Reborn Troops

"Little girl, your idea is quite novel." Old Li said with a smile.

Zhou Wanwan nodded, "Yes, I want the windmill on the roof to rotate, and the decorative effect will be better."

Lao Li looked at the design and frowned, "This design is a bit complicated.

The blades of the windmill must be light, otherwise the roof will not be able to bear it. Also, the bearings must be installed inside the roof, otherwise it will affect the appearance of the car."

Zhou Wanwan nodded, "Yes, I have also considered these issues. Do you think it can be achieved?"

Lao Li pondered for a moment and said, "You can try, but it will take some time. You have to give me a few days and I will study it."

Zhou Wanwan said gratefully, "Thank you, Master Li. I'll wait for your good news."

A few days later, Lao Li called and told Zhou Wanwan that the design had been completed.

She excitedly rushed to the modification shop and saw that a small windmill had been installed on the roof of the car, with the blades turning gently in the breeze.

"That's great!" Zhou Wanwan said excitedly.

Lao Li smiled and said, "Little girl, your idea is good. However, I have to remind you,

If the windmill turns too fast, it may affect the stability of the car. You have to pay attention to the speed of the car."

Zhou Wanwan nodded, "Thank you, Master Li. I will pay attention."

She was driving, and the windmill on the roof was turning slowly, attracting the attention of passers-by.

Zhou Wanwan felt a sense of accomplishment. She knew that this design would definitely become the highlight of her jewelry store.

However, just as she was immersed in the joy of success, an accident happened.

One day, Zhou Wanwan drove to pick up Qianqian, and the windmill on the roof of the car was spinning very fast.

Suddenly, a strong wind blew, the windmill blades accelerated suddenly, and a harsh friction sound came from the roof.

"Wanwan, there seems to be something wrong with the windmill!" Qianqian said nervously.

Zhou Wanwan also felt something was wrong and quickly stopped the car on the side of the road. She got out of the car and found that the bearings of the windmill were loose and the blades were shaky.

"Oh no, we have to fix it quickly." Zhou Wanwan said anxiously.

She got out her tools and tried to fix the bearings, but the windmill's blades were deformed beyond repair.

Zhou Wanwan stood beside the car, holding the deformed windmill blade in her hand, her brows furrowed. Qianqian stood beside her, looking at her with some concern.

"Wanwan, how about... let's take down the windmill first? It's too dangerous to drive like this." Qianqian said softly.

Zhou Wanwan sighed and nodded, "You're right, I was too impatient. The design of the windmill is not perfect yet and needs to be readjusted."

Just as she was about to dismantle the windmill, her cell phone rang. It was her younger brother Zhou Guo.

"Sister, where are you? I just passed by your jewelry store and found that you were not there." Zhou Guo's voice came from the other end of the phone.

"I'm outside. There was a problem with the windmill on the car." Zhou Wanwan said somewhat frustratedly.

"Windmill? What windmill?" Zhou Guo asked curiously.

Zhou Wanwan simply told Zhou Guo what happened. There was silence on the other end of the phone for a few seconds, and then Zhou Guo laughed.

"Sister, your idea is quite interesting, but the design of the windmill does have some problems. How about I help you redesign it?"

"You?" Zhou Wanwan was a little surprised. "Aren't you studying computer science? How come you can design a windmill?"

"Sister, don't underestimate me." Zhou Guo said proudly, "I studied mechanical design.

Although it's just an elective course, I can still help you fix a small windmill."

Zhou Wanwan hesitated for a moment, but finally agreed, "Okay, then come and help me take a look."

After hanging up the phone, Zhou Wanwan and Qianqian dismantled the windmill together, and then drove back to the jewelry store. Not long after, Zhou Guo also arrived.

"Sister, where is the design drawing of your windmill? Let me see it." Zhou Guo went straight to the point as soon as he entered the door.

Zhou Wanwan handed him the design. Zhou Guo looked at it carefully and frowned slightly.

"Sister, the blades of your windmill are too heavy, and the position of the bearings is not reasonable.

When the wind blows, the blades rotate too fast and the bearings cannot bear the pressure, so they become loose. "

"What should we do then?" Zhou Wanwan asked anxiously.

"Don't worry, I have a solution." Zhou Guo smiled, took out a laptop from his bag, and started drawing a new design on it.

Qianqian leaned over to take a look out of curiosity, "Zhou Guo, what are you drawing?"

"I'm redesigning the structure of the windmill." Zhou Guo explained as he drew, "First, the material of the blades must be changed to something lighter, such as carbon fiber.

Secondly, the bearings had to be redesigned to include a speed limiter to prevent the blades from spinning too fast.”

Zhou Wanwan nodded repeatedly, "What about the load-bearing problem of the roof?"

"This is easy." Zhou Guo pointed to the design on the screen, "We can make the base of the windmill detachable.

It can be removed when not in use to reduce the burden on the roof. In addition, the base material must be replaced with a lighter aluminum alloy. "

Zhou Wanwan looked at Zhou Guo's design drawings, with a hint of surprise in her eyes, "Guoguo, you are so amazing! Why didn't I think of this?"

Zhou Guo smiled proudly, "Sister, you are usually too busy and don't have time to study these details.

However, the design is only the first step. The next step is to find a professional manufacturer to customize the parts.”

"Then let's go now!" Zhou Wanwan said impatiently.

Zhou Guo nodded, "Okay, but I have to remind you that it may take a few days to customize the parts, so you have to be patient."

"No problem!" Zhou Wanwan said confidently.

In the next few days, Zhou Wanwan and Zhou Guo went to several factories together and finally found a suitable manufacturer to customize the windmill parts. A few days later, the parts were delivered to the jewelry store.

"Sister, the parts have arrived, let's start assembling!" Zhou Guo said excitedly.

Zhou Wanwan nodded, and the two began to assemble the windmill according to the new design. Qianqian also helped, handing over tools from time to time.

"This bearing has to be installed here, and the speed limiter has to be fixed on the base." Zhou Guo explained while assembling.

Zhou Wanwan listened carefully, her hands busy. After several hours of hard work, the new windmill was finally assembled.

"Okay, let's give it a try!" Zhou Guo placed the windmill by the window. The breeze blew gently, and the blades slowly turned.

"Success!" Zhou Wanwan said excitedly.

Qianqian also laughed, "Zhou Guo, you are so amazing!"

Zhou Guo smiled proudly, "Sister, you can rest assured now. The new windmill is not only lighter, but the speed limiter can also ensure that the blades will not rotate too fast."

Zhou Wanwan nodded, "Thank you, Guoguo. If it weren't for you, I really don't know what to do."

Zhou Guo waved her hand, "Sister, why are you being so polite to me? But you have to drive carefully next time and don't damage the windmill again."

Zhou Wanwan smiled and nodded, "Don't worry, I will pay attention."

A few days later, Zhou Wanwan installed the windmill on the roof again. This time, the blades of the windmill turned gently in the breeze, which was both beautiful and stable.

"Wanwan, your car is so cool!" Qianqian sat in the passenger seat, looking at the windmill on the roof, and couldn't help but exclaim in admiration.

Zhou Wanwan smiled and said, "Yes, this design is finally successful."
