Not Exactly !

people reject good solutions and invest in bad ones becausebecause they do not know the difference between them.

People can take one of two positions

• It is not possible to know whether the idea is good or bad when it is first proposed.

• Because the same patterns are repeated, we can learn from the past to get better solutions today.

There is growing evidence supporting position 2, using TRIZ to provide the general theory of the evolution ofgood ideas.

Common Features of Good Solutions

• Resolves contradictions

• Increases the ”ideality” of the system

• Uses idle, easily available resources

Two Models

Rationalized or hard model : Theory X : Demand Pull

• R&D centers are established

• The work is controlled by budgets and time limits.

• People need to be controlled tightly

• Management helps to get minor improvements

• Seldom gives great, qualitatively new ideas

Humanized or soft model : Theory Y : Science Push

• People naturally have imagination and creativity

• External control is not the only means for good results

• Criticism and control are minimized or prohibited

• Fantasy, feeling, play, intuition, and pleasure are encouraged

Which approach is better ?

Inventive methodologies in industry seem to oscillateperpetually between hard and soft models. Both ways are blindalleys

Existing Problem solving Tools don’t give specific techniques

• Quality Function Deployment (QFD): No tools to meetclient’s contradictory requirements

• Theory of Constraints (TOC): Recognizes conflicts but Notools to resole them

• Six Sigma: begun incorporating TRIZ to get good solutions tothe problems that were identified

theory of inventive problem solving

TRIZ is a global theory, originated in erstwhile Soviet Union

• Founded by Genrich Saulovich Altshuller (1926-1998)

• Confined in prisons and camps most of his lifetime in Baku

• In research on millions of patents he found common patterns ofevolution

• inventor can learn these patterns to develop new technology

• Consciously, systematically and without many fruitless trials anderrors

• TRIZ boom rose in the United States, Japan, and many othercountries

TRIZ

• TRIZ is innovation by rapid, systematic process

• Structured approach to problem solving

• Much more powerful and complete than brainstorming, etc.

3 Key Findings

• Problems and solutions are repeated across industries & sciences

• Patterns of technical evolution are repeated across industries &sciences

• Best innovations occur when scientific effects are used from outsidethe field where the original problems were developed

TRIZ Addresses These Barriers to Problem Solving

• Shortage of individual knowledge

• Lack of problem solving resources

• Avoiding contradictions

• Psychological inertia

Contradiction

Difficult Problems Contain Contradictions

A contradiction is a conflict in the system. A system consists of twocomponents: tool (T) and object (O)

Ax blade to cut wood

• The edge of the ax blade,is a tool that splits the object, a chunk of wood

• If you make the blade heavier, the ax can strike a more effective blow, but it becomes more awkwardto handle

A company wants to improve customer service by increasing staff training

• Training is the T that is used to improve a certain O: the professional quality of employees

• For better service, more training time is needed but the time loss might be intolerable

The seesaw analogy of the problem situation

TRIZ advises us NOT to avoid contradictions

• It reverses the logic - find the contradiction, intensify itand resolve it without compromise

• Contradictions between tools and objects are the movingforce of evolution

Resources

Using resources, one can remove the contradiction and get the idealfinal result

Resources are things (including waste), information, energy, orproperties of the materials that are already in or near theenvironment of the problem

Resource has the functional and technological ability to jointlyperform additional functions


Blade, its edge, form, material, and other properties; the handle and its properties; the chunk of wood and itsproperties; the surrounding air; the person; etc.


The curriculum, its structure and properties, skills of teachers, textbooks, the motivation, and existingknowledge and skills of the students are all resources, as well as the culture of the company and the physicalenvironment of the training

Ideal final result

If the child’s resources included some rope, a tree, and a strongparent, both ends of the plank could go up at the same time


• Something changes the ax in some way so that it is both heavy and light, for the double purpose ofmaking the blow stronger without decreasing the ease of use

• Hollow Handle : Air is used as the resource that solves the problem

• The center of gravity moves nearer to the blade. The blow is more powerful, which could be thoughtof as heavy, although the tool is lighter.


• Changing the training so that part of it is done on the job, not in the classroom

• Better learning as well as shorter classes, because the students can see the results immediately andare in a better position to apply them

• Improves both motivation and feedback

• The function is often performed using existing resources

Ideality Example

Ideal Air Freshner for Rest rooms

It Does not Exist

Solution : Ideal Air Freshner for Rest rooms

• New fluorescent light bulb Fresh2 is a device that safely breaksdown odors, while providing light, a healthy alternative totraditional chemically based air fresheners

• When you turn on light, then Fresh2 begins eliminating odors dueto UV rays that trigger a photo catalytic process in titanium oxidecoating

• Since it’s a compact fluorescent bulb, it will serve longer thenconventional incandescent lamp and save money in deodorizers andin energy costs

Patterns of evolution

Important regularities in the development

Transition to microlevel or macrolevel


• The ax can be segmented or divided into parts : molecules : Hollow axe

• A stream of particles, as with a sandblaster, can be a very effective cutting tool, where each particlecould be considered a microax


• A training program can be segmented (transition to microlevel) and integrated to larger systems(transition to macrolevel)

• For better service, more training time is needed but the time loss might be intolerable

To grip workpieces of complex shape, vice jaws must have acorresponding shape. It is expensive to produce a unique toolfor every workpiece, however

Vise with ordinary jaws, but add multiple hard bushings

• separation between the whole and its parts recommends that we assign one of the contradictoryrequirements to the whole system and the other to its parts, as follows
