Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Triz shopping experience:

1. Compare - without doubt the biggest advantage that the Triz offers shoppers today is the ability to compare thousands of Triz at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Triz? Wrong! If the Triz is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Triz then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Triz? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Triz and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Triz wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Triz then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Triz site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Triz, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Triz, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

TRIZ () is a Russian language acronym for "Teoriya Resheniya Izobretatelskikh Zadatch" (Теория решения изобретательских задач), Theory of solving inventive problems or Theory of inventive problem solving. It was developed by Genrich Altshuller and his colleagues starting in 1946.

TRIZ is a methodology, tool set, knowledge base, and model-based technology for generating innovative ideas and solutions for problem solving. TRIZ provides tools and methods for use in problem formulation, system analysis, failure analysis, and patterns of system evolution (both 'as-is' and 'could be'). TRIZ, in contrast to techniques such as brainstorming (which is based on random idea generation), aims to create an algorithmic approach to the invention of new systems, and the refinement of old systems.

Introduction

Soviet engineer and researcher Genrich Altshuller believed that learning how to invent is feasible. He developed TRIZ, the theory and practice of the science of invention.

Since childhood, Altshuller showed his talents as an inventor. When he was just 15 years old he received his first certificate of the authorship of invention for an underwater apparatus. (The USSR did not issue patents to its citizens because it outlawed private property. Instead it issued certificates of authorship as an acknowledgement of the fact that a person is the author of an invention.) In 1946, at the age of 20, Altshuller developed his first mature invention - a method for escaping from an immobilized submarine without diving gear. In the late 1940s he worked in the "Inventions Inspection" department of the Caspian Sea Flotilla of the Soviet Navy in Baku. Altshuller's job was to inspect invention proposals, help document them, and help others to invent.

By examining a large database of his own and other people's inventions, Altshuller soon arrived at his most important observation: Inventing is the removal of a technical contradiction with the help of certain principles

To develop a method for inventing, he argued, one must scan a large number of inventions, identify the contradictions underlying them, and formulate the principle used by the inventor for their removal.

His results are being applied to solve creative invention problems not just within all branches of engineering, but within many other technical and non-technical fields as well.

TRIZ is sometimes used as a problem solving tool in Design for Six Sigma, (DFSS) a subset of Six Sigma which aims to design new products and processes for producing products with no more than 3.4 defects per million opportunities.

The effectiveness of TRIZ is in dispute in many Engineering circles. Claims by some inventors that they arrived at their inventions with the help of TRIZ cannot be independently verified. Very often managers try to introduce TRIZ into their organizations in order to not be blamed for failures (a kind of "due diligence" and a means of preventing such accusations as "why have you not used TRIZ ?")

Frequently, TRIZ is also sold to people outside of engineering disciplines as a way to 'produce' creativity in any field of human activity without any grounds for that and ignoring the fact that TRIZ is exclusively an engineering oriented tool.

History Altshuller began developing TRIZ methodology while working at the "Inventions Inspection" department of the Caspian Sea flotilla in Baku in the times of Stalin. By 1969 he reviewed about 40,000 patent abstracts in order to find out in what way the innovation had taken place. He eventually developed 40 Principles of Invention, several Laws of Technical Systems Evolution, the concepts of technical and physical contradictions that creative inventions resolve, the concept of Ideality (TRIZ) of a system and numerous other theoretical and practical approaches; together, this extensive work represents a unique contribution to the development of creativity and inventive problem-solving.

The tools developed under Altshuller's leadership were The different schools for TRIZ and individual practitioners have continued to improve and add to the methodology.

Effectiveness of TRIZ According to commercial promoters of TRIZ, as a collage of concepts and tools TRIZ has been employed by many Fortune 500 companies in the United States and abroad to solve manufacturing problems and create new products. These promoters claim that companies such as BAE Systems, Procter & Gamble, Ford Motor Company, Boeing, Philips Semiconductors, Samsung, LG Electronics, and many others have used TRIZ concepts to systematically solve complex technical problems. They also claim that the use of TRIZ has been expanding into other areas, and that TRIZ has been used successfully in biomedicine, medicine, computer programming, business management, etc. These claims cannot be independently confirmed.

Inventor David Levy, whose portfolio includes work on the functional layout of the Apple PowerBook, calls the methodology "tremendous." Though he does not use TRIZ formally, Levy says his practices naturally echo those found in the discipline. "The most exciting part about TRIZ is, it's not limited to how to make a widget," says Levy. "It's how to approach problem solving, it's how to approach Interpersonal relationships, it's how to approach society problems. It's really how to be creativity and to observe the world and solve problems."

TRIZ essentials Basic TRIZ terms:

Identifying a problem: contradictions Altshuller believed that inventive problems stem from contradictions (one of the basic TRIZ concepts) between two or more elements, such as, "If we want more acceleration, we need a larger engine; but that will increase the cost of the car," that is, more of something desirable also brings more of something less desirable, or less of something else also desirable.

These are called Technical Contradictions by Altshuller. He also defined so-called physical or inherent contradictions: More of one thing and less of another may be needed. For instance, a higher temperature may be needed to melt a compound more rapidly, but a lower temperature may be needed to achieve a homogeneous mixture.

An inventive situation might involve several such contradictions. The inventor typically trades one contradictory parameter for another; no special inventiveness is needed for that. Rather, the inventor would develop some creative approach for resolving the contradiction, such as inventing an engine that produces more acceleration without increasing the cost of the engine.

Inventive principles and the matrix of contradictions Altshuller screened patents in order to find out what kind of contradictions were resolved or dissolved by the invention and the way this had been achieved. From this he developed a set of 40 inventive principles and later a Matrix of Contradictions. Rows of the matrix indicate the 39 system features that one typically wants to improve, such as speed, weight, accuracy of measurement and so on. Columns refer to typical undesired results. Each matrix cell points to principles that have been most frequently used in patents in order to resolve the contradiction.

For instance, Dolgashev mentions the following contradiction: Increasing accuracy of measurement of machined balls without incurring in expensive microscopes and control equipment. The matrix cell in row "accuracy of measurement" and column "complexity of control" points to several principles, among them the Copying Principle, which states, "Use a simple and inexpensive optical copy with a suitable scale instead of an object that is complex, expensive, fragile or inconvenient to operate." From this general invention principle, the following idea might solve the problem: Taking a high-resolution image of the machined ball. A screen with a grid might provide the required measurement.

Laws of technical system evolution Altshuller also studied the way technical systems have been developed and improved over time. From this, he discovered several trends (so called Laws of Technical Systems Evolution) that help engineers predict what the most likely improvements that can be made to a given product are. The most important of these laws involves the ideality of a system.

Substance-field analysis One more technique that is frequently used by inventors involves the analysis of substances, fields and other resources that are currently not being used and that can be found within the system or nearby. TRIZ uses non-standard definitions for substances and fields. Altshuller developed methods to analyze resources; several of his invention principles involve the use of different substances and fields that help resolve contradictions and increase ideality of a technical system. For instance, videotext systems used television signals to transfer data, by taking advantage of the small time segments between TV frames in the signals.

ARIZ - algorithm of inventive problems solving Algorithm of Inventive Problems Solving (Russian acronym of Алгоритм решения изобретательских задач - АРИЗ) - Algorithm of Inventive Problems Solving - is a list of about 85 step-by-step procedures to solve very complicated invention problems, where other tools of TRIZ (Su-field analysis, 40 inventive principles, etc.) are not applicable.

Alternative approaches or creativity

There are several other approaches that purportedly help develop inventive power. Most of them are quite heuristical:

  • Trial-and-error
  • Brainstorming
  • Morphological analysis
  • Method of focal objects
  • Lateral thinking
  • ASIT (Advance Systematic Inventive Thinking)


    • TRIZ honours In the last year of his life Altshuller established a two-level form of certification:
  • a "TRIZ Master" Diploma, issued and signed by Altshuller; he granted it to several most proven persons in TRIZ community (according to his own list).
  • a "TRIZ Specialist" and "TRIZ Expert" Certificates, issued by International Association of TRIZ and signed by a TRIZ-master; these certificates are intended to be granted to people which need a confirmation of their credentials as TRIZ teachers (because people complained that without a certificate they faced obstacles in teaching TRIZ)


    • Some of the TRIZ-masters interpreted their title as a confirmation of their outstanding contribution to TRIZ, whereas others claimed that it was not exactly Altshuler's intent. (rus) The latter claim is based on the fact that the original list of masters did not include the well known outstanding contributors to TRIZ such as his wife Valentina Zuravliova, the co-author of SuField Analysis Irina Flikstein and many others simply because they have not been teaching TRIZ and have not been needing any kind of certification.

    After Altshuller's death some of TRIZ masters started promoting the first interpretation of the title and claiming to be heirs to TRIZ with a right to pass their diploma to their disciples (possibly saving an overall number of masters) and even claiming their entitlement to financial support from International Association of TRIZ (V. V. Mitrofanov is the most outspoken representative of such claimants (rus).) Others considered these claims as a devaluation and discreditation of the TRIZ-master title.

    To counter the inflation of a prestige of the TRIZ-master title and to foster the real TRIZ research, Anti TRIZ-Journal established Altshuller Prize for outstanding contribution to TRIZ. The Altshuller Prize Committee decided not to announce winners for 2006.
