Technological inventions are divided into original technological inventions, improved technological inventions and combined technological inventions.
It is the essential feature of human beings to constantly understand and transform nature, and to constantly discover and invent something. Human beings created labor means and techniques by using natural conditions, and realized the nature of the external world and their own strength in the process of inventing utensils.
Invention is the starting point of technology and production activities. With the invention and application of making stone tools and making fire artificially, the history of human material production and social life began. Technological change and progress, the improvement of productivity and people's living standards, and the development of social history are all inseparable from development and creation.
The progress of ancient society depended on the invention of grinding stone tools, smelting copper and iron, making pottery and drying bricks, raising silkworms and weaving silk. The industrial revolution in the 18th century originated from the invention of new textile machines and steam engines. Electronic computers and a series of modern inventions have fundamentally changed people's working methods, living conditions and social outlook. The history of human civilization is first and foremost a history of invention and creation.
inventors in history are often unclear about the social significance of their creative activities. When they improve the existing utensils or crafts, they mostly proceed from their personal needs, and they don't and can't fully realize the great value and application consequences of their inventions. Moreover, they usually engage in inventions in an amateur way.
In modern times, especially in modern times, people have increasingly clearly recognized the importance of invention, solicited inventions by offering rewards, encouraged and protected inventions by using the patent system, and made inventions a specialized profession. Inventors have their own research and development institutions and organizations to exchange achievements, the research on the regularity of invention and creation has been paid attention to, and the education of invention and creation and the training of invention methods have been popularized. Modern technological inventions have been greatly improved in consciousness, quality and quantity.
Technological inventions should make use of knowledge of nature and scientific principles, and rely on technological innovation in production and engineering to play a role. Compared with invention, scientific research is more instructive and practical for material production. However, science must be invented before it can become technology, and technology must be invented before it can become new productive forces. Technological ideas and technical schemes are the intermediary from knowledge to practice, and they are the key links in the process of transforming science into productive forces and engineering applications.
