The perfect end result of triz. See pages where the term result is mentioned. Perfect end result

Let us remind you that TRIZ is an obligatory part of classes at the Eidos Center. TRIZ is a theory of inventive problem solving. Formed by Heinrich Altshuller in the 70-80s of the last century. TRIZ is an applied science that requires constant practical use.

TRIZ helps to find STRONG solutions to the problem without trial and error, without a continuous enumeration of options. This solution is referred to as IFR (ideal end result).

The most effective solution to a problem is one that is achieved only at the expense of existing resources. In practice, the ideal end result is rarely fully achievable, but it serves as a guideline.

When looking for an IFR, you will definitely come across a CONTRADICTION.

Attempts to change in order to improve some parameters of the system lead to the deterioration of other parameters. For example, an increase in the strength of an aircraft wing can lead to an increase in its weight, and vice versa - lightening the wing leads to a decrease in its strength. There is a conflict in the system.

Example:

Geologists conducting research in Alaska complained about foxes that gnawed through the cables coming from the measuring instruments.

Contradiction: Foxes should not gnaw on wires, because. people are harmed by this, and foxes gnaw on wires (this is the reality).

An example of conflict resolution: Cayenne pepper is introduced into the sheath of the wires, the hottest variety known. And the attacks of foxes immediately stop.

We will talk more about the elimination of contradictions in the following articles.

Now try to solve a creative problem:

To wipe the nose of the customer or David?

In 1504, in Florence, Michelangelo Buanorotti was finishing work on a five-meter statue of David. Pierre Soderini, then mayor of the city, came to see how the work was going. He liked the statue. However, coming closer to her and looking up, where the master was working at that time, he said that David's nose, in his opinion, was too big. Michelangelo was at a loss: if you make corrections, the harmony of the sculpture will be disturbed, but if you don’t make it, you can quarrel with the customer and not get money. What should Michelangelo do?

But first, ask yourself these questions:

What parts does the system consist of, how do they interact?
- Which connections are harmful, interfering, which are neutral, and which are useful?
- Which parts and connections can be changed, and which cannot?
- What changes lead to the improvement of the system, and what - to the deterioration?

“The ideal end result can be likened to a rope, holding on to which a climber makes an ascent of a steep slope. The rope does not pull up, but it gives support and does not allow you to slide down. It is enough to release the rope from the hands - the fall is inevitable ”(Heinrich Altshuller)

RBI - Ideal End Result is one of basic concepts TRIZ. IFR is an image of solving a task (problem) with minimal (ideally zero) resource costs (labor, money, information, time, space, people, etc.), without complications and undesirable effects.

Real life example: A boy of eight years old was locked in a room by his sister. He faced a problem: how to get out? Use force, threats, raise a cry? But the door is too strong, there is no one at home, except for his sister, and no one will hear him ... He thought and made his sister SAMA open the door for him. The boy pulled up a chair on his side of the door and said, “Look, I THAT LOCKED YOU!” Within a few seconds, the sister herself opened the door, freeing herself "from captivity."

The boy can be called savvy by nature, but such resourcefulness, the ability to get out of the current situation in an unconventional way, can be learned with the help of TRIZ.

When formulating the IFR, it is desirable to use the word "Sam" (Sama, Samo, Sami). Commonly used ICT formulations are:

The CAMA system performs this function;

There is no system, but its functions are performed;

The function is not needed.

Do not think whether it is real or impossible to achieve it, doable or not doable, doable or not. Be creative!

How to put it in real PERFECT end result?

Do not guess in advance the degree of reality of the feasible. Ideality is a forward-upward direction. The bottom line is that any task must be solved in the direction of increasing ideality, striving for the ideal.

Do not think in advance how and in what ways the IFR will be achieved.

Use IFR keywords such as Sam, Samo, Sam, etc. The action should be performed by itself without additional mechanisms, devices, etc.

Imagine that you have a magic wand and what the result will be if you just wave it and say, for example: “Cribble crab boom!” (This technique will remove psychological inertia, you will eliminate the path to achieve the goal and focus on the end result).

Maximize the use of existing resources (material, energy, material, etc., primarily "free").

Use the ideal solution template: " everything remains unchanged, but the desired result is achieved" or " everything remains the same, but the unwanted effect is gone».

The acquisition of a useful quality or the elimination of a harmful one should not be accompanied by the deterioration of other qualities or the appearance of a harmful quality.

How can a preschooler be trained to seek, find, and formulate an Ideal End Result? Of course, with the help of game tasks and exercises, actively using fiction.

"Help Tanya get the ball"

Read to the child a poem by A.L. Barto "Our Tanya is crying loudly." Suggest thinking - how can you get the ball? Listen carefully to all the child's suggestions (trial and error), gently guiding him.

Take a wand. - Wonderful! But if the puddle is too big... You can't get the ball with a stick...

Go into the puddle and get the ball. - Great! But look, Tanya is in sandals, she will get her feet wet...

Let her go home then and put on her rubber boots. But the puddle is too deep, the water will get into the boots ...

Suggest your Ideal End Result: how can you make the ball CAM float to Tanya?

The range of options narrows, all actions are already performed with the ball: blow on it, create waves, throw pebbles, etc.

"The Robinson Crusoe Method"

It does not matter if the child is still too young to get acquainted with the work of D. Defoe. For fantasizing, you can use any available work.

We read "Aibolit" - wonderful!

Would you like to visit Africa? ... - You and I flew to Africa, but our plane broke down ... We need to build a house until dad saves us to protect ourselves from the sun, hurricane and wild animals; we need something to eat; we need to make clothes out of something, etc.

"The Magical Disappearance of an Object"

Draw the child's attention to any household items and suggest imagining what would happen if one morning everyone woke up, but ... there were no forks (chairs, cabinets, shoes, etc.) ... What should I do?

After checking for ideality (there is no object, but its function is being performed), tell the child that in ancient times these objects really did not exist, you can illustrate how people managed without them (this will lead the child to a systematic approach, which we will talk about later); if the child is able to fantasize, offer to come up with what this object might look like in the future).

"The robot is broken"

“In a certain kingdom, in a certain state, in one small town with very small inhabitants (you can think of the beginning of a fairy tale yourself), all items for the inhabitants were made by a robot. And one day it broke. Instead of brick for houses, furniture, clothes, asphalt for sidewalks, etc. he began to make only ... rulers (plates, albums, flower pots, etc.). How can residents use these rulers in their lives?

From personal experience: the use of substitute objects is an important stage in the development of preschool children's play activities. I don’t even know if such an abundance of “almost like real” toys in the modern toy industry is for the benefit of children. What our children just don’t have for playing, for example, “to the store” - and scales, and a cash register, and even plastic money-coins, and buns, sausages, eggs, milk cartons, etc. You don’t need to invent anything (brick pies, eggs - balls from rattles, money from finely torn album sheets or - aerobatics! - made by transferring a real coin through thin paper reverse side pencil) - everything is already ready-made.

But even now I observe a huge thirst for children to invent, fantasize. It is very important not to extinguish this spark. In our kindergarten, we regularly hold competitions for children and family creativity to stimulate the creative potential of pupils. How unusual to make a Christmas tree? (IFR - there is no Christmas tree, but something performs its function). The competition was attended by works made of paper, pasta, plastic bottles, thread, tinsel, natural and waste material. How to tell about your street? (The object speaks about itself) Layouts, drawings, collages, computer presentations were presented.

Tell us in the comments what you and your child did to achieve or get closer to the IFR when solving any creative, non-standard tasks.

How to find the strongest solution to a problem without solving it

There is an old, like the world, school trick: if the problem is not solved, they look into the answer of the problem book, and then the solution is "adjusted" to the correct answer.

What is bad and what is good about it? The bad thing is that the problem is solved "dishonestly", not entirely independently, and that the learning effect is reduced. And the good thing is that the problem is solved easily, quickly and correctly.

Is it possible to use this technique in life when there are tasks and there are no correct answers?

Experience has shown that it takes some time to get used to being ideal. Indeed, it’s wild: you just understood the problem, you don’t know yet, not only the answer, but also how to approach it, and then they immediately offer to formulate a solution and not simple, but the best for you personally.

Meanwhile, IFR reflects the main law of the development of technology (and not only technology) - the Law of Increasing the Degree of Ideality, in other words, the law of increasing the degree of satisfaction NEEDS person.

The IFR is practically unattainable, but theoretically one can approach the IFR as close as one likes. To do this, it is necessary to consistently remove all negative super-effects that arise as we approach the IFR.

Let's consider several practical problems with beautiful ideal solutions to show skeptics that ideal solutions are possible, then we will learn how to formulate IFR, and then get IFR.

Example 1 The Central Asian commander and emir of the Samarkand kingdom Timur (Tamerlane, 1336-1405), who defeated the Golden Horde and carried out predatory raids on India and Persia (Iran), was himself attacked by ferocious war elephants, followed by an innumerable army. What to do?

Tamerlane ordered to load hay on the camels, set it on fire and drive the camels towards the elephants. The elephants were frightened by the "sea of ​​fire" moving towards them, turned back and trampled on their own infantry. The victory over the enemy was provided by the resource of the enemy.

Formulate an IFR for this situation. Difficult? And not only because there is no experience, but also because in order to formulate IFR one needs complete looseness of thought - "I can do anything, I'm a magician!", as well as the ability to want and even ... courage.

How would you like these RBI formulations: "Elephants SAMI destroy their infantry and SAMI run away from the battlefield" or "The army of the enemy SAMO destroys itself." With this, you directed your thinking towards a strong decision.

Example 2 It is clear that the famous "airfield lights" must be especially reliable, because they are landing lights. That is, the entire system must be reliable: lamps, power sources, wires, contacts, switching equipment, cartridges, etc. etc. Difficult business.

We decided to put simple reflectors of the headlights of the aircraft. Reflectors are so simple that there is nothing to break, therefore they are reliable. But there is a fear, what if the aircraft headlights fail? Then they came up with "eternal" lamps or "ideal fire" - a sealed glass tube is covered from the inside with a special substance (zinc sulfide phosphor), which glows brightly under the influence of a radioactive substance mounted in the same tube. No wires, no connections, no power, lamp HERSELF glows brightly.

Rules for searching and formulating IFR

1. Having understood the task, set yourself up for what you can ALL! Even the impossible. You have a "sea" of resources, you are a magician! Don't be ashamed or afraid of your fantastic ideas!

2. Determine the main function of the system or the main process that needs to be improved. This is what should be done SAMO as they say, "nothing".

• with words SAMO, SAMA, SAMA,


• or by listing to whom and in what it should be good (the principle of I-I).

Word " MYSELF" implies that the system or part of the system performs the required action without cost, without an external resource. When we formulate the IFR with the word MYSELF, we specify the object in which we must first search for the resource.

Why formulate an IFR?

1. The IFR is unattainable, but it clearly shows the way to a strong solution, shows in "what direction to think." This greatly reduces the amount of trial and error.
2. According to the degree of approximation of the actually obtained solutions to the ideal one, one can choose the strongest solution. What is the IFR, such is the decision.
3. The "Formulation of IFR" technique can be used independently, for example, as a way of formulating GOALS almost any activity.
4. The formulation of IFR perfectly develops imagination, non-standard and independent thinking.
5. The formulation of the IFR reduces the search for solutions.
6. Formulation of IFR helps to predict. For example, let's predict the stages of the development of surgery: it was - "cut off and thrown away", then - to replace the organ with an artificial one, there is - to transplant, will be - to grow a new organ (regeneration).

Reception of problem solving - "Formulation of IFR" can be used in isolation, regardless of other methods of resolving contradictions. It's good to take it on board! The technique greatly simplifies the solution of creative tasks, especially if, after formulating the IQR, you managed to correctly answer the question: What prevents you from getting the IQR?

Having mastered the ability to formulate IFR, we can say that you have mastered the skill of fantastically quickly finding the best solution to any creative problem without solving it.

It is very useful to learn how to formulate and anti-RCI. Anti-RBI is the most undesirable, most terrible situation you can imagine. And then figure out how to get out of this situation, then everything else will seem like child's play to you. And then? Try to turn this harm into a good. And then figure out what needs to be done so that this never happens. It is very likely that after such an analysis, something will need to be done in reverse.

Ways to increase the degree of ideality (for adults).

1. Increasing versatility.

For example, wrist watches: determine the pulse, serve as an alarm clock, stopwatch, thermometer, microcomputer, radio, even a television screen. They show the weather, the schedule of all transport in the world ...

2. Destruction of the system as an independent unit and its transfer to the Supersystem, without destroying the function.

For example, headlights in old cars were strengthened next to the driver, he could control the headlight. Then they transferred the headlight to the fender, and now they drowned the headlight into the fender of the car. In new apartments, cabinets are built into the wall. The chassis used to be outside - now they make it retractable into the wing of the aircraft ...

Tasks for the concept of ideality (for adults)

Let's practice:

1. There is such an innocent at first glance question: What would you do if you had an unlimited bank account?
2. What PERFECT Work?
   Clue. By definition: there is no work, and all the functions of the work are performed.
3. Who it IDEAL human?
4. What PERFECT school?
5. What PERFECT helping a child? (Help without helping!).
6. What PERFECT child punishment?
7. Who is she PERFECT

When solving an inventive problem, a TRIZ specialist looks for a solution with high ideality, i.e. one that allows achieving the desired result at minimal cost. To search for such solutions, Altshuller developed a special tool - the IFR operator (ideal end result), which sets the inventor to obtain the desired effect by using available resources.

The IFR can be formulated in different ways. But the most common, classic formulation is as follows:

Ideal end result: X-element itself performs the required action (instead of some specialized TS), continuing to perform the function for which it was originally created.

At the same time, under the name " X-element" can hide either the problematic TS itself, or some of its subsystems.

Buoys are installed in the sea near the shore. They mark a line that ships cannot cross. The buoys glow in the dark - they are equipped with lamps and batteries. From time to time, batteries have to be changed and recharged - a special service works for this. In windy weather, when the sea is rough, battery replacement becomes a problem. The customer asks to solve this problem. Which way to solve it should be chosen?

The ideal recharging system is when there is no system at all, and its function is performed. Let's formulate the IFR: the buoy itself charges the battery, continuing to serve as the border of the zone allowed for navigation.

Is it possible to implement IFR in this particular case? To do this, you need to find a resource - free energy that can be converted into electrical energy. It is easy to guess that there is such a resource - it is the energy of waves. There are simple ready-made devices with the help of which a buoy swinging on the waves will be charged by itself. And a battery replacement system involving risky human labor will not be needed.

An inventive situation is given: it is necessary to improve the ideality of a room air purifier. What can be an X-element?

IKR-1: air itself separates dust from itself.

IKR-2: the filter element itself (without a fan and housing) purifies the air.

ICR-3: the wall of the apartment itself cleans the air from dust.

Exercise 8

1. Washing windows is a tedious job that you have to do all the time, otherwise the dust settling on the glass will very soon make the window opaque. In high-rise buildings, washing windows is also simply dangerous. Think about how to improve the ideality of this operation.

2. The duration of the moments when a person experiences thrills is very short. You need to take a lot of pictures to "catch" the right moment and get a photo of a person in this state. How, without taking a lot of pictures, how to photograph a human face at the right moment, for example, when riding extreme rides? Formulate an IFR.

3. In the spring, when the river floods, it may be necessary to quickly build a dam. It is long and expensive to import special building materials (concrete, stone, metal sheets) for this purpose. And improvised materials (sand, soil), unfortunately, are very quickly washed away by water flows. How to increase the speed and efficiency of the construction of such a temporary dam?

Resources

Resources for solving problems

To obtain a highly ideal solution, that is, to ensure the execution of a function at minimal cost, it is necessary to find the appropriate resources in the problematic system itself or in its environment.

In the previous chapter, we considered the problem of removing piles driven into the bottom of a river. What resources could be found to remove the piles?

It was possible to pull piles from the shore using people or horse teams. This requires workers, horses, long strong ropes, boats to fasten the ropes on piles, etc. It was possible to connect several rafts around the pile, swing it from these rafts and then pull it out of the ground with a lever. The rafts are needed large and strong, so that when the piles are pulled out, they do not go under water, do not fall apart. And we need people - strong and in sufficient numbers. Exotic solutions were also proposed: to lower people with saws in a bell to the bottom or to place a pile in a pipe and dissolve it with acid.

In fact, an ideal resource was used, the most powerful source of energy - the river itself. The strength of its flow exceeds the strength of all the workers combined, moreover, this resource is completely free and almost inexhaustible. The river can be used to remove piles in a variety of ways. For example, flood several barrels around the pile, tying bags of stones to them, and then, attaching the barrels with ropes to the pile, cut off the “anchors”. Pop-up barrels, if large enough, will pull the pile out. In this case, the lifting force of the water will do the work. You can also use the kinetic energy of the flow of water - to make a "water sail". To do this, you will have to lower the cloth into the water, tying it to the piles, and let the river flow that fills this “sail” turn the piles out of the bottom. Or, as was done, you can fasten logs to the piles and, waiting for the ice to drift, watch from the bank how the moving ice will tear out and carry away the piles.

So, the solution to any problem, as in the example above, largely depends on finding and competently using resources.

A resource is space, time, substance, energy, information that can be used to solve a problem.

Highly ideal solutions are obtained using the resources that are already in the system. If the required resource is not available, it can often be obtained by modifying existing ones. For example, if you need to use a liquid to solve a problem, and only solids are available, the liquid can be obtained by melting. Finding, "computing" and using resources is one of the important components of the skill of a solver.

Resource types

It is useful to know the classification of resources in order to search for them not randomly, but systematically. There are energy and material, spatial and temporal, information resources.

Energetic resources. In almost every vehicle there are sources of energy and strength - both explicit and hidden. Even in such a simple vehicle as a pile, one can detect the longitudinal and transverse elastic forces of the material that resist pressure, the weight of the pile, and the energy of burning wood. In the “river” supersystem, there is the kinetic energy of the movement of water, the weight of water, the Archimedes force ... The interaction of different systems can also generate certain forces: flow pressure on the pile, friction force and heating of the contacting bodies.

Material resources can be all substances that are in the system or its supersystems. In the problem of removing piles, a real resource can be considered water in the river, ropes, draft horses, stones and sand on the shore and bottom.

Spatial resources are the space that can be used to solve a problem. "Emptiness", features of the form of objects that can be used to change the original system or to increase the efficiency of its operation. An example of the use of spatial resources is the proposal to completely drive piles into the bottom. The resource here is the space under the bottom, which is usually not taken into account in the decision.

Temporary resources are periods of time that can be used to improve the functioning of the system, to perform additional operations. A classic example of this kind of resource is the combination of the execution time of two different operations, say processing an object while it is being transported.

Separately, it should be said about information resources. All of the resources listed above can be considered informational if they carry important information for a person. So, an information resource for an experienced sailor is the swirl of water over an object submerged in water.

In real situations, there is not always exactly what is needed to solve the problem. Changing, modifying the original resource in order to bring it to the desired form is an important part of the solver's work. These kinds of modified resources are called derivatives. For example, cellulose, which is part of piles, cannot be used as a resource, but after impregnation of cellulose with certain chemicals, a composition is formed that can burn under water. In the presence of such a derived resource, piles can simply be burned.

And what does a car cost society? The answer to this question is as difficult as it is important.

At the dawn of motoring, there was a frantic struggle to increase the speed of the car. Immediately there was a problem of stability on the road, especially when cornering. The car became lower, longer, wider. The bearing part became heavier - the frame, the base of the body. In order to move faster and accelerate, more and more powerful engine- and intensifies chassis: gearbox, cardan gear, driving wheels.

The requirements for the reliability of brakes are growing - and the mechanical drive is being replaced by hydraulic, and then pneumatic. A compressor appears, and with it a whole pneumatic system ... The suspension is improved - springs, shock absorbers, level stabilizers. To ensure the safety of passengers in a collision, the body is made of thicker metal.

Again, the weight and dimensions are growing ... And all this to transport one or two, maximum 7-8 people!

It only seems that the car is on four wheels. In fact, it is an octopus with hundreds of thousands of hands. In the US, for example, one in six workers work for him directly or indirectly. Consider for yourself: approximately 10 million cars are produced annually.

They use hundreds of types of ferrous and non-ferrous metals, non-metallic materials (plastics, leather, fabrics, etc.), radio engineering, varnishes, paints, glass, rubber, fuels, lubricants ...

The production of all this does not pass without a trace for environment, gives rise to a lot of environmental problems.

Design offices, laboratories, test benches and ranges. Automatic lines and robots for the manufacture of thousands of parts every second. Kilometer assembly lines. Computers and computers for CNC machines, for planning, collecting and analyzing information ... More? Please!

We need roads. In the United States, roads now occupy about 10% of the country's area. Their construction and maintenance require a huge fleet of special machines that can extract materials, pour them, fasten them, cover with asphalt and concrete, apply marking lines ...

A car, like any car, sometimes breaks down. You need equipment and tools for repairs. Thousands and thousands of auto repair shops. Gas stations, oil producing enterprises and refineries, a network of pipelines and giant oil tankers. Again, environmental issues.

The car must be stored somewhere. And huge areas of the territory of cities are allocated for garage complexes. It is necessary to maintain order on the roads, and a special national traffic police service is being created.

Accidents happen on the roads, people are killed or maimed. This means that we need medicines, first aid kits, ambulance stations, hospitals and sanatoriums. And funeral teams...

Not cheap, however, the car is very expensive!

Any system, be it a car or a fishing rod, is created and exists not for its own sake, but for the sake of performing some useful function for a person. So, the main useful function of a car is to move people and goods from place to place.

Strictly speaking, a person needs this function, and not at all the system that performs this function, giving rise to a mountain of all sorts of problems.

From this point of view, TRIZ has the concept of an ideal system:

An ideal system is a system that does not exist, but whose function is performed.

close to perfect vehicle By the way, Pushkin's Baba Yaga had it: her stupa moved “by itself”. But the stupa itself was still there, you had to get into it, you had to get out of it, so this vehicle is not one hundred percent perfect.

A completely ideal version of a car looks like this: there is no car at all, but you arrive at a given point at the right time.

And you don't need a rod. You need the function it performs. And what is its main function? Throw a worm, hook and pull out a fish that will swallow this worm.

Think about the question of the “ideal fish” for yourself. Just don’t think that such a fish should take off its own scales, gut and dive into the bowl with the fish soup. Indeed, in an ideal ear there should not be fish, but its smell, taste and nutritional value should be.

From all this follows one practically very important position:

All systems develop in the direction of increasing the degree of their ideality.

In TRIZ, other laws of system evolution (ZRS) have also been identified, but this law - the law of increasing the degree of ideality of systems - is perhaps the most important among them.

When solving specific inventive problems, this law makes it possible to abandon many empty samples and immediately formulate the ideal answer to the problem - the ideal final result (IFR). As in the case of the worm. The ideal worm itself falls into the water, holds itself there, and itself extracts the fish that has eaten it from the water.

Sometimes this is enough to solve the problem.

Of course, in most cases it is not possible to obtain IFR in its pure form. The meaning here is somewhat different. Setting the IFR allows you to immediately choose the right direction of work, narrow the search area and concentrate efforts on finding strong solutions to the problem.

Let us illustrate the operation of the law of increasing the degree of ideality by the example technical system.

The serial car "Niva" weighs 1150 kg and has a 53 kW engine (about 70 hp). To participate in international auto racing, the Niva was modernized: a boosted engine was installed, which developed power up to 200 hp. with., and the weight of the entire car was reduced to 700 kg.

The numbers of absolute (arithmetic) change usually say little: it was - it became. Relative indicators speak much more. Previously, each Horsepower engine carried 1150 kg: 70 liters. With. = 13.5 kg/l. With.

Now each “horse” carries only 700 kg: 200 hp. With. = 3.5 kg/l. With. Almost four times less!

Can city officials make a million out of nothing? Out of nowhere, unknown. And from zero - for sure, they can! The fact is that in Madrid, on one of the central squares, from where the mileage of roads in Spain is measured, a bronze zero is laid in the asphalt. Most of the tourists visiting the city are traditionally photographed at the Madrid zero. Naturally, for a fee that goes to the city treasury ...

Task 1. The fight against reckless drivers on the roads is an important task of the traffic safety service. Of course, in the presence of a traffic cop, all drivers strictly follow the rules, but on all roads and intersections you can’t put a traffic cop on. How to be?

This problem is solved in all countries. In Japan, for example, on one far from perfect day for local reckless drivers, the number of police officers on the roads has sharply increased. Seeing a policeman, the reckless driver had to quickly slow down and comply with all other traffic rules.

And only when they got closer, the drivers noticed with annoyance that most of the “cops” were dummies! But there were some real ones...

Replacing an object with its copy is one of the typical techniques used in TRIZ. But now we will pay attention to something else: there is no object (a living policeman), but its function (traffic control) is performed.

Here's another example.

Task 2. On the Crimean coast, it was necessary to fill up a new beach. It was supposed to be covered with pebbles - rounded pebbles, but only gravel was available - stones with sharp edges. What to do? Take out pebbles from other beaches? Invent a machine for processing gravel?

It was decided to use the gift power of the surf. Barges with gravel were unloaded directly into the sea, two hundred meters from the shore. The rest was done by the waves: they rolled over the sharp edges of the stones and carried them ashore.

As you can see, both examples illustrate the law of ideality well. When using this law to solve problems, it is important not to forget the word “self” (“self”, “self”). There is no trick or trick here. Remembering that the system itself, through the use of resources, achieves the required action, we immediately cut off a lot of weak and helpless solutions.

Indeed, the drivers themselves (without the presence of a living policeman) began to abide by the rules, the sea current itself (without the involvement of cars) ran around the edges of the stones, the tourists themselves (without insistence and requests) replenish the city treasury of Madrid ..
