MTL - The Black Tech Life of Scum-Chapter 255 : Junk products
In the past, because of improvement while developing, Zhang Yifan did not follow up very much after changing the stereotypes, so he didn't feel it yet;
This time, he really realized how fast the national machine reacted when it moved;
And this is just a resource used by a small research institute, and China has a large number of similar institutions;
It is not difficult to imagine how the world ’s largest country on the other side of the ocean 70 or 80 years ago, after the outbreak of the war, how to build warships and aircraft carriers like dumplings, is a resource of the entire country. ...
Soon, the first prototype of the mass production type ground machine was assembled. Even if Zhang Yifan repeatedly reduced weight, the main structure was made of high-strength aluminum alloy, and the titanium alloy was used for part of the joint and moving parts;
With the battery and the fuel tank full of oil, without any load, the weight of the single machine has reached 20 kg;
After a trial run, expert Li applauded them. In their opinion, this is already very good!
However, this is still not ideal in Zhang Yifan's view, because it is very difficult for a person with limited mobility, or an elderly person, to move a forty-pound object;
Moreover, because the engine and battery are fixed, this walking machine takes up too much space, there is no way to fold it, and it takes up space when idle;
Now that there is no way to compress the space and reduce the weight, Zhang Yifan thought of a new way: modular combination.
"Zhang Gong, do you think this works?" Expert Li looked at the prototype machine that Zhang Yifan had broken up and asked with a beard.
"Why not? This battery pack plus the motor is ten pounds heavy. The diesel fuel tank is heavier. Usually, it only uses one of the power. The extra will increase the loss," Zhang Yifan said.
"But do you think he can be disassembled like you by ordinary people?" The director of the institute on the side was also puzzled.
"Of course you ca n’t do it so early. You also need to add a power transfer device. In this case, you need to install the electric drive module if you want to use electricity, and install the fuel module if you want to use diesel. These modules can also be used for other purposes when the aircraft is flying, "Zhang Yifan said.
"What is it for?" Expert Li was curious.
"First of all, this electric module contains a motor, which can output power. The pump connected to the corresponding interface is a water pump, and it can also be connected to a blower. The battery is connected to the inverter, and it can directly output small power. Electricity, wherever electricity is not available, can be used to illuminate anything; "
"Not to mention the fuel, as long as the matching power output interface is achieved, it can be directly converted into small agricultural machinery;"
"Crazy? Thousands of dollars can get things, you have to use these nearly 100,000 dollars to get it?" Expert Li said lamely.
"You can't say that. For example, it sells a hundred thousand and two hundred thousand cars, is it expensive? You can't say that the tripod or jack in it is expensive?" Zhang Yifan said.
"The ground moving machine is expensive in its power transmission, walking and balance system. Then the battery and motor are just like the high-power point electric car. How expensive can it be? Moreover, I do this modularly, mainly to reduce weight. All are incidental! "
"This makes sense, otherwise I said that all people who use walking machines are disabled people, and you want them to make agricultural machinery, which is too unreliable." Expert Li said.
"Who says disabled people can't go to the ground?" Zhang Yifan said resolutely.
Expert Li was anxious. He was afraid of Zhang Yifan's mess, and he said quickly: "Don't mess around with messy things, get them out quickly, and reduce the cost as much as possible. Do what you said before."
"Rest assured, I'm not so indifferent, but this modularity is also related to reducing costs," Zhang Yifan laughed. "For example, some users just want to travel short distances and do not need diesel power. It is not necessary to buy this module, which is equivalent to saving thousands of dollars. "
"I also reduced some configurations as much as possible. For example, the front and rear luggage racks are completely unnecessary for short trips, so I only kept a cup holder. I also reduced the laser insecticide. I also used the automatic walker. Minus ... "
"The automatic gearbox and walking balance mechanism should be able to drop a bit after mass production. If you buy the lowest version, it is estimated that you can get it for less than 50,000 yuan," Zhang Yifan said with a mobile phone. Well, the result is given.
"Change the material of the main body to steel. The Bluetooth speaker should be reduced. There is no need for a sunshade. Then the material of the seat back is not so good. Canvas can be used. If necessary, Users can install it themselves, "said expert Li, pointing to a pile of parts on the ground;
"Mr. Li, these are small things that can't save a few bucks. Let ’s just say that the Bluetooth speaker is only a few tens of dollars, and there are a few pipes that are shaded. If we buy a large amount, a car also "Twenty or thirty dollars, just the ones you said, you can't save three or five hundred dollars," Zhang Yifan said.
"It's my hand, can't I know?" Expert Li paused, then said in a deep voice: "Zhang Gong, you are too young, you don't understand."
"Why don't I understand?" Zhang Yifan asked.
"As a disabled person, it is a burden in the home itself, and it is a burden. The family not only spends on them, but also takes time and care to take care of them. Such a family, even if it is slightly better, will be exhausted Come down; "
"The price of the walking machine is originally expensive. Although some families can now afford it with gnashing their teeth, the resources at home will also be inclined. There are places where money is used. Children need money to read, pensioners, and doctors. It costs money for everything, it's too expensive, and I can only give up with pain; "
"Disabled, can not create any value in themselves, enjoyment is already a luxury for them, as long as they can allow their family members to spend less energy on them and allow them to go out without relying on others, then It's already the biggest enjoyment, "Li expert said earnestly.
"That's it," Zhang Yifan lost in thought.
In Nali Village, although it is small, it has also seen various aspects of life.
How can relatives and neighbors help each other and still have their own family life, the Li Bing family is a good example;
Li Bing is a good girl in the flowering season. She should have gone to high school and entered a university like everyone else;
Even if you can't pass the exam, go out to work and earn some money, then fall in love and marry someone and live a life of husband and wife;
This is a very ordinary life, but just because of my grandmother's illness, what is it like being dragged down stiffly?
I ca n’t read the book, I ca n’t go to work, I can only nest in the corner of the mountain, and then even the blind date fails several times ...
Ask yourself, if you do n’t have them, even if the walking machine sells for about 50,000 yuan, can Li Bing afford them?
And how many families like Li Bing are in the country?
"Xiaofan, your generation is born in a good time. Think of our era when eating bowls of white rice was as happy as the holiday season. When I was a kid, I once saw someone starve to death beside me; eating meat In the army, eating meat and drinking, that is to go to the battlefield, even the steel helmets are not well matched, "Expert Li said again.
"Like people of our generation, I have n’t seen anything, I ca n’t eat any bitterness? What kind of comfort, pull the ball, if I do n’t have my legs, you will be the one who will make me fart, as long as you can make myself People go out and I recognize it! It's better than staying quietly at home waiting for someone to take care of, okay? "
"I told you something two years ago. I and two old comrades met to see our squad leader. He was injured on the battlefield and his legs were blown off. Fortunately, the family took care of him. On the day of my appointment to meet him, we did not tell him in advance; "
"When I arrived at his house, I realized that his family was dispatched, and looked for him everywhere, and finally found him in the adjacent village. It was a few kilometers of mountain road. Normal people have to walk for more than an hour. He The door was opened before daylight, and it took five or six minutes to walk. When we saw him, the skin in his hand was worn out, and even one hand was bloody, but hehe ... ... "
"What do you think this is a picture? You're all like this, can't you stay at home?" Expert Li said with a sneer: "Yes, yes, from the perspective of others, this is all right. Now that you have difficulty moving, stay home and don't bother your family, don't you? "
"But who thought about the monitor's point of view, what did he think, what did he want to do? Stay in the room every day, and then watch the TV waiting for dinner, waiting for the old, waiting to die? He really doesn't have his own idea, He wanted to go out and see what was wrong? Who ever thought about it? "Expert Li was obviously a bit angry when he said this.
Once upon a time, life became so humble because they lost their ability to live.
"If there is a tool that can help him go out, don't say that there is no such thing as your stereo, even if it is no longer comfortable, no matter how dangerous it is?"
"You are alive, and never look at others by your own standards. Maybe you feel shabby driving a 100,000 yuan car, but at the same time, others may not have a bike."
"Then Li, what do you think of me?" Zhang Yifan asked. This time he asked it sincerely, with knowledge or a sense of awe.
"Reducing costs desperately and doing everything you can to keep costs to a minimum, people will buy high-end things, no matter how expensive they are. "Expert Li said.
"Okay, just do what you say!" Zhang Yifan thought about it and said.
——————,
Expert Li and Zhang Yifan have not had much contact time. If it is Wang Beibei, then it is another matter;
He will never think of what it would be like to be desperate in the eyes of Zhang Yifan;
When suggesting to reduce costs, Expert Li dare not touch those core things, because he can't figure it out by himself;
Therefore, I can only get started on peripherals and peripherals. I find it useless and remove what should be removed. The only idea is to allow more people to use this cheap auxiliary machinery;
Including Zhang Yifan's idea of giving two kinds of power to modularization and letting users make choices, this idea is also tacitly accepted by experts Li, because it can really reduce a lot of costs;
However, he did not consider how to return if an electric-powered ground machine was de-energized;
This is not a wheeled machine, but a machine driven by six feet. It is impossible to push it by humans, or to lift the machine back;
Either you can only take the battery back to charge it and then install it, or bring a fully charged battery over and install it.
And to reduce costs at all costs, in Zhang Yifan's eyes, it is more than just modular power;
Zhang Yifan moved, it was really distraught to reduce costs;
Intelligent automatic gearbox changed from eight-speed to three-speed, with fewer gears and two-thirds fewer moving parts;
This is the lowest configuration that Zhang Yifan's existing ability can achieve. First gear, perform tasks such as climbing and obstacle crossing;
Second gear ~ www.novelbuddy.com ~ is some less steep terrain, which can speed up some speed.
The third gear can only adapt to a relatively flat ground, and the speed will be faster. Of course, the master control is still in the hands of the operating crew.
Many shortcomings have also been exposed. First of all, when traveling, there is no way to keep stable and shake all the way;
Then there is a clear sense of frustration when switching between grades, and there is no buffer when accelerating. In short, it can create a feeling of full back ...
There are also some safety devices, such as the rear radar, which was cancelled because Zhang Yifan felt that this walking machine does not normally reverse, and that the speed is twice as slow as usual when traveling backwards, so that it can run into that. No harm can be done.
And those reversing radars cost a lot of money ...
Then, continue to reduce, and the photography of the middle side is also canceled. It is not necessary to keep it, but it costs money. If you want to touch porcelain, it should be on the front side.
Such a set of Zhang Yifan's magic reforms were all reduced, and using a computer, it cost less than 10,000 yuan ...
It is just too weak compared to before the cost reduction;
The power can only be electric, and then it is the kind that charges for ten hours and drives for one hour;
Then, when I walked, I was okay when I went up and down the stairs ...
There are basically no electronic devices, just a wheelchair that can be used to control walking, and that's it!
To act at night, then flash a flashlight yourself;
If you want to travel on a rainy day, make an umbrella yourself;
Even Zhang Yifan himself couldn't bear to look directly at this product from his own hands;
It's too garbage!
