TRIZ. A LITTLE PRACTICE

Now you can add to the list of tricks you know.

10. Transition from the macro level to the micro level (from “pieces of iron”, levers, hinges, etc. - to the movement of molecules, atoms, ions).

11. Application of thermal expansion for microdisplacements.

12. Application of corona discharge (measuring surface curvature, monitoring the state of gas, obtaining charged particles).

13. Using the transition through the Curie point to automatically turn on and off electrical devices.

14. Use of soap bubbles and foam (filling space with a substance if there should not be a substance in this space).

15. Geometric techniques: use of the Möbius strip, hyperboloid, etc.

In addition, you learned that, having received a task, you must first formulate an IFR and strive to achieve it: a good solution is always close to the IFR.

Now let's try to practice using these tools.

Problem 37. LET'S THROW OUT THE SCREW!

When you look at something through a microscope, sometimes you need to slightly move the glass on which the object in question lies. You need to move it literally by the thickness of a hair - by hundredths and thousandths of a millimeter. To do this, they use screws: you rotate the screw, it moves the glass. But making such precision screws is expensive and difficult.

Engineers gathered and began to think: what to do?

“Technical contradiction,” said one engineer. - Precise screws are expensive, cutting quickly deteriorates... And with larger cuttings there will be no required accuracy.

And then an inventor appeared.

- Let's completely throw away the screw!

What should be used to accurately move a microscope slide?

You will probably solve problem 37 without even finishing reading the conditions. However, there is a subtlety here: if you read this chapter carefully, you will give three correct answers at once.

Problem 38. SOMETHING SIMPLE

Polymers age. This process is reminiscent of metal rusting, because the culprit of aging is oxygen, which destroys polymer molecules. To protect against oxygen, it is necessary to introduce finely ground iron into the “cauldron” when “cooking” the polymer. The iron atoms will intercept the oxygen and protect the polymer. But the finer we grind the iron, the more actively it will combine with atmospheric oxygen even before being added to the polymer. Once oxidized, iron will lose its protective properties.

“We’ll have to work in an inert gas environment,” said the chemist invited for consultation.

“It’s difficult and inconvenient,” the factory engineers objected. - We would like something simpler...

And then an inventor appeared.

- Please! - he said. - There is a very simple solution.

What do you think the inventor proposed?

You can easily find an idea for solving this problem. But try to think of an answer so that it is more specific.

Problem 39. POWDER ON THE CONVEYOR

A conveyor line operated at the mining plant - from one workshop to another. Finely ground ore, moving from conveyor to conveyor, eventually arrived at the furnaces. The workers servicing the line complained to the engineer: the ore is like powder; at the slightest breath it rises into the air.

- So what to do? - said the engineer. - We wet this powder, but it’s of little use: the water evaporates quickly. But you can’t get it too wet... Maybe cover it with something on top? But you will have more work: you will have to lay something down, then remove it...

And then an inventor appeared.

“There must be a covering,” he said, “so that there is no dust.” And there should be no coating, so that there is no unnecessary hassle. Therefore, it is necessary...

What do you think should be done?

Please note that the conveyor line must be maintained. The goal is to prevent dust from forming.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Bacteria will protect the foundation from subsidence 06.11.2016

British scientists are developing "biocement" - genetically modified bacteria that can prevent subsidence of the earth under the foundations of buildings.

When the ground beneath a building begins to sag, it can turn into a costly repair or a real disaster. But if scientists from the UK succeed, genetically modified bacteria will one day restore the soil. Inspired by another team's success with a concrete-repairing bacterium in an artificial biology competition, a British biodesigner and colleagues have developed "biocement". This material is based on specially modified soil bacteria that will multiply in response to changes in soil pressure, which will significantly strengthen the soil under the foundation.

To achieve this goal, the team grew E. coli in an artificial substrate, a hydrogel, encapsulated. They subjected the bacteria to overpressure, which is 10 times the pressure of the water on the seafloor. The scientists then identified 122 bacterial genes that tripled their activity after the change in pressure. The biologists then modified the bacterial genome so that the DNA regulatory region responsible for activating one of these genes was attached to another gene that causes light during reproduction. Thus, the higher the pressure exerted on the microbe, the stronger it glows.

When all observations are made, the researchers will replace the glow gene with a gene that will create the so-called "biocement", which in theory will serve as a self-healing foundation.
