  12. 12. Biomimicry Tools NCIIA 2012 A perspective from the literature Function mapping has not gained industry wide acceptance like some other techniques such as TRIZ. Dieter (2009): “There are weaknesses in using functional structures during conceptual design. A function structure is not a complete conceptual design. Even after developing a function structure, you still need to select devices, mechanisms, or structural forms to fulfill the function. There are no comprehensive catalogs of solution embodiments like those available in the German technical literature.”

  17. 17. Biomimicry Tools NCIIA 2012 Conclusion • Function mapping has the potential to become the link between engineering design problems and biological solutions. • If standardized and codified, function mapping becomes easier to use and can represent a common practice that could cross numerous diverse engineering and biology disciplines. • Function maps can be formulated by engineer and biologist alike, and can become the common link to connect biomimicry and engineering design.
