Coquettish Rebirth

In the eyes of the old man, such a sketch by Jia Hongjian was shocking!But I have to say that this kind of astonishment is not the ugly one, nor the unacceptable one!Take a closer look, it also makes people feel a bit very special beauty!Like the position of the air intake of other suvs, Jia Hongjian designed to replace it with a metal plate.There are also ridges on the metal plate, and the primary color of the metal is intentionally made, so that people will be attracted to such a metal plate when they look at the front of the car!It can be said that from the first day of the invention of the car, since Ford developed the Model T, it is only natural that there is an air intake on the front of the car!Everyone is used to such a design, but suddenly the suv designed by Jia Hongjian has no air intake, even the position that looks like an air intake is gone at a glance, this is not involuntary Take a closer look at it?

You must know that even an electric car such as Tesla’s Highway Star still has an air intake position—because it uses the site of the Lotus sports car, and the site of others has an air intake position, so the highway When designing an electric car like Zingxing, the position of the air intake on the bumper of the sports car was made into a black depression, which makes people think it is the air intake of a sports car at a glance!So really speaking, this suv is the first car without air intakes!Moreover, Jia Hongjian designed such a design whose front is inspired by the design of fighter jets. It is really unique. In fact, the appearance design of modern cars tends to become more and more rounded.

Not just suvs, not just sports cars, all cars are becoming more and more rounded!It's like a car in the 70s. It's really horizontal and vertical, and it looks the same as Poussin.But why was it so much better in the 90s?Why after entering the new millennium.All the cars are starting to round up?Why after 2005, the transition between the luggage compartment and the passenger compartment of many sedans became more and more rounded and smooth, instead of horizontal and vertical?This is all to reduce wind resistance!It can be said that this is the result of various foreign giants beginning to apply wind tunnels to car design since the 90s!Just like a top sports car, the design is becoming more and more rounded.In the past, the design of the sports car was similar to that of the Ferrari 250gto, with a long and flat front, a suddenly rising windshield, and a slippery rear.And modern?The bottom of the car descends further.Many engines have become mid-mounted or even rear-mounted, and then the front of the car just maintains a low shape for drainage.And the design of the cockpit is to learn from fighter jets. It can be said that the whole car is equipped with various airflow guide settings!

When everyone's cars are becoming more and more rounded, the car designed by our Jia Hongjian suddenly became sharp and angular!But his sharp edges and corners are not the retro horizontal and vertical, but such a set of edges and corners made on the basis of aerodynamics, it can be said that it is moving against the trend, but it is not far from the fundamentals!Just looking at such a shape, the old man estimates that the aerodynamics will not be worse than the previous version of the plan!The edges and corners on the car or something.Even if there is no diversion effect, it looks like it has a diversion effect!

At such a time, the old man suddenly noticed such a small air deflector on the top of the back of the car. For a moment, the old man thought that such a small air deflector was a sun visor or something, but after a closer look Not like it!This thing is obviously along the back of the car, not protruding out! "Mr. Jia, what is this?" The old man asked, pointing to such a thing on the sketch. "This. This is a small deflector I designed. I don't know if it is useful. It doesn't mean that after the airflow passes through the roof, it will easily cause the boundary layer to peel off and cause eddy currents? Then design such a The deflector should allow the airflow to continue to adhere to the back of the car?" Jia Hongjian explained.

To be honest, he was a little guilty when he said this. Will the old man prove that what we designed was just a random thought?Will this thing be of no use at all?At this moment, the old man frowned slightly and stared at the sketch for a long time. "Hiss... Mr. Jia, don't tell me, this thing might be really useful!" After saying this, the old man immediately picked up the phone on his desk, and with a few words, he asked the designers from the car design team to come over.Wait until the designers come over.He immediately asked the designers to draw a formal design drawing according to Jia Hongjian's sketch, and then make a clay model according to the formal design drawing.

After giving all these instructions, the old man turned his head and looked at Jia Hongjian, "Boss Jia, if such a design can be realized, you will have made history! No one thought of doing this before!" Huh?This might work?How lucky are we?Just slapped my head and thought of a solution, it might really be useful?At this time, Jia Hongjian really felt like he had won the lottery by accident!In fact, what he didn't know was that the SUV that Lamborghini was going to build had a similar design!This Lamborghini suv is above the glass on the back of the car, and there is a small thing that looks like a sun visor across the entire glass.But such a thing is opaque, and at the same time there is really a wide gap near the roof!What is this for?Isn't it just for diversion?Isn't it a design to minimize the disadvantages of hatchbacks?

Jia Hongjian didn't know about this, but perhaps because the company has been developing automobile products these years, Jia Hongjian usually subconsciously observes pictures of vehicles or even concept cars designed by other companies. After that, he will subconsciously integrate many design concepts and techniques into Jia Hongjian's mind!It's kind of like what?It’s a bit like watching NBA players play on TV every day, and then you still want to play in NBA in the future, then you will pay attention to observe the various technical movements of NBA players, so that when you play by yourself, you will naturally know what to do. What kind of action is correct!When you see incorrect movements, you naturally feel that something is wrong!And Jia Hongjian's lucky design is actually a kind of accumulation!

But after all, can such a small thing made by Jia Hongjian stand the test of the wind tunnel?How much vortex can be optimized?As time passed day by day, the designers quickly implemented Jia Hongjian's sketches into design drawings with various data marked.It is not an easy task to turn such a sketch into a design drawing - Jia Hongjian's sketch is only roughly in proportion to each part.It is not drawn precisely in accordance with the scale, and there is no indication of the length and width of each part, so it actually becomes a design drawing, that is, the designers have to redesign a blueprint that can be produced according to Jia Hongjian's approximate shape design !Then make a model according to such a drawing, it will take several days of work!

After all, this kind of model is not made by 3D printing, it is actually made by hand - it is not very accurate.To be precise, it is the same as carving with clay. After getting a rough shape, use a carving knife or the like to remove the excess part little by little.In this way, in fact, the three-dimensional scale cannot be 100% sure that the size is completely correct, it can only be roughly accurate.Because there is no [-]D direct detection function in the game in reality, the traditional method is to measure the size of each part of the car model with a micrometer, a vernier caliper and the like, and then compare it with the proportional data!To ensure relatively more accuracy, we can only sample more points, such as ten points on each side of the whole body.But doing so can't guarantee that the entire surface completely matches the design drawing!So sending the model to the blowing tunnel is just a rough test of the concept, and in the end it is still necessary to build a prototype car and come out to blow the real car!

It can be said that it is very troublesome and cumbersome to really make a car.From a model to a prototype car, it’s not all about just making a shell, all kinds of things inside have to be added!After all, after such a car has been blown by the wind, it still needs to conduct various tests to see if there are any congenital defects in the design structure!It's like designing an airplane.Why did our country's j20 prototype appear very early, and then it has been flying for several years and has not been mass-produced?It is because the prototype has to go through continuous test flights to find all possible potential problems!Many problems are not known when the designer is designing!Just like a programmer writes code.How did the so-called bug in the code come from?Isn't it because I didn't realize that it was a bug when I coded it, and then it went wrong, so this is a bug!If it is discovered during development, how can it be called a bug?

It must be very tiring to turn Jia Hongjian's sketches into design drawings and then into models in this way.No, an American designer in the design center who had been employed for more than a year complained at this time. "This Mr. Jia is really serious. If he can draw and design everything, why do we need us? Could it be that I traveled across the ocean to work in China just to do the lowest-level drawing work for him? He didn't He has received professional training and has no more than ten years of work experience. How dare he design a car so casually? If he can do it like this, then Ford, BMW, and Mercedes-Benz don’t need to spend a lot of money to hire any design masters. Find a few middle... find a few young people to go and draw sketches!"

The American designer's name is David, who was originally a senior designer in Ford.The so-called senior means that he has worked as a car designer in Ford for more than ten years.What he does in Ford is mainly to turn the sketches designed by the chief designer into design drawings.When he was recruited by Huaxia Hi-Tech, although Huaxia Hi-Tech didn't give him the position of chief designer, he felt that it was very good.According to his thinking - China's Huaxia Automobile has only been established for a few years?I was still making cheap and messy national cars before. How many years has this lagged behind the United States?So he came to work in a Chinese company. Even if he doesn't have the position of chief designer now, who else can compete with him besides him in a few years?Those local designers in Chinese companies?

With such a thought, after he came to work in Huaxia Automobile, he would treat himself as a team leader in various workplaces!And there is also a kind of racial prejudice against Asians in the United States-whites always think that Asians are superior, but they are not good at communication, driving, fighting, lack of leadership, and tend to be quiet.White people always think that Asians are qualified and even excellent deputy, but they are definitely not good leaders!Although after David came to China, he would not foolishly talk about Asians face to face, but he always thought so in his heart.He always feels that the colleagues around him are very talkative, and they all seem to have "no leadership skills", but he feels that he has leadership skills, so in the end it is him who gives orders!He just regards the humility of the Chinese people when they meet foreigners as a kind of retreat, and regards the kindness of others as a kind of his own awesomeness!

In such a situation, when he felt that he was very good and he was the chief designer of Huaxia Automobile in the future, suddenly the boss Jia Hongjian ran over and made a mess, and then randomly designed the drawings... How could he No complaints, so how can he have no strange words? (To be continued..)
