Integrating the Concept of Affordance into Function-based Reverse- engineering with Application to Complex Natural Systems Abstract
The practice of reverse engineering is not only receiving increased attention in fields involving artificial systems such as computer software development, but also in fields involving natural systems such as molecular and cellular biology. As an example, a recent pronouncement of the National Academy of Engineering lists “reverse engineering the human brain” as one of the grand challenges for the next century. The applicability of engineering design principles to natural systems has been well recognized, but ambitious attempts to further reverse engineer such complex systems will require the latest advances in design thinking. The recent concept of design affordance readily lends itself to the analysis and understanding of complex natural systems that exhibit multiple interactions between subsystems.
Traditionally, reverse engineering has been based on the analysis of decomposing engineered systems into functional components. Recently, the concept of affordance, or what one system provides to a user, or to another system, has broadened the way engineers look at design. This paper attempts to provide an alternate method of reverse engineering that incorporates the idea of affordances. It is anticipated that this method will be particularly useful for illuminating our understanding of natural systems. By looking at the affordances of a system and the interrelationships illustrated by the affordance structure matrix, significant information can be obtained that might otherwise be missed if only considering functionality. Reverse engineering with respect to affordances should lead to a better understanding of not only the system, but also the purpose and plan behind it.
In addition, the introduction of reverse engineering of complex natural systems in the engineering curriculum provides a rich vehicle for making connections with several other fields of study, which engineering students would do well to consider. An example is developed which considers the system of life on Earth as a complex network of multiple interacting and interrelated subsystems. The integration of the concept of affordance into a function based reverse engineering approach is sketched. This approach provides additional insight into the system, which may lead to significant implications for the humanities and social sciences.
Reverse Engineering in the Undergraduate Curriculum
Much of modern engineering education typically involves the infusion of ideas from the humanities and social sciences in an effort to help engineering students communicate better, become more ethical, and see the task of engineering in a larger cultural context. This is as it should be, but is it possible that the field of design engineering might lend insight and wisdom back to the humanities? If engineering design principles are so helpful in unraveling the mysteries of biology, might they also be useful in the social sciences? These are just some of the questions being posed in an engineering elective course at Oral Roberts University (ORU), where undergraduate students wrestle with advanced concepts in reverse engineering. A recent article in ASEE Prism1 touts the benefits of having engineering students engage in the dissection of mechanical devices to reverse engineer the design thinking that went into their development.
