The birth of auspicious clouds

August 2005, the Beijing Organizing Committee for the Olympic Games began the Beijing Olympic Games (Beijing Olympic Games news, the Beijing Olympic Games said it) torch design research and planning work. Combined with the concept of organizing the Beijing Olympic Games, the torch design concept, design requirements and creation methods were determined through the analysis of the torch design experience of previous Olympic Games.

Based on the characteristics of the industrial design of the torch, in order to achieve a perfect combination of art and technology in the design program, approved by the Beijing Organizing Committee of the Olympic Games, it was determined that the design program of the torch is dominated by artistic modeling, and the combustion technology and industrial design at the same time call for the combination of the creation of the public call for entries and the directional commissioning of the creation of the combination of the creative approach.

On December 6, 2005, the Beijing Organizing Committee for the Olympic Games (BOCOG) held a press conference and issued an invitation for an open call for the torch design.

On December 8, 2005, the torch design team of Lenovo Creative Business Center officially started its work.

On February 28, 2006, Lenovo Creative Business Center submitted the proposal and entered the preliminary evaluation stage.

As of February 28, 2006, the Beijing Organizing Committee for the Olympic Games*** received 847 entries from design organizations and designers at home and abroad, of which 388 were valid entries.

On March 16, 2006, the "Xiangyun" design was selected as one of the top nine among the 388 entries.

On June 1, 2006, "Xiangyun" entered the top four.

June to August 2006, according to the principle of choosing the best artistic and technical design, the Beijing Organizing Committee of the Olympic Games (BOCOG) Executive Committee decided that the torch shape "Xiangyun" designed by the Innovation Design Center of Lenovo (Beijing) Co., Ltd. would be the artistic design of the torch for the 2008 Olympic Games, and that the internal combustion system of the torch designed and researched by Aerospace Science and Industry Corporation (ASIC) would be the technical design of the torch for the 2008 Olympic Games. The technical program of the torch was determined to be completed by Aerospace Science and Industry Group with the assistance of Lenovo (Beijing) Co., Ltd. to produce the torch samples combining the shape of the torch and the combustion system, forming the complete design of the torch for the Beijing 2008 Olympic Games.

In January 2007, the "Xiang Yun" program was approved by the IOC.

Artistic and technical characteristics of the Xiangyun

Artistic characteristics

The creative inspiration for the Beijing Olympic torch came from the "Xiangyun" pattern, which is "origin***sheng, harmony***integration". The cultural concept of auspicious clouds has a time span of thousands of years in China and is a representative symbol of Chinese culture. The design of the torch is inspired by the traditional Chinese paper scroll. Paper is one of the four great inventions of China, which was introduced to the West through the Silk Road. Human civilization spread with the advent of paper. The use of red lacquer on the torch, which originated from the Han Dynasty, makes it distinctly different from previous Olympic torch designs. The contrasting colors of red and silver create an eye-catching visual effect, which is conducive to various forms of media communication. The ratio of the top and bottom of the torch is evenly divided, and the auspicious cloud pattern and three-dimensional relief process design make the whole torch elegant and magnificent, with heavy connotations.

Technical features

The Beijing Olympic torch has reached a new technological height in terms of combustion stability and adaptability to the external environment, and it can maintain combustion in strong winds of 65 kilometers per hour and 50 millimeters per hour of heavy rain. The design is made of thin, high-quality aluminum alloy and hollow plastic parts, which is very lightweight. The lower half of the torch is coated with high-touch plastic paint, which is comfortable to the touch and not easy to slip off. The Beijing Olympic torch is a product of China's independent design and development, with full intellectual property rights.

The fuel used in the Beijing Olympic torch is propane, which is an inexpensive and commonly used fuel. Its main components are carbon and hydrogen, and after burning, there is only carbon dioxide and water, no other substances, which will not cause pollution to the environment.

In terms of craftsmanship, in order to be suitable for all sizes and ages, the torch needs to be as light as possible, so the outer shell is designed with thin, high-quality aluminum alloy and hollow plastic parts. The lower half of the torch is coated with high-touch plastic paint, which makes it feel comfortable and not easy to slip off. The Beijing Olympic torch is a product of China's own design and development, with full intellectual property rights.

The Beijing Olympic torch can keep burning in bad weather such as gusts, gales, strong winds (≥ 65 kilometers per hour), rain (maximum rainfall of 50 millimeters per hour), snow and hail, etc., and it can be clearly identified in all kinds of lighting conditions, which can fully satisfy all kinds of filming and TV camera requirements.

Lightweight appearance of the Olympic torch, has a galloping core, torch burning technology is also the torch on the sky into the ground to ensure that the Ny Olympic Games for the first time in history underwater torch relay - the sacred flame by the divers brought to the underwater, the designer explained that the torch is equipped with a specially designed flame chamber, to take a chemical method so that the torch, whether in the air or underwater are able to The flame was produced both in the air and underwater.

The sacred flame topped Mount Everest, the most important premise is not extinguished, as a symbol of the Olympic spirit of the sacred flame, never extinguished naturally become the most critical requirements, regardless of the strong winds, rainstorms, or snow, hail, the torch can be burned in any weather conditions. According to the IOC requirements, once the torch is extinguished, it should be lit with a safety lamp, which holds the kindling collected from Greece, but if the lamp goes out, it will have to be re-collected in Greece.

Already manned spacecraft into space in China, the sacred fire Everest from a technical point of view is not a difficult thing to analyze,, the Beijing Olympic torch at the beginning of the design, the torch put forward harsh technical indicators, whether gusts of wind, gusts of wind, and even up to 85 kilometers per hour to 100 kilometers per hour strong winds to 50 millimeters per hour rain, or a minimum of minus 6 degrees to a maximum of 45 degrees of temperature conditions, are To ensure the normal combustion of the torch, by the Chinese independent research and development of new technologies will ensure that the Olympic torch combustion stability and adaptability to the external environment has reached a new height, and this technology is regarded as the Olympic Games Organizing Committee Torch Relay Center's core secrets, not leaked. Designed and developed by the Aerospace Science and Industry Group torch internal combustion system for the Beijing 2008 Olympic Games torch technology program, and by the Aerospace Science and Industry Group is responsible for the completion of the torch shape and combustion system combined with the torch sample production work.

The process of design and development of Xiangyun

The research and planning of Beijing Olympic Games torch design started in August 2005, which was based on the concept of organizing the Beijing Olympic Games. Combined with the concept of organizing the Beijing Olympic Games, through the analysis of the torch design experience of previous Olympic Games, the torch design concept, design requirements and creation methods were determined. According to the characteristics of the torch industrial design, in order to make the design scheme achieve the perfect combination of art and technology, approved by the Beijing Olympic Organizing Committee Office, it was determined that the torch design scheme is led by artistic modeling, combustion technology and industrial design at the same time call for the public solicitation and directional commissioned to create a combination of the creation mode.

On December 6, 2005, the Beijing Organizing Committee for the Olympic Games (BOCOG) held a press conference and issued an invitation for an open call for torch design.

As of February 28, 2006, the Beijing Olympic Organizing Committee ****received 847 entries submitted by design organizations and designers at home and abroad, of which 388 were valid entries.

After the preliminary evaluation of the Beijing Olympic Games torch design competition, the evaluation committee of the preliminary evaluation and re-evaluation of the works, in accordance with the provisions of the evaluation procedure, three works were selected for the consideration of the Executive Committee of the Beijing Organizing Committee for the Olympic Games, and from June to August 2006, in accordance with the principle of selecting the best artistic and technical design solutions, the Executive Committee of the Beijing Organizing Committee for the Olympic Games determined that the torch shape "Auspicious Clouds", which was designed by the Innovative Design Center of Lenovo (Beijing) Co. Ltd.'s Innovative Design Center as the artistic design of the torch for the Beijing 2008 Olympic Games, and the internal combustion system of the torch designed and developed by Aisino Corporation as the technical design of the torch for the Beijing 2008 Olympic Games. It was also determined that Aisino Corporation, with the assistance of Lenovo (Beijing) Ltd., would complete the production of torch samples combining the shape of the torch and the combustion system, thus forming the complete design of the torch for the 2008 Olympic Games.

The complete design of the torch for the Beijing 2008 Olympic Games was approved by the International Olympic Committee (IOC) in January 2007.

In order that the Olympic torch, which will be carried across five continents, can convey the thousand-year Chinese civilization to the world, the design team chose the lacquer red, which is characteristic of the cultural symbols of China and its distinctive countries, as the theme color of the torch for the Beijing 2008 Olympic Games.

Because of the abundance of lacquer trees in China, the use of lacquer and the culture of lacquer ware have a history of thousands of years in China. The design team wanted to convey the warmth and harmony of the culture by skillfully applying the red color of lacquer to the "Xiangyun" inscription, the torch handle and other details. Therefore, how to adjust the authentic Chinese lacquer red color has become a key link in the design of the Beijing 2008 Olympic torch "Xiangyun".

After the success of the initial selection, Lenovo designers Zhou Lan and Zhang Jun, Shi Xiaoyan several people to form a design adjustment sub-team, according to the Beijing Organizing Committee of the Olympic Games feedback, to do the "Xiangyun" Olympic torch overall proportion analysis, overall shape adjustment and modeling, optimization of the red color, as well as the improvement of the use of sex.

In order to make the Beijing 2008 Olympic torch "Xiangyun" the upper part of the cloud pattern of the lacquer red can be the most perfect expression of Chinese civilization characteristics, Zhou Lan painstakingly. During that period of time, she not only carefully studied the color effects of various lacquer ware of different periods in the collection of Lenovo Innovation and Design Center, but also frequently traveled around the lacquer ware antique market in Beijing, and went to the library to read a large number of pictures of ancient lacquer ware, from which she searched for the best feeling for the red color of traditional Chinese lacquer ware. With this feeling, Zhou Lan began to modulate the color palette. After each color palette is made, she has to compare the visual effect of the color palette in different scenes under different lights. In order to figure out the nuances of the effects of different color palettes, Zhou Lan took the color palettes and compared them two by two, pondering over and over again. After three rounds of *** counting eighteen color plates, Zhou Lan finally produced the full Chinese flavor of the lacquer red effect. Zhou Lan also suggested that the torch grip part of the spray lacquer red rubber paint, which not only increases the touch of the torch hand when used, but also make the final auspicious clouds torch up and down are full of Oriental culture delicate and pleasant feeling.

The design adjustment sub-team in the torch up and down the ratio of the two parts of the 1:1 or the golden section of the better question also took a lot of effort. Qiu Jiayu, director of design strategy at Lenovo's Innovation and Design Center, participated in the design adjustment sub-team's discussions several times, using paper rolls to simulate the effects of different ratios, and repeatedly soliciting everyone's opinions. Adjusted to the golden ratio, the torch seems to be a bit more elegant; but the ratio of the upper and lower equal parts is more in line with the Chinese aesthetics that emphasizes the balance of yin and yang and the neutral atmosphere. In the end, the team used aluminum to make the golden ratio and the upper and lower ratios of 1:1 respectively, and we felt that the upper and lower ratios were more in line with the distinctive Chinese cultural characteristics embodied by the Beijing 2008 Olympic Games Torch Auspicious Clouds as a whole. !!!
