In many real cases, TRIZ idea generation tools like 40,

cannot be applied directly to the initial problem situation

because of complexity and obscurity of it.

Not only idea generation thinking tools of

TRIZ but also analytic tools of modern TRIZlike Function Analysis, Root Cause Analysis,Feature Transfer, etc. are hardly used directly

from perception of the initial situation.Additionally, we need to decide which TRIZtoo s ou e a opte or pro em so v ng

after investigation of the initial problems ua on.

Function Analysis requires a certain time viewpoint among several timeo tions.

Part of FA-1 Part of FA-2

Root Cause Analysis needs a previous research on a series of eventsalon chan e of time and arametric condition.


6/18

Feature Transfer is done based on the preliminary understanding of theoverall operation diagnosis of the competing systems.

Energy Efficiency?

Safety?

Accommodation?

Occasion Axis is a novel analytic thinking tool

to guide problem solvers to proper idea generation tools oro guide problem solvers to proper idea generation tools or

analytic ones

according to investigation of the initial problem situation.

Occasion Axis is a thinking process in which we examine

what happens under occasions based on certain parametershat happens under occasions based on certain parameters

through the whole problem situation.

At each Occasion the problem situation is examined from

the viewpoint of interactions and parametershe viewpoint of interactions and parameters.

Interactions are evaluated according to the parameters of

each Occasion and then we get different diagnoses.g

Occasion Axis can be used with any other TRIZ tools

especially with System Scale as Multi Screen Thinkingspecially with System Scale as Multi Screen Thinking.

Occasion Axis might replace the classical Time Axis[1]

Results and Discussion

Occasion Axis has been applied to realpro ec s or pro em so v ng o g o acompanies like Samsung, Hyundai, POSCO,

- , . .Through Occasion Axis, the whole picture ofthe initial roblem situation could be ot

systematically and the result of it gaveproblem solvers the directions of theo ow ng pro em so v ng ac v es.

Occasion Axis can be integrated not only

problem solving tools.
