided to hand over this glorious task to Xiaoli.

Xiaoli and Huzi were previously called by Wang Tian to work in the animal skin clothing sewing team, and they are familiar with sewing clothes and drawing threads. She is also smart and capable, and it is no problem to give her this job.

Having made up his mind, Wang Tian brought all the materials for this pair of shoes, and took some boiled fish maw glue from Zhou, and found Xiao Li, who was working in the animal skin clothing sewing team.

Then in front of Xiaoli, she made a complete set of processes for another shoe from beginning to end, and how to separate the production, and the streamlining operation was also told to her.

After that, the two collected data separately, Xiaoli was responsible for the women, and Wang Tian went to measure the size of the shoes of the men in the tribe.

He took the pair of shoes that had just been glued, went to find the size of the witch, and explained the reason to him by the way.

There is a physical object in hand, and it is easier and intuitive to explain, and by the way, I will discuss with him to kill a batch of rabbits and sheep.

Wu used to attach great importance to food, but now, now he attaches great importance to these living foods, and if Wang Tian wants to kill some, of course he has to say hello to him first.

Wu is next to the sheepfold at the moment a person is looking at the goats walking around the sheepfold Zhile, the time is close to noon, the thin head Tuo and Huzi have driven the sheep back into the sheepfold,

Wang Tian walked over and handed the shoes to Wu Yiyi and said, "Wu, I want to make this kind of shoes, I'll measure the size for you." ”

After Wang Tian finished speaking, he picked up another shoe and made a foot movement, in order to tell Wu what "shoes" is, for this new term, Wang Tian must explain it to let everyone understand.
