“…Although the considered design strategies have general validity, some studies have also applied them in the field of eco-design and, sometimes, with the aim of favouring the CE (e.g., [21,22]). Furthermore, their effectiveness in reducing the environmental impacts has been positively estimated, both from a qualitative (e.g., [23,24]) and quantitatively point of view (e.g., [25]).…”

Different studies in the scientific literature have shown how the transition towards a circular economy (CE) can benefit from product design, although maintaining a rather broad and qualitative perspective of analysis. This study investigates and compares which product design strategies (from routinely design, structural optimization, industrial design and systematic innovation) are most used by students and professional designers to implement different CE strategies (i.e., waste reduction, reuse, remanufacturing, recycling and biodegradability). Students’ data were collected from year projects and MSc degree theses based on real industrial case studies and carried out in two Italian engineering universities, while those of professional designers, were collected from selected scientific articles. Among the main outcomes emerged that the design strategies deriving from systematic innovation were preferred by students quite clearly. The design strategies referred to industrial design, e.g., user-centered design and timeless design were preferred by professional designers. The design strategies related to routine design, i.e., materials substitution, reducing resources and energy consumption, and structural optimization, were indistinctly used by both students and professional designers. The obtained results and their discussion can be useful during eco-design teaching to show the main gaps that students should fill in comparison with professional designers.

“…Fiksel (2009) in his book "Design for environment" gathered an exhaustive list of tools and methods used for different industries and purposes but missed to provide a universal systematic methodology for problem solving. Some researchers have found that the various classical TRIZ tools are effective in solving design problems and in improving product eco-efficiency (Lim 2016). Others work consists of establishing a link between Eco-efficiency elements and TRIZ principles (Sheng and Kok-Soo 2010), while others focused on the resolution of multiple-contradiction eco-efficiency problems (Chang and Chen 2004).…”

This article presents a workflow to solve multi-contradiction problems for natural processes, in an eco-friendly way, using the Eco-innovation Elements and TRIZ (the theory of inventive problem solving). The suggested workflow is based on a mixture of the most popular TRIZ tools and the elements of Eco-innovation, it starts with a problem context analysis and scope definition, and it ends with a sequential brainstorming and evaluation of the solutions. The Ideal Final Result (IFR) tool is used as a comparison element to assess the solution. The method handles all the contradictions in a prioritized way, giving more chances for the solution to converge toward the IFR. The method aims to bypass contradictions instead of finding consensus. Indeed, as it is described, the workflow brings systematic step-by-step procedures to solve complex problems and differs from other toolsets that leave the choice to the solver's convenience.

“…Some authors suggested that TRIZ tools are most suitable for improving the sustainability of a phase of the product lifecycle and/or a specific problem or strategy. The Evolution Trends (e.g., Dematerialization) are used by [24] for improving the design phase through mass reduction and geometry modification, while the Contradiction Matrix and the Principles are exploited by [25] and [26] for improving the use phase (i.e., reducing consumption) and by [27] and [28] for the end-of-life (i.e., disassembly).…”

“…According to [24], solutions deriving from the same TRIZ tools (i.e., the trends of evolution) and concerning different aspects (e.g., materials and aesthetics) are better in certain cases than traditional solutions. While [25] instead positively evaluated the solution by limiting only to the use phase of the product lifecycle or assessing a reduction of the consumption without considering the impact deriving from their implementation during manufacturing. Finally, there is also the negative qualitative assessment concerning the perception of the sustainability of those TRIZ-derived solutions, which typically ignore social aspects about sustainability, e.g., marketing and packaging aesthetics [20].…”

TRIZ-Based Guidelines for Eco-Improvement

This paper proposes a set of Eco-guidelines for supporting designers in developing new greener products and processes. The first requirement that a guideline should have is to be sufficiently general to cover every kind of problem and at the same time sufficiently specific to bring the user closer to the solution without requiring too much personal inspiration. This balance was searched by adopting one of the most known systematic innovation techniques: TRIZ (Russian acronym of Theory of Inventive Problem Solving). In the literature, there are many examples of integrations between Eco-guidelines and problem-solving methods, but the solutions that are suggested, however effective, are not necessarily eco-friendly. To overcome this problem, the authors propose a rigorous ontology indicating how to apply a specific problem-solving strategy onto a specific part of the problem, trying to make the user aware of the environmental consequences of his design changes. The result of this work is a set of 59 guidelines. The article explains the birth of each guideline, the way in which they were adapted with respect to the known technique, and the motivation for which they should generate greener solutions, in light of the results of an experiment involving engineering students in real industrial cases.
