Sustainability Patterns

  • Yael Helfman Cohen

In this chapter, we offer the concept of Ideality as a framework to guide the search for sustainability patterns in nature. Ideality in TRIZ is a qualitative ratio of systems benefits to costs. We discuss the relation of ideality and sustainability, provide ideality analyses of biological systems, and present the ideality bio-inspired tool for sustainable design, based on ideality strategies that repeat in nature. We present a detailed case study of multiphase bicycle design challenge, addressed by the ideality tool, and demonstrate how this tool served as sustainable innovation leverage. We discuss the ideality tool in a broader scope of DFE (Design for the Environment) and bioinspired sustainability tools and demonstrate how it enriches the life principles with new insights and operative principles.
