In March, Musk, who was reeling from the new crown epidemic, was accurately cued by a tweet from the mayor of New York City, who said he was a Tesla owner and loved the company, so Tesla should go ahead and make respirators ......The logic is pretty awesome when you think about it ......
What could Musk say? Say yes, of course. And claimed that Tesla cars have air conditioning systems, Space?X? has life support systems, since you Dyson can rely on vacuum cleaner technology to build a respirator, then I rely on air conditioning systems to build a respirator seems to be no problem, are all air exchange.
Of course, compared to Ford and GM, which were named by the president, Tesla was only named by the mayor, and its burden seems to be lighter.
Subsequently, the melon crowd found that Musk imported a number of respirators from China ......
Well, just as the domestic melon crowd laughed at Musk's bragging, but in the end, it is still necessary to rely on China, and the evil of capitalism will not work in the critical moment, Tesla released another video to prove that they are using the Model?3? parts to develop a respirator!
The whiteboard shown in the video shows a drawing of the system structure of this ventilator, with Tesla's car parts in orange, medical parts in blue, and other parts in gray. At least judging by this diagram, Tesla and the ventilator have a pretty good ****ing use of parts.
We discern from the video that this ventilator's mixer, mainframe, heater, monitor, and other parts are using Tesla cars.
One video at a time, it seems like this Tesla ventilator is pretty decent.
At this point, some publicists are going to fire: "Tesla can make a respirator, why don't Chinese car companies go and build one?" "Chinese car companies will make masks this kind of non-technical things, high-tech will not be ......"
Saying this kind of thing is really ...... line, today will be a simple Say why it is so difficult for car companies to build respirators.
■? Building a respirator is really hard hard hard hard!
This is the Baidu encyclopedia on the composition of the respirator map, look quite simple, but in fact not so much!
First look at the hardware, according to the microblogging @ Explain X-PLAN video shows that the ventilator needs the following hardware:
Microcomputers suitable for medical equipment, high-precision pressure sensors, air mixers, solenoid valves, compressors, medical pressure detector ......
Even if these hardware can be solved through suppliers, or even with the ones on the car, it is important to realize that the most critical parts of the ventilator are the following two.
Let's look at the interpretation of the professionals, according to the legend of the Zhihu netizen, the legal representative of the medical device company @ respiratory craftsman: the core of the respirator is the motor and the underlying algorithms, and these two things happen to be the medical device manufacturer's watchdog, all of which are closed source; similar to Tesla's own AP and FSD, which are very difficult for laymen to get.
Next is the algorithm, I believe that Tesla himself is also clear in his own heart, his own AP and FSD powerful in the complex algorithms and the ability to continue to iterate, so as to realize the unique NOA.
Ventilator is also the same, how to realize the pressure switching? How to build an accurate flow control system? How to raise and lower the pressure according to the patient's degree of obstruction and airflow?
In addition to this, professional manufacturers with years of experience in the production of medical devices can also accurately combat the new crown pneumonia, such as the domestic brand of ventilators, Yuyue, has chipped in more than 7,000 sets of non-invasive ventilators to Hubei, and made a lot of optimization in response to the outbreak, for example, making the ventilator more targeted to the new crown patients, to better ensure that the equipment is stable under high-pressure use, and to optimize algorithms based on the large number of outbreaks of clinical data. Based on the optimization of the algorithm, which is not something that car companies can learn in a short period of time.
Yuyue said it could take as many as 40 days to produce a single ventilator, even in a state where they have increased capacity several times for the epidemic, the specialty medical device maker.
In summary, producing a ventilator is a lot of pressure on hardware, software, technology, and time, not unlike producing a mask.
■? U.S. hospitals received Tesla's ventilator?
An overseas netizen picture, the U.S. hospital received a Tesla logo hanging respirator, but also wrote a special "THANK?YOU?TESLA" slogan to express gratitude.
That's pretty awesome, isn't it? A video of a self-developed ventilator posted on YouTube, and then a ventilator in the hands of frontline healthcare workers?
Just as the special blow began to climax, a witty netizen realized that the ventilator was a Tyco PB840......
I also found Tyco's PB840 on the Internet, and the comparison did look similar.
And there was also previous news that Tesla would follow up with a medical device maker like Medtronic to produce a ventilator.
But, as the netizen said, Tesla is definitely not just assembling the ventilator and labeling it, it should have systematically learned the technical standards of production and assembly, in order to send the "Tesla brand" ventilator to the front line. After all, human life is at stake, not sloppy.
■? The company's main business is the production of respirators, which are made by Chinese automobile companies.
Think about the domestic car companies turn to the production of masks when? Is the outbreak of the epidemic, mask companies to resume work is difficult, the national simply can not buy masks time. Now the domestic epidemic has stabilized, Hubei gradually resumed work, Wuhan is about to usher in the unblocking; domestic medical equipment manufacturers can basically meet the domestic demand, and even can also receive orders from abroad, or humanitarian assistance, therefore, there is no need to let the car enterprises at this time to turn to learn the high cost of learning, industry barriers are high, and their own is not yet good at the field. Besides, they haven't been selling well these past few months, so it's better to let them produce a few cars first.
In fact, whether it is the U.S. Tesla, Ford and General Motors; domestic BYD or Wuling and Guangzhou Automobile, as the "lifeblood of the national economy," they are in the country when they need to head up. From ancient times to the present, car companies from building shells and airplanes to masks respirators snail powder, "what the people need, Wuling what to build" this sentence is definitely not a slogan, the world's car companies are doing their best to contribute to their motherland, this attitude and spirit of each industry, each company, and even each person is worth learning.
