Design by Analogy to Nature Engine

About

Biologically inspired design, a kind of design by analogy, requires that engineers understand complex biological systems as analogues for design. A number of typical characteristics make biologically inspired design an especially interesting problem to study. (1) By definition, biologically inspired design is based on analogies requiring expertise across two disparate domains (e.g. architecture and biology), and thus is inherently interdisciplinary. (2) Since the objects, relations and processes across domains are very different, design collaborators speak from different lexicons. (3) Since biologists in general seek to understand the functions of designs occurring in nature whereas designers generally seek to generate designs for human needs, they use different methods of investigation and have different perspectives on design. (4) The resources, such as materials and processes, available in nature to realize an abstract design concept are very different from the resources available in the human domain.

Despite many pioneering and valiant efforts, the fact is that at present there is no science of biologically inspired design, and its practice remains scattered, empirical, and ad hoc. This raises many basic questions such as: How do biologists and engineers work together in teams? How do they generate new design ideas? How do they understand biological systems? What external knowledge representations of biological systems may help deepen their understanding? What should we teach in courses on biologically inspired design and how should we teach it? While these questions are critical to developing a science of biologically inspired design, they also provide a great opportunity to explore fundamental questions about cognition.

The Systems Thinking project at the Design & Intelligence lab broadly focuses on teaching students at various levels to engage in thinking about complex, and especially ecological, systems. The project specifically addresses multiple specific tasks and abilities:

• Helping students understand complex systems through the construction of structure-behavior-function models (Goel et al. 2010; Goel et al. 2013).
• Providing feedback on model construction through dynamically-generated invokable simulations based on conceptual models (Vattam, Goel, & Rugaber 2010; Joyner, Goel, & Papin 2014).
• Facilitating the broader process of scientific inquiry, grounded in model construction (Joyner, Majerich, & Goel 2013).
• Providing personalized feedback on modeling and inquiry through metacognitive tutoring agents (Joyner & Goel 2014).

The Systems Thinking project has been under active development for over ten years. Over one thousand students have used the tools constructed within the project. The first of these tools, the Aquarium Construction Toolkit (ACT), allowed students to construct structure-behavior-function models of aquaria based on investigation of a classroom aquarium. The second tool, the Ecological Modeling Toolkit (EMT), built and expanded on ACT by generalizing the construction of models out into various ecological systems, such as ponds, lakes, and estuaries. The third and current tool, the Modeling & Inquiry Learning Application (MILA), augments the modeling process with multiple tools for inquiry to facilitate model-based inquiry in addition to modeling alone.
