  • BioTRIZ approach was proposed and published 10 years ago ( and is developed much further than simple examples. Authors of this slide-show should get more skills in revealing the contradictions, but examples are generally good. Please do remember that examples are not a method. TRIZ itself works well ONLY if a problem definition is done right - contradictions and inventive principles never work separately from the algorithm or give too general and therefore not so useful solution. BioTRIZ Ltd ( provides full training in REAL METHOD of how to transfer biological effect into implementation in technology since 2006.

  1. 1. Biomimicry Tools NCIIA 2012 1 Extending the TRIZ Methodology to Connect Engineering Design Problems to Biological Solutions Jonathan Weaver1, Darrell Kleinke1, and Terri Lynch-Caris21 University of Detroit Mercy Mechanical Engineering Department 2Kettering University Industrial Engineering Department
  2. 2. Biomimicry Tools NCIIA 2012 2 Outline • The Need • Triz from 35,000 ft • Handling Physical Contradiction • Handling Technical Contradiction • Blending Biomimicry and Triz • Conclusion & Invitation to Collaborate
  3. 3. Biomimicry Tools NCIIA 2012 3 The Need • Some engineers are versed in TRIZ and routinely apply its methodologies when trying to innovate • Others look to nature for inspiration • Both approaches can be effective, yet very few are well- versed in both approaches • We propose a framework to extend the TRIZ methodology to point engineers to not only relevant man-made examples, but also to potential inspiration from nature
  4. 4. Biomimicry Tools NCIIA 2012 4 TRIZ from 35,000 feet • Tough problems typically involve contradictions • A contradiction can be either physical or technical • Physical contradiction involves a conflict between two mutually exclusive physical requirements to the same parameter of an element of the system (i.e., an element should be hot and cold) • Technical contradiction involves a conflict between characteristics within a system whereby improving one parameter of the system results in deterioration of another parameter (i.e., increasing power also increases mass)
  5. 5. Biomimicry Tools NCIIA 2012 5 Handling Physical Contradiction • Altshuller recommends considering four principles: – Separation of contradictory properties in time or on condition – Separation of contradictory properties in space – System transformations (or separation between the parts and the whole) – Phase transformation, or physical-chemical transformation of substances
  6. 6. Biomimicry Tools NCIIA 2012 6 Approach for Handling Technical Contradiction • Using the set of 39 engineering parameters, state the contradiction in the form improving [first parameter] causes deterioration of [second parameter] • Use the Contradiction Matrix to identify which of Altschuller’s 40 Inventive Principles seem most likely to assist in resolving the contradiction • Study past manifestations of the suggested inventive principles and try to tailor a solution to the problem at hand

  11. 11. Biomimicry Tools NCIIA 2012 11 Our Approach to Blending Biomimicry and Triz • The proposed Bio-TRIZ methodology would automatically connect anyone utilizing the TRIZ methodology to potentially relevant biological inspirations. • Rationale: innovators applying the TRIZ methodology are likely to come up with a richer, stronger, and more diverse set of product concepts if they are simultaneously presented with inspiring biological examples of relevant inventive principles alongside the classical manmade examples and patents. • The proposed approach will be outlined first for resolving physical contradiction, then for resolving technical contradiction.
