The distinction between innovation and invention is considered another of Schumpeter's major contributions. Schumpeter believed that as long as the invention has not been actually applied, then it is economically ineffective.

Whether it is a scientific invention or a technological invention, before the invention is transformed into a commodity, the invention is just a new idea, a new idea, and no economic value can be created until they are transformed into a new device, a new product, and a new process system. He also argues that "innovation as an entrepreneurial function is not necessarily an invention of any kind.

Therefore, it can be said that invention is one of the necessary conditions for innovation, but it is not a sufficient condition. For technological innovation that originates from scientific and technological inventions, invention is only one link in the innovation process. In other words, innovation is a type of human creative activity, and its essence is to create.

Creation has different customary names in different fields, for example, the custom of creation in the field of science is called "invention" or "discovery"; The habit of creation in sports competitions is called "breaking records"; The creative habit in the field of literature and art is called "creation"; The habit of creation in the field of technology is called "innovation"; Wait a minute.

Although innovation and creation are related, there is still an essential difference.

First of all, innovation is an economic concept that must be profitable. If a new product is produced according to a new idea, although it is very novel, if it cannot be applied and there is no profit, it can be said to be an invention and creation, but it is not an innovation in the strict sense.

Second, invention is an absolute concept, while innovation is a relative concept. For example, when applying for a patent for an invention, you must first consider whether you are the first to do it, and if someone else has already done it, you will not be able to apply for a patent again. It is absolute on the issue of "first" or "first".

Innovation is a relative concept, and it does not have to be like applying for a patent to find out whether it is the "first" or "first", whether it is the first person to do it. Innovation has a relative scope, do not need to consider whether in the department, the system has been done in the past, only should understand the degree of doing, what progress we have made after we have done it, and at the same time this progress can have benefits, this is innovation.

Third, there are both positive inventions and creations that promote social development and negative "inventions and creations" that hinder social development. And innovation must be a positive creation for social development. For example, the development of computers is positive creation, while computer fortune-telling and computer viruses are negative creations; The development of nuclear science and technology is a positive creation, while the development of nuclear science and technology is a negative creation; The development of biological and chemical sciences is a positive creation, while the biochemical ** and drug refining technology are negative creations. However, innovation is different, and no one would call pseudoscience or fake and shoddy technology innovation.

Fourth, the emphasis of creation is the first initiative, or it can be a new creation after a total rejection;

Invention itself is innovation, Luban on the basis of proficient technology, bold innovation, the invention of Luban lock and other devices, is innovation. But this is also not the category of English, no one is perfect, and mistakes are often made.

An invention is an idea, sketch, or model of a new or improved device, product, process, or system. Such inventions are often patentable, but do not lead to technological innovation. In an economic sense, innovation is only completed when the first commercial transaction of a new product, process system or device is realized, although the term is also used to describe the whole process.

Usopp was a well-known braggart as a child, and was made up of several children from the village. Usopp invented the shoe with a spring on the sole.

Make a [Simple Compass]:

Find a sewing needle, rub it on the magnet a few times to magnetize it, tie it in the middle with a thin thread for sewing clothes, hang it in a place where there is no wind, keep it horizontal, the magnetized sewing needle will change direction by the action of geomagnetism, and after it stabilizes, the magnetic needle indicates the direction of the north and south poles.

Due to the influence of wind and thread stress, this method is not very accurate, and the better method is:

The magnetic needle is fixed to a small piece of foam wrap material to float on the water, and the magnetic needle is changed by the action of geomagnetism, and after the magnetic needle stabilizes, the direction of the north and south poles is revealed.

1. Usually some old batteries will be found in the drawer, but I don't know if there is electricity, if you put it into the electrical appliances to check it is very troublesome and there is no way to know the amount of electricity left. So, you can make a small electroscope.

The method is as simple as this: use a small light bulb, a very small one (like the one on a pendant or toy lamp, which is sold in hardware stores). Then connect two thin enameled wires to the lamp separately.

The other end of the two wires is used to connect the positive and negative poles of the battery you want to inspect. According to the brightness of the small bulb, you can judge the battery level.

2. Take a broken umbrella, remove the cloth, take a wire, connect one end to the TV or radio, and the other end to the umbrella, which is a good signal receiver. If you want to be professional, just wrap a few more wires around the umbrella. It's the most cost-effective, quickest way, and just a little hilarious.

3. Put a match and a large needle together with a quilt, wrap them tightly with the aluminum foil of the cigarette, and then bend the aluminum foil at the end of the match head to seal and twist tightly. Then attach a directional tail near the tail and pull the needle out, and it becomes a very simple recoil rocket.

During the experiment, a small rocket was placed on a wire stand, a match was lit, and the part of the aluminum foil tube wrapped in the match head was heated. When the temperature rises to the ignition point of the match head, the matchbox in the foil is ignited, causing the surrounding air to expand dramatically, and the gas is ejected from the tail mouth at high speed. As a result of the recoil, the bazooka flew forward from the rack.

If you wrap two head-to-head matches in aluminum foil, leave them unclosed at both ends. Place it on top and heat it from the middle. When the match in the barrel is lit, the gas is ejected from both ends, and the foil cylinder remains on the rack, thus indicating the conservation of momentum in the system.

4. Rivete two identical protractors at the center of the circle and rotate flexibly, and break a gap of l centimeters long along the right end of the protractor above, when measuring the angle, let its opening coincide with the two sides of the angle to be measured, and the scale indicated by the notch is the degree of this angle; When drawing the corners, first align the notch with the specified scale, and then draw two rays along the opening. This protractor can also measure the angle of three-dimensional objects such as nuts. Because this protractor resembles a scissor when used, it is called a "scissor protractor".

Small transparent glue plays an indispensable role in many places in life. However, when using it, users often use various helpless methods such as biting with teeth and pricking with a pen to tear the tape because they do not have scissors at hand. This scotch tape has a small "V" notch at the edge, which can be easily cut off by simply changing direction when the tape is torn to the notch.

Just a simple small change can add "big" convenience to life.

Don't think it's too simple, it's called a gizmo.

None of us are scientists, how can we invent any electric lights or something?

Support ha.

I'm just like you ... Think about what difficulties there are in life, and then think about inventing.

I'm in my second year of junior high school, and I'm looking for it, oops, annoying.

Get two batteries to use as a flashlight when you connect a light bulb.

Remove the motor of the four-wheel drive, connect the battery, and cut a few wings on the head with cardboard to use d as a fan.

me too I'll ask my cousin and cousin...

Hand generator, 2 toy small motors with long gears, 2 batteries with transparent glue, 2 leather wires connected to the starting small motor, must have leather, otherwise it will be short-circuited accidentally! The other end of the wire is connected to the + and -of 2 batteries, and 2 skinned wires are connected to another small motor, and the other end of the wire is connected to a small bulb, glue well, loosen the 2 batteries, and pinch the two ends of the battery if you want to generate electricity, a small motor is rotating, and the other small motor is also rotating together, turn and turn, and the small bulb will be on!! That's it!

Solar-powered toy cars.
