Systematic Innovation: Week 1 Material

Innovation is the solution to what problem?

Contradictions

What are the 5 levels of Invention?

1. Apparent Solution - routine design prob. resolved by well-known methods. No inventions needed 2. Minor Improvement-minor improvements to existing system using methods known within industry 3. Major Improvement- Fundamental improvements to an existing system using methods known outside the industry 4.New Paradigm- new generation of a system that entails a new operating principle for performing the systems primary functions. 5.Discovery- A rare scientific discovery or pioneering invention of an essentially new system

In I-TRIZ we create the following abstract descriptions (9)-

1. Input/output 2.Cause/effect 3.Past/Future 4.Supersystem/subsystem 5.States 6.Useful functions 7.Harmful functions 8.Contradictions 9.Problem Formulator diagram

4 reasons we create abstract descriptions:

1.Viewpoints- Analyzing the system from several diff. viewpoints. allows us to deeply understand diff. components, characteristics, and relationships 2.Chunking- the process of analysis forces us to break the system into chunks that will easily fit into the problem formulator diagram later 3.Relationships- identify atomic relationships between components in the system is necessary to create the formulator diagram 4.Formulation- creating abstract descriptions, the useful/harmful func. names, and identify relationships allows us to put the system/problem into a form that facilitates innovative idea generation.

What time period was classical TRIZ practiced?

1946-1992

What year was the company I-TRIZ founded?

1992

What is an abstract description?

A depiction of a system intentionally focusing on some details while omitting other details

We call the undesirable characteristics

Harmful functions

What does I-TRIZ stand for?

Ideation International

The goal of innovation is to:

Increase the desirable characteristics of a system and minimize the undesirable characteristics of a system

In the 1980s, scientists at what university began to look at how TRIZ was formulated?

Kishinev

How do you pronounce TRIZ?

Like trees

Who pioneered the TRIZ method?

Russian scholar/engineer Geinrich Altshuller

What is the definition of 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

What do operators do?

They trigger you to think of possible solutions to a problem

We call the desirable characteristics:

Useful functions

Who was responsible for the formation of I-TRIZ?

Zion Bar-El

Anything that decreases ideality is called:

a contradiction

In diagrams we use a barred arrow to mean

counteracts

Ideality is increased when

either the useful functions are increased or the harmful functions are decreased

Anything that increases ideality is called:

innovation

Contradictions either:

produce harm or counteract good

In diagrams we use a straight arrow to mean

produces

Most new things happen/improve in:

small increments

What does TRIZ stand for?

the Theory of the Solution of inventive Problems
