systematic innovation - I-TRIZ history, principle of ideality, abstract desc
Why we create abstract descriptions
viewpoints, chunking, relationships, formulation
What is TRIZ?
ØSystematic, structured way of thinking, analyzing, and innovating ØA repeatable methodology ØExtensive knowledgebase
What are the levels of invention?
5 levels. Apparent solution, minor improvement, major improvement, new paradigm, discovery.
TRIZ is "Classical TRIZ" :
40 principles
viewpoints
Analyzing the system from several different viewpoints allows us to deeply understand different components, characteristics, and relationships.
level 1 of invention
Apparent solution: -Routine design problems solved by well-known methods. No invention needed.
formulation
Creating abstract descriptions, the useful/harmful function names, and identifying relationships allows us to put the system/problem into a form facilitating innovative idea generation.
Level 5 of invention
Discovery: -A rare scientific discovery or pioneering invention of an essentially new system.
relationships
Identifying atomic relationships between components in the system is necessary to create the formulator diagram.
In I-TRIZ we create the following abstract descriptions
Input/output cause/effect past/future supersystem/subsystem states useful functions harmful functions contradictions problem formulator diagram
level 3 of invention
Major improvement: -Fundamental improvements to an existing system using methods known outside the industry.
level 2 of invention
Minor improvement: -Minor improvements to an existing system using methods known within the industry.
Level 4 of invention
New paradigm -A new generation of a system that entails a new operating principle for performing the system's primary functions. Solutions are found more often in science than technology.
What are I-TRIZ operators?
Operators trigger you to think of possible solutions to a problem
what is innovation?
The incremental improvement of an existing object or system by the elimination or mitigation of some undesirable qualities or the enhancement of desirable qualities.
chunking
The process of analysis and forces us to break the system into correctly-sized pieces ("chunks") that will fit easily into the Problem Formulator Diagram later.
What does TRIZ stand for?
Theory of the solution of Inventive Problems
Abstract description:
a depiction of a system internationally focusing on some details while omitting other details
I-TRIZ is "Ideation TRIZ" :
continuation of the work after relocation to USA and creation of ideation international
anything decreasing ideality is a
contradiction
in diagrams barred arrow mean:
counteracts
anything increasing ideality is called
innovation
how long have TRIZ and I-TRIZ been in development?
over 60 years
in diagrams straight arrow mean:
produces
