What is the Educational Research Subcommittee of a New Era?

In November, 2013, the ”Educational Research Subcommittee o
New Era” （Japanese TRIZ Society, NPO） launched.

Chair： Shinsuke Kurosawa
In this study group, the research andguidance construction to utilize TRIZ
such as application methods and casestudies aiming “Way of Teaching TRIZ”
and “Utilizing TRIZ to Increase theEffectiveness of General Education” areset out, and activities are carried on
intending to spread and develop TRIZ.

Outline
One of the study themes is to design workbooks andexplanatory casebooks based on "Utilizing TRIZ to Increase
the Effectiveness of General Education" for students andgeneral adults.
Part of this study will be introduced.
【Contents】
1．Pick up an open task as the object for case designing.
2．Consider how to apply the "Substance-Field Analysis"and Standard Solutions, which are characteristic
methods of TRIZ, to the problem definition andsolution searching of the open task.
3．Apply "Substance-Field Analysis" and Standard
Solutions to the open task.

1．Pic up an open task as the object forcase designing
An open task is "Problem of no learning of theanswer as knowledge and searching for theanswer voluntarily."
TRIZ Master Anatoly Guin who advances thedevelopment and spread of law on education
based on idea of TRIZ. "Education in a New Era"
laboratory that he manages is advocating it.

Background and reason to take up open task
In the compulsory education and the higher education,
The only solution of someone finding solution with set
problem already. The problem where such a solution
exists is often taken up.
It is an education to teach answering so to speak. It is
not an education that voluntarily looks for the answer.
When from beginning to end of the education to teachanswering, the possibility that it becomes impossible to
do a creative idea rises.
In daily life and the business accomplishment, oneself
finds the problem according to the situation in which themany are put. It looks for the solution by making gooduse of creativity. The best action will be taken.
Then, as a research theme of the case-making, It was
assumed that "Open task collection" written by Anatoly
Guin was treated.

2．Consider how to apply the “Substance-Field Analysis"and Standard Solutions, which are characteristic methods of
TRIZ, to the problem definition and solution searching of theopen task"Place goods-analysis" is a feature technique of TRIZ.
The structure of 【Substance-Field】 which has the adverse effectcaused in the technological system and“problem of not functioning
enough” is analyzed. It tries to derive the settlement plan according to
the principle of the method of standard solutions.
The Substance-Field model is a model to analyze 【SubstanceField 】 structure. The triangular model by two materials (Substance)and places (Field) is composed.
The technological systems such as the material, tools, and parts andthe parts are called "Material". And, persons, living things and theenvironment, etc. are included.
Power and the energy that exists for the material to interact with one
another and to function are called “Field".

If the problem by “Place material-analysis” can beset, do not conceive the idea, and at random. A
systematic idea of free association can be expected
regarding to Compulsion association that uses indicatorthat finds solution of standard solutionとIdea conceived
by compulsion association
Standard solution ⇒ compulsion association ⇒freedom association
The solution is found multipronged, and the bestsolution will be set.
Everything need not be applied though it is said astandard solution of 76. Here, it thinks about
application that selects a generality and high standard
solution.

"Open task collection" written by Mr. Anatol Hin istreated.
It applies to some open tasks.
Place resource analysis and material-analysis, It
introduces the solution case with an open task
by it and the selected standard solution.

Open task case 1
Anatol Hin, Alexandre カフトリョーフ, 「Cannot explanation but explanation
The world pocket edition１」「 How did Beethoven who did not hear sound listen to music?」
Major composer in Germany, Ludwig van Beethoven comes to havepoor hearing due to sickness. It is known well to have lost hearing
completely in later years. However, he finds the method of overcoming
the predicament. It comes to be able to listen to piano music. The
favor made the composition of a new tune possible. For instance, when
he composes Symphony the most famous ninth, Beethoven did nothear of the sound at all.
How was Beethoven that was not able to hear the sound able to hear a
piano sound?

۞Beethoven who did not hear the sound, How did he listen to music?

2.The piano trembles.
3.The vibration of the piano is transmitted to the baton.
4.The vibration of the baton (The baton was bitten) is
transmitted to teeth.
5.The vibration is transmitted from teeth to the skull.
6.The vibration is transmitted from the skull to the snail.
7.Beethoven can listen.

Open task case 2
Anatol Hin、 Irina アンドレジェーフスカヤ、「Problem of 150 ofour surroundings」
The cherry of Uncle Vanya ripened. The cherry in thegarden of the house of Uncle Vanya has ripened savory.
However, there is a problem. It is necessary to defend
the cherry from starling's insect damage. When not only
the cherry but also an American cherry and the grape
ripen, the starling, the sparrow, and other birds fly and it
inadvertently puts it away by the turn.
Well, how can I defend the fruit of the case corner frombird's insect damage?

۞How can I defend the fruit of the case corner from bird's insect damage?
①Resource analysis(a)Bird's sightIt says roughly, and bird's sight is ..the same level as thehuman.. a little excellent.
- The seen color ･･･ For the human, three primary colors
and birds are four primary colors.
(A lot of birds see ultraviolet rays. )- Eyesight ･･･ It is very steady with the human.
- View ･･･ A lot of birds are wider than the human.
The range that can be the binocular vision instead is narrow.
- The bird is "Nighe-blindness" ? ･･･ Becoming accustomed
to darkness is late though it sees as much as the human.

②The goods-field model's construction
Place:Lift (volitation) and sightMaterial 1: Fruit（b）Aural of bird
Aural of the bird is more a little than human inferior.

～～～

Material 2: Bird

Harmful: It eats the flesh.
The third material
Standard solution：1-2-1(c)Taste and sense of smell
The number of cells (taste bud) that feel the taste is tens ofpieces in chicken and pigeon, and it is far fewer than about
10,000 humans.
However, I can feel the taste as it chooses and it eats fruits with ahigh sugar concentration.
In general, bird's sense of smell is not sharp for a similar human.
The clue to which the crow finds meat in the garbage bag has theexperiment example of confirming it is not a smell but it is a sight.

③Solution by standard solution- Correspondence to coming flying･So as not to put it in the orchard, the net is put.
- Correspondence to sight･The fruit is covered with the bag etc. and obscured.
･It throws up a smoke screen out and it obscures it.

Anatol Hin, Irina アンドレジェーフスカヤ、「Mole measures」
from 「Problem of 150 of our surroundings」
Will you have seen the mole tomb in green in the one
side of the field? It is the one that the soil that dug up
the road and the air hole as shown by underground Sumi
the mole was pushed out to surface of the earth. Even if
the mole builds the nest, it is not harmful at all if it isneither a farmland it is nor a kitchen garden. However,when the mole settles in the kitchen garden and the rootof farm products is damaged, the harvest is lost. Then,some measures are necessary. It has the acute hearing
though eyesight is lost because there is a mole always
under the soil.
Please think about measures to prevent the mole frombuilding the nest in the kitchen garden.

۞How can I defend farm products of the case corner from the mole?
