  • A Simple Theory Underlying Structured, Problem-Solving – ASIT, TRUZ, USIT and Others Ed Sickafus Thinking and teaching are different. Introspection of our personal thinking procedures reveals that our mental processes are not as logically organized as is the teaching of structured-problem solving. Recognition of this difference can open our minds to adopting new innovative applications of structured problem-solving tools.
  • A Simple Theory Underlying Structured, Problem-Solving – ASIT, TRUZ, USIT and Others Ed Sickafus The structure of structured problem-solving methods can misdirect our emphasis on the need of organization in learning and applying these methods.
  • A Simple Theory Underlying Structured, Problem-Solving – ASIT, TRUZ, USIT and Others Ed Sickafus By recognizing that emphasis on organization can distract or divert our natural mental capabilities we can begin to focus on engaging more of our mental resources toward innovative thinking. Distractions waste time during the very rapid process of intuitive thinking.
  • A Simple Theory Underlying Structured, Problem-Solving – ASIT, TRUZ, USIT and Others Ed Sickafus We have two brains, designated as the left-hemisphere (LH) and the right-hemisphere (RH). LH and RH are used here in reference to language residing in the LH. This is not the case for everyone. You may need to exchange LH and RH as you read this discussion. Typically (LH:RH::6:1) most people are LH (ca. 17 % are RH)
  • A Simple Theory Underlying Structured, Problem-Solving – ASIT, TRUZ, USIT and Others Ed Sickafus It is the product of logical thinking – an LH trait.
  • A Simple Theory Underlying Structured, Problem-Solving – ASIT, TRUZ, USIT and Others Ed Sickafus Analysis, definition, and solution are logical steps that mollify LH’s demands. Testing of the first idea that comes to mind appeases the intuitive nature of RH. RH’s intuitive insights may seem to be interruptive to LH’s overview of logical continuity and thoroughness. LH could demand structure to guarantee its preferred procedure. But thoroughness does not require strict continuity.
  • A Simple Theory Underlying Structured, Problem-Solving – ASIT, TRUZ, USIT and Others Ed Sickafus By de-emphasizing order we free our minds for more RH activity while LH assures that thoroughness is achieved.
  • Patent Analysis: Initial analysis of 200,000 patents were synthesized down to just innovative patents, not all patents were considered innovative by Altshuller. These 40,000 patents were analyzed and the following Key Discoveries were found. Initially these patents focused on mechanical, thermo-mechanical, thermo-electrical, etc Altshuller recognized that the same fundamental problem had been addressed by a number of inventions in different areas of technology He also observed that the same fundamental solutions were used over and over again, often separated by many years He reasoned that if the latter inventor had had knowledge of the earlier solution, their task would have been straightforward He sought to extract, compile & organize such information
  • First he trial ask some inventors and try to understand how they can do inventions. Soon he understand that this is the wrong way. He start to investigate history of engineering system and patent descriptions. And he arrived at the conclusion that there are objective laws of engineering system evolution. And good idea is idea that conform to the objective laws. This objective laws is the main things that control of systems evolution , so they can show us direction of problem solving. Using this idea Altshuller produce Algorithm for engineering problem solving - ARIZ. Он решил несколько задач вместе со своим другом и они написали письмо Сталину. Какова была реакция государства? Каков результат? Как вы думаете? После этого они получили по 25 лет ГУЛАГА.
  • Our first task is to state Ideality. While the most Ideal solution would be to eliminate the defects, for our purposes that is out of scope. Ideality would be that “ the pills sort themselves.” We then need to look for resources to accomplish this.


  • 2. They way we think during structured-problem solving differs from the way it is taught. Understanding this difference and how we use our mental resources can aid our innovative application of any structured methodology.
  • 3. Structured problem-solving methods are logical and organized while our natural thinking is not. Assumption A cause of methodology complexity is its logical idealization as compared with our natural method of thinking.
  • 4. Our innovative problem-solving skills can be improved with more natural thinking and the use of all our thinking resources.
  • 5. Two halves of our brains think Both perform reasoning, remembering, communication, and problem solving. But they do them differently and share their results. Example: One is better at logic and the other better at understanding metaphors.
  • 6. Communication of problem solving is orderly, like this … Definition Solution Analysis
  • 7. Typically, we begin with an immediate, intuitive, solution concept. It is tested and modified iteratively as necessary for acceptance or rejection. Idea Solution Analysis Definition Solution Definition Analysis Idea Idea Idea
  • 8. From this observation we learn that in our natural mode of thinking, while problem solving, the content of structure is important not its order. LH RH

  • 12. Origin of TRIZ
    • Problems & solutions were repeated across industries & sciences  Principles for solving Problems
    2. Patterns of technical evolution were repeated across industries & sciences  Technology Trends to evolve a technical system to the next generation 3. Innovations used scientific effects outside the field from where the original problem was found  Scientific Effects can be used to solve problems in unique ways Key Discoveries
    • Today, the followers of Altshuller
    • have analyzed / investigated over 2,800,000 patents
    200,000+ Analysis of Patents* 40,000 Innovative Patents Synthesized down to just Innovative Patents
  • 13. TRIZ
    • TRIZ: A Theory of Inventive Problem Solving (abbreviated in Russian)
    • Result of 40 years of research of more than 300 people (and still evolving)
    • TRIZ makes innovation systematic while preserving a capability to freely use human creativity.
    • TRIZ does not replace traditional method for innovation, it adds value to the existing methods and practices
    • Since TRIZ has been brought outside of the ex-USSR in 1990th, it is today recognized by several world-leading organizations such as Boeing, Lockheed Martin, NASA, Procter & Gamble, Samsung, Mitsubishi as the best practice of innovation
  • 14. They use TRIZ
  • 15. TRIZ – Theory of Innovative Problem Solving Be a systematic step by step procedure. { Teoriya Resheniya Izobreatatelskikh Zadatch } Founding Principle.. be repeatable and reliable
  • 16. Founding Principles be able to access the body of inventive knowledge TRIZ be able to add to the body of inventive knowledge be familiar enough to inventors
  • 17. Altshuller studied patents. 200 K Patents.. TRIZ
    • Found that only a small portion are true innovations
    • Remaining are straight forward improvements
    Today it is 1.4 Million Patents.. he then classified these patents
    • Many industries or technologies face the same generic type of design problems.
    • It’s almost impossible to cope with all areas of technology, read all literature,….
    • Accidents or alerts sometimes change this
    • It is helpful to be aware of problem solving principles used by everyone
  • 19.
    • Triz is both a mental process and a science, as well as a selection of tools in a tool kit
  • 20.
    • Why Innovation???
    • Who remembers one of SABIC values?
    • Our commitment to continuous improvement and innovation ensures quality products, excellent services, and satisfied customers.
  • 21. Why Innovation??? In our full cost environment and the strong emphasis to contract out, we must be innovative if we want to stay relevant and keep funding coming in.
  • 22. Pattern Thinking the secret of genius
  • 23. Pattern Thinking is about finding repeating patterns list elements There is always a pattern …. … . always! find the pattern
  • 24. An Innovation Methodology
    • Develop a Strategy Pattern to create focus
    • Use Forced Innovation Technique to create the artefact(s)
    • Use Deliberate Evolution to plan and stage implementation
  • 25. G. Altshuller What is TRIZ ? TRIZ is a tool for thinking but not instead of thinking
  • 26.
    • Why TRIZ?
    • There are several methods for increasing innovation.
          • Brainstorming
          • Synectics
          • Lateral Thinking
          • Neurolinguistic Programming
          • Mind Mapping
    • These are all emotionally based.
  • 27. Why TRIZ? TRIZ is empirically based!! It is designed to overcome Psychological Inertia. Psychological Inertia is based upon habits, our education, paradigms, internal processes, past successes, past failures and “we have always done it that way”. TRIZ directs the solution path based on an empirical approach to the problem resolution.

  • 33. Why difficult?
    • Problems are difficult due to:
      • Strong mental inertia which prevents us from thinking “out of the box”
      • Lack of problem solving strategy
      • The needed knowledge to solve a problem can be outside of our specific domain of knowledge
      • To solve a difficult problem, it is always necessary to generate many alternatives with trial & errors method

    • Principle 8. Anti-Weight
    • A. To compensate for the weight of an object,
    • merge it with other objects that provide lift.
    • Inject foaming agent into a bundle of logs, to make it float better.
    • Use helium balloon to support advertising signs.
    • To compensate for the weight of an object,
    • make it interact with the environment
    • (e.g. use aerodynamic, hydrodynamic, buoyancy and other forces) .
      • Aircraft wing shape reduces air density above the wing,
      • increases density below wing, to create lift.
      • (This also demonstrates Principle 4, Asymmetry.)
      • Vortex strips improve lift of aircraft wings.
      • Hydrofoils lift ship out of the water to reduce drag.

    • Principle 9. Preliminary Anti-Action
    • A. I f it will be necessary to do an action with both harmful and useful effects, action should be replaced with anti-actions to control harmful effects .
      • Buffer a solution to prevent harm from extremes of pH.
    • B. Create beforehand stresses in an object that will oppose
    • known undesirable working stresses later on .
    • Pre-stress rebar before pouring concrete.
    • Masking anything before harmful exposure:
    • Use a lead apron on parts of the body not being exposed to X-rays.
    • Use masking tape to protect the part of an object not being painted

    • Principle 12. Equi-potentiality
    • In a potential field, limit position changes
    • (e.g. change operating conditions to eliminate the need
    • to raise or lower objects in a gravity field).
      • Spring loaded parts delivery system in a factory
      • Locks in a channel between 2 bodies of water (Panama Canal)
      • "Skillets" in an automobile plant that bring all tools to the right position
