1 Introduction to TRIZ Educational training Part 1

2 Agenda 1.Introduction 1.The Need for Innovation. 2.TRIZ as a key for structuring the process. 3.Guided Brainstorming Process 2.Challenge and Problem 1.Nature of Inventive Problems. 2.Psychological inertia and barriers 3.Levels of Solutions. 3.Define Objectives 1.Ideality, Ideal System 2.Ideal Vision, Objectives 4.Formulate Opportunities 1.Function Modeling 2.Three Opportunities for Improvement 5.Generate Ideas 1.Inventive principles and generating Ideas 2.Guided Brainstorming 6.Develop Concepts 1.Evaluate Ideas 2.Combine ideas into concepts 7.Solution

3 The Need for Innovation Lev & Gu Model Economic Performance = α(Physical Assets) + β(Financial Assets) + δ(Intangible Assets) Drivers of Stock Performance Shareholder return is most closely correlated with growth in earnings from intangible assets. Developing intangible assets requires competency in innovation. Physical Assets Financial Assets Intangible Assets Economic Performance “Innovation is the central issue in economic prosperity.” – Michael Porter

4 Innovation Dilemma Innovation process simple in concept…….. Recognize Problem or Need Develop Solution Implement 3000 raw ideas = 1 commercial success Stevens, G.A.; Burley, J. Research Technology Management Innovation = Invention + Exploitation Problem:

5 Basic Concepts of TRIZ TRIZ (pronounced as “trees”) Russian acronym for Theory of Inventive Problem Solving Originated in 1946 by Genrich Altshuller from the study of patents. Key Insights: People invent better with abstracted principles than with guesswork Studies of inventions can identify a comprehensive set of principles to use Genrich Saulovich Altshuller 10/15/26 to 9/24/98

6 Guided Brainstorming Process Transform a challenge into a well defined inventive problem Define opportunities and generate preliminary ideas Evaluate ideas and develop solution concept Define Objectives Formulate Opportunities Generate Ideas Develop Concepts Solution Challenge and Problem 3 Phases - 6 steps Our purpose is to preserve the power and simplify several elements of TRIZ

7 What is an Inventive Problem? No known means for solution High psychological inertia Different levels of solution Contains one or more contradictions A contradiction is a situation where an attempt to improve one feature of the system leads to the degradation of another feature.

9 Levels of Solutions Number of trials using Trial-and-Error Level % Inspection Level % Engineering Level 3 4.3% Innovation inside the paradigm Level % Innovation outside the paradigm Level % Discovery

10 Contradiction Company Car Your View? Company View? Cost Cutting Run Amok Or Six Sigma Gone Bad!

11 Define the Challenge and Problem The initial statement may not really define the problem Review the background of the problem Collect available data Redefine the problem Wrong problem = wrong solution Define what should be improved What is the gap between where you are now and where you want to be? What obstacles prevent easy movement to close the gap?

12 Guided Brainstorming Process Transform a challenge into a well defined inventive problem Define opportunities and generate preliminary ideas Evaluate ideas and develop solution concept Formulate Opportunities Generate Ideas Develop Concepts Solution Challenge and Problem Steps 2: Define Objectives Define Objectives

13 Basic Concepts of TRIZ: Ideality ∞ Sum of Useful Functions Sum of Harmful Functions Systems tend to evolve towards increasing ideality 50% 98%2%2%

14 GoodBetterNearly Ideal Primary Function of a Paper Clip = Hold Two Pieces of Paper Together Ideal System = Papers held together without the Paper Clip existing ∞ Sum of Useful Functions Sum of Harmful Functions Ideal System Ideal System - the function gets performed without the system existing

15 Chamber Destruction Problem Container Acid Specimen

16 Acid Specimen Chamber Destruction Problem 1.Exclude container from the system 2.Now, find another way to keep the acid in contact with the specimen Imagine an Ideal System - the function is performed without the existence the system.

17 Acid Specimen/Container Chamber Destruction Problem

18 Define Objectives What the final result will “look like?” What measurements will be used to define success? What is the minimum acceptable level of performance?

19 Guided Brainstorming Process Transform a challenge into a well defined inventive problem Define opportunities and generate preliminary ideas Evaluate ideas and develop solution concept Generate Ideas Develop Concepts Solution Challenge and Problem Steps 3: Formulate Opportunities Define Objectives Formulate Opportunities

20 Three Opportunities to improve Ideality: 1. Improve useful functions 2. Counteract harmful functions 3. Resolve the contradictions: Contradictory Function should produce a Useful result, and should not produce a Harmful result. ∞ Sum of Useful Functions Sum of Harmful Functions

21 Two sisters were fighting over the last orange. The mother steps in to settle the argument. How does she resolve the conflict? Dividing the Orange

22 She cuts the orange in two, and gives each sister half. A good compromise, but, is there a better solution? Dividing the Orange

23 YES! Resolve the conflict. Explore the needs of each. One sister ate the orange and threw away the peel. The other sister used the peel in a recipe, and threw away the orange! Clearly there is a solution which would delight both parties! Dividing the Orange
