In recent years, rapid technological development has brought about economic prosperity and quality improvement of human life. However, it has also come with new problems, such as the impact on the environment and ecology. With the development of the global economy, the usage of energy has increased rapidly which resulted in serious global warming. Therefore, energy and environmental protection are the issues that governments of all countries attach to nowadays. In view of this, the 2019 Green Idea Invention and Design Exhibition is held. Green Idea means green technology and hopes to provide innovative inventions and designs that will solve energy and environmental protection issues in the future. At the same time, in order to enhance the culture of industry-university cooperation and innovation research and encourage outstanding talents to actively invest in innovative research and development. We hope to make this invention and design exhibition as a platform to promote the intellectual patent creation of outstanding inventors, promote international exchanges, and improve the marketing of patented products. The market value has further promoted the exchanges and cooperation between the industry, academia and research institutes.
