Chapter 5 Air Umbrellas

I saw a sketch with full lines gradually taking shape on the whiteboard. Zhao Ping'an is quite confident in hand-painting.

This may be the most successful thing in his four years of college career, because he has been thinking about making a picture of the goddess who has been thinking about it for four years, but it is a pity that he has always felt that he is not good enough and never dared to really write. When I feel that the heat is about the same, the school is already on holiday.

This is a cylindrical object with a length of 50cm. It is divided into two sections. The diameter of the thicker lower section is 6.5cm, and the upper section is 4.5cm. It looks like two sleeves, and the top of the upper sleeve has a height of 2cm. It is a sheet-shaped cylinder with a diameter of 10cm, a closed top cover, and the bottom surface is connected to the sleeve. There are dense oval-shaped small holes evenly distributed around it, which has a sense of sight of an alternative shower head.

There are some arrows marking the trajectory line next to the object, and when the three interviewers have seen the same, Zhao Pingan outlines a transparent object with elegant strokes on the top of the unknown object whose overall shape looks like a pharaoh's scepter. Umbrella mask.

"This is?"

The three interviewers are not mediocre, and they were immediately attracted by this idea full of fantasy, but it is not enough to know the autumn from this pair of hand-painted with good skills. After all, this is not a complete design drawing. He looked at Zhao Ping'an suspiciously.

"Everyone, this is my idea, the design according to the client's request—the air umbrella!"

"What the hell? Air...umbrella?" Zhang Weiming frowned and said, "Isn't it a little whimsical?"

In his opinion, this is not design at all, but more like a fantasy. After all, product design must follow the premise that the product can be manufactured, and air as an umbrella?Simply unheard of!

On the other hand, Zhou Xinghua touched his forehead and put on a thoughtful look.

Jiang Yaqi, who was outspoken, kept urging: "Go ahead, keep talking."

Zhao Ping'an was very satisfied with her impatientness, and his aversion to her was greatly reduced. He said slowly: "The air umbrella, as the name suggests, omits the umbrella cloth on the traditional umbrella and replaces it with air."

"How? How to replace?"

In fact, it is not difficult to see from Jiang Yaqi's devotion at the moment that she is not a person with complicated thoughts, but more just paranoid, who is not right about things and people. At a young age, he became one of the five design directors of Yunchuang, a well-known domestic design company.

"The principle is very simple."

Zhao Pingan smiled at her and said, "Flowing air can change the trajectory of objects. The faster the air moves, the stronger its energy, and the jet of air can isolate some objects."

"You mean..." Jiang Yaqi's breathing became a little short, "use the air flow generated by the air flow to form an invisible transparent umbrella, so as to isolate the rain and keep people from getting wet?"

"Bingo! Correct answer."

Jiang Yaqi stared at Zhao Pingan with a confident smile on his face, dumbstruck, and was stunned for a moment. Isn't this just a wild idea?What a genius idea!
Why didn't she think of it?Until now, she no longer dared to underestimate this student who graduated from a third-rate university. You must know that Edison, the king of inventions, hadn't even finished elementary school. The simple truth of a hero.

Zhou Xinghua, who was sitting next to her, stared at the hand-drawn drawing on the mobile whiteboard without blinking, and said with a serious expression, "Xiao Zhang, explain your idea in detail."

As Yunchuang's most senior design director, Zhou Xinghua's vision can be described as extremely fierce. Unlike Zhang Weiming, from his understanding, this idea will be designed into a product with [-]% certainty.

He was just a little puzzled, is this really an idea that can be formed within 10 minutes?You must know that the high-achieving students of the first-class universities in the past basically started from the appearance. Few people dared to challenge the functional design in such a short period of time, let alone such a creative idea!
Even he himself, who has been informed of this commission for a week, has not come up with any good ideas.

For Zhou Xinghua, Zhao Pingan can't say that he hates him, but he can't say he likes him either, because his not-so-rich life experience tells him that the more this kind of person who always has a smile on his face and looks harmless to humans and animals, the more likely he is to like him. Good at scheming.

"Everyone, please look." Zhao Pingan pointed to the two-section cylindrical sleeve, "This is the umbrella handle. I made a segmented design here, so that it can be shrunk and it is more convenient to carry. Especially for women, the umbrella handle shrinks. The final expected length is 27cm, so there is no problem putting it in the bag.”

"And here." Zhao Ping'an pointed his finger at the bottom of the sleeve, where a slightly flared shape was formed.

He continued: "This is the air inlet, the air enters here first, and then several miniature centrifugal fans need to be installed inside the casing. We can learn from the design principle of the multi-plate deep well pump. The number of fans depends on the specific needs. and the available space, so that after the air passes through layers of fans, the flow speed will become faster and faster, and when it reaches the uppermost sheet-type top cover, it will reach the peak value, and then it will be sprayed out from the distribution hole in the outer ring of the top cover. So as to achieve the purpose of isolating rainwater.”

"Not bad!" Jiang Yaqi said with a somewhat excited expression: "This is definitely an imaginative design, and it may be shortlisted for the CF Design Award."

"One question." Zhou Xinghua frowned and asked, "Where does the driving force come from? Electric energy? Such a high-power driving method still has a narrow design space. The utilization rate of aging? Have you considered these? Ni-MH battery or Li-ion battery?”

Even Zhao Pingan had to admit that Jiang was still old and hot, and the oldest Zhou Xinghua had a more comprehensive view of the problem, and the driving force was the most difficult part of his overall conception.

"The aggregate lithium-ion battery is undoubtedly a good choice. It has superior cycle performance, high charging efficiency, and large output power. Considering the design space of the air umbrella, it can be equipped with a 7.4V, 4000mAh or 12V, 5000mAh aggregate lithium-ion battery. Then depending on the final energy consumption, the estimated usage time is 15-30 minutes.”

"Uh, that's right." Speaking of this, Zhao Ping'an seemed to suddenly think of something, and added: "The umbrella handle will also be equipped with an energy adjustment button, which is realized by connecting the coupling switch of the centrifugal fan, so that the energy of the air cover can be controlled. Size, this is an optimized solution for the convenience of multiple people, and it is also a variable of the working time of the air umbrella, which needs to be taken into consideration in the design.”

"Only 15-30 minutes?"

Zhang Weiming's expression is obviously a bit disdainful. If there is only such a short working time, then the air umbrella is completely useless, and as the size of the air cover becomes larger, the working time is estimated to be shorter, maybe only a few minutes, isn't it? It means that the user may be drenched in water at any time?
Sigh... After all, he is a child who has just left school, so the idea is too exaggerated.
