The paper focuses on the identification and resolution of conflicts and contradictions in complex systems. By constructing simple, computerbased bottom-up models of an exemplar complex system, we show the potential for the emergence of multi-phase macro-level outcomes. We then show how these discontinuous phase-shifts may be modelled as contradictions, and from there, how TRIZ tools can be used...

This paper describes design principles that were extracted from the profiles of products redesigned to be more environmentally benign. These extracted principles will be used to support the work of creating a Design for Environment (DfE) methodology called ENVRIZ that provides product designers with a procedure for creating more environmentally benign products and overcoming environmental contr...
