Recently, many friends have sent messages and emails to us. Also, journalists and media all over the world have contacted us, so we need a great deal of time to reply them. As a result, some messages and emails may be overlooked or not replied timely. Your understanding will be appreciated.  

GOOD NEWS: Share our link with facebook or twitter to win a free air umbrella(air umbrella-a or -b).To let me know,please send me the links you share or the screenshot to my email adress:airumbrella102@sina.com,quantity limited to 5 before Oct7,2014 . 

Five of the lucky people won a free air umbrella,each of them could get one air umbrella(-a or -b) before  December 31st 2015.Those lucky people are:

Joel Lim  

Vandamme Etienne

Beshoy Girgis  

Vincent Leung

Air is everywhere on the earth. The flowing air can change the moving path of the object. The faster the air moves, the greater the energy is. The jet airflow can isolate some objects. So when we make use of the airflow, we can protect ourselves from the rain drops. Then the airflow forms an umbrella without a visible cover.

Based on this idea, we designed various types of air umbrella with postgraduates from Nanjing University of Aeronautics and Astronautics from July in 2012 to August in 2013.We also tested the air umbrellas on rainy days. 

Luckily, one of our samples achieved the goal of protecting one or even more persons from the rain in the test in November 2012. But the product still needed more improvement. As the sample was designed to take a large amount of airflow, the top was big, which didn’t achieve the portable characteristic.

To design a better looking product, we cooperated with a few PhD graduates from  Beijing University of Aeronautics andAstronautics to improve the design. After a year’s hard work, we finally improved the appearance of the umbrella which may influence the effect. But at least, we could really use it outdoor on rainy days.

In July 2014, we finished the new sample and colored the product to make it better-looking. And this sample is what we show as air umbrella-b in out pictures and videos.

Currently, we only put the air umbrella-b into practice. According to different demands of various users, we designed two more types of umbrellas based on air umbrella-b (basic style), that is, air umbrella-a (for female) and air umbrella-c( scalable). 

Based on the appearance of umbrella-b, we made design drawings of air umbrella-a and air umbrella-c for your reference.

Air umbrella-a is mini and could be put in bags,It is about 30  centimeters  in  length and 500 grams in weight,It is not scalable.The battery life is about 15 minutes.

Risks and challenges

In July 2014, we decided the basic plan for the first product. The plan achieved improvement in various aspects such as efficiency, appearance, flexibility and practicability.

From October 2014 to July 2015, we will improve our products from various aspects such as appearance,and auxiliary function (including power display function and mobile power supply function)based on the plan.

In September 2015, the first improved products will come out from factory.

Before December 2015, the products will be sent to our supporters.

It will still take nearly 10 months to improve the product.After the completion, we will send all the parts to the manufacturers for production. And the competed products will be sent to our supporters.If the products can not be produced successfully,we will return all the fund to the supporters.Besides,if we are not able to complete the products and send them to our supporters before December 31st 2015, we will return all the money to the supporters before January 31st 2016.
