1991 Starting from the core

"Let's change it a bit. Which is more important, your mold or my function?"

"No, if you lay it out like this, wouldn't it be a big deal? Is it difficult to change the lines? Now your PCBs are still engineering boards, which are as big as a palm. Is it difficult to make them smaller?"

"Isn't it difficult? Come on, you can do it, come on!"

"I can get in, do I still need you?"

…

It only took a few dozen seconds from the time Su Yuanshan and Wang Rui opened the door to the two people who were arguing to find them, and the two of them started talking back and forth like a cockfight, hundreds of words.

Seeing Su Yuanshan and Wang Rui, they both closed their mouths at the same time.

Wang Rui glanced at Su Yuanshan and said with a smile: "Don't worry, continue."

As he spoke, Wang Rui introduced Su Yuanshan: "These two are the director of the design center, Zhu Yuanxin. The other one is..."

"Wu Siguo." Su Yuanshan said the name without waiting for Wang Rui's introduction.

Wu Siguo is the designer led by Tian Yaoming, that is to say, the one who "changed the feathers".

The two quickly faced Su Yuanshan.

At the same time, the designers behind also lowered their heads and began to pretend to be busy with their work.

Su Yuanshan said with a smile: "Let's go to the conference room to continue."

Zhu Yuanxin: "..."

Wu Siguo: "..."

Entering the conference room, Su Yuanshan smiled at the two of them and said, "Brother Zhu, can you take a look at your current mold? Do you have a 3D drawing?"

"have."

Zhu Yuanxin switched jobs from the Design Institute to Yuanxin Design Center last year. He graduated from the Central Academy of Design and received a master's degree in industrial design. Less than half a year after joining Yuexin, they redesigned a VCD mold. Although it was still square, the edges and corners were eliminated, and the entire body was oval. Although it was still not as good as Sony's sci-fi design, it was better than Sony's sci-fi design. The original one looked much better.

As Zhu Yuanxin spoke, he pulled out a design draft from the filing cabinet next to him and unfolded it: "In order to take care of the PCB board, we have modified a lot of details. It was originally a beautiful mobile communication device, but they suddenly said it was not working here and not there. no……"

Wu Siguo glanced at him and didn't want to refute, but when Su Yuanshan nodded repeatedly, he immediately said: "No, if you are doing appearance design and don't consider the layout of parts and just make it look good, then just find someone who can draw." Wouldn’t it be possible to become a designer?”

"Stop!" Wang Rui immediately raised his hand: "You two, give me some face."

Su Yuanshan smiled and shook his head.

Although he only designs chips at HiSilicon, he often hears conflicts between appearance and technology - the design of mobile phones was initially led by engineers, that is, the internal structure layout was given priority, and the appearance mold was matched. However, with the increasing aesthetic demands of users, the design led by engineers has gradually fallen out of fashion and has become a priority for appearance. In other words, engineers match the appearance.

This is somewhat similar to the requirements and front-end in program development.

One wants to look good, the other wants to save trouble - this contradiction is basically class opposition and cannot be reconciled.

However, the birth of any excellent product is the mutual understanding and compromise of appearance and structure.

It's really not okay to be tit-for-tat like this...

The two stopped arguing, and then looked at Su Yuanshan at the same time, waiting for his decision.

After pondering for a few seconds, Su Yuanshan smiled and said slowly: "Any excellent product is inseparable from the stability of its structure and function. But it is also inseparable from its good-looking appearance. Sony's VCD at the beginning killed our VCD instantly. Zha is a very simple example."

“So I tend to think that after designers design the products they have in mind, engineers need to cooperate with them as much as possible - when it is really impossible to complete the requirements, or it is extremely difficult to cooperate, and the gains outweigh the losses, the designers will make adjustments and compromises. .”

"Senior Brother Wu, whether the structural layout is reasonable and whether every inch of available space is utilized is the biggest test of an engineer's ability."

Wu Siguo opened his mouth and looked at Su Yuanshan in surprise. But when he saw Su Yuanshan's determined expression, he quickly realized that Su Yuanshan did think so.

As an old employee of Yuanxin, Wu Siguo knew that whenever Su Yuanshan was determined about something... it would be difficult for him to be wrong.

So he was silent for a few seconds and nodded: "Then let's see if we can modify it - the main reason is that the baseband chip has been taped out successfully. If we make major changes to the PCB, it may take a long time. We don’t know whether it will be stable in the future. Furthermore, if the modification increases the difficulty of the project, the yield rate will not increase, and the output will not increase either... then the gain outweighs the loss."

"Yes, what you said makes sense." Su Yuanshan nodded: "But I took a look and found that the shape of the PCB is still a standard rectangle - in fact, we can consider making a special-shaped PCB. There are gaps in some places, such as On the top, you can reserve the earpiece and position, and on the bottom, you can leave a gap for the motor, etc."

Su Yuanshan pointed to the PCB pattern on the drawing and said with a smile: "If these parts are arranged separately, it means a lot of space will be wasted... and the mold will be enlarged. In my opinion, every inch of space in a mobile phone should be precious." "

"That's so right!" Zhu Yuanxin's eyes lit up and he couldn't help but praise: "This kind of handheld device will definitely become smaller and smaller, and space will become more and more precious."

Wu Siguo sighed softly, this guy really knows how to climb along the pole.

"Haha, Brother Wu, don't sigh, it's true - because the appearance represents the user-oriented, and the mobile phone is a typical mass consumer product. It is not like an experimental instrument. As long as it can be used, it doesn't matter whether it is stupid, bulky or not."

Wu Siguo nodded: "Yes, I understand."

"Okay, let's go and see it together."

Su Yuanshan said, seeing Wu Siguo putting away the drawings and about to put them back in the filing cabinet, he immediately said: "By the way, we will establish a strict confidentiality system from now on. The products under design, whether they are paper drawings or software documents, are absolutely It’s not allowed to be revealed.”

"Once illegally disclosed, Yuanxin will be held accountable in accordance with relevant regulations."

Although Wu Siguo was still a little depressed because Su Yuanshan "helped the designer" speak, his depression disappeared when Su Yuanshan agreed to stay and modify the design with him.

Everyone knows that Su Yuanshan's design level is amazing.

It's just that... Su Yuanshan didn't touch the circuit of the mobile communication department for two years, no matter how magical he was, he couldn't do it.

He had never studied mobile phone wiring in its infancy.

But he knows that nowadays, the internal space of a mobile phone is more watery than a sponge, and you can squeeze out some space just by squeezing it.

Moreover, Zhu Yuanxin also reflected on himself and took the initiative to find Wu Siguo to see if he could first fix the microphones, earpieces, motors and other big things that take up space without changing the current appearance, and then see how to adjust the various interfaces. s position.

Three days later, Chen Jing and Tian Yaoming returned with the authorization contract between them.
