"Two years, more than 700 days. I broke my leg in order to produce a sample of this Huafeng phone." Zeng Liqing sighed.

"In the past two years, I have always been forced to become an expert in the mobile phone industry."

Rosa deeply feels the same. It is different from industries such as design and software.

The physical industry has more processes and is very complicated.

Huafeng Company has a total of six basic departments: ID, g and QA.

The first is industrial design (ID), including the appearance, feel, material, and color matching of the mobile phone. The visible and tangible parts on the mobile phone all belong to the category of design, such as metal or plastic in the frame, whether the back is curved or faced, which colors to use to match, etc.

The first thing to consider in industrial design is visual effects, and its quality directly affects whether a mobile phone is beautiful and classic. After the product is launched, industrial designers began to have various imaginative ideas, and even took turns to brainstorm, and it was not impossible to repaint hundreds of sketches.

Because some works are too advanced, they can only be kept in the designers' computers. After the final plan is finalized, if you want to realize it, you have to rely on the next structural designer.

If industrial design pursues the effect of visual sensitization, then structural design (MD) is a way to truly restore this effect.

After the ID design determines the appearance of the phone, MD    step by step to build all the spare parts inside the phone.

For example, if it is made into one or the rear cover, the frame is made of metal or plastic, how to fix the rear case on the frame, how to place the battery, whether the motherboard grows squarely, whether the screen is fully fitted or framed, etc.

There is also the size control of all parts. This is like building a house. The ID completes the main frame of the house, and the MD renovates the interior of the house, and then enriches the furniture.

While there is still time.

Zeng Liqing was very happy to tell Xu Youyu about the hardships of mobile phone design and manufacturing.

Let him learn more about his products and add some confidence to negotiate with Apple.

"...These are the two most difficult departments in the front line. Fortunately, the chief designer Rosa is responsible for it. With her design drawings, we only took 90% of the detours. Both good starts are half the success, and half of the achievements made by Huafeng Company are from Miss Rosa."

Zeng Liqing praised Rosa without hesitation.

Xu Youyu is undoubtedly a genius, a genius in the Department of Mathematics of Fudan.

but.

He is good at data processing and has a developed left brain.

Those who need to develop the right brain are confused about what design beauty is.

This is also the reason why he makes a joke when he takes a plane.

Xu Youyu looked at her for more than ten years.

And this beautiful woman, Rosa, has just graduated.

But the achievements in design are by no means inferior to those of you.

After Ye Feng showed him the samples of his smartphone, he knew that as long as this product could be produced normally, it would definitely become a hit.

The industrial aesthetic of design.

He, who doesn't know how to design, praised him very much.

One word, absolutely!

"Mr. Zeng, Huafeng Company has you at the helm, and Miss Luo's outstanding design talent, the future is limitless."

Xu Youyu said: "Sun Tzu's Art of War says: Know yourself and your enemy, and you will never be defeated in a hundred battles. Please continue to tell me about the process of Huafeng Company designing a smartphone. Only if I understand and understand clearly can I get more favorable conditions in negotiations with Apple."

"Okay. There is a cafe here, so why not sit in and chat while drinking."

Zeng Liqing invited Xu Youyu and Rosa to the cafe and continued to talk about his hard work in Huafeng Company over the past two years.

"After industrial design and structural design, it is hardware design (HW). The hardware mainly designs circuits and antennas to realize the configuration requirements of mobile phones..."

Zeng Liqing told me in a casual manner.

In order to give Xu Youyu a more intuitive understanding.

He also turned on his laptop and called out the information to show Xu Youyu.

The circuit part of the mobile phone is first made of an enlarged PCB motherboard based on the configuration parameters, and various debugging is performed. After the solution is feasible, it will be condensed to make the mobile phone motherboard.

The design of the motherboard is divided into single-sided layout and double-sided layout. Single-sided layout means that all parts on the motherboard are arranged on one side and there are no parts on the back; the double-sided layout has parts on both sides, and the motherboard with double-sided layout will be thicker than the single-sided layout, but the area of ​​the single-sided motherboard will be larger than that of the double-sided.

To use a single-sided or double-sided motherboard, it depends on how the structure is designed. Therefore, the process of hardware design (HW) design is also a process of negotiating with structural design (MD).

In the domestic PCB motherboard printing business, many manufacturers in Shenzhen Stock Exchange have international standards.

However, the motherboard requirements of Huafeng mobile phones are so high that Zeng Liqing searched all the companies in Shenzhen Stock Exchange and finally found a veteran PCB company, Shennan Circuit, to assist in completing it.

"There is another important part of hardware design, which is antenna design. Mobile phones support more and more frequency bands, especially the upcoming data era such as 2G and 3G. The more antenna design tests the wisdom and experience of hardware design engineers. The antenna must be far away from the battery, and there cannot be metallic devices nearby. It can be said that in order to take into account the design of the antenna, both industrial design and structural design must make way for the antenna."

"I have been searching for this antenna across the country for three months, but I didn't find a manufacturer, so I finally had to go to Dongyang to customize it."

Zeng Liqing felt bitter and lamented that there were too many gaps in domestic industrial levels.

"The next software design (SW) is even more difficult. Between the motherboard hardware and the operating system, there is another software called BSP, which is a board-level support package, which can also be said to be part of the operating system. The main purpose is to support the operating system and enable it to run better on the hardware motherboard. This small software run by hundreds of engineers from Huafeng Company took a whole year to complete the test."

"Software Design (SW) is a bottomless project. The hardware part may be completed in one go. However, software development must continue to develop new functions, fix bugs, improve stability, and develop new functions... Such an infinite cycle process."

"The so-called smartphones should not only be reflected in the strength of hardware configuration, but also require software creativity to implement more functions. The various affinity interfaces and thoughtful functions designed by Rosa must be completed by software design. Software design also needs to maximize the potential of existing hardware, which is also the greatness of software design."

Zeng Liqing himself worked on software at Tencent.

But he was asked to create a smartphone operating system. Sorry, he doesn't have that much ability.

Fortunately, he knows many engineers.

With the method of not spending money and noting life, Huafeng Company personally served as chief engineer, gathering the collective wisdom of hundreds of software engineers.

Finally, a mobile phone operating system of Huafeng Company was developed.

This system is based on LINUX. Although it is simple, it can really make the phone run.

"Look."

Zeng Liqing used a computer to demonstrate to Xu Youyu, and then said:

"This operating system called Huafeng 1.0 can only barely run. There are many bugs and obvious lags. I guess it will take another year or two to improve it. The software system is indeed our shortcoming."

"What, you have developed an operating system?"

Xu Youyu was surprised and said, "This is an operating system. Although it is used on mobile phones, it can also be used on electronic products such as gaming consoles, tablets, and handheld computers. Think about Microsoft. A system dominates the world and gives Bill Gates the position of the world's richest man. I have to re-evaluate the value of Huafeng mobile phones."

"Actually, this is one of the reasons why Mr. Ye made us contact Apple."

Zeng Li Qingyouyou said: "Apple has been founded for nearly 20 years and its operating system has been well received. And it is not like Microsoft is the world's number one, and it is disdainful to cooperate with us. Apple is more likely to reach a cooperation with them."

Xu Youyu nodded in agreement.

Next, Zeng Liqing introduced the project management (PM) and quality supervision (QA) processes in smartphone design.

"In mobile phone production, is this design feasible and how is the quality reliability? Every innovation needs to be tested and reviewed by QA. If it is found that the production is too difficult and the yield rate is low or the test cannot be passed, then this plan will be rejected. Unconventional tests such as bending tests, drop tests, etc. In short, producing a mobile phone is not as simple as doing experiments in the laboratory. Once it is produced, there are thousands of them. It is not easy to ensure the quality of each product. It is completely different to produce a sample of a mobile phone and producing 100,000 mobile phones."

Zeng Liqing pointed to his Huafeng mobile phone and said:

"The process of making a mobile phone is simply divided into these six major directions, and the complexity is not something that ordinary people can imagine. Fortunately, Mr. Ye only asked me to produce samples first. Teacher Xu, the mobile phones you see are all laboratory products. Look at this screen, this chip, and this memory are all collected by me who traveled all over the East, South Korea and North America. If it is mass-produced, the cost of this will be sky-high, and our millions of mobile phones will be more than one billion US dollars."

Zeng Liqing said heavily: "So, we must use external forces to improve our smartphone products."
