“Five rings of ice crystals” stunned the opening ceremony of the Beijing Winter Olympics

At the opening ceremony of the 2022 Beijing Winter Olympics, the crystal clear “five rings of ice” carved from the Ice Cube stunned millions of viewers. This area of 134 square meters, weighing about 3 tons of ice crystal five rings, behind the design and presentation, there are also Apelxs scientific and technological contributions.

The “ice crystal five rings” is 19 meters long, 8.75 meters high, and only 35 centimeters thick. Through the Wiya system of the National Stadium, it will rise to a height of more than 10 meters in 43 seconds, hang in the air, and finally slowly sink under the stage, during which the lifting accuracy can be controlled at the millimeter level.

After Apexls undertook the Olympic “snow and ice rings”, it carried out a careful design, the interior of the rings is composed of 360° LED ring screen without dead corners, which can realize the display of any picture, leaving maximum creative space for the opening ceremony director team, and the outermost diffusion plate makes a “beauty” for the display screen to ensure that the visual effect is clear and soft.

In addition to the light transmittance, the overall weight of the five rings also needs to be controlled within 3 tons, which also brings no small challenge to the design team. Finally, the researchers followed the structure of the arrow body of the space rocket, so that the five rings were light in weight but also strong, and could withstand strong winds of level 6.
