What is the all-Japan manufacturing scene great war?
■What is the scene great war?
It is a rally (bringing together the scene that small
and medium manufacturers in the whole country
are bet the boast of its company and made, andthe fight by the one to one). Manufacturingseriously designs a small scene, and everything ispoured and the technology that its company canhave with a professional machine is made. A
professional technique is fatty soaked of the ringon each other.

■What rule?
•Having kept turning longer than other party'sscene wins.
?It is defeated besides the ring when going out.
?Game end at two successive victories?The victor can get loser's scene.
(It is a content total removing of booty till then. )第１０回 日本ＴＲＩＺシンポジウム 2014.9.12

The first stage: Grasp of system: Specification confirmation (latest)
Specification of scene･The diameter of the scene is φ20mm or lessin the static condition against the rotation axis.
･The size is confirmed with the ring gauge of φ20.001.
･Turn only by the finger of one of hands.
Victory or defeat･It goes out or it is defeated besides the ring when previously stopping.
･When the tread stops though the parts other than the treadwith the ring move, it is defeated.
･If the game cannot begin from point by which the referee multiplied
the cheer of "Correspond" within 30 seconds, it is assumed one defeat.

Prohibited matter･The scene that keeps turning in the tread in two places ormore is prohibited.
･The scene into which the rotation axis changes is prohibited.
･The scene into which externals size changes
by the component replacement is prohibited.
･It is prohibited to touch the scene at time other than the gameafter it accepts.
･The use of a supplementary tool that assists andpromotes the rotation of the scene from the outside is prohibited.

Extraction of problem
As for a heavy solid of revolution, ⇔ center of gravity that moment of inertia
grows rises. The idea that solves this contradiction?【 contradiction problem 】
2. Torqueing is applied ⇔ fat one thin goes up the switch and the rotational
speed goes up. The idea that solves this contradiction?【 contradictionproblem 】
3. The switch is low ⇔ that turns length easily short and center of gravity is low.
The idea that solves this contradiction?【 contradiction problem 】
4. Center of gravity rises in the angle of bank though the make a careless pitchby the axis blur when largeness turns it on is few. 【 contradiction problem 】
5. The frictional drag grows by causing friction with the ring, and the scene heavy
as for the Scene point. Is a method frictional drag a little even if it is heavy?
【 contradiction problem 】
6. Let's devise the method of improving the rotational speed of the scene.
Besides, does the resource that can be used :?
7. The method of absorbing only rotation energy of other party scene?
8. The method of destroying stability of other party scene?
9. The method of flipping other party scene outside the room momentarily?
10. Method of no contact with other party and the method of not receiving theother party's influence?

What is the Taguchi method?
■Dr. Genichi Taguchi (1924 - 2012)■Taguchi method＝Quality engineering＝Robustness design（"Robust" means it, that is, "It is stout" or "Strength". ）■Technological technique to make product with good quality cheaply early･There are a lot of design parameters thatshould be examined when the scene isdesigned.
･Other party's scene cannot be specified, andthe state of the ring and pitcher's capability
vary, too.
・In such a situation, the technique to develop
a strong scene by "low cost for a short term"is the center technique of the Taguchi method.

Factor that engineer cannot control system：
It is in the delicate state by the noise. However, the internal design parameterthat the engineer can control is set.
And, the influence of the noise can be held down by optimizing it.

First of all, the noise-proof (robustness) is secured.
Next, it matches it to an ideal I/O relation.

The noise-proof of the function of the system is evaluated.
Signal-Noise ratio (ratio of signal/noise) is used as astandard.
To evaluate the noise-proof, noises such as the civil war
and turbulence (error margin factor) are included in theexperiment.
A lot of design parameters are taken up at a time.
It allocates to the orthogonalization table, it experiments,
and it evaluates it.

After all, was a strong scene able to be done?
If it is a scene that turns to the noise (opponent and state of thering) strongly, and long, it should be able to win other scenes.
It defeats it only to No.03. ！
