“TRIZ” BRINGING SCIENCE TO PRODUCT DEVELOPMENT
Tampa PDMA Chapter 4/30/08 Jack Hipple Innovation-TRIZ Tampa, FL 813-994-9999 www.innovation-triz.com
OBJECTIVES
Change the way you think about NPD
Take some of the guesswork out of NPD
Provide some simple tools for use
A NPD BRAINSTORMING SESSION …LOTS OF IDEAS, NO JUDGING
The rule of brainstorming and Creative Problem Solving----
CONTINUED….
WHAT IS “TRIZ” ?
A Russian acronym: Theoria Resheneyva Isobretatelskehuh Zadach (Theory of Solving Inventive Problems
THE HISTORY OF TRIZ
Discovery of brilliant Russian patent examiner— Genrich Altshuller--1950’s Studied thousands of the world’s most inventive patents (<5%)--now in the millions---what used in the invention?
There are only so many!!
Map problems to known solutions principle was Recognized development of products and systems follow predictable patterns that cut across ALL areas of technology- accelerated speed of technical evolution can be New product development and problem solving are sciences and not based on simply luck or psychological stimulation: anyone can invent! Anyone can be a better inventor or problem solver!
Technology emigration to the West~1990
IT’S ROME, 1100 A.D.
NO ONE HAS “INVENTED” ALGEBRA
QUICK
: WHAT’S “X” Specific problem 3 x 2 +5 x +2 = 0 Specialized solution x = ????
GENERALIZING PROBLEMS AND PROBLEM SOLVING PRINCIPLES: THE BASIS OF TRIZ
Abstract problem ax 2 Problem Solving Principle Example +bx+c = 0 Abstract solution x=(-b+/ b 2 -4ac)/2a
THIS IS THE TOUGH PART!
Specific problem Specialized solution 3x 2 +5x+2 = 0 x= -1, -2/3
TRIZ DOES FOR PRODUCT DESIGN AND FORECASTING WHAT ALGEBRA DOES FOR EQUATION PROBLEM SOLVING!
THE OLD WAY BRAINSTORMING, CONSUMER SURVEYS, AND : TRIAL AND ERROR THE
NEW WAY
: USE
PATTERNS PREDICTIVE
PRINCIPLES AND KNOWLEDGE AND
DIAMOND CHUNKS TO DIAMOND DUST: THE MACHINE TOOL INDUSTRY NEEDS YOU!
HOW?
*
PATTERNS OF INNOVATION Processing Sweet Peppers
WHAT IS THE INNOVATION PRINCIPLE WE USED?
“Slowly raise pressure and suddenly reduce it” or “ slowly store energy and suddenly release it HARM?) ” (concept of an electronic capacitor?)—where else used? (PREVENTING A SURGE OF NEGATIVE ENERGY TO PREVENT
An approach to solving a problem AN INVENTIVE PROBLEM SOLVING PRINCIPLE
THE
SAME
INVENTIVE PRINCIPLE
• • • • • • •
Removing stems from bell peppers (1945) Removing shells form sunflower seeds Cleaning filters Unpacking parts wrapped in protective paper Splitting diamonds along micro-cracks (1972) (+27 years after pepper patent) Producing sugar powder from sugar crystals Explosive depulping
HOW CAN WE IMPROVE A CAR HEADREST?
YOU’D LOOK IN THE BASEBALL LITERATURE—WOULDN’T YOU?
NOTE THE DIFFERENCE IN THINKING BETWEEN…
How do I minimize the damage from the impact of the human head against a headrest vs.
How do I cushion and stop without harm a moving object that suddenly stops? Where else does this happen?
HOW LONG HAVE CATCHERS’ MITTS BEEN AROUND?
WHEN DID CAR SEATS FIRST GET HEAD RESTS?
WHEN WE STUDY ALL THESE INVENTIONS….
We find:
Limited number of inventive principles and general patterns of product development that apply universally
Breakthrough products and inventions come when a contradiction is resolved
TAKEAWAY #1:
DUMP YOUR EGO!
YOU ARE NOT ALONE IN THE UNIVERSE—THE CHALLENGE YOU HAVE HAS ALREADY BEEN SOLVED—IN A GENERAL SENSE!
CAVEAT: Emotional aspects
Color Reminds me of….
“Feels good” “Tastes good”
PROBLEMS WITH THE OLD WAY: MARKET SURVEYS
Customers can’t express what they don’t think is possible They are not aware of discontinuous technologies “Pointers/Indicators” “Communication” Improve what I have Smoother wood, more compact metal pointer, etc Less confusing smoke signals, faster telegraph, etc.
PRODUCT AND SYSTEM EVOLUTION
Products and systems become more ideal with time
Added functionality Trimming (“something performs its function and doesn’t exist”) Contradictions are resolved
Contradiction table Separation principles Systems become more dynamic with time Systems use higher level fields Products and functions are integrated into their super-systems ALLOWS PREDICTIVE FORECASTING
A MAJOR BARRIER…
Jargon Ease of communication within industry Barrier to inventive problem solving
WHAT ARE EXAMPLES OF YOUR JARGON?
EXPLAIN TO A 10 YR. OLD THIS WILL HELP YOU LOOK FOR MODELS AND SOLUTIONS IN PARALLEL UNIVERSES
TAKEAWAY #2:
GENERALIZE: STOP USING JARGON IN PRODUCT DEVELOPMENT
USE FUNCTIONAL LANGUAGE
WHAT DO YOU WANT “XXXX” TO
DO? NEED DONE?
SPECIFIC TOOLS FROM TRIZ STUDIES/ALGORITHM
SYSTEMS AND PRODUCTS BECOME MORE IDEAL OVER TIME
What’s “ideal”?
Ratio of useful functionality/ negative effects (Good stuff/bad stuff!) Added functionality Trimming
within a give a system No contradictions, no negative side effects, etc.
Hard to state, but we must start here even though we might not get all the way there!
SOMETHING PERFORMS ITS FUNCTION WITHOUT EXISTING!
ADDING FUNCTIONALITY: CLEAN THE SHOWER WHILE YOU SHOWER!
ADDED FUNCTIONALITY
HOW COMPLEX CAN A SHOE GET?
USEFUL COMPLEXITY!
A MORE “IDEAL” ALARM CLOCK
TAKEAWAY #3:
HOW CAN YOU ADD USEFUL COMPLEXITY TO YOUR PRODUCT OR SERVICE?
TRIMMING: AN IDEAL PRODUCT/SERVICE THINKING TECHNIQUE
Arbitrarily remove part of a system and ask how its function can be performed with the remaining parts of the system Dyson Vacuum Cleaner
THE TOOTHPASTE TUBE PERFORMS ITS FUNCTION WITHOUT EXISTING, USING THE RESOURCES ALREADY PRESENT
THE NEW FIREPLACE: DVD PLUS ELECTRICITY
THE “TWEEL”—CATERPILLAR: THE WHEEL PERFORMS ITS FUNCTION AND DOESN’T EXIST HOW DOES IT FEEL TO BE GOODYEAR? UNIROYAL?
TAKEAWAY #4:
“TRIM” SOMETHING FROM YOUR PRODUCT/SYSTEM/SERVICE WHAT NEW IDEAS/BUSINESS CONCEPTS PRESENT THEMSELVES?
A THIRD APPROACH: RESOLVING CONTRADICTIONS
SYSTEM EVOLUTION— “ JOINING” THINGS Infinitely re

THE BICYCLE: MORE IDEAL THROUGH CONTRADICTION RESOLUTION 1815: No pedals or breaks 1840: Pedals—more speed 1845: Brakes (more speed also requires ability to stop!) Wheel diameter increased: more speed 1870: Metal wheels replace wooden wheels 1885: Chain transmission: eliminate need for one large wheel 1888: Pneumatic tire: more speed 1890: Clutch
THE CAR
Motor Brakes Tires Shocks Steering Gears/transmissions Variable transmissions Heating/AC Etc.
CONTRADICTIONS— THE JET ENGINE
Boeing wanted to install larger engines on a redesigned 737. A larger air intake would reduce ground clearance to unacceptable levels.
Contradiction: Increasing air intake reduces ground clearance Control parameter: Intake radius
CONTRADICTIONS – JET ENGINE
Resolve the contradiction by
Asymmetry
Make the radius large laterally for high air flow.
Make the radius smaller downward for high ground clearance.
LOOK AT SEPARATING IN….
Space Condition Parts/whole Time
TAKEAWAY #5:
IDENTIFY ALL YOUR CONTRADICTIONS (YOUR PRODUCT, YOUR CUSTOMERS’) RESOLVE THEM!
DON’T COMPROMISE!
PRODUCT AND SYSTEM EVOLUTION
TRIZ Lines of Evolution Ex:
Systems become more dynamic with time Systems use higher level field
Mechanical, thermal, chemical, electronic, electromagnetic
“Communication”, “pointers”, “idea capture”

TAKEAWAY #6 : UNDERSTAND KNOWN EVOLUTIONARY PATTERNS AND LET THEM DRIVE YOUR PRODUCT PLANNING AND CONSUMER RESEARCH
Ex: more dynamic (to what?), MeThChEEMO
MAPPING PRODUCT DEVELOPMENT AGAINST LINES OF EVOLUTION
‘Evolutionary Limit’ of component relative to predicted evolution trends Current evolutionary position of component for a given trend (Each spoke in the evolutionary potential radar plot represents one of the known technology trends identified by TRIZ researchers)
AN IDEAL PRESCRIPTION BOTTLE: ALDER/TARGET STORE PHARMACIES
Pills or liquids Name on top Red color: caution Hierarchy of information Upside down: wrap around bottle, saves paper Secondary color rings
How could this be improved further?
