Reborn Troops

Zhou Wanwan was sitting in her small jewelry shop in the old town. The leaves of the sycamore trees outside the window were swaying in the autumn breeze, and the sunlight was shining through the window onto her workbench.

Her fingers gently stroked a piece of fine steel, and designs appeared in her mind.

"Wanwan, the atmosphere in your store is really relaxing." Qianqian sat on a wooden chair beside her, holding a cup of freshly brewed green tea in her hand, blowing the hot steam gently.

"Yes, this is my favorite place. Every time I sit here, I can find new inspiration." Zhou Wanwan smiled, her eyes still on the fine steel in her hand.

Qianqian put down the teacup, walked to Zhou Wanwan, and looked at the fine steel in her hand. "What are you going to do this time?"

"I want to design a ring that is simple yet unique." Zhou Wanwan said, the fine steel in her hand flashing a cold light in the sun.

"Simple yet unique, that's not easy." Qianqian raised her eyebrows, as if thinking about something.

"It's indeed not easy, but I believe I can do it." Zhou Wanwan said confidently, with a determined light flashing in her eyes.

"Wanwan, are you really planning to make that kind of bracelet?" My best friend's voice came from the door. She walked into the store with a cup of hot coffee in her hand.

Zhou Wanwan looked up, a smile on her lips: "Yeah, don't you think this is a good idea? It's both beautiful and practical."

Qianqian sat opposite her and took a sip of coffee: "It's a good idea, but how can you ensure that it is both beautiful and can be used as a lock?"

"This is the problem I want to solve." Zhou Wanwan's eyes flashed with a challenging light, "I already have a preliminary design, but I still need your help to make it more attractive."

Qianqian put down the coffee cup and looked at Zhou Wanwan seriously: "Okay, I'll help you. But you have to treat me to a good meal."

The two began their cooperation. Zhou Wanwan was responsible for the structure and function design of the bracelet, while Qianqian was responsible for the beautification of the appearance.

They worked hard in the store for a few days and finally made the first sample.

The bracelet is made of fine steel, with a simple yet stylish look, and the chain is inlaid with a few tiny gemstones, which add to the beauty without affecting its function as a lock.

Zhou Wanwan buckled the bracelet on the electric bike and tried to pull it, but the bracelet didn't move at all.

"It looks good." Qianqian praised, "But we need more people to test its practicality."

Zhou Wanwan nodded: "I have contacted several regular customers, and they will come to the store to try it out tomorrow."

The next day, several customers arrived as scheduled. They praised the appearance of the bracelet, but encountered problems in actual use.

Although the bracelet is sturdy, it is not convenient enough to unlock the door, and some customers are even unable to complete the unlocking action.

Zhou Wanwan and Qianqian looked at each other, they realized that there were still flaws in the design.

"We need to reconsider the unlocking mechanism." Zhou Wanwan frowned and said, "This may take some time."

Qianqian patted her shoulder: "Don't worry, we'll take it slow."

In the next few days, the two of them devoted themselves to the design again.

They tried a variety of unlocking mechanisms, from simple buttons to complex combination locks, but could not find a perfect solution.

Zhou Wanwan and Qianqian sat in the corner of the jewelry store, with various tools and materials in front of them.

Their brows were furrowed, obviously troubled by the unlocking mechanism of the bracelet.

"Should we consider electronic locks?" Qianqian suddenly suggested, "With the advanced technology nowadays, electronic locks are both safe and convenient."

Zhou Wanwan shook her head. "Electronic locks are too expensive and difficult to maintain. We need a simple, reliable solution."

Just then, an old customer came in. He was a retired engineer who was quite knowledgeable about mechanical structures.

"Old Li, you're here just in time!" Zhou Wanwan's eyes lit up. "We are worried about the unlocking mechanism of the bracelet. Do you have any good suggestions?"

Lao Li walked to the workbench, carefully observed the structure of the bracelet, and then said, "Why don't you try the gear transmission? Unlocking by turning the gears is both simple and reliable."

Zhou Wanwan and Qianqian seemed to see a ray of hope. They immediately started to redesign the bracelet according to Lao Li's suggestions.

After several days of hard work, the new bracelet sample was finally completed.

This time, the bracelet not only looks more refined, but also has a more convenient unlocking mechanism. Zhou Wanwan buckled the bracelet on the battery car and gently turned the gear, and the bracelet was easily unlocked.

"Great!" Qianqian said excitedly, "There will definitely be no problem this time."

Under the warm lights of the jewelry store, Zhou Wanwan and Qianqian's faces were filled with the joy of success.

Their new bracelet samples not only solved the previous problem, but also unexpectedly attracted more customers' attention.

However, just as they were preparing to bring the bracelet to market, an unexpected problem arose.

"Wanwan, look at this gear, it seems a little loose." Qianqian frowned and pointed at the key component on the bracelet.

Zhou Wanwan took the bracelet and examined it carefully, her expression gradually becoming serious: "Indeed, if this problem is not solved, the durability of the bracelet will be greatly reduced."

As the two were discussing solutions, the wind chimes at the door of the store rang again, and this time a young mechanical designer named Xiao Zhang came in. He was Lao Li's apprentice and had unique insights into precision machinery.

"Xiao Zhang, you're here at the right time. We've encountered a difficult problem." Zhou Wanwan hurriedly called him over.

Xiao Zhang took the bracelet, observed it carefully, and then made a bold suggestion: "Why not try using high-precision ceramic gears? They are not only wear-resistant but also lightweight, which can effectively reduce the problem of loosening."

Zhou Wanwan and Qianqian looked at each other and saw hope in each other's eyes.

They decided to adopt Xiao Zhang's suggestion and immediately started looking for a suitable ceramic gear supplier.

After some effort, they finally found a reputable supplier and quickly ordered a batch of ceramic gears.

However, just as they were preparing to remake the bracelet, the supplier suddenly sent a message that the delivery of the ceramic gears would be delayed due to production problems.

"What should we do?" Qianqian said anxiously, "Our new product launch will be next week. If we can't finish it on time, all our efforts will be in vain."

Zhou Wanwan clenched her fists and took a deep breath: "We can't just sit there and wait for death, we must find a way."

At this time, Lao Li appeared in the store again. He heard about their predicament and proposed a temporary solution: "We can use the existing metal gears first and reinforce the structure to ensure that the bracelet can be used normally before the ceramic gears arrive."

Zhou Wanwan and Qianqian took action immediately. They worked overtime and made emergency modifications to the bracelet.

After a night of hard work, the bracelet finally reached an acceptable standard.

On the day of the new product launch, the bracelet won the favor of many customers with its unique design and convenient unlocking mechanism…
