Homemade hot air balloon
1. First, we cut out 6 to 8 leaf-shaped pieces of paper from soft paper.
2. Fold them in half and glue their edges together to make a balloon.
3. Use tape to stick the four connecting wires to the bottom of the balloon. Use plasticine to secure the other end of the string to the table.
4. Try to adjust the speed of the hair dryer as slowly as possible. Aim the blower outlet upwards at the bottom opening and turn on the switch. The balloon will slowly grow larger, tighten the string, and lift off the table.
Generally speaking, invention is the process and result of applying the laws of nature to solve unique problems in the technical field and proposing innovative solutions and measures. Products are invented to meet people's daily needs. The results of inventions either provide unprecedented models of artificial natural objects, or provide new processes and methods for processing and production. Innovations and transformations in machinery, equipment, instrumentation and various consumer products, as well as related manufacturing processes, production processes and detection and control methods, are all inventions.
In the field of intellectual property, invention refers to one of the patent types of inventions protected by the Patent Law. It refers to new technical solutions proposed for products, methods or their improvements. Inventions in the field of patents have their prescribed protection objects or objects of protection.
Definition
In 1888, Darwin once defined science: "Science is the arrangement of facts, the discovery of patterns and the drawing of conclusions." Darwin's definition points out the connotation of science, that is, facts and laws. Science should discover facts unknown to people and use them as a basis to seek truth from facts, rather than pure fantasy that is divorced from reality. As for laws, they refer to the inherent essential connections between objective things. Therefore, science is a system of knowledge about the nature and movement laws of various things in the objective world that is based on practice, tested by practice and rigorously logically demonstrated.
Invention is the process and result of applying the laws of nature to solve unique problems in the technical field and proposing innovative solutions and measures. Products are invented to meet people's daily needs. Inventions can be divided into useful inventions and useless inventions. The results of inventions either provide unprecedented models of artificial natural objects, or provide new processes and methods for processing and production. Innovations and transformations in machinery, equipment, instrumentation and various consumer products, as well as related manufacturing processes, production processes and detection and control methods, are all inventions.
In the field of intellectual property, invention refers to one of the patent types of inventions protected by the Patent Law. It refers to new technical solutions proposed for products, methods or their improvements. Inventions in the field of patents have their prescribed protection objects or objects of protection.
Features
Inventions are different from scientific discoveries. Inventions mainly create things that did not exist in the past, while discoveries mainly reveal the existence and properties of unknown things.
Inventions are novel technological achievements and are not simply imitations of existing artifacts or repetition of plans and measures proposed by predecessors. A technical achievement cannot be called an invention if it can be found in an existing technical system that is identical in principle, structure and function.
Inventions must not only provide something unprecedented, but also provide something more advanced than previous technologies, that is, superior to existing technologies in terms of principle, structure, and especially functional benefits. Inventions always involve both inheritance and creation, and most of them are advanced in general.
The invention must be an innovation with application value, a clear purpose, and novel and advanced practicality. The invention plan must not only reflect the attributes, structures and laws of external things, but also reflect its own needs. Before the inventor creates a new product or new process, he has already pre-constructed the designed object according to the functional requirements in his concept, and during the invention process he constantly improves his plan according to the optimized functional goals.
Inventions are different from actual technology or on-site technology in actual production and engineering. Inventions must have application prospects and possible applied technical solutions and measures. Whether an invention can be applied to production processes or engineering activities also depends on whether it can be incorporated into existing technical systems or cause innovation in existing technical systems, and Capital, equipment, manpower, materials, management and market conditions. With an invention, there may not necessarily be a corresponding product or process, and it may not be able to solve practical problems in production and engineering.
Only when inventions are transformed into product development, process testing, and technological innovation, trial production, mass production, and promotion and application can they become real technologies.
Most scientific and technological inventions come from Europe and the United States, and the "materialization" of these inventions into new products or trial products also mostly comes from Europeans and Americans. However, the "final stage" work of turning a new product or trial product into a commodity worthy of mass production and launching it to the market is mostly done by the Japanese.
A survey organization made an international comparison of the number of new inventions, new products, and new commercializations around the world in the 20th century. The results are: First, the number of new inventions from the United States reached 29 In terms of items, the number of new inventions from Europe reached 11, while the number of new inventions from Japan was zero; secondly, the number of new products from the United States reached 30, compared with 6 from Europe, while the number of new products from Japan was only There are two items; thirdly, there are only 6 new products from the United States, which has the most inventions, and only two from Europe, while there are as many as 24 new products from Japan, which has zero inventions.
This shows that although Europeans and Americans are good at inventions, and to a certain extent, they are also good at "materializing" inventions into refreshing products; however, they often fail to "carry out the invention to the end" and truly realize Schumpeter's dream. The entire content of "innovation" as defined by the special definition, that is, the development of new products, new markets, new production methods; new sources of raw material supply, etc.
