500mlの水を入れた複数の水風船を筒に入れる。
ペットボトルの太陽光で膨張した空気が、ホースの先の100均の逆向きにした注射器のピストンにつけた針を押し出し、水風船を割って給水する。
上の水風船は、仕切り板によって邪魔され落ちて来ない。太陽が沈み、ペットボトル内の空気が冷えて圧縮することで、針が引っ込むと同時に、仕切り版が引っ込むことで、上の水風船は下の位置に落ちて来る。

説明
太陽光で空気を膨張させ水を供給、夜、空気が縮小しタンクから水を補給する。太陽光で空気を膨張させ水を供給、夜、空気が縮小しタンクから水を補給する。

水の比重よりわずかに軽い小さいゴムボールと大きなプラのボールを紐で結ぶ。ペットボトル内に滴下水を入れると、プラボールが浮き出すが、小さいゴムボールは水圧で栓をする。ある位置までゴムボールが浮上すると紐が張られ、ゴムボールを引張る。ゴムボールは浮き上がり、同時に給水される。給水が終わると、ゴムボールは再び栓になる。

Target：Let's study the usage of USIT practicing it.
Result：An immature person to USIT, while studying, the idea that
was able to be made for the prototype was able to beshown.
Impression：It follows the procedure. Correctly, It can reach theanswer to be requested at last by piling up the result ofreview.
The future：The USIT use practice is piled up, with the knowhow
master, the technique improvement is researched.

[6]Reflection and point 1(1)It is the most important, and arranges the center problem.

→Does not the center problem contain two purposes or more?
This center problem：To the soil every day、It is a constant amount as for water. 、uniformlysupplies it.
↓Two purposes were contained.
Water is supplied in a constant amount.

and Water is uniformly supplied.

↓It becomes difficult to do the solution systematization.
It becomes difficult to put out the second solution.
↓
Water is supplied to the soil in a constant amount every day.
Water is uniformly supplied to the soil every day.
You should individually execute it separately.

13

[6]Reflection and point 2(2)Sentences and rough sketches are indispensable for the solution.

→Only no sentences、Is the rough sketch shown?
→Only no rough sketch、Is sentences shown?
Purpose in sentences and rough sketches①Is it the same idea or a different idea?
②Where is a different idea?
③The image is shared in the rough sketch.
④Sentences become indices when arranging and retrieving it.
This failure example
・The rough sketch of idea M03 that is the high score is not found.
→The content of the idea was not able to be recalled easily.
14

[6]Reflection and point 3(3)Clarification → disregard is → evaluation conditionand changes into the limiting condition.
①The limiting condition is clarified first.
This example：Cost is within 1000 yen.
Production is within 2-3 hours.

②The idea is being examined. The limiting condition is disregarded.
To a cheap idea because of the idea with high cost
To the idea at short time because of the idea with long production time

③When finally evaluating it, the limiting condition is added as an evaluation
condition.
Is the idea feasible within 1000 yen? →Cost
Can the idea be produced within 2-3 hours?→Time15

[7]It develops with the business.
“Be accustomed “ is more important than "Learn it".
(1)It is necessary to use it on business by force when learning it. 。
The grasp and the problem of my understanding level become clear.
(2)When my executing it, the center problem definition and making theSLP diagram are more difficult than the conception stage.

The technique of the center problem definition、Mr. Nagai'sannouncement
Cause search development（DeSC）- The source of a problem is covered -.
Please listen by all means.
