The architect from the USA Adam Kalkin created a unique lodging. The architect managed to locate a full-scale house inside another house. The “upper” building is created in industrial style and is an original “shell”, which outwardly reminds a cargo container with spread-apart doors and huge windows. One part of the house is the hall, while another one includes three living rooms in high-tech style. Somewhere in the middle there is an ordinary two-storey cottage. This building was erected in New Jersey, at the plot of land, the area of which is 1.2 hectares. The author named it “BunnyLane” (“Rabbit’s road”).
2. Task.
These three problems are built around the main character – fox. There is some more substantial similarity in them – in order to solve these problems, it is necessary to exactly formulate an ideal final result (IFR). Formulate IFR and solve the problems.
- Problem. Mad foxes. Author of the problem: V.Timokhov.
Out of wild animals the fox is more often the carrier of madness. In order to prevent the promulgation of this illness, which is dangerous for the humans, for long time foxes were ruthlessly shot out in Europe. Finally the vaccine against madness was invented, however it is impossible to make the foxes come to the places, where they are vaccinated. What’s to be done?
- Problem. Fox cubs and Film Shooting. Author of the problem: N. Rubina
The journalist V.Peskov, while shooting the film about the life of animals in Alaska astounded the American film –makers, who saw how five fox cubs rushed at the camera. Foxes are very easy to frighten and it seemed to be impossible to shoot such an episode – the fox cubs did not let the people come closer. How did they manage to shoot close-ups of the fox cubs?
- Problem. Where is the fox? Author of the problem: N. Rubina
What do you think, what animals are most numerous in tundra? The hunters in tundra are interested in arctic foxes, red foxes and weasels. Tundra means very large territories covered with snow. The hunters may look for their trophies for several days, also under the conditions of severe frost and strong wind. How can one quickly identify, where arctic foxes, red foxes and weasels moved?

1. Task.
Almost in every house one can find several remote control panels: for a TV set, for a photographic camera, for multi-cooker and for other electric equipment. And each model, for example, the model of a TV set, requires its remote control panel. Some companies tried to manufacture all-purpose remote control panels for different brands of TV sets, however, they appeared to be too complicated, expensive and could not take new TV set brands into account. One more problem of remote control panels consists in the fact that they are often lost and it is difficult to find them at once. Many users encounter a difficulty of dealing with a large number of buttons, which are often not used at all.
Suggest your own solutions, enabling to do away with these disadvantages as well as other disadvantages of remote control panels. What TRIZ tools did you use thereby?

1. Task.
The main feature of an inventive problem is the presence of a contradiction. Irrespective of the field of activity, to which the problem relates, it is possible to formulate the contradiction of requirements: in case one requirement is adhered to, another one is not adhered to.
Formulation of RC – requirements contradiction:
IF (describe the possible change), THEN (indicate the necessary positive requirement or action), HOWEVER (indicate non-desirable consequences).
For example, as applied to the problem of a remote control for electric devices, requirements contradiction could be formulated in the following way:
If one remote control is designed for several brands of TV sets (an all-purpose remote control), then (+) the user need not acquire several remote control panels, however, (-) such a remote control is difficult to use and cannot imply taking new brands of TV sets into account.
This system is characterized by one more requirements contradiction:
If the buttons for additional functions are located on the remote control (for example, a switch-off timer, subtitles mode, etc.), then (+) the user could quickly perform many additional actions upon the TV set, however, (-) remote control will be made more complicated and becomes rather unwieldy.
These are examples of formulation of requirements contradiction for an engineering system. Quote examples of requirements contradictions in non-engineering fields (in biology, literature, in painting, in history, etc.).
2. Task.
Write, what material and non-material systems you know. How do they differ one from another?
1. Task. Doctor Aibolit (Doolittle) needs a thermometer.
Mercury thermometer was invented very long ago. Inside a glass tube there is a plate with figures and lines and another thin tube is attached to it. The mercury goes up this tube, when heated.
As you see, the structure of the thermometer is simple. This is the advantage of it, but there is a disadvantage as well: it is difficult to distinguish, to which level the mercury raised in the thin tube. Besides, glass thermometer is rather brittle, it is easy to break it and the mercury, which is included with its structure, is a very dangerous substance. That is why thermometers appeared with another operation principle, which doesn’t have such disadvantages; however, they don’t yield such accuracy of measurement and are more expensive. Prepare a presentation dedicated to history of using temperature measuring devices since the 16th century up to our time. What thermometers, in your opinion, will be invented in the 21st century?
2. Task.
Prepare a list of the museums of your city, which are the most interesting for you. Which of them offer a possibility to trace the evolution of inventions of the man in the field of engineering, in clothes, in art, in literature, in transport and in other fields of human activity? Prepare a presentation dedicated to one of such museums, implying the illustrating of evolutionary processes. Give clarifications, which of TRIZ tools and Trends of Engineering systems Evolution (TESE) could be seen in these examples.
3. Task.
Which of the engineering inventions of G.S.Altshuller seems to be the most interesting and important to you? Describe it. Which of TRIZ tools are used for creating this invention? In what reference sources is it described? Is it used in our times? Offer an evolution of this invention taking into account modern potentiality and vital problems of modern technology.
Nomination “Inventive Activity”
1. Problem concerning the place for charging device.
The first version of Healbe fitness tracker implies the existence of a separate charging device. (see picture). In order to charge the device the bracelet should be taken off the hand and charging device should be placed upon it. The contacts of the charging device are located on the lower surface of the sensor, so that they should not be seen, when the device is in use on the hand. All this is not very convenient, since during the process of charging the contact with the hand of the user is lost and such data is not read as the heart rate, inflow of energy, etc. It would be desirable to charge the Healbe bracelet, for example, in the process of work on the computer through the USB port. However, in this case there will be no place on the bracelet itself, enabling to locate a micro USB connector. If it is situated on the lower surface, there will be no access to it, when it is put on the hand. One cannot arrange this connection on the upper surface because of aesthetic considerations. To locate the micro USB at the sides of the bracelet is also problematic because of the detachable belt, which embraces the entire lateral surface of the bracelet body. If we make a whole in this belt, it will be much less strong and will soon be torn. Besides, USB connection is waterproof, while Healbe is a waterproof device.
It happens rather often that they suggest using a non-detachable way of charging the device based on electromagnetic induction. However, such a device requires that it should be taken off the hand and besides, it occupies a lot of place inside the bracelet body and is unsuitable for solving the problem. The request is to suggest the idea of solving two problems.
1. What is the way to attain water-resistance in using micro USB connection for charging the device?
2. What is the way to locate micro USB connection in the body of the bracelet, so that the charging should be performed without taking the bracelet off the hand, without using the upper surface of the bracelet and without loosening the belt of the bracelet?
Your proposals should be substantiated. What TRIZ tools did you use?
2. Problem of transition to another zone time.
Healbe fitness tracker implies constant monitoring of parameters of the human health, which is reflected in the form of diagrams on a smartphone: heart rate, inflow and outflow of energy, evaluation of the stress level, etc. (see picture). Many users change their time zone during travels and flights and then a necessity appears to correct these diagrams in connection with the change in the zone time. If for example, the time is one hour ahead, emptiness appears on the diagram, the duration of which is one hour. If the time lags behind, the diagrams overlap. The biggest value of such a shift (forwards or backwards) could amount to 12 hours. It is necessary to take into account that the fitness tracker should constantly monitor the human health and offer a permanent diagram. It is utterly undesirable to loose information during travels and flights.
What is the way to reflect the diagrams of state of health of the human on a smartphone in case of time zone changing? Formulate your proposal and substantiate it. What TRIZ tools did you use thereby?
3. Designing a device for testing the pulse wave sensor.
In order to calculate the heart rate of the human it is necessary to automatically analyze the shape of the pulse wave. To achieve this, it is necessary to develop the algorithms of such an analysis, which enable to analyze fairly different shapes of pulse wave. A peculiarity of pulse waves is predetermined by the uniqueness of each human organism, besides, the pulse wave changes in connection with the variation of heart rate during the day and in the process of vital activity depending upon physical activity. The function of a pulse wave sensor within the Healbe bracelet is performed by the pressure sensor (the pulse wave exerts pressure upon the sensor, which is located on the wrist and the required signal is generated). To check the algorithms being developed one needs a test rig, which imitates the pulse wave on the human wrist. One could use an ordinary plastic bottle, which is filled with water. A bracelet is put on such a bottle and the strikes over the bottle imitate pulse waves. However, in this case it is very difficult to make the strikes over the bottle acquire similarity to pulse waves; it is still more difficult to make them calibrated. Such solution does not yield a necessary result. Suggest an operation principle and the design of such a test rig for a Healbe bracelet.
4. Problem of concurrent measuring of pulse wave and ECG in the Healbe device.
One of the main components of the monitoring of state of human health is the heart activity and the measurement of pulse wave parameters. One is based on the optical couple, in which the light diode lights the subcutaneous capillaries and the rhythm of pulse wave is determined according to the satiation of capillaries with light. Lighting requires fairly large energy expenses. The second approach is associated with the fact that in passing of the pulse wave small pressure is exerted upon the surface of the skin (it is most convenient to place the fitness trackers on the human wrist, where they usually carry wrist watches). The pressure sensors require much less expenses of energy, therefore, this particular method of recording the pulse wave was selected for this version of Healbe fitness tracker.
In the course of development of Healbe bracelet a necessity appeared to measure the signal of ECG concurrently with the pulse wave. For this purpose an additional electrode is located on the surface of Healbe bracelet, which the user touches with the finger of another hand. Induced electric signal enables to record the electric activity of the heart function.
However, it is associated with new problems. The thing is that the finger itself is the source of mechanical oscillations (tremor, strikes of pulse wave)? And when it touches the body of the bracelet it distorts that pulse wave, which comes from the other hand. Because of that it is impossible to read two signals simultaneously: an electric one (ECG0 and a mechanical one (shape of pulse wave). An electrode for ECG could be located laterally, however, when it is touched with a finger, the entire body starts to tremble and the pulse wave is distorted. Neither does the location of the electrode on the bracelet yield any result. First of all, mechanical oscillations are nevertheless transferred to the pressure sensor and distort the shape of the pulse wave. Besides, it is rather difficult to transfer the electric signal from the dismountable belt to the body. Mechanical oscillations will not be transferred, if the electrode is embodied in the form of a flexible tape or a flexible wire, however, it is very bad from the aesthetic standpoint and the structure could break in the course of operation.
Suggest a method of concurrent reading of ECG and the pulse wave signal. What TRIZ tools did you use thereby?

6. On enhancement of accuracy of recording the expenses of energy of the human organism by the Healbe device.
In the process of physical activity the human expends saved energy. This energy is measured in kilocalories. Its expense depends upon the age, sex, level of physical preparation of the human, however mainly it depends upon the level of physical activity of the human at the given moment of time.
Healbe fitness tracker is equipped with three main sensors:
- three-axial accelerometer, measuring acceleration according to three directions;
- impedance sensor (electric resistance of the human body at different frequencies);
- pulse wave sensor (pressure sensor).
Readings of accelerometer are usually used for control over expense of energy. Not all kinds of physical activity are equally reflected in the readings of accelerometer. For example, riding a bicycle is practically invisible in the diagrams of accelerometer data, since the hand is immovably located on the handle of the bicycle. It is not possible to install additional bracelets, for example, on the leg, since it is inconvenient and leads to additional expenditures.
What additional sensors in the bracelet itself could be installed in order to enhance the accuracy of calculation of energy expense? What is the way to enhance the accuracy of energy expense in the Healbe bracelet without installing additional sensors?
Substantiate your proposals. What TRIZ tools did you use? Could you name patent documents, describing inventions with a similar solution?

A bracelet is put on such a bottle and the strikes over the bottle imitate pulse waves. However, in this case it is very difficult to make the strikes over the bottle acquire similarity to pulse waves; it is still more difficult to make them calibrated. Such solution does not yield a necessary result. Suggest an operation principle and the design of such a test rig for a Healbe bracelet.
4. Problem of concurrent measuring of pulse wave and ECG in the Healbe device.
One of the main components of the monitoring of state of human health is the heart activity and the measurement of pulse wave parameters. One is based on the optical couple, in which the light diode lights the subcutaneous capillaries and the rhythm of pulse wave is determined according to the satiation of capillaries with light. Lighting requires fairly large energy expenses. The second approach is associated with the fact that in passing of the pulse wave small pressure is exerted upon the surface of the skin (it is most convenient to place the fitness trackers on the human wrist, where they usually carry wrist watches). The pressure sensors require much less expenses of energy, therefore, this particular method of recording the pulse wave was selected for this version of Healbe fitness tracker.
In the course of development of Healbe bracelet a necessity appeared to measure the signal of ECG concurrently with the pulse wave. For this purpose an additional electrode is located on the surface of Healbe bracelet, which the user touches with the finger of another hand. Induced electric signal enables to record the electric activity of the heart function.
However, it is associated with new problems. The thing is that the finger itself is the source of mechanical oscillations (tremor, strikes of pulse wave)? And when it touches the body of the bracelet it distorts that pulse wave, which comes from the other hand. Because of that it is impossible to read two signals simultaneously: an electric one (ECG and a mechanical one (shape of pulse wave). An electrode for ECG could be located laterally, however, when it is touched with a finger, the entire body starts to tremble and the pulse wave is distorted. Neither does the location of the electrode on the bracelet yield any result. First of all, mechanical oscillations are nevertheless transferred to the pressure sensor and distort the shape of the pulse wave. Besides, it is rather difficult to transfer the electric signal from the dismountable belt to the body. Mechanical oscillations will not be transferred, if the electrode is embodied in the form of a flexible tape or a flexible wire, however, it is very bad from the aesthetic standpoint and the structure could break in the course of operation.
Suggest a method of concurrent reading of ECG and the pulse wave signal. What TRIZ tools did you use thereby?

6. Task. On enhancement of accuracy of recording the expenses of energy of the human organism by the Healbe device.
In the process of physical activity the human expends saved energy. This energy is measured in kilocalories. Its expense depends upon the age, sex, level of physical preparation of the human, however mainly it depends upon the level of physical activity of the human at the given moment of time.
Healbe fitness tracker is equipped with three main sensors:
- three-axial accelerometer, measuring acceleration according to three directions;
- impedance sensor (electric resistance of the human body at different frequencies);
- pulse wave sensor (pressure sensor).
Readings of accelerometer are usually used for control over expense of energy. Not all kinds of physical activity are equally reflected in the readings of accelerometer. For example, riding a bicycle is practically invisible in the diagrams of accelerometer data, since the hand is immovably located on the handle of the bicycle. It is not possible to install additional bracelets, for example, on the leg, since it is inconvenient and leads to additional expenditures.
What additional sensors in the bracelet itself could be installed in order to enhance the accuracy of calculation of energy expense? What is the way to enhance the accuracy of energy expense in the Healbe bracelet without installing additional sensors?
Substantiate your proposals. What TRIZ tools did you use? Could you name patent documents, describing inventions with a similar solution?
