ATTENTION!

Algorithm is a tool FOR ORGANIZATION of thinking - NOT a REPLACEMENT of it!

Don't hurry. Carefully think over every STEP and write them down.

STEP 1

1.1

Technical system for     ...............(specify the Primary Function - PF)

               by means of  ...............(specify the Principle of Operation - PO)

               consists of    ................(enumerate the all parts of the system)

In the process of realization of the PF: .........(specify the PF),

a Harmful Effect 1 (HE1):                    .........(specify HE1) occurs.

In order to eliminate HE1:     .........(specify HE1),

Means Of Removing (MOR): .........(specify possible MOR) can be used.

But when using these MORs, new Harmful Effects 2 (HE2) occur.

...............(Specify HE2 for every MOR).

1.2

Write the scheme of the problem without professional terms:

1.3

Examine variants of the Technical Contradictions (TC) in their extreme states and write them down.

                        ____

TC1:  MOR ð HE1** ð HE2

IF MOR:           .........(Specify MOR) enter

THEN HE1:      .........(Specify HE1) removed

BUT new HE2: .........(Specify HE2) appears

          ____     ____

TC2:  MOR ð HE2 ð HE1

IF MOR:      .........(Specify MOR) don't enter

THEN HE2: .........(Specify HE2) doesn't appear

BUT HE1:   .........( Specify HE1) remained

Step 2. Formulation of the invention problem

_____     ____     ____

MOR ð HE2 + HE1

It is necessary to find such an X-element, which

while preserving the capability of ABSENTEE MOR: .........(specify MOR)

to not create HE2: .........(specify HE2),

would also remove .........(specify HE1).

Step 3. Determine the Operation Zone (Z_OP) -

- the space, where the conflict takes place

The composition of the Z_OP must consist of:

- An object, which will be subjected to a harmful influence (HE1), and

- An object, which exerts the harmful influence.

Step 4. Determine Operation Time (T_OP).

Operation Time - T_OP, which consists of:

- The time of conflict                                                 Т1

- The time prior to the conflict                                              Т2

- The time of fulfillment of the Primary Function      Т3

In a general case:

Т = T1 + T2 + T3

Three variants are possible, depending on the relationship between the time when the conflict takes place, and the time when the Primary Function performs.

4.1 Variant "Either Т1 or Т3 ":

Production process (Т2 = Т3), which has already begun, is interrupted by the conflict.

The system "waits" for the conflict to end (Т1) in order to resume the production process.

In this case:

Т = T1 + T3(T2)

4.2 Variant "Both Т1 and Т3"

The conflict takes place simultaneously with the beginning of the production process,

being its integral part.

Here:

Т = T1(T3)+ T2

4.3 Variant "Т1 part of Т3"

The conflict takes place only with definite parameters of the PF. As a rule, the system's goal is to reduce Т1 to zero, and to prevent its occurrence.

It this case:

Т = T3 = T1 + T2

Step 5. The Physical Contradiction on the macro-level - Macro-PhC

In Z_OP .........(Specify Z_OP) during ...(specify the time of a fulfillment of the PF Т3)

should be .........(specify the physical macro-state, e.g., "be long", "be hot")

in order to perform the Primary Function PF, and

should be .........(specify the opposite physical macro-state, e.g., "be short", "be cold")

in order to prevent the Harmful Effect HE1 at the time of the conflict

      .........(specify the conflict time Т1).

Step 6. The Physical Contradiction on the micro-level - micro-PhC

Between .........(specify contact surfaces) there must be particles of a substance, which

would:

- ensure .........(specify physical state of the best for a fulfillment of PF) and

- ensure .........(specify opposite physical state, in which ВE1 doesn't appear).

Step 7. Ideal Final Result - IFR

Technical system should ITSELF provide a presence of particles between .........(specify contacting surfaces), which would ensure .........(specify opposite physical states).

Step 8.

Formulate the demands on the characteristics of the particles which would ensure the conditions under which the HE1 would occur:

The particles must be.........

Step 9.

Analyze the composition of the system and figure out whether or not the system has the elements that are the required characteristics.

Step 10.

If the problem is solved move on to the part 7 of ARIZ-85B,

If the problem isn't solved, continue the analysis under part 4 of ARIZ-85B.
