After a busy morning, Jiang Jixian and Lu Chengjun, the two technical bosses, finally solved all the VCD problems, and Boss Zhang and his friends happily returned to the store with the VCD.

Of course, in fact, they wanted to invite Zheng Nan and the two "masters" to dinner to thank them, but Zheng Nan did not agree, Zheng Nan came to take the opportunity to establish the concept of "after-sales"; Second, Zheng Nan really had something to meet, and Boss Zhang and they left with a pity.

The meeting was held in the store, and Zheng Nan first asked Jiang and Lu Chengjun what questions they had about VCDs.

Just kidding, whether it is Nanyan or Dongfo, they all use their own set of drawings, so the problems must be similar, which is a good opportunity for improvement.

Jiang first told Zheng Nan that basically all the problems now are focused on short circuits caused by voltage instability.

"Because VCD playback needs to limit the current pulse to a fixed range, but the voltage instability can easily cause the limiter to overload and short circuit." Jiang Ji first explained the problem to Zheng Nan in the most concise way.

The voltage is unstable, Zheng Nan is not the first time to hear it, and later generations have basically never heard of this problem, but they didn't expect the voltage problem to be so serious in this era? Moreover, from Hongqiao to the most prosperous Jiangnan Road, there is a situation of voltage instability, indicating that it is still very common.

"Such a common voltage problem, didn't VCDs be considered at the beginning of the design?" Zheng Nan asked.

Jiang Ji first replied that Zheng Nan had already considered it: "This is the reason for adding the fuse, otherwise it would not be a simple replacement of the fuse now, but the entire limiter may have to be replaced." ”

The fuse is the standard configuration in the face of overload and short circuit in this era, and it is something that every family will do in this era to change the fuse for the electric switch. Li Xing is designing a protective device for the VCD, and naturally it is just like this.

Zheng Nan shook his head: "But this doesn't work, we can't ask customers to replace the fuse, and they don't understand, it can only mean that there is a problem with our design." ”

Speaking of which, it seems very simple to replace the fuse, but in fact, because the VCD is a new product, coupled with the confusing circuit added by Zheng Nan to prevent imitation, etc., even the top engineers of Nanyan Dongfo can't figure out the internal structure.

Therefore, they don't know what your fuse is short-circuited, they only know that your product will break within a few days of buying it!

Zheng Nan is very glad that he has collected information about the problem through after-sales, if this problem is left unchecked for a while, it will only cause public resentment to boil.

Zheng Nam asked if there was any way to solve the problem.

Jiang Ji thought about it first and replied to Zheng Nan: "This problem should be solved through an external transformer." ”

This answer reminded Zheng Nan that in his later life, when he used a laptop, or charged an important electrical appliance such as a mobile phone, he would basically bring a transformer connector, thinking that there would be voltage instability that would cause damage to delicate components, and he avoided it in advance.

Zheng Nan nodded in approval of the solution through the transformer, but Zheng Nan also asked, "Is there a way to change the transformer to a built-in one?" This makes the product easier to use. ”

Jiang first said that the working principle of the transformer is more complicated, unless it is specially customized, the volume of the transformer is too large, and the VCD cannot maintain a slender volume. In addition, the transformer should not only consider high voltage and low voltage, but also consider heat dissipation, so the built-in transformer is definitely not as good as the external effect.

At the same time, Zheng Nan also called back to Jiangxia Electronics Factory and told the old factory director to urgently purchase additional transformers in Jiangxia, so that the transformer would become the standard configuration of VCD in the future.

After calling his own people, Zheng Nan thought about it, and still called Wang Guohua and Manager Sun, and shared with them the VCD problem he found.

"That's it, we found that many VCDs on the market are damaged due to voltage instability, so I suggest that you also urgently equip customers with transformers to minimize the probability of VCD problems."

Zheng Nan also reminded emphatically: "You must keep this issue a secret and must not spread it." ”

Zheng Nan reminded him that these old foxes still didn't understand what was going on, they were obviously digging a pit and waiting for Dongfang Audio to jump.

Everyone knows that Dongfang Audio is now copying its own VCD, and even borrowing heavily to do it, so if you don't do something, wouldn't it be interesting?

Zheng Nan also said: "Of course, this problem is that we have not considered the technical design, so as to make up for it, you can send all the VCDs that have problems to me for repair, and I will only charge a nominal repair fee, and not only the voltage problem, but any other VCD failure, can be sent to me." ”

Wang Guohua and Manager Sun all said yes, just kidding, although they have no after-sales awareness, but they also understand that VCD, as a new product, must be broken and difficult to find a place to repair, plus Zheng Nan took the initiative to call, proving that this hidden danger is still relatively large, if you let things go, it will not work.

Now that Zheng Nan is willing to take over this burden, how can they be unhappy?

Of course, they didn't think about what Zheng Nan's purpose was to take the initiative to take this burden, but thinking about it, it didn't hurt them, and they could still help them take over the trouble, so why not?

Hanging up the phone, Jiang Jixian also asked questions, not understanding why Zheng Nan did this: "I know that Director Zheng is a responsible person, but doesn't this make our branch in Ninghai a repair shop?" ”

Zheng Nan told Jiang Yixian with a smile that this is a good move for Dongfang Electronics to make a sign.

First of all, they were supposed to establish an after-sales system, but now there is not enough manpower, and the temporary recruits have no technology and no experience.

And then most importantly, every time they give customers a repair, they will emphasize the after-sales service of Dongfang Electronics.

"Director Jiang, you think, every time you come to repair with other brands, you have to charge money, and when you see Dongfang Electronics' products, they are repaired for free, and this kind of differential treatment will implant them with a kind of Dongfang Electronics' products over time, which is better than others and more secure, and can invisibly have the opportunity to pull other people's customers to our side."

"Even if we can't monetize it in a short period of time, at least we can make them remember the brand of Dongfang Electronics, which is very beneficial for our future expansion."

Zheng Nan said: In short, now is to get the manpower up as soon as possible.

Jiang Ji first told Zheng Nan that he left a few people in the interview yesterday, and he would bring them out of the division as soon as possible with Lu Chengjun.
