###### Abstract
In this way, it is possible to make an assessment of the evolution of their design during their various stages of conception, in ecological terms, that is, eco-design [15]. This tool was selected due to its compatibility with the matrix of contradictions belonging to TRIZ, allowing to explore their joint application and the bridge that is created in order to overcome the limits that each of these tools present. Several studies have addressed and linked TRIZ with sustainability in a wide range of areas and applications, from eco-innovation to social sustainability and ergonomics. In [16], the authors propose, in order to achieve more environmentally friendly and sustainable buildings, different possibilities to model green roofs related problems with distinct TRIZ tools. Eco-design has also been a topic of interest in which TRIZ tools are used to ensure that sustainable results are embed into everyday design practice [17], and these tools are used to assess if the value of existing solutions can be improved according to sustainability requirements. Additionally, regarding Eco-design, a TRIZ-based eco-design matrix was propped in [18]. In another study and also regarding design, a tool that faces the absence of a common vision regarding sustainability during the first phases of design based on key items of TRIZ is proposed [19]. Quality function deployment (QFD) combined with TRIZ was used in several studies in order to achieve a sustainable design [20; 21; 22; 23], while other authors call it environmentally conscious quality function deployment (ECQFD) [24]. A study proposes a sustainability planning platform through a balanced scorecard comprising of QFD, TRZ and abridged life cycle assessment (ALCA) [25]. Eco-innovation can also be fostered by TRIZ. The evaluation and application of the TRIZ methodology are proposed in [26] with the purpose of increasing eco-innovation in small and medium-sized enterprises (SMEs), and the authors concluded that by using TRIZ it is possible to achieve efficient and rapid processes, products, and sustainable services. In [27], a resource-constrained innovation method is proposed in order to produce ideas for new product development based on TRIZ. Fomenting early eco-innovation design for products that integrate case-based reasoning and TRIZ method was addressed in [28]. TRIZ has also been used in conjunction with life-cycle assessment (LCA), and in a study the authors used a graphical ontology in order to guide the designer in mapping the product life cycle [29]. While in another study [30] these authors aim to integrate TRIZ derived eco-guidelines with LCA in order to obtain a sustainable design and process. In [31; 32] the authors propose a reasoning model in order to achieve innovative ideas straightforwardly for designing eco products with simple LCA methods. This finding suggested that using TRIZ could be more helpful for mature products. The link between TRIZ and social sustainability has also been a focus of study, and, for instance, TRIZ and the paradigms of social sustainability in product development are addressed in [33]. On that trend, the authors in [34] propose a conceptual integrative model of Kansei Engineering, Kano and TRIZ in order to foster sustainability in services in which healthcare is used as an example. Another study has considered these models and SERVQUAL by addressing ergonomics sustainability [35]. As can be seen, TRIZ is applied for a wide range of areas related to sustainability. All of these studies address TRIZ and its relation to sustainability. Even though many studies address the use of TRIZ in eco-innovation in many forms, no model of TRIZ with Eco-Compass has been proposed in the literature.
