# Multiple Input Parameters for TRIZ Matrix Application

Classical TRIZ [1] (a Russian acronym; in English, "theory of inventive problem solving") was created by Genrich Altshuller between 1940 and 1960 [2]. In this method for creating inventions, the inventive principles matrix is the core, while advantage (plus) and disadvantage (minus) factors let you navigate the matrix. This method has seen continuing development; for example, the TRIZ matrix was updated and improved by D. L. Mann [3, 4].
A traditional way of using the TRIZ matrix (e.g. using a spreadsheet) is to choose a single input (one advantage factor against one single disadvantage factor). This Demonstration shows a new way by choosing multiple input parameters (advantage and disadvantage factors) to illustrate a statistical distribution for inventive principles. You may use it as a tool for looking for an inventive solution from the TRIZ matrix and 40 inventive principles. Mouse over each bar to show tooltips of the inventive principles.

### DETAILS

The source data is based on Mann's TRIZ matrix [3, 4]. This Demonstration uses the Mathematica function Tuples to generate all combinations between multiple advantage and disadvantage factors.
Snapshot 1: TRIZ matrix result with one advantage factor (1) against one disadvantage factor (1), as a case study for a precision measurement device
Snapshot 2: TRIZ matrix result with two advantage factors (2) against three disadvantage factors (3, including one random factor), as a case study for an advanced motor
Snapshot 3: TRIZ matrix result with three advantage factors (3) against three disadvantage factors (3), as a case study for a wafer stage system or projection lithography in the microelectronic industry
Snapshot 4: TRIZ matrix result with all advantage factors against all disadvantage factors, which exactly yields a frequency ranking of 40 inventive principles
