"I feel like this helmet feels different; it's much lighter than before."
Upon hearing this, everyone subconsciously weighed the safety helmets in their hands.
"You know what, it really does seem to have lost a lot of weight!"
They used to go to construction sites often, and every time they came back, their necks would be sore and painful.
They weren't used to wearing them even after only a few hours.
It's easy to imagine how much those workers disliked hard hats.
Then some observant people noticed that the helmets they received were significantly lighter than before.
The internal structure also seems to be quite different.
Inside each helmet, a cross-shaped suspension system is made using canvas straps and rivets.
Seeing this, Chris complained to Chi Heng, "This helmet is so light, can it even provide any protection?"
Professor Li happened to be nearby and, upon hearing this, smiled and offered an explanation.
"You don't need to worry about safety; we've already conducted experiments."
"Don't underestimate these few canvas straps inside. If something hits the cap shell..."
"This cross suspension system provides excellent cushioning, which is much more effective than simply adding a thicker helmet!"
Upon hearing that experiments had been conducted and that an expert like Professor Li had personally vouched for it, everyone felt relieved and happily put on their safety helmets.
"Who came up with such a great idea?"
Just then, several deans who were acquainted with Professor Li said something in a half-joking manner.
"Old Li, why didn't you tell us sooner!"
"We only just got it recently," Professor Li said, adding with considerable pride, "This idea was actually Xiao Jiang's!"
Upon hearing this, Chi Heng paused slightly.
"Little Jiang?" Which Little Jiang?
"Which Jiang could it be?" Realizing what was happening, Professor Li pointed to Jiang Si, who was standing not far away.
"This was Engineer Jiang's idea?" Everyone was even more surprised now.
"yes."
Seeing their incredulous expressions, Professor Li simply recounted how Jiang Si had approached him two months prior to discuss improving the safety helmet.
He only gave a general outline; the specific details would have to be provided by Jiang Si.
Everyone has already put on their helmets.
Jiang Si then used this topic to officially begin today's visit.
A large portion of the delegation originally came with the intention of finding fault or just watching the spectacle.
Unexpectedly, as soon as they entered, everyone's attention was drawn to this unassuming safety helmet.
Seeing this, Jiang Si briefly explained her improvement ideas.
In fact, the materials used to make safety helmets in later generations are basically high-density HDPE or ABS engineering plastics.
However, the technology and craftsmanship of that era could not achieve that level.
So she came up with an improved method.
The method is actually quite simple: add some chopped cotton fibers or wood pulp fibers to the raw materials used to make the helmet.
Of course, these cannot compare to the effect of glass fiber.
However, glass fibers are typically used in military and aerospace applications, and the raw materials are not readily available.
As for the function of the cross-shaped cushioning straps inside, Professor Li has already explained it, so Jiang Si didn't waste everyone's time.
It is emphasized that the improved safety helmet, while ensuring comfort, can maximize the personal safety of workers.
There were also many foreign guests present today, and although they didn't understand what Jiang Si was saying at the time.
But her confidence, composure, and unhurried professionalism still drew gasps of admiration from everyone.
Especially after hearing the translators' explanation, everyone looked at Jiang Si with more appreciation and respect.
Chris didn't speak, her mind preoccupied with what she had overheard in the state-run store.
Without realizing it, she glanced at Chi Heng beside her.
Chi Heng was facing away from her at that moment, so she couldn't see the expression on his face.
But she was certain that from the moment they arrived until now, Chi Heng's gaze had remained fixed on Jiang Si.
Thinking about all this, Chris's gaze towards Jiang Sidi became somewhat complicated.
So much so that Chris didn't hear a single word of what Jiang Si said afterward.
Jiang Si was unaware of her ulterior motives.
Using the topic of safety helmets as a starting point, she led the visiting group into the construction site.
Perhaps because they had made ample preparations in advance, they were able to handle the questions and inquiries from the crowd, whether they were questioning or curious.
Jiang Si always manages to give the most concise and satisfactory answer at the first moment.
This includes some little-known details in the design, as well as the changes made later.
From earthquake resistance and wind resistance to integration with the surrounding architectural style, she can talk about any topic with ease.
I had expected this visit to be filled with intense tension.
But after a few hours, the atmosphere was quite harmonious.
Even those who had previously questioned Jiang Si at the state-run store were now blushing with embarrassment.
However, Jiang Si remained remarkably calm when faced with praise from the crowd.
Before we knew it, it was almost noon, the hottest time of the day.
The morning's visit came to a temporary end, and the group, led by staff, went to Friendship Restaurant for lunch.
Jiang Si could finally relax for a while.
In these international exchange settings, very few people actually eat.
Most people take this opportunity to chat with each other and expand their network.
It seemed that Jiang Si was the only one in the entire room who was truly enjoying the food quietly.
